Pi. You remember, right? That number from high school math class that has a definite beginning, 3.14, but seemingly no ending. Used in formulas to determine circumference and diameter and something like that.

Today is Pi Day. I was really excited too. I heard it was pie day and I started getting hungry. But no. Just Pi Day. A number that even the smartest super computers can't find an ending. A million numbers and still going. One guy managed to memorize enough numbers of Pi that when he recited it back, it took 24 hours.

Why would you celebrate this?!?

Well I'm going to celebrate. By eating pie. Crack pie from Momofuku's. But for the rest of you here are some facts and ways to celebrate Pi day.
