Answering the following two questions IN PUBLIC may turn out to be the first step in the transition from Postscientism to Science: Does the combination of the six quotations below suggest that: (A) the speed of light does depend on the speed of the light source, in accordance with Newton's emission theory of light? (B) Einstein's 1905 light postulate (stating that the speed of light does NOT depend on the speed of the light source) has virtually killed theoretical physics? 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." http://www.academie-sciences.fr/membres/in_memoriam/Einstein/Einstein_pdf/Einstein_eloge.pdf Louis de Broglie: "Tout d'abord toute idée de "grain" se trouvait expulsée de la théorie de la Lumière : celle-ci prenait la forme d'une "théorie du champ" où le rayonnement était représenté par une répartition continue dans l'espace de grandeurs évoluant continûment au cours du temps sans qu'il fût possible de distinguer, dans les domaines spatiaux au sein desquels évoluait le champ lumineux, de très petites régions singulières où le champ serait très fortement concentré et qui fournirait une image du type corpusculaire. Ce caractère à la fois continu et ondulatoire de la lumière se trouvait prendre une forme très précise dans la théorie de Maxwell où le champ lumineux venait se confondre avec un certain type de champ électromagnétique." 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/index.php?option=com_content&task=view&id=317&Itemid=81&lecture_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://www.ekkehard-friebe.de/wallace.htm Bryan Wallace: "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." Pentcho Valev pvalev@yahoo.com
