Mathematics Seminar Series - Spring 2007

From Kepler's Echinus to Rubik's Stellated Dodecahedron

Abstract: This talk starts with Kepler's additions to the Greeks' list of the five Platonic polyhedra and ends with some open questions about a puzzle that's harder to build than to solve. Along the way we'll look at some models in paper, wire, cloth and software. Undergraduates welcome.


The presentations cover a large variety of topics and are intended for a general math audience. The seminar is organized by Prof. Alfred Noël and we usually meet Monday afternoons, from 2:30 pm to 4:00 pm.
