Anthropic's science blog shows Claude pulling off 'Nine Loops' particle physics calculations

Anthropic published a new post on its science blog titled "Yes, Claude can do Nine Loops," showcasing Claude's ability to handle theoretical physics calculations.

In particle physics, scattering amplitudes predict how particles behave; they are notoriously hard to compute, so researchers work with layers of increasingly fine corrections called "loops" — each added loop improves precision but multiplies computation, and most calculations stop at two or three loops. According to the post, Claude can compute up to nine loops.

The tweet itself is a brief endorsement of the official Anthropic article, which carries the substance.
