This is the best word picture of the formation of #supernovas and #neutronstars

I especially like the concept of using "cold atom experiments as analog #quantum #computers" to study the #vortices which occur in ultra-cold #gases below the Fermi temperature.

Sounds a little like trying to model the earth's atmosphere when thermodynamic properties are goosed by #climatechange

"The #winglet converts some of the otherwise-wasted energy in the wingtip vortex to an apparent thrust. (…)

Another potential benefit of winglets is that they reduce the intensity of wake #vortices. Those trail behind the plane and pose a hazard to other #aircraft."

A possible game changer for next generation microelectronics

Scientists at the U.S. Department of Energy’s (#DOE) Argonne National Laboratory want to replace the bar #magnets with tiny magnetic #vortices. As tiny as billionths of a meter, these vortices are called #skyrmions, which form in certain magnetic materials.
