Dr. Dirk Huylebrouck Unusual methods of mathematical visualisation

When proposing visualizations for mathematics, the usual media are computer drawings or 3D models. There is a rational for more surprising visualization methods, as good teaching partially relies on a surprise effect. The author proposes a tryout of 3 unusual visualization methods: visualizing Pappus theorem using laser beamers (based upon a setup made by two students, Annelore Vercouter and Leila Lavens), or Pascal s generalization for conic sections, visualizing transformations of polyhedral objects using black light, and visualizing mathematics through gastronomy (called an art in Belgium and France). Examples will be demonstrated live, using, respectively smoke, gloves and ice cream. Dr. Dirk Huylebrouck is from The StLucas School of Architecture in Brussels, Belgium.
