VISUALIZING HYPERBOLIC HONEYCOMBS
Dr. Henry Segerman (Oklahoma State University)
We can describe any of the five platonic solids with only two numbers: the number, p, of sides on each face, and the number, q, of those faces that meet at each vertex. The pair {p,q} is called the Schläfli symbol for the polyhedron. By changing p and q, we can also describe regular tilings of the euclidean and hyperbolic planes, and by extending to three numbers, {p,q,r}, we can describe regular tilings of three-dimensional spaces. I'll talk about a project Roice Nelson and I worked on, trying to draw some sort of picture of every length-three Schläfli symbol, from {3,3,3} to {∞,∞,∞}.
2:00-2:30 PM
SOAP FILMS SUSPENDED ON KNOTS
Dr. Carlo Sequin (UC Berkeley)
Suppose you dip a wire model of a mathematical knot, such as a trefoil of a Figure-8 knot, into a soap solution – what kind of surface would the soap film form? Results will be shown for various interlinked loops and knots in the form of plastic models made on inexpensive 3D-printers. The talk will be followed by a display of many such models, with the challenge to identify the knots that were used to form these surfaces.
2:45-3:15 PM

Stage Show featuring Mark Mitton, Magician
Mark Mitton is a professional magician who is fascinated by using magic to better understand how we see the world. In addition to performing at private and corporate events all over the world, and creating magic for film, television, the Broadway stage, and Cirque du Soleil, Mitton tirelessly explores the theme of ‘Misdirection’ from an interdisciplinary standpoint. He regularly presents on ‘Perception’ at universities and conferences in North America and Europe, including the Association for the Scientific Study of Consciousness, and has lectured with the late Nobel laureate Dr. Gerald Edelman of The Neurosciences Institute. Mitton has performed at festivals in Europe and Asia; at the Olympic Games; in war-torn Liberia; in hospital wards around New York City; and in a Mexican orphanage. His magical hands are featured in a They Might Be Giants video.
