$$\frac{1}{T}=\beta=\frac{dS}{dE}=S'(E)$$. ##\beta## is amount of entropy increase by supply of unit internal energy. [EDIT] Velocity ##\frac{dx}{dt}##, Specific heat ##\frac{dE}{dT}## are similar in the sense that derivative matters. In a closed system with subsystems 1 and 2 $$E=E_1+E_2$$ E...

If the goal is to operate the reactor for an extended period with little or no additional fuel supplied from outside, the issue is not simply one of the breeding ratio; rather, it requires an integrated design that takes into account core burnup, neutron economy, and reactivity changes over the...

I think breeding ratio is controlled by blanket fuel rod allocation design. Keeping criticality for a long time is another issue. Fuel is extracted by reprocessing process. Consuming them during reactor operation seems impossible to achieve in reactor design.

Then [H^,A^]=0 and post #13 does not stand.

I still do not find what is A. A=P^2/2m ? If so ##[H,A]\neq 0## ?

I do not get what is A from your suggestion. More clear and direct explanation will be appreciated.

S-G Hamiltonian is proportional to Sz. [H,Sz]=0. Sz is conserved,I.e.,we get the same result in measurement performed in any future. What observable A is actually?

In the Klein paradox regime, the negative-energy solutions of the Dirac/Klein–Gordon equations should not be interpreted as particles in the usual single-particle quantum-mechanical sense. In quantum field theory, they are instead reinterpreted as positive-energy antiparticle states.　I wish it...

FYI experiment video of single photon Young double slit experiment by Hamamatsu Photonics in 1982. https://photonterrace.net/en/photon/duality/ [EDIT] New theory has to inherit all success of old theory and add systematic corrections for what old theory fails. In this sense QA could be "Does...

Light has been broadly considered as wave in CM. Newton considered it particles but wave nature of phenomena, interference, diffraction, Maxwell prediction of EM wave, classical optics, have had prevailed. In the begging of 20th century Einstein revived particle theory by photoelectric effect...

Each electron makes EM vector field individually. They superpose to be an observed EM vector.

Electrons are source of electric field. Gauss’s law describes it. When they are in motion magnetic field is also generated. Ampere’s law describes it. After we fully know them, we may investigate energy of fields. https://www.feynmanlectures.caltech.edu/II_04.html I Is a good reading to get the...

Very interesting observation. Does width of the slits, which affects Py uncertainty, affect on it ?

I remember I had learned in junior high that not wave amplitude itself but its square matters energy. How teachers are explaining the reason?

if you have no troubles in derivation of these formula which give values such and such in calculation, I am afraid that I have nothing more to help you.
