Pi Day 2009
|
Pi Day is a celebration of the number π that occurs every March 14 (3.14...). Math geeks all over the world celebrate their math-geekiness on this day with pie-eating contests, recitations of the digits of pi, and occasionally fundraisers where math faculty get hit in the face with pies. At Brainfreeze Puzzles we celebrate Pi Day - how else? - with a Sudoku puzzle. |
