When I did my PhD in the late 80s we were simulating Kelvin-Helmholtz Instabilities on supercomputers with application to solar dynamics. It is very nice to see that they exist and behave like predicted. There are plenty of other plasma instabilities that were predicted at that time and have now been confimed by space probes.
