In case you don't remember, the mathematical constant Pi is 3.14...and Thursday is March 14 - or 3.14. It is day to celebrate the ratio of a circle's circumference to its diameter. RAISE THE ROOF!

Pi is an important part of geometry, trigonometry and physics. And today is the day to show off how many places you can name it to. Not to brag but, I can go all the way to two. That's right ladies, two places, 3.14.

March 13 is also Albert Einstein's birthday. Coincidence? Probably.
