Every once in a while, I dive into a topic in science for no reason other than that I find it interesting. This is how I learnt about Titan, laser-cooling, and random walks. This post is about the fou…

Consider this post the latest in a loosely defined series about atomic cooling techniques that I've been writing since June 2018. Atoms can't run a temperature, but things made up of atoms, l…
