What OpenAI Actually Did to Navier-Stokes (EP 58)
What does it mean to solve an equation that describes almost every fluid around us, from the air over a wing to the water swirling down a drain?
In Episode 58 of From First Principles, Lester Nare and Krishna Choudhary build the Navier-Stokes equations from the ground up before digging into OpenAI’s claimed breakthrough and the debate surrounding it.
