"A doppler effect also occurs when an observer moves towards a source, but here the wavelength does not change, instead it is the effective velocity that changes and leads to an apparent change in the frequency of the SOUND."

The substitution of "LIGHT" for "SOUND" is obviously fatal for special relativity - the speed of the light waves relative to the observer varies with the speed of the observer:

"A doppler effect also occurs when an observer moves towards a source, but here the wavelength does not change, instead it is the effective velocity that changes and leads to an apparent change in the frequency of the LIGHT."

How do Einsteinians deal with the danger? It is universally taught that, for sound waves, the frequency as measured by the moving observer is:

f' = (c+v)/L = c'/L

where c is the speed of the waves relative to the stationary observer, v is the speed with which the observer moves towards the source, c' is the speed of the waves relative to moving observer, L is the invariable wavelength. Einsteinians readily apply the first equation to light waves:

f' = (c+v)/L = ...

but then suddenly stop, as though by instinct:

George Orwell: "Crimestop means the faculty of stopping short, as though by instinct, at the threshold of any dangerous thought. It includes the power of not grasping analogies, of failing to perceive logical errors, of misunderstanding the simplest arguments if they are inimical to Ingsoc, and of being bored or repelled by any train of thought which is capable of leading in a heretical direction. Crimestop, in short, means protective stupidity."

If it were not for crimestop, Einsteinians would have to explicitly reject the analogy with sound waves and declare that light waves obey the following equations:

f' = (c+v)/L = c/L'

where L'=cL/(c+v) is the varying wavelength which varies so as to guarantee both the constancy of the speed of light and the salaries of Einsteinians. However L'=cL/(c+v) is too silly and therefore dangerous. Crimestop is obligatory in such cases:

f' = (c+v)/L = Divine Einstein, yes we all believe in relativity, relativity, relativity.
