• No copyvio, 5x expansion all good. Could we re-word the hook slightly? I feel there is a good hook in there somewhere, but I'm not sure it reads too well. Could you explain what "minimisation of component count" actually is? Maybe slightly different wording to be easier to read would help (this might be wrong, but how about: ALT1: ... that despite great effort, in network synthesis a general theory for component count minimalisation has yet to be found?) I feel even this doesn't quite meet this. Best Wishes, Lee Vilenski ^{(talk • contribs)} 11:25, 10 May 2020 (UTC)

  • ALT2 ...that network synthesis researchers have long sought to minimise the number of network components, but this is still an unsolved problem?
  • ALT3 ...that interest in network synthesis research is now greater than at any time since the 1950s due to its new applications in mechanics, particularly Formula One? Source: Chen & Hu, p. 8
    • seems fine to me. I like ALT3 personally. Lee Vilenski ^{(talk • contribs)} 17:31, 10 May 2020 (UTC)

• Hi, I came by to promote ALT3, but I'm not seeing the hook fact with a citation. I'm referring to the greater than at any time since the 1950s due to its new applications in mechanics, particularly Formula One. Could you point it out please? Yoninah (talk) 21:05, 11 May 2020 (UTC)

It does say it, but not all in one place;

• "Papers achieving this include Pantell (1954), Reza (1954), Storer (1954) and Fialkow & Gest (1955).[13] As of 2008, there has been no further significant advance in synthesising rational functions.[14]"
• "In the 2000s, interest in further developing network synthesis theory was given a boost when the theory started to be applied to large mechanical systems.[25]
• Mechanical components with the inertance property have found an application in the suspensions of Formula One racing cars.[36]

From the sources,

• "Passive network synthesis is a classical subject in electrical circuit theory which experienced a 'golden era' from the 1930s through to the 1960s. Renewed interest in this subject has recently arisen due to the introduction of...the inerter and the possibility to directly exploit this approach to vehicle suspension..." (Chen & Smith, p. 35)
• Inerter has been successfully applied in Formula One racing cars...The interest in passive network synthesis has also been rekindled." (Chen & Hu, p. 8)
• Bott (wisely) dropped the topic immediately after his doctorate, and no one was able to do anything with it after him. (Kalman, p. 10) (Bott's doctoral thesis was 1949)

@Yoninah: Sorry that's so messy. SpinningSpark 09:11, 12 May 2020 (UTC)

• OK, now I see what you're saying. It would just be easier to add the second and third cites to the last sentence in the lead, which encompasses the hook fact. But I'll replace the tick. Yoninah (talk) 13:52, 12 May 2020 (UTC)
