Happy Pi Day

Today is Albert Einstein's birthdate, and appropriately enough, pi day as well. For those who may have slept through high school math, pi is not only the 16th letter of the Greek alphabet, but a lengthy transcendental number that stretches to over a trillion decimal places. It is commonly abbreviated to a more usable, albeit slightly inaccurate, 3.14 - hence the date it is celebrated, March 14. The most common usage of pi is in calculating the circumference or area of circular objects.

While presented somewhat tongue in cheek, here are a few pi related links that hard-core eggheads may find amusing.
