Happy Pi Day!
Although it's probably not marked on many of your calendars, today is international Pi Day! No, I'm not talking about apple pie, pumpkin pie, or even banana cream pie; I'm talking about pi, that seemingly never ending string of digits that starts out 3.14159 and is part of the relationship between a circle's diameter and circumference.Rock on all you math geeks out there!
