I have posted 3 videos on this page.

The first one is approximately 3 minutes long. It’s called “A Bug Goes off on a Tangent.” It’s about an insect that can’t climb to the top of the white board, but wants to know the distance to the top of the white board. He discovers similar triangles. It was inspired by participation by elementary school students in a local mathematics club. Enjoy!

The second video is a 9 minute video. Hopefully it will encourage you to have a look at the paper:

A Parity Theorem for Drawings of Complete and Complete Bipartite Graphs, D. McQuillan and R.B. Richter, American Mathematical Monthly, Vol. 117, No.3, March 2010. I’m reworking this one.

This last video is a hilarious performance by Ján Mináč and Leslie Hallock at the University of Western Ontario. It answers an important question regarding the sum of two algebraic numbers. It also answers questions regarding the relative power of the chalk and the sword!
