I have just published a new book about all the cool science on The Simpsons, from Bart's comet to Lisa's perpetual motion device and Homer's theory of a donut-shaped universe. It also discusses the feasibility of many of Frink's inventions, from shrink-rays to teleportation devices. Homer's time-traveling toaster and Bart's time-stopping watch (from the Treehouse of Horror segments) are even in there. Chaos theory, and how it relates to Itchy and Scratchy Land, has its own chapter. And for fans (or ex-captives) of Kang and Kodos there is a discussion of the Rigelian language and why we haven't yet encountered real-life aliens.
The book is called "What's Science Ever Done For Us? What The Simpsons Can Teach Us About Physics, Robots, Life and the Universe."
