BootLoops puts Claude to work across 18 scientific fields

@neuronium_ai @neuronium_ai

BootLoops, an open-source tool described by Anthropic visiting researcher and physicist Schwartz, uses Claude for precise scientific calculations across fields. In three months, Schwartz and 19 co-authors prepared 36 manuscripts spanning 18 disciplines. The work points to a practical role for AI in research: not replacing scientists, but helping them explore calculations and connections that can become useful when experts choose the right questions.

Finding links across fields

Schwartz’s case for BootLoops rests on the gaps between established disciplines. He compares human knowledge to a “convex hull”: fields advance along their own paths, leaving the spaces between them less explored. A lab might spend 20 years studying one group of genes with one method without examining nearby genes or alternative approaches. BootLoops is meant to help search those boundaries.

The early projects ranged from physics to ecology and language. In particle physics, Claude computed 30 integrals with BootLoops: 15 matched known results, while 15 had not been calculated before. In ecology, it solved an equation from neutral biodiversity theory that had resisted calculation at that scale for 20 years. Applying the result to data from Barro Colorado Island in the Panama Canal, researchers found that tree species composition changed 4.5 times faster than the theory allowed. Ecologist James O’Dwyer helped turn that observation into an improved predictive model.

Other projects included an analysis of 5.7 billion pairs of mutations from the 1000 Genomes Project, which found evidence of gene conversion, and tools for economic research and linguistics:

An editor for economics data checked 4,452 replication packages; the work was published as an NBER working paper.
A database recorded word stress across 6,072 languages, built with three linguists.

Speed changes the training question

Schwartz argues that AI is already changing how researchers plan work. If a model can complete a calculation overnight, he asks, what is the case for applying for a three-year grant to do it?

That pressure also reaches graduate training. Schwartz once considered “Python for engineers” an essential course; now he thinks Claude can handle the tasks it teaches. He also expects AI to take on building machine-learning models for studying physical phenomena, reducing the advantage of knowing neural-network methods in depth when Claude can implement current techniques on request.

Faster calculations still need scientists

The project’s limits complicate any claim that AI can do research on its own. Schwartz says Claude can declare victory before a task is complete, misjudge how long work will take, and brute-force calculations instead of finding more elegant solutions. Automated checks are not fully reliable, and conclusions can be wrong even when the calculations are correct. He also notes the projects’ high computing and token costs.

I think the most important result here is not the claim that Claude can replace scientific training. It is that the tool can make some calculations cheap enough to attempt, while the choice of question and judgment of the result remain human work. Schwartz says the research gained scientific value when specialists directed it. The unresolved tension is whether faster computation will broaden scientific inquiry—or simply make researchers reach familiar questions sooner.
