A critique of recent semi-classical spin-half quantum plasma theories
... and the tiny spin-dependent correction to the “orbital energy” contributed by the high n term is clearly an insignificant effect. Any semi-classical approach must require n ≫ 1 and thus cannot possibly account for the spin quantum number σ or effects arising from it. Thus, the quantum [Pauli equatio ...

What we perceive in physical science as space time is some part of more general reality that Motion would reconstruct most easy, because what we need to get Motion we already have in appearance of quantum mechanics.
