Math and especially 3-dimensional geometry are most fascinating subjects. On this page, I am trying to give an introduction to the areas which fascinate me that is suitable for non-mathematicians as well.

Geometry and Topology

The geometry and topology videos and links are ordered in terms of math background they require. The first video requires no math background, explains the idea of a regular tessellation in different dimensions and geometries and, inspired by Thurston, uses pictures rather than equations. The last video - Thurston's lecture - shows how amazing his intuition about geometry was and still uses no equation but is a bit harder to understand.
