A Friend of the Welchs - TedTalks: Arthur Benjamin

Our friend, Art Benjamin went to high school with my wife, Rosanne, and several years ago we all re-connected out here in Los Angeles.

Below is Art's TedTalk from 2005, based on a similar act he regularly performs at The Magic Castle in Hollywood and for school kids around the world. Watch his "MathMagic" and be amazed. Even better, his books will show you how to do it yourself. (SMILE)
