26: The Theory of Everything: The Origin and Fate of the Universe, Stephen Hawking

Sometimes I wonder whether Hawking is a tremendous ass and whether his dry humour is a result of the difficulty he has in communicating.

In any case, this book could have done with some more editing. It's a popular scientific (very popular, no equation of any kind, no diagrams, no graphs) series of lectures (published before as The Cambridge Lectures: Life Works), and as a written work it's unfortunately repetitive. Not Hawking's best book.
