This very quick read is neither complete (there are websites for that, referenced in the introduction) nor comprehensive (it can be sold to those without a math PhD). It was enjoyable.

Each chapter starts with a reference or three from the Simpsons (and later Futurama) then moves forward to explore the mathematical concept referenced (from Pi and Fermat to Topologies and Klein Bottles, with a side trip into Bill James and Erdos/Bacon Numbers). The explorations are necessarily brief. Singh also introduces the reason for all this math - the nerdy writers of both shows.
