What else can we do to manipulate the phase of the wavefunction of other particles, and what else can we achieve besides tuning orbital angular momentum?
It's a lack of empathy. He is unable to place himself in my shoes and see why his actions are detrimental. @obe what are some mental illnesses characterized by a lack of empathy?
Because they could be imagined to give a superficial gloss of respectability to papers either unpublished or published in faux journals they actually end up functioning as a channel marker for off-the-beaten path ideas.
That is, mostly junk.
Of course, claiming to predict or explain absolutely everything except the whether is another subtle hint.
If you take it as the equation of motion for a massive spin-1 field which just...is massive, then the "Lorenz gauge" is not a gauge choice, but just an equation of motion/constraint that has to be implemented
If the mass of the spin-1 field is generated by an Abelian (or Stueckelberg) Higgs mechanism, then this is indeed a kind of gauge choice, and the Stueckelberg action was gauge invariant (albeit under $\mathbb{R}$, not $\mathrm{U}(1)$)
@0celo7 Ah, "separate" was the wrong word. You can differentiate the E-L equation once more to make two of the three terms vanish, and what's left is the Lorenz gauge.
Plugging that back into the original equation, you get the 4-vector version of the K-G equation.
Small question: If I have a chemical reaction that occur when I mix reagents A and B together without any extra heat or light input, is the reason in the physical scale why the reaction happens using conservation of energy is that the electronic energy of the reacting molecules can become lower after the reaction?
That is, one in chemistry will say the energy needed for the reaction is chemical energy, but besides the electronic energy of the electrons in the molecules, what other energy types are involved in chemical energy?
> It was a big deal last year when Konev and Lisitsa used a SAT-solver to prove that there’s always a subsequence with discrepancy at least 3; Tao’s result now improves on that bound by ∞.
"Bomb hoax" implies malicious intent methinks... but I think we'd agree. Someone in my middle school got arrested/homeland security got involved, because he made an electromagnet that looked an awful lot like a pipe bomb (~2005?).

For the past few days I have noticed that for no reason that my reputation is decreasing. I mean to say that when I am logging out one day, I see a certain reputation and when I log in the next day, I see my reputation has decreased by about 20 points or so and in my reputation change bar, there ...
The Einstein–de Haas effect, if I understand it correctly, demonstrates a deep relationship between the intrinsic angular momentum (spin) and the magnetic moment of a particle; For this reason when a cylindrical ferromagnetic material
is placed in a external magnetic field, it will begin to spin ...
(missed question 1) Is chemical energy fundamentally just electrostatics between electrons and nuclei in the molecules or between molecules, or is there more to that?
The reason to double check on this understanding is to understand how the energetics are contributed by physics phnomenon. Unless I have overlooked something about electronic states, isn't the energy from a chemical reactions is due to the electrons in the orbitals being able to be achieved a loser energy by gaining strong columbic attraction to the nuclei of the atoms in the molecules as the chemical reaction rearrange the m…
hypothetically speaking if I asked a question, it got answered and then for some reason I wanted to delete that question, would it be possible to do so?
@AngusTheMan you would have to get a mod involved and have a good reason; though they can also anonymize the question if you just want your name off it
so a guy told me objects cannot move if space is not quantized his "reasoning": without quantization there would be an infinite number of positions between any distance, and we can never reach infinity, so objects cannot move any distance
