I chose to focus on the development of its approximation as a hook to teach the broader history of mathematics, rather than make this video an exhaustive list of facts. The wiki is a great place to learn more about the rest of the number's history and applications in maths and \u003ca href='https://en.wikipedia.org/wiki/Pi#History' target='_blank' rel='nofollow'\u003ephysics\u003c/a\u003e A few nitpicky things: - I made mistakes distinguishing between 'digits of pi calculated' and 'decimal points of pi calculated' in some sections, so it is possible that this error is elsewhere without me knowing. - Archimedes didn't do his approximation with squares, he started with hexagons and then increased the order of the polygon. I chose to present the zeroth order version of his algorithm using squares for simplicity, but note that this is not what he did. - Something which got lost from the final version of this video is my argument that during the Age of Enlightenment pi shifted from being a physical (measured) constant to a purely logical (theoretical) one. This then embodies the philosophical shift in society at the time. This is hinted at but not fully explained, so I thought I'd put this here. - Lastly, I am truly sorry for the pronunciations which I doubtlessly completely murdered in this video. At least I spared you my attempt at Chinese. I am hugely indebted to Alex Bellos and his excellent book Alex's Adventures in Numberland for the inspiration to make this video. There is an entire chapter of the book devoted to a broader but shallower discussion of pi and its history, which I highly recommend.
