When you were at high school, math was probably an uninspiring string of algebra you had to crunch through. Get to the cutting edge of computational fluid dynamics, though, and it all starts to look a hell of a lot more pretty.
These images represent incredibly complex fluid flows, and were generated suing supercomputers by researchers at the Laboratory for Computational Science and Engineering, University of Minnesota. From the top, these images show off examples of the Rayleigh-Taylor instability, the Kelvin-Helmholtz instability, and finally some good ol' fashioned turbulence.
