The Simpsons - a cartoon for mathletes

The Guardian reports that the popular long-running TV cartoon series the Simpsons is written by and for math geeks. Apparently hidden within many episodes are references to obscure (and not so obscure) mathematical expressions, formulae and facts including: Fermat's last theorem, perfect numbers, a narcissistic number, a Mersenne prime (all shown in the picture to the right), Euler's identity, a googolplex, the mass of the Higgs boson, appearances by the French mathematician Blaise Pascal, numerous jokes about π and of course the all important geometry of doughnuts. And you thought it was just a kids show.
