OpenAI claimed earlier this month that one of its internal models had proved that the Navier-Stokes equations, which are used to model the motions of fluids, break down and yield nonsensical answers in certain scenarios. Justin Beroz, CEO of ReynKo, an engineering company that specializes in turbulence, says the equations can be thought of as “essentially Newton’s second law, applied to a little fluid parcel.” Regardless of whether OpenAI can actually take the credit for solving the problem, the notion that an artificial intelligence has apparently succeeded where humans have, for so long, failed is earth-shattering for mathematicians. That isn’t the case for engineers, however, say several experts working in fluid dynamics. OpenAI’s claimed proof of the Navier-Stokes problem is a mathematical tour de force, but any real-world applications may be years away—if they ever arrive at all.
