Celebrate Pi Day - March 14th

Pi, about 3.14159, is the mysterious mathematical constant (number) that represents the ratio of any circle's circumference to its diameter.

Mmmm. Pi Day! The nerdy holiday celebrated by math geeks worldwide. This is the day they collect around to celebrate that tremendous small (long) number, pi.

Pi has its day, appropriately, on March 14 (3/14). Often a Pi Day celebration will have an additional special event set for pi minute (at 1:59pm). In the United Kingdom, Pi Approximation Day is often celebrated on July 22 (22/7) as 22 divided by 7 is an approximation for pi.

This day brings more fun to math classes around the globe then anything else (second only to Math League). I wish you a Happy Pi Day 2011!
