Is Kinematics Compatible With Field Symmetries? by Stephen M Sycamore

Stephen wrote:

The value c is the only obvious velocity parameter embedded in the

Maxwell equations. It is derived from the combination of the vacuum permittivity

0 and vacuum permeability constants μ0, the former being effectively a conductance

facilitating parameter while the later is a resistance to the passage of energy through.....

Slightly different considerations apply to the so-called permittivity of free space, which historically has been regarded as a separate physical constant in some systems of measurement but not in others.

Dear Stephen,

You present an interesting, clearly written, and, I believe, timely paper. I believe that the whole issue of group symmetry in physics ought to be revisited very carefully and without prejudice. This is not to suggest that group symmetry is not an important concept in physics; to argue this would be rather absurd given the (partial) successes of relativity and the standard model. However, you point out one of several different very important instances in which group symmetry either does not completely account for the physical phenomena to which it is applied, or accounts for them in a less than natural manner.

Like you, I doubt the Lorentz group symmetry interpretation of covariance. Although my reasons and my approach are somewhat different, I admire the courage to question such a sacred pillar of modern physics. It is popular in modern physics to view group symmetry as the best (perhaps only!) way of expressing simplifying or unifying ideas, and this is very far from being true.

Thanks for the great read! Take care,

Don't forget please impartially evaluate my essay

Dear Tom Phipps,

May I ask you to check whether or not my essay derives a largely correct and possibly important suspicion from your papers?

Sincerely,

If you do not understand why your rating dropped down. As I found ratings in the contest are calculated in the next way. Suppose your rating is [math]R_1 [/math] and [math]N_1 [/math] was the quantity of people which gave you ratings. Then you have [math]S_1=R_1 N_1 [/math] of points. After it anyone give you [math]dS [/math] of points so you have [math]S_2=S_1+ dS [/math] of points and [math]N_2=N_1+1 [/math] is the common quantity of the people which gave you ratings. At the same time you will have [math]S_2=R_2 N_2 [/math] of points. From here, if you want to be R2 > R1 there must be: [math]S_2/ N_2>S_1/ N_1 [/math] or [math] (S_1+ dS) / (N_1+1) >S_1/ N_1 [/math] or [math] dS >S_1/ N_1 =R_1[/math] In other words if you want to increase rating of anyone you must give him more points [math]dS [/math] then the participant`s rating [math]R_1 [/math] was at the moment you rated him. From here it is seen that in the contest are special rules for ratings. And from here there are misunderstanding of some participants what is happened with their ratings. Moreover since community ratings are hided some participants do not sure how increase ratings of others and gives them maximum 10 points. But in the case the scale from 1 to 10 of points do not work, and some essays are overestimated and some essays are drop down. In my opinion it is a bad problem with this Contest rating process. I hope the FQXI community will change the rating process.

Thank you Steve.

I rated your essay maximum.

I'd like to re-state a couple of additional observations that follow from the essay here that were made in forums for other essays. This essay focuses on developing the mathematics at the fundamental level, i.e., the microscopic level of elementary particles. But as you step up a level or two to the macroscopic realm you may determine the permittivity and permeability on the basis of the volume density of each particle species. From there you can fairly easily determine the effective propagation speed of EM waves.

The dielectric tensors used to determine values in the constitutive relations are, in a rough sense, microscopic homomorphisms of the tensors used in Minkowski's electrodynamics for macroscopic calculations. Obviously getting things right in the microscopic domain has large advantages to only getting something that sort of works in the macroscopic domain. This may explain why space-time no longer appears uniform or continuous at the microscopic or quantum level.

Stephen

Brilliant enlightened view from a mathematician.

Dear Steve,

Do you support Peter Jackson's reaction to the file forerunner?

Eckard has called on your expertise. I agree you should be able to assist. I copy my most recent post here;

"Eckard

I responded to your post on my blog with more links (as you felt one was inadequate) and don't have Google. (I refer to your post about my wishful thinking and lack of knowledge).

You suggest my; "reasoning starts with the wrong for waves in the far field assumption that the wave speed re medium depends on the emitter."

The exact reverse is true. You had understood that a few weeks ago but seem now to have forgotten again. I can find no cause for this except that again you didn't follow my advice for gaining better comprehension. I've suggested we all need to dig deeper to find and remove those assumptions which we otherwise revert back to as a 'default mode' the moment we loose concentration.

In fact this is as true for sound, your familiar subject, as it is for light. The signal from the ear to the brain has a 'wavelength', which varies subject to the motion of the body. I suggest a calculation will show this also differs from the wavelength in the 'outside' medium. It would take a completely fresh view of the familiar to see the important consequences of this; The frequency is inversely proportional to lambda, as speed is controlled by the local medium. It is precisely the same for em waves.

I think my full reply on my string should straighten this out. You say you defer to Steve Sycamore's expert view. I also respect Steve's view and believe he'll unequivocally confirm the above. I'll flag this conversation up for Steve to comment."

Thanks, and Best wishes

Peter

Hello Mr Sycamore,

Sorry for my late answer, I forgot this thread. I have not published, I just share my Theory of Spherization since more than 8 years everywhere on net on several platforms.I beleive that it is an important discovery and that I must share it to the world simply.Of course I know the human nature but the most important for me is to share it in a total transparence. I have difficulties to resume. I am isolated at home. I like this platform but I beleive that several persons try to profit of my work. It is probably the reason why my pc is hacked. It is not important , it is the human nature.

But let's return at the topic of this thread. Firstly I must say that the name is stirling with a i :).You know, his work is very relevant considering the pure thermodynamics. The proportions appear easily with the rotating 3D spheres. The gravitation is quantized in fact......rotations are proportionals, the volumes are relevant considering the main central sphere. My equation mcosV=constant becomes an universal key for the thermondynamical correlations.The 3D is essential.

Regards

Steve

Re our exchange in Ben's blog.

While I would never understand some of the maths, I do not want to comment too much on the underlying logic (spacetime, c, etc) because I might just be pre-empting conclusions which I have in my head but want to confirm by finishing that paper (the first half of which was a response on Ben's blog).

Though the history is irrelevant, my simple understanding is that Voigt and Doppler were using the concept of local time. Understandably though, because they were trying to represent effects which occurred over time. Lorentz uses local time later, with Poincaré in the background with his misconception of time and timing. In very crude terms: it was rather like 'pin the tail on the donkey'. Through all the deliberations over ether, ether movement, light, light speed and direction, earth movement, etc, there was deemed to be variance, and time finally provided a suitable candidate. The problem is that this is just associated with observation. Hence the appearance of c in so many equations. Which raises the rather obvious question as to what has the speed of an effect in photons got to do with it?? It could be that a differential in gravitational force applied, ie a force, because only differences have the effect, could cause dimensional alteration, as well as momentum change. This was their original position, it was never rescinded, and could be correct.

SR is a red herring

γ is really a generic expression for the relationship between a rate of change as is with that rate as is when referred to another reference which is altering. Forget c. It could be any v. Again, c is just a reflection of the fact that the entire model of physical reality has been built with c as the determinant. Light just enables sight!!

Neither is physical reality only three dimensional spatially, this just represents the minimum number conceptually possible. From any given spatial position, the smallest elementary particle could move (ie alter spatial position) by next occupying any other adjacent spatial point, of which there will be a definite number determined by the size (spatial footprint) of that elementary particle. So, the number of possible physical dimensions is half that number of those possible directions, as the concept of dimension relates to a direction, either way.

Physical existence (as it can only be known to us) is an n spatially dimensional state of the substance which comprises it, which exists in one definitive physically existent state at a time. The rate of change, obviously, being determined by the fastest form of change in physical existence. That does not imply that everything has changed in that duration, but if something has, then there is a different physically existent state. This is the tick rate of physical existence.

The big question here is, what can we assume to be the relationship between a unit of spatial relationship and a unit of change.
