The motion of fluids seems simple, but the equations behind it are the subject of one of the most famous puzzles in mathematics. That puzzle now appears solved, thanks to AI, even as the feat came with a flood of controversy.<\/p>\n
OpenAI announced September 8 a solution to the Navier\u2013Stokes existence and smoothness problem, which is so monumental that a $1 million prize has been offered for its resolution. \u201cIt\u2019s one of the guiding problems for the field. It is a huge deal to know the answer,\u201d says mathematician Dallas Albritton of the University of Wisconsin\u2013Madison, who was not involved with the new work.<\/p>\n
