Einstein said, that you don't understand something, unless you can explain it to a six year old. Unfortunately Quantum Mechanics hasn't found any six year old smart enough yet ;-)

On the video, I like it (and he is correct, this is a model of a quantum system (like sticks and balls is a solar system) not an actual quantum system). An incandescent light bulb is a quantum system (and so much for the Equipartition Law ... it doesn't work with an incandescent light bulb ... because the non-continuous aspect of that phenomena, prevents it from being valid). This is expressed in Boltzmann statistics (classical) vs Fermi statistics and Bose statistics (both quantum). HS math is enough to understand models displaying each of these statistics.

Technically he speaks of "pilot waves" but that is non-standard QM, developed originally by DeBroglie, which was the immediate predecessor to "wave mechanics" of Schroedinger.

But people today are still trying to bring it back ... because we love to equate phenomena to mechanical things we can see/understand (hence mechanical models of the luminiferous Ether overturned by Relativity). Feynman said however, that anyone claiming to understand QM, didn't. Or maybe he as just being Socrates.

It is still a damn mystery, at least to megafauna like us humans, that an individual electron, can behave statistically, even if no other electron is present. The idea of a trajectory, like a moving car, is simply a megascopic simplification (if you accept QM).
