Title: Magic with a ribbon, paperclips, rubber bands Abstract: What does it mean ‘to calculate’? We usually think of numbers or of formulas. Using just a ribbon, paper-clips, and rubber bands, we’ll explore a sequence of magic tricks, and before you know it, you’ll find yourself doing sophisticated `calculations’ on objects that aren’t numbers or formulas at all. The magic is robust, so you can later show it off to friends and family. 2016-02-10 @11:15 AM For more videos from the Simons Center for Geometry and Physics, please visit
