Hey, I'm David, I stream computational and theoretical physics on Twitch sometimes. I also have a GitHub. I did a BSc math, BSc physics, MSc computational physics, and did a bunch of studying in lattice field theory in pursuit of a PhD.
A recent hobby project of mine was solving all of the problems in Structure and Interpretation of Computer Programs, which you can find here: /sicp/. Done with chapters 1-3, and it sparked some fun discussion.
You can also visit an archive of my old website.
