Pi Day Womens


What do you call a number that can’t sit still?
March 14th (or 3/14) is the day we celebrate the Greek letter “π” as a mathematical constant that represents the ratio of the circumference of a circle to its diameter. The Babylonians (1900 – 1680 B.C.) and the Egyptians (1650 B.C.) were the first to estimate pi’s value between 3.125 and 3.1605, while Archimedes of Syracuse (287 – 212 B.C.) calculated a close approximation. Pi is a lot older than you thought, isn’t it? Today we lovingly know π as 3.141592653589793 … (you get the picture).

Some people think celebrating “π” is “irrational,” but they also probably think Pi Day is only about pie so we will just leave them be.
Enjoy your shirt and celebrate Pi all year!
