dr dr dr! im cia he wasnt alone uh you dont get to bring friends theyre not my friends dont worry no charge for them and why would i want them they were trying to grab your prize they work for the mercenary the masketta man bane aye get them on board ill call ittin the flight plan i just filed with the agency lists smee maimen doctor pavelheer button lee juan ovyu first one to talk gets to stay on my aircraft who paid you to grab dr pavel he didnt fly so good who wants to try next tell me about bane why does he wear the mask a lotta loyalty for a hired gun or perhaps he's wondering why someone would shoot a man before throwing him out of a plane at least you can talk who are you it doesnt matter who we are what matters is our plan if i pull that off will you die it would be extremely painful youre a big guy for you was getting caught part of your plan of course dr pavel refused our offer in favor of yours we had to find out what he told you nothing i said nothing well congratulations you got yourself caught sir now whats the next step of your master plan crashing this plane with no survivors no they expect one of us in the wreckage brother have we started the fire yes the fire rises calm down doctor nows not the time for fear that comes later

comment Can the chance of finding a particle diminish over time?
@MarkMitchison: Right, do you know off hand if the complex energy models are placed, somehow, inside the theory which respects the "axioms of quantum mechanics" (especially unitary of time evolution), or are those cases considered a deviation of it (a tool to model certain effects without digging into a more detailed version of QM where unitary holds again.)

comment Can the chance of finding a particle diminish over time?
@MarkMitchison: That's the right answer. I've hesitated to make the same comment because OP actually mentions this in his first point. We can always go with "as far as we can tell, it just works", but I'd like to know if a theory, where at some time there is a chance of not being able to find the particle at, would have any use. I have no crucial argument against a theory which tells you "in 5 seconds, even if you look everywhere at once, the chance you find a particle at all is only 80%".

comment Moving electric charges
Note: I think the interesting question here is: In a fixed frame of reference, comparing zero vs. non-nonzero acceleration of an electrical charge, how does the change in time of the electrical field components in some distance of the ordiginal source differ? The answer must be found in the Maxwell equations, e.g. $\nabla \times \mathbf{B} = \mu_0\left(J + \varepsilon_0 \frac{\partial \mathbf{E}} {\partial t} \right)$. The question is why constant J gives a significantly different behaviour for the fields than a J which changes in time. Put differently: Why are field lines static for J const?

comment Wave/particle-duality as result of taking different limits of a QFT
@DanielSank: I don't know. Does this answer how I can take quantum electrodynamcis and in two different limits see classical fields resp. classical particles?

comment Wave/particle-duality as result of taking different limits of a QFT
@JohnRennie: k. As stated in the question, I'm interested in the explicit construction of the two different limits of one QFT claimed to exist in the article n page 4, i.e. this. Math is no barrier to me.

comment Does water maintain equal level in connected vessels?
I'm not in the position to answer the question, butI have no feeling for how big your construction is - the American units are somewhat alienating. I offer 250 Vietnamese dong to anyone who translates it.

comment Can interacting Hamiltonians always be written in second quantized form?
Why the downvote? Is my solution just too much outside the box or is it wrong? Going passed that, does the discrete sum remark not give a negative answer to the question?

comment Wave/particle-duality as result of taking different limits of a QFT
OP here. The paper suggestion you have two limits, a particle limit and another field limit. I'd like to know/see both different limits, and explicitly with some QFT.

comment Making precise the statement “particles are excitations in a quantum field”
Passing away from non-relativistic QM, as you say, to high energy physics isn't where things move from a single wave function $ψ(x⃗,t)$ to n-particle operator tools. You may always rewrite a term $∑_{i≠j}V(|r⃗_i−r⃗_j|)$ of a Hamiltonian describing an n-particle system as $∫∫∫d^3kd^3pd^3q\,V(q⃗ )\,c_{k⃗+q⃗}c_{p⃗−q⃗}c_{p⃗}c_{q⃗}$, where $V(q⃗)$ is the fourier transform of the potential. See e.g. the tight binding model in solid state physics.
