Just picked up a hard cover, first edition copy of this timeless book at my local library sale for a $1. Hot damn.
While some of what is in this book may be bunk if string theory proves true or if the Large Hadron Collider throws everything for a loop, it is still one of the most important science books in history. Dr. Hawking is an incredibly brilliant mind who managed to write a user friendly guide to the cosmos. You may have to reread a few paragraphs, but this will enlighten anyone who gives it a shot.
Dr. Hawking is a freaking rock star.
