AI solved one of math's hardest problems. Humanity learned nothing (so far)
Tuesday, September 22, 2026
OpenAI's AI system found a solution to the Navier-Stokes equations, one of mathematics' unsolved millennium problems. Mathematicians interviewed by the outlet stated the solution does not provide new insights into the mathematical principles underlying the equations. The Navier-Stokes equations describe fluid motion and have resisted analytical proof for over a century, with the Clay Mathematics Institute offering a one-million-dollar prize for a solution.
