Happy Pi Day!

by Laurie McAndish King on March 14, 2010

Today — 3/14 — I’m celebrating pi, the ratio of the circumference of a circle to its diameter, the irrational, transcendental, infinite mystery number: 3.1415926535897932384626434….  (If this isn’t enough detail for you, the first 10,000 digits of pi are listed on The Joy of Pi website.)

Today also happens to be Albert Einstein’s 131st birthday; party on!
