Default SANITY AGAINST RELATIVITY

Insane desperate wrestling:

http://www.aip.org/history/einstein/...relativity.htm
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."

The proposition that the speed of light is independent of the speed of the observer is so insane that, even though it is a valid consequence of the Lorentz transform, the inventors of the Lorentz transform still did not adopt it:

http://www.persee.fr/web/revues/home..._num_55_1_2143
Les écrits épistémologiques de Poincaré, obstacles à la diffusion de la relativité?, Vincent Borella, p. 74: "Pour Einstein le postulat de la constance de la vitesse de la lumière par rapport à n'importe quel référentiel dans lequel elle est mesurée (ce qui est une expression du principe de relativité) est suffisant, alors qu'en fait, pour Poincaré, la vitesse de la lumière ne peut être constante que relativement au milieu dans lequel elle se propage, à savoir l'éther supposé immobile."

http://www.jstor.org/stable/3653092
The Mystery of the Einstein-Poincaré Connection, Olivier Darrigol: "It is clear from the context that Poincaré meant here to apply the postulate [of constancy of the speed of light] only in an ether-bound frame, in which case he could indeed state that it had been "accepted by everybody." In 1900 and in later writings he defined the apparent time of a moving observer in such a way that the velocity of light measured by this observer would be the same as if he were at rest (with respect to the ether). This does not mean, however, that he meant the postulate to apply in any inertial frame. From his point of view, the true velocity of light in a moving frame was not a constant but was given by the Galilean law of addition of velocities."

For sane people, the Doppler effect (moving observer) unequivocally shows that the speed of light does vary with the speed of the observer:

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."

That is, if the frequency measured by the stationary observer is f=c/L (L is the wavelength), the frequency measured by an observer moving towards the light source with speed v is:

f' = f(1+v/c) = (c/L)(1+v/c) = (c+v)/L = c'/L

where c'=c+v is the speed of the light waves relative to the moving observer. Clearly special relativity is violated.

Needless to say, the formula c'=c+v immediately switches Einsteinians' minds to crimestop regime:

http://ebooks.adelaide.edu.au/o/orwe...hapter2.9.html
"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."

Default SANITY AGAINST RELATIVITY

Classical insanity in Divine Albert's world: "mutual time dilation":

http://www.einstein-online.info/dict.../time-dilation
"Time dilation can be mutual: When two inertial observers speed past each other, each will find that the other's clocks go slower."

http://www.amazon.com/Relativity-Its.../dp/0486406768
Relativity and Its Roots, Banesh Hoffmann, p. 105: "In one case your clock is checked against two of mine, while in the other case my clock is checked against two of yours, and this permits us each to find without contradiction that the other's clocks go more slowly than his own."

There is nothing in Banesh Hoffmann's text above that justifies the words "without contradiction". "Without contradiction" could be justified if Einsteinians had devised and discussed at least one scenario where EITHER observer's clock is checked against two of the other observer's clocks (at some distance from one another). Instead, discussions in Divine Albert's world are restricted to the misleading twin paradox scenario where the travelling twin is implicitly deprived of the setup "two clocks at some distance from one another against which the sedentary twin's clock could be checked" and so there is no way to demonstrate the slowness of the sedentary twin's clock. Only the slowness of the travelling twin's clock can be demonstrated, Divine Einstein, yes we all believe in relativity, relativity, relativity.

The following scenario allows EITHER observer's clock to be checked against two of the other observer's clocks. Two long inertial systems each carrying synchronous clocks pass one another:

..........Inertial system A moving to the right..........
..........Inertial system B moving to the left..........

The systems are so designed that, the moment they stop moving relative to one another, all clocks on both systems stop ticking. In this final static configuration clock A2 faces clock B1 and clock A1 faces clock B2:

..........A2..........A1..........
..........B1..........B2..........

Before reaching clock A2, clock B1 passed clock A1 and the difference in their readings, (A1then - B1then), was then registered. *Now*, in the final static configuration, clock B1 faces clock A2 and the difference in their readings is (A2now - B1now). Clearly clock B1 has been checked against two of Inertial system A's clocks so, according to special relativity, the following inequality holds:

(A2now - B1now) (A1then - B1then) /1/

Before reaching clock B2, clock A1 passed clock B1 and the difference in their readings, (B1then - A1then), was then registered. *Now*, in the final static configuration, clock A1 faces clock B2 and the difference in their readings is (B2now - A1now). Clearly clock A1 has been checked against two of Inertial system B's clocks so, according to special relativity, the following inequality holds:

(B2now - A1now) (B1then - A1then)

This inequality easily becomes:

(A1then - B1then) (A1now - B2now)

Since clocks on Inertial system A were synchronous and stopped ticking simultaneously, A1now = A2now. For the same reason B2now = B1now. So the last inequality becomes:

(A1then - B1then) (A2now - B1now) /2/

Inequalities /1/ and /2/ are contradictory and both are consequences of Einstein's 1905 light postulate. Reductio ad absurdum par excellence. The light postulate is false. Einstein should not have "introduced as his second postulate something that was more or less obvious when thought of in terms of waves in an ether":

http://books.google.com/books?id=JokgnS1JtmMC
"Relativity and Its Roots" By Banesh Hoffmann, p.92: "There are various remarks to be made about this second principle. For instance, if it is so obvious, how could it turn out to be part of a revolution - especially when the first principle is also a natural one? 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. If it was so obvious, though, why did he need to state it as a principle? Because, having taken from the idea of light waves in the ether the one aspect that he needed, he declared early in his paper, to quote his own words, that "the introduction of a 'luminiferous ether' will prove to be superfluous."
