The 14th of March offers many things. A chance for calendar nerds to get all excited about the meaning of “ides”. A chance to bring out Pi-related content on mathematics blogs. I’ll take advantage of the latter. There’s not a lot in public dispute about the ides of March. The ides of February, now, that I’m not sure I can talk about coherently. But, for Pi:
- The End 2016 Mathematics A To Z: Normal Numbers which is relevant because π is probably a normal number. We don’t know, but it would be really weird if it weren’t. Normal numbers are weird, but most numbers are normal.
- Calculating Pi Terribly was my first, big, and basically sour essay about π. It describes the Buffon needle drop experiment, which is a real experiment you could do with actual physical objects if you wanted to eventually, someday, calculate the digits of π. You should use basically any other approach before this if you actually need to know them.
- Calculating Pi Less Terribly is a follow-up, about finding the digits of π using way less work. It gets into alternating series, which are mathematically interesting enough and very useful.
Enjoy, I hope!
