DOPPLER HORROR IN EINSTEINIANA

When the observer starts moving relative to the light source, both the frequency and the speed of the waves relative to him obviously change... No! The frequency does change but the speed... Help! Help! Divine Einstein! Yes we all believe in relativity, relativity, relativity! The speed cannot change! Absurd! Impossible! Divine Albert has said the speed never changes:

Dr Ricardo Eusebi: "f'=f(1+v/c). Light frequency is relative to the observer. The velocity is not though. The velocity is the same in all the reference frames."

Since the frequency changes and the speed of the waves relative to the observer should not change, Divine Einstein, yes we all believe in relativity, relativity, relativity, then the motion of the observer must somehow change the wavelength, even if the idea sounds too idiotic. The only problem is that some clever student may ask: "Well, the motion of the observer does change the wavelength of light waves but does not change the wavelength of sound waves - why?" To avoid this question, the most faithful Einsteinians teach that the motion of the observer changes the wavelength of all waves so that the speed of the waves as measured by the observer can gloriously remain constant, Divine Einstein, yes we all believe in relativity, relativity, relativity:

"The observer moves closer to the source. The wave received has a shorter wavelength (higher frequency) than that emitted by the source. The observer moves away from the source. The wave received has a longer wavelength (lower frequency) than that emitted by the source."

John Stachel: "But here he ran into the most blatant-seeming contradiction, which I mentioned earlier when first discussing the two principles. As noted then, the Maxwell-Lorentz equations imply that there exists (at least) one inertial frame in which the speed of light is a constant regardless of the motion of the light source. Einstein's version of the relativity principle (minus the ether) requires that, if this is true for one inertial frame, it must be true for all inertial frames. But this seems to be nonsense. How can it happen that the speed of light relative to an observer cannot be increased or decreased if that observer moves towards or away from a light beam? Einstein states that he wrestled with this problem over a lengthy period of time, to the point of despair. We have no details of this struggle, unfortunately. Finally, after a day spent wrestling once more with the problem in the company of his friend and patent office colleague Michele Besso, the only person thanked in the 1905 SRT paper, there came a moment of crucial insight. In all of his struggles with the emission theory as well as with Lorentz's theory, he had been assuming that the ordinary Newtonian law of addition of velocities was unproblematic. It is this law of addition of velocities that allows one to "prove" that, if the velocity of light is constant with respect to one inertial frame, it cannot be constant with respect to any other inertial frame moving with respect to the first. It suddenly dawned on Einstein that this "obvious" law was based on certain assumptions about the nature of time..."

Time did obey Divine Albert's orders - it started to flow differently for the moving observer so that the speed of light the observer measured could gloriously remain constant. Unfortunately Divine Albert forgot to tell the wavelength of the light wave to vary with the speed of the observer and neutralize the frequency shift. The danger is obvious - people may look at the formula:

(frequency) = (speed of light)/(wavelength)

and come to the conclusion: "The frequency shifts so if the motion of the observer cannot alter the wavelength, then the speed of light as measured by the observer shifts as well. Divine Albert is wrong, no we don't believe in relativity, relativity, relativity anymore".
