Cool recap on physics. I'd say it's a little above the layman's level for a quick, full understanding. On the other hand, it's pretty simple for someone w/ a physics/engineering background. BUT, it makes you think about some of the cool fundamental shit going down - minus the fact that this is like 50 years old. For example, it'd be nice if it touched on the Higgs boson, etc.

Feynman has a talent for describing physics. Early on, he relies on formulas more often than necessary I think, but that subsides w/ more complex concepts. Good, unbiased approach.
