Arthur Benjamin Does TED TALK

One of my favorite acts to watch appearing on TED talk. The amazing mental feats Benjamin can accomplish are mind blowing...Even when you know how he does it!

Arthur was kind enough to allow me to re-publish his approach to performing the magic square in my upcoming book Mind Tapped 75 mental feats you can do with your mind!

Check out his book on the Secrets of Mental Math:
