Standard Model 4: Quantum Physics

Azimuth 2026-03-06

This is a crash course on the basic principles of quantum physics! In a self-contained way, I explain quantum states and the basic rule for computing probabilities.

It was a fun challenge stripping down everything to the bare minimum. Of course there is much more to say, but I was focused on leaving out everything that was not absolutely essential—to get to the real core of things.

There’s a huge fog of confusion surrounding most popular introductions to quantum mechanics, and I wanted to avoid all that. To do this, we have to use language in a pretty careful way.
