## teaching

Though teaching is currently not the #1 item in my job description, I continue to do some teaching as part of my work in the Physics Faculty.

In recent times this has been:

- Information Technology: actually a code name for an introduction to programming for beginners in Python
- Introduction to Databases: basics of processing of (mainly non-numeric) data, and an intro to relational databases and SQL, addressed to students of Neuroinformatics

In the more distant past I have taught practice classes in courses including undergraduate Math, Statistical Physics I, and Group Theory.

## side projects

Some stuff I've worked on recently:

- in-browser simulation of the Vicsek model of statistical physics, using WebGL2
- another statistical physics simulation, the Ising model in two dimensions, this one is implemented in pure Javascript and visualized with the Canvas2d API; a rewrite using WebGL2 would bring much better performance, though I must say this one is pretty good too
- a few others that are somewhat more in the eyecandy category:
- a playground of various in-browser animations
- self-avoiding lattice polymers of sorts
- Ulam's spiral, a pattern on a plane created by prime numbers — which are computed on the fly in the browser
- a crude demo of a few interacting particles flying around in a rectangular box; while it's fun to watch for a while, it usually soon succumbs to numerical instability.
