• Einstein and the Too Gullible World

    Einstein informs the gullible world that the inertial clock at the center of the rotating disk runs faster than the non-inertial clock on the edge of the disk, and that this is a consequence of the Lorentz transformation:

    Albert Einstein: "An observer who is sitting eccentrically on the disc K' is sensible of a force which acts outwards in a radial direction...The observer performs experiments on his circular disc with clocks and measuring-rods. In doing so, it is his
    intention to arrive at exact definitions for the signification of time- and space-data with reference to the circular disc K', these definitions being based on his observations. What will be his experience in this enterprise? To start with, he places one
    of two identically constructed clocks at the centre of the circular disc, and the other on the edge of the disc, so that they are at rest relative to it. We now ask ourselves whether both clocks go at the same rate from the standpoint of the non-rotating
    Galileian reference-body K. As judged from this body, the clock at the centre of the disc has no velocity, whereas the clock at the edge of the disc is in motion relative to K in consequence of the rotation. According to a result obtained in Section XII,
    it follows that the latter clock goes at a rate permanently slower than that of the clock at the centre of the circular disc, i.e. as observed from K." http://www.bartleby.com/173/23.html

    Einstein refers to Section XII

    https://www.bartleby.com/173/12.html

    but this Section does not contain any results explaining why the (inertial) clock at the center of the rotating disk should run FASTER than the (non-inertial) clock on the edge of the disk. Rather, the results in Section XII are all based on the Lorentz
    transformation which predicts SYMMETRIC time dilation for two inertial clocks: either clock runs slower than the other by a factor of 1/gamma = sqrt(1-(v/c)^2), as judged from the other clock's system.

    Einstein's 1905 postulates, true or false, entail the following conclusion:

    (A) If two clocks are in relative motion, either clock is slower than the other as judged from the other clock's system.

    The conclusion is validly deducible from the postulates but is obviously preposterous. It implies that, if two clocks are initially stationary and synchronized, then move relative to one another and finally meet, either clock lags behind the other as
    judged from the other clock's system. So if Einstein had explicitly stated the validly deducible conclusion (A) in 1905, Max Planck would not have found courage to publish his paper.

    Instead of the valid deduction (A), Einstein advanced the following non sequitur (not following from Einstein's 1905 postulates):

    (B) If two clocks are in relative motion, the moving one is slow and the stationary one is fast.

    Here is the fraudulent text:

    Albert Einstein, On the Electrodynamics of Moving Bodies, 1905: "From this there ensues the following peculiar consequence. If at the points A and B of K there are stationary clocks which, viewed in the stationary system, are synchronous; and if the
    clock at A is moved with the velocity v along the line AB to B, then on its arrival at B the two clocks no longer synchronize, but the clock moved from A to B lags behind the other which has remained at B by tv^2/2c^2 (up to magnitudes of fourth and
    higher order), t being the time occupied in the journey from A to B." http://www.fourmilab.ch/etexts/einstein/specrel/www/

    It is easy to see that the valid deduction (A) doesn't, but the non sequitur (B) does predict TIME TRAVEL INTO THE FUTURE - the miracle (more precisely, idiocy) that converted Einstein into a deity:

    "The paradigm of the special relativistic upheaval of the usual concept of time is the twin paradox. Let us emphasize that this striking example of time dilation proves that time travel (towards the future) is possible. As a gedanken experiment (if we
    neglect practicalities such as the technology needed for reaching velocities comparable to the velocity of light, the cost of the fuel and the capacity of the traveller to sustain high accelerations), it shows that a sentient being can jump, "within a
    minute" (of his experienced time) arbitrarily far in the future, say sixty million years ahead, and see, and be part of, what (will) happen then on Earth. This is a clear way of realizing that the future "already exists" (as we can experience it "in a
    minute")." http://www.bourbaphy.fr/damourtemps.pdf

    Here Einstein clearly states that his 1905 two postulates, the principle of relativity and the principle of constancy of the speed of light, are logically independent from one another:

    Albert Einstein: "...it is impossible to base a theory of the transformation laws of space and time on the principle of relativity alone. As we know, this is connected with the relativity of the concepts of "simultaneity" and "shape of moving bodies." To
    fill this gap, I introduced the principle of the constancy of the velocity of light, which I borrowed from H. A. Lorentz's theory of the stationary luminiferous ether." https://en.wikipedia.org/wiki/Lorentz_ether_theory

    The gullible world, however, has been brainwashed into believing that the second postulate, the constancy of the speed of light, is a logical consequence of the first, the principle of relativity:

    Albert Einstein: "If a ray of light be sent along the embankment, we see from the above that the tip of the ray will be transmitted with the velocity c relative to the embankment. Now let us suppose that our railway carriage is again travelling along the
    railway lines with the velocity v, and that its direction is the same as that of the ray of light, but its velocity of course much less. Let us inquire about the velocity of propagation of the ray of light relative to the carriage. It is obvious that we
    can here apply the consideration of the previous section, since the ray of light plays the part of the man walking along relatively to the carriage. The velocity W of the man relative to the embankment is here replaced by the velocity of light relative
    to the embankment. w is the required velocity of light with respect to the carriage, and we have w = c - v. The velocity of propagation of a ray of light relative to the carriage thus comes out smaller than c. But this result comes into conflict with the
    principle of relativity set forth in Section 5." http://www.bartleby.com/173/7.html

    Albert Einstein, On the Principle of Relativity: "After all, when a beam of light travels with a stated velocity relative to one observer, then - so it seems - a second observer who is himself traveling in the direction of the propagation of the light
    beam should find the light beam propagating at a lesser velocity than the first observer does. If this were really true, then the law of light propagation in vacuum would not be the same for two observers who are in relative, uniform motion to each other
    - in contradiction to the principle of relativity stated above." https://einsteinpapers.press.princeton.edu/vol6-trans/16

    Dave Slaven: "Einstein's first postulate seems perfectly reasonable. And his second postulate follows very reasonably from his first. How strange that the consequences will seem so unreasonable." http://webs.morningside.edu/slaven/Physics/relativity/
    relativity3.html

    Professor Raymond Flood: "A consequence of Einstein's principle of relativity is that the speed of light in vacuum has the same value in two uniformly moving frames of reference." https://youtu.be/IjRSYv7u3T4?t=304

    Chad Orzel: "The core idea of Einstein's theory of relativity can fit on a bumper sticker: The Laws Of Physics Do Not Depend On How You're Moving. Absolutely everything else follows from the simple realization that physics must appear exactly the same to
    person in motion as to a person at rest - the constant speed of light, the slowing of time for moving observers, E=mc2, black holes, even the expanding universe (I've written a whole book about this, explained through imaginary conversations with my dog).
    " http://www.forbes.com/sites/chadorzel/2015/05/29/four-reasons-to-not-fear-physics/

    Michael Fowler: "Therefore, demanding that the laws of physics are the same in all inertial frames implies that the speed of any light wave, measured in any inertial frame, must be 186,300 miles per second. This then is the entire content of the Theory
    of Special Relativity: the Laws of Physics are the same in any inertial frame, and, in particular, any measurement of the speed of light in any inertial frame will always give 186,300 miles per second." http://galileo.phys.virginia.edu/classes/109/
    lectures/spec_rel.html

    Leonard Susskind: "The principle of relativity is that the laws of physics are the same in every reference frame. That principle existed before Einstein. Einstein added one law of physics - the law of physics is that the speed of light is the speed of
    light, c. If you combine the two things together - that the laws of physics are the same in every reference frame, and that it's a law of physics that light moves with certain velocity, you come to the conclusion that light must move with the same
    velocity in every reference frame. Why? Because the principle of relativity says that the laws of physics are the same in every reference frame, and Einstein announced that it is a law of physics that light moves with a certain velocity." https://youtu.
