On May 18, IPAM was pleased to host a public lecture by Tadashi Tokieda entitled “A World from a Sheet of Paper.”  By folding, stacking, crumpling, and tearing paper, he demonstrated a variety of phenomena in physics and geometry such as elasticity.  His table-top demonstrations captivated the audience which included UCLA students and professors, as well as families with children.  Tokieda is the Director of Studies in Mathematics at Trinity Hall, Cambridge, and the Poincaré Visiting Professor in the Department of Mathematics, Stanford.  He is a true polymath: a painter, a classical philologist, and an applied mathematician.
