What's the equation that appears in the background of some scenes?

Looks familiar... hmm...

At 1:36 there is the Schrodinger equation applied to the hydrogen atom:

\left[ -\frac{\hbar^2}{2m}\nabla^2 - \frac{e^2}{r} \right]\psi(\mathbf{r})=E \psi(\mathbf{r})

Note 1: It is the equation for relative motion; notice the reduced mass \mu

Note 2: It is written in units where 2 \pi \rightarrow 1 (no bar on the "h")

I'm unfamiliar with those units...

They're Hollywoodian units.

Most likely, the graphics designer/editor thought the bar was a stylistic addition with no mathematical relevance.
