Default Albert Einstein: Genius of ... Brainwashing

Albert Einstein, On the Principle of Relativity: "This statement is essentially what physicists call the "principle of relativity." One can phrase this principle in a general fashion as: "The laws of nature perceived by an observer are independent of his state of motion." This statement sounds harmless and self-evident. It would not have excited anybody but for the fact that the laws of the propagation of light, which, having emerged from the recent development in electrodynamics, seem to be incompatible with this principle. The phenomena of the optics of moving bodies lead to the interpretation that light in empty space always propagates with the same velocity, irrespective of the state of motion of the light source. Yet this result seems to be in contradiction with the aforementioned 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. This is where the theory of relativity comes in. This theory shows that the law of constancy of light propagation in vacuum can be satisfied simultaneously for two observers, in relative motion to each other, such that the same beam of light shows the same velocity to both of them." http://einsteinpapers.press.princeton.edu/vol6-trans/15

Einstein explains that two magnificent truths - the principle of relativity and "the law of constancy of light propagation in vacuum" - are in apparent contradiction but the theory of relativity comes in and reconciles them. But what exactly is "the law of constancy of light propagation in vacuum"? Below Banesh Hoffmann explains that this "law" is actually a tenet of the ether theory, initially (before the introduction of "contracting lengths, local time, or Lorentz transformations") incompatible with the null result of the Michelson-Morley experiment:

Banesh Hoffmann, Relativity and Its Roots, p.92: "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." https://www.amazon.com/Relativity-It.../dp/0486406768

Default Albert Einstein: Genius of ... Brainwashing

Richard Feynman mercilessly brainwashing his students/readers:

Richard Feynman: "Now if all moving clocks run slower, if no way of measuring time gives anything but a slower rate, we shall just have to say, in a certain sense, that time itself appears to be slower in a space ship. All the phenomena there - the man's pulse rate, his thought processes, the time he takes to light a cigar, how long it takes to grow up and get old - all these things must be slowed down in the same proportion, because he cannot tell he is moving." http://www.feynmanlectures.caltech.edu/I_15.html

Is it true that "no way of measuring time gives anything but a slower rate"? Of course not - according to special relativity, measurements performed by the traveler himself give a FASTER rate:

David Morin, Introduction to Classical Mechanics With Problems and Solutions, Chapter 11, p. 14: "Twin A stays on the earth, while twin B flies quickly to a distant star and back. [...] For the entire outward and return parts of the trip, B does observe A's clock running slow..." http://www.people.fas.harvard.edu/~djmorin/chap11.pdf

"The situation is that a man sets off in a rocket travelling at high speed away from Earth, whilst his twin brother stays on Earth. [...] ...the twin in the spaceship considers himself to be the stationary twin, and therefore as he looks back towards Earth he sees his brother ageing more slowly than himself." http://topquark.hubpages.com/hub/Twin-Paradox

Who taught Richard Feynman to brainwash so efficiently? His teacher Albert Einstein of course, the genius of brainwashing. This particular lie ("moving clocks run slower") was devised in 1905:

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/

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 but this Section does not contain any results explaining why the (inertial) clock at the center of the rotating disc should run faster than the (non-inertial) clock on the edge of the disc. Rather, the results in Section XII are all based on the Lorentz transformation which predicts SYMMETRICAL time dilation for two INERTIAL clocks: either inertial clock (more precisely, the observer in this clock's system) sees the other inertial clock running SLOW by a factor of 1/gamma = sqrt(1-(v/c)^2).

Max Tegmark: "We all believe in relativity, relativity, relativity. Yes we all believe in relativity, relativity, relativity. Everything is relative, even simultaneity, and soon Einstein's become a de facto physics deity. 'cos we all believe in relativity, relativity, relativity. We all believe in relativity, relativity, relativity. Yes we all believe in relativity, relativity, relativity." https://www.youtube.com/watch?v=5PkLLXhONvQ

Einstein was a perfect brainwasher indeed. Here he informs the gullible world that Newton's emission theory of light is great, will play an important role in the future, and represents no threat to relativity. The two theories share "the unusual property that light carries inertial mass from the emitting to the absorbing object":

Albert Einstein 1909: "A large body of facts shows undeniably that light has certain fundamental properties that are better explained by Newton's emission theory of light than by the oscillation theory. For this reason, I believe that the next phase in the development of theoretical physics will bring us a theory of light that can be considered a fusion of the oscillation and emission theories. The purpose of the following remarks is to justify this belief and to show that a profound change in our views on the composition and essence of light is imperative. [...] Then the electromagnetic fields that make up light no longer appear as a state of a hypothetical medium, but rather as independent entities that the light source gives off, just as in Newton's emission theory of light. [...] Relativity theory has changed our views on light. Light is conceived not as a manifestation of the state of some hypothetical medium, but rather as an independent entity like matter. Moreover, this theory shares with the corpuscular theory of light the unusual property that light carries inertial mass from the emitting to the absorbing object." https://en.wikisource.org/wiki/Trans...e_of_Radiation

John Norton presents Albert Einstein as an extremely talented fraudster. The story Einstein fabricated in 1946 is a masterpiece not only of science but also of culture in our post-truth civilization:

John Norton: "Behind Einstein's Chasing a Light Beam Thought Experiment. These cartoonish impersonations of Einstein's thought experiment are possible because Einstein's account of the thought experiment is brief, cryptic, and puzzling. First, the events recounted happened in late 1895 or early 1896.. Yet Einstein mentions Maxwell's equations, the key equations of nineteenth-century electrodynamics. He did not learn them until his university studies around 1898. Einstein's first report of the thought experiment in his own writings comes in 1946. The thought experiment does not appear in the 1905 special relativity paper, in any later writings prior to 1946, or in his correspondence. Second, unlike the luminous clarity of Einstein's other thought experiments, it is not at all clear how this thought experiment works. In the dominant theories of the late nineteenth century, light propagates as a wave in a medium, the luminiferous ether. It was an entirely uncontroversial result in this theory that, in a frame of reference that moved with the light, the wave would be static. There is no reason for us to be puzzled. We do not see frozen light since we are not moving at the speed of light through the ether."
