As the tag line suggests, this blog is about science, mathematics, and computing. I spend my time in my day job as a mathematician, or a computer scientist, or an engineer, depending on the situation, preferably in that order, but usually in reverse. I also love teaching, and so I reserve the right to fall into pedagogical rants from time to time.
Subject matter typically deals with my day-to-day encounters with mathematical or scientific ideas that I find beautiful, valuable, interesting, amusing, or (less often) infuriating.
I am also a fan of free software. In the rare cases when my interest in a problem survives long enough to yield some software that others might find enjoyable, useful, or otherwise interesting, I try to make it available here.
