Excellent intro to "Loop Quantum Gravity" theory. What's that, you ask? Well, I'm not a science guy, but I must say that the author does a wonderful job of relating the history of physics - beginning with the ancient Greeks, culminating in discussions about space/time quantas. Just a handful of equations, but with references to more technical publications. Highly recommended.
