This post is from one of several previous incarnations of this site and probably doesn’t quite fit the current format. In a former life this was a group blog and a tumblelog before it became a static jekyll site. If anything looks broken or is worded oddly that could be why. Pardon the dust.
I was learning a bit of maths recently and thought of trying out Mathematica, only to find when I looked into it that it costs about a grand. Maybe this would be enough for what I wanted.
