Welcome to the online companion to The Complete Idiot’s Guide to String Theory, now available in bookstores, both online and in the physical universe. You can even download the audiobook in iTunes now.

This site offers errata, links, and other goodies. I hope you’re enjoying the book and find it useful. Here's an opportunity to learn more!

The book is designed for anyone who feels intimidated by physics. Even experts who’ve read the book tell me they found it helpful—it lays out the principles that most textbooks gloss over. Despite what the title might imply, the book is about far more than string theory:

1. •Brings you up to speed on Einstein’s theories of relativity and quantum theory
   

2. •Explains why unifying them is so important—
   and so challenging
   

3. •Demystifies black holes and the big bang
   

4. •Describes not just string theory but also its main alternatives, such as loop quantum gravity and “buckyspace”
   

5. •Outlines experiments that are planned or ongoing to test these theories, notably the Large Hadron Collider
   

6. •Sorts out the claims and counterclaims in the public controversy over string theory
