Elegant universe is a great book. String theory for dummies.
We currently live and interact in four dimensions - 3 spatial, and one temporal. String theory requires additional dimensions to work, and the math comes out to either ten dimensions or 24 (don't ask me how, I have no idea). The four we currently understand, and then (supposedly) six more that we pass through without knowing.
Owwww....my brain.....
