Here's a book I have to put on my reading list...

Dr. Lisa Randall, of Harvard University, is one of the world's current experts on particle physics, string theory, and cosmology. In view of some of my posts below regarding dimensionality in our universe, her book Warped Passages: Unraveling the Mysteries of the Universe's Hidden Dimensions looks like a must read.

Thanks to one of my colleagues at work for making me aware of this...
