The book is The Cosmic Landscape by Leonard Susskind.
Amazon
Usually I have to trudge along informational books, but the author made the subject really enjoyable. Apart from not only enjoying the book, it also included a link to a brilliant site, that the author had written an article to.
The site is http://www.edge.org
With all the campaigning and trash that's been splashed around digg.com, I now have a new source for scientific breakthroughs and hypotheses.
Just thought I'd like to share.
EDIT: The book is amazing and I recommend it for everyone. One of the things my grandfather told me to stay away from was the section on string-theory, which is located towards the end of the book. The rest of the book focuses on common held beliefs and how they were able to reach the conclusions.
