Greetings once again, one and all!
It is PI DAY, y’all – gather round and roll out the red carpet for that most glorious of numbers,
In fact, though we made a big deal of last year’s celebration as the “Ultimate Pi Day”, or the “Pi Day of the Century”, a case can be made that today is even more special! Today’s date, 3/14/16, is a rounded-up version of pi to four decimal places (rather than a truncated version like last year); it also only comes around only once a century; and in fact 3.1416 is about nine times closer to the actual value of pi than 3.1415 is! 😉
If you’re a little bummed out that we won’t have a “pi day of the century” next year (after all, 3.1417 doesn’t seem too special), check out this article (via MAA) which proves that, for some norm other than the Euclidean distance, there is a “pi” for that norm that will match that year–thus every pi day can be the “pi day of the century”!
OK, here’s your round-up of cool pi links:
- Mile of pi: a video where some math folks print out a million digits of pi, then lay that out on an airport runway, highlighting some interesting pi facts along the way
- “6 Things You Probably Didn’t Know About Pi” (well, I knew most of them, but they are still interesting reminders of pi’s awesomeness)
- A cartoon called Pi vs. Pie
- Pi & the Simpsons, video by math author Simon Singh
- 8 Forgotten Pie Recipes We Should Bring Back
- A Happy Pi Day wish from President Obama
- (An old favorite): Pi & Poe (a Ravenesque piem, which can be used as a mnemonic for pi’s digits)
- A more philosophical take: why we need math and a pi holiday, by Darren Glass
- And, finally, a non-pi related article by Evelyn Lamb, on a result which just happened to be mathematical breaking news today, on unexpected patterns in the prime numbers!
HAPPY PI DAY !!!!!!!!!!!!!!!!!!!!!!/!!!!!!!
