origami and math at MIT

http://mit150.mit.edu/open-house/activity/origami-and-math

Joel Lewis is a graduate student with the Department of Mathematics. He will present his talk on "Origami and Math". The first part of this talk will be a quick tour through the mathematics of origami, including brief mentions of connections to differential geometry, the art of angle trisection, and group theory.
The rest of the talk will consist of hands-on instruction in the construction of the Sonobe unit, a simple origami unit that can be used to create interesting and beautiful polyhedra.
