If superheroes stepped off the comic book page, could they actually work their wonders in a world constrained by the laws of physics? How strong would Superman have to be to 'leap tall buildings in a single bound'? Could Storm of the 'X-Men' possibly control the weather? James Kakalios provides an engaging and witty commentary while introducing the lay reader to both classical and cutting-edge concepts in physics, including: what Superman's strength can tell us about the Newtonian physics of force, mass, and acceleration; what villains like Electro and Magneto tell us about electricity and magnetism; how Iceman's powers show the principles of thermal dynamics; what the Human Top can tell us about angular momentum; why physics professors gone bad are the most dangerous evil geniuses... and more!
