HOW EINSTEIN USED MAXWELL
According to Maxwell's theory, (1) the speed of light is independent
of the speed of the emitter but (2) it does depend on the speed of the observer: http://www.pitt.edu/~jdnorton/papers/companion.doc John Norton: "Einstein's second postulate, the light postulate, asserts that "light is always propagated in empty space with a definite velocity c which is independent of the state of motion of the emitting body." Einstein gave no justification for this postulate in the introduction to his paper. Its strongest justification came from Maxwell's electrodynamics. That theory had identified light with waves propagating in an electromagnetic field and concluded that just one speed was possible for them in empty space, c = 300,000 km/sec, no matter what the motion of the emitter." http://www.futura-sciences.com/fr/do...509/c3/221/p5/ "Les équations de Maxwell prévoyaient la propagation de la lumière à la vitesse de 300.000 km/s par rapport à l'éther. Or, si l'on cherche à calculer la vitesse de la lumière par rapport à un référentiel qui est lui-même mobile dans l'éther, on observe que la lumière se propage avec une vitesse différente..." http://www.solidarity-us.org/node/58 "Maxwell's theory of electricity and magnetism provides a successful framework with which to study light. In this theory light is an electromagnetic wave. Using Maxwell's equations one can compute the speed of light. One finds that the speed of light is 300,000,000 meters (186,000 miles) per second. The question arises: which inertial observer is this speed of light relative to? As in the previous paragraph, two inertial observers traveling relative to each other should observe DIFFERENT SPEEDS FOR THE SAME LIGHT WAVE." In 1905 Einstein adopted the former assertion of Maxwell's theory (the speed of light is independent of the speed of the emitter) and, by applying the principle of relativity, inferred that the speed of light is independent of the speed of the observer as well. Einstein could have adopted the latter assertion of Maxwell's theory (the speed of light does depend on the speed of the observer). Then, by applying the principle of relativity, he would have inferred that the speed of light does depend on the speed of the emitter as well. This would have been a return to Newton's emission theory of light: http://www.mfo.de/programme/schedule...WR_2006_10.pdf Jean Eisenstaedt: "At the end of the 18th century, a natural extension of Newton's dynamics to light was developed but immediately forgotten. A body of works completed the Principia with a relativistic optics of moving bodies, the discovery of the Doppler-Fizeau effect some sixty years before Doppler, and many other effects and ideas which represent a fascinating preamble to Einstein relativities. It was simply supposed that 'a body-light', as Newton named it, was subject to the whole dynamics of the Principia in much the same way as were material particles; thus it was subject to the Galilean relativity and its velocity was supposed to be variable. Of course it was subject to the short range 'refringent' force of the corpuscular theory of light -- which is part of the Principia-- but also to the long range force of gravitation which induces Newton's theory of gravitation. The fact that the 'mass' of a corpuscle of light was not known did not constitute a problem since it does not appear in the Newtonian (or Einsteinian) equations of motion. It was precisely what John Michell (1724-1793), Robert Blair (1748-1828), Johann G. von Soldner (1776-1833) and François Arago (1786-1853) were to do at the end of the 18th century and the beginning the 19th century in the context of Newton's dynamics. Actually this 'completed' Newtonian theory of light and material corpuscle seems to have been implicitly accepted at the time. In such a Newtonian context, not only Soldner's calculation of the deviation of light in a gravitational field was understood, but also dark bodies (cousins of black holes). A natural (Galilean and thus relativistic) optics of moving bodies was also developed which easily explained aberration and implied as well the essence of what we call today the Doppler effect. Moreover, at the same time the structure of -- but also the questions raised by-- the Michelson experiment was understood. Most of this corpus has long been forgotten. The Michell-Blair-Arago effect, prior to Doppler's effect, is entirely unknown to physicists and historians. As to the influence of gravitation on light, the story was very superficially known but had never been studied in any detail. Moreover, the existence of a theory dealing with light, relativity and gravitation, embedded in Newton's Principia was completely ignored by physicists and by historians as well. But it was a simple and natural way to deal with the question of light, relativity (and gravitation) in a Newtonian context." http://ustl1.univ-lille1.fr/culture/...40/pgs/4_5.pdf Jean Eisenstaedt: "Même s'il était conscient de l'intérêt de la théorie de l'émission, Einstein n'a pas pris le chemin, totalement oublié, de Michell, de Blair, des Principia en somme. Le contexte de découverte de la relativité ignorera le XVIIIème siècle et ses racines historiques plongent au coeur du XIXème siècle. Arago, Fresnel, Fizeau, Maxwell, Mascart, Michelson, Poincaré, Lorentz en furent les principaux acteurs et l'optique ondulatoire le cadre dans lequel ces questions sont posées. Pourtant, au plan des structures physiques, l'optique relativiste des corps en mouvement de cette fin du XVIIIème est infiniment plus intéressante - et plus utile pédagogiquement - que le long cheminement qu'a imposé l'éther."

HOW EINSTEIN USED MAXWELL
You stand on the beach and the wavecrests hit your feet with frequency
F and speed V. You know that F=V/L where L is the wavelength - the distance between the crests. Then you start wading against the waves with speed v. This means that the wavecrests now hit your feet with speed (V+v); the frequency increases accordingly: F'=(V+v)/L ; F'F The above result (the speed of the wave depends on the speed of the observer) is consistent with both Maxwell's electromagnetic theory and Newton's emission theory of light if we find it reasonable to draw an analogy between ocean waves and light waves. Yet Einsteinians know that, for light waves, (V+v) is to be replaced by (c+v): a replacement which, if officially admitted, would mark the end of Einsteiniana (the speed of light VARIES with the speed of the observer). Then Einsteinians advance the most blatant lie: the wavecrests continue to hit your feet with CONSTANT speed V while the increase in frequency is accompanied with an IDIOTIC decrease in wavelength: F'=V/L' ; L'=LV/(V+v) http://sampit.geol.sc.edu/Doppler.html "Moving observer: A man is standing on the beach, watching the tide. The waves are washing into the shore and over his feet with a constant frequency and wavelength. However, if he begins walking out into the ocean, the waves will begin hitting him more frequently, leading him to perceive that the wavelength of the waves has decreased. Again, this phenomenon is due to the fact that the source and the observer are not the in the same frame of reference. Although the wavelength appears to have decreased to the man, the wavelength would appear constant to a jellyfish floating along with the tide." http://www.pitt.edu/~jdnorton/teachi...ang/index.html John Norton: "Here's a light wave and an observer. If the observer were to hurry towards the source of the light, the observer would now pass wavecrests more frequently than the resting observer. That would mean that moving observer would find the frequency of the light to have increased (AND CORRESPONDINGLY FOR THE WAVELENGTH - THE DISTANCE BETWEEN CRESTS - TO HAVE DECREASED)."

The travelling twin really is younger. http://arxiv.org/abs/physics/9807044 thus: so, if the lightwave has the "shape of a wave" -- like, give an example of an actual shape -- what is the need of Newton's God-am corpuscle? anyway, it is detected as "electrron-voltage," eV; it is just your interpretation, as its quasi-restmass.

Of couse, if you don't understand Minkowski space time in SR, thus: yeah, in a pressurized cabin. 2 eggs. thus: the geometrical term, dilation, is perfectly acceptable, because of the habitual use of Minkowski diagrams; Death to the lightcone -- long-live the lightcone-heads! I do recall reading of some testable stuff, in the argumentum over Smolin's silly book (his _Three Toads to QG_ is much less political). so, what is it that is testabley false -- what's BSRT?

HOW EINSTEIN USED MAXWELL
According to Maxwell's theory, the speed of light DOES depend on the
speed of the observer: http://www.amazon.com/Brief-History-.../dp/0553380168 Stephen Hawking: "Maxwell's theory predicted that radio or light waves should travel at a certain fixed speed. But Newton's theory had got rid of the idea of absolute rest, so if light was supposed to travel at a fixed speed, one would have to say what that fixed speed was to be measured relative to. It was therefore suggested that there was a substance called the "ether" that was present everywhere, even in "empty" space. Light waves should travel through the ether as sound waves travel through air, and their speed should therefore be relative to the ether. Different observers, moving relative to the ether, would see light coming toward them at different speeds, but light's speed relative to the ether would remain fixed." Pentcho Valev wrote: According to Maxwell's theory, (1) the speed of light is independent of the speed of the emitter but (2) it does depend on the speed of the observer: http://www.pitt.edu/~jdnorton/papers/companion.doc John Norton: "Einstein's second postulate, the light postulate, asserts that "light is always propagated in empty space with a definite velocity c which is independent of the state of motion of the emitting body." Einstein gave no justification for this postulate in the introduction to his paper. Its strongest justification came from Maxwell's electrodynamics. That theory had identified light with waves propagating in an electromagnetic field and concluded that just one speed was possible for them in empty space, c = 300,000 km/sec, no matter what the motion of the emitter." http://www.futura-sciences.com/fr/do...509/c3/221/p5/ "Les équations de Maxwell prévoyaient la propagation de la lumière à la vitesse de 300.000 km/s par rapport à l'éther.
