THE END OF SCIENCE
http://arc-tv.com/the-crisis-in-physics-and-its-cause/
"However, for the past century, theoretical physicists have been sending a different message. They have rejected causality in favor of chance, logic in favor of contradictions, and reality in favor of fantasy. The science of physics is now riddled with claims that are as absurd as those of any religious cult." http://school.maths.uwa.edu.au/~mike/Trouble.doc Mike Alder: "It is easy to see the consequences of the takeover by the bureaucrats. Bureaucrats favour uniformity, it simplifies their lives. They want rules to follow. They prefer the dead to the living. They have taken over religions, the universities and now they are taking over Science. And they are killing it in the process. The forms and rituals remain, but the spirit is dead. The cold frozen corpse is so much more appealing to the bureaucratic mind-set than the living spirit of the quest for insight. Bureaucracies put a premium on the old being in charge, which puts a stop to innovation. Something perhaps will remain, but it will no longer attract the best minds. This, essentially, is the Smolin position. He gives details and examples of the death of Physics, although he, being American, is optimistic that it can be reversed. I am not. (...) Developing ideas and applying them is done by a certain kind of temperament in a certain kind of setting, one where there is a good deal of personal freedom and a willingness to take risks. No doubt we still have the people. But the setting is gone and will not come back. Science is a product of the renaissance and an entrepreneurial spirit. It will not survive the triumph of bureacracy. Despite having the infrastructure, China never developed Science. And soon the West won't have it either." http://www.wickedlocal.com/pembroke/...lton-Ratcliffe Hilton Ratcliffe: "Physics is dying, being suffocated by meta- mathematics, and physics departments at major universities with grand histories in physical science are closing down for lack of interest. It is a crisis in my view. (...) If, as in the case of GTR and later with Big Bang Theory and Black Hole theory, the protagonists have seductive charisma (which Einstein, Gamow, and Hawking, respectively, had in abundance) then the theory, though not the least bit understood, becomes the darling of the media. GTR and Big Bang Theory are sacrosanct, and it's most certainly not because they make any sense. In fact, they have become the measure by which we sanctify nonsense." http://www.guardian.co.uk/science/20.../22/schools.g2 "But instead of celebrating, physicists are in mourning after a report showed a dramatic decline in the number of pupils studying physics at school. The number taking A-level physics has dropped by 38% over the past 15 years, a catastrophic meltdown that is set to continue over the next few years. The report warns that a shortage of physics teachers and a lack of interest from pupils could mean the end of physics in state schools. Thereafter, physics would be restricted to only those students who could afford to go to posh schools. Britain was the home of Isaac Newton, Michael Faraday and Paul Dirac, and Brits made world-class contributions to understanding gravity, quantum physics and electromagnetism - and yet the British physicist is now facing extinction. But so what? Physicists are not as cuddly as pandas, so who cares if we disappear?" http://www.nature.com/nature/journal...l/433218a.html John Barrow: "EINSTEIN RESTORED FAITH IN THE UNINTELLIGIBILITY OF SCIENCE. Everyone knew that Einstein had done something important in 1905 (and again in 1915) but almost nobody could tell you exactly what it was. When Einstein was interviewed for a Dutch newspaper in 1921, he attributed his mass appeal to the mystery of his work for the ordinary person: "Does it make a silly impression on me, here and yonder, about my theories of which they cannot understand a word? I think it is funny and also interesting to observe. I am sure that it is the mystery of non-understanding that appeals to themit impresses them, it has the colour and the appeal of the mysterious." Relativity was a fashionable notion. It promised to sweep away old absolutist notions and refurbish science with modern ideas. In art and literature too, revolutionary changes were doing away with old conventions and standards. ALL THINGS WERE BEING MADE NEW. EINSTEIN'S RELATIVITY SUITED THE MOOD. Nobody got very excited about Einstein's brownian motion or his photoelectric effect but RELATIVITY PROMISED TO TURN THE WORLD INSIDE OUT." http://io9.com/5607692/are-physicist...up-dark-energy Dave Goldberg, Associate Professor of Physics at Drexel University: "The idea of dark energy is so ridiculous that almost every question is based on trying to make it go away. And believe me, I share your concerns. I don't want to believe in dark energy, but I have no choice. (...) Basically, if you want to get rid of dark energy, you have to get rid of relativity." http://www.nytimes.com/2010/01/26/science/26essay.html "The worrying continued. Lawrence Krauss, a cosmologist from Arizona State, said that most theories were wrong. "We get the notions they are right because we keep talking about them," he said. Not only are most theories wrong, he said, but most data are also wrong..." http://www.smithsonianmag.com/scienc.../87150187.html "Dark Energy: The Biggest Mystery in the Universe (...) "We have a complete inventory of the universe," Sean Carroll, a California Institute of Technology cosmologist, has said, "and it makes no sense." http://www.dogma.lu/txt/EK-ScienceQuiestion.htm Etienne Klein: "Votre science dit-elle réellement le vrai ? Comment osez-vous prétendre qu'elle se réfère à la rationalité alors que les jugements esthétiques, les préjugés métaphysiques et autres désirs subjectifs imprégnent sinon sa démarche tout entière, du moins certaines de ses phases ? Votre légitimité incontestée est-elle fondée sur autre chose que des effets de pouvoir ? Les mythes, que vous méprisez, ne disent-ils pas eux aussi une part de la vérité ? Le relativisme bénéficie, sous toutes ses formes, d'une sympathie intellectuelle quasi-spontanée. Pourquoi séduit-il tant ceux qui s'interrogent sur la portée des discours de la science ? Sans doute parce que, abusivement interprété comme une remise en cause des prétentions de cette dernière, il semble nourrir un soupçon qui se généralise, celui de l'imposture : « Finalement, (là comme ailleurs) tout est relatif. » (...) Comment inciter ceux qui ne connaissent pas la science à vouloir la connaître ? Comment convertir le droit de savoir, légitime mais gratuit en termes d'effort, en désir de connaître, qui, lui, demande un engagement chronophage et un véritable travail personnel ? Et comment inciter les moins intéressés d'entre nous à se tourner vers les scientifiques pour les questionner : " Que faites-vous au juste ? Que savez-vous exactement ? En quoi ce que vous proposez est-il pertinent pour nous ? " Réciproquement, comment obliger les experts à ne plus s'en tenir à leurs seules propres raisons et à écouter celles des autres ?" http://www.i-sem.net/press/jmll_isem_palermo.pdf Jean-Marc Lévy-Leblond: "La science souffre d'une forte perte de crédit, au sens propre comme au sens figuré : son soutien politique et économique, comme sa réputation intellectuelle et culturelle connaissent une crise grave. (...) Mais le plus grave peut-être dans la déculturation de la science se situe à l'extérieur de la recherche scientifique, à l'interface entre le milieu scientifique proprement dit et la société au sens large." http://www.archipope.net/article-12278372-6.html "Nous nous trouvons dans une période de mutation extrêmement profonde. Nous sommes en effet à la fin de la science telle que l'Occident l'a connue », tel est constat actuel que dresse Jean-Marc Lévy-Leblond, physicien théoricien, épistémologue et directeur des collections scientifiques des Editions du Seuil." http://archives.lesechos.fr/archives...077-80-ECH.htm "Physicien au CEA, professeur et auteur, Etienne Klein s'inquiète des relations de plus en plus conflictuelles entre la science et la société. (...) « Je me demande si nous aurons encore des physiciens dans trente ou quarante ans », remarque ce touche-à-tout aux multiples centres d'intérêt : la constitution de la matière, le temps, les relations entre science et philosophie. (...) Etienne Klein n'est pas optimiste. Selon lui, il se pourrait bien que l'idée de progrès soit tout bonnement « en train de mourir sous nos yeux »." http://www.inra.fr/dpenv/pdf/LevyLeblondC56.pdf Jean-Marc Lévy-Leblond: "Il est peut-être trop tard. Rien ne prouve, je le dis avec quelque gravité, que nous soyons capables d'opérer aujourd'hui ces nécessaires mutations. L'histoire, précisément, nous montre que, dans l'histoire des civilisations, les grands épisodes scientifiques sont terminés... (...) Rien ne garantit donc que dans les siècles à venir, notre civilisation, désormais mondiale, continue à garder à la science en tant que telle la place qu'elle a eue pendant quelques siècles." EXISTENTIAL QUESTION: Would science have survived if Einstein had not "resisted the temptation to account for the null result in terms of particles of light and simple, familiar Newtonian ideas, and introduced as his second postulate something that was more or less obvious when thought of in terms of waves in an ether"? http://www.amazon.com/Relativity-Its.../dp/0486406768 "Relativity and Its Roots" By Banesh Hoffmann "Moreover, if light consists of particles, as Einstein had suggested in his paper submitted just thirteen weeks before this one, the second principle seems absurd: A stone thrown from a speeding train can do far more damage than one thrown from a train at rest; the speed of the particle is not independent of the motion of the object emitting it. And if we take light to consist of particles and assume that these particles obey Newton's laws, they will conform to Newtonian relativity and thus automatically account for the null result of the Michelson-Morley experiment without recourse to contracting lengths, local time, or Lorentz transformations. Yet, as we have seen, Einstein resisted the temptation to account for the null result in terms of particles of light and simple, familiar Newtonian ideas, and introduced as his second postulate something that was more or less obvious when thought of in terms of waves in an ether." http://philsci-archive.pitt.edu/1743/2/Norton.pdf John Norton: "In addition to his work as editor of the Einstein papers in finding source material, Stachel assembled the many small clues that reveal Einstein's serious consideration of an emission theory of light; and he gave us the crucial insight that Einstein regarded the Michelson-Morley experiment as evidence for the principle of relativity, whereas later writers almost universally use it as support for the light postulate of special relativity. Even today, this point needs emphasis. The Michelson-Morley experiment is fully compatible with an emission theory of light that CONTRADICTS THE LIGHT POSTULATE." http://en.wikipedia.org/wiki/Emission_theory "Emission theory (also called emitter theory or ballistic theory of light) was a competing theory for the special theory of relativity, explaining the results of the Michelson-Morley experiment. Emission theories obey the principle of relativity by having no preferred frame for light transmission, but say that light is emitted at speed "c" relative to its source instead of applying the invariance postulate. Thus, emitter theory combines electrodynamics and mechanics with a simple Newtonian theory. Although there are still proponents of this theory outside the scientific mainstream, this theory is considered to be conclusively discredited by most scientists. The name most often associated with emission theory is Isaac Newton. In his Corpuscular theory Newton visualized light "corpuscles" being thrown off from hot bodies at a nominal speed of c with respect to the emitting object, and obeying the usual laws of Newtonian mechanics, and we then expect light to be moving towards us with a speed that is offset by the speed of the distant emitter (c ± v)." http://www.perimeterinstitute.ca/ind...ecture_id=3576 John Stachel: "Einstein discussed the other side of the particle-field dualism - get rid of fields and just have particles." EINSTEIN'S 1954 CONFESSION: "I consider it entirely possible that physics cannot be based upon the field concept, that is on continuous structures. Then nothing will remain of my whole castle in the air, including the theory of gravitation, but also nothing of the rest of contemporary physics." John Stachel's comment: "If I go down, everything goes down, ha ha, hm, ha ha ha." Clues to EINSTEIN'S 1954 CONFESSION: http://arxiv.org/ftp/physics/papers/0101/0101109.pdf "The two first articles (January and March) establish clearly a discontinuous structure of matter and light. The standard look of Einstein's SR is, on the contrary, essentially based on the continuous conception of the field." http://www.ekkehard-friebe.de/wallace.htm Bryan Wallace: "There is a popular argument that the world's oldest profession is sexual prostitution. I think that it is far more likely that the oldest profession is scientific prostitution, and that it is still alive and well, and thriving in the 20th century. I suspect that long before sex had any commercial value, the prehistoric shamans used their primitive knowledge to acquire status, wealth, and political power, in much the same way as the dominant scientific and religious politicians of our time do. (...) Because many of the dominant theories of our time do not follow the rules of science, they should more properly be labeled pseudoscience. The people who tend to believe more in theories than in the scientific method of testing theories, and who ignore the evidence against the theories they believe in, should be considered pseudoscientists and not true scientists. To the extent that the professed beliefs are based on the desire for status, wealth, or political reasons, these people are scientific prostitutes. (...) Einstein's special relativity theory with his second postulate that the speed of light in space is constant is the linchpin that holds the whole range of modern physics theories together. Shatter this postulate, and modern physics becomes an elaborate farce! (...) The speed of light is c+v. (...) I expect that the scientists of the future will consider the dominant abstract physics theories of our time in much the same light as we now consider the Medieval theories of how many angels can dance on the head of a pin or that the Earth stands still and the Universe moves around it."

THE END OF SCIENCE
How can a science be alive and sane and yet the following absurdities
(more precisely, consequences of Einstein's 1905 false constant-speed- of-light postulate) taught at universities? http://math.ucr.edu/home/baez/physic...barn_pole.html "These are the props. You own a barn, 40m long, with automatic doors at either end, that can be opened and closed simultaneously by a switch. You also have a pole, 80m long, which of course won't fit in the barn. Now someone takes the pole and tries to run (at nearly the speed of light) through the barn with the pole horizontal. Special Relativity (SR) says that a moving object is contracted in the direction of motion: this is called the Lorentz Contraction. So, if the pole is set in motion lengthwise, then it will contract in the reference frame of a stationary observer.....So, as the pole passes through the barn, there is an instant when it is completely within the barn. At that instant, you close both doors simultaneously, with your switch. Of course, you open them again pretty quickly, but at least momentarily you had the contracted pole shut up in your barn. The runner emerges from the far door unscathed.....If the doors are kept shut the rod will obviously smash into the barn door at one end. If the door withstands this the leading end of the rod will come to rest in the frame of reference of the stationary observer. There can be no such thing as a rigid rod in relativity so the trailing end will not stop immediately and the rod will be compressed beyond the amount it was Lorentz contracted. If it does not explode under the strain and it is sufficiently elastic it will come to rest and start to spring back to its natural shape but since it is too big for the barn the other end is now going to crash into the back door and the rod will be trapped IN A COMPRESSED STATE inside the barn." http://www.phys.unsw.edu.au/einstein...le_paradox.htm "The pole and barn paradox (or the ladder and garage paradox) pose the question: Is the symmetry of length contraction paradoxical? Einstein's theory of Special Relativity makes several predictions, some of which seem counter intuitive. (...) So, who is right? From Eric's point of view, he is: the pole's two ends were simultaneously (in his frame) inside the barn. From Emma's point of view, she is: the pole's two ends were never (in her frame) simultaneously inside the barn: the pole is longer than the barn. Both are right - according to their own point of view. And in relativity, there is no absolute point of view." http://www.quebecscience.qc.ca/Revolutions Stéphane Durand: "Pour mieux comprendre le phénomène de ralentissement du temps, il est préférable d'aborder un autre phénomène tout aussi paradoxal: la contraction des longueurs. Car la vitesse affecte non seulement l'écoulement du temps, mais aussi la longueur des objets. Ainsi, une fusée en mouvement apparaît plus courte que lorsqu'elle est au repos. Là aussi, plus la vitesse est grande, plus la contraction est importante. Et, comme pour le temps, les effets ne deviennent considérables qu'à des vitesses proches de celle de la lumière. Dans la vie de tous les jours, cette contraction est imperceptible. Cependant, si une fusée de 100 m passait devant nous à une vitesse proche de celle de la lumière, elle pourrait sembler ne mesurer que 50 m, ou même moins. Bien sûr, la question qui vient tout de suite à l'esprit est: «Cette contraction n'est-elle qu'une illusion?» Il semble tout à fait incroyable que le simple mouvement puisse comprimer un objet aussi rigide qu'une fusée. Et pourtant, la contraction est réelle... mais SANS COMPRESSION physique de l'objet! Ainsi, une fusée de 100 m passant à toute vitesse dans un tunnel de 60 m pourrait être entièrement contenue dans ce tunnel pendant une fraction de seconde, durant laquelle il serait possible de fermer des portes aux deux bouts! La fusée est donc réellement plus courte. Pourtant, il n'y a PAS DE COMPRESSION matérielle ou physique de l'engin." http://hyperphysics.phy-astr.gsu.edu.../bugrivet.html "The bug-rivet paradox is a variation on the twin paradox and is similar to the pole-barn paradox.....The end of the rivet hits the bottom of the hole before the head of the rivet hits the wall. So it looks like the bug is squashed.....All this is nonsense from the bug's point of view. The rivet head hits the wall when the rivet end is just 0.35 cm down in the hole! The rivet doesn't get close to the bug....The paradox is not resolved." How desperately Herbert Dingle and Jacques Maritain (who are both "unpersons" nowadays) fought the absurdity: http://articles.adsabs.harvard.edu/c...&filetype=.pdf Herbert Dingle: "...the internal consistency of the restricted relativity theory seems questionable if the postulate of the constancy of the velocity of light is given its usual interpretation... (...) These difficulties are removed if the postulate be interpreted MERELY as requiring that the velocity of light relative to its actual material source shall always be c..." http://www.worldnpa.org/pdf/abstracts/abstracts_215.pdf Herbert Dingle: "The special relativity theory requires different rates of ageing to result from motion which belongs no more to one twin than to the other: that is impossible. It is impossible to exaggerate the importance of this result, for this theory is, by common consent, "taken for granted" in Max Born's words, in all modern atomic research. and it determines the course of practically all current developments in physical science, theoretical and experimental, whether concerned with the laboratory or with the universe. (...) But it is now clear that the interpretation of those [Lorentz] equations as constituting a basis for a new kinematics, displacing that of Galileo and Newton, which is the essence of the special relativity theory, leads inevitably to impossibilities and therefore cannot be true. Either there is an absolute standard of rest - call it the ether as with Maxwell. or the universe as with Mach, or absolute space as with Newton, or what you will or else ALL MOTION, INCLUDING THAT WITH THE SPEED OF LIGHT, IS RELATIVE, AS WITH RITZ." http://www.amazon.ca/Oeuvres-compl%C.../dp/2850492752 Jacques Maritain, Raïssa Maritain, Jean-Marie Allion Oeuvres complètes, Volume 3, pp. 275-276: Jacques Maritain: "Ce qui est absurde, c'est d'imposer au temps réel et à la simultanéité réelle une relativité qui est le propre des relations de raison variant avec l'observateur, et de prétendre que la distance qui sépare deux événements dans le temps, ou deux points dans l'espace, prise dans ce qui la constitue intrinsèquement, soit ceci ou cela selon l'observateur, que deux événements soient réellement simultanés ou réellement successifs à raison du mouvement de l'observateur ; bref que le changement de mesure provenant du changement de l'observateur affecte la réalité même de la chose mesurée." http://www.amazon.ca/Oeuvres-compl%C.../dp/2850492752 Jacques Maritain, Raïssa Maritain, Jean-Marie Allion Oeuvres complètes, Volume 3, p. 285: Jacques Maritain: "Il ne reste plus alors qu'à avouer que la théorie [d'Einstein], si l'on donnait une signification ontologiquement réelle aux entités qu'elle met en jeu, comporterait des absurdités; entièrement logique et cohérente comme système hypothético-déductif et synthèse mathématique des phénomènes, elle n'est pas, malgré les prétensions de ses partisans, une philosophie de la nature, parce que le principe de la constance de la vitesse de la lumière, sur lequel elle s'appuie, ne peut pas être ontologiquement vrai." http://www.liferesearchuniversal.com/1984-4.html George Orwell: "Withers, however, was already an unperson. He did not exist : he had never existed." Pentcho Valev |

THE END OF SCIENCE
http://hiltonratcliffe.com/blog/?p=66
Hilton Ratcliffe: "A few years ago, I had the great privilege of sharing a supper table with some of the finest scientific minds of my era. Directly opposite me sat Professor Huseyin Yilmaz, formerly of the Institute for Advanced Studies at Princeton University, a hallowed and ivy-decked place where Albert Einstein had spent his later, introspective years. To his left sat the larger-than-life Professor Carroll Alley, Yilmaz's experimentalist colleague from the University of Maryland. On my right was the quietly spoken, amiable Professor Harold Puthoff, a director of the Institute for Advanced Studies at Austin in Texas. Dr Puthoff has achieved a fair measure of notoriety for his work on anti-gravity and the Zero Point Field, but that doesn't frighten me in the least. What did overawe me was the enormous scientific stature of these gentlemen, but I needn't have worried. They were to a fault courteous and accommodating, and entertained my dumb questions with remarkable patience. The conversation, once we had come to terms with the unfamiliar cuisine, was about Relativity. (...) Here were people discussing with great insight and authority the mathematical implications of the field equations in General Relativity. What's more (to my great astonishment) it sounded distinctly like they were suggesting improvements to the Gospel! I could contain myself no longer. "Professor Yilmaz," I said, glancing furtively around the room and then dropping my voice to a whisper, "does that mean Einstein was wrong?" All three gentlemen laughed spontaneously at my obvious discomfort, and Hal Puthoff put his hand good-naturedly on my shoulder. "Hilton," he said, "you don't have to hide under the table. It's no longer controversial to say that Einstein made mistakes. Most physicists accept that quite openly now." I had learned one of the most valuable lessons of my life." Kuhn would say the situation in science is pre-revolutionary, with anomalies in the leading theory accumulating and being openly discussed. He would be wrong. An internet search would show that the "finest scientific minds" have abandoned Einstein's relativity long ago. No serious discussions, no conferences, no seminars, nothing. Science is simply dead and scientists feel that exhumation would be pointless. Even explicit references to the falsehood of Einstein's 1905 constant-speed-of-light postulate, e.g. "The Michelson-Morley experiment is fully compatible with an emission theory of light that CONTRADICTS THE LIGHT POSTULATE", evoke no interest: http://www.pitt.edu/~jdnorton/papers/companion.doc John Norton: "These efforts were long misled by an exaggeration of the importance of one experiment, the Michelson-Morley experiment, even though Einstein later had trouble recalling if he even knew of the experiment prior to his 1905 paper. This one experiment, in isolation, has little force. Its null result happened to be fully compatible with Newton's own emission theory of light. Located in the context of late 19th century electrodynamics when ether-based, wave theories of light predominated, however, it presented a serious problem that exercised the greatest theoretician of the day." http://philsci-archive.pitt.edu/1743/2/Norton.pdf John Norton: "In addition to his work as editor of the Einstein papers in finding source material, Stachel assembled the many small clues that reveal Einstein's serious consideration of an emission theory of light; and he gave us the crucial insight that Einstein regarded the Michelson-Morley experiment as evidence for the principle of relativity, whereas later writers almost universally use it as support for the light postulate of special relativity. Even today, this point needs emphasis. The Michelson-Morley experiment is fully compatible with an emission theory of light that CONTRADICTS THE LIGHT POSTULATE." http://blog.hasslberger.com/Dingle_S...Crossroads.pdf Herbert Dingle, p. 59: "In closing this valuable discussion, may I, avoiding further controversy, state two indisputable and vitally important facts which it has elicited? 1. I have asked for an answer in one sentence to the question: What is it, on Einstein's theory, that distinguishes which of two similar relatively uniformly moving clocks lags behind the other (to use the translation of Einstein's own words) by an amount that increases regularly with time? Lorentz answered: its velocity through the ether, the faster moving clock working at the slower rate. Ritz answered: nothing, for there is no lag. Neither of these answers is possible to Einstein, and no one has told me of a substitute that is permitted by his theory, despite my repetition of the question and the fact that without an answer the theory is invalid." http://homepage.ntlworld.com/academ/...elativity.html What is wrong with relativity? G. BURNISTON BROWN Bulletin of the Institute of Physics and Physical Society, Vol. 18 (March, 1967) pp.7177 "A more intriguing instance of this so-called 'time dilation' is the well-known 'twin paradox', where one of two twins goes for a journey and returns to find himself younger than his brother who remained behind. This case allows more scope for muddled thinking because acceleration can be brought into the discussion. Einstein maintained the greater youthfulness of the travelling twin, and admitted that it contradicts the principle of relativity, saying that acceleration must be the cause (Einstein 1918). In this he has been followed by relativists in a long controversy in many journals, much of which ably sustains the character of earlier speculations which Born describes as "monstrous" (Born 1956). Surely there are three conclusive reasons why acceleration can have nothing to do with the time dilation calculated: (i) By taking a sufficiently long journey the effects of acceleration at the start, turn-round and end could be made negligible compared with the uniform velocity time dilation which is proportional to the duration of the journey. (ii) If there is no uniform time dilation, and the effect, if any, is due to acceleration, then the use of a formula depending only on the steady velocity and its duration cannot be justified. (iii) There is, in principle, no need for acceleration. Twin A can get his velocity V before synchronizing his clock with that of twin B as he passes. He need not turn round: he could be passed by C who has a velocity V in the opposite direction, and who adjusts his clock to that of A as he passes. When C later passes B they can compare clock readings. As far as the theoretical experiment is concerned, C's clock can be considered to be A's clock returning without acceleration since, by hypothesis, all the clocks have the same rate when at rest together and change with motion in the same way independently of direction. [fn. I am indebted to Lord Halsbury for pointing this out to me.] (...) The three examples which have been dealt with above show clearly that the difficulties are not paradoxes) but genuine contradictions which follow inevitably from the principle of relativity and the physical interpretations of the Lorentz transformations. The special theory of relativity is therefore untenable as a physical theory." http://www.informaworld.com/smpp/con...ent=a909857880 Peter Hayes "The Ideology of Relativity: The Case of the Clock Paradox" : Social Epistemology, Volume 23, Issue 1 January 2009, pages 57-78 "This first appearance of what has become known as time dilation in Einstein's work requires careful attention. In particular, anyone who assumes that the special theory deals only with uniform movement in a straight line and is thus a precisely delineated subset of the later general theory, will wish to explore why Einstein extends his conclusions to polygonal and circular movements. It is by no means "at once apparent" that what is true for a straight line is true for a polygon, nor that what has been "proved" for a polygon applies to a circle. The principle of relativity introduced at the outset of the 1905 paper implicitly limited the special theory to reference frames moving at a constant speed in a straight line with respect to one another. In later work, Einstein explicitly stated that the special theory applied only to a reference frame "in a state of uniform rectilinear and non rotary motion" in respect of a second reference frame, in contrast to the general theory that dealt with reference frames regardless of their state of motion (Einstein 1920, 61). Acceleration, therefore, would appear to be the province of the general theory. A polygon, however, would seem to necessarily involve acceleration whenever there is a abrupt alteration in the direction of travel. Even more confusingly, a circular path, far from allowing movement at a "constant velocity", has a velocity that continually changes. Einstein, it is argued, wished to minimise the significance of acceleration - as he did not mention acceleration at all in the passage, he could hardly be said to do otherwise (Essen 1971, 13). With respect to the transition from the straight line to the polygon, this assumption is corroborated by comments Einstein made in 1911 when he said that the larger the polygon the less significant the impact of a sudden change of direction would be. Einstein 1911: "The [travelling] clock runs slower if it is in uniform motion, but if it undergoes a change of direction as a result of a jolt, then the theory of relativity does not tell us what happens. The sudden change of direction might produce a sudden change in the position of the hands of the clock. However, the longer the clock is moving rectilinearly and uniformly with a given speed in a forward motion, i.e., the larger the dimensions of the polygon, the smaller must be the effect of such a hypothetical sudden change." (Einstein et al. 1993, 354) (...) The argument that the prediction of time difference between a moving and a stationary clock violates the principle of relativity is well known. Certainly, it must have become known to Einstein, for in 1918 he created a dialogue in which "Kritikus" voiced exactly this objection (Einstein 1918). In response to this criticism, Einstein underwent a volte-face, reversing his reasoning in 1905 and 1911. The sudden change in direction of the moving clock, far from having unknown effects that needed to be minimised, was now said to provide the entire explanation for the change. Instead of imagining a moving clock travelling in a huge polygon or circle to make sudden changes in direction as insignificant as possible or the journey as smooth as possible, Einstein imagined an out and back journey. He then explained that the slow-down in the moving clock occurred during the sudden jolt when it went into reverse. (...) Given Einsteins argument in 1918, it seems inescapable that his 1905 prediction of time dilation was not, in fact, a "peculiar consequence" of his forgoing account of special relativity (Einstein 1923, 49). When it is also remembered that in 1904 Lorentz deduced the existence of "local time", it is reasonable to conclude that the prediction that the clocks would end up showing different times can be reached without entering into Einstein's reasoning on the special theory at all. The supporters of Einstein, however, generally maintain that one needs to move beyond the special theory to the general theory to understand why the times shown by the clocks would be different. However, as Einstein's prediction preceded the general theory, this argument is problematic (Lovejoy 1931, 159; Essen 1971, 14). It has been seen that: (a) in 1911 Einstein explicitly rules out the ability of the special theory of relativity to say what happened if the moving clock suddenly changed direction, and (b) in 1918 Einstein tacitly admitted that his explanation of the clock paradox in 1905 was incorrect by transforming the polygonal or circular journey of the moving clock into an out and back journey. If the general theory is necessary to explain the clock paradox, then Einstein must have (a) predicted the effects of acceleration in 1905 even though he did not incorporate them into his theory for another decade, and (b) hidden his intuition by describing a journey that discounted their significance. (...) There is, nonetheless, some divergence about how to resolve the clock paradox amongst mainstream scientists and philosophers who address the issue. The majority suggest that (a) the general theory is required to resolve the paradox because like "Kritikus" they have deduced - quite correctly - that it cannot be explained by the special theory. However, a minority believe that (b) the paradox can be explained by the special theory because they have deduced - again quite correctly - that it is incredible to suppose that only the general theory can explain a prediction ostensibly arising from the prior special theory. Each deduction, considered in isolation, is allowable within the mainstream; what is not permitted is to bring the two of them together to conclude that ( c) neither the special nor the general theory explains time dilation."

THE END OF SCIENCE
In 2001 Jos Uffink, the famous expert in the foundations of
thermodynamics, informed the scientific commmunity that the second law of thermodynamics (the version stating that the entropy always increases) is "a red herring". Uffink also quoted Clifford Truesdell's statements that thermodynamics, in its present state, is "a dismal swamp of obscurity" and "a prime example to show that physicists are not exempt from the madness of crowds": http://philsci-archive.pitt.edu/archive/00000313/ Jos Uffink: "Snow stands up for the view that exact science is, in its own right, an essential part of civilisation, and should not merely be valued for its technological applications. Anyone who does not know the Second Law of Thermodynamics, and is proud of it too, exposes oneself as a Philistine. Snow's plea will strike a chord with every physicist who has ever attended a birthday party. But his call for cultural recognition creates obligations too. Before one can claim that acquaintance with the Second Law is as indispensable to a cultural education as Macbeth or Hamlet, it should obviously be clear what this law states. This question is surprisingly difficult. The Second Law made its appearance in physics around 1850, but a half century later it was already surrounded by so much confusion that the British Association for the Advancement of Science decided to appoint a special committee with the task of providing clarity about the meaning of this law. However, its final report (Bryan 1891) did not settle the issue. Half a century later, the physicist/philosopher Bridgman still complained that there are almost as many formulations of the second law as there have been discussions of it (Bridgman 1941, p. 116). And even today, the Second Law remains so obscure that it continues to attract new efforts at clarification. A recent example is the work of Lieb and Yngvason (1999)......The historian of science and mathematician Truesdell made a detailed study of the historical development of thermodynamics in the period 1822-1854. He characterises the theory, even in its present state, as 'a dismal swamp of obscurity' (1980, p. 6) and 'a prime example to show that physicists are not exempt from the madness of crowds' (ibid. p. 8).......Clausius' verbal statement of the second law makes no sense.... All that remains is a Mosaic prohibition ; a century of philosophers and journalists have acclaimed this commandment ; a century of mathematicians have shuddered and averted their eyes from the unclean.....Seven times in the past thirty years have I tried to follow the argument Clausius offers....and seven times has it blanked and gravelled me.... I cannot explain what I cannot understand.....This summary leads to the question whether it is fruitful to see irreversibility or time-asymmetry as the essence of the second law. Is it not more straightforward, in view of the unargued statements of Kelvin, the bold claims of Clausius and the strained attempts of Planck, to give up this idea? I believe that Ehrenfest-Afanassjewa was right in her verdict that the discussion about the arrow of time as expressed in the second law of the thermodynamics is actually a red herring." If Uffink is correct, the growing set of anomalies was unbearably large in 2001 so, in accordance with Thomas Kuhn's account of scientific change, a revolution in thermodynamics must have taken place in the period 2001-2011. Has anybody witnessed this revolution? Has anybody felt even the slightest stir? How many times has Uffink's paper been commented on by excited revolutionaries? Has Uffink himself kept moving in the revolutionary direction? Harry Kroto suspects there is no hope for (science in) UK: http://www.guardian.co.uk/science/20...tion.education Harry Kroto: "The wrecking of British science....The scientific method is based on what I prefer to call the inquiring mindset. It includes all areas of human thoughtful activity that categorically eschew "belief", the enemy of rationality. This mindset is a nebulous mixture of doubt, questioning, observation, experiment and, above all, curiosity, which small children possess in spades. I would argue that it is the most important, intrinsically human quality we possess, and it is responsible for the creation of the modern, enlightened portion of the world that some of us are fortunate to inhabit. Curiously, for the majority of our youth, the educational system magically causes this capacity to disappear by adolescence.....Do I think there is any hope for UK? I am really not sure." I suspect there is no hope for (science in) Bulgaria. Pentcho Valev |

Scientists somehow feel that the Augean task of removing Einstein's
1905 false constant-speed-of-light postulate and all its absurd consequences is unaccomplishable (Einstein: "Nothing will remain of my whole castle in the air, including the theory of gravitation, but also nothing of the rest of contemporary physics"; Wallace: "Shatter this postulate, and modern physics becomes an elaborate farce!"). In a sense scientists are right in claiming that the human brain is incapable of replacing the dead corpse of science with some "new physics": http://www.france-info.com/chronique...92-81-165.html "Marc Lachièze-Rey est directeur de recherche au CNRS, au Laboratoire "Astroparticules et cosmologie" de l'Université Pars7-Denis Diderot : La physique d'aujourd'hui se fonde à la fois sur la physique quantique et sur la relativité générale, nous dit-il. Véritables systèmes de pensée, ces deux théories suggèrent deux manières différentes de voir le monde. Si notre physique ne convient pas, il faut en construire une nouvelle. Des hypothèses audacieuses sous-tendent de nouvelles théories : supersymétrie, cordes et supercordes, gravité et cosmologie quantiques, géométrie non commutative…, qui renouvellent les conceptions mêmes de l'espace et du temps, de la matière et de l'univers. Mais peut-être faut-il tout simplement admettre que nous ne disposons pas d'un cerveau suffisamment développé, capable d'accéder à une nouvelle physique ?

In a sense scientists are right in claiming that the human brain is incapable of replacing the dead corpse of science with some "new physics": To change things requires an incentive that just doesn't make itself visible to people who live off each other's reputations as the only source of authority but any resolution should not require the replacement of one tyranny with another but rather it is a sort of a nervous balance to be restored where individual satisfaction becomes a reward in itself and people want to genuinely get to the bottom of things,from a individual perspective,a community perspective and bottom line. The entire community can suffer the loss of relativity or indeed any agenda of the last few hundred years,what they can't and won't do is revisit the nuts and bolts of the original empirical agenda in the late 17th century where all the damage was done.This is not a piecemeal rearrangement of details to muddle through but a core shift to remove the methodology which must have seemed great 300 years ago but has created a tangled mess in a contemporary setting. From experience as an astronomer,and the terms between astrophysics and astronomy must diverge,many of the difficulties arise from the attempt to skip past astronomical facts like trivia and especially the attempt to diminish geometry as the language of astronomy - "The laws of Nature are written in the language of mathematics ... the symbols are triangles, circles and other geometrical figures, without whose help it is impossible to comprehend a single word." Galileo The overhaul of science where it intersects with terrestrial and celestial sciences in their raw state is a colossal task and perhaps prohibits people from actually beginning it but nothing is ever going to get done in an atmosphere where intellectual statues like Newton are not challenged or rather,how his followers don't comprehend what he actually did and why it is destructive for all sciences including the empirical approach. |

http://chronicle.com/article/Hey-Phy...-Real-/126662/
John Horgan: "Hey, Physics, Get Real! I'm not sure if I've changed or physics has changed, but the thrill is gone. Recent books by practitioner-popularizers - notably The Grand Design, by Stephen Hawking and a collaborator, the Caltech physicist Leonard Mlodinow (Bantam Books, 2010); The Hidden Reality, by Brian Greene (Alfred A. Knopf, 2011); and the forthcoming Cycles of Time: An Extraordinary New View of the Universe, by Roger Penrose (Knopf, 2011) - are leaving me peeved rather than inspired. In fact, I no longer recommend books like those to students hungry for far-out ideas from science's frontiers. I feel a little guilty knocking physics, which more than any other field lured me into science journalism three decades ago. As a teenager, I lapsed out of the Catholicism in which I was raised, but I never stopped wrestling with the riddles that religion supposedly answered. Physics provided me with a kind of scientific theology, an empirical, rational way of probing, if not solving, the mysteries of existence. Physicists were discerning deep resonances between the smallest and largest scales of reality and spinning out astonishing conjectures about our universe and even other universes. (...) I haven't entirely given up on physics." How do you decide what exactly to give up on, John Horgan? John Baez gives up on everything that seems schizophrenic to him: http://www.edge.org/q2008/q08_5.html John Baez: "On the one hand we have the Standard Model, which tries to explain all the forces except gravity, and takes quantum mechanics into account. On the other hand we have General Relativity, which tries to explain gravity, and does not take quantum mechanics into account. Both theories seem to be more or less on the right track but until we somehow fit them together, or completely discard one or both, our picture of the world will be deeply schizophrenic.....I realized I didn't have enough confidence in either theory to engage in these heated debates. I also realized that there were other questions to work on: questions where I could actually tell when I was on the right track, questions where researchers cooperate more and fight less. So, I eventually decided to quit working on quantum gravity." Pentcho Valev |

THE END OF SCIENCE
End-of-science education:
http://www.autodidactproject.org/oth...deology_2.html Ideology of/in Contemporary Physics, Jean-Marc Lévy-Leblond "In this way, major advances in modern physics, especially in relativity and quantum mechanics, have paradoxically fed an intensely irrational current. One knows the popular expression for scepticism and unconcern: 'everything is relative . . . as Einstein said' (and this is not so harmless as one would believe). At a seemingly more elaborate level, the mad attempts of Bergson to criticise and reinstate the theory of relativity within his own philosophy, even if they took place fifty years ago, still give evidence of a serious crisis in the relations between science and philosophy. (...) As far as the theories of relativity or quantum physics are concerned, the last fifty years have hardly witnessed any major evolution in their mode of presentation. Most handbooks are surprisingly similar, repeating indefinitely the same schemes of inner organisation. As a general rule, a historical or rather chronological introduction - of dubious accuracy - is followed by some philosophical reflections in which traditional dogmas are enunciated under a much more schematic and poorer form than that of their creators. Having fulfilled this first task, the author then approaches the 'strictly scientific' content of the book. It consists, in general, of purely theoretical, exaggeratedly formalistic accounts, from which references to real experiments steadily vanish. Not a single impression is left of the real procedures of scientific activity, of the dialectic between theory and practice, heuristic models and formalism, axioms and history. Modern physics appears as a collection of mathematical formulae, whose only justification is that 'they work'. Moreover, the 'examples' used to 'concretise' the knowledge are often totally unreal, and actually have the effect of making it even more abstract. Such is the case when the explanation of special relativity is based on the consideration of the entirely fictitious spatial and temporal behaviour of clocks and trains (today sometimes one speaks of rockets . . . it sounds better . . . but it is as stupid!). This kind of science fiction (which is not even funny) is the more dangerous as erases the existence of a large experimental practice, where the theory of relativity is embodied in the study of high-energy particles, involving hundreds of scientific workers, thousands of tons of steel and millions of dollars. (...) This teaching situation, even if it appears unhealthy and harmful with regard to the simple aims of training and teaching (transmission of knowledge), is however in perfect ideological harmony with the general context of modern physics. A closed arduous, forbidding education, which stresses technical manipulation more than conceptual understanding, in which neither past difficulties nor future problems in the search for knowledge appear, perfectly fulfils two essential roles: to promote hierarchisation and the 'elite' spirit on behalf of a science shown as being intrinsically difficult, to be within the reach of only a few privileged individuals; and to impose a purely operational technical concept of knowledge, far from a true conceptual understanding, which would necessarily be critical and thus would reveal the limits of this knowledge. This is why discussions about educational problems take on the form of ideological struggle. It is also why, because of the essentially political nature of the resistance to change in this field, no reformist illusions should be entertained as to the possibility of any major successes, as long as such a struggle only relies on the internal critique of scientific workers and teachers, remaining within the framework of an unchanged technical and social division of labour. (...) The very availability of an essay as this reflects the existence of a deep ideological crisis in the scientific milieu. This crisis is particularly obvious in the field of physics. It is expressed, on the one hand, by a lack of motivation on the part of many young research workers, and, on the other hand, by the efforts of readjustment and self-justification on the part of the establishment. It is characterised by a serious loss of credibility in traditional values, which before had made it possible for research workers to create acceptable self-images. (...) Average scientists do not even control the meaning of their own work. Very often, they are obscure labourers in theoretical computation or experimentation; they only have a very narrow perspective of the global process to which their work is related. Confined to a limited subject, in a specialised field, their competence is extremely restricted. It is only necessary to listen to the complaints of the previous generations' scientists on the disappearance of 'general culture' in science. In fact, the case of physics is eloquent on the subject. One can say that, until the beginning of this century, the knowledge of an average physicist had progressed in a cumulative way, including progressively the whole of previous discovery. The training of physicists demanded an almost universal knowledge in the various spheres of physics. The arrival of 'modern' physics has brought about not only the parcelling of fields of knowledge, but also the abandonment of whole areas. I have already said that important sections of nineteenthcentury physics are today excluded from the scientific knowledge of many physicists. Therefore the fields of competence are not only getting narrower, but some of them are practically vanishing altogether. If physicists no longer know about physics, a fortiori they know nothing about science! The idea of a 'scientific culture', of a 'scientific method', of a 'scientific spirit', which were common to all scientists and used to give them a large capacity for the rational understanding of all reality, have turned into huge practical jokes. True, some scientists have access to a global vision of their field or even of the social organisation of science and social ties, but that tends to depend solely on the position of power they occupy. The others, massively, are dispossessed of all mastery over their activity. They have no control, no understanding of its direction." http://www.informaworld.com/smpp/con...ent=a909857880 Peter Hayes "The Ideology of Relativity: The Case of the Clock Paradox" : Social Epistemology, Volume 23, Issue 1 January 2009, pages 57-78 Peter Hayes: "The prediction that clocks will move at different rates is particularly well known, and the problem of explaining how this can be so without violating the principle of relativity is particularly obvious. The clock paradox, however, is only one of a number of simple objections that have been raised to different aspects of Einstein's theory of relativity. (Much of this criticism is quite apart from and often predates the apparent contradiction between relativity theory and quantum mechanics.) It is rare to find any attempt at a detailed rebuttal of these criticisms by professional physicists. However, physicists do sometimes give a general response to criticisms that relativity theory is syncretic by asserting that Einstein is logically consistent, but that to explain why is so difficult that critics lack the capacity to understand the argument. In this way, the handy claim that there are unspecified, highly complex resolutions of simple apparent inconsistencies in the theory can be linked to the charge that antirelativists have only a shallow understanding of the matter, probably gleaned from misleading popular accounts of the theory. The claim that the theory of relativity is logically consistent for reasons that are too complex for non-professionals to grasp is not only convenient, but is rhetorically unassailable - as whenever a critic disproves one argument, the professional physicist can allude to another more abstruse one. Einstein's transformation of the clock paradox from a purported expression of the special theory to a purported expression of the much more complicated general theory is one example of such a defence. (...) The defence of complexity implies that the novice wishing to enter the profession of theoretical physics must accept relativity on faith. It implicitly concedes that, without an understanding of relativity theory's higher complexities, it appears illogical, which means that popular "explanations" of relativity are necessarily misleading. But given Einstein's fame, physicists do not approach the theory for the first time once they have developed their expertise. Rather, they are exposed to and probably examined on popular explanations of relativity in their early training. How are youngsters new to the discipline meant to respond to these accounts? Are they misled by false explanations and only later inculcated with true ones? What happens to those who are not misled? Are they supposed to accept relativity merely on the grounds of authority? The argument of complexity suggests that to pass the first steps necessary to join the physics profession, students must either be willing to suspend disbelief and go along with a theory that appears illogical; or fail to notice the apparent inconsistencies in the theory; or notice the inconsistencies and maintain a guilty silence in the belief that this merely shows that they are unable to understand the theory. The gatekeepers of professional physics in the universities and research institutes are disinclined to support or employ anyone who raises problems over the elementary inconsistencies of relativity. A winnowing out process has made it very difficult for critics of Einstein to achieve or maintain professional status. Relativists are then able to use the argument of authority to discredit these critics. Were relativists to admit that Einstein may have made a series of elementary logical errors, they would be faced with the embarrassing question of why this had not been noticed earlier. Under these circumstances the marginalisation of antirelativists, unjustified on scientific grounds, is eminently justifiable on grounds of realpolitik. Supporters of relativity theory have protected both the theory and their own reputations by shutting their opponents out of professional discourse." Pentcho Valev |

THE END OF SCIENCE
W. H. Newton-Smith, THE RATIONALITY OF SCIENCE, Routledge, London,
1981, p. 14: "...all physical theories in the past have had their heyday and have eventually been rejected as false. Indeed, there is inductive support for a pessimistic induction: any theory will be discovered to be false within, say 200 years of being propounded. (...) Indeed the evidence might even be held to support the conclusion that no theory that will ever be discovered by the human race is strictly speaking true. (...) The rationalist (who is a realist) is likely to respond by positing an interim goal for the scientific enterprise. This is the goal of getting nearer the truth. In this case the inductive argument outlined above is accepted but its sting is removed. For accepting that argument is compatible with maintaining that CURRENT THEORIES, while strictly speaking false, ARE GETTING NEARER THE TRUTH." The pessimistic induction is very popular among philosophers of science but it is incompatible with deductivism. Consider Einstein's 1905 constant-speed-of-light postulate: http://www.fourmilab.ch/etexts/einstein/specrel/www/ "...light is always propagated in empty space with a definite velocity c which is independent of the state of motion of the emitting body." By a theory I shall mean the deductive closure of the postulate, that is, the set of all its consequences deduced validly and in the absence of false or absurd auxiliary hypotheses. If the light postulate is true, and if the auxiliary length-contraction hypothesis advanced by FitzGerald and Lorentz was not absurd, then all the conclusions of the theory are true, and IN THIS SENSE the theory is absolutely true. If Einstein's 1905 constant-speed-of-light postulate is false, then its antithesis, the equation c'=c+v given by Newton's emission theory of light and showing how the speed of light varies with v, the speed of the emitter relative to the observer, is true: http://www.pitt.edu/~jdnorton/papers/companion.doc John Norton: "These efforts were long misled by an exaggeration of the importance of one experiment, the Michelson-Morley experiment, even though Einstein later had trouble recalling if he even knew of the experiment prior to his 1905 paper. This one experiment, in isolation, has little force. Its null result happened to be fully compatible with Newton's own emission theory of light. Located in the context of late 19th century electrodynamics when ether-based, wave theories of light predominated, however, it presented a serious problem that exercised the greatest theoretician of the day." http://philsci-archive.pitt.edu/1743/2/Norton.pdf John Norton: "In addition to his work as editor of the Einstein papers in finding source material, Stachel assembled the many small clues that reveal Einstein's serious consideration of an emission theory of light; and he gave us the crucial insight that Einstein regarded the Michelson-Morley experiment as evidence for the principle of relativity, whereas later writers almost universally use it as support for the light postulate of special relativity. Even today, this point needs emphasis. The Michelson-Morley experiment is fully compatible with an emission theory of light that CONTRADICTS THE LIGHT POSTULATE." http://www.amazon.com/Relativity-Its.../dp/0486406768 "Relativity and Its Roots" By Banesh Hoffmann "Moreover, if light consists of particles, as Einstein had suggested in his paper submitted just thirteen weeks before this one, the second principle seems absurd: A stone thrown from a speeding train can do far more damage than one thrown from a train at rest; the speed of the particle is not independent of the motion of the object emitting it. And if we take light to consist of particles and assume that these particles obey Newton's laws, they will conform to Newtonian relativity and thus automatically account for the null result of the Michelson-Morley experiment without recourse to contracting lengths, local time, or Lorentz transformations. Yet, as we have seen, Einstein resisted the temptation to account for the null result in terms of particles of light and simple, familiar Newtonian ideas, and introduced as his second postulate something that was more or less obvious when thought of in terms of waves in an ether." Then the respective Newtonian theory (the set of all consequences of the antithesis of the light postulate, c'=c+v, deduced validly and in the absence of false or absurd auxiliary hypotheses) is absolutely true in the sense that all its conclusions are true. Clearly if "deductive theory" is properly defined the pessimistic induction is unjustified. The transition from Newtonian to relativistic mechanics was either a transition from absolutely false to absolutely true or a transition from absolutely true to absolutely false. False theories die but, contrary to the pessimistic induction's prophecies, no "less false" theories replace them. Rather, their incorruptible corpses continue to grow and in the end become an essential feature of our civilization. Disappearance of the false theory's corpse would imply disappearance of the civilization itself. Pentcho Valev |

THE END OF SCIENCE
In the era of postscientism scientists are divided into two main
groups: those who are paid for their scientific activity and those who are not. In terms of respectability no real division exists: any scientist is just as insignificant as any other. Recently experts sent a clear message to the scientific community: the concept of time deduced in Einstein' special relativity is unacceptable: http://www.fqxi.org/community/articles/display/148 "Many physicists argue that time is an illusion. Lee Smolin begs to differ. (...) Smolin wishes to hold on to the reality of time. But to do so, he must overcome a major hurdle: General and special relativity seem to imply the opposite. In the classical Newtonian view, physics operated according to the ticking of an invisible universal clock. But Einstein threw out that master clock when, in his theory of special relativity, he argued that no two events are truly simultaneous unless they are causally related. If simultaneity - the notion of "now" - is relative, the universal clock must be a fiction, and time itself a proxy for the movement and change of objects in the universe. Time is literally written out of the equation. Although he has spent much of his career exploring the facets of a "timeless" universe, Smolin has become convinced that this is "deeply wrong," he says. He now believes that time is more than just a useful approximation, that it is as real as our guts tell us it is - more real, in fact, than space itself. The notion of a "real and global time" is the starting hypothesis for Smolin's new work, which he will undertake this year with two graduate students supported by a $47,500 grant from FQXi." http://www.humanamente.eu/PDF/Issue13_Paper_Norton.pdf John Norton: "It is common to dismiss the passage of time as illusory since its passage has not been captured within modern physical theories. I argue that this is a mistake. Other than the awkward fact that it does not appear in our physics, there is no indication that the passage of time is an illusion. (...) The passage of time is a real, objective fact that obtains in the world independently of us. How, you may wonder, could we think anything else? One possibility is that we might think that the passage of time is some sort of illusion, an artifact of the peculiar way that our brains interact with the world. Indeed that is just what you might think if you have spent a lot of time reading modern physics. Following from the work of Einstein, Minkowski and many more, physics has given a wonderfully powerful conception of space and time. Relativity theory, in its most perspicacious form, melds space and time together to form a four- dimensional spacetime. The study of motion in space and all other processes that unfold in them merely reduce to the study of an odd sort of geometry that prevails in spacetime. In many ways, time turns out to be just like space. In this spacetime geometry, there are differences between space and time. But a difference that somehow captures the passage of time is not to be found. There is no passage of time." http://www.fqxi.org/community/articles/display/151 "The distinction between past, present and future is only a stubbornly persistent illusion." It was none other than Einstein who uttered these words. He was speaking about how our perception of time differs from the fundamental nature of time in physics. Take our perceptions first: We have a clear sense of the present moment, what came before, and what might come after. Unfortunately, physics treats time rather differently. Einstein's theory of special relativity presents us with a four-dimensional spacetime, in which the past, present and future are already mapped out. There is no special "now," just as there's no special "here." And just like spacetime does not have a fundamental direction - forcing us to move inexorably from east to west, say - time does not flow. "You have this big gap between the time of fundamental science and the time we experience," says Craig Callender, a philosopher at the University of California, San Diego." http://hps.master.univ-paris7.fr/cours_du_temps.doc Etienne Klein: "Aujourd'hui, L'astrophysicien Thibault Damour développe à sa manière des idées qui vont dans le même sens. Selon lui, le temps qui passe (qu'il sagisse d'un fait ou de notre sentiment) est le produit de notre seule subjectivité, un effet que nous devrions au caractère irréversible de notre mise en mémoire, de sorte que la question du cours du temps relèverait non pas de la physique, mais des sciences cognitives. Il écrit : « De même que la notion de température n'a aucun sens si l'on considère un système constitué d'un petit nombre de particules, de même il est probable que la notion d'écoulement du temps n'a de sens que pour certains systèmes complexes, qui évoluent hors de l'équilibre thermodynamique, et qui gèrent d'une certaine façon les informations accumulées dans leur mémoire. » Le temps ne serait donc qu'une apparence d'ordre psychologique : « Dans le domaine d'espace-temps que nous observons, poursuit-il, nous avons l'impression qu'il s'écoule "du bas vers le haut" de l'espace-temps, alors qu'en réalité ce dernier constitue un bloc rigide qui n'est nullement orienté a priori : il ne le devient que pour nous [35]. » L'existence même d'un « cours du temps », ou d'un « passage du temps », n'est ainsi que simple apparence pour de nombreux physiciens contemporains. Certains vont même jusqu'à considérer le passage du temps comme une pure illusion, comme un produit culturel abusivement dérivé de la métaphore du fleuve. C'est en effet la conception dite de l'« univers-bloc » qui semble avoir les faveurs d'une majorité de physiciens. Dans le droit fil de la théorie de la relativité, celle-ci consiste à invoquer un univers constitué d'un continuum d'espace-temps à quatre dimensions, privé de tout flux temporel : tous les événements, qu'ils soient passés, présents et futurs, ont exactement la même réalité, de la même façon que différents lieux coexistent, en même temps et avec le même poids ontologique, dans l'espace. En d'autres termes, les notions de passé ou de futur ne sont que des notions relatives, comme celles d'Est et d'Ouest. En un sens, tout ce qui va exister existe déjà et tout ce qui a existé existe encore. L'espace-temps contient l'ensemble de l'histoire de la réalité comme la partition contient l'uvre musicale : la partition existe sous une forme statique, mais ce qu'elle contient, l'esprit humain l'appréhende généralement sous la forme d'un flux temporel." http://www.amazon.com/Relativity-Sim.../dp/0415701740 Einstein, Relativity and Absolute Simultaneity (Routledge Studies in Contemporary Philosophy) "Einstein, Relativity and Absolute Simultaneity is an anthology of original essays by an international team of leading philosophers and physicists who, on the centenary of Albert Einsteins Special Theory of Relativity, come together in this volume to reassess the contemporary paradigm of the relativistic concept of time. A great deal has changed since 1905 when Einstein proposed his Special Theory of Relativity, and this book offers a fresh reassessment of Special Relativitys relativistic concept of time in terms of epistemology, metaphysics and physics. There is no other book like this available; hence philosophers and scientists across the world will welcome its publication." "UNFORTUNATELY FOR EINSTEIN'S SPECIAL RELATIVITY, HOWEVER, ITS EPISTEMOLOGICAL AND ONTOLOGICAL ASSUMPTIONS ARE NOW SEEN TO BE QUESTIONABLE, UNJUSTIFIED, FALSE, PERHAPS EVEN ILLOGICAL." Craig Callender: "In my opinion, by far the best way for the tenser to respond to Putnam et al is to adopt the Lorentz 1915 interpretation of time dilation and Fitzgerald contraction. Lorentz attributed these effects (and hence the famous null results regarding an aether) to the Lorentz invariance of the dynamical laws governing matter and radiation, not to spacetime structure. On this view, Lorentz invariance is not a spacetime symmetry but a dynamical symmetry, and the special relativistic effects of dilation and contraction are not purely kinematical. The background spacetime is Newtonian or neo- Newtonian, not Minkowskian. Both Newtonian and neo-Newtonian spacetime include a global absolute simultaneity among their invariant structures (with Newtonian spacetime singling out one of neo-Newtonian spacetimes many preferred inertial frames as the rest frame). On this picture, there is no relativity of simultaneity and spacetime is uniquely decomposable into space and time." Has the scientific community started to look for the responsible false postulate (in a deductive theory, if a conclusion is unacceptable, some initial postulate must be false)? It hasn't. Even if it had, even if it had identified the false postulate, nothing would have changed. Science seems to be irreversibly dead. Pentcho Valev |
