Brian Greene’s popular work on string theory, The Elegant Universe, lays out the potential “theory of everything” in understandable prose, and describes the evolution of physics that led up to its formulation.

It’s not a Hunger Games-type read, but if you’re not frightened away by the idea of curved space-time, supersymmetry, and 6 (or 7) tightly wrapped invisible dimensions, you’ll be fine. I majored in physics in college, so I approached The Elegant Universe with a decent base level of understanding, but I’d certainly never delved into string theory before. I had always just kind of imagined it as it sounds: a universe composed of very small vibrating strings. And it turns out, that’s pretty much what it is.
