yesterday, March 14th was "Pi" day -- 3.14. Can't believe Dave and Ginger let that one pass by unnoticed. :wink:
My wife (math teacher) celebrates Pi Day in a variety of ways at school. One of the popular things is to have a contest of how many decimal places a student can memorize. The most so far at her school is 191.
