For a while I've thought that having a website to share some stuff useful to people including me would be a good idea, so here it is.
My primary interests are tinkering, math, physics, movies, taekwondo, parkour, and art. I do the first three professionally now, and have posted some of my old (non-professional) pet projects here.
I also do projects in math. These days my main interests are in topology, algebra, and theoretical condensed matter physics, as well as pretty much any math related to the name "Witten." As one can probably figure out, I also posted some art and a list of my favorite movies.
