Make the Switch to Tau! Math T-Shirt

Tau, written as tau = 2*pi, represents one full turn around a circle. Its signature use is making circular relationships read in full turns rather than half turns, which is why tau has a loyal mathematical following. It is a clean way to talk about angles, periodicity, and rotation when the whole circle is the natural unit.
