Dear doug,

You wrote: "the idea of rational numbers embedded in a continuum is ludicrous." I would not say ludicrous because I see it rather a clever kind of self-deception. It works well in nearly all situations because approximations by rational numbers can be as accurate as desired. However, I gave exceptions in my Appendix A, in my references Aseltine and Terhardt, and in previous essays and discussions.

You also wrote: "called irrational for a good reason". Yes, they cannot be written as p/q with p, q finite. The other meaning irrational does not apply because mathematics is not beyond rational thinking.

Dear Steve,

You might easily find yourself how the zeta function and pi are related.

You will however not find anybody who frankly admits as do I that so called rigorous mathematical (Dedekind 1888, Peano 5th axiom) induction is utterly useful for arithmetics but strictly speaking not correctly applicable to real numbers that are really different from the rational ones.

Conclusion from n to n+1 works for any n but definitely not necessarily to the entity of all. This is my old fashioned notion of infinity. It seems to be trustworthy. From this side I have no reason to suffer from mental illness or commit suicide as did G. Cantor, Boltzmann, Hausdorff, Turing, and Grotendieck.

I am confident that sooner or later mathematicians will find the way back to pre-Dedekind basics.

What about my insight quantum theory could - contrary to Pauli's opinion - in principle be described without complex numbers, I see this already supported by Freeman Dyson, John Baez, and here by Andrej Akhmeteli.

So far I did not yet get support for R+ as the tailor-made domain. This is understandable because we all were indoctrinated to integrate from minus infinity to plus infinity while physics cannot deal with something it does not anticipate. In other words, consideration is at least restricted to one side while of course there is no known limit for the past as well as for the future.

However, future is more or less uncertain.

Dear Peter,

I see two easy explanations for measured superluminal velocity: a mistake or an illusion. Admittedly I did not yet deal with your explanation how the latter might work as an apparent velocity. I admire your ability to read so many news. Decades ago I decided not to watch TV any more because to much information is difficult to digest at least to me.

I still did not yet understand what you meant with " 'Lorentz' (actually originally Fresnel) exponential curve". The Lorentz factor as a function of velocity is no exponential function.

I also did not yet understand why you seem to prefer a "digital" field theory.

Eckard

Eckard.

It is simply exposed by analogy.

A boat has a maximum speed of 'c' kph. It is moving on a river, which is flowing at v kph. 20 observers (Ob1-20) are given video cameras and told to record it so it's speed can be analysed. The first 17 take the video from cars going up and down the bank, and back and forth over bridges, from trains, cycles, aeroplanes, the space station, the moon, jogging across adjacent fields and from other moving boats. They all get different results!! Ob18 is standing still, on Earth, on the river bank. So.. Does he get the result 'c'?

Of course not he get's c plus v.! ...Ob19 then uses the Hubble space telescope camera! SO... Does he get 'c'? ...Of course not - he gets c plus v plus v2(=orbital v of Hubble).

So.. one left! Ob20 is the only intelligent life form. He jumps into the water, or onto another boat, and float at rest wrt the water, videoing the boat as it comes past close by (LOCALLY), and his result gives precisely 'C'.

The stream from the Quasar is the river. it has 'incentric' (graded) motion, going slow beside the bank and fast at it's centre. (There are some super cross sections through the jet streams from spectroscopy in some papers on the web). In all this time the boat was complying with 'c' and knew nothing of all the fools rushing around with cameras, who might as well have been on another planet!

Was that understandable?

The sq root formulae was originally Fresnels, for another (proper) purpose. The term was wrong, is there a handy term for the infinite curve produced?

I DON'T actually prefer a 'digital' field theory. Nature may be called whatever we wish but the model consists of an unknown condensate field of energy potential which is of limited compressibility, equivalent to Edwins 'C' field or the old 'ether', so may be as continuous as the waves it propagates. When perturbated or compressed (by meeting a medium doing 'a' relative speed) particles are condensed. These are initially ions, i.e. a plasma. These then impliment the change in f and or lambda (subject to which way the observer is rushing around with his camera!) to maintain 'c' and conserve E locally within the new co-moving medium. These ions can bunch together to make more or less intelligent life forms and their houses.

i.e. Matter would not exist without discrete particles, but the field they condense from is continuous. It is not however entirely a continuum! as it is in what might trendily be termed 'blocks' of continuum. Whether we call a wave continuous is semantics! (see Ken Whartons excellent and very readable essay).

If you'd like any of the evidence follow the references or do just ask.

This is mega paradigm changing stuff you know!

Best wishes

Peter

Dear Steve,

You asked: "who was the best rationalist, the most rational and logic between these persons,

Dedekind, Cantor,Riemann,Gauss,Poincarré,Pierce,Euler,Stern,Dirichlet,Hilbert

."

Among my favorites are Euclid, Galilei, Euler, and many others also including Peirce. The latter stands for what the other you mentioned made or considered outdated.

When I wrote pre-Dedekind mathematics, this was a questionable simplification. While I found the old and physically correct Euclidean notion of number still maintained up to the time of Dedekind, its mathematical mutilation to just a single point begun earlier. Let me consider the row Gauss, Riemann, Stern, Dirichlet, Dedekind, Cantor, Poincaré, Hilbert.

The book by Nahin to which Edwin Klingman pointed me made me aware of even elder roots. My admiration for Gauss has become overshadowed when I got aware of his arrogance. More factually, I dislike that he promoted the complex plane, which goes back to Wallis, Wesse, Argand, and Hamilton, without to stress that it is not accessible via Euler's identity but via an omission.

I see Riemann, Cauchy and others preferring to create pure mathematics that neglects the link with its application in physics. What about Moritz Stern, I did not find him mentioned in literature that describes the origin of set theory. While Dirichlet was lacking a solid education, he was nonetheless very influential in particular on Dedekind. Dedekind on his part managed to cautiously and elegantly advertise what I consider a clever seemingly rigorous self-deception. Frankly admitted having no evidence he kindly asked to nonetheless believe him. While G. Cantor had the same intention, he managed to provide stunning evidences and get a nimbus of a genius. Poincaré is told having called Cantor a charlatan. Maybe, he was not quite wrong in that. I like Hilbert's transformation. Hilbert was very disappointed when his successor Hermann Weyl rejected large parts of set theory. In all I see Hilbert's influence on physics with very mixed feelings. It was Hilbert who denied for mathematical reason that past and future are fundamentally different from each other.

Regards,

Eckard

Thank you very much dear Eckard for this beautiful aswer and explaination.Me My Favorites are Borh, Newton , Gallilei and Euler.

I agree about the works of Pierce, it's very inetersting and relevant, as what the rational logic will be always the best road.

The interpretations of the physicality can be made by maths if and only if the real domains are inserted with their pure finite series.

In all case, you are a real searcher of truths and truth.Thanks for that and for your knowledges.

O posted a reply on my page but it didn't seem to go through so I will post it here.

Yes I read your essay but I confess I did not give it proper thought the first time. I apologize to you for my posting as it was not well taken and you are absolutely correct in being disturbed.Your essay is very good and your points well taken.I shall endeavor to read further essays more carefully.

    Dear Eckard

    I am sure which might be the better place to submit a post so I am submitting to both our sites.

    Thank you for alerting me as to the rating system of which I was unaware. I will certainly now reread your essay (I have been fighting some deadlines here so I could not give this entire project the attention I would like. I am now going to take the time to read some of the other essays as the interplay between those of us who entered essays seems to be the most interesting part of this whole experience.

    Dear Tom Wagner,

    Having read several essays, I realized that almost nobody besides me addressed not merely continuous vs. discrete but literally analog vs. digital models.

    Accordingly most readers of my essay did perhaps not understand why I consider already DEQs the first step into ambiguity and complex representation twice redundant. The reasons for me to thoroughly deal with history of mathematics were mainly paradoxes not just in physics but also already in mathematics.

    I pondered about the possibility to restrict the scope of my essay as not to lose all readers. However, even if I was not in position to explain in detail how the many uncommon alternatives to established tenets are interrelated, this mutual dependency is important.

    What about the chance of getting these alternatives taken seriously, I so far hoped in vain for arguments that challenge me, and I can imagine how FQXi cautiously anticipates reactions of those who are definitely unhappy with what they will feel wrong and an attack on their theories. Not all posts are immediately shown. My votes did not change the indicated rates and numbers of public votes. Nonetheless I highly appreciate the opportunity to take part in a polite factual discussion without taboos.

    On the other hand, I consider most of the alternatives well founded, and I expect the outcome of LHC providing further support for my criticism. In the meantime, I can only collect further indications.

    Dear Eckard

    I have reread your essay and I do have a better picture of what you are saying. While I do have a fair layman's grasp of the study sub-atomic particles I do not possess the sophistication nor the experience in such matters to allow me to engage in a meaningful debate. I plan to read it again as there is much included that stimulates ideas.

    I was struck by your reference to Sommerfeld on page four. When he states that no wave is reflected from infinity in finite time sounds a bit like the notion that a moving object cannot transverse an infinite number of points in a finite amount of time. Be that as it may, I am more interest in the next statement, Standing waves are strictly speaking approximations.

    A standing wave is a very definable and precise physical phenomenon. It is the initiator of most and perhaps all sound. This can best be seen in a musical example. More than half a century ago, Frederick Saunders wrote an article about the physics of music for Scientific American. This article had more errors and misconceptions that I have ever seen in one article. Saunders was a noted figure in the acoustical world, but physicists are only human (at least most of them are).

    One false assumption that most people make about the generation of a music as sound, and I use Saunder's example of an instrument such as a clarinet or an oboe, is that it is the movement of the traveling longitudinal wave that transverses the from the mouthpiece to either the end of the instrument or to the first open key actually creates the sound.. A conjugate is returned and wave moves back and forth through the instrument.

    Saunders makes the statement that it is the air that flows in and out of the finger holes that creates the sound. He then went on to state the fundamental is the only note whose sound goes out of the end of the instrument. If this were to be true then why do they put bells on both clarinets and oboes if they only affect a single note?

    The movement of the traveling wave back and forth sets up the frequency of the tone. The structure of the sound begins in the reed of either instrument. This is fed from the mouthpiece to the sides of the instrument. The movement of the air creates a classic standing wave, which is modified by the information residing on the sides. The severe impedance mismatch between the air and the materials from which an instrument is created means that the body of any instrument contributes little to the sound we hear. The primary interface that creates the sound lies across the plane of the open end of the instrument. This is why a bell increases the volume of the sound; it increases the area of interface.

    This is true of most instruments. The standing wave that forms in the body of most instruments is a resonance. Perhaps the biggest obstacle in understanding sound is the lack of understanding that a vibration and a resonance are two related but decidedly different things. Any material with some elastic properties will resonate to any frequency. Only if the resonance is near to the overtone structure of the resonating material will that material vibrate. On the other hand, a vibration is necessary to create the resonance initially. Both the vibration and the resonance are digital.

    Sound is not a single isolated occurrence; it is a process that ends in the Organ of Corti. The Organ of Corti is a fluid filled canal in the cochlea, which houses the hair cells that stimulate the nerves to the brain. The final argument for hearing being a discrete process is that the messages the nerves send to the brain are in the form of discrete pulses. They respond to an increase in amplitude by sending more pulses per unit time.

    Since all of the nerves that send data to the brain are quite the same we have to wonder if all sensations are transmitted to brain as discrete pulses. While I agree that the brain is not necessarily just a big computer we have to be aware of the fact that the complex of nerves that address the brain do behave a bit like a computer bus and the pulses are, in effect, bit patterns.

    Thanks for a very provocative essay.

      Dear Tom Wagner,

      Please do not take it amiss that I added Wagner. Tom alone is perhaps a too frequent name. You need not telling me acoustics. While my dissertation, forty years ago, was a comparative study of power electronics for arc welding, the superiority of welding by ear challenged me. Maybe you know the English professor and self declared pop star Chris Plack. It was he who told me that there is a Steven Greenberg of ICSI Berkely who uttered similar ideas on the mechanism of hearing as I suggested. The latter argued correctly that a frequency analysis alone could not explain the astonishing performance of hearing. For instance, onset is utterly important. Steven Greenberg organized together with Malcolm Slaney of Stanford an Advanced Study Institute on Computational Hearing in 1998 in Il Ciocco, Tuscany, and invited me to take part. Here I met virtually all important experts on hearing. Since then I thoroughly dealt with auditory function.

      Certainly you know the huge list that was initiated by Al Bregman and is maintained by Dan Ellis. Al Bergman asked for altruists as to get his list rid of too controversial discussions. Jont Allen and I each provided a forum.

      I intended to find out how the extraction of temporal features from sound might work and how to explain why the spectrogram has so many shortcomings. In the end I got increasingly aware of a cardinal mistake in theory of signal processing:

      Complex analysis and inclusion of void future data is a detour.

      Meanwhile I also got familiar with many details of the physiology of the auditory pathway up to A1. In Magdeburg we have a Leibniz Institute of Neurobiology. Moreover I regularly attended the annual meetings of DAGA (German Acoustics Society) and read JASA as well as ARLO papers. Currently I am just participating in a list on Cochlear Amplifier by Matt Flax.

      What about my statement that standing waves are strictly speaking an approximation, I should add that I was teaching fundamentals of electrical engineering for decades. So you may consider me a professional in this field.

      You wrote: "A standing wave is a very definable and precise physical phenomenon." What I meant refers to the fact that every signal in reality has a beginning and an end. We may describe it as a superposition of a transient and a stationary component. Neglect of the former is an approximation.

      If I did not sufficiently answer your question, please do not hesitate asking again. Questions by laymen are often valuable. We need not be able to follow for instance Lawrence Crowell as to find out why the theory of "relativity" and non-relativistic quantum mechanics do not fit together, why quantum computing does not work, and why so far neither the Higgs boson nor SUSY were experimentally confirmed.

      Dear Eckard,

      I wish I had a greater knowledge of the things you discuss in your essay. I think you are doing an important job of looking at the mathematics that is used to describe reality and what it really means to be continuous or discreet , analogue or digital. For models to be -realistic- these considerations need to be made. It is a very different approach to the other essays I have read here and a valuable direction of investigation. Because of my non mathematical background it is an essay that I will have to reread a number of times and digest slowly.

      I will admit that the thought "what do we -really- mean by continuous or discreet, analogue or digital?" did pop into my mind but having a huge body of content discussing reality there we was not room to also thoroughly consider that in my essay. I think you are doing that. I touched on it with the film photography. Which may be talked about as an analogue process but the film does have a chemical structure and therefore it is individual grains that change color or not.

      I did notice that Eugene Klingman in this thread mentioned the usefulness of having i orthogonal to a surface. IMO There is unseen spatial change over time, which is not visible from the perspective of the observer, at the same scale as the observed object. The direction of that change can not be a direction that exists within the 3 dimensional spatial structure of the observer's individual reference frame. It is an other direction. So therefore it can not be represented as a real direction or measurement because it is not seen and so is not measurable like a "real" distance.

      Your support has not gone unnoticed and is very much appreciated.I do hope your ideas get the attention consideration they deserve.

      Georgina.

        Dear Eckard,

        I enjoyed your essay which built a solid case for the superiority of digital signal processing and discrete representations. I thought that the historical references to Euclid, Leibniz, Gauss, Cantor and others were fascinating.

        Best regards,

        Paul

          Dear Eckard

          I was hoping to see a response to my post above. The more rigorous logical analysis is in a post I've just made to Tom in support of Georgina in the blogs (Time travel) but repeated in my string. I hope you'll look, as it identified conceptually and logically where our understanding and application of maths and SR was incorrect.

          I note I haven't scored yours yet and will do so now with the far higher one it deserves, as time is running out. I do hope you will agree mine deserves the same, if you haven't done so yet.

          Very best wishes.

            Dear Paul,

            In my understanding, foundational questions should not just include FOM (fundamentals of mathematics) but demand some clarification in FOM even if corrections might be painful to those mathematicians to whom aleph is a gospel and set theory the alpha and omega alias infinity of mathematics. I agree not just with David Joice in that the good old Euclidean notion number was abandoned in the 19th century. So far I seem to be the first one who makes this an issue. Cantor's "counterintuitive" infinities beyond infinity provoked distrust, and they got even used as to enforce purely formal thinking. I do not intend being considered one more crank who tries to disprove Cantor or Einstein. Having dealt with the foundations of the foundations, I see the necessity for tiny but very basic resurrections.

            When I tried to explain why discrete and in particular digital models are superior, I did not hide that any belonging abstraction and in particular linearizing implies a loss of realism. I do not yet see any possibility to decide whether or not the world is anyhow discrete at the lowest level. However, most likely such lower end of our scales for temporal and spatial distance would be as useless as an upper end. I never dealt with or believed in the big bang.

            Already when I was a child, I did not understand those who spoke of blowing up a point. To me numbers and continua are likewise abstract notions that do not have exact correlates in nature unless we define for instance how to count a pregnant cow. My Fig. 1 might illustrate how to imagine discrete values to be seen in a continuous function and how a non-linear transformation changes the scales. When I heard for the first time the expression negative signal to noise ratio, I was confused. How can it be negative? The answer is simple: SNR is usually given in dB.

            Best regards,

            Eckard

            Dear Eckard,

            I enjoyed the ideas in this essay. We are very much on the same line. Quantities are related to objects, negative and complex numbers are useful because they represent orientations of real objects. They represent common sense reality, nothing magical about them. We could do without complex numbers and replace them with their 3D analogs, the more powerful quaternions.

            I remember you also used examples of auditory perception in last year's essay to make your point.

            I especially liked the sentences:

            "Strictly speaking there are neither absolutely continuous nor absolutely discrete signals, because any tangible thing is finite."

            "Even begin and end of an animal's life are continuous while irreversible processes."

            "Peas are preferably treated as if they were uncountable. Uncountable liquids are measured in terms of countable gallons."

            "Both the foundations of mathematics and, to a larger extent, basic interpretations of implication for physics are not yet as mature as possible."

            "...unfortunately common identification of a number with just one point instead of the distance between zero and a virtual limit point..."

            "Foundational pragmatism outperforms pseudo-foundational formalism"

            Best wishes for this contest,

            Arjen

              Dear Georgina,

              Be not worried if I got anonymous. It costs me time to login. Nonetheless I did so again. The system seems to tend logging me out.

              I apologize for not reading most of the many responses you got. Admittedly I am a bit disappointed because you did not as clearly issue against spacetime as I hoped you to do.

              Edwin Klingman asked me about the same as did you: How to interpret ict and ih. Concerning the latter see my essay. What about ict and spacetime, I seem to be the only one here who claims that physics must get rid of the Janus head of a mathematics that claims to fit reality from minus infinity to plus infinity. This would not even fit to the big bang.

              I do not understand what exactly you meant with spatial change over time. Engineers like me have to understand their tools. Complex plane is a tool to me, not an extension of numbers. Already Bombelli wrote that a+bi always comes together with its complex conjugate a-bi. In order to get only a+bi, one has to arbitrarily omit the latter. Of course, complex calculus is utterly advantageous - provided one does either not forget to go back into the domain of reality or a complex solution can reasonably be interpreted, e.g. complex impedance Z = R +i omega L.

              Best regards,

              Dear Arjen,

              Even John Baez confirmed in principle that quantum physics can equivalently be expressed in terms of real or complex numbers, and quaternions and octonions.

              However, so far he did not even mention the - as I maintain - reasonable tailor-made description in terms or only positive real numbers (R).

              My argument is simple: Any finite interval in R can be completely shifted into R, and this shift merely reverses the original physical relationship. For instance, any analysis of measured data has nothing to do with what will possibly happen after the measurement.

              Some consequences imply a lot. For instance, there is presumably no a priori given block of spacetime, no Higgs boson and no SUSY. MP3 works well with cosine transformation. This does however not mean that negative and complex numbers are unnecessary. On the contrary, they are utterly advantageous if correctly used and interpreted.

              Dear Peter,

              I did not yet read what you just wrote in your string. Time travel is impossible to me. What about the somewhat simplistic explanation you gave by means the metaphor of a river, it did not yet immediately convince me. With acoustic waves in a single medium one can also not exceed the velocity of sound by means of superposition.

              You might read what Tom Van Flandern wrote: "Is faster-than-ligth propagation allowed by the laws of physics?" and "Lorentz Contraction" in http://metaresearch.org/cosmology/gravity/LR.asp .

              Does it agree with your ideas? I see it agreeable with logic and all pertaining experiments I am aware of. It also seems to agree with the many convincing arguments collected by Ekkehard Friebe.

              Yan Flandern recognizes a universal time, a universal instant of now. Lorentz transformation works just one way and therefore without paradoxes. Minkowski metric seems to loose its basis. Physics becomes less mystic, and my touch stone seems to work: We do perhaps no longer need ict.

              Dear Eckard,

              I am very pleased with your new found popularity. Hope your essay makes it to the panel, as it appears it will. I am equally (if not even more) pleased, but not with my rating position (38) of my essay. But rather, by a very significant result I just posted yesterday. I consider you a friend and a supporter. So I just had to tell you of this directly.

              Two very key assumptions in physics (dating back to Einstein) are

              1)The constant speed of light (CSL)

              2)The Photon Hypothesis (PH)

              The first lead to Relativity, while the second lead eventually to Quantum Physics.

              In my very short paper "If the speed of light is constant, then light is a wave" I give a simple mathematical proof that CSL contradicts PH.

              I look forward to your always insightful comments.

              Best Wishes,

              Constantinos
