Oh, and incase anyone is interested, I should add the main reason I thought about this. I was viewing the home page, and saw a link to Roger Penrose's most current book, Road to Reality, and I thought "I've heard about that book, but wonder whether it's any good." Thus, I thought this forum would be a good idea to answer questions like that!

Anyway, again, thoughts and comments are most welcome.
