It's physics, my dear Watson

"Physics can be like a universal tool kit for solving mysteries. It does not come with instructions, but if you figure out how to use it you’ll find that it comes equipped with everything you need to discover whether or not an ancient pyramid has hidden chambers, how to explain discrepancies in the JFK assassination footage, or find substantial evidence that a meteor impact killed the dinosaurs. And for those who don’t know how to use the tool kit, be sure you get a detective like Luis W. Alvarez." http://physicsbuzz.physicscentral.com/2007/11/its-physics-my-dear-watson-or-pyramids.html
