### THE DIFFERENCE BETWEEN sCIENCE (INTELLECT) AND TECHNOLOGY (INTELLIGENCE):

MATHEMATICIANS SECOND-GUESS CENTURIES-OLD FLUID EQUATIONS (KEVIN HARTNETT, 01.07.18, Quanta)

THE NAVIER-STOKES EQUATIONS capture in a few succinct terms one of the most ubiquitous features of the physical world: the flow of fluids. The equations, which date to the 1820s, are today used to model everything from ocean currents to turbulence in the wake of an airplane to the flow of blood in the heart.While physicists consider the equations to be as reliable as a hammer, mathematicians eye them warily. To a mathematician, it means little that the equations appear to work. They want proof that the equations are unfailing: that no matter the fluid, and no matter how far into the future you forecast its flow, the mathematics of the equations will still hold.
