The Pigeonhole Principle is one of the most unusually useful results in all mathematics. If there are more pigeons than there are holes, at least one hole has at least two pigeons. With this comfortable t-shirt, you can show off your love for this classic result with adorable math pigeons. The design features five legendary mathematicians in their pigeonholes - Euclid, Fermat, Euler, and Gauss - and the Bernoullis (Johann, Jacob, and Daniel) all squeezed into one pigeonhole.
