<h2>Spectral Simulation of the Instability</h2>

<p>
What you are looking at is a simulation of the Kelvin-Helmholtz Instability. It was first characterized in 1868,
and occurs when there are two fluids with relative motion, called shear, between them. This simulation was done in
<a href="http://dedalus-project.org/" target="_blank">Dedalus, an open-source differential equations solver.</a> Each of the boxes began with the same configuration, but a single parameter,
called the Reynolds Number, was changed for each one. As you can see, the higher the Reynolds number, the more complex the structure
becomes. This is because the diffusion of the fluid becomes very small, and can't smear out the structure. The second row shows
vorticity, which is a measure of the "spin" of the fluid, also called the motion's "Curl."
