The History of Navier–Stokeshttps://physics.nicholasbardy.com/lesson/navier-stokes-historyhttps://physics.nicholasbardy.com/lesson/navier-stokes-historyThe partner to lesson 01: the same equation, built again — this time by history. Five discoveries, two strangers in the name, a 152-year paradox, and a million-dollar question still open.
