The Fields medalists’ objections to AI will not age well. Yes, the true value of mathematics lies in understanding. But what counts as mathematical understanding, and indeed even a valid proof, evolves. First came geometric construction and thereafter symbolic calculation, 34.3K views · 236 likes · 36 reposts · 43 replies Open on X →

Would be good for OpenAI to find our with certainty how Alpoge/Buckmaster's data was used (in any way shape or form, de-idenfitied and all). "Unlikely", without quantification, sounds like legalese, and "cannot rule out" is weak coming from an organization that just solved a 10.4K views · 157 likes · 10 reposts · 21 replies Open on X →

We congratulate Levent Alpöge and Tristan Buckmaster on their remarkable mathematical work. We (the researchers and the agents) did not see any of their work through any means until they released it publicly — in particular, no specific user data was accessed in order to solve 8.2M views · 21.8K likes · 2K reposts · 1.5K replies Open on X →

Checking that a major mathematical proof is correct can take years. Formalization—converting the mathematical reasoning into a form computer proof assistants like Lean can verify—can help. Last month, Claude completed the first formalized proof of Fermat’s Last Theorem, one of h

Quantum field theory textbooks have been lying to you or have left you confused. For a typical passage like the following from Peskin&Schroeder - what does it mean to do a change of variables on an ill-defined path integral? For perturbative QFT, my paper resolves this issue: 🧵 h
