Title: Silly book
Review: There is nothing to be gained from this silly book if you have already read layman introductions to relativity and quantum mechanics. I got a chuckle reading the final chapter 'Prospects' where the author admits string theorists make wild assumptions about the nature of spacetime at the planck length and that present day mathematics are woefully inadequate to tackle the various problems. So what are you as a layman left with? Nothing, because Greene admits the underlying principles behind M-Theory (the theory formerly known as string theory) are unknown. Don't be fooled by all the wonderful reviews. Most are buying this book as a ornament mean't to impress other people.
