In case the author of the video reads this: I tried to watch it but after 2 minutes I just had to turn it off as I couldn’t handle that music anymore.

If I'd want to have background music I could play it myself, and it would match my choice.

A catchy intro is nice tho.

My mental image (fwiw) is that the push of an electron is able to push electrons both in immediate proximity and to electrons at a distance. So, that allows the relatively slow speed of moving electrons to produce nearly light speed changes in momentum of faraway electrons.

Earlier quoted context omitted.

it is impossible to deconvolve speed/direction in terms of momentum of the electron, so we simplified the idea with rotation speed. Ideally, the high charge atoms would be more cohesive as well as faster.

I'm out of my depth now, but wouldn't this have the same issues in a rotating frame of reference? Surely, if position/direction is conflated, then rotation is too, no? Or am I way off base?

You have to really look at the Heisenberg uncertainty relation.

Position cannot be sharply determined if we know direction (angular momentum). Speed is problematic too. The state of an electron (or electrons) in the atoms isn't an eigenstate of the velocity (or speed) operator, so no way to nail down the speed precisely.

That being said, we chose to abbreviate momentum with rotation speed for our visualization. Reality includes coherence of the shells. They must effectively rotate together to produce coherent momentum and force the other terminal.

" we propose the following animation: Electricity as surface-to-surface rotational gearing between electron-shells on atoms (see movie below). " That's not the mechanism for ordinary electrical conduction in metals. In my opinion the resulting visualization is very misleading. EDIT: I recommend the excellent Hyperphysics web site. http://hyperphysics.phy-astr.gsu.edu/hbase/electric/ohmmic.h

Why? Metals are addressed at the end of the video. Metals can be thought of in the same manner except with complex orbitals that host multi-polar contacts with neighboring atoms.

In the lab, electrical conduction transmits charge but does not transmit torque.

The proposed mechanism would transmit torque but not charge.

I think the poster is referring to the "electron gas as charge carrier" but personally I'm not exactly sure how things fit together.

Opposing anecdote: I liked the music. It made the video feel nostalgically educational, which is the feeling I get from the whole site.

Charge is symbolized by directional momentum of rotation here. Transmission of momentum indicates arc'ing of current.
