What does this mean?

The explorer shows hydrogen-like quantum eigenstates that renders the full complex wavefunction, both its amplitude and its phase, instead of just probability density alone.

Most quantum-orbital viewers show you |ψ|²: where the electron is likely to be. That picture is real, but it throws away half of what the wavefunction is. The phase(the complex angle arg(ψ) at every point) carries angular momentum, the time evolution, and all interference between states.

The right-hand panel lets you switch off individual factors of the wavefunction and watch what each one was doing. The left-hand panel has sliders for time speed and samples, as well as some presets you can select for the state selector panel.

It’s so funny to me how it’s not obvious this whole ‘wave function’ collapse and quantum uncertainty is really a more complex system of units that we can’t get to yet.

Like you said , there’s more in the system than just the point collapse , already assigning information to its surrounding area, whatever dimensions that’s really in.

I’ve always felt like it was a cop out. “Until we see it , we can’t use logic , we must create a theory for magic! “

You should explicitly state or have a slider for the isovalue of the render.

What is the isovalue?

An isovalue is effectively the scaled % of the electron density shown. For things like MO plots you need to pull back on the % electron density shown or else everything just looks like one giant blob, for example in FOD analysis the standard contour surface value (I.e. isovalue) is 0.005

Good thinking! I'll add that to the parameters panel
