Sure but the normalization box follows the size of the photon wavelength. IOW, for a 1 millimeter wavelength photon, the "box" becomes 1mm^3. The quantum wave pattern and the classical wave pattern are basically the same with the quantum one being a probability for finding the photon.
Yes, but this for models with wave patterns being fundamental and from which photons are secondary effects. I understand that it may not be possible not to associate a volume in these models, but no such paremeter is needed in the 3 spaces model in relation with motion of particles in normal space. The underlying model is not wave based.

I personally do not assume any volume in normal space | for a travelling photon.

Yes, but do you assume that maybe part of the energy density *volume* is in the non-normal spaces?
Certainly. As I said in a prior post, the volume issue remains to be addressed in my model, because the energy is shared between the 3 spaces and is in constant cyclic motion between them. Besides, it is not needed to calculate velocities.
EMR does have a volume associated with its energy density. Does this volume disappear when we get down to the quanta of EMR? I am assuming that it doesn't. Even though it may be partially hidden from us in the "non-normal" space.
It certainly can't disappear from my viewpoint also. In my paper, it simply is not needed anyway for the paper's purpose, which is to explain the mathematical elaboration leading to equations allowing calculating relativistic velocities of an electron strictly from electromagnetic considerations, from my strictly EM-based model.

I don't follow the relation there. Maybe you need to explain more fully?
In reading the paper, care must be taken not to confuse "E" for "energy" and "E" for "electric field". The former is represented by a regular capital "E", while the former is represented by a bold capital "E".
Equation (11) gives the "energy" (in joules), and is equivalent to (h nu) or ((h c)/lambda).
In (41) and (41) you can see that energy equation (11) is a subset of these equations, so I substitute (11) in them so the "energy" value of the photon can be plugged directly into the field equations for convenience (if needed).
| > This is way off from what I have seen quoted in the literature. | | Of course, if you consider the concentrated density of energy within | a localized photon to be uniform all over the reference volume. But | this is not the intent of this equation.
I was assuming that the "intent" of eq. (34) and (40) were the "static" E_0 and B_0 field values for a photon. IOW, if you plug these into the wave equation, these are what would be the maximum measured values.
There is no way these values of E_0 and B_0 fields from my equations can be plugged into any wave equation. They belong to a different model, just like there is no way to plug Newtonian gravitional force into GR's inertial curved space model, or to plug a definite trajectory into the wave equation. Apples and oranges.

OK, this is where I am having some trouble with what you are saying. Your eq. (34) and (40) only have one variable, lambda, the wavelength of the photon. If you are specifying a certain volume for the energy density volume of a photon, then there should be another variable for that. Don't you think?
Possibly. Certainly in complete model description, but as I said, none is required for the purpose of this particular paper.
Even the statement you are making before eq.
(34) doesn't make sense from what you are telling me now. I think what
you are saying now, is that if you could measure the "static" B field of
a photon upon detection, eq. (34) is what would be measured. Is that
correct? Your statement is "Which gives us a generalized equation
capable of calculating the magnetic field of any isolated photon from
its absolute wavelength, all other parameters being constants."
I guess I should have inserted the word "local" before "magnetic field" in that sentence, but I thought this was obvious from the context. I mean local to the particle in motion (following it as it moves).
I guess what is bothering me here is "relative to what?". At the point that a photon would be found or detected?
None of the above. This is for photons in motion (as they are travelling at the speed of light, not as they are emitted or absorbed. The same for (49) and (58) regarding electrons in motion.
There simply can't be anything arbitrary about the values of a photon's
"static" E_0 and B_0 fields other than quantum uncertainty. In free
space there is only a photon's wavelength or frequency as the only
variable.
Yes. This is why the field can be determined either from the wavelength or the frequency, since both are dependant on one another for photons.
I have asked this question a few times and no one has ever been able to come up with another variable. So for sure the "static" E_0 and B_0 fields have to be directly proportional to wavelength.
Certainly.
| Think that both approaches are simply attempts at mathematical | "descriptions" of this or that aspect of what really occurs | physically at the fundamental level. None of them, nor any other | method could actually be the physical reality that we are trying | to describe.
Sure, but a mathematical description should be supported by experimental evidence.
My experimental evidence is the fact that equations (49) and (58) can calculate verifiable relativistic velocities of a moving electron from only EM considerations. Unless currently accepted theories can explain them otherwise, they are proof that the underlying new theory has some degree of validity.

If you could be in the frame of a photon, what do you suppose you would see? And how would you be able to measure any wavelength?
I guess that I could then measure its local frequency, from which its total complement of local energy could be calculated and then its local wavelength could be obtained.
A photon
only has a wavelength wrt emission or detection as far as I know.
In a model where there are no underlying fields, such as mine, the localized moving photon is the only possible carrier of its own energy, so it obviously carries this information as it moves all along the trajectory that it follows between emission and absorption.
What
might have been radio photons wrt the emission frame could be gamma
photons wrt the detection frame if the detector and/or the emittor are
moving rapidly towards each other.
Certainly. The relative velocities of emitter and detector could be factored in.
I think for this discussion we need to limit ourselves to photons that are emitted and detected in the same frame. IOW, the emitter and detector are at rest relative to each other.
That would be way simpler indeed, and it is actually the context of the paper also, for simplicity's sake.

Hmm... I think you lost me here. How do you get relativistic
velocities from (49) and (58)?
This is precisely what the paper explains, with all required mathematical sequences. For any deeper understanding, I guess that mastering the 3 spaces model would be required.
They are simply "static" B and E fields.
The E and B fields that I defined are for "moving particles", consequently, they follow the particles and can in no way be static.
| I think you assume that my E and B densities are 6 orders of magnitude | off probably because you assume these densities not to be localized | (which they are, and even reduce to point events in normal space in | my model), but to pervade whichever reference volume you care to | refer to, which is not the case. In whichever volume you associate, | your equation (not mine) gives the right value.
Well, when you say "localized", what does that mean exactly?
By localized, I mean that in my model, at any given moment of its motion, a photon can be in only one place as it progresses along its trajectory from emission to absorbtion, and that its local fields are permanently centered on that location.
As far as I can figure, a photon could only be "localized" to a volume no smaller than lambda^3/2pi if we cheat and could be in the frame of a photon.
Possibly, but as I said, I still cannot assess the variable volume aspect in my model. Besides, as already mentionned, it is not needed for the purpose of the paper (showing that relativistic velocities of the electron can be calculated from strictly EM considerations and providing the equations to do it).
For detection, it could only be "localized" on the order of a circular area with a radius of lambda/2pi. This is actually an experiment that I would like to see done some day.
That certainly would be interesting.
