Hello World!!

My name is Tahmid Hossain and I hail from Bangladesh. I am surfing Wikimedia projects since 2016 (though I created (this) account in February 2017). I mostly contribute in wikidata, Wikimedia commons, and Bengali language projects.

I mostly contribute to wikidata. I also contribute to various Bengali-language projects. So far I have made 3,300,000+ edits after creating this account. Although a large portion of my edits are done using various automated or semiautomated tools. You can see my contributions to all Wikimedia projects on the CentralAuth page.

• Physics is the natural science that studies matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves.

• The universe is all of space and time and their contents, including planets, stars, galaxies, and all other forms of matter and energy. The Big Bang theory is the prevailing cosmological description of the development of the universe. According to this theory, space and time emerged together 13.787±0.020 billion years ago, and the universe has been expanding ever since. While the spatial size of the entire universe is unknown, it is possible to measure the size of the observable universe, which is approximately 93 billion light-years in diameter at the present day.

• Artificial intelligence (AI) is intelligence demonstrated by machines, as opposed to the natural intelligence displayed by animals including humans. AI research has been defined as the field of study of intelligent agents, which refers to any system that perceives its environment and takes actions that maximize its chance of achieving its goals.

• In the history of science, Laplace's demon was a notable published articulation of causal determinism on a scientific basis by Pierre-Simon Laplace in 1814. According to determinism, if someone (the demon) knows the precise location and momentum of every atom in the universe, their past and future values for any given time are entailed; they can be calculated from the laws of classical mechanics.
