I've done a couple edits in my time, of various kinds – transcribing old sources, tweaking for consistency, disambiguating, reverting some vandalism, that sort of thing. Bit of a junior Wikipedian in that sense; as in life I like to do a little bit of everything.
My MPHys (2022) was Computational Physics in which I started (and still continue) developing Python units calculator noether as part of it. My thesis was on "Two-dimensional approximation of rotational locomotion in a dry granular system", and for absolutely no good reason at all I developed a bespoke generic simulation dispatch system for it.
