The first 2/3 of this book was a 3 star. Randall was all over the place with analogies and subject matter. It was hard to keep track of the points she was trying to make and for my desires it was a bit too light on the physics I was looking for. The last 1/3 completely made up for it. Good material on sub-atomic particles, the LHC, expansion of the universe, dark matter and a bit of string theory. Mostly over my head but I did feel my hair move in the breeze.

3.5 stars rounded down because too much of the book was a bit scattered.
