# Illustrating Geometry (and Topology)

(GMT)

Saul Schleimer (University of Warwick)

According to PoincarĂ©, "geometry is the art of reasoning well from badly drawn figures" [1895]. In this talk I will give an informal discussion of some famous attempts to draw mathematical figures: some more, and some less, badly drawn. I will finish by discussing some of my own work (with Henry Segerman) in this direction, attempting to use computer graphics, interactive web apps, and 3D printing to illustrate mathematics.

A recording of the talk is available here: https://www.youtube.com/watch?v=iaI6lsqL-_0.
