Plenty of familiar equations that are explained just enough that you can get a sense of their use. Excellent visual style and I do like the navigation. Requests: Ability to tap on things like Boltzmann constant to get values and a brief explanation of where it comes from. Maybe a little calculator using the equations? Would be great to very quickly tap in values and get a rough result. Animations in the visual style. Missing Navier stokes, viscosity, viscoelastic moduli, etc.
