A Question to Brian Cox and Jeff Forshaw
http://www.guardian.co.uk/science/20...?newsfeed=true
"Ask Brian Cox and Jeff Forshaw your science questions. Professors Brian Cox and Jeff Forshaw will be answering your science questions in the Observer New Review in October" I was not able to register and post my question as a comment so I am asking it he 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. This conclusion was supported by the experimental result of Michelson and Morley, and taken at face value by Einstein." Brian Cox and Jeff Forshaw, why do you teach lies? Both Maxwell's electromagnetic theory and the Michelson-Morley experiment confirmed the fact that the speed of light VARIES WITH THE SPEED OF THE OBSERVER: http://culturesciencesphysique.ens-l..._CSP_relat.xml Gabrielle Bonnet, École Normale Supérieure de Lyon: "Les équations de Maxwell font en particulier intervenir une constante, c, qui est la vitesse de la lumière dans le vide. Par un changement de référentiel classique, si c est la vitesse de la lumière dans le vide dans un premier référentiel, et si on se place désormais dans un nouveau référentiel en translation par rapport au premier à la vitesse constante v, la lumière devrait désormais aller à la vitesse c-v si elle se déplace dans la direction et le sens de v, et à la vitesse c+v si elle se déplace dans le sens contraire." 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." http://www.pitt.edu/~jdnorton/papers/companion.doc John Norton: "These efforts were long misled by an exaggeration of the importance of one experiment, the Michelson-Morley experiment, even though Einstein later had trouble recalling if he even knew of the experiment prior to his 1905 paper. This one experiment, in isolation, has little force. Its null result happened to be fully compatible with Newton's own emission theory of light. Located in the context of late 19th century electrodynamics when ether-based, wave theories of light predominated, however, it presented a serious problem that exercised the greatest theoretician of the day." http://www.amazon.com/Relativity-Its.../dp/0486406768 "Relativity and Its Roots" By Banesh Hoffmann "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://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." The fact that the speed of light VARIES WITH THE SPEED OF THE OBSERVER is so obvious that scientists often ignore special relativity and refer to the variation explicitly: http://www.phys.uconn.edu/~gibson/No...6_3/Sec6_3.htm Professor George N. Gibson, University of Connecticut: "However, if either the source or the observer is moving, things change. This is called the Doppler effect. (...) To understand the moving observer, imagine you are in a motorboat on the ocean. If you are not moving, the boat will bob up and down with a certain frequency determined by the ocean waves coming in. However, imagine that you are moving into the waves fairly quickly. You will find that you bob up and down more rapidly, because you hit the crests of the waves sooner than if you were not moving. So, the frequency of the waves appears to be higher to you than if you were not moving. Notice, THE WAVES THEMSELVES HAVE NOT CHANGED, only your experience of them. Nevertheless, you would say that the frequency has increased. Now imagine that you are returning to shore, and so you are traveling in the same direction as the waves. In this case, the waves may still overtake you, but AT A MUCH SLOWER RATE - you will bob up and down more slowly. In fact, if you travel with exactly the same speed as the waves, you will not bob up and down at all. The same thing is true for sound waves, or ANY OTHER WAVES. If you are moving into a wave, its frequency will appear to you to be higher, while if you are traveling in the same direction as the waves, their frequency will appear to be lower. The formula for the frequency that the observer will detect depends on the speed of the observer - the larger the speed the greater the effect. If we call the speed of the observer, Vo, the frequency the observer detects will be: f'=f(1+Vo/Vwave). Here, f is the original frequency and Vwave is the speed of the wave." http://a-levelphysicstutor.com/wav-doppler.php "vO is the velocity of an observer moving towards the source. This velocity is independent of the motion of the source. Hence, the velocity of waves relative to the observer is c + vO. (...) The motion of an observer does not alter the wavelength. The increase in frequency is a result of the observer encountering more wavelengths in a given time." http://www.hep.man.ac.uk/u/roger/PHY.../lecture18.pdf Roger Barlow: "Now suppose the source is fixed but the observer is moving towards the source, with speed v. In time t, ct/(lambda) waves pass a fixed point. A moving point adds another vt/(lambda). So f'=(c +v)/(lambda)." http://www.expo-db.be/ExposPrecedent...%20Doppler.pdf "La variation de la fréquence observée lorsqu'il y a mouvement relatif entre la source et l'observateur est appelée effet Doppler. (...) 6. Source immobile - Observateur en mouvement: La distance entre les crêtes, la longueur d'onde lambda ne change pas. Mais la vitesse des crêtes par rapport à l'observateur change !"

Brian Cox: "If I was to fly past you incredibly fast, I would see your time tick much slower than mine. This idea lies at the heart of Einstein's theory of relativity. (...) According to Einstein, you should see the time tick slower at my feet than at the top of my head." Brian Cox, would you teach these "élucubrations" if you knew that (the audience knows that) both Maxwell's electromagnetic theory and the Michelson-Morley experiment confirmed the fact that the speed of light VARIES WITH THE SPEED OF THE OBSERVER?

A general point: what does it mean to babble inanities in pathetic attempt to shoot the messenger and avoid any discussion in re the physical data of MMX, dunce Williams? How come the voice of the airline hostess talking to a passenger isn't Doppler- shifted when she's hurtling through the air at 500 mph, dunce Williams who is an Einstein in confederacy against Newton? What's the answer according to your theory? The plane contracts along the fuselage but the wings remain the same length, perhaps...or maybe its a complete mystery to you. |
