Pi by Numbers

What is Pi? Some might define it as the ratio of a circles circumference divided by its diameter. Others might think its an irrational number thats impossible to know completely. Still others might think its a mystical, transcendental, almighty number that will only finally be revealed when the Mayan calendar ends. Those people are probably putting their affairs in order, though, and not so much reading this site. But we digress...

We here at ThinkGeek like to think of Pi as a way to help you come up with creative reasons to spend your hard earned cash on a t-shirt. Quick question. When is Pi day? March 14th of course. Think about that for a second. Now, while still mesmerized, drop this shirt into your shopping cart.

Royal blue, 100% cotton, kids t-shirt with the Pi symbol on it. The first 4493 digits of Pi were used to construct the Pi symbol itself. Thats a whole lot of Pi. Enough for everybody to share so dont get greedy on us now. A big shout out from ThinkGeek goes to Archimedes way back in the B.C. for finally giving us a good approximation of Pi, and doing so without the benefit of modern trigonometry. And thanks to the Egyptians and Babylonians for trying.
