Category Archives: Geometry and Topology Today

Geometry and Topology Today is Shea Vela-Vick’s and my attempt to create a television channel where we interview famous (and maybe not so famous) mathematicians about their latest theorems. The goal is to keep the discussion at the high school/general interest level (read: young people can watch!).
