Claude pushes physics calc to 9 loops, physicist Cranmer: frame it as human-AI contribution
KyleCranmer · x · 2026-09-26
Claude reportedly pushed a theoretical physics calculation from the previous 8-loop record to 9 loops, working largely unsupervised for days, writing its own code, verifying via two independent methods, with 107,053 nonzero coefficients matching. Physicist Kyle Cranmer adds crucial context: Claude built on methods developed by his colleague Lance and used field tools and recent papers — a huge accomplishment, but one that should be framed as a combination of human and AI contributions, "not an exemplar of the bitter lesson."
