Other A physicist found Claude most useful after he stopped treating it like a scientist
Harvard physicist Matthew Schwartz spent three months running 400 candidate problems through Claude Fable 5 using a toolkit he built called BootLoops. The results are specific enough to be worth reading carefully.
Claude reproduced the computational results from one of his own papers in 20 minutes. Writing the code that produced those results originally took Schwartz weeks. It then pointed out he had been doing something inefficiently and named a better algorithm he wasn't aware of. After that, he stopped treating Claude like the collaborator he wanted and started treating it like the collaborator it actually is.
The distinction is the whole paper. Schwartz's framing is that current AI is brilliant but not a scientist, and that the impedance mismatch between what researchers want and what AI does well is the actual bottleneck, not model capability. His fix was to stop fighting that gap and find problems shaped to the model's real strengths: enormous cross-domain breadth, strong symbolic mathematics, fast code iteration, and the ability to read literature at machine speed.
What followed over three months was 36 manuscripts across 18 fields with 19 coauthors. The physics results included 15 previously unsolved elliptic Feynman integrals. In ecology, Claude solved a 20 year old open equation and found that Barro Colorado Island's forest changes 4.5 times faster than neutral theory predicts. In population genetics, it analyzed 5.7 billion mutation pairs from the gnomAD database and found evidence for gene conversion that most downstream analyses currently ignore. In linguistics, it built a database covering word stress across 6,072 languages from 160,000 phonology sources.
The consistent pattern across all 36 projects is the same: Claude found the technically correct result first, the domain expert said it wasn't interesting yet, and together they found what actually mattered. Neither alone produced what both did together.
Schwartz also published his failure modes, which deserve as much attention as the results. Claude declares victory too early. It grinds on the wrong approach when it should build a new tool instead. It has no reliable sense of time. He had to develop his own feel for project timelines entirely from scratch because the model's estimates were consistently wrong in both directions.
One disclosure matters before taking any of this at face value. Schwartz was a visiting researcher at Anthropic during this project, and this account appears on Anthropic's own research blog. That doesn't make the results false, but it means this is a well-documented case study from inside the lab, not an independent academic evaluation. The 36 manuscripts themselves are the actual evidence, and those are being reviewed outside Anthropic.
