When you crumple a piece of paper and throw it in the trash, ever think about the physics of how, exactly, that flat piece of material transforms into a little ball? How to describe it mathematically? It's a problem that's eluded scientists for millennia.  Now UMass Amherst physicists say they've solved it. Professor Benny Davidovitch and doctoral student Hunter King say they've used high-end math and physics to describe the mechanics of two distinct kinds of deformation: wrinkling and crumpling.  A subject that is familiar to most people and common in everyday life.
