Sampling at negative temperature
Summary : Inspired by the definition of temperature in statistical mechanics and the possibility for it to be below zero, we try sampling LLaMA at T = − 0.001 T=-0.001 T = − 0.001 . The results are maximally weird.

The likely cheapest home-made Michelson interferometer
Lately, I’ve been really into 3D printing along with asking myself what we can do with this technology now that it’s become, well, a technology. (At least, in the “this is a thing that can now be used, is robust, and is generally accessible to many people” sense of technology.) The first thing to print on a 3D printer…
