Where was the earliest fossil egg found?

As yet, we do not have an article on Fossil eggs nor does our fossil article provide much detail. However, these articles by The San Francisco Chronicle on dinosaur fossil eggs [1] and the National Geographic on bird fossil eggs [2] should be of some assistance to you.

Details: There is a thin, roughly cylindrical shell called the vascular cambium, which is where a tree does its growing. The outside of the cambium produces new phloem cells, which do "food" transport. The inside of the cambium produces new xylem cells, which do water & nutrient transport from the roots. Old phloem gets shed with the bark, but old xylem just sticks around, forming a core made of dead cells that provides structural support to the tree. Most trees add a new layer of xylem each year. The old dead xylem layers are the rings one can see on a stump.
It appears to little-old-nonexpert-me that this ability to make a single, strong core out of dead xylem is probably one of the main factors that allows trees to grow so tall. Lots of plants have this phloem/cambium/xylem structure, but in many of the smaller ones, the cambium does not form a single large cylinder, but rather many small ones (vascular bundles). Thus, the xylem is scattered and strength is lost. I imagine this is one reason you will never see (say) a celery tree. On the other hand, the multiple bundles probably allow for faster growth ("growing like a weed"). Interestingly, palm trees have the multiple vascular bundles, but can still form large, strong trunks.
Much of this is hinted at in our tree and xylem articles, but never quite stated. Maybe it should be.

Any Airsofters in the LA county area?
What we have been taught is that electron revolves around a proton because of electromagnetic force of attraction. But this force is same for both the electron and proton. This is when we neglect other forces like Gravitation since it is only 1/100 th times of electromagnetic force acting. Then why do electrons revolve around the protons instead protons can move around an electron??

If two persons both eat the same amount of beef each and every day from the same large pool of cattles, which person is more likely to get mad cow disease in the long run?
I guess Mr. A's risk is much higher than Mr. B's. But could it be possible that by mixing a few thousand dead cattle's meat at a time, the concentration of bad prion would become too low to be threatening? -- Toytoy 03:38, 23 September 2005 (UTC)
I guess it is still unknow how much prion would cause one to be infected. If we hire many vegetarians and feed them infected meat and wait a decade, we may learn what are the minimum prion concentrations to infect 10%, 20%, ... 50%, ... 90% and 100% of people after consumption of a portion of beef. But we simply cannot try this on people ... at least to vegitarians.

To bring a bit of perspective to the whole "mad cow" panic, it's worth remembering that in the 20-or-so years since BSE became apparent, fewer than 160 humans have died in the entire world from nvCJD.

It should be noted that cost reductions also have applications in combating hunger in developing nations. As does creating a GMO that produces more nutritious food than its natural counterpart.
Lastly, I'd note that at least one of your "Risks" arguments isn't quite right. "Killer bees" were not created through modern genetic engineering, but through old-fashioned interbreeding. This phenomenon has been going on for thousands of years and, in general, has been quite safe and successful. A single isolated example is not a good argument against it. And it is certainly not an argument against modern genetic engineering, since it was not used in this case.
Again, I am not arguing a position here. I just saw that your list of "risks" and "benefits" seemed awfully lop-sided. You asked whether there has been a failure of government oversight. I'd say that is quite possible.

A "proof" for the idea that -1=1 was posted on your page about the imaginary number i. I have replicated it in this question for quicker reference:
-1=i*i=sqrt(-1)*sqrt(-1)=sqrt(-1*-1)=sqrt(1)=1
However, your page says that this is incorrect because square roots only work for real, positive numbers. Your page on the number -1 says that -1^2/2=-1 and sqrt(-1^2)=1 therefore 1 cannot equal -1. However, a friend of mine says that this is incorrect because sqrt(-1^2)=sqrt(-1) though -1^2=1; I have written to you in order to resolve this dispute.
Thank you for your time and patience.
There is simply no way to define "sqrt" as any sort of square root function that makes this true.sqrt(-1)*sqrt(-1)=sqrt(-1*-1).
As for your dispute, your friend is wrong. The statement
is false for all ways of defining "sqrt" as a square root function, since this says that sqrt(1) = sqrt(-1), while those two numbers (1 and -1) have no common square root.sqrt((-1)2) = sqrt(-1)
The lesson to be learned from all this is that we don't get to apply supposed mathematical "rules" anywhere we want, but only where they do, in fact, apply. And rules that apply in certain special cases may not apply in general. In particular,
works fine when a and b are nonnegative real numbers. That's what we were all taught in school, and it is correct. However, this does not mean that this applies more generally to all pairs of complex numbers. In fact, it does not.sqrt(a) × sqrt(b) = sqrt(a × b)
— Nowhither 01:10, 24 September 2005 (UTC)
And, regardless of whether it seems right, it is true that there is no nice way to define a square root function on all complex numbers. If you want to be formal, then substitute "continuous" for "nice".

Well, I just got my computer and was trying to open a few video files, so I downloaded some codec packs. The first was ACE mega codec pack. It was great, opened tons of stuff, except this one divx video with some interleaving problem... Well, I removed ACE, and got a few other codec packs from free-codecs.com (k-like, xp and all in 1).
Installed all in 1 first. Didn't work. Uinstalled it. Installed XP. Didn't work. Uninstalled. Insalled k-like. It worked. But now WMP won't open the most basic video files (wmvs), and the automatic download of codecs feature returns an error (no appropriate codec could be found).
So, this sucks. Not even half of my videos are opening right now and I was wondering what I should do. Is there any tool that lets me remove ALL codecs from my computer, so I can get them all again?

I've long had an alternative to the Big Bang theory, which surfaced when I gave an answer to Wikipedia:Reference desk/Science#A Variable Speed of Light hereabove. I'm very much a layman when it comes to this field, but I made a prediction that went against the accepted theories but turned out to be correct, which is a bit of a theoretician's wet dream :) . So I now venture to put this theory before you. Here goes.
As a kid I heard the expanding universe explained as a balloon with dots on it. On that everything moves away from everything else, which is exactly what we observe in the universe. But then I wondered, how do you know a balloon expands? My thought was that you know that because the only alternative is that the room you're in (and everything else) is getting smaller. Which would be silly. The simplest solution is held to be true, which is that the balloon expands. But for the universe there are (by definition) no surroundings to compare with. There is no reference frame, so one has to assume the size of of the universe is given. I couldn't think of a solution then.
But later I realised that you can also compare the sizes of the universe and everything in it. If the size of the universe is given then the stars and such must be getting smaller. Hmmm, stuck again.
Later still I imagined falling into a black hole. I was supposed to get stretched out. But that's seen from the framework of an outside observer. For me, I'm part of the spatial framework that gets expanded. Also, time gets ever slower form the perspective of the outside obeserver, but, again, I live in that timeframe, so from my perspective it will take me forever to fall into the black hole. So for me nothing changes (right?). Except that I see everything around me moving away from me. Hold on, I thought, couldn't that explain the aforementioned phenomenon? What if we are caught in a collapsing (part of the) universe? But then I realised that as things are further away they will accelerate away ever faster. And acceleration is not what happened, right? Stuck again.
Until a few years ago someone (Riess or Perlmutter?) discovered that exactly that is the case. When I heard of this I jumped out of my chair. After the initial enthusiasm I didn't know how to present this idea. No-one would take me seriously. Now, finally, I've found a place where knowledgeable people might be bothered to hear me out. So. Any thoughts on this?
By the way, I don't necessarily suggest we're falling into a black hole. I suppose being attracted to anything sizeable enough will have a similar effect. And since everything is attracted to everything else there might not have to be anything special going on. Though if it's that simple I find it unlikely no-one will have thought of this before. Or have they?
Also, as for the other two bases for the Big Bang theory, I don't have an explanation for the background radiation. The abundance of light elements suggests a fairly 'young' universe, which would still be possible if we're in the middle of the Big Crunch. DirkvdM 09:26, 24 September 2005 (UTC)

Hello:
Why is it that only one side of the moon always faces earth? If you take an apple and rotate it around a lamp you'll find of you keep the axis facing the same direction all parts of the orange will be reflected as it revolves around the lamp. But the moon has to slowly rotate in such a way that it keeps its one side visible to the earth and as far I can tell it has been showing the same side of the moon for thousands of years? This can't possibly be a coincedence, but I don't see how Newtonian laws of gravity apply to this question.
Will Sperry Kunming China
To begin with, do you understand why the ocean has tides? The Moon pulls a bit more on the water close to it, than it does on the Earth as a whole. So there is a bulge of water on the side of the Earth nearest the Moon. Similarly, the Moon pulls harder on the Earth as a whole than on the water far from it. So the Earth gets pulled away from the farthest ocean, resulting in another bulge of water on the side of the Earth opposite the Moon. And that is why we get high tides during the full & new Moon (or nearly so; the land gets in the way of water flow, which makes it all a good deal more complex).
Now, the Earth pulls the same way on the Moon, "trying" to create a bulge on the near & far sides if the Moon. This has two effects. First, if the Moon didn't always show the same face to the Earth, then as it rotated, it would get squashed in various directions. The resulting friction would turn part of its rotational energy into heat, thus slowing its rotation (relative to the Earth). Second, if the Moon is not a perfect sphere, it would have a tendency to settle in a position in which the bulge(s) faced either toward or away from the Earth.
And that is what happened. The Moon is not a perfect sphere, tidal friction slowed it's rotation, and it settled in a position in which the bulges are aligned toward/away from the Earth.
Of course, similar logic would suggest that the Earth should always present the same face toward the Moon. Why doesn't it? First, the Earth is bigger, so it has more angular momentum to keep it going. Second, the Moon is smaller, so there is less tidal force to slow the Earth down. But if we wait long enough, and no other factors intervene, and the Moon stays in its current orbit, etc. (which won't happen), then the Earth should eventually present the same face to the Moon all the time.
— Nowhither 11:21, 24 September 2005 (UTC)
Why would there be a specific bulge? (Maybe)Once upon time, millions of years ago, was the moon rotating around an axis and the earth's gravity finally slowed it down, to its current rotation? And why would friction effect the moon when it is in space where there is no friction? The tide analogy seems obvious because of the fluidity of water, but the solidity of the moon would seem to make a bulge less of a factor as the tides are effected by the moon. Over millions of years do these factors create slight changes that finally effect a final result?

Since my professor doesn't seem to intend on replying to my e-mail (this is not a homework assignment, but I have to understand the basics of this silly language in less than 10 days before the first test), I'll throw this question to fellow Wikipedians, whom I hope some know Prolog.
Given this file:
line(2, 2, 4, 5).
line(1, 2, 4, 5).
line(1, 1, 4, 4).
linelen(line(X1, Y1, X2, Y2), Z) :- DX is (X2 – X1)**2, DY is (Y2 – Y1)**2, sqrt(DX + DY, Z).
I am able to do this:
?- linelen(line(1, 5, 3, 6), Z).
And get a valid result for Z. However, if I attempt pattern-matching:
?- linelen(line(A, B, C, D), Z). or ?- linelen(L, Z). It gives me ERROR: Arguments are not sufficiently instantiated. (I've also tried all sorts of other things, all of which give me this error -- this is the most basic, though, where I began trying to write this function).
Why is it not pattern-matching? I expected it to give me the lengths of each line that I declared as previous facts, but for some reason, it is not doing this. Is there something I'm not understanding right about how pattern matching works in Prolog? I think I understand it pretty fine, but it's the syntax that seems to be killing me. What would be the "correct" way to implement this function?
Also, could anyone recommend a really good book about Prolog? Our course textbook is the one written by Mr. Ivan Bratko, who I understand had a hand in standardizing Prolog, but unfortunately it's not really that good a textbook when it comes to explaining things clearly. A good example of a programming language manual that "clicks" with me is the one for Lua written by Roberto Ieruschamily(sp?) -- are there any Prolog books like that out there? --I am not good at running 00:22, 25 September 2005 (UTC)

It is true that we are not very happy with large computer-based proofs, because they are not very elegant and they give us little insight into what is really going on. Further, they force us to base notions of absolute truth on whether some particular electronic circuits were functioning properly.
However, the most important problem with the mid-1970s Appel-Haken-Koch proof of the Four Color Theorem is that no one has ever checked it independently. A group of researchers (Robertson, Sanders, Semour, Thomas) decided to do the checking in the early 1990s. They eventually found it easier to produce their own computer-aided proof, which followed similar lines, although it was a bit simpler. This proof has been checked independently. Further, you can download their program and run it yourself.
So now we can be quite confident that we do have a proof of the Four Color Theorem. And mainstream mathematical culture generally accepts computer-aided proofs these days. Although we still prefer traditional proofs, for the reasons of elegance and insight that I mentioned above.

Hi. Are the Orcas in the fiords of Norway there yet? Thanks.
The subject pretty much sums up the question.
I'm assuming you meand "dual axis". Color temperature provides a hint: "Color temperature" is sometimes used loosely to mean "white balance" or "white point". Notice that color temperature has only one degree of freedom, whereas white balance has two (R-Y and B-Y).. So I'd guess (never having seen the expression before, and only coming up with a single Google hit) that simpler cameras use a one-dimensional adjustment (color temperature), calling it "white balance"; while fancier ones (like the Canon EOS series, the only context in which Google found something) have a two-dimensional adjustment. --jpgordon∇∆∇∆ 22:22, 26 September 2005 (UTC)

Depends upon how much acid, also depends upon what kind of acid. Small spills can be cleaned up via adding a base, or alkaline substance found around the home. Typical substances are Sodium bicarbonate, ammonia and lye. Sodium bicarbonate will froth profusely in contact with acid, ammonia can be toxic in large concentrations so make sure you have plenty of ventelation, lye will burn the skin if left in contact for a prolonged period so make sure you wash it off or even wash with a solution of vinegar. Some acids, like prussic acid are deadly poison so get out of the area fast, others like acetic acid found in vinegar are not very dangerous, so washing with water would be good enough. Large spills often are taken care of by nature herself as carbonates in the soil react and neutralize the acid.
Still a lot depends upon the acid, how much and where the spill was.

I understand that carbon dioxide buildup in the body is what triggers "air hunger" in a heavy carbon dioxide environment, but that a helium environment wont cause such a reaction, leaving a mamal unable to sense the loss of air and therefore vulnerable to suffocation. Is this true?
No, no, no, DrBob. The CO2 in the blood that drives breathing comes from body metabolism, not the surrounding air. Prevention of breathing it out is what makes you feel out of breath. Breathing is also driven by hypoxia or rising acid level, but these drives are weaker than the CO2-linked response. alteripse 21:09, 27 September 2005 (UTC)
Nothing prevents you from breathing out CO2 in a low oxygen atmosphere. That's why people can sometimes die of hypoxia as long as they can exhale CO2. alteripse 00:21, 28 September 2005 (UTC)
Let me see if I can make it clearer. There are at least 5 types of control for the physical act of respiration: (1) voluntary breathing, e.g., blowing at something or talking; (2) involuntary neural control based on a rhythm of breathing controlled by neuronal pacemaker cells in the medulla; this is what keeps someone breathing in a vegetative state and why a brain injury that affects the medulla can kill someone; (3) chemical control by arterial blood carbon dioxide levels; rising levels stimulate breathing; (4) chemical control by arterial blood oxygen levels; falling levels stimulate breathing; and (5) chemical control by arterial blood acid (pH) levels; falling pH stimulates breathing. The CO2 and acid in the blood are generated by aerobic metabolism of body cells no matter what you are breathing.
Exhaling CO2 does not depend on the content of the ambient atmosphere but whether your lungs are working and your airway is unobstructed. Physical obstruction of breathing by a hand over your nose and mouth will prevent you from exhaling CO2 and inhaling O2, as will prolonged closure of the epiglottis as occurs in drowning; as will failure of respiratory muscles (e.g. Guillain-Barre syndrome) or severe lung disease (e.g., adult respiratory distress syndrome). In all these cases you die with a high CO2 level in your blood, low pH, and low O2 level.
However if nothing impairs your breathing but the oxygen is removed from the air, you will continue to exhale CO2 but your O2 level will fall. Most people and animals sense this before they become unconscious from hypoxia but not always, and increased breathing of a low-oxygen atmosphere does not improve the oxygen levels and the person or animal will become unconscious fairly quickly. This is why people are overcome by collections of heavy gas in sewers or chemical tanks, and a rescuer can die of hypoxia before extricating the initial victim. Just before their respiration becomes impaired, they will have a low blood O2 level and a low CO2 level; as the hypoxia affects the medulla and breathing ceases the CO2 and acid level will abruptly and rapidly rise.
The earth's atmosphere is about 21% O2 but less than 1% CO2. The rest is mainly nitrogen, but you can substitute all kinds of other gases like helium as long as you supply at enough oxygen and the other gas is not intrinsically harmful (like carbon monoxide). CO2 is not a damaging gas, but breathing an atmosphere of 21% O2 and 79% CO2 would result in rising levels of CO2 and acid in the blood because gas exchange in the lungs depends on a gradient between blood and ambient air.
Of the chemical controls, the CO2 drive is stronger than the O2 or pH drive. All of the chemical controls can gradually habituate to altered levels (e.g., as occurs in emphysema) and sudden changes can cause problems. A sudden drop of blood oxygen that causes hypoxia will impair and damage the brain in minutes. A sudden drop of CO2 (e.g., from hyperventilation) will upset the acid/base and cation balance of the blood and can cause a variety of symptoms, including panic. A sudden rise of CO2 in some circumstances can actually impair brain function and the neural drive to breathe: this is referred to as "CO2 narcosis".
Finally, it seems that all air-breathing vertebrates have similar respiratyor control mechanisms. Antoine Lavoisier discovered some of the properties oxygen by observing the effect on mice of altering their ambient air.

How does point nine repeating (.9999…) equal one?
One more way of looking at it: a real number is, by definition, not simply a sequence of decimals (in which case 1 and .999.. would be distinct numbers), but actually equivalence classes of sequences of decimals, where two sequences are the same if one has all 9s as its final digits and matches the other in all the other digits before the 9. The reason for wanting them to be the same is because the associated geometric series will converge to the same number. But of course that's not rigorous. You need to define the reals before you can discuss convergence of series, otherwise you'll have no guarantee of convergence to any number (the reationals are not complete). So the rigorous answer to your question, "why are the numbers the same?", is simply "because they are defined to be the same". -Lethe | Talk 16:21, 3 October 2005 (UTC)

One of the reasons often given for not teaching Intelligent Design is that it is "not scientific", which as far as I understand means it cannot be experimentally disproven. What makes evolution "scientific", or rather what experiment would disprove evolution?
Science restricts itself to hypotheses, theories, mechanisms, and processes that are consistent with our knowledge of the material world and explicitly excludes claims about supernatural processes or knowledge. Science cannot and does not claim that God does not exist or did not create the world, only that such claims cannot be evaluated from a scientific perspective and are not likely to advance our scientific understanding of the material universe. Since first proposed, an enormous amount of experimentally verifiable and directly observable evidence has supported the validity of the basic process of evolution and no evidence strongly undermines it. It is possible to imagine that several million years ago, several thousand years ago, or several minutes ago God created the world exactly to seem as if evolution is occurring, but none of these hypotheses fit with other scientific knowledge or seem likely to advance other scientific understanding or can be proven or disproven scientifically.
The objections that most intelligent people have with the idea of Intelligent Design are that it is (a) presented dishonestly (as not being intended to promote fundamentalist Christianity), (b) confuses people about what science is (by incorporating miracles and supernatural processes in scientific knowledge), and (c) misrepresents our current understanding of evolution (which is both dishonest and confusing). Most intelligent Christians make a distinction between evolution as a scientific way of understanding the changes and interrelationships of living things on earth, and most intelligent scientists do not claim to be able to scientifically prove or disprove the existence of God or whether he had a role in the formation or history of the universe. Does that help? alteripse 15:41, 29 September 2005 (UTC)

Human beings (and possibly all vertebrates) have two bones parallelly placed in their limbs: Radius and Ulna in the arms and Fibula and Tibia in the legs. But why two bones instead of one? I mean why did the humans body evolve in such a way as to have a pair of bones? What advantage does having two bones have over one single bone that is strong enough ?
In additions to the excellent reasons given above, two bones work better than since our joints do not freely rotate in all directions. Think about pronating and supinating your hand when your elbow is held still at 90 degrees. Try to imagine a one bone system that would allow that. You will get the idea.

Hello. And thank you for your time first of all. Ill just cut to the bone.
I have found capillary tubes on the internet at .4 -.6 mm ID. What i would like to do is bend it about 120 deg. Actually i would like to bend sevral tubes together. The thing is im not to good at working with glass. If i were to heat the glass to the point i could bend it i fear i would collaps the id or at the least distort it to the point it would no longer work. With a copper pipe you can simply place a spring slightly larger than the OD of the pipe so as to hold its "roundness" as you make your bend. But with glass and being so thin to begin with i think i would have problems getting and keeping the glass hot enough withought being to hot to get a good bend. If possable i would like to bend say 20 tubes together and hopefully end up with extra capallary paths by default in the space between the tubes. But i also think bending more than one at a time would stretch the outer tubes or crimp the inner ones. And heating all evenly could be tricky.
My question is: How could i bend capillary glass and not destroy the id. And if possable how could i bend more than one at a time so as the bend is matched? How shallow of a bend would i need? And how could i bend more than one so that they could be stacked together close enough. Preferably a way i could do this in my garage without spending a ton of money. : )
Also all the searches i find on capillary action use water. I have read that water and glass is one of the best ways to observe capaillary action as they work great together. But i cant seem to find to much information on other liquids capillary properties. For example does mercury work well in a capaillary sence and what material tube would work well for that. It seems to have good surface tenssion. --68.42.226.224 01:41, 1 October 2005 (UTC)

Am advised that before a clinical study utilizing an 'already approved' medication (to kill a newly discovered microorganism) will be 'monitored' by a medical Institutional Review Board (IRB) – an application for its (the medication's) "Off-Label Use" must have been submitted to the FDA.
A means of potentially eliminating the No. 2 killer, heart disease, (including stroke, TIAs, carotid artery blockage and other cholesterol related vascular disease) has been discovered and utilizes a well known, broadly used antibiotic to kill the microorganism that causes vascular plaque buildup and other 'unwanted calcium' related conditions.
Can you tell me the procedure for filing such an application with the FDA – for "Off-Label Use" of a medication and where I can find a copy of the application form?
Thank you.

Most likely, your IRB is requiring you to submit an IND (Investigational New Drug) or NDE (New Drug Evaluation) application with the FDA [19] because your study does not qualify for a waiver. If you don't already know how to do this, you need help from someone who has experience with the process. It's not a task for the weak-hearted, and it can't be done on the basis of advice from Wikipedia! You can start by asking your IRB for additional information. You might also have a look at the FDA site. (I'm assuming you know about previously conducted studies which have failed to show benefit from antibiotics with regard to plaque; (2 studies were published in the April 21 2005 issue of the New England Journal of Medicine) – you'll need to include a literature review in your application.)

You pick up the telephone and you call your hospital's IRB. You have to take a several hour course on ethics of human research in order to be a principal investigator for a research project involving people. Then you have to write up a description of your trial (the protocol) and a sample informed consent form. Then you make an appointment to present it to your hospital's IRB at one of their regular meetings. Be prepared to discuss relative risks and some skeptical questions if you are planning to offer your experimental treatment instead of a standard treatment. Remember, part of ethical resarch is designing a study that will have the power to provide a useful answer for the time, trouble, and potential risk of the subjects. What trial design did you have in mind? What recruitment method-- your patients, newspaper ad, referrals? I suspect I am not the only one who thinks anyone who is asking wikipedia how to do medical treatment research is pretty unlikely to know what he is doing or have the resources to do it, but we'll be happy to tell you the procedure. alteripse 01:49, 2 October 2005 (UTC)

Mammalian metabolism tends to convert most dietary nutrients into the simple sugar glucose before it degrades it and captures the chemical energy as ATP (via NADH + H+). Hence a drink containing glucose is a perfectly acceptable way to provide the body with an energy precursor. I suppose it beats an iv injection of ATP !

I know this may not be the best place to ask this question, but before going to a physician I wanted to hear your opinion. I'm a 19 year old frequent sportist (mostly upper body strength, rarely cardiovascular exercise) and, since this summer when, after playing more than 2 hour long everyday soccer matches I've been experiencing lack of strength and sometimes even pain after doing basic leg exercises, such as running or jumping. Do you have any idea of why can be this happening? PD: Sometimes, while on computer, I experience a tingling sensation in my legs.
Thank you in advance.
The differential diagnosis for this symptom is lengthy and ranges from trivial to slowly catastrophic. See a doctor but before the visit try to think of objective evidence for a real change (e.g., substantial difference in how far you can walk, bicycle or climb stairs compared to 6 months ago) rather than subjective differences (I feel more tired when I...). Second, think about whether this is just a leg problem, or leg and foot, or whole body strength change. Third, your doctor will be trying to distinguish between subjective versus objective weakness, earlier fatigue versus decreased strength, localized versus generalized weakness, strength only changes versus strength plus changed sensations. Fourth, think about any other new symptoms or body changes, especially those present for the last few months. Good luck. And for the potential hypochondriacs out there in audienceland, I would like to emphasize that purely subjective changes in strength and energy rarely signal serious disease.alteripse 16:21, 3 October 2005 (UTC)
See alopecia. Differential diagnosis depends on pattern and degree of loss (i.e., visible bald areas versus more hairs in the shower drain or brush) and ranges from perception to normal androgen effect which will culminate in male pattern baldness to a variety of less common causes of localized hair loss to (rarely) some systemic (whole-body) diseases of metabolism or nutrition.

I am a bit simple and find it hard to follow articals on physics when mathmatical formula are used. I understand that maths is the language of physics but as soon as the numbers come up it might as well be written in another language. Anyway I'm going to attempt to ask a question which I hope doesn't sound to stupid and I hope some one can answer it in a way that I can under stand.
The question is about the speed of gravity. I read that two heavenly bodies ie. earth and moon, are tied together by the pull of gravity and that if one of these bodies were to instantly vanish then the gravitional pull between them would also vanish instantly. This affect would be instant regardless of the distance between the two heavenly bodies. The argument also exists that nothing can travel faster than the speed of light. So there is a conflict between the two schools of thought.
My question is probably answered in some mathmatical jargon some where but.... if gravity existed as a sort of cloud around a heavenly body and another heavenly body in that cloud were to vanish what sort of affect would that have on the heavenly body that stayed behind? Or to look at it another way, if I pulled a pebble from the ocean would any of the other pebbles in the ocean notice?
The vanishing object would suffer a collapse of it's gravitional field and the remaining object would continue to exert the same degree of gravitional pull as it's own mass would allow. The only thing to change would be the interaction between the two.
The question then is is an interaction an actual physical thing in it's own right? I can interact with another person in a room with out any direct transfer of energy between me and the other person. A wink or jesture could transfer information either locally or across streets or fields and should the other person vanish my own condition would remain the same.
I'm not realy sure about the whole argument because in order for the moon to be released from the pull of the earths gravity the earth would have to vanish...which ain't going to happen...not in this universe.
I don't think this is realy a question but more like just a thought which I hope more learned people will comment onEye 22:14, 3 October 2005 (UTC)
According to Einstein's model of gravity, changes in the gravitational field propogate at the speed of light. In Newton's theory, changes propogated instantaneously. Newton knew this about his theory, and disliked it, as have most people since. Now that Newton's model is 400 years old, and we have a more accurate model, there really isn't any school of thought that says changes in gravitational field are instantaneous. -Lethe | Talk 00:08, 4 October 2005 (UTC)

Einstein's General Relativity saids that space-time continuun is simply a piece pf fabric, when there is a massive object in space-time, it will curve the fabric of space time, like a bowling on a piece of rubber sheet. The earth keeps its orbit because the sun curved the space nearby, forcing earth to follow "the trace" that the sun had curved. Light travels at 300000 m per second, and since only light can maintain the speed of light, gravitational waves cannot act instantaneously if the sun suddenly disappears. Since light takes 8.3 minutes to reach earth from the sun, the "vanish" of the sun will not act instantanesouly.

I have always heard about the glaciers that covered the northern part of the continent during the ice age, and how they transported rock and debris south, or dug out the great lakes. Living in Michigan, I can see where they left moraines. However, I have never heard a good explanation as to the force that propelled these glaciers forward. There is no real elevation gain from Michigan to the North Pole. It's not like these gaciers were flowing downhill like they do in mountainous regions.
Michigan was at the edge of the Laurentide ice sheet that created the Canadian Shield, so you need to read the ice sheet article which explains how such large masses of ice were able to move.

Hi This is not really a question but more of a request. I have performed some google searches to find a name for my husband's white tuft of hair above his forehead. I found Poliosis and White Forelock. I also found a list of dreadful diseases of which I'm fairly certain he has none. I then tried to find any information possible on Wikipedia and the search came up with zero. I'm just wondering if there are any personality traits (like extreme intelligence or other endowment) that might accompany this somewhat less common physical characteristic. I'd love it if anyone in-the-know could add this subject to your website.
thanks
There are many minor genetic physical traits that can occur by themselves or with several other physical anomalies. When they occur by themselves they have no hidden significance and cause no problems. When they occur with multiple other anomalies, some of those other problems can turn out to cause serious trouble. This combination of anomalies is usually referred to as a congenital syndrome. Other examples of minor physical anomalies that can be of no significance by themselves or can occur as part of a more serious syndrome are little pits in front of the ears, short broad thumbs or fingers, high-arched palate, and indented chest. Finally, there are no personality traits associated with this type of minor isolated anomaly because the only body part affected is that area of the scalp. alteripse 01:44, 5 October 2005 (UTC)

No evidence is available for your specific question because such changes are never done in isolation from other factors that might change lifespan: healthier eating (e.g., reduced fat intake), reduction of unhealthy exposures (e.g., less time with secondhand smoke), etc. There is some evidence that in small mammals those who are allowed to eat less calories daily over most of their lifespan live a bit longer; this appears to be a phenomenon distinct from simple avoidance of obesity but we have no way to extrapolate this to people or to know exactly what the mechanism is. This topic of changing life span by changing daily living habits or eating habits is generally referred to as life extension and much has been published online and in the scientific literature but the quality ranges widely and much of what has been written about people is speculation, opinion, or marketing written to sell a product. Be skeptical. alteripse 10:36, 5 October 2005 (UTC)

Why does hair turn gray or white as humans age?
Perhaps you didn't mean to get into the technical details of how pigmentation stops being produced, but were rather asking why, what evolutionary purpose does gray and white hair serve ? It may be that it serves no purpose, and is just a malfunction that isn't very harmful, so isn't selected very strongly againt. Another possibility is that visual age markers, like gray hair and wrinkles, are in some way helpful to the species. On the positive side, they may be ways to identify older people, who presumably have valuable knowledge and experience to offer, which may help the group survive. A more negative interpretation may be that this helps to identify people who are beyond their ideal fertility age, and thus should be avoided for younger more fertile mates. If either of these is a benefit to marking older people with gray and white hair, then evolution may actually select for this feature. Note that many other mammals share this trait with humans.

Dear Wikipedia Volunteer, I am currently undertaking a research project. For this to be successful, it is important for me to know how to stabilize the frequency of vibrations of the quartz crystal used in an oscillator circuit. The quartz crystal in question is a 14.3183 MHz oscillator, but the output frequency is accurate only till 14.31 MHz (i.e. about 10 kHz). How can I stabilize the vibrations so as to get accurate output frequency in the order of tens of Hz? I would be highly obliged if you kindly post the answer to my query at your earliest convenience, or give me a few references in this regard.

Hello everybody,
I have always been wondering while seeing some nature tv programs or photos or etc that how come trees are able to live in such conditions as in islands where the soil is ssandy and permeable to sea water and these trees most probably have roots that are soaked in salty sea water. Apart from the fact that many trees, as far as I know, could not stand the salt in the sea water, their roots are also not able to breath oxygen, could they? As you see in many commersial photos or educational tv products there are islands where their jungles are only a few meters away from the sea water. How is that?
So please let me know how do these plants survive? Is their roots in sea water at all? It those are those roots adapted to these situations or their is some mgical thing happening there?
I hope i could have been able to explain my question as good as possible.
Thank you for your replies in advance.

Would it be right to say that energy in its pure form is unknown to us? For instance I cannot see the light that passes across my field of view. It seems that we can touch, hear, and see energy but only when it is interacting with the matter of our own bodies, our eyes, hears, or skin and in doing so does the energy that triggers the reaction of our senses changes it form? If so would it not also be so that what ever device we construct to measure energy would have the effect of changing the energy which we try to measure?

Of all the things a person in a modern Western democracy might normally consume as part of a meal, which would kill with the lowest dosage? The test subject is to be fed on the test food alone and is allowed any quantity of water and time for comfort breaks. --bodnotbod 01:46, 6 October 2005 (UTC)
Oooh, fun game. Tricky though. For instance if you include trace amounts of things that we ingest but don't intend to and are not conscious of, the answer would be aflatoxins, other natural neurotoxins like botulinum toxin, or pesticides and other chemical contaminants. We certainly "might normally consume as part of a meal" trace amounts of these things, but it would take only mg amounts to kill us.
Now if you restrict your contest to things that we deliberately and knowingly ingest as food, then alcohol seems a pretty good choice if taken as a single dose (1-3 oz of pure ethanol can be fatal to an adult), but if spaced out it would require a much larger amount. Same for caffeine. However, your allowance for "any quantity of ... time for comfort breaks" would suggest we could stretch out the exposure. So it looks like you'd better impose more rules. alteripse 03:08, 6 October 2005 (UTC)
Of course. You can OD on water or oxygen also. The amount of salt that would kill you if you had access to sufficient water and could take "comfort breaks" to unload some of it would be larger than the mg of caffeine that would be fatal. However it is not a bad suggestion if the contest limited you to a single dose you had to ingest in one sitting. alteripse 04:07, 6 October 2005 (UTC)

When neurotransmitters are released, they bind onto a receptor on the post-synaptic neuron, and open a ligand-gated channel. However, I can't find any details on how or if they 'unbind' so that this channel can reset, and the general mechanism of this occuring. Certainly, the pre-synaptic cell and enzymes have mechanisms to reduce the concentration of neurotransmitters in the cleft, but I don't see how this causes the neurotransmitter molecules to unbind and therefore allow the channel to be activated again. Any details on this mechanism or whether such a mechanism actually exists would be of great use. Thanks. --Lynto008 03:20, 6 October 2005 (UTC)
So when its said that the ligand 'binds' to the receptor, what is really meant is that it 'triggers' the receptor by changing it, rather than actually attaching? More like the ligand turns on a switch than acts like a key? Because the way that the article Neurotransmitters (and just about everything else i can find on the internet) puts it, "The neurotransmitters... bind to receptors.", which to me seems to imply that it attaches somehow and would remain on the channel triggering it until it is somehow cleaved off. I know that this seems a bit pedantic but to someone who is trying to grasp these concepts, it certainly makes a huge difference. Is it true that the ligands don't really 'bind' per se and that there is actually a distinction? If so, this needs to be mentioned somewhere in wikipedia. Thanks again. --Lynto008 07:50, 6 October 2005 (UTC)

There was some talk around here a few days ago regarding the possibility of head transplants. The general consensus seems to be that there is no real reason a head could not be transplanted onto a donor body and live, albeit as a quadriplegic. So the question that occurs to me is this: Is the classic sci-fi/horror staple of a severed head being kept alive, artifically, possible? What about the even more cliched "brain in a jar"? With an oxygenated/nutrient enriched blood supply, under strictly controlled hospital conditions, is there any reason why a human head could not be kept alive, other than ethical ones?

how do electrons(-) not stick together with protons(+)??
A good question to ask is how do neutrons help keep protons together in cases where the absence of neutrons woudl cause the protons to repel each other? Next question is why are neutrons stable in the nucleus when protons are present, but decay into a hydrogen atom when alone?
Protons DO repel each other, but in the nuceus of an atom that repulsion is overpowered by the more powerful yet shorter distance acting force called strong interaction. Electons DO stick to the nucleus (protons and neutrons) of an atom; they are just millions of times BIGGER than the nucleus (visualize cotton balls glued to BBs). At the particle level, heavier things are smaller and lighter things are bigger due to the wave nature of things. The electrons get as close to the nucleus as they can, and their wave nature describes a shape looking like a donut or a sphere or a set of teardrops or other shapes (these are called orbitals, altho nothing is really orbiting). Talk about electrons orbiting is a heuristic in that it is a useful model without being accurate. WAS 4.250 22:04, 10 October 2005 (UTC)

The short answer is that there has been no biological reason to eliminate them. The genes for nipples are very ancient ones common to both sexes of all mammals and are not carried on the Y chromosome. The basic equipment of a nipple is biologically cheap. It is made operational when needed by hormone signals. A defect of nipple or breast development carries little reproductive penalty to a man but a strong reproductive penalty to the other 50% of the population, so nipples continue to be advantageous and evolutionarily conserved. An intelligent designer of course would not bother to design a male with them: this type of trait is far better explained by evolution than by any competing hypothesis. alteripse 19:43, 7 October 2005 (UTC)

There is an interesting parallel in industry, where it is frequently cheaper to make everything the same, even if that means some "additional equipment" is included that was not "ordered". For example, circuit boards are often built with everything and then those options the customer doesn't want are burned off or otherwise disabled. It doesn't seem intuitive that this is efficent, but the cost of producing many different types of circuit boards apparently is more than the cost of destroying unwanted components.

Is there a real difference between a generic and brand drug? I know they have to have the same active ingredient and have to be the same quality and everything, but then why do some doctors insist that a patient takes the brand and not the generic version? And why do so many people claim that the generic version of a drug do not work?
Is there a difference? In a word, sometimes. Most of the time for most drugs and most people a generic will work as well at a lower price. For some drugs in some people the difference between a generic and brand name may more than trivial. The problem is that it is difficult to predict ahead of time. alteripse 05:51, 9 October 2005 (UTC)
Our Generic drug article states that they are bioequivalent to the brand drug. However, in 50% of cases there is no generic drug as the term of the patent has not expired.

If your cousin has a muscular dystrophy there have been many clnical trials of anabolic steroids as well as glucocorticoids and growth hormone.

This is a nicer answer, with refs, than my gloomy one. Note that the "steroids being used to treat muscular dystrophy" in the MDA ref are glucocorticoids rather than anabolic steroids.

I'm interesting in applying for pharmacy school in the next few years, I was wondering how to increase my chances of getting in. I know good grades and a good PCAT score are important and also volunteering in a pharmacy, but what else can I do to increase my chances of getting in a good school?
Also, what questions do they ask at the interview? Thanks
Here is the same advice I would give if you asked about medical school or veterinary school. Concentrate on your grades, especially math and science. Most of the applicants whose grades and scores are within 10% of the average for last entering class will be offered admission, as will some of those whose grades and scores are below that. The principal purpose of the interview is identify unusual positive or negative characteristics that they cannot easily determine by the paper application, or cannot legally or publicly admit to using. Many of these characteristics are those you don't have control over. Another purpose of having an interview is to introduce a subjective element into the process so that taking one person over another with higher numbers can be justified.
If your grades and scores are at least average for the entering classes for that school, the prinicipal purpose of the in-person interview is to detect a disqualifying characteristic. This may differ widely depending on time, place, and local circumstances. One example might be race. Another might be an inability to hold a basic conversation and communicate. Another might be an appearance that suggests potential problems fitting in with the class and reflecting positively on the school. Another might be an extreme disability or an apparent mental illness. Another might be an indication that you would be unlikely to accept an offer of admission. In other words, the admission is yours to lose by the interview.
On the other hand, if your grades and scores are substantially below average for their usual entering class, the principal purpose of the interview is to look for an undetected asset. This may differ widely depending on time, place, and local circumstance. One example, especially in the US, may be race. Another might be an unusually impressive or attractive personal manner. Another might be to confirm other non-quantitative accomplishments. Another asset might be a family connection with the school or something to convince them you are more likely to accept and complete school than the other below-average candidates. Another might be wealth or political connection that could be of advantage to the school. In other words, a small number of students with well-below-average scores will win admission based on other things detected at the interview.
In other words the exact answers to the questions are not the point; it is the chance to detect other things. Work hard so you are in the first group and don't worry about the interview. alteripse 11:43, 8 October 2005 (UTC)

In physics we've just been learning about the wave-particle duality of electrons and it made me wonder – can the wave 'side' of an electron be polarized like light? And if not why not, is it not a transverse wave, is particle physics just too abstract at this level for us to understand or what? ;) --BigBlueFish 19:54, 8 October 2005 (UTC)

that hot air rises and cold air sinks. I also under stand that the same convection forces are at work in the earth and cause magma plumes to rise up to produce volcano’s. Where it all falls apart for me is that as gravity is at work on hot air in that when it cools it pulls the cold, dense air, back to the ground. How does this work in the earth when the force of gravity diminishes the closer you get to the centre?--Eye 21:40, 8 October 2005 (UTC)
-Lethe | Talk 23:33, 8 October 2005 (UTC)
That’s a better way of putting it …there is no net gravitational force at the centre of the earth…which I presumes means that the mass of the earth above the point of centre pulls up in all directions causing the illusion of weightlessness of any object the happens to occupy the earths centre. Mmm…anti-gravity? :-) The force of gravity must exist then, like a crust around an object with mass like the earth. The maximum pressure must be exerted from near the surface and weaken towards the middle as the increase of mass above a given point pulls up on the mass below reducing the pressure. There should then be a neutral point be where the mass above a certain point would equal the mass below. A sort of gravitational boundary layer and this point would be determined by mass not size, i.e. that point would not be equal distance from surface to centre. Would this be where the iron core begins, and if so could the iron core be colder than people expect if the pressure on it is weakened by lower gravitational forces? --Eye 19:49, 9 October 2005 (UTC)
On the page Talk:Solipsism there is mention of a quote I've been looking for for some time.

Why is alcohol so fattening? ♥purplefeltangel (talk) ♥ (contribs) 03:18, 9 October 2005 (UTC)
(after edit conflict)
Or, to put it another way. The yeast, being suck in an environment with no oxygen (by our design since we want the alcohol) relies on this trick where they can get a tiny amount of energy by doing a metabolism that results in alcohol as its end product. They do this because a little energy is better than starving to death. Later, we drink the stuff and we are able to extract the rest of the energy that the yeast was not able to get to. Since the yeast gets only about 6% of the potential, it is a good way to fatten oneself up. Qaz (talk) 04:00, 9 October 2005 (UTC)

I recently heard that an average hurricane unleashes an amount of energy equal to five times the worldwide annual energy consumption of humans (still can't believe it – did I misunderstand?). I understand that that energy comes from the temperature difference between the water and the air. So naturally I thought if this energy could be harnessed. There are two obvious advantages, one being the energy source and the other being the prevention of hurricanes. The Ocean thermal energy conversion article is about temperature differences between different parts of the water, which is something different (or is it really?). Would something like this be plausible? DirkvdM 18:12, 9 October 2005 (UTC)
The energy from the sun that warms the oceans is currently used to power vast ocean curents that help equalize Earth's temperatures, create hurricanes and other weather patternes, and cause vast amounts of fresh water to be distributed over the face of the earth in the form of rain and snow. The energy is not going to waste. WAS 4.250 22:27, 10 October 2005 (UTC)

Drinking enough to cause seizures and unconsciousness (water intoxication) is not so rare. There are plenty of case reports in the medical literature, including a few with fatal outcomes. The amount to induce unconsciousness varies by body size, ambient conditions, and starting degree of hydration, and whether alcohol or various salts or sugars were in the water, but would be much smaller than half your body mass, more like 5-10 liters of pure water chugged in rapid succession for an adult. alteripse 18:04, 10 October 2005 (UTC)

I have been using Mac PCs since I was about four and Windows 9x since I was six. (I'm fourteen now.) I am now a Windows XP user. I consider myself to be fairly proficient with using computers and not screwing anything up, and recently I have been looking into installing a Linux distro on my older computer. I'm leaning heavily towards Ubuntu because I know for sure it has a GUI (which, sorry, is a requirement for a newb like me), is customizable and is, so I hear, easy for newbies. However one of my friends insists that I should get Suse, because "Ubuntu is for people who know what they're doing" and "Suse comes with more programs." I find this to be rather dubious, but I would like a final answer on this one -- should I get Ubuntu or Suse, or some other distro entirely?

I just noticed this question comes from the same address as the next, on anticoagulation, so they are probably related. One of the big risks after a hip fracture comes from prolonged immobilization – this is one reason for anticoagulation. You might want to look at the links from our hip fracture article. The answer to your question depends on the type of fracture, whether surgery has been performed or is contemplated, and to some extent on the health and age of the person with the fracture. Surgery and rehabilitation are common treatments for hip fracture. - Nunh-huh 02:55, 11 October 2005 (UTC)
In short: "thinning the blood" means making it less likely to clot (it doesn't change the blood's viscosity). Coumadin, also called warfarin, does this by reducing the amount of clotting factors in the blood, by reducing the amount of certain clotting factors produced by the liver (namely, the vitamin-K dependent factors). Because it takes a few days for this reduction of clotting factor production to show up (when coumadin is taken in therapeutic doses), coumadin isn't useful in situations where blood must be "thinned" quickly: often heparin is started for short term anticoagulation and continued until coumadin's effects have been established. Our articles should tell you more, or you can ask any unanswered questions here if you like. You might also want to take a look at anticoagulant, and at antiplatelet drugs (which work to prevent clot formation, and are not blood thinners, which work by anticoagulation). - Nunh-huh 02:49, 11 October 2005 (UTC)

Eyes have similar limitations, that's why we don't see stars during the day, or in brightly lit cities at night, they are drowned out by the light nearby.

I have been trying to research leptin, and only come up with sites trying to sell me some thing. Only this site, so far has provided concrete information. I would appreciate anyones comments on this.
You can raise your leptin levels by gaining body fat. Leptin is produced by adipose tissue cells and secreted into the blood. Blood levels of leptin serve as a signal to the brain and other systems in the body indicating the amount of body fat. Fat people tend to have higher leptin levels than thin people. alteripse 17:29, 11 October 2005 (UTC)

Just to correct some of the above statements: mass and energy are two different forms of the same thing. Mass and energy are interchangable at a ratio of E = M *C^2, where E is energy, M is mass, and C is the speed of light. (So a small amount of matter produces an enormous amont of energy.) However, this matter to energy conversion only takes place in nuclear reactions (that is, reactions that modify the nucleus of an atom). The only place you can find such reactions are inside stars, inside nuclear reactors, or at ground-zero of an atomic-bomb blast. Energy-to-matter conversion is possible (I think), but off the top of my head, I cannot think of any situations where it occurs. →Raul654 21:17, 11 October 2005 (UTC)

What are the effects of taking or producing high levels of estrogen? What are the effects of taking or producing high levels and low levels of adrenalin?
Dismas, 99.99% of people producing or taking "high levels" of estrogen around the world are females, not sex-changing males. Effects of estrogen depend on age, sex, and hormonal status of the person, how high the levels are, the duration of high levels, whether risk factors might be present that would amplify the effect, and whether a progestin is taken also. If you want something more specific, you will have to give us more to work with.
Effects of excess adrenaline depend primarily on how high, for how long, and whether the person has risk factors that would amplify effects. The most common effect of acute excess would be heart pounding, anxiety, tremor, pallor, sweating. Chronic excess occurs with pheochromocytoma and can include episodes of the acute symptoms, plus hypertension and eventually damage to heart muscle.
Effects of low adrenaline depend on whether deficiency occurs gradually or abruptly, and whether there are additional hormone deficiencies. In a healthy person, gradual loss of adrenal medullary function produces little in the way of symptoms, but for some people it can produce orthostatic hypotension in certain circumstances, or diabetic hypoglycemia in someone who takes insulin.
So what is your specific concern? (and don't tell me Dismas guessed it, or he gets to give you a more detailed answer). alteripse 23:29, 11 October 2005 (UTC)

Does NZ import its juice? That is probably the reason.

Well thanx for all ur replies. 1. I dont think that broadcasting of two stations on same frequency is permitted. The station I am supposed to hear is the national broadcaster and uses same frequency all over India.
2.Well if reflections are cancelled out by a potential radio reflector around then how come I hear a different station at the same frequency.
How many different spanning trees does a complete graph have?- anon
Here's an easy way to answer questions like this with a minimum of thought: work out the values for some small cases and then look up the resulting sequence in the On-Line Encyclopedia of Integer Sequences. In this case (assuming the nodes are distinguishable), graphs with 1,2,3,4 nodes have 1,1,3,16 spanning trees respectively. Look up the sequence 1,1,3,16 in the OEIS and you'll find OEIS:A000272, "Number of spanning trees in complete graph K_n on n labeled nodes", together with the formula.

Why do all heavenly bodies rotate? --210.214.228.78 12:36, 12 October 2005 (UTC)
A star's rotation and it's planets' rotation and revolution are all a result of the rotation of the gas and dust cloud from which they formed. As they contract into smaller spheres, any small rotation is greatly magnified by the conservation of angular momentum, which means smaller objects must spin faster to have the same amount of "spin energy". Similarly, galaxies increase their spin rate from the original gas and dust clouds from which they formed, as they contract. The question then arises as to why these systems had any spin initially. Any system with nonuniformly distributed matter travelling at various relative velocities will inevitably lead to cases of rotation. (For example, imagine two stars going straight toward each other with a slight offset that capture each other to become a rotating binary star system.) But, this in turn leads to the question of why matter isn't evenly distributed in the universe. We don't know the answer to that, yet. StuRat 16:51, 12 October 2005 (UTC)

Yes, this is homework, but I needed help with just one line of code, if any of you are familiar with matlab. Here was the question:
%% Write a matlab function called fileToStruct that takes in a file name %% (with extension) and returns a structure array. The file can be either a %% .xml file or a .txt file. %% If the file is a .xml file, it is an excel spreadsheet containing rows %% and columns of data. You have to copy all the data from the spreadsheet %% into a structure array. The first row in the excel file contains the %% fieldnames of the fields of the structures. The second row onwards %% contains data to be contained in the different structures of the %% structure array. The value in each cell must be saved in the field %% specified in the first row of that column. The first row (field names) %% of the excel file contains only strings. The second row onwards can have %% either strings or numbers. However, each column will contain only one %% type of data (i.e. either numbers or strings). The attached figure %% (ques1.jpg) helps explain what you have to do. %% If the file is a .txt file, you have to do the exact same thing, except %% that the data is in this text file and it is tab delimited. %% Notes: %% 1) The excel file contains only 1 sheet. %% 2) You do not know how many rows and columns contain values %% 3) The name and number of fields (first row) can be different for %% different input files.
The question I have is this:
I have a text file as shown below: (tab delimited)(each name starts a new row, but i'm not familiar with wikipedia formatting, so it should be a 4 column, 3 row matrix.

I know that plants use nutrients from the soil in order to grow. What I'm wondering is if the amount of nutrients is limited. Suppose a farmer— an ancient or medieval one, not a modern one— uses a given plot of land for growing crops. Do the nutrients in the soil get "used up" by the crops, to the point where it eventually won't be able to support new plants? If so, how long can a given chunk of land be used for growing crops? If not, then can a farmer use the same soil over and over again?
I realize that these are rather broad questions that could have complicated answers, but I don't need all of the details. I'm only using the information to create the history of a fantasy world in a novel I'm writing, so vague generalities are fine. —Saric (Talk) 01:14, 13 October 2005 (UTC)
There are really a lot of variables here, depleting the nutrients in the soil would vary with the type of soil, crop management practices – like crop rotation which can restore some nutrients to the soil, the type of crop grown for example legumes can grow in nitrogen poor soil which other crops could not grown in since they form symbioses which give the nitrogen, and weather conditions are just a few things to consdier. The level of technology would also affect how much people understand this, for example in some parts of Papua New Guniea they cut down a small section of rainforest, grow their crop there for a few years, then move on to a new spot since the land is not as productive after a while, whereas in places like the US a farmer would just apply fertilizers to maintain a level of productivity.--nixie 01:24, 13 October 2005 (UTC)
Another way that nutrients are replenished is through periodic flooding. Seasonal flooding deposits silt loaded with organic matter on floodplains adjacent to the river. (This process made the Nile Delta highly fertile farmland for thousands of years. Unfortunately, construction of the Aswan High Dam has ended the annual floods.)

Other things affecting the ability of soil to sustain agriculture for long periods is exposure of the area to recent (in geologic terms) glaciation or volcanism. Qaz (talk) 05:33, 13 October 2005 (UTC)
This is a partial repetition of what has already been said, but it is mostly a matter of putting back in what you take out. Manure does that (ground > plant > cow-or-whatever > dung > ground). Which is also the way it works in nature (leaves falling on the ground get turned into fungus dung or something). But if you constantly grow the same crop you take out the specific nutrients that that plant needs, and manure isn't usually that specific (or is it ever?). It isn't usually natural to have a long-lasting monoculture (except on poor soils, ironically).
Tropical rainforests are different. Over time the plants (trees) have absorbed all the nutrients in the soil. Anything that falls on the ground is absorbed again before it can sink into the ground. Which is why rainforest trees don't have roots that grow deep (there's nothing there) but spread out with buttresses. So if you take the trees out you're left with almost dead soil. I suppose it might work if you left all the trees to rot and then dig the remains into the ground (and maybe let that stand for a while). But that would take years and people aren't usually that patient. DirkvdM 08:46, 13 October 2005 (UTC)

You's hit the water very hard because of the surface tension of the water.--Shanedidona 03:15, 13 October 2005 (UTC)
A minor physics nitpick—you're not hitting the water hard because of its surface tension; you're hitting it hard because of the water's inertia and viscosity. When you come in contact with the liquid surface, your body rapidly displaces water down and sideways to make room for itself. Since your density is roughly equal to that of water, every kilogram of your body you immerse means a kilogram of water that has to get out of your way. If you fall from a significant height, when you hit you need to move a lot of water very quickly. That transfer of kinetic energy from your body to the surrounding water is fast and painful.

But how to load dynamic libraries common to the system, such as svgalib, seems to be even less documented in these interpreter implementations, so I'm at a stalemate here. I've fallen in love with this language this past month but I'm becoming quickly frustrated with the fact that LISP is looking more and more like a souped-up, glorified shell scripting language to me than a full-blown language that can easily do what C/C++ are capable of in terms of utilizing kernel system calls for more serious applications.
Are there any LISP/CLISP interpreters out there which allow for easier hardware-level programming and has easy-to-understand and well-versed documentation about loading dynamic libraries and everything else I need to do? Considering how old this language is I thought it might be easily done by now; any language older than C should be just as capable of OpenGL, if you know what I mean. I'm also at the point where I'm open to spending money on a proprietary LISP suite with nonstandard predicates and functions (equivalents of ioctl, etc) if I have to get these features. --I am not good at running 17:43, 13 October 2005 (UTC)

Sometimes when playing a video game on an Xbox, PS2, or other console the frame rate seems to slow down when there is a lot going on in the game. What causes this slowdown? Is there any way to prevent it or make it less frequent? solaro 00:33, 14 October 2005 (UTC)
See our framerate article for an overview. The framerate slows down because the game is trying to do more each frame than than hardware can handle in 1/60 of a second (even if it's only taking a little longer than 1/60 second to render a frame, on games that use double buffering the framerate drops all the way to 30 Hz because the next frame won't be displayed until the next vertical synchronization). There are lots of possible bottlenecks — triangle count, rasterization cost, texture memory, sound memory, or just CPU cost. In a console game the most likely bottleneck is triangle count: you can often see this clearly because the framerate drops when the screen shows many objects. On a console there's usually nothing you can do; the developers have decided that it was worth trading lower frame rate for nicer graphics. Gdr 21:58, 16 October 2005 (UTC)
I have been reading about the Royal Society, especially about John Wilkins. Can you tell me about how many fellows there were in the Society in any particular year in the very early part of the 1700's. For example, there might have been a total of deceased and living fellows of 650 in the year 1712. From David F. Grobe, 1207 Bevabeck Dr., Marion, Illinois, USA, 62959
The Royal Society have a searchable online database here although it doesn't exactly provide what you are looking for, as it only seems to be searchable via date of birth and not when they were elected. So there were 862 fellows either alive or dead in 1712 but many of those were still to be elected. They also have all of this data in 26 separate pdf files (yes, seriously!) on their web site, so you could always pull the data out of these if you have too much time on your hands and fancy some slow torture – or you could just contact the Society direct, which would be much less painful and while you're there tell them to put their data in xml format.

A neurologist with experience with this type of brain lesion can give you the best probabilistic answer to your question.

If you have asked this question directly to your daughter's neurologist, you have probably gotten a much more accurate answer than we can give you here.

Could a species, without outside food sources, sustain itself on its own dead? The example I have in mind is cockroaches. ♥purplefeltangel (talk) ♥ (contribs) 05:00, 15 October 2005 (UTC)
Yes. Bacteria are really good at this. Fungi less good but using spores can decrease their need to eat to as close to nothing as you want. Insects can survive a very long time on very little. Snakes (some or all?) can respond to little food by using nearly all their own tissue (and regenerate it later). Imagine a giant meteor hits Earth, kills the dinosaurs, and puts the Earth in a dark winter for decades. Plants die. Everything big dies. Most warm blooded things die. Life forms that eat dead and decayed stuff (the insects) do well. Insect eaters survive. Maybe a few eaters of insect-eaters survive. The exact answer for your question requires a specific species, number of living initially, and lengh of time. Millions of roaches could last centuries I would guess before the last two died. 4.250.198.246 09:55, 15 October 2005 (UTC)
Okay, this is the specific scenario I had in mind: Everything on Earth dies. But the roaches, because they're smart like that, move to another planet. There are no other species on this planet, but there is a light source and there is water. If every roach on Earth was living on this planet and they ate their own dead -- at first killing the weakest, but later on eating those who die of natural causes, wouldn't they be able to sustain themselves indefinitely?

Bear in mind you talking about something potentially illegal here. The publications are copyrighted. This means you purchased ONE copy.

You could physically destroy the original media, and be in compliance in spirit but then if the copyright police find you in possession of the scanned copy, you'd need to prove you destroyed the original, which can be difficult to prove without the destruction evidence.

Nearly all the bacteria are topologically outside our body: on the skin, and in the gastrointestinal tract. Intestinal contents do not acquire a large bacterial component until they reach the colon, but bacteria do represent a substantial fraction of feces (though less than half of the fecal mass). So maybe a kg worth of bacteria in your colon at most, probably less. While we have zillions on our skin and in our mouth, they would probably not add up to more than an ounce (30 g) by themselves. There should be no significant amounts amounts of bacteria anywhere else in your body. alteripse 00:17, 16 October 2005 (UTC)
If you exclude the bacteria on skin and hair, in the mouth,, and in the gut, there should be close to zero bacteria anywhere else inside you. When you are sick, bacteria may proliferate, but even with an abscess full of pus, most of the mass of the pus is necrotic tissue and immune cells and fluid, not bacteria. The bacteria in your colon might be around 1% of your body mass, but those elsewhere probably do not exceed 0.001% of your body mass. You will die long before an infection in your blood produces another kg of bacteria. alteripse 16:43, 16 October 2005 (UTC)

Question : Is metric space with group structure topological group?
Are there any programs out there which can automatically rotate and crop PDFs down to their main body of text? I download a lot of things off of JSTOR for my studies and I like to print them 2 X 2 to a page, but to do so requires first getting rid of the extra page margins on each page (otherwise the text is printed far too small to read). If I could automate this, it would be great, but I can't seem to be able to do it with any of the programs I have (which includes Adobe Acrobat Professional 7.0). Is there anything out there which can do this? It seems like it would be a not-too-difficult feature to make, on the scale of things. I tried using the "Remove White Margins" setting on the "Crop Pages" screen in Acrobat but that does not seem to do anything at all with JSTOR files. --Fastfission 00:44, 16 October 2005 (UTC)
How do electrons stay in their probability field without going anywhere? It can't involve strong nuclear forces (mostly inside the nucleus), weak nuclear forces (too long a distance) or gravity (too weak for the masses involved), so I can only assume that they are kept in check by exchanges of messanger photons. Is this correct?

I recently bought a 15” LG LCD (TFT) monitor. The sharpness and quality of picture in the new TFT-LCD monitor is not as good as my previous monitor, which was a Samsung CRT 15” monitor. I asked about this to the dealer from whom I bought the monitor. He said that even though LCD (TFT) monitors cost more than CRT monitors, both sharpness and picture quality would be better in CRT than LCD (TFT). 1) Is it true? 2) If I should get sharpness and picture quality, what should I do? Is the product faulty?

When is the best time during the day to give a pill to stimulate the thyroid for long-standing hypothyroidism --
There are no pills that stimulate the thyroid. Thyroid stimulating hormone (TSH) is a protein hormone taken as an injection with an effect that lasts about 1-2 days, but whether it stimulates the thyroid to make the right amount of thyroid hormone depends on whether
If your pituitary is making plenty of TSH and it was your thyroid that failed, injections of TSH won't do much good. On the other hand, if your pituitary failed, you could take an injection of TSH every couple of days. There are three drawbacks to using TSH as a treatment for hypothyroidism due to TSH deficiency:
So most doctors treat long-standing hypothyroidism not by trying to stimulate the thyroid gland to work again, but by suggesting the person take a daily pill of thyroxine to provide their needs. Like a vitamin, this can be taken any time of the day, has no side effects at the right dose, and is identical to your body's thyroxine. alteripse 20:16, 16 October 2005 (UTC)
You are correct that it is labeled from the pharmacy to take on an empty stomach because there are foods that bind it and reduce absorption, and there are a few published case reports of people in which the difference of absorption with and without meals was enough to change the dose requirement. Soy is perhaps the most notorious such food for young children. I probably should have agreed with that choice. However, despite this, many people who take it do not pay much attention to whether they take it with food and as long as the TSH levels are satisfactory are getting enough. Sometimes the adherence is enough better if they take it with breakfast every day than if they try to find a time apart from a meal that they get more of it. As far as vitamins and minerals specifically interfering with thyroxine absorption, I am skeptical that they make much difference. If you can cite a paper I would appreciate it. alteripse 20:43, 17 October 2005 (UTC)
Thank you for the references, which appear to support your assertions for at least some people. Perhaps our only difference is how common and how large a magnitude effect this potential interference has. My experience is "uncommon" and "usually minimal or small effect", at least in young people. I will not dispute that it may be more than a trivial effect for some people. alteripse 03:03, 18 October 2005 (UTC)

Greed causes famine. We in the west will give to the poor only when the poor are thrust into our living rooms.People think only of themselves.A few weeks ago mob greed saw a run on the petrol pumps even though there wasn't a shortage. There is never enough petrol to fill every tank in one day but everyone was thinking only of me,me,me. A government that is always mindful of greed amongest its voters will put the third world poor bottom of the list. None of us are going to vote for a government which would give the third world a fair price for it's goods because we would end up paying more. If the good land used to provide us with cheap tea,coffee,tobacco or sugar was given over to grow food for local people much of the hunger in the world would stop. Next time you have a coffee think of the family, mother,father,and kids who spend the day, all day, everyday, just managing to pick enough beans to feed themselves. We are all part of the system which causes famine. --Eye 19:31, 17 October 2005 (UTC)

A roller coaster, of mass 100 kg, is 10 m above the ground at its atarting point, A. It moves down a straight, steep slope of 50 m in length to a point X.
What is the displacement? Is it 10 m or 50 m?
This is my exam question. It asked me to find the velocity of the roller coaster at X, if a frictional force of 20N is acting on it.
How do I find it? My answer was 13.4 m/s (3.s.f). Am I right?
As far as I can see, without known the incline of the slope, this question is unswerable. Perhaps you misread the question? -Lethe | Talk 01:15, 18 October 2005 (UTC)
Aaaaarg! here is the full answer (using the principle of conservation of mechanical energy):
R <--------Roller coaster in t(0), Potential energy: /| 10*100*10 / | Cinetic energy: 50 m / | 10 m 0 / | R----+ ^ (48,something) | Roller coaster at t(1) Potential energy=0 Cinetic energy=10,000 – 20 = 9980
m*v2 100*v2 E=--- -> 9980=----- -> v2=199,6 -> v=14,13 2 2
So, the speed ~14.13, and the displacemente is 50 m. Note: probably your teacher made an error, the problem doesn't make sense with 20N, but it does with 200N. --User:Mdob | Talk 23:12, 18 October 2005 (UTC)
Thats not right, frictional force is acting alone the plane, so the displacement is 50 m, that is the distance the coaster travels, and all anong that way friction tends to stop it with a constant force of 20N. Force is N=kgm/sec^2 energy is Kgm^2/sec^2. The energy spent is going down is mgh=100*9.81*10=9810J the energy spent on friction is Fd=20*50=1000J The final energy is going to be all Kenetic, and is 9810J-1000J=8810J this is 1/2*m*v^2 Solving for v v^2=2E/m=2*8810/100=176.2 We get displacement of 50m v=~13.3m/s I enjoy kinematics.

I was wondering... on average how much a year does a volcanologist get paid? Also, how long do you typically have to go to college for if you are going to work for the USGS?
Thank you. April
April asked the question earlier, but we didn't give her an answer on the pay. April, follow the link in my last sentence for answers about how long you need to go to college for.
The pay varies according to experience. I can't answer for the USGS, but I tried two Google searches: vulcanologist salary and volcanologist salary. From these, it appears that pay ranges between US$30,000 and US$100,000. If you look at these searches yourself, please check what the currency being referred to is – not all positions are in US dollars.
The USGS does give a table of salaries here, but I can't find anything which explains what grade range a volcanologist may be in. This site will only help if someone can find an explanation of grades for scientists.-gadfium 03:03, 18 October 2005 (UTC)
I want to display a tree on the web. I did a similar project many years ago when I was a student where I displayed a binary tree in Java. But I'd rather something more native to web browsers. I have a LAMP (apache with php and mysql database on gnu/linux) set up, and I want to dynamically display portions of data stored as a tree (not necessarily binary). What's the best way to render this? I thought maybe CSS. Does CSS have the ability to layout things precisely enough to make a tree? I've never used CSS, so I'm not sure what it's capable of. So can it like, have an outlined box with a picture, some text and hyperlinks in it, and place it according to coordinates that I would calculate, then draw lines connecting various such boxes in a tree shape? The coordinates and slopes and placements of lines would all be calculated in php. So what do you think? thanks -Lethe | Talk 21:01, 17 October 2005 (UTC)

I believe the original poster it trying to create diagrams like this: File:6n-graf.png. If you want, you could use CSS to position the boxes: just put each of them in a div, and give it a style attribute like so:
<div style="position: absolute; top: 123px, left: 456px; border: 1px solid black;">graph item</div>
Unfortunately, to the best of my knowledge CSS has no way of drawing diagonal lines, circles or other advanced shapes. Since you already have PHP set up, you might want to try using the GD library (http://us2.php.net/gd) to construct the diagram as an image. Another alternative would be SVG, but that currently requires a browser plugin. --David Wahler (talk) 15:09, 18 October 2005 (UTC)

is consumed some of it actually penetrates the tounge and enters the bloodstream that way. Other drugs do not do that, at least to that extent. It also does not need to be digested to enter the blodstream and can be used as food, sort of. There is a story that certian types of diabetics can take in alcohol in an emergency to keep them alive until help arrives. I do not know how true that story is, though. Read it years ago in readers digest.
Read about receptors. Most drugs have actions on specific organs because their recptor-mediated actions are generated only in certain parts of the body. Alcohol has effects on cells that are independent of a specific receptor, allowing it to have effects on all cells. The chemical nature of alcohol that gives it the ability to penetrate to all tissues (see above) is also important. --JWSchmidt 14:01, 18 October 2005 (UTC)

Okay, since the Peanut Gallery answered my spoiled hamburger question so well, hopefully I can get some equally good advice about my laptop...I have an old (2001 era) Gateway laptop as my backup computer. The fan has died, and for a while it worked OK, so I took it to my brother, a semi-pro electronics wiz to repair. However, as the fan is very hard to come by, he can't fix it. Now, it overheats and goes into safe mode in about a minute. Next week I am going on vacation, and will be taking my Fuji S3100 camera with me. I have one 256 Mb xD memory card, and the idea was that I would use the computer for a few miuntes a day to dump the photos. But now, I can't even do that, as it wont stay on long enough to copy the files. So, I had an idea: What if I keep the laptop in the refrigerator to keep it cold? I know thatthis is not usually a good idea, and that condensation is going to be a problem, but frankly I want to take a lot of pictures more than I want to keep the dying laptop. So, will this work as a way to keep it running for a few more days? I won't need it more than 15 minutes a day, for 7 days. Any ideas? Brian Schlosser42 19:25, 18 October 2005 (UTC)
A friend and I have had an ongoing dicussion regarding what happens when someone fires a bullet straight up. As the physic laws state, in a vacuum the speed of the bullet, which is 300 m/s using a common handgun), as it comes down would be the same as when it left the chamber (Parabolic shot). So it would go fast enough to kill someone. However, I believe that because of the small mass and friction with the air the bullet would slow down so much that it is mostly harmless.

Life exists many places on our planet where we humans cannot, although perhaps not sentient life.
Consider a system with 2 or more stars orbiting each other, or a black hole, or whatever, there's enough radiation there for planets to be further away and sustain life.
Our moon is humogous relative to our planet by average standards, so we evolved with significant tides, very rare as averages in our known universe goes, although telescopes not yet telling us a whole lot about planets around other stars. How come our moon is so large? Well I buy the arguement that once upon a time there was a planet between Mars and Jupiter that broke apart, and a lot of the pieces did not stay where the asteroid belt now is, they flew outwards and inwards, and some were captured by gravity of other planets, one of which being our moon. I recognize that is not the most popular theory of astronomy.
Meteors have been found with fossils inside. How did they get there? Most plausible to me is that when our planet was hit with a really large rock from space that made a crater like Hudson's Bay in Canada, the rock that killed off the dinosaurs, etc. that some of our planet splashed into space, and those chunks of rock had life that became fossilized, but there is an argument, that I cannot follow, that says some of that came from Mars. Assuming these rocks carry simple life that can come off them and thrive again, when given moisture and light, then contamination can travel from planet to planet.

Throughout my entire life, I had a problem with "thinking". I always thought way too much about things, all sorts. I can't control it at all, and in several occasions I got headaches and sick because of it. It's physically PAINFUL sometimes (I get tense and my throat, face, neck and guts hurt). I've tried learning relaxation techniques and all, seen psychologists, and even got to a few doctors who offered me some medication (fluoxetine). It didn't work. Recently I had an issue with a friend, partially because of this. I, of course, am feeling terrible about it. The problem is, this led to a major impulse in this thinking pace, and I can barely sleep now. I'm hardly hungry (but I got more thirsty for some reason). And this all scares me. I'm beginning to think there's something neurological behind this. So I set an appointment with a neurologist. I'm not sure if this is the best thing to do, but can't be any harm, eh?
My question is this: are there any sort of neurological conditions that cause this sort of problems? If so, what sort of medical solutions can be taken? If not, what could I possibly do, I've ran out of ideas here.
The symptoms you describe could means lots of things, including a little bit too much anxiety and self-analysis. None of us have any business diagnosing you with anything definite. However, I will offer guidance to the right kind of doctor. Your symptoms undoubtedly fall on the mind side of the old cartesian mind:brain divide. Whether you need reassurance and insight, constructive suggestions, or diagnosis and treatment, you will get more help, more sympathy for the symptoms, and a more experienced perspective from a mind doctor than a brain doctor. I promise I am saving you a step. Good luck. alteripse 23:09, 19 October 2005 (UTC)
I would be careful. I was diagnosed with OCD and put on medication. Nothing worked. I had 4 different kinds over 4 years. By then I was a wreck. Finally I found out I did not have OCD. It has taken me years to recover. If the problem is just thinking, then that is not really a problem. If the problem is thinking about the same things over and over without any resolution, that is an anxiety disorder. You are probably very smart and like to think about things, like quantum physics. Arguing with yourself might just be a very pronounced way of resolving inner issues, trying to make decisions. Alteripse is right, though, when saying none of us has any business diagnosing you by 'remote control' this way. Find a good counsellor and get some help, it may be you just have an active imagination. Top priority is to find a counsellor you trust.
I have a similar problem, though nowhere near as serious. I just can't get to sleep because I'm constantly thinking of things. A 'solution' that has worked for me for 25 years is to smoke some marijuana before sleeping. Just a bit works wonders. A big advantage is that if it doesn't help it won't hurt any either. A potential major problem is that it can land you in prison in many countries (I have the good fortune to live in the Netherlands). Although even in the US it's accepted as a legal drug these days, I believe. You'd just need a doctor to prescribe it to you. DirkvdM 15:07, 24 October 2005 (UTC)

I have a few questions about hybrid vehicles like Toyota Prius. What I want to know is- 1) How much more hybrid vehicles like Prius cost (in %) more than gasoline powered vehicles with similar power and capacity? 2) How many times mileage does Prius or other hybrid vehicles give compared to similar gasoline vehicles? 3) Should we charge the battery that runs the car similar to electric cars? 4) Are all hybrid vehicles automatic geared?
The matrix is significantly larger than the Prius, the Prius is more similar in size to the Echo. A better comparison would be the Honda Civic ($14,650) vs. the Honda Civic Hybrid ($21,850), that's a 50% difference in price and averages 15mpg better. That means at 10000 miles/year and gas at $3/gal, The Civic would use 285 gallons of gas a year and the Hybrid would use 200 gallons of gas a year. That means you save a whopping $255 a year, which means you would have to own the hybrid for over 28 YEARS for you to come out ahead. Despite the manufacturer's marketting, Hybrids are still nowhere CLOSE to economically feasible.

Hello, I hope you can help with this enquiry, I am currently on a medical course and have just failed a practical assesment. I was following the protocol as I understood it in that I shocked my PVT patient four times until their rhythm changed. What I saw was a sinus rhythm and checked the carotid pulse and was told that there was a weak palpable pulse. I interprited this as sinus rhythm and gave AV for one minute and re analysed patient. On completion I was told that the patient had been in PEA and should have commenced CPR. Am I way off the mark or can you as was explained to me by the assessor a palpable carotid pulse in PEA?

Many years ago I remember my maths teacher saying that mathematicians didnt use infinity in equations. Something to do with things not adding up. I was never interested in maths but that has always stuck in my head. Is this true? If it is true how then does science deal with infinity when the language of science is maths and infinity in terms of the universe is ..well .a distinct possibility.--Eye 22:12, 19 October 2005 (UTC)
Mathematicians definitely do use infinity, although for reasons the above posters mention, you must use care, or you'll end up in trouble. There are in fact several different numbers which could be called infinity. There is the infinity in the extended real line, which satsifies a bunch of things like infinity + any number = infinity. The expression infinity*0 is left undefined (no one claims that infinity*0=5). Other infinities include omega and aleph nought, and many more. -Lethe | Talk 01:06, 20 October 2005 (UTC)
Of course any discussion of infinity (you have at least skimmed that article right?) would be lacking without a mention of cardinality of infinity. That is something that blows most peoples minds when they first learn of it because they are used to the conventional wisdom of infinity being the biggest thing out there. How could there possibly be different sizes of infinity? Well at least in set theory there is. - Taxman Talk 18:17, 20 October 2005 (UTC)
I think you people are deliberately trying to confuse me. :-) --Eye 20:14, 20 October 2005 (UTC)
If then one might assume that the infinity being referred to is countable. However, if one accepts the existence of countable infinity, then by set theory (see Cantor's diagonal argument), one must also accept the existence of uncountable infinity. If the reciprocal of countable infinity is zero, then surely the reciprocal of uncountable infinity is also zero? Of course. But then what is the reciprocal of zero? Is it countable or uncountable? It cannot be both, because if 1/0 is equal to both infinities, then the two infinites are equal to each other, which they are not, by definition. So paradoxes such as these blow up in one's face, and one must conclude that infinity is somewhat beyond ordinary grasp.
It depends on what field of numbers one is dealing with. The field of real numbers does not include infinity even though its cardinality is uncountable infinity. So when one asks "how many real numbers are there?" the answer is not a real number. Real numbers are good enough for practical purposes: infinities being dealt with as limits. However, it is possible to define other mathematical structures which include things which are called "infinities". For arithmetic, see surreal numbers. For geometry, see projective geometry.
Physics is based on the ability to take measurements of physical quantities, such as mass, distance, and time. When an experimental physicist makes a measurement, the instrument which makes the measurement is finite, and the number resulting from that measurement is finite. Physical theories are confirmed by being tied down to experiment (see empiricism) and physical experiments always give finite answers. Physics deals with infinities by getting rid of them, by hook or by crook: see regularization and renormalization.
Mathematics, on the other hand, is rationalistic and not empirical. Mathematical structures are tested by self-consistency: if it is not self-consistent, it does not exist. Each mathematical structure is self-contained and independent of other structures, so Euclidean geometry and Riemannian geometry each have their own separate existences, even though they would contradict each other. (Likewise, the theory of infinity has two branches, one which accepts the continuum hypothesis, another which rejects it: but each branch capable of being self-consistent.) Moreover, mathematical structures do not have physical existence. The number five does not physically exist. One might have five finger's on one's hand, but the five fingers are not the number five. One might draw a red number 5 on a paper, but that five is not the concept of number five. The symbol for infinity is not itself infinite. The symbols which mathematicians manipulate on paper are all finite. Infinites are known only indirectly, through logical inference, and inhabit a non-physical realm. So when one says "There are a countable infinity of natural numbers", those numbers do not really exist physically. Besides, if mathematics only dealt with infinities, it would be impractical and rather useless and mathematicians would not gain their bread, whose quantity is finite, positive, and non-zero, which they eat regularly in order to obtain a finite, positive, non-zero amount of energy (see pragmatism). On the other hand, mathematics does have a corner of its realm permanently reserved for infinities: as Hilbert said: "No one can drive us from the heaven which Cantor created for us." —Anonymous, 20 October 2005
I'd like to know just how skilled one would have to be at mathematics in order to go into the field of computer science. After reading some articles on the subject here on Wikpedia (which I could barely understand, if at all) it seems like a fascinating field. Impaciente 01:09, 20 October 2005 (UTC)
Computer science is broken into several branches, including computer engineering/architecture which requires some technical skills to learn what component functions are, computer programming, which is oriented towards learning languages and a form of qualitative logic that is needed to understand the workings of the code of the program, and then, computer networking and information technology, which is concerned with computer services and networks. In computer programming, generally very little math is required, but that is only in my experience. Pick out books or articles about certain regions of comp-sci and find your way through the subject.--Screwball23 02:02, 20 October 2005 (UTC)
My experience has been that computer science doesn't require a complex mathematical background. In completing my Bachelor's degree, I would have only encountered complicated mathematical formulas once or twice (in case you are wondering, Data Communications and a subject on Artificial Intelligence). Apart from these two instances, I think a sound knowledge of algebra and problem solving will probably get you through (bear in mind I am Australian, so maybe your education system is a bit different). Ranglin 02:56, 20 October 2005 (UTC)
I'm an application programmer speciallizing in CAD and database apps. While I have used advanced math up to calculus in some of the applications (calculating component masses for center of gravity analysis), this is just my case, not typical. I would say a typically programmer won't have to deal with more than basic math, perhaps time math and percentages being the limit (used for benchmarking how much faster one version of a program is than another). Knowing how to extrapolate a graph is also quite useful..."If the program can process 10 items in one second and 100 items in ten seconds, it should take how long to process 1000 items ?". If you work with graphics, some knowledge of geometry is also needed, such as the formulae for distance and a circle. StuRat 22:22, 21 October 2005 (UTC)

Hello, all. I have a question/favor to ask. This question may be in a wrong column for asking, but here it is. Long time ago, I saw in a newspaper with a columnist showing and explaining just how much a trillion dollar is, in a sense of talking about national debt, and to make it easier for everyday folks to understand, there was a breakdown of a trillion dollars on this column. A broad general example would be that a trillion dollars is enough money to buy 30 NFL football stadiums, 100 3-carat diamond rings, 100 Corvettes, and still have a lot of money to buy or do other things. For some reason, a columnist's name Dave Barry comes to mind. I may be totally wrong on who this columnist was back then, but if anyone out there has any positive feedback or information or the article on it, I would really appreciate the information. Thanks.

Which body parts are considered sexual arousing on sight is purely cultural. In our own society there was a time when the sight of a woman's ankles was considered sexual, so such people might well have asked us "how can you still be interested in your wife if you see strange women's ankles all day long ?". There are many societies where breasts are exposed, and a few where full nudity is practiced. In such societies, the sight of those things lose their sexual allure.

Imagine I invented a machine that could morph something say like a rhino into a banana. I put the rhino in at one end and a banana comes out at the other end. (Yes it would be a big banana). Anyway imagine that I could watch the process and this process could be viewed in ratio terms. The change would first be 99 rhino and 1 banana then 98/2 and so on. As I watched the process I would have to decide whether or not the thing I was viewing was either a rhino or a banana as it clearly could not be both. It is either one or the other. When the rhino gets down to 51/49 it is still a rhino and not a banana. A point will arise where in order to complete the process of change the morphing rhino will have to leap the divide of the 50/50 point to become a banana. I say leap because it could not be possible to exist as two things at the same time It could not exist on the 50/50 point. To one side of the 50/50 it is a rhino, to the other side of 50/50 it is a banana. If infinity exists then the process would never cross the 50/50 point because the process would be infinitely dividing down towards the 50/50 point but never quite reach it… or as it came close to the 50/50 point the process would stall … until enough pressure for change had built up to cause it to leap the divide. Would the rhino suddenly change into a banana or gradually change? Is this a fair analogy of say, changing systems in nature, where evolution stays the same for donkeys years and then suddenly there is a big change. Or physics where an atom can absorb so much energy before suddenly jumping up to a higher energy level. Or say global warming, will our earths weather system under go a sudden change if enough pressure builds up? How close could we be to that change? Will I ever stop asking questions? :-) --Eye 20:24, 20 October 2005 (UTC).
IMHO, this is not a fair analogy, no conclusive proof has been offered for global warming, and the notion is unfortunatly unable to be determined given the political climate. In many places things have been getting hotter, and in some colder. Superimposed on this is the warming and cooling that occurs over centuries.

An infinite series of times can actually add up to something non-infinite. Say you're doing the last percent, and you're "infinitely dividing it" – so 51%, 50.5%, 50.25%, 50.125%..... But, you need to remember you're also dividing up the time needed to perform the task. Also, pretend you have a super-camera that takes a picture every time you "divide it". If the process takes, for example, 100 seconds, you're taking "snapshots" at 49 seconds, 49.5, 49.75, 49.875..... You might be taking an infinite number of "snapshots" (and you can assemble them into an infinitly long movie), but your snapshots don't slow down time! Also, the first half of a percent takes half a second, then the next quarter takes a quarter of a second, then the next eighth takes an eighth....and it all adds up so that the last 1 percent takes 1 second. There's no paradox at all. AySz88^-^ 20:52, 20 October 2005 (UTC)

Regarding the comparison with evolution, I don't believe evolution ever moves "instantly" from one species to another, but do believe it moves quicker at times and slower at other times. We might choose to classify one individual as one species and it's offspring as another, but that is just due to the way we classify things, there wasn't necessarily a large jump between the two individuals. I would say periods of rapid evolution happen due to changes in environment (including the food supply and predators) and enabling changes in the species itself. In primates, for example, the opposable thumb originally evolved as a way to hold onto tree branches, but enabled tool use as well. This led to a rapid evolution of intelligence in primates to make use of this capability. StuRat 21:33, 21 October 2005 (UTC)
Not sure if this is helpful, but there are exampels of natural systems that suddenly switch mode. Transition of fluid flow from laminar flow to turbulent flow is one. As you increase the speed of water flow, the pattern doesn't change much. Then, over a very short range of speed it suddenly switches from one pattern to another. Above that the pattern stays relatively constant in the new pattern. The same could (could) easily apply to cilmate change. DJ Clayworth 20:40, 25 October 2005 (UTC)

I have noticed that if a strong red and a turquoise or blue-gray border on one another, I find it very difficult to look at. It's not a kind of colour-blindness, because I can clearly see the difference between the two; actually, it's more like the contrast is too great to see properly. The border appears to sort of crawl and it is unpleasant to focus on. If I see these two colours bordering one another even in my periphery it is distracting, almost as if something is blinking or moving in my periphery. Does anyone know what this is? Is it common? Bryanmtmorrison 21:01, 20 October 2005 (UTC)
While the area we focus on sees the most detail, the periphery is good at detecting movement. In your case it sounds like the "threshold" for seeing movement is too low, and you eyes/brain detects movement that isn't really there. StuRat 21:19, 21 October 2005 (UTC)

Why can't you trap light in a mirrored (on the inside) box? When I first asked my dad this, he told me that if you cut off the source of the light when shutting the lid, the wave can't exist inside the box. This doesn't satisfy me, however, because light can still travel through space, and, indeed, be bounced off mirrors, after a star has died.
Say light is coming from a distant star. I bounce it off one mirror and set up another mirror far away parallel to it. Would it keep bouncing between them? The energy decreases rapidly with distance because it all disperses, sure, but the same would not be the case in an enclosed-on-all-sides box.
I'm guessing that it's because the mirrors absorb energy with each bounce and that, in the tenth of a second it takes me to close the box and open it again, the light has bounced around a zillion times and lost all its energy. Is that right? And would it be theoretically possible to have a perfect mirror in which this energy loss (if that's what it is) didn't occur?

can the energy (electricity) in lightning be saved or stored? why, how or why not?
mckeancharles@(email removed)
The problem is that lightning is so irregular that collecting it would require millions of lightning rods all over the collection area. The strength of each bolt is quite different, too, so you would need to be able to handle the maximum case to prevent your equipment from getting fried. Then you would need an efficient way to store the energy until needed. The cost of all this far exceeds the benefit, at least at the currrent cost of electricity. Perhaps some future technology, like balloons carrying thin metal fibers, can make it profitable. StuRat 21:09, 21 October 2005 (UTC)

If 84% of sea water is evaporated every day, why isn't water salty? Please have the answer in soon. Contact my email: (removed)
The atmosphere has water in it, some of which falls to earth (rain, snow, etc), and every day some of the water on the Earth evaporates back into the atmoshere. Around 84% of the water that evaporates back into the sky evaporates from the oceans, but is replaced by the water that returns to the oceans (rain, snow, rivers, etc.) so the water content does not change day to day (but does change century to century).

I need to write an essay on Toothpaste, its history, the devolopment procedures of toothpaste (including any equations or formuals and why it was made) and any benifits to this compound. I also have to write the same information about charcoal and how it can be used as toothpaste and i need to write the positives and negatives side of using toothpaste instead of charcoal. As you can tell, I'm having no difficulties finding information about the toothpaste side, but i am finding it extremley hard to find some information abut the charcoal side. Any information about charcoal and toothpaste would be of great use to me.
Thank you
Thank you for your reply, but i am still in need for more information about charcoal. I have already looked up the sites that you advise me too see and managed to find some information about toothpaste but not charcoal. Again thankyou for your help and any information about charcoal would be of great use to me.
I guess they don't. An animal that snores would always attract predators or alert preys. Such a genetical feature shall be eliminated by natural selection in no time.
I also don't think ancient humans and earlier hominids snored much. I guess snoring marks the rise of our undefeatable human civilization where men in bed are no longer eaten by big cats. As a result, bad genes are not eliminated and people start to snore. -- Toytoy 10:08, 22 October 2005 (UTC)
Q. Do any animals besides people snore?
A. Yes, some animals do snore, according to anecdotal reports and personal observations, said Penny Calk, manager of the mammal collections of the Bronx Zoo.
"Some that we have observed are dogs, gorillas and bears," she said.
The mechanism of snoring in these mammals probably resembles what happens in people. In human beings, according to The American Medical Association Encyclopedia of Medicine (Random House), snoring is noisy breathing through the open mouth produced by vibration of the soft palate, the back part of the separation between the oral and nasal cavities. It is more common while people are sleeping on the back, as the lower jaw tends to drop open. Snoring is caused by anything that hinders breathing through the nose. Gnats
Dogs of different breed can be very different from each other. How does a Dalmatian recognize a Chihuahua?
Humans are not dogs. How does a dog recognize humans? A person can wear a red T-shirt today, a black tuxedo tomorrow. How does a dog (color blind) learn to disregard some but not all visual signals? How many house pets can recognize their owners if the clothing, smell (perfune) and facial features (shaved or not; hair cut; cosmetic makeup; eye glasses) changes? Can a guinea pig does that? Can David Prowse's dog recognize him if he wears the Darth Vader suit? -- Toytoy 10:53, 22 October 2005 (UTC)
I heard some where that a dog can recognise more smells than we can recognise colours, for example, if two colours of red were so close we couldn't tell the difference, if those reds were smells, a dog could tell the difference.--Eye 19:23, 22 October 2005 (UTC)

Does anyone know what it's called when saliva sprays from underneath your tongue toward the back of your mouth? I've never heard of this spoken of, but have experienced it, as has at least one other member of my family. Theshibboleth 16:29, 22 October 2005 (UTC)
To my knowledge, there is no formal word to designate the forceful ejection of saliva from under the tongue (I cannot exclude the possibility that a slang word exists). The phenomenon results from the compression of the ducts of the sublingual and the submandibular salivary glands by the muscles of the floor of the mouth, such as the mylohyoid, the digastric and the genioglossus, which cause a rapid expulsion of the ductal contents. By the way, the saliva is usually projected forward and upward, rather than toward the back of the mouth. I have been sprayed by my patients in this way on several occasions...

For years, I've been told that nicotine can stunt the body's growth. Is this a fact? Thanks, Dave.
Cigarette smoking can stunt your growth if your mother does it, before or after you are born. The evidence for mild prenatal stunting is strong, the evidence for postnatal (i.e., secondhand smoke effects) weaker. Unless you are idiot enough to turn mild asthma into severe by heavy smoking in early teens, your own smoking won't affect the last couple of years of remaining growth. Although most smokers start as children, most of the adverse systemic effects that might interfere with growth take several years to accumulate.alteripse 04:30, 23 October 2005 (UTC)

To make an unfair coin fair, one can use the following trick
If a coin is bias then it cannot be used as a fair coin. But if the rules of the game is changed to properly rely on when the coin gives a certain result, the coin can still be used to produce a fair result. John von Neumann gave the following procedure :
1. Toss the coin twice. Note down the first "result" and the second "result". 2. If the results match, start over, forgetting both results. 3. If the results differ, use the first result, forgetting the second.
Note: This procedure only works if the tosses are paired properly. If part of a pair is reused in another pair, the fairness may be ruined.
My question is this:

I need some information on the concerns regarding the effect GFP tags have on the behaviour of proteins, but searching for "concerns" "GFP-tagged protein" on Pubmed and Clusty only gets me experiments and papers where they were used.
Has anyone got an idea on how to refine my search, or can someone point me to a good resource on the subject. I've got the basic issues down, but I'd like to be more thourough. - 131.211.210.17 09:27, 24 October 2005 (UTC)
Don't use "concerns" in a scientific literature search. It is a reflection of your state of mind or valuation of something but the gap between denotative meaning and common connotative usage is too large to be a useful coding term. If you are concerned about actual risks, then search for "risk" as a term. If your concern is whether use distorts the function it is being used to measure, search for a general review of GFPs and scan for one from a methodology journal, and you should find a discussion of the issue. If neither of those is your "concern", I can't even guess and you will need to spell it out more plainly for us. alteripse 11:32, 24 October 2005 (UTC)
I don't know much about this particular method but would start by looking for some review articles about the method itself to see if there is a discussion of your question, which now makes sense to me: If you tag a protein to observe it, does that change the behavior of the protein in an important way? Sounds like a good question. I assume that early work on the method compared the results obtained by GFP tagging with results obtained by other methods. Have you looked at any of the more recent volumes of Methods in Enzymology if you can't find anything online? As a last resort, call or email someone who has written one of the reviews and ask if they know of any examples in which the method gave misleading results because the tagging interfered with the protein. alteripse 20:59, 24 October 2005 (UTC)

First thanks for answering my earlier question on sun & planets gear & epicyclic gearing. This one is rather more theoretical. Is there at present any sort of semi-permeable material which would allow specific gasses (such as CO2 & Ozone) through into a balloon or other container but not let them out again. Would it be able to do this at normal pressure & therefore collect CO2 directly from the atmosphere, through some sort of osmosis or would some sort of pump be required to pump in air to the balloon & pump out all the air less the CO2. My reason for asking is that I had the thought of collecting CO2 in massive dirigibles/balloons & towing them to Mars to start off an atmosphere there. I also thought of taking gasses such as Ozone from a gas giant such as Neptune & towing them to earth to fill the hole over Antartica. I know we don't have the rocketry technology to do this right now but can we do the gas capture with current (or expected) technology? AllanHainey 13:56, 24 October 2005 (UTC)
In the first book of Star Trek: The Lost Era, a weapon called a "monomolecular blade" is described. It's a knife or sword whose blade is only one molecule thick. It is described as being able to cut through practically anything – cloth, skin, bone, even solid steel – as if it were cutting through hot butter. Would this work in real life, and if so, why? — JIP | Talk 16:22, 24 October 2005 (UTC)
If it is one molecule wide and many thick, you would find that in the diction of cutting it may be stiff, but the lateral stiffness of a sheet one molecule thick may be lacking, IMHO. Carbon nanotubes are not one molecule thick. As I recall, bayonets with serrations were especially deadly, to the point that during WWI if you were captured with one, you usually were going to die of your wounds, past or future. Clean cuts are not always as deadly. Dominick (ŤαĿĶ) 20:03, 24 October 2005 (UTC)

How fast does the earth spin around the sun? Name:Aidan Age:8
The earth circles the sun once a year, traveling at a velocity of roughly 27 000 000 000 000 000 000 000 miles per year, or about 74 000 000 000 000 000 000 miles a day, or about 3 000 000 000 000 000 000 miles an hour.

OK, probably I shouldnt have done off the top of my head math. I was remembering 24,000 mi circumference, 93 million miles to sun (=radius of orbit), and pi r squared for the diameter of the orbit travelled in a year. Where did I make my mistake? I see, I think I used too many zeroes and squared 93 trillion rather than million, and the diameter is pi x r not pi r squared. That would do it, wouldnt it? 93 million x pi would be 292 million mi for orbital diameter in one year, or 800 000 mi per day, or 33 333 mi per hour. Now I agree within a factor of 2.

Where do the seeds go in seedless fruits, or, how do these fruits become seedless?(some grapes, watermelons,oranges etc.) Are there different methods or reasons for this? If so, what are they? Thanks! Hattie
While the original bananas contained rather large seeds, seedless and triploid varieties have been selected for human consumption. These are propagated asexually from offshoots of the plant. The plant is allowed to produce 2 shoots at a time – a larger one for fruiting immeditely and a smaller 'sucker' or 'follower' that will produce fruit in 6 – 8 months time. The life of a banana plantation is 25 years or longer, during which time the individual stools or planting sites may move slightly from their original positions as lateral rhizome formation dictates.

how would the tablet(MOM) respond to the actual stomach when the stomach continues to secrete acid?If you could please reply.. thanks.
The active ingredient of MOM is magnesium hydroxide. It reacts with hydrochloric acid to produce MgCl2 which is colorless. If you see a color change it might indicate that your brand of MOM tablet has a stabilizer or sweetener or additional ingredient in the tablet that is reacting with the HCl. Read the fine print on the package of tablets, or try a different brand of MOM.

What are the Main Focal points when detemining Input/Output (I/O) data of a client?
You'll have to figure out what a "main focal point" is; it sounds like nursing jargon with which I'm not familiar (sorry), and infer from context whether "input" and "output" are referring to process or to fluid balance sheets, but assuming your question refers to fluid balance, when charting inputs and outputs, the following are some of the main considerations:
In general, charted inputs and outputs are quite inaccurate and must be supplemented by daily weights when the information is actually needed. In a healthy adult, output is 62% urine, 19% via skin, 13% via lungs and 6% in feces. - Nunh-huh 03:19, 27 October 2005 (UTC)
How do anabolic steroids work? How do they effect the cells and muscles of the human body?
Anabolic steroids are a type of steroid hormone. They pass through the outer membranes of many types of cells, interact with a cytoplasmic receptor for androgens and perhaps other receptors as well. The bound steroid-receptor complex moves into the nucleus of the cell, where it binds on certain target areas of the chromosomes, where it alters transcription of certain DNA sequences called genes. Activation of certain genes and inactivation of others results in a variety of changes of cell metabolism. Many of these changes involve increased rates of synthesis of various structural proteins such as those in cartilage and bone, certain functional proteins such as those in muscle, and certain protein hormones such as growth hormones. The net result is a stimulation of processes we call anabolic and a slowing of many processes we call catabolic. The anabolic processes tend to induce growth and enlargement of sensitive tissues and organs, or increases in density or strength. Does that answer your question? alteripse 04:12, 27 October 2005 (UTC)

sir,
i would like to know about the chemical responsible for increase in RBC count after taking hygrophila spinosa preparation ,a medicinal plant which is semi aquatic.i would like to know whether the main component has been seperated yet or not.
thanking you
The only research paper indexed in pub med is PMID 11491586. This rat study from India found evidence of ability to raise the RBC count, but did not identify the specific substance responsible. I would infer from the wording of the abstract that as of 2001 the substance had not been identified. It also seems likely from the absence of follow-up papers since 2001 that the "haematinic effect" has not been reproducible in people, but I might be wrong of course and some major drug company may be in the secretive phase of investigating a potentially profitable protein. alteripse 11:46, 27 October 2005 (UTC)

Dear Sirs,
Your web-site mentions 2 definition of mean curvature for e.g. a 2-surface embedded in 3-space i.e.
H = (k_1 + k_2)/2 the average of the principal curvatures k_1 and k_2
but also, to within a constant:
H = div (n) where n = grad f/|grad f| for a hypersurface defined by f(x_1,x_2...x_n) = 0
My question
How do you establish the equivalence between these two formula?
A reference would be appreciated!
Thanks in advance

How much space does it take on a PC to store one bit of information? -EnSamulili 08:45, 27 October 2005 (UTC)
Assuming that you are asking about a minimal representation, then an old text editor program like edlin consumes 12.3 KBytes. The typical block size for a current PC is 1/2 to 1 KByte. Thus the minimal size for a file will be 1/2 KByte. So the overhead consumed to store that one bit of information would be 12.8 KBytes. In the old days of computing this was a real consideration. Today 1 bit on a 1GByte PC would cost less than a billionth of the cost of that PC and can be neglected for all practical purposes, when a 100GByte external drive is a commodity item these days.

A canadian website lists active ingredient LD50 = 3mg/kg (a dose that kills 50% of people) at about 10 mushrooms. You can get to a lethal dose with less, much less. Eating half the LD50, doesn't mean you are safe, like any poison, only none is safe, you can still get sick go into a coma or have fatal convulsions. This amount of active poison will vary wildly with the mushroom growth and season. Only use the fly-agaric to kill flies. It is not a good choice for recreation.
It is a simple error to mistake other species for this species. [72] Do not try eating these mushrooms, if you screw up you are screwed.

This came up at my conscientious objector place. We know that if there is a group of over 365 people, at least two people will have the same birthday. But if we pose the question "backwards", i.e. how large a group of people has to be so that every day of the year is a birthday of someone? The correct answer, of course, is "infinite", as there is nothing preventing, for example, everyone from being born on the same day.
But given the number of people, what is the probability of every day in the year being someone's birthday? For 1 to 364 people, it is 0, i.e. such a thing is impossible. For exactly 365 people, it is 1/(365!), i.e. 1 divided by the factorial of 365. But what is the probability for larger groups?

Yes, it has security and bug issues, but it's a heck of a lot easier for the layman to use than Linux or whatever. Ditto IE. Linux doesn't have as many problems because a) a lot less people use it, and b) The people that do use it are technically adept. If the same number of users (and with that, the same level (or lack of) technical knowledge) had Firefox and Linux as do those with IE and Windows, then I dare say there'd be just as many problems with those two programs.

Why doesn't hair gray uniformly. That is, why do sideburns tend to gray before the hair on the top of the head, instead of uniformly (randomly) all over the head. Are those hair follicles different? --Quasipalm 21:07, 27 October 2005 (UTC)
You are correct: there are differences between hair follicles and surrounding skin cells and growth signals in different parts of the body. Why doesn't hair grow uniformly on all areas of the body? Why isn't hair on all parts of the body equally sensitive to androgens? The answer to the first question (about growth) is likely to involve many different factors, while the answer to the second (about androgen sensitivity) is likely to invole only a couple, but both are examples of bodywide differences in hair growth. My hunch is that graying is more like the limited number of factors influencing androgen sensitivity but we don't know what they are as well. alteripse 10:07, 28 October 2005 (UTC)

What is the chemical formula of lipofuscin and is it the same chemical involved in dementia and age spots.
If known what causes its production?
Richard
Lipofuscin can accumulate in many cell types but I do not think it is specifically associated with age spots; they seem to be due to uneven distribution of melanin. Some neurodegenerative disorders have been associated with lipofuscin accumulation. Lipofuscin is not a single chemical; here is a more detailed article about a major retinal lipofuscin associated with macular degeneration: Biosynthesis of a major lipofuscin fluorophore in mice and humans with ABCR-mediated retinal and macular degeneration. There have been attempts to find associations between Alzheimer's disease and lipofuscin, but I don't think links have been demonstrated. --JWSchmidt 04:53, 28 October 2005 (UTC)

I don't understand what you mean by positive reaction: a detectable effect of building white blood cells or a detectable beneficial effect of building white blood cells?

Are you asking if it is beneficial to increase the number of WBCs?
You are aware that too few WBCs are bad and too many WBCs are bad? That making more if you have too many is not necessarily beneficial? That there is no demonstrable advantage to having a WBC count of 9,000 per mm3 instead of 8,000 in a healthy person? alteripse 03:20, 28 October 2005 (UTC)
What does "recement" mean? It is in benefits lists for dental insurance, and used in the context of "recement crown", "recement inlay" or "recement cast".
--64.174.7.191 03:16, 28 October 2005 (UTC)
The word "recement" means exactly what it literally says. Dental restorations--that is to say, devices used to re-construct the shape and form of a damaged tooth (i.e., fillings, inlays, crowns, or veneers) often (but not always) need to be cemented to a tooth in order for them to be reliably retained in place. However, they don't always stay in place forever. The combined action of salivary dissolution and repetitive chewing force can cause disintegration of the luting cement over time, leading to loosening and displacement of the restoration. If there is no significant damage to the tooth by decay and the restoration still fits, it can be recemented in its proper position.
Whether a dental insurance policy pays a benefit for a recementation procedure depends on the provisions of the policy. However, most dental insurance carriers would much rather pay for a low-cost procedure such as a recementation than pay for an expensive replacement of an otherwise serviceable dental restoration. In the U.S., the insurance industry and the American Dental Association have collaborated on a set of procedure codes, and there are codes for recementation, giving the technique official recognition.

Why do different science disciplines not cross reference each other? Hence we seem to end up with only 20,000 years of human history but the globe being populated by man crossing land bridges that existed millions of years ago and no-one in the science community questions this.

Consider the loxodromic equations:
= The "vertical" (Δlatitude) "leg";
= The "horizontal" (adjusted Δlongitude) "leg";
= Graticular (spherical) azimuth;
= Loxodromic hypotenuse;
For the spherical loxodrome:
For the ellipsoidal loxodrome (referring here to an oblate ellipsoid []):
= equatorial, polar radii;
The ellipsoidal loxodromic azimuth has its own relationship set:
Likewise,
Hence,
The point of all this, is that it calls into question the validity of the classically prescribed arcradius at a given latitude, in a given direction:
At a given point, an azimuth is an azimuth: Whether it is loxodromic or orthodromic only identifies the "behavior" of the line it represents--an azimuth of 73.263° means, at a given point, a direction of 73.263° from due north, PERIOD (end of discussion). Right?
Now consider the prescribed, accepted equation of the arcradius:
= Graticular (spherical), orthodromic azimuth at Lat;
= Elliptical, orthodromic azimuth at Lat;
If one calculates a minuscule (ellipsoidal geodetic/orthodromic) distance and divides it by the spherical angular distance ("ADg", found via the "spherical cosines for sides" equation), it will nearly equal Oe{}, not P{}!
Consider this example (where , ):
Now compare:
This should demonstrate that Oe{} is the arcradius at (), not P{}, shouldn't it? If Oe{Aze:Lat} is not THE arcradius, then what type of arcradius is it? And if P{} is THE arcradius, then how does it relate to a minuscule distance?
I can't believe this concept is unknown—maybe archaic/obscure and/or just forgotten (or, more likely, known/recognized by another name—?).
Given that "original research" is a Wikipedia no-no, I would like to know if this concept/equation is recogized—or, if indeed this is OR, worthy of a paper at PlanetMath or some such site! P=) ~Kaimbridge~ 23:46, 29 October 2005 (UTC)
(comment and reply moved from my talk page—shouldn't the the discussion stay here?) ~Kaimbridge~ 20:36, 30 October 2005 (UTC)
Well, the "arcradius" itself is the problem! P=)
I know about geodetic formulation and its "conformal" nature, requiring an "auxiliary sphere" (I have copies of Sodano's and Vincenty's classic papers--as well as others--but I prefer Saito's straight-forward Gaussian Quadrature, all of which are given in Richatd Rapp's Geometric Geodesy, Part II <Ohio State Univ.>).
Since great-circle distance equals the (arc)radius times the angular distance, it follows that the (arc)radius equals the distance divided by the angular distance. So, on an ellipsoid, the smallest possible geodetic distance divided by its corresponding graticular/spherical angular distance equals the arcradius at that latitude, in the direction of the geodetic line. Try it on a meridian (which is a "simple" ellipse): Calculate a minuscule distance and divide it by ΔLat (which, in this case, equals the graticular angular distance)—it will nearly equal M{Lat}/O{0:Lat}.
Now, before you get ahead of the discussion and think "hey, wait a minute, I know what he is up to...he thinks he found a geodetic formula using just Lat/Long, not requiring an auxiliary sphere and all its complications...but he doesn't realize...". But, yes, I do realize this wouldn't find the traditionally defined, conformal geodetic distance, but it does find the graticular geodetic distance—what I call the "parageodetic" distance—which is the elliptical distance on a spherical globe: That is, calculate the angular distance between the two points on the spherical globe, then, staying constrained to the graticule (which, by its origin, is always spherical, thus "graticular"/spherical), find the average elliptical arcradius along that great-circle segment and multiply the two together (in the same way you would multiply the average value of M{Lat} <between and > by ΔLat to find the distance along a meridian <between and >). Think of the antipodal case: The geodetic distance will always be north-south, along a meridian, as that is "conformally" the shortest distance (i.e., if you theoretically pulled a string from a point on the equator, along the equator, to the other side, the string would "lift" until it is north-south, when it reaches its antipodal point), whereas the parageodetic distance would be the elliptical distance along any great circle (also known as a "transverse meridian") between and including a common, vertical meridian and the common, horizontal equator. There is a popular geodetic approximation ("Andoyer's Approximation") that is actually a parageodetic approximation!
But I realize that the "parageodetic"—as far as I know—would be considered waaaaay out into original research land, so I'm not attempting to go anywheres near there! P=)
The idea of O{Azg:Lat}/"omniversal"/"transverse neridional" arcradius (at least in some form), however, I don't think is OR (especially if it is presented right). I suspect that it may just be a mostly forgotten concept, given all of the advances in geodetic formulation for finding the "shortest" (i.e., conformal) geodesic. Either that, or P{Aze:Lat} is supposed be the "omniversal"/"transverse neridional" arcradius in some other reference form (e.g, "reduced", "parametric", etc.), with some way to convert it to the more apparent Oe{Aze:Lat}—thus the question to the RD.
As for all of the loxodromic intro, that is meant to be an attempt at presenting O{Azg:Lat}'s derivation. ~Kaimbridge~ 15:46, 30 October 2005 (UTC)

Hello, all. Before I purchased my new laptop, my old laptop was giving me quite a lot of problems. What happened is that sometimes, the LCD display would show some sort of "snow", but differently. If you had, for example, three white pixels aligned horizontally, a magenta pixel would appear next to the third pixel. Also, if there was a black pixel below and left of another pixel, that pixel would appear lime green (my guess is hexadecimal #00FF00). I don't use it anymore, but I've always wondered what was causing the problem. All the connections were properly plugged (I checked them myself several times), and I've heard somewhere that it could have been because of a property of LCDs, but I didn't get more explanations. Is that possible? If it is, what was causing it? Titoxd(?!?) 03:47, 30 October 2005 (UTC)

Inspired by the biology question above, why is it that when I look at a tainted window on the outside it has the same colour as when I look at it from indoors? If the colour on the outside is a reflection of that wavelength, then on the inside I'd have to see white light without that wavelength, so the complementary colour. On second thoughts, I'd have to do this test with the lights out on the inside. Would that be the cause of it, that I see the reflection of the lights inside? But they're much weaker than sunlight, so that sounds unlikely. DirkvdM 07:21, 30 October 2005 (UTC)

I don't have a clue how elemental carbon would be used in dentistry, at least the way it is practiced in the United States. This is a stretch, but some water purification systems in dental equipment may contain activated charcoal filters.
Of course, carbon is part and parcel of all organic life, which pertains to dentistry, as it does to all the health professions. Dental burs ("drill bits") may be composed of carbon steel, and are tipped with tungsten carbide. But elemental carbon? I don't think so...

Hello, this is related to another question I saw on another page. My question is I know that the chemical methane is added to the nicotine leaves to aid in burning. Would the leaves be able to burn or burn well without this chemical and how is it that the smoke doesn't blow up since it is a dangerous chemical when someone lights up? Also, what other chemicals besides methane are added to the niotine leaves not the paper to make it burn and burn slowly?
Without the methane and excluding the paper would the dried tobacco leaves be able to burn or are they dependent on the methane to burn?
What about other chemicals like ethylene or butane are those added to cigarettes and do those also aid in the burning of the tobacco leaves? Also how are these things added, I read about how tobacco companies shred the dried leaves then they add the top dressing as they called it by spraying it on, but that also includes strange things such as chocolate and honey and coffee, how do these things along with the chemicals remain on and not make the leaves soggy and the chemicals not be watered down so they work effectively?
This question goes back to the original question about methane. You mentioned that a very low concentration of methane helps slowly burn without being dangerous, how much would be considered a low concentration and what concentration leve does it get dangerous?

As per different standards of indented prestressting steel wires, it is seen that as the diameter of wire increases Ultimate Tensile Strength (UTS) decreases. As an example minimum UTS of 4 mm dia wire is 1715 N/sqmm while that of 5 mm dia wire is 1570 N/sqmm.
When enquired from different manufacturing agencies, it is learnt that while drawing from same parent material, by cold drawn process, Breaking load decreases which is not in the same propotion as that of diameter. Since UTS = Breaking Load/Area, it varies.
Why the Breaking Load of these steel wires does not decrease in same propotion as that of diameter of the steel wire? Is there any molecular changes involved in it, if so what is that?
MALOY NANDI
It's not directly related to the diameter. Nor is there any kind of molecular change cause by an increase or decrease in diameter. See Strength of materials, and also check out Solid Mechanics on the Wikibooks site. Proto t c 09:53, 31 October 2005 (UTC)
Then why does UTS decreases with increase in diameter of Plain Drawn Steel Wire?
MALOY NANDI
It's to do with its Young's modulus, and the relationship of stress and strain. The relationship is different for every material. Read the article on the Wikibooks site. Proto t c 12:30, 31 October 2005 (UTC)
As per Indian Standard Code (which are practically photocopy of British Standard), minimum Ultimate Tensile Strength (UTS) of different sizes of steel prestressing wires are as following –
Dia of wire UTS (N/mm2)
It is seen from above table that UTS of a plain drawn steel wire decreases with increase in diameter of the wires. What is the reason for this variation if parent material remains same, with no change in chemical properties?
It is understood from the discussion with different manufactures (TATA Steel), during cold drawing process Breaking Load decreases, but not in same proportion, with decrease of diameter of wire. What is the reason behind it and what changes are taking place within the hard drawn steel?
MALOY NANDI
There is no heat process involved in cold drawing process. Larger dia wire (e.g. 8 mm) is passed through various dies of smaller diameter to get smaller dia wires (e.g. 4 mm/5mm etc.). Resultingly UTS of wire increases.

I understand the electron mass is the best measured particle mass, to an accuracy of some 10 digits. I am wondering if there have been any attempts to test whether the mass is in fact a constant, or if it is changing over time (if the mass changed significantly over cosmological times, there could conceivably be a change in the 10th digit over a few decades or so). And, which property is actually measured in this precise number of e mass: is it the relation to the proton mass? Which definition of the kg is intended when they say m=0.510998918(44) MeV/c**2 ? Would a change in elementary particle mass that leaves the ratio of e to p masses intact even be registered, or would that be equivalent to a change in the gravitational constant? Baad 08:12, 31 October 2005 (UTC)
I vaguely remember reading about some confusing atomic spectral data from extremely distant quasars (unresolved distant galaxies) indicating that the fine structure (or hyperfine structure??) structure seems to have changed, as compared to what it is in modern times. I don't know if other astronomers confirmed this or not, and am not clear of what the other interpretations are. However, changing fine structure indicates that either the electron mass or the electron charge or both are changing. Theories to explain this will be all over the map; it will be at least decades if not half-a-century to narrow things down for "extreme physics" questions like this. FWIW, the variation of Kaluza-Klein theory as practiced by Paul Wesson et al. has masses changing by about 10% over about 10 billion years. Here's the fun bit: in their theory, the origin of mass is due to geometry of the 5D KK space, and all sorts of funny things result: for example, mass change is equivalent to Hubble expansion. Note also, changing fine-structure consts does change biochemistry, among other things ... linas 04:45, 1 November 2005 (UTC)

Why can't you take the flu jab when you are sick?
Because it gives you a very mild case of the flu, and if you're already sick, it can be exacerbated into a more serious case as your body's defenses are weakened. Proto t c 09:43, 31 October 2005 (UTC)
Not quite. For most people, it doesn't make you sick. The two reasons are (1) liability and safety, and (2) the theoretical concern that effectiveness may be reduced. If a person is sick, he can be sick in many ways and there are many different outcomes (from full recovery, to complicated illness, to death). Although it is extremely unlikely that this type of intervention would change the course of a current illness, the doctor caring for the patient and the person or organization or corporation providing or making the flu shots do not want another variable added in to the illness and especially do not want the flu shot blamed for the outcome of the illness. A lesser reason is that during the acute phase of another viral infection, the immune response to a flu shot might be altered in such that the long term protection response may be lessened. This is mainly a theoretical concern and has not been proven or even well-studied. alteripse 12:17, 31 October 2005 (UTC)
Why is chlorophyll green in colour??? I mean why it has to be green to be able to absorb light?
(From the article) Chlorophyll absorbs mostly in the blue and to a lesser extent red portions of the electromagnetic spectrum, thus its intense green color. This applies to plant chlorophyll. Chlorophyll does not always have to be green – there are also purple bacteria, which use bacteriochlorophyll, which absorbs infrared light. Proto t c 09:48, 31 October 2005 (UTC)
The only cost/benefit that I can think of does not relate to the chorophyll. Each photosytem that absorb photons has hundreds of pigment molecules, including carotenoids. Photons absorbed in the spectrum transfer energy to the reaction center and excite the electron to an electron acceptor molecule. Since one reaction center has coopted many pigments it is rare that the supply of electrons is so limited that even the green light has to be harvested. There are exceptions such as shade tolerant plants that see a few speckles of sunlight, their leaves are often very dark green (almost black). Their existance would argue that the need for more photons is not limiting full sun plants and hence losing the green photons does not enter the cost benefit analysis. The only cost I can think of for absorbing green is that the plants heat too much from the inefficient transfer of energy to the photosystem reaction center (energy is lost as heat which is bad for a leaf). However, if that was a real cost it would be the blue end of the spectrum a plant would want to reflect since those photons are higher energy than the green photons. In fact, some plants do have waxes on their leaves to reflect blue light to reduce the heating. In summary, the best argument for a cost benefit argument is the overheating problem from harvesting too many photons but this seems to relate to the plant as a whole NOT to the synthesis of chlorophyll. In general there is no need for a better pigment as there are several pigments than can be combined to adjust the total absorbtion to suit the plants specific environment. David D.

What is the purpose of pubic hair growing around the reproductive organ of both man and woman?
See puberty and pubic hair. Proto t c 09:44, 31 October 2005 (UTC)
Note that the age marker theory is the only one which explains why children lack such hair. Heat loss is actually more of a problem in children, due to their higher surface to mass ratio, so hairiness in children would be a widespread trait if the primary purpose of body hair was heat retention. If body hair was primarily for heat retention we would also expect far more in ethnic groups native to colder climates, and little or none in those native to tropical climates. Also note that facial hair in men is both an age marker and a gender marker. As for the lubrication theory, I wasn't only talking about during sex. Legs rubbing against genitals during walking could produce a rash if no hair was present. Underwear somewhat reduces this problem, however. StuRat 23:38, 31 October 2005 (UTC)

The axiom of regularity
Axiom of regularity (or axiom of foundation): Every non-empty set x contains some element y such that x and y are disjoint sets.
Disjoint: Maths (of two sets) having no members in common (Collins Dictionary)
This makes no sense to me. How can x and y have no common elements if x contains y. Surely y is a common element.

Doing some reading on talkorigins.org led me to trueorigins.org and a few of their articles. There seems to be a creationist idea that Darwin nicked the idea of natural selection from Edward Blyth, who was a creationist. I ask because the Wikipedia article on Blyth (see above) mentions this. How legit is this? I hesitate to believe a darn word the creationists say, which is why I bring this up. grendel|khan 18:13, 31 October 2005 (UTC)
To expand further on the idea that children aren't being taught evolution well enough, many evolutionists are very happy to announce that a belief in evolution increases with greater education, meaning that children need to think it out for themselves over time and often do come to the thought of evolution. However, they had to be taught this very well over a long time. Many had to rethink their faiths and their schema of the world greatly. You make it sound very simple because you probably never had to. You were taught one pattern and one idea about your origins and your life and never had to "use your brain" to really think it out. Breeding and genetic variation are very good examples, but in order to say definitively evolution does exist required a lot more evidence and solid facts than you give credit for. You continually compare yourself to a higher individual or a free-thinker much like that Greek you made up, but in fact, you must remember, you didn't discover evolution. You had the evidence and the knowledge accumulated for you and you had to use that to learn the truth. I largely doubt your sure-fire thought that evolution is "obvious". The same goes for your approach to teaching it to children. You say, tell them to see it for themselves. You can't say you saw evolution. You can't just say "believe it like I did" right away and say "it is extremely obvious". Another thing of interest is the immediate separation you make, almost like religious denominations. "well, some [will take it] anyway". That means you want some to just believe something because you say so and would separate yourself from the others, telling them to "go look and you can see evolution", practically ignoring any criticism of your ideology. That isn't science. A scientist would defend his theories. To say "some will learn it, the rest will have to go look for it" is not scientific or educational. That is dogmatic in a sense. Again, don't take what you know of in such an arrogant form. The ideas of evolution are the result of an "evolution" of theories and evidence that eventually led to more concrete knowledge. It isn't a process you can go out and demonstrate to the class. It is indeed not obvious, but more of a learned and complicated branch of knowledge. It is among the fundamentals of science, crucial to our understanding of living things, but is not very "basic". Even the basic models have experienced scientific thought--gradualism, punctuated equilibrium, and genetic variation--all added and combined to make the theory bigger and better, so it wasn't an unmoving and stable idea that you can "see for yourself". Don't confuse science with dogma and don't think the education system is doing such an adequate job if we can see great confusion among school districts across the country.--Screwball23 talk 17:17, 3 November 2005 (UTC)
