Large Language Models -- A Physicist's Perspective
In December I started experimenting with using Claude Code for physics calculations, and was playing with different methods for verifying their output. The buzz around Claude Code was huge, but I didn’t see many physicists using it, until I...
Getting inside Claude's head
A conversation on claude.ai, 26–27 February 2026. With some cutting out for brevity (by Claude).
What follows started as curiosity about Claude’s “learn” button, and when it couldn’t explain how that mode actually works, I started p...
Teaching an AI to Do Physics by Wiping Its Memory
“Good luck to future me” was Claude’s farewell message before I flashy-thinged its memory—Men in Black style—for the fourth time. I’d asked if it had any final words—and it did. Notes for a future self that wouldn’t remember writing them....
We are in the era of Science Slop
Created with irony by Sora
It feels like there’s been a sea change over the last six months. Most of my colleagues now use LLMs regularly— for bouncing around ideas, proofreading, even doing calculations. A number of high-profile examples...
No, classical spacetime can’t produce entanglement
A number of proposals for testing the quantum nature of spacetime (Bose et al.; Marletto–Vedral) aim to do so by producing gravitationally mediated entanglement (GME) between two masses. The logic is simple: creating entanglement between di...
