@oreillymedia: An external research team used Anthropic's Claude to crack the Jacobian Conjecture, an algebraic geometry problem that had stumped mathematicians for 87 years, and professional mathematicians later verified the proof was correct. As Christina Stathopoulos explains, Claude found an example where three different starting points all led to the same result, disproving the long-held assumption that you could always work backwards from an answer to find the original input.
