Celebrate Pi Day - March 14th
Mmmm. Pi Day! The nerdy holiday celebrated by math geeks worldwide. This is the day we gather around to celebrate that amazing little (long) number, pi.
Pi, approximately 3.14159, is the mysterious mathematical constant (number) that represents the ratio of any circle's circumference to its diameter.
Pi has its day, appropriately, on March 14 (3/14). Often a Pi Day celebration will have an extra special event set for pi minute (at 1:59pm). In the UK, 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 world then anything else (second only to Math League). I wish you a very Happy Pi Day 2012!
