UTM Math Club — The Diamond System

I gave a string workshop at the UTM Math Club. It was very experimental. I wanted to highlight the algorithmic aspect of string figures. We were going to do the first bit of inoli’s Diamonds System.

Geometric Reflections

Kaleidoscopes create wonderful geometric patterns.

They are both beautiful and thought provoking.

There is something pleasing to a mystic in such a land of mirrors. For a mystic is one who holds that two worlds are better than one. In the highest sense, indeed, all thought is reflection — Chesterton

In this talk, I outlined the mathematical theory of kaleidoscopes.

We introduced Coxeter geometries, and classified them in the plane.

Mathematics and Games (Kangaroo Math 2014)

On Sunday, March 23rd, 2014, I gave a talk to parents of kids writing the 2014 Kangaroo Math contest. The slides are available here: Kangaroo 2014 Slides. The content of the talk was a discussion of Tic-Tac-Toe in disguise, and a proof of the winning strategy for Nim.
