(Fig.1) ↓ Illuminate metal with light → electric current = NO spin !
In this experiment, they illuminate some special metal with light, and it generates electric current induced by light. That's all they did. No spin here.
Though we cannot see unreal electron spin (= faster-than-light ! ), they hypothesize that light-inducing electric current includes spin.
No experiments can detect spin itself ! This experiment just measured electric current and voltage generated by circulary-polarized light ( this Figure.4 ).
Spin magnetic energy is too weak, Spin disagrees with all experiments such as Pauli principle and ferromagnet, though they want to use the name "spin".
(Fig.2) ↓Unseen, unconfirmed quark is meaningless as proton model.
Physicists argue that proton spin (= magnetism ) cannot be explained by only three quarks, which is inseparable, fractional-charge fiction.
So they start to say proton may include many other virtual sea quarks.
This is nonsense, unscientific, artificial model.
The present physics model is useless and meaningless, based on undetectable virtual particles.
(Fig.3) ↓ Schrödinger equation has NO exact solution in helium.
The latest quantum method of computing many-electron problem just repeats the old Schrödinger equation with No progress.
Schrödinger equation has NO exact solution except for one-electron hydrogen, all they can do is choose fake artificial solution.
We prove Schrödinger equation never gets exact solution of multi-electron atoms, no matter how many terms they use as approximate solution.
Artificial wavefunction sets of fake approximate solution is called "basis set", which is still used in this latest study ( this p.7 ). No progress. Useless.
(Fig.4) ↓ Quantum mechanics is a center of disaster.
This week news is spintronics, proton puzzle, Schrödinger equation.
All these physics are useless, waste of time and money, as I explained above.
