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.
I have some book notes, where I'm solving all the problems in the book SICP, and am learning formal verification through studying Metamath.
You can also visit an archive of my old website.
