> this news is very cool 800 nanokelvins down to 100 nK! Brrr! [https://arxiv.org/abs/2109.12238 "Atomic sample preparation", pdf p. 16, and top of p. 3] Maybe it's soon time to plan updates to PARCS/ACES/SAGAS.

I don't have a PhD in physics and found this article pretty easy to follow - it's an accessible pop sci translation of a paper [1] that DOES require a PhD or at least a serious interest in physics to follow. [1] https://arxiv.org/pdf/2109.12238.pdf
