Today is a pretty nerdy day. Specifically at 9:26.53AM. Why? Because the abbreviated date (minus the "20" of 2015) will be pi, the ratio of the circumference of a circle to its diameter, taken to 10 places! Happens only once every 100 years, so nerd it up and eat some pie (and if you're really nerdy use pi to figure how just how much pie you ate.... or just eat some pie).
Email conversation between my sister and me on May 3, 2013 after sending her this graphic over Pinterest:
3/14/15 9:26.53 is almost as nerdy as 10/10/10, when my physics class had a pizza party to celebrate the answer to life, the universe and everything (or 42 in binary).
