Yes, it’s Pi Day; but not just any old 3.14 Pi Day – which is also Albert Einstein’s birthday – today, 3-14-15, is a once-in-a-century Pi Day. Plus I made it even more extra-special by having it publish at 9:26 East Coast time; unfortunately, WordPress doesn’t have a place to put the 53 seconds to make it 9 decimal places. But at least I got 7 places with 3.1415926.
An article by Sasha Volokh in yesterday’s Washington Post has hints for “How to Observe Pi Day 2015“: including, for the real geeks, the author’s own mnemonic for remembering 167 digits of pi. Here’s an excerpt from the article:
“One of the best pi mnemonics, which gets up to 740 digits, is a retelling of Poe’s The Raven; here’s its first stanza:
Near A Raven
Midnights so dreary, tired and weary.
Silently pondering volumes extolling all by-now obsolete lore.
During my rather long nap – the weirdest tap!
An ominous vibrating sound disturbing my chamber’s antedoor.
“This”, I whispered quietly, “I ignore”.’
This is actually the beginning of a super-long work called Cadaeic Cadenza by Mike Keith…”
[I hope that Wayne doesn’t consider this to be a challenge to his mathematical mind and his parody talent.]
Apparently, Pi Day is ‘celebrated’ by enough people that there are sites selling T-shirts, posters, stickers, etc., with various pi (and pie) related themes. Many of these items are available at Pi Day’s own website, www.piday.org, for true devotees. And some people are even inspired by Pi Day to make pi-themed pies and other treats.
Okay, this is way too much pi for one morning – I’m stuffed.
This is our daily Open Thread – go ahead, discuss pi, pie, or anything you want to.
