I've just published a new book about the intriguing world of science
on the Simpsons called:

What's Science Ever Done For Us? What the Simpsons Can Teach Us About
Robots, Life, and the Universe

http://www.amazon.co.uk/Whats-Science-Ever-Done-Us/dp/0470114606

It features the fascinating real-life science behind dozens of classic
Simpsons episodes, exploring questions such as:

Could Homer's theory that the universe is doughnut-shaped really be
true?  Learn how astronomers are currently trying to test this idea.

Are there really three-eyed fish in nature, like Blinky, or are
sightings of such creatures just hoaxes?

Read about how a Simpsons fan grafted tomato and tobacco together to
produce his own tomacco plant.

On Ray Romano's visit to the show, only Homer could see him.  Explore
scientific attempts to produce cloaks of invisibility.

Are shrink-rays, time machines and teleportation mechanisms
scientifically possible, such as the devices built by Professor Frink?

Do sinks and tubs in the Northern and Southern Hemispheres really
drain in different directions, as Lisa suggested in the episode "Bart
vs. Australia?"

The episode Homer^3 envisioned Homer stepping into a higher
dimension.  Learn about scientific theories that the visible universe
could be an island floating in a sea of even higher dimensions.

Many of the Simpsons writers have scientific backgrounds and have
included clever references to their fields in a number of episodes.
"What's Science Ever Done For Us?" is an entertaining guide to these
issues, just in time for the Simpsons Movie.
