Knowledge base

Welcome to my knowledge base!

Over the years, I’ve learned a lot of physics, mathematics, and computing. These are vast, difficult subjects, and I’ve spent many hours of my life trying to make sense of obscure, poorly explained concepts. To help me remember what I learn, I write notes in LaTeX.

This knowledge base is based on my notes, and is freely available to anyone who needs it. I hope it helps you in your studies or work.

Keep in mind that I’m only human, so there are probably mistakes here. I take no responsibility for any injuries. If you’re doing something important, you should check things yourself!
