We should probably give a big thanks to Archimedes before we even think of putting on this t-shirt, who without the help of modern trigonometry found an approximate value of the Pi, which the Egyptians and Babylonians tried for centuries and still couldn’t find it, i.e 3.141. 
The Pi or rather ? (in the actual Greek form) is defined as the ratio of the circle’s circumference divided by it’s diameter, which has been puzzling many for centuries, and now we finally have a good approximation of it’s value in the form of this T-shirt.
The T-shirt portrays a humongous ? on it’s front which is actually made up of the first 4493 digits that appear in the Pi’s approximate value, pretty cool right? Selling for $15.99-$16.99, this metro blue colored tee is a sure addition to every geek’s wardrobe and Cool Tees list, so get your own soon and mesmerize the folk around you.
