QED: The Strange Theory of Light and Matter by Richard P. Feynman [Repost]

Famous the world over for the creative brilliance of his insights into the physical world, Nobel Prize-winning physicist Richard Feynman also possessed an extraordinary talent for explaining difficult concepts to the nonscientist. QED–the edited version of four lectures on quantum electrodynamics that Feynman gave to the general public at UCLA as part of the Alix G. Mautner Memorial Lecture series–is perhaps the best example of his ability to communicate both the substance and the spirit of science to the layperson.
