Default SILLY OR DISHONEST EINSTEINIANS ?

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. (...) 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)."

This implies that any Einsteinian who teaches that the Michelson-Morley experiment has confirmed the constancy of the speed of light is either silly or dishonest (or both):

http://www.amazon.com/Faster-Than-Sp.../dp/0738205257
Faster Than the Speed of Light, Joao Magueijo: "A missile fired from a plane moves faster than one fired from the ground because the plane's speed adds to the missile's speed. If I throw something forward on a moving train, its speed with respect to the platform is the speed of that object plus that of the train. You might think that the same should happen to light: Light flashed from a train should travel faster. However, what the Michelson-Morley experiments showed was that this was not the case: Light always moves stubbornly at the same speed. This means that if I take a light ray and ask several observers moving with respect to each other to measure the speed of this light ray, they will all agree on the same apparent speed!"

http://www.pourlascience.fr/ewb_page...vite-26042.php
Marc Lachièze-Rey: "Mais au cours du XIXe siècle, diverses expériences, et notamment celle de Michelson et Morley, ont convaincu les physiciens que la vitesse de la lumière dans le vide est invariante. En particulier, la vitesse de la lumière ne s'ajoute ni ne se retranche à celle de sa source si celle-ci est en mouvement."

http://www.time.com/time/magazine/ar...993018,00.html
Stephen Hawking: "So if you were traveling in the same direction as the light, you would expect that its speed would appear to be lower, and if you were traveling in the opposite direction to the light, that its speed would appear to be higher. Yet a series of experiments failed to find any evidence for differences in speed due to motion through the ether. The most careful and accurate of these experiments was carried out by Albert Michelson and Edward Morley at the Case Institute in Cleveland, Ohio, in 1887......It was as if light always traveled at the same speed relative to you, no matter how you were moving."

http://www.elisabrune.com/pdf/Jumeaux.pdf
Jean-Pierre Luminet: "La vitesse de la lumière dans le vide est la même pour tous les observateurs, quel que soit leur état de mouvement - il s'agit d'un principe dont Einstein est parti pour construire sa théorie, et d'un fait observé dans les célèbres expériences de Michelson et Morley."

http://www.feynmanlectures.caltech.edu/I_15.html
The Feynman Lectures on Physics, Volume 1, Chapter 15-1: "Suppose we are riding in a car that is going at a speed u, and light from the rear is going past the car with speed c. Differentiating the first equation in (15.2) gives dx'/dt=dx/dt-u, which means that according to the Galilean transformation the apparent speed of the passing light, as we measure it in the car, should not be c but should be c-u. For instance, if the car is going 100,000 mi/sec, and the light is going 186,000 mi/sec, then apparently the light going past the car should go 86,000 mi/sec. In any case, by measuring the speed of the light going past the car (if the Galilean transformation is correct for light), one could determine the speed of the car. A number of experiments based on this general idea were performed to determine the velocity of the earth, but they all failed - they gave no velocity at all. We shall discuss one of these experiments [the Michelson-Morley experiment] in detail..."

What is the percentage of Einsteinians who teach that the Michelson-Morley experiment has confirmed the constancy of the speed of light? In my view, 99%, and the following quotation seems to support my estimate:

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."

Needless to say, if 99% of the Einsteinians teach that the Michelson-Morley experiment has confirmed the constancy of the speed of light, the lie can only have been devised by Divine Albert himself:

http://query.nytimes.com/gst/abstrac...66838A 639EDE
The New York Times, April 19, 1921: "The special relativity arose from the question of whether light had an invariable velocity in free space, he [Einstein] said. The velocity of light could only be measured relative to a body or a co-ordinate system. He sketched a co-ordinate system K to which light had a velocity C. Whether the system was in motion or not was the fundamental principle. This has been developed through the researches of Maxwell and Lorentz, the principle of the constancy of the velocity of light having been based on many of their experiments. But did it hold for only one system? he asked. He gave the example of a street and a vehicle moving on that street. If the velocity of light was C for the street was it also C for the vehicle? If a second co-ordinate system K was introduced, moving with the velocity V, did light have the velocity of C here? When the light traveled the system moved with it, so it would appear that light moved slower and the principle apparently did not hold. Many famous experiments had been made on this point. Michelson showed that relative to the moving co-ordinate system K1, the light traveled with the same velocity as relative to K, which is contrary to the above observation. How could this be reconciled? Professor Einstein asked."

Once upon a time Newton's emission theory had an advantage over Einstein's special relativity: the Michelson-Morley experiment was confirming it directly, without recourse to absurd additional assumptions:

https://webspace.utexas.edu/aam829/1...tzEinstein.pdf
Alberto Martinez: "In sum, Einstein rejected the emission hypothesis prior to 1905 not because of any direct empirical evidence against it, but because it seemed to involve too many theoretical and mathematical complications.. By contrast, Ritz was impressed by the lack of empirical evidence against the emission hypothesis, and he was not deterred by the mathematical difficulties it involved. It seemed to Ritz far more reasonable to assume, in the interest of the "economy" of scientific concepts, that the speed of light depends on the speed of its source, like any other projectile, rather than to assume or believe, with Einstein, that its speed is independent of the motion of its source even though it is not a wave in a medium; that nothing can go faster than light; that the length and mass of any body varies with its velocity; that there exist no rigid bodies; that duration and simultaneity are relative concepts; that the basic parallelogram law for the addition of velocities is not exactly valid; and so forth. Ritz commented that "it is a curious thing, worthy of remark, that only a few years ago one would have thought it sufficient to refute a theory to show that it entails even one or another of these consequences...."

http://books.google.com/books?id=JokgnS1JtmMC
"Relativity and Its Roots" by Banesh Hoffmann, p.92: "There are various remarks to be made about this second principle. For instance, if it is so obvious, how could it turn out to be part of a revolution - especially when the first principle is also a natural one? 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. If it was so obvious, though, why did he need to state it as a principle? Because, having taken from the idea of light waves in the ether the one aspect that he needed, he declared early in his paper, to quote his own words, that "the introduction of a 'luminiferous ether' will prove to be superfluous."

Silly Einsteinians are straightforward: they fly towards the spotlight at 0..75c and believe that the light somehow hits them in the faces at c, not 1.75c. They also believe that this was a prediction of Maxwell's 19th century electromagnetic theory. Needless to say, silly Einsteinians teach their beliefs to gullible audiences:

http://www.youtube.com/watch?v=Mpw68rvF4pc

http://www.amazon.com/Why-Does-mc2-S.../dp/0306817586
Why Does E=mc2?: (And Why Should We Care?), Brian Cox, Jeff Forshaw, p. 91: "...Maxwell's brilliant synthesis of the experimental results of Faraday and others strongly suggested that the speed of light should be the same for all observers."

http://www.lecture-notes.co.uk/sussk...al-relativity/
Leonard Susskind: "One of the predictions of Maxwell's equations is that the velocity of electromagnetic waves, or light, is always measured to have the same value, regardless of the frame in which it is measured."

http://www.planetastronomy.com/speci...20mars2005.htm
Françoise Balibar: "Maxwell rentre en scène : il pense que la lumière se propage dans un milieu matériel baptisé éther, ce qui est une erreur, mais il pense aussi que la lumière est un champ électromagnétique, ça c'est révolutionnaire. Il met au point ses célèbres équations dans lesquelles la vitesse de la lumière est la même dans l'éther (référentiel absolu) et dans tout autre référentiel en translation uniforme."

http://sfloccari.lycee-berthelot.fr/...relativit_.pdf
Françoise Balibar: "En effet, lors d'un changement de référentiel à un autre en translation uniforme par rapport à lui, la vitesse de la lumière (appelée ici c) ne devient pas c+V; elle reste c. Cette circonstance, résultat obligé de la théorie de la lumière développée au milieu du XIXè siècle par Maxwell...."

Clever Einsteinians are different. They are dishonest but their dishonesty often takes the form of doublethink, which means that sometimes they are able to tell the truth - to draw it "back from oblivion for just so long as it is needed":

http://ebooks.adelaide.edu.au/o/orwe...hapter2.9.html
"Doublethink means the power of holding two contradictory beliefs in one's mind simultaneously, and accepting both of them. The Party intellectual knows in which direction his memories must be altered; he therefore knows that he is playing tricks with reality; but by the exercise of doublethink he also satisfies himself that reality is not violated. The process has to be conscious, or it would not be carried out with sufficient precision, but it also has to be unconscious, or it would bring with it a feeling of falsity and hence of guilt. Doublethink lies at the very heart of Ingsoc, since the essential act of the Party is to use conscious deception while retaining the firmness of purpose that goes with complete honesty. To tell deliberate lies while genuinely believing in them, to forget any fact that has become inconvenient, and then, when it becomes necessary again, to draw it back from oblivion for just so long as it is needed, to deny the existence of objective reality and all the while to take account of the reality which one denies - all this is indispensably necessary. (...) It need hardly be said that the subtlest practitioners of doublethink are those who invented doublethink and know that it is a vast system of mental cheating. In our society, those who have the best knowledge of what is happening are also those who are furthest from seeing the world as it is. In general, the greater the understanding, the greater the delusion ; the more intelligent, the less sane.."

An example of subtle doublethink:

John Norton teaches that, according to Maxwell's theory, the speed of light relative to the observer varies with the speed of the observer, and rebukes Michio Kaku for teaching otherwise:

http://www.pitt.edu/~jdnorton/papers/Chasing.pdf
John Norton: "Finally, in an apparent eagerness to provide a seamless account, an author may end up misstating the physics. Kaku (2004, p. 45) relates how Einstein found that his aversion to frozen light was vindicated when he later learned Maxwell's theory." MICHIO KAKU: "When Einstein finally learned Maxwell's equations, he could answer the question that was continually on his mind. As he suspected, he found that there were no solutions of Maxwell's equations in which light was frozen in time. But then he discovered more. To his surprise, he found that in Maxwell's theory, light beams always traveled at the same velocity, no matter how fast you moved." JOHN NORTON AGAIN: "This is supposedly what Einstein learned as a student at the Zurich Polytechnic, where he completed his studies in 1900, well before the formulation of the special theory of relativity. Yet the results described are precisely what is not to be found in the ether based Maxwell theory Einstein would then have learned. That theory allows light to slow and be frozen in the frame of reference of a sufficiently rapidly moving observer."

John Norton teaches that the speed of light relative to the observer does not vary with the speed of the observer. He explains that this invariance is the essence of Einstein's 1905 light postulate and that Einstein took the idea from... Maxwell's theory:

http://www.pitt.edu/~jdnorton/teachi...les/index.html
John Norton: "Why Einstein should believe the light postulate is a little harder to see. We would expect that a light signal would slow down relative to us if we chase after it. The light postulate says no. No matter how fast an inertial observer is traveling in pursuit of the light signal, that observer will always find the light signal to be traveling at the same speed, c. The principal reason for Einstein's acceptance of the light postulate was his lengthy study of electrodynamics, the theory of electric and magnetic fields. 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."
