Last week, OpenAI stunned the world by claiming that its most advanced artificial-intelligence model had solved a Millennium Prize Problem: one of just a handful of notoriously tricky mathematical conundrums that each come with a US$1-million prize. The AI solution proved mathematically that there are instances in which the Navier'Stokes equations ' famous, nineteenth-century formulae that model how fluids flow ' produce a 'singularity', predicting physically impossible infinite speeds for gases or liquids. The news has opened up discussions about the blossoming mathematical abilities of AI, whether AI models are soaking up the unpublished work being done by others, who deserves credit and more. But there's another question, too: what does this mean for the study of fluid flow' The solution posted by OpenAI, which is based in San Francisco, California, explores a situation in which a vortex of fluid stretches out, becoming very long and very thin. George Karniadakis, an applied...
