Happy 3-14 or Pi Day

Happy Pi Day! It is March 14 (or 3.14) which starts off the infinite sequence which is equal to the ratio of a circle's circumference to its diameter.

Today fans of Pi are meeting to celebrate.

And once a year many of them gather to talk about pi, rhapsodize about it, eat pi-themed foods (actual pie, sure, but so much more), have pi recitation contests and, just maybe, feel a little less sheepish about their unusual passion.

Today happens to also be Albert Einstein's birthday.

(Is that too nerdy?)
