QED: The Strange Theory of Light and Matter

Recommended by Eliezer Yudkowsky (see below), and at r/HPMOR. Sounds like a super look at quantum stuff and a great example of Feynman's explanatory power. Yudkowsky has said, however, that later developments in the field have caused this book to lose some of its relevance, and that his own summary should be read also.

So what's up with all those whizzing atoms? What's really going on down there? And is it humanly possible to explain it so well that a nine-year-old child can understand it? Yes, it is, but only if you're Richard Feynman, Nobel Prize-winning physicist and probably the single greatest explainer in human history. Without oversimplifying, Richard Feynman clears away all the technical terminology and provides simple methods for visualizing the laws of physics.
