#### General interest talks / Fun talks

• Random matrices and the Riemann zeros,
Talk given in the Stellenbosch postgraduate seminar, 5 March 2009.

#### Older physics publications

I enjoy teaching. I am interested in all the various teaching methods, from "chalk and talk" to using technology. Here are some videos of me explaining a limit problem from James Stewart's Calculus, or the memo for a tutorial test. Here is a sample exam I set for Multivariable Calculus.

I try to keep classes interesting by adding bits and bobs of enrichment. For instance, illustrating the difference betweeen rational and irrational numbers by going over Pyhtagoras' original proof of the irrationality of √2, or by learning about the difference between equal temperament and Pythagorean tuning in music. Or, learning about conic sections using Mathematica demonstrations.

Students studying math also need some inspiration. For instance, a speech by Jim Simons, or by Tim Gowers. Or that being a mathematician was rated the best job in America in 2009!

Current PhD students
• Gerrit Goosen. Gerrit's project is to implement a string-net (in the sense of Kirillov) version of the isomorphism (due to Balsam-Kirllov and Turaev-Virelizier) between the Reshetikhin-Turaev and Turaev-Viro-Barrett TQFTs.
