Thank you Google Reader for giving us interesting things to check out and report on.  We suggest you check out the short podcasts at the Web site of the American Association for the Advancement of Science.  Some are quite entertaining:

“The Science of Superheroes,” for instance, is an interview with University of Minnesota physicist James Kakalios, who uses comic books to teach introductory physics. He explains that there are good scientific explanations for why the Flash is able to run across the ocean and why Spider-Man’s girlfriend died after being pushed from a bridge by the Green Goblin, even though Spider-Man managed to catch her in his web midfall.
