Warped Passages

A very good layman's introduction to notions of modern mathematical physics, quantum mechanics, cosmology, and the quest for a unified field theory. I enjoyed reading it very much.
My only quibble with the book was that it lacked the mathematical detail I would have liked. However, I am probably an atypical reader. I have a B.S. in Mathematics from MIT and M.S. and M.A. degrees in Math from my 10+ years in grad school studying math. Still, a Suggestions for Further Reading section would have been really helpful for those interested in learning more technical detail.
