George Orwell: "Crimestop means the faculty of stopping short, as though by instinct, at the threshold of any dangerous thought. It includes the power of not grasping analogies, of failing to perceive logical errors, of misunderstanding the simplest arguments if they are inimical to Ingsoc, and of being bored or repelled by any train of thought which is capable of leading in a heretical direction. Crimestop, in short, means protective stupidity." Examples of "stopping short, as though by instinct, at the threshold of any dangerous thought" and advancing some red herring which in the end camouflages the real problem: http://www.usnews.com/usnews/culture...6/26beyond.htm "Einstein postulated, first, that the laws of physics don't prefer one reference frame over another, as long as each is moving at a constant velocity. Second, he said that c, the speed of light, will appear exactly the same to every observer, in every frame of reference. A century later, that second postulate still defies common sense. It says that if you're driving down the highway at a quarter the speed of light, you'll still see the photons from your headlights racing ahead of you at light speed--not three-quarters light speed. If I'm coming from the opposite direction at half light speed, I'll still see your photons approaching at c--not 1.5 times c. Since speed is just space divided by time, and we both agree about the speed of light, we can't possibly agree about space and time. You say my clock is too slow and my yardstick has shrunk (not to mention my whole car). Maddeningly, I say the same about you. The one thing we agree on, aside from c itself, is the distance covered by the photons in the weird new reference frame of four-dimensional spacetime. It might be a relief to learn that physicists were talking about chucking this deeply strange theory. But just as Einstein made only minute corrections to Newton in everyday life--to really feel the effects of special relativity, you have to move at a large fraction of light speed--the proposed changes to relativity would have only subtle, hard-to-detect effects. Yet the stakes are big: the quest for a single theory that would unite general relativity, Einstein's later theory describing gravity, with quantum mechanics, the theory describing the forces inside the atom. Physicists are taking many paths to this "quantum gravity" grail, but in all of them spacetime itself, instead of being continuous, is made of quantum bits. "It's like the difference between sand and water," says Giovanni Amelino-Camelia of La Sapienza University in Rome-- except that the spacetime grains could be around a hundred billion billionth the size of an atomic nucleus. At this "Planck length," named after the father of quantum physics, gravity would no longer be described by general relativity but by the new theory." http://www.spacetimecenter.org/confe...2008/Henry.pdf Teaching Special Relativity: Minkowski trumps Einstein Richard Conn Henry Henry A. Rowland Department of Physics and Astronomy The Johns Hopkins University "Students find physics difficult - I am thinking of first-year undergraduate university physics majors. I found it difficult myself, and it took me almost 40 years of teaching physics to fully understand the reasons for the perceived "difficulty." Why do students who find mathematics easy to understand, find physics difficult to understand?....How grotesquely badly we teach special relativity encapsulates the practical problem of teaching physics to the freshman physics major. I have never found a single freshman physics textbook that teaches Minkowski spacetime; I have never found a single text on General Relativity that mentions "Einstein's two postulates.".....There is no doubt that, historically, Albert Einstein, in 1905, did introduce two postulates (and also, that it is he who discovered special relativity). But the second of these postulates (the one concerning the constancy of c, just in case Reese has confused you!) did not survive the year.

Cooper cites the original passage from Clausius: in choosing the word "Entropy," Clausius wrote: "I prefer going to the ancient languages for the names of important scientific quantities, so that they mean the same thing in all living tongues. I propose, accordingly, to call S the entropy of a body, after the Greek word "transformation." I have designedly coined the word entropy to be similar to energy, for these two quantities are so analogous in their physical significance, that an analogy of denominations seems to be helpful." Right after quoting Clausius' explanation on his reasons for the choice of the word "Entropy," Cooper commented: "By doing this, rather than extracting a name from the body of the current language (say: lost heat), he succeeded in coining a word that meant the same thing to everybody: nothing." I fully agree with Coopers comment; however, I have two additional comments, and contrary to Cooper, I venture into taking the inevitable conclusion: First, I agree that "entropy means the same thing to everybody: nothing." But more than that, entropy is also a misleading term....Finally, I believe that the time has come to reach the inevitable conclusion that “entropy” is a misnomer and should be replaced by either missing information or uncertainty."

More examples of "stopping short, as though by instinct, at the threshold of any dangerous thought" and advancing some red herring which in the end camouflages the falsehood of Einstein's 1905 light postulate: http://philsci-archive.pitt.edu/arch...ontraction.pdf Harvey Brown: "The FitzGerald-Lorentz (FL) hypothesis was of course the result of a somewhat desperate attempt to reconcile the null result of the 1887 Michelson-Morley (MM) experiment with the hitherto successful Fresnel-Lorentz theory of a stationary luminiferous ether, a medium through which the earth is assumed to move with unappreciable drag. The MM experiment is rightly regarded today as one of the turning points in physics, and although it is discussed widely in textbooks, it is remarkable how much confusion still surrounds its structure and meaning. In order then to understand the FL hypothesis, it is necessary first to go over some welltrodden ground; sections 2 and 3 below are designed to show what the 1887 null result does and does not imply. In particular it is shown in section 3 that IN THE CONTEXT OF A THEORY OF LIGHT IN WHICH THE LIGHT-SPEED IS INDEPENDENT OF THE SPEED OF THE SOURCE, A CERTAIN MOTION-INDUCED DEFORMATION OF RIGID BODIES, OF WHICH CONTRACTION IS A SPECIAL CASE, IS REQUIRED." http://philsci-archive.pitt.edu/arch.../Minkowski.pdf "Minkowski space-time: a glorious non-entity" Harvey R. Brown and Oliver Pooley: "An examination of the status of length contraction in the context of Einstein’s 1905 treatment of SR will illustrate the way in which principle theories fail to be explanatory. Recall that in this derivation the first conclusion drawn from the two fundamental postulates is the invariance of the speed of light, that it has the same constant value in all inertial frames. This gives the ‘k-Lorentz transformations’, the Lorentz transformations up to a velocity dependent scale factor, k. What has, in effect, been shown is that if the speed of light as measured with respect to frame F0 is to be found to be the same value as when measured with respect to the ‘resting frame’ F, then rods and clocks at rest in F0 had better contract and dilate (with respect to frame F) in the coordinated way that is encoded in the k-Lorentz transformations. One then appeals to the relativity principle again— the principle entails that these coordinated contractions and dilations must be exactly the same function of velocity for each inertial frame, along with the principle of spatial isotropy, in order to narrow down the deformations to just those encoded in the Lorentz transformations. What has been shown is that rods and clocks must behave in quite particular ways in order for the two postulates to be true together. But this hardly amounts to an explanation of such behaviour. Rather things go the other way around. It is because rods and clocks behave as they do, in a way that is consistent with the relativity principle, that light is measured to have the same speed in each inertial frame." http://www.pitt.edu/~jdnorton/teachi...hys/index.html John Norton: "Neo-Lorentzians return again. A perennial topic of debate is whether the physical effects of special relativity (e.g. length contraction) require some sort of physical explanation that in turn requires some sort of state of rest such as Lorentz envisaged was supplied by his ether." http://www.newscientist.com/article/...erse-tick.html "General relativity knits together space, time and gravity. Confounding all common sense, how time passes in Einstein's universe depends on what you are doing and where you are. Clocks run faster when the pull of gravity is weaker, so if you live up a skyscraper you age ever so slightly faster than you would if you lived on the ground floor, where Earth's gravitational tug is stronger. "General relativity completely changed our understanding of time," says Carlo Rovelli, a theoretical physicist at the University of the Mediterranean in Marseille, France.....It is still not clear who is right, says John Norton, a philosopher based at the University of Pittsburgh, Pennsylvania. Norton is hesitant to express it, but his instinct - and the consensus in physics - seems to be that space and time exist on their own. The trouble with this idea, though, is that it doesn't sit well with relativity, which describes space-time as a malleable fabric whose geometry can be changed by the gravity of stars, planets and matter." http://www.pitt.edu/~jdnorton/Goodie...age/index.html John Norton, 1 Mar 2009: "A common belief among philosophers of physics is that the passage of time of ordinary experience is merely an illusion. The idea is seductive since it explains away the awkward fact that our best physical theories of space and time have yet to capture this passage. I urge that we should resist the idea. We know what illusions are like and how to detect them. Passage exhibits no sign of being an illusion....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 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. There are temporal orderings. We can identify earlier and later stages of temporal processes and everything in between. What we cannot find is a passing of those stages that recapitulates the presentation of the successive moments to our consciousness, all centered on the one preferred moment of "now." At first, that seems like an extraordinary lacuna. It is, it would seem, a failure of our best physical theories of time to capture one of time's most important properties. However the longer one works with the physics, the less worrisome it becomes....I was, I confess, a happy and contented believer that passage is an illusion. It did bother me a little that we seemed to have no idea of just how the news of the moments of time gets to be rationed to consciousness in such rigid doses.....Now consider the passage of time. Is there a comparable reason in the known physics of space and time to dismiss it as an illusion? I know of none. The only stimulus is a negative one. We don't find passage in our present theories and we would like to preserve the vanity that our physical theories of time have captured all the important facts of time. So we protect our vanity by the stratagem of dismissing passage as an illusion." 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." Pentcho Valev |

The theory was the most advanced physics of the time. Some 50 years before, Maxwell had shown that light was merely a ripple propagating in an electromagnetic field. Maxwell's theory predicted that the speed of the ripple was a quite definite number: c. The speed of a light signal was quite unlike the speed of a pebble, say. The pebble could move at any speed, depending on how hard it was thrown. It was different with light in Maxwell's theory. No matter how the light signal was made and projected, its speed always came out the same."

Yet that was not the correct equation: as far as its speed was concerned, light obeyed Newton's emission theory of light and behaved like a pebble, say. That is, the speed of light was again VARIABLE and obeyed the equation c'=c+v, but this equation was different since v was the relative speed of the light source and the observer." Pentcho Valev |

Crimestop, in short, means protective stupidity." Stopping short, as though by instinct, at the threshold of the dangerous thought: "Einstein's 1905 light postulate (c'=c) is false; its antithesis given by Newton's emission theory of light (c'=c+v) is true": http://www.astrofind.net/documents/t...-radiation.php The Development of Our Views on the Composition and Essence of Radiation by Albert Einstein Albert Einstein 1909: "A large body of facts shows undeniably that light has certain fundamental properties that are better explained by Newton's emission theory of light than by the oscillation theory. For this reason, I believe that the next phase in the development of theoretical physics will bring us a theory of light that can be considered a fusion of the oscillation and emission theories. The purpose of the following remarks is to justify this belief and to show that a profound change in our views on the composition and essence of light is imperative.....Then the electromagnetic fields that make up light no longer appear as a state of a hypothetical medium, but rather as independent entities that the light source gives off, just as in Newton's emission theory of light......Relativity theory has changed our views on light. Light is conceived not as a manifestation of the state of some hypothetical medium, but rather as an independent entity like matter. Moreover, this theory shares with the corpuscular theory of light the unusual property that light carries inertial mass from the emitting to the absorbing object." http://www.pitt.edu/~jdnorton/papers/companion.doc John Norton: "Einstein could not see how to formulate a fully relativistic electrodynamics merely using his new device of field transformations. So he considered the possibility of modifying Maxwell's electrodynamics in order to bring it into accord with an emission theory of light, such as Newton had originally conceived. There was some inevitability in these attempts, as long as he held to classical (Galilean) kinematics. Imagine that some emitter sends out a light beam at c. According to this kinematics, an observer who moves past at v in the opposite direction, will see the emitter moving at v and the light emitted at c+v. This last fact is the defining characteristic of an emission theory of light: the velocity of the emitter is added vectorially to the velocity of light emitted....If an emission theory can be formulated as a field theory, it would seem to be unable to determine the future course of processes from their state in the present. AS LONG AS EINSTEIN EXPECTED A VIABLE THEORY LIGHT, ELECTRICITY AND MAGNETISM TO BE A FIELD THEORY, these sorts of objections would render an EMISSION THEORY OF LIGHT INADMISSIBLE." 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." Albert Einstein 1954: "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." http://au.encarta.msn.com/sidebar_78...merican.h tml Albert Einstein 1950: "Since the theory of general relativity implies the representation of physical reality by a CONTINUOUS FIELD, the concept of particles or material points cannot play a fundamental part, nor can the concept of motion. The particle can only appear as a limited region in space in which the field strength or the energy density are particularly high." http://books.google.com/books?id=JokgnS1JtmMC "Relativity and Its Roots" By Banesh Hoffmann p.92: "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."

George Orwell: "Crimestop means the faculty of stopping short, as though by instinct, at the threshold of any dangerous thought. It includes the power of not grasping analogies, of failing to perceive logical errors, of misunderstanding the simplest arguments if they are inimical to Ingsoc, and of being bored or repelled by any train of thought which is capable of leading in a heretical direction. Crimestop, in short, means protective stupidity." http://www.liferesearchuniversal.com...html#twentytwo George Orwell: "He set to work to exercise himself in crimestop.

Stupidity was as necessary as intelligence, and as difficult to attain." Einsteinians exercising themselves in crimestop by presenting themselves with the proposition: The Michelson-Morley experiment "showed that the speed of light is always the same (now known to be 186,282 miles per second) relative to stationary observers as well as moving ones": http://www.newsweek.com/id/204892 "On July 22 the Einstein Papers Project, located at the California Institute of Technology in Pasadena, will release the 12th volume of letters written or received by Albert Einstein - 791 of them - plus transcripts of several notable lectures and interviews the physicist gave, covering the year 1921. It was a momentous 12 months. You might think there are no new revelations to be made about him, but for Einstein groupies the current volume addresses at least one key question: what did Einstein know about an 1887 experiment that discovered that the speed of light is invariant, regardless of the observer's speed or direction of motion - an idea that forms the core of special relativity and that Einstein did not mention when he laid out the theory of special relativity in a 1905 paper? Called the Michelson-Morley experiment, it disproved the existence of the ether, a substance once thought to carry light waves and form an absolute reference frame for space. In their namesake experiment, Albert Michelson (a physicist who won the Nobel Prize in 1907) and Edward Morley (a chemist) showed that the speed of light is always the same (now known to be 186,282 miles per second) relative to stationary observers as well as moving ones." However stupidity is "as necessary as intelligence, and as difficult to attain". The same Einsteinians (more precisely, John Norton is an Editor of the Einstein Papers Project) attaining utmost intelligence: http://philsci-archive.pitt.edu/arch.../02/Norton.pdf John Norton: "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......THE MICHELSON-MORLEY EXPERIMENT IS FULLY COMPATIBLE WITH AN EMISSION THEORY OF LIGHT THAT CONTRADICTS THE LIGHT POSTULATE." http://books.google.com/books?id=JokgnS1JtmMC "Relativity and Its Roots" By Banesh Hoffmann p.92: "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." James H. Smith "Introduction à la relativité" EDISCIENCE 1969 pp. 39-41: "Si la lumière était un flot de particules mécaniques obéissant aux lois de la mécanique, il n'y aurait aucune difficulté à comprendre les résultats de l'expérience de Michelson-Morley.... Supposons, par exemple, qu'une fusée se déplace avec une vitesse (1/2)c par rapport à un observateur et qu'un rayon de lumière parte de son nez. Si la vitesse de la lumière signifiait vitesse des "particules" de la lumière par rapport à leur source, alors ces "particules" de lumière se déplaceraient à la vitesse c/2+c=(3/2)c par rapport à l'observateur. Mais ce comportement ne ressemble pas du tout à celui d'une onde, car les ondes se propagent à une certaine vitesse par rapport au milieu dans lequel elles se développent et non pas à une certaine vitesse par rapport à leur source..... Il nous faut insister sur le fait suivant: QUAND EINSTEIN PROPOSA QUE LA VITESSE DE LA LUMIERE SOIT INDEPENDANTE DE CELLE DE LA SOURCE, IL N'EN EXISTAIT AUCUNE PREUVE EXPERIMENTALE. IL LE POSTULA PAR PURE NECESSITE LOGIQUE." Pentcho Valev |
