   [...] Pi day would be 31/4 or the 31st April (a non-existant day). Fitting really given that it is an irrational number. I suggest that perhaps the better day would be the 22nd July or [...]

   Actually, about Pi-Approximations, today I got up extra early, went to the Math Drop-In Center at my school, and planning to write out some happy digits of Pi on the blackboards. I got annoyed with writing digits in chalk after about a dozen or so, and then just opted to write my favorite infinite product representation of Pi (The Wallis Product). Through out the day some of my friends, and faculty added their favorite formulae. Much fun for the whole department!

   In elementary school, I learned to approximate pi using twenty-two divided by seven. Following CoreEcon’s suggestion (European style date), pi day would be July, 22… But, it appears Americans decided to set the date at 3.14!

   @licia: that’s because Americans can’t work with fractions.

   Okay, I’ve been teaching too long. I’m jaded. Please forgive me.
