comment Plants and Quantum Mechanics!
@TAbraham: Just as ChrisWhite has pointed out, the path integral is but one of many representations of quantum mechanics equivalent to each other. You can certainly translate any one description into another. The only methodological difference is one specific problem is more amenable to comprehend and solve in one representation than the other. It all depends on the specificity of the problem.

comment Proving susceptibility in Lorentz Model satisy Kramers-Kronig relations
@Vesnog: The relation I refer to in my answer is of course the KK relation, because that is the objective of this exercise, is it not? Also $\gamma$ should take on the negative (not positive, please read carefully) sign if KK is to hold, as I have clearly stated in my answer. The first thing you ought to do then is to study the Cauchy Integral Theorem if you have not done so en.wikipedia.org/wiki/Cauchy%27s_integral_formula. It will also be more efficient if you can make your questions more to the point since it is hard to discern what you are trying to get at.

@Vesnog: It is not clear what your comment is contending. Are you trying to say you do not agree with or not understand my proof?

comment Proving susceptibility in Lorentz Model satisy Kramers-Kronig relations
I do not see why this is off topic. By the criteria listed in the help center on topics that can be asked, this question obviously falls in the category of "Mathematics in the context of physics" as the question asks about the specific relationship resulting from Lorentz model of electric susceptibility.

comment Total Momentum From a Standing Electromagnetic Wave
I am revisiting this post because of others, such as @lionelbrits, are. The assertion "no energy is being transferred to the matter of the cavity from inside so kinetic energy of the material cavity is constant in time. Therefore momentum of the material cavity is constant in time as well" is patently wrong. Consider a particle running with constant speed in a circle. Besides, I am asking for the spatial integral of the field momentum. This so called answer does not answer the question.

comment Total Momentum From a Standing Electromagnetic Wave
How is this kind of standing wave generated in an arbitrarily shaped cavity? I think one can only define standing wave as each component of a time Fourier transform of the field.

@Dronz: Thank you. I will check them out.

@Dronz: I know what you are saying. Even for spherical initial distribution, as assumed in your last sentence, with perhaps some perturbation, why should most the resulting semi-stable orbits lie on a single plane?

comment Why are our planets in the solar system all on the same disc/plane/layer?
@Dronz: "local concentrations"? If the elliptical regions that different orbits reside in are all disjoint and sufficiently far, there would be no collisions and no cancellations, and concentrations. You, just like the others, seem to put cart in front of the horse and cherry pick the reasons just to be able to draw the prescribed conclusion. That seems to fit more the characteristic of logical fallacy than scientific method.

comment Why are our planets in the solar system all on the same disc/plane/layer?
@Dronz: Yes, I have heard these before, and again this line of argument appears to form in hindsight: because in most of the examples we have observed --- I would not think the number is high as most planets and dust clouds in other solar systems are dark and thus unobservable --- the orbits are almost planar, so we fill whatever SEEMINGlY plausible reasons to convince ourselves this is almost always the case, whatever the mathematical rigor. It is a bit akin to the joke about psychologist's theory. Now to be more specific, why does "the large-scale distribution tend to have no major ...

comment Why are our planets in the solar system all on the same disc/plane/layer?
@Dronz: The concentration should be local. My question is why there can not be, with high probability, disjoint concentric elliptical annuli, at the distance of the solar planets in scale or larger for dust cloud, that are stable at the current solar system time scale, that planets or dust can rotate around the central star about very distinct axises.

@Dronz: "Stable" here is not required to be for time infinite and is defined relative to a given time interval. However, how does your comment relate to my question at all?
