http://www.britannica.com/EBchecked/topic/496904/relativity/252878/Special-relativity ENCYCLOPAEDIA BRITANNICA TEACHING LIES: "The fact that the speed of light is the same for all observers is inexplicable in ordinary terms. If a passenger in a train moving at 100 km per hour shoots an arrow in the train’s direction of motion at 200 km per hour, a trackside observer would measure the speed of the arrow as the sum of the two speeds, or 300 km per hour (see figure). In analogy, if the train moves at the speed of light and a passenger shines a laser in the same direction, then common sense indicates that a trackside observer should see the light moving at the sum of the two speeds, or twice the speed of light (6 × 108 metres per second). While such a law of addition of velocities is valid in classical mechanics, THE MICHELSON- MORLEY EXPERIMENT SHOWED THAT LIGHT DOES NOT OBEY THIS LAW." Einsteinians who are somewhat less dishonest than those who have written Encyclopaedia Britannica: http://philsci-archive.pitt.edu/archive/00001743/02/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 pvalev@yahoo.com
