Why the weak nuclear force is short range
The “range” of a force is a measure of the distance across which it can easily be effective. Some forces, including electric and magnetic forces and gravity, are long-range, able to cau…

LLMs aren't world models
I believe that language models aren’t world models. It’s a weak claim — I’m not saying they’re useless, or that we’re done milking them. It’s also a fuzzy-sounding claim — with its trillion weights, who can prove that there’s something an LLM isn't a model of? But I hope to make my claim clear and persuasive enough…
