Peter,

I have to react to a reply by Lawrence Crowell. Therefore I will only briefly tell you nthat i do not understand your questio n concerning Fig. 5.

You wrote: "Figure 5 was ... in a medium not 'the vacuum'. I assert there is no distinction ... . But, more importantly, were observations also taken and analysed from the rest frame of the air?? or, to look at it another way. If the air were at rest and both emitter and 'mirror' moving in unison sideways."

Feist's car was moving with 120 km/h relative to the air being at rest re ground. The signal was emitted as well as received by the 220 kHz distance finder E which moved together with reflector R "in unison sidewards" because E and R were arranged on the roof of the car with the line ER perpendicular to the direction of motion. Measurement in a wind channel would also be possible but not so easily feasible.

You speculated: "With 'light' the findings would then be different (Kinetic Reverse Refraction)." Wouldn't refraction require different media?

Eckard

John,

I consider Tom's view in agreement with mainstream mistakes. He and all the others do not understand that even obviously matching denotations for elements of reality are subject to possible changes that may put the chosen identification in question. Roger Schlafly stated: "Nature has no faithful mathematical representation."

Presumably, not even Tom will deny that this is correct for the entity of all aspects. On the other hand, Tom argues that there is no reason to doubt that some well confirmed observations and laws of nature are true. He, Lawrence, and many others even refuse to question Einstein's special theory of relativity, and set theory (ST). ST was correctly still called a belief by Hilbert is now established as if it was a fact. Let me call the mainstream (which was called by Weyl the rats who followed the piper Hilbert like the children of Hameln) naive which means too ready to trust in something merely intuitively founded and now at odds with other intuitions. Some most questionable intuitions behind modern mathematics and physics are addressed in my essay. They are typical human fallacies, in particular driven by the desire for rigor and generalization.

Eckard

With the suggested Cauchy-modified Euclidean notion of number, sinc(x) has no singularity at all. Pebble mathematics declares sinc(0) a removable or cosmetic singularity. I see the latter denotation indicating a wrong notion of number.

I would like to clarify: Kept for appropriate descriptions of physical phenomena must not include any singularity. Of course, the electric or magnetic field of a point charge or line conductor have poles for r=0. However, these poles are artifacts of models that are invalid for r=0.

I anticipate disbelief and hope for objections from theoreticians. Please tell me an example of an experimentally confirmed physical correlate to a mathematical singularity.

Eckard

The issue with negative frequency is not hard to understand. First off if I were to build a band-pass filter if this were to select for negative frequencies it would mean I need an inductor with a negative inductance. This frankly does not make sense. How one construct a device to measure or that would admit a negative frequency? Of course one can construct any type of mathematics with a negative frequency, but that is not the same as physics.

It is the case of quantum mechanics a negative frequency does correspond to negative energy. The energy of a photon E = ħω has sign dependency with the angular frequency ω = 2πν. Suppose we have a particle with mass 0 > m. Suppose this particle decays into photons, then the photons clearly have negative frequency

mc^2 --- > 2ħω,

and of course if we have negative frequency photons we can have the converse process. As a result we may generate a negative mass particle.

Negative mass particles are quirky. For one thing Newton's law of gravity F = ma = GMm/r^2 indicates that if we have M positive and M negative with

Ma = -GMm/r^2

ma = GMm/r^2

that the two masses are accelerated in the same direction. In fact if the two mass have the same magnitude the two race off indefinitely to "infinity."

This is related to the issue of tachyons. What is the problem with tachyons? The relativistic momentum-energy interval is

m^2 = E^2 - p^2

where I have set c = 1. The magnitude of the momentum is greater than the energy and so m^2 is less than zero. The energy E = sqrt{p^2 m^2}defines the velocity

v = ∂E/∂p = p/E

which since p > E is greater than unity. This has the meaning that the particle moves faster than light. The interval defines the Klein-Gordon equation ∂_t^2 - ∂_i^2 = □ so that □ψ = m^2ψ. The term m^2ψ comes from the potential V(ψ) = (1/2)m^2ψ^2, and the gradient of the potential ∂V(ψ)/∂ψ = m^2ψ is less than zero. Hence the vacuum state is not stable.

The relationship between the negative mass particle and the tachyon is seen if we consider the extreme boosted situation with p^2 = p_x^2 p_y^2 p_z^2 and p_z much larger than the other components. We may then write the energy as

E =sqrt{p_x^2 p_y^2 p_z^2 m^2 }

~= p_z sqrt(1 (p_x^2 p_y^2)/p_z^2 m^2/p_z^2}

and binomial theorem gives

E =~ p_z (p_x^2 p_y^2)/2p_z m^2/2p_z)

And p_z plays the role of a Lorentz factor. This is a very classical appearing equation and the last term is interpreted as a mass μ = m^2/p_z that is negative. So the negative mass physics is related to the tachyon physics in this extreme boosted situation.

So there are a number of strikes against this idea of negative mass and negative frequency. Ashoke Sen has found that tachyons can form condensates in D-brane physics. These are special cases, such as the M2-brane in a black hole interior, where the tachyons are not free to propagate.

Cheers LC

    Lawrence,

    Negative mass particles are not quirky. They are the result of neglecting pre-mathematical issues. Strikes against the idea of negative frequency are only reasonable if this idea claims to attribute the negative frequency to physical reality. My essay tried to explain this as understandable as possible to all those who are ready to read it step by step. Negative frequencies are a must with complex function of elapsed time. They vanish with correct inverse transformation back into reality.

    The most compelling reason to doubt the existence of absolutely negative mass, energy, pressure, temperature, tachyons, etc. is not that they were not experimentally confirmed. They will certainly never be found in reality if they are just artifacts of faulty pre-mathematics. I see no justification for the intuition that every mathematical object has a correlate in physical reality. On the contrary, It reminds me of the likewise naïve idea that thunder must be made by Thor who was imagined like a man.

    You may believe in tachyons. I see them more fiction than science and perhaps meaningless. Do you see any possibility to refute my perhaps more important hint that the mirror symmetry of past and future time, which puzzled Hermann Weyl, can easily be explained as the failure to be aware of a tacit transformation with a complex "ansatz" and perform the due inverse transform after calculating in complex plane based on assumed physically correct only positive frequency. While I am also among those who are too lazy to each time perform all steps of transformation and return, I tend to know what I do and how to immediately interpret results I got in complex domain.

    Hello Eckard, thanks for your comments on my essay, and sorry I took some time to comment on yours, am on holiday and on the road with my partner at present. I found some of your essay interesting - one thing, you say that Einstein's:

    "...obviously unrealistic denial of past and future in theory is a consequence of a very old fallacy which is hidden within the assumption that our commonly agreed event-related time scale is a basic physical quantity."

    The reason he thought there was no distinction between past and future is that Minkowskian geometry leads to that conclusion, and we often believe our old school teachers. But people are beginning to question Minkowski's work, as I have done in my essay. There have even been some rather desperate attempts to get rid of the lack of distinction between past and future, while keeping spacetime intact. I've argued that these don't work, because in spacetime, the distinction between past and future is purely observer-related, and depends on relative motion only. So it can't be about the collapse of the wave function, or other things that people ascribe it to, if spacetime is right. I've argued that there must be an error in the spacetime geometry, and that we have to look deeper to remove the problem.

    I disagree that time strictly cannot be measured at all - a time rate can be measured in relation to another time rate. We don't know what causes these relative time rates, but they can be measured in relation to each other.

    Anyway, best wishes, Jonathan

      Dear Eckard Blumschein,

      In a comment to John, you appeared to disagree with several essayists who "seem to intuitively believe in the correctness of the very foundational assumption that reality has been built on mathematics."

      For this reason I'd like to make you aware of a comment that I posted [to all FQXi'ers] on this topic:

      "This essay contest presents a number of contradictions, yet it is enlightening and eye-opening. My thoughts at this stage, after reading most (but not all) of the essays is stated in a comment I posted on Edward J. Gillis' excellent essay. The gist is as follows:

      Despite the assumption that Bell's inequality is valid, an assumption I reject, I agree with you that "in order to make current theory logically coherent, we need ... indeterminism...".

      You say our brains, "figuring out what we can control" bias intuition in favor of determinism. Yes, but free will does not fit a deterministic view and my intuition is comfortable with it.

      As I recall Bernard d'Espagnat noted that our world is based on three assumptions: realism, inductive reasoning, and locality (linked to speed of light). Believers in Bell tend to retain logical inference at the expense of local realism. Perhaps this should be reconsidered.

      Several essays in this contest suggest that space-time, locality, unitarity, and causality are "emergent", that is, not fundamental, but artefactual, emerging from deeper fundamentals, akin to temperature emerging from statistical ensembles of particles. Yet they apparently assume that logic and math survive even when space-time, locality, and causality have vanished (coming 'as close to "nothing" as possible').

      I have presented logic and math as emergent from real structure (in 'The Automatic Theory of Physics') and if I am correct, then one cannot assume that one can banish space-time, locality, and causality and yet retain logic and math. [To do so one must be a 'Platonist', having a religious belief in some realm of 'math' not unlike religious belief in a 'Heavenly realm'.]

      My intuition and my experience tell me that reality is both 'real' and 'local' while they also inform me that logical coherency is *not* universal. For instance this FQXi contest contains a number of 'logical maps' that span various regions of the 'territory' [physics], but they are logically inconsistent with each other [and potentially contain logical inconsistencies within themselves.] If anything, this problem grows worse daily, as new math and new physics ideas branch in new directions. Despite the claims of various schools of physics, there is no coherent 'Theory of Everything', nor does one seem to be in sight. Many deny even the possibility of such. Given this state of affairs, I am ever more inclined to believe that the Bell'ists have made the wrong bet, trading local realism for logic, and losing on both counts.

      Perhaps a new understanding that 'logic is local' needs to replace the [probably faulty] assumption that 'logic is universal'. My essay is one approach that assumes local realism is fundamental."

      As I hope to aggregate arguments on this topic, I invite your response on my thread.

      Edwin Eugene Klingman

        Hello Jonathan,

        Lawrence just illustrated implications of the question you raised. Although Minkowski was a teacher of Einstein, he credited Einstein for the basis of his spacetime. I read this in German. There is definitely a good translation into English. I do not even blame the idea of spacetime for useless. Maybe, the divine bird's view on past and future is about as clever as the obviously only approximative linearizing of pressure in acoustics.

        I tend to rather blame the not very well educated Dirichlet, G. Cantor and Einstein for bringing naive intuition into science. Minkowski called Einstein a lazy dog who often skipped his lessons on mathematics. I see a clever logical split in Einstein's thinking; he merged the divine perspective looking over all past and future with the perspective of a real observer.

        Einstein made a related mistake when he used Poincaré synchronization. This view effectively binds the distinction between past and future to the observer instead to the object it relates to. I hoped Georgina did find out this flaw more clearly.

        In all, we may resort in case of Einstein too to the Lessing quote Ebbinghaus made in his textbook "numbers" when he dared to admit indirectly that G. Cantor was horribly wrong:

        If someone by an obvious mistake came to a valuable truth ...

        Best wishes,

        Eckard

        Eckard

        You'd need to understand 'Kinetic Reverse Refraction' (KRR) to understand my question. KRR is well known in optics but not well enough known outside as not rationalised into present theory. All good optics text books cover it, or this is one good link; 'Refraction between moving media'. http://mathpages.com/rr/s2-08/2-08.htm

        Essentially, to an observer at rest in the air, the emission axis rotates in the OPPOSITE direction to that 'observed' from the 'car' frame.

        You already agree remember that there IS a change in 'medium' (ambulance siren) from the emitter to the air; consider a siren inside the cabin as a headlight bulb, and the windscreen as the lens, the sound and light change propagation frame (co-moving medium) just AFTER emission. Observers inside the cabin, or the light lens, see the light first emitted in the emitter frame NOT the frame of the outside air. Ergo refraction has to occur before any Doppler shift of wavelength (thus derivative f) can be found by any other observer (where the process repeats in reverse). But do read the link, because it's easy to forget again when applying it due to unfamiliarity.

        If you then look at my own figure 5 you can see the mechanism which explains both KRR and the findings of your own figure 5.

        In a vacuum this becomes the 'Light Box' paradox. A light pulse bounces up and down, but when in relative motion to an observer it would appear to have an angled path so be superluminal. Tat's why Einstein needed Length Contraction. He said the box must then contract to conserve c.

        So why would the light pulse not stay bouncing up and down when the box and it's mirrors moved off sideways!!??

        KRR and my Fig 5 explain this without contraction of the box, and if the sides of the box were removed then the pulse WOULD stay vertical when the box moved away. Therefore intuition and logic is reclaimed. (as well as Snel's Law in KRR.

        That is why Feist's findings are no surprise at all once the real process is understood. Only retained assumptions about how things work prevent this understanding.

        Peter,

        Thank you for guiding me to "At the end of my Latin". I agree on that "Feist's findings are no surprise at all once the real process is understood". Be sure, I carefully selected and designed each of my five figures with the intention to enforce an important reconsideration.

        Admittedly, I failed to understand on the first glance what message you intended to offer with your figures. You mentioned your Fig. 5; I only found four of your figures.

        What about kinetic reverse refraction KRR, "a phenomena not yet assimilated into

        physical theory" you did not yet explain to me how it may relate to my Fig. 5 where the wave propagates in only one medium with always the same refractory index. All explanations of KRR I found refer to refraction at a boundary between two media with different indexes.

        I agree with Don Johnson's arguments in Galilean Electrodynamics 2006, 3-7 against Wheelers SR related illustration of transverse motion.

        I will read Shtyrkov's 2011 paper in Russian on the Michelson experiment and have a look at Dowdye's 2006 Introduction in the Extinction Shift Principle you made me aware of. While my Fig. 5 shows reemission, I do not see this a justification for the implications ascribed to emission theories so far.

        Eckard

        Dear Edwin Klingman,

        Just a few spontaneous lines. I will follow your invitation later.

        As I wrote in 3rd contest, the claimed freedom of mathematics contradicts to the belief that "reality has been built on mathematics".

        In my 4th essay I revealed my view that Hilbert prematurely subordinated meta-mathematics and logics to mathematics, and that I am admitting reality ultimately as a fictitious intangible model of what agrees without exception with observations, experiences and predictions in contrast to illusions, speculations, and mysticism. Any organism without such model is doomed to die.

        I do not see any reason why this model should obey merely intuitive conclusions or take theories for finally confirmed. For instance, Ohm was wrong when he concluded that a missing fundamental cannot be heard.

        Do foundational question reasonably include doubts in reality? Well, several essays demonstrate readiness to even question such notions like causality and locality in order to save theories that were accepted. I see it already an attack on common sense if causality and limited speed of light are put on the same level with spacetime and unitarity.

        While I do not know any evidence against causality, I see complete determinism a naive intuition and at variance with the possibility of a potentially infinite world. To me, free will is just a metaphor for a not yet decided future.

        Engineers like me tend to put the 'as close to "nothing" as possible' into the drawer of signal to noise ratio.

        While reality is necessarily 'real', I do not share your pessimistic guess that logical coherency is *not* universal. Maybe, it cannot be easily enforced. We all will hopefully contribute to the removal of unnecessary obstacles.

        Best tegards,

        Eckard

        Dear Eckard,

        I always enjoy your replies, and particularly your mastery of mathematical history, which you use to illuminate many areas.

        I agree that "complete determinism [is] a naive intuition and at variance with the possibility of a potentially infinite world."

        As for "While reality is necessarily 'real', I do not share your pessimistic guess that logical coherency is *not* universal. Maybe, it cannot be easily enforced" I see the 'logical ideas' we have as due to essentially separate logical structures that exist in our brains, some learned from playing baseball as children, some learned from sitting in calculus class, and these structures are not wholly integrated and fully unified, nor are they universally correct and compatible. The question is then whether these separate maps, or combinations thereof, can 'cover' reality coherently. Maybe, maybe not.

        Of course this depends upon the correctness of my view that logic is structural in nature as opposed to mystical in nature, and also to the degree that structures (neural nets) that are connected uniquely in each of us can 'rise above' this dependence on individual experiences to be isomorphic with those of others. It's amazing that a few simple theories like Newtonian mechanics, special relativity, and quantum mechanics can bridge these differences in most physicists minds, but to expect it to do so for the "potentially infinite world" you mentioned seems to me to expect a lot. And this does not even take into account the dimensions of reality of which Kyle Miller speaks.

        Thanks for sharing your insights,

          It easy.You can read my essay.

          You are right.My russian English not so good,but text is quite clear.

          Dear Eugene,

          Isn't physical reality something objective that does not depend on the perspective of an observer?

          What about logical structures in the brain, they are known to be flexible.

          LSD in the title of Kyle Miller's essay deterred me, you made me curious. I found not much to agree on and nothing new in it.

          Best regards,

          Eckard

          Hi Eckard,

          Yes, I believe that physical reality does not depend upon the perspective of an observer, but 'physics', the map of reality, generally does to a large extent.

          And in quantum theory this includes "counterfactuals" and perhaps other concepts that may affect theory.

          Although logical structures in the brain are quite flexible, I do not believe that the structures that we use to map the world are 100 percent integrated or otherwise seamlessly overlapping. Certainly these maps differ from brain to brain, and I believe they are similarly dis-integrated in one brain. And I am not sure whether or not there are logical issues having to do with the way our brains process self-referential logic.

          The point is that physics (per d'Espagnat) is based on realism, logic, and locality, and most Bell theorists have decided to forego realism and locality in favor of retaining logic. But to me, logic is the most mysterious and least understood aspect of the three, while both my theoretical model and my mind tell me that local realism is valid. I cannot prove that the problem lies with logic, but I do not consider that anyone has proved that local realism is false. If I'm forced to choose, based on incomplete knowledge, I choose local realism and fuzzy logic (not "the" fuzzy logic).

          As for Kyle's topic, I had missed it until I saw Georgina's comments. The topic is not an easy one to discuss. I have written in past contests about the effects on perception which I interpret as 'suppressing' metric awareness of distance and difference in favor of topological awareness of connectedness and unity. It is, in general, not a topic that goes anywhere as most who have not experienced it have no idea what is being discussed, while most who have experience of it have not the physical or metaphysical concepts to make sense of the experience.

          I hope this response addresses your comment.

          Best,

          Edwin Eugene Klingman

          Please try to object:

          Poincaré's method of synchronization assumes that a signal needs the same time from an emitter A to a reflector B as return from B to A. It is obviously correct as long as the distance between A and B remains unchanged. The synchronization suggested by Einstein in 1905 extends Poincaré's method on the case that A and B are linearly moving relative to each other with constant speed. Einstein was not yet wrong when he argued that that synchronization requires measuring. However, he ignored that the simultaneity cannot at all be achieved by a single round-trip measurement ABA. Instead one needs for instance simultaneous measurements AC and BC with reference to a neutral point C. Having defined an A-time and a B-time, Einstein tacitly assumed A at rest ("Zeit des ruhenden Systems") but B the moving system. Thomas van Flandern aptly criticized Einstein's synchronization as desynchronization.

          Einstein wrote: "Hence we must not attribute absolute meaning to the notion simultaneity. Two events that are simultaneous if looked at from one coordinate system must not be considered simultaneous events if seen from a system in motion relative to it."

          Of course, an observer cannot judge the temporal order of two observed events without further knowledge. Einstein's special theory of relativity has been based on the confusion between reality and what an observer measures.

          Eckard

          Eckard

          You again assume without thought that the detector itself, (ignoring the reflector) is not involved in the process. ("...the wave propagates in only one medium...")

          This is the wrong assumption I'm discussing. In fact the Hutchinson essay also explains the relationship if not the massive implications quite well in another way, showing the detector cannot detect anything without the light negotiating a a refractive plane (i.e. frame change);

          "...In every free space solution for a detector, either the detector has detected the quantum or it has not. After diffraction, the solution almost certainly converges to just one such set of overlapping free space solution because any other solution would be unstable."

          This is indeed the precise situation for the KRR experiments. The detector (lens) is in lateral motion wrt the incident medium. So the KRR effect does apply, and all anomalies are resolved, and Snel's law is recovered.

          It seems you perhaps tried to read the essay too fast and lost track of the complex logical consistency.

          Peter
