THE STATEMENT THAT ANNIHILATES EINSTEINIANA
The fatal statement is "THE MOTION OF AN OBSERVER DOES NOT ALTER THE
WAVELENGTH": 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." Einsteinians desperately exercise themselves in crimestop in order to discover the mechanism by which the motion of the observer does alter the wavelength but no success so far: http://www.liferesearchuniversal.com/1984-22 George Orwell: "He set to work to exercise himself in crimestop. He presented himself with propositions - "the Party says the earth is flat", "the party says that ice is heavier than water" - and trained himself in not seeing or not understanding the arguments that contradicted them. It was not easy. It needed great powers of reasoning and improvisation. The arithmetical problems raised, for instance, by such a statement as "two and two make five" were beyond his intellectual grasp. It needed also a sort of athleticism of mind, an ability at one moment to make the most delicate use of logic and at the next to be unconscious of the crudest logical errors. Stupidity was as necessary as intelligence, and as difficult to attain." Pentcho Valev |

"L'effet Doppler est le décalage de fréquence d'une onde acoustique ou électromagnétique entre la mesure à l'émission et la mesure à la réception lorsque la distance entre l'émetteur et le récepteur varie au cours du temps. (...) Pour comprendre ce phénomène, il s'agit de penser à une onde à une fréquence donnée qui est émise vers un observateur en mouvement, ou vis-versa. LA LONGUEUR D'ONDE DU SIGNAL EST CONSTANTE mais si l'observateur se rapproche de la source, il se déplace vers les fronts d'ondes successifs et perçoit donc plus d'ondes par seconde que s'il était resté stationnaire, donc une augmentation de la fréquence. De la même manière, s'il s'éloigne de la source, les fronts d'onde l'atteindront avec un retard qui dépend de sa vitesse d'éloignement, donc une diminution de la fréquence." Jean-Marc Lévy-Leblond?

THE STATEMENT THAT ANNIHILATES EINSTEINIANA
In order to save Divine Albert's Divine Theory, an Einsteinian
exercising himself in crimestop must be able at one moment to draw a straightforward analogy between an observer moving against sound waves and an observer moving against light waves - both pass wavecrests more frequently than a resting observer - but then to come to the idiotic conclusion that, while the motion of the observer does not alter the wavelength of sound waves, it does alter the wavelength of light waves so that the speed of the light relative to the observer can gloriously remain unchanged. The task is extremely difficult and beyond the intellectual grasp of almost all Einsteinians: http://www.liferesearchuniversal.com/1984-22 George Orwell: "He set to work to exercise himself in crimestop. He presented himself with propositions - "the Party says the earth is flat", "the party says that ice is heavier than water" - and trained himself in not seeing or not understanding the arguments that contradicted them.

It needed also a sort of athleticism of mind, an ability at one moment to make the most delicate use of logic and at the next to be unconscious of the crudest logical errors. Stupidity was as necessary as intelligence, and as difficult to attain." So far only John Norton, the cleverest Einsteinian, has managed to solve the problem without any disintegration of his soul: 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)."

Black Holes, Wormholes & Time Machines, Jim Al-Khalili pp. 49-50: "...consider a more familiar phenomenon called the Doppler shift which, as you probably know, is the change in pitch you hear when, say, a fast ambulance goes past you. The reason for this effect is the change in frequency of the sound waves which reach you from the ambulance when it is in two different situations: moving towards you and moving away from you. When it approaches, the waves of sound get squashed up, giving rise to a higher frequency (high pitch) but when it is receding the waves are stretched out to give a lower frequency (low pitch). The same thing happens to light. When an object is moving away from us - say a distant galaxy - the waves of light that reach us from it get stretched and the frequency of the light goes down. Instead of the frequency of the light we more often talk about its wavelength. You probably remember something about wavelengths from your school physics. You know, ripple tanks, long springs that stretched across the class. What fun! Anyway, the wavelength is the distance between two consecutive wave crests. So a drop in frequency of light is really due to the stretching of the wavelengths." Jim Al-Khalili, As the observer starts moving towards the SOUND source, the wavelength of the sound waves remains unchanged - the increase in frequency that the observer registers is due to an increase in the speed of the sound waves relative to him. You say above: "The same thing happens to light." Does this mean that, as the observer starts moving towards the LIGHT source, the wavelength of the light waves remains unchanged - the increase in frequency that the observer registers is due to an increase in the speed of the light waves relative to him?

THE STATEMENT THAT ANNIHILATES EINSTEINIANA
Zombie education in Einsteiniana's schizophrenic world (Brian Cox
seems to be regarded as the ideal product of zombie education): http://www.youtube.com/watch?v=HY2R2d6AVPM "What is redshift? And what is this Doppler effect? What does this tell us about the universe? Quite a lot actually. Enter the realms of Astrophysics as we look at the evidence for an expanding universe and learn how it all began! Future Astronomers start here! In a few years, you could be the next Brian Cox!" Einsteinians, This is not funny. The motion of the observer CANNOT alter the wavelength and yet the observer measures a frequency shift as he changes his speed. Why? If you were able to explain the problem to children, there would be no next Brian Cox.

THE STATEMENT THAT ANNIHILATES EINSTEINIANA
Moving observer measures VARIABLE speed of light:
http://rockpile.phys.virginia.edu/mod04/mod34.pdf Paul Fendley: "Now let's see what this does to the frequency of the light. We know that even without special relativity, observers moving at different velocities measure different frequencies. (This is the reason the pitch of an ambulance changes as it passes you it doesn't change if you're on the ambulance). This is called the Doppler shift, and for small relative velocity v it is easy to show that the frequency shifts from f to f(1+v/c) (it goes up heading toward you, down away from you). There are relativistic corrections, but these are negligible here." By taking into account the formula: (frequency) = (speed of light)/(wavelength) one concludes that the speed of light (relative to the observer) shifts from c to c+v. Pentcho Valev |

THE STATEMENT THAT ANNIHILATES EINSTEINIANA
Moving observer paradoxes in Einsteiniana's schizophrenic world:
http://www.hep.man.ac.uk/u/roger/PHY.../lecture18.pdf Roger Barlow, Professor of Particle Physics: "Moving Observer. 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 fŒ=(c + v)/ (lambda). (...) Relativistic Doppler Effect. These results depend on the absolute velocities of the source and observer, not just on the relative velocity of the two. That seems odd, but is allowable as sound waves are waves in a medium, and motion relative to the medium may legitimately matter. But for light (or EM radiation in general) there is no medium, and this must be wrong. This needs relativity. (...) If the source is regarded as fixed and the observer is moving, then the observer's clock runs slow. They will measure time intervals as being shorter than they are in the rest frame of the source, and so they will measure frequencies as being higher, again by a gamma factor." Normal physicists clearly see that the motion of the observer CANNOT alter the wavelength of any wave so the only reasonable conclusion is that the speed of the light wave (relative to the observer) varies with the speed of the observer (c'=c+v). Accordingly, for the sake of salary, normal physicists are forced to add some idiotic camouflage - the more idiotic, the better. Paradoxically, deranged Einsteinians do not resort to idiotic camouflage. Silly Einsteinians simply avoid the issue (crimestop) while "the subtlest practitioners of doublethink" convincingly declare that the motion of the observer does alter the wavelength and that's it: 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)."

But then, wavelength is NOT an intrinsic property of a light wave. What does change with the observer's velocity is the RELATIONSHIP between the observer's wavelength-measuring apparatus and the light wave, and this causes differently moving observers to MEASURE different wavelengths for the same light wave. Light is not sound (DUH!). Tom Roberts If you are right, Honest Roberts, then Einsteiniana's education presenting the wavelength as an intrinsic property of the light wave - as "the distance between crests" - is perniciously misleading: 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)." But let us ignore this for the moment and concentrate on the following wisdom of yours: Tom Roberts: "NOTHING that is intrinsic to the light wave "changes". (...) What does change with the observer's velocity is the RELATIONSHIP between the observer's wavelength-measuring apparatus and the light wave, and this causes differently moving observers to MEASURE different wavelengths for the same light wave." Then, Honest Roberts, you should explain the case in which "NOTHING that is intrinsic to the light wave changes", on the one hand, and the observer's velocity does not change either, on the other: http://www.amazon.com/Brief-History-.../dp/0553380168 Stephen Hawking, "A Brief History of Time", Chapter 3: "...we must first understand the Doppler effect. As we have seen, visible light consists of fluctuations, or waves, in the electromagnetic field. The wavelength (or distance from one wave crest to the next) of light is extremely small, ranging from four to seven ten-millionths of a meter. The different wavelengths of light are what the human eye sees as different colors, with the longest wavelengths appearing at the red end of the spectrum and the shortest wavelengths at the blue end. Now imagine a source of light at a constant distance from us, such as a star, emitting waves of light at a constant wavelength. Obviously the wavelength of the waves we receive will be the same as the wavelength at which they are emitted (the gravitational field of the galaxy will not be large enough to have a significant effect). Suppose now that the source starts moving toward us. When the source emits the next wave crest it will be nearer to us, so the distance between wave crests will be smaller than when the star was stationary. This means that the wavelength of the waves we receive is shorter than when the star was stationary. Correspondingly, if the source is moving away from us, the wavelength of the waves we receive will be longer. In the case of light, therefore, means that stars moving away from us will have their spectra shifted toward the red end of the spectrum (red-shifted) and those moving toward us will have their spectra blue-shifted." Does the wavelength AS MEASURED BY THE OBSERVER vary with the velocity of the source and if yes why, Honest Roberts? Pentcho Valev |
