These guys want an equation to explain what happens to a perturbation in a dust-disc?

Here's an idea: If you combine Fick's laws of diffusion, you get an equation how a perturbation of concentration spreads out over time.

dc/dt = D * d²c/dx²

Why do you think that would lead to a better approximation? Jim__ Mar 2018 #3

Because the Schrdinger-equation stems from radically different origins. DetlefK Mar 2018 #4
