An elegant universe

Book Review: Superforce - The Search for a Grand Unified Theory of Nature, by Paul Davies
This seems as good a day as any to post this review. I first read this book in the 1980s and wondered how much it would have dated. The short answer is, not much. It takes a little while to get going, with the first few chapters laying some basic groundwork, but once he's off, Davies writes clearly and convincingly, especially in the areas of gauge symmetry (including the Higgs), QCD and hidden dimensions, and provides a coherent argument that the idea that the entire universe, including its contents, may be made of nothing more than twists in spacetime. The subject of string theory is relegated to a postscript, not because it is insignificant, but because it was so new at the time the book was written (and some of the ideas in string theory dove-tail very well at a high level into the main part of the book). This is actually a great help, because more recent popular physics books I've written (I'm thinking of Brian Greene and Roger Penrose) do go into string theory in some depth but don't really provide any clarity. Still highly recommended.
