Everything You Always Wanted to Know About Decaying Turbulence: But Were Afraid to Ask

Gently stir a fluid in a large box sitting still. This talk is about the behavior of turbulence that is generated. We report results of large numerical simulations of the Navier-Stokes equations in a triply periodic box---and compare the outcomes with classical work, which was begun in the 1940s, and with Alexander Migdal's theory of the 2020s.
