Happy Pi Day!

Today is 3.14 2007, or Pi day if you are in the know. Pi, is the symbol for the ratio of the circumference (around the circle) of a circle to its diameter (across the circle). Pi is usually calculated to 3 digits, 3.14. Pi is an irrational number meaning it will continue infinitely without repeating. There is no end to Pi! With the use of computers, Pi has been calculated to over 51 billion decimal places to date.

The number is so long that there are actually contests to see who can recite the most places in Pi. Earlier this year a man from Pennsylvania recited 12,887 digits, to be exact. It took him 3 hours and 40 minutes to do it. When he ended, he became the North American record holder. The previous record holder had recited Pi to 10,980 places.
