Khan Academy

While watching 60 minutes tonight, I learned about Khan Academy.
www.khanacademy.org

This is a wonderfully fun and informative website. The creator, Mr.Khan is dedicated to providing a free world class education to the world.

To find out more, visit 60 Minutes, or better yet, just go to khanacademy.org.

He even has a section devoted to brainteasers!
