Over many years, the popular animated TV series The Simpsons has included numerous references to mathematics and even featured a mathematician as a character on the show. This Web site provides an episode-by-episode listing of references to math in The Simpsons, compiled by mathematicians Sarah J. Greenwald of Appalachian State University and Andrew Nestler of Santa Monica College. The site also offers entertaining classroom math activity sheets, many inspired by Simpsons references, on topics ranging from pi and the Pythagorean theorem to calculus and probability.
