Physics of Toys

Tadashi Tokieda, Cambridge University

Abstract: Look carefully at many toys and you will find that they rely on interesting physics. I will show a number of simple toys that have intrigued me, both for the fun they bring and for the complex physical and mathematical principles underlying them. The main theme is the effects of friction and of nonholonomic constraints. I hope that the lecture will be nontrivial for seasoned scientists and entertaining for young children.ANNUAL HOLIDAY PARTY: 4:30 P.M., 13thFloor Common
