TRUTH:

"However, if the siren is moving towards the stationary observer, then
the distance between successive wavecrests is reduced by the distance
traveled by the source during one period. This resulting decreased
wavelength..."

In this case Einsteiniana's teachers establish the LIE (which is
always one leap ahead of the truth) in an implicit way: the reader
gets the impression that, even if the observer were moving towards the
stationary wave source, the wavelength would decrease again (and the
speed of the wave relative to the observer would remain CONSTANT, that
is, believers sing "Divine Einstein" and go into convulsions).

Pernicious relativism in Einsteiniana:

As you start moving against waves, wavecrests start hitting you more
frequently, that is, their speed relative to you increases. In
Einsteiniana this trivial (but very dangerous) truth is replaced by a
new truth: wavecrests start hitting you more frequently because the
wavelength somehow depends on your speed and decreases as soon as you
start moving against the waves (accordingly, the wavecrests continue
hitting you with CONSTANT SPEED, that is, believers sing "Divine
Einstein" and go into convulsions):

"Moving observer: A man is standing on the beach, watching the tide.
The waves are washing into the shore and over his feet with a constant
frequency and wavelength. However, if he begins walking out into the
ocean, the waves will begin hitting him more frequently, leading him
to perceive that the wavelength of the waves has decreased. Again,
this phenomenon is due to the fact that the source and the observer
are not the in the same frame of reference. Although the wavelength
appears to have decreased to the man, the wavelength would appear
constant to a jellyfish floating along with the tide."

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)."

Now the top of a tower sends light towards the ground and the
frequency increases again: F'=F(1+V/c^2), where F is the frequency
measured at the top, F' is the frequency measured at the ground and V
is the gravitational potential difference between the top and the
ground. The old Newtonian truth is: wavecrests hit the ground more
frequently because their speed has increased between the top and the
ground: c'=c(1+V/c^2). Einsteinians hate the old Newtonian truth
because it implies that wavecrests hit an accelerated observer with
speed c'=c+v, where v is the speed of the emitter relative to the
observer. Accordingly, two additional truths have replaced the old
Newtonian truth in Einsteiniana:

(1) Wavecrests hit the ground more frequently because clocks at the
top of the tower somehow run faster than clocks at the ground.
Accordingly, wavecrests hit the ground with UNCHANGED SPEED c'=c, that
is, believers sing "Divine Einstein" and go into convulsions.

(2) Wavecrests hit the ground with frequency F'=F(1+V/c^2) but their
speed relative to the ground is greater than in the old Newtonian
truth: the new speed is c'=c(1+2V/c^2). Believers accept this new
truth as well but sing "Divine Einstein" without enthusiasm and do not
go into convulsions.

George Orwell: "Doublethink means the power of holding two
contradictory beliefs in one's mind simultaneously, and accepting both
of them. The Party intellectual knows in which direction his memories
must be altered; he therefore knows that he is playing tricks with
reality; but by the exercise of doublethink he also satisfies himself
that reality is not violated. The process has to be conscious, or it
would not be carried out with sufficient precision, but it also has to
be unconscious, or it would bring with it a feeling of falsity and
hence of guilt. Doublethink lies at the very heart of Ingsoc, since
the essential act of the Party is to use conscious deception while
retaining the firmness of purpose that goes with complete honesty. To
tell deliberate lies while genuinely believing in them, to forget any
fact that has become inconvenient, and then, when it becomes necessary
again, to draw it back from oblivion for just so long as it is needed,
to deny the existence of objective reality and all the while to take
account of the reality which one denies - all this is indispensably
necessary. Even in using the word doublethink it is necessary to
exercise doublethink. For by using the word one admits that one is
tampering with reality; by a fresh act of doublethink one erases this
knowledge ; and so on indefinitely, with the lie always one leap ahead
of the truth. (...) It need hardly be said that the subtlest
practitioners of doublethink are those who invented doublethink and
know that it is a vast system of mental cheating. In our society,
those who have the best knowledge of what is happening are also those
who are furthest from seeing the world as it is. In general, the
greater the understanding, the greater the delusion ; the more
intelligent, the less sane."
