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 society as a whole puts on a bunch of purple felt jump suits and hitches a ride on a nearby comet. Those people arent reading this description though. They are browsing the howtothinklikeaflower.com website. 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. Metro blue 100% cotton heavyweight 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.
