In this way he hoped to have a word that would mean the same to everyone regardless of their language, and, as Cooper [2] remarked, he succeeded in this way in finding a word that meant the same to everyone: NOTHING. From the beginning it proved a very difficult concept for other thermodynamicists, even including such accomplished mathematicians as Kelvin and Maxwell; Kelvin, indeed, despite his own major contributions to the subject, never appreciated the idea of entropy [3]. The difficulties that Clausius created have continued to the present day, with the result that a fundamental idea that is absolutely necessary for understanding the theory of chemical equilibria continues to give trouble, not only to students but also to scientists who need the concept for their work." http://www.rsc.org/pdf/uchemed/papers/2002/p2_carson.pdf "For many students, the study of thermodynamics presents problems; it is seen as consisting almost entirely of equations which are not understood and which have to be learned by rote in order to do calculations and to pass examinations." http://articles.courant.com/2009-03-26/news/thorson0326.art_1_science-education-theory-of-general-relativity-arthur-eddington "Albert Einstein strengthened science through his contributions, but he may have inadvertently crippled science education through his example. This notion is supported by an editorial, "Redefining Science Education," published in January by Bruce Alberts, editor in chief of the journal Science. His main concern is that "many college-educated adults in the United States," including teachers, "fail to understand that science is a way of knowing completely different from mysticism, tradition and faith." Science is based on "evidence that can be logically and independently verified," rather than on personal authority. Most of the public accepted Einstein's 1915 theory of general relativity based on his authority, rather than on the evidence presented. Few teachers have worked their way through the logic, and fewer still have worked through the equations dominated by tensors and scalars. When teachers explain relativity to their students, they do so as if it were a revealed truth, in this case channeled to Earth by a super-smart scientist. Most scientists accepted his theory only after his predictions were confirmed by measurements obtained by British scientist Arthur Eddington during a solar eclipse on May 29, 1919. During those few minutes, the sun's rays were bent by an angle of 1.7 arc-seconds, rather than 0.83 arc-seconds, supporting Einstein's predictions based on the warp and woof of space-time, rather than those based on Newton's version of gravity." http://www.newscientist.com/article/mg16321935.300-ode-to-albert.html New Scientist: Ode to Albert "Enter another piece of luck for Einstein. We now know that the light- bending effect was actually too small for Eddington to have discerned at that time. Had Eddington not been so receptive to Einstein's theory, he might not have reached such strong conclusions so soon, and the world would have had to wait for more accurate eclipse measurements to confirm general relativity." http://www.amazon.com/Brief-History-Time-Stephen-Hawking/dp/0553380168 Stephen Hawking: "Einsteins prediction of light deflection could not be tested immediately in 1915, because the First World War was in progress, and it was not until 1919 that a British expedition, observing an eclipse from West Africa, showed that light was indeed deflected by the sun, just as predicted by the theory. This proof of a German theory by British scientists was hailed as a great act of reconciliation between the two countries after the war. It is ionic, therefore, that later examination of the photographs taken on that expedition showed the errors were as great as the effect they were trying to measure. Their measurement had been sheer luck, or a case of knowing the result they wanted to get, not an uncommon occurrence in science." http://discovermagazine.com/2008/mar/20-things-you-didn.t-know-about-relativity "The eclipse experiment finally happened in 1919 (youre looking at it on this very page). Eminent British physicist Arthur Eddington declared general relativity a success, catapulting Einstein into fame and onto coffee mugs. In retrospect, it seems that Eddington fudged the results, throwing out photos that showed the wrong outcome. No wonder nobody noticed: At the time of Einsteins death in 1955, scientists still had almost no evidence of general relativity in action." http://www.renewamerica.us/columns/hutchison/080616 "Like bronze idols that are hollow inside, Einstein built a cluster of "Potemkin villages," which are false fronts with nothing behind them. Grigori Potemkin (17391791) was a general-field marshal, Russian statesman, and favorite of Empress Catherine the Great. He is alleged to have built facades of non-existent villages along desolate stretches of the Dnieper River to impress Catherine as she sailed to the Crimea in 1787. Actors posing as happy peasants stood in front of these pretty stage sets and waved to the pleased Empress. This incident reminds me of the story of Eleanor Roosevelt's Moscow tour guide who showed her the living quarters of communist party bosses and claimed that these were the apartments of the average Russian worker. The incredibly gullible first lady was delighted. Like Catherine, the sentimental Eleanor was prone to wishful thinking and was easily deceived. What has all this to do with Einstein? The science establishment has a powerful romantic desire to believe in Einstein. Therefore, they are not only fooled by Einstein's tricks, they are prepared to defend his Potemkin villages."

All of these theories appear correct within certain ranges but have conflicts at their boundaries. Scientists struggled thru the last half of the twentieth century to find a "Unified Field Theory" that could join these theories. The results of this effort could best be described as mathematical masturbation." http://www.edge.org/q2008/q08_5.html John Baez (Einsteiniana's most famous teacher): "On the one hand we have the Standard Model, which tries to explain all the forces except gravity, and takes quantum mechanics into account. On the other hand we have General Relativity, which tries to explain gravity, and does not take quantum mechanics into account. Both theories seem to be more or less on the right track but until we somehow fit them together, or completely discard one or both, our picture of the world will be deeply schizophrenic. (...) I realized I didn't have enough confidence in either theory to engage in these heated debates. I also realized that there were other questions to work on: questions where I could actually tell when I was on the right track, questions where researchers cooperate more and fight less. So, I eventually decided to quit working on quantum gravity." http://canadafreepress.com/index.php/article/23682 "In 1929, when spectral analysis revealed a 'red shift' in distant galaxies, astronomer Edwin Hubble speculated that this might be due to acceleration away from Earth and a possible expanding universe. Before he could reflect on other possible explanations, a radio interview stumbled onto the phrase "Big Bang" and a run-away train left the station. Dr Hubble was uncomfortable with both the concept and the catchy nick-name, but he had a 'conflict of interest' on this issue. In a Times magazine interview, on Dec 14, 1936, titled "Science: Shift on Shift", Dr. Hubble made his opposition clear. One reason that he was not more forceful was because he was begging the government for funding of the Mount Palomar telescope." http://www.time.com/time/magazine/article/0,9171,757145,00.html Monday, Dec. 14, 1936: "Other causes for the redshift were suggested, such as cosmic dust or a change in the nature of light over great stretches of space. Two years ago Dr. Hubble admitted that the expanding universe might be an illusion, but implied that this was a cautious and colorless view. Last week it was apparent that he had shifted his position even further away from a literal interpretation of the redshift, that he now regards the expanding universe as more improbable than a non-expanding one." http://www.nytimes.com/2010/01/26/science/26essay.html "The worrying continued.

L'année suivante, Walter Adams mesurerait exactement ces 0.007%. Il s'avère aujourd'hui que ces mesures , qui constituèrent pendant quarante ans une "preuves" de la relativité, étaient largement "arrangée" tant était grand le désir de vérifier la théorie d'Enstein.

Einstein et Besso aboutissent finalement sur un nombre aberrant et s'aperçoivent qu'en fait le résultat est cent fois trop grand à cause d'une erreur dans la masse du soleil...

Certes, sur ces 574 s, 531 s'expliquaient par les perturbations gravitationnels dues aux autres planètes. Mais restait 43 s, le fameux effet "périhélique " inexpliqué par les lois de Newton. Le calcul relativiste d'Einstein donna 42,98 s ! L'accord et si parfait qu'il ne laisse la place à aucune discussion. Or depuis 1966, le soleil est soupçonné ne pas être rigoureusement sphérique mais légèrement aplati à l'équateur. Une très légère dissymétries qui suffirait à faire avancer le périhélie de quelques secondes d'arc.

A popular but pernicious principle in deductive science preached by Karl Popper: Karl Popper: "Only observation and experiment may decide upon the acceptance or rejection of scientific statements, including laws and theories." In 1905 Einstein advances his false light postulate. Then in 1911 he partially replaces it with the true antithesis given by Newton's emission theory of light; so, from 1911 on, his theory "correctly" predicts the gravitational redshift factor: http://www.blazelabs.com/f-g-gcont.asp "So, faced with this evidence most readers must be wondering why we learn about the importance of the constancy of speed of light. Did Einstein miss this? Sometimes I find out that what's written in our textbooks is just a biased version taken from the original work, so after searching within the original text of the theory of GR by Einstein, I found this quote: "In the second place our result shows that, according to the general theory of relativity, the law of the constancy of the velocity of light in vacuo, which constitutes one of the two fundamental assumptions in the special theory of relativity and to which we have already frequently referred, cannot claim any unlimited validity. A curvature of rays of light can only take place when the velocity of propagation of light varies with position. Now we might think that as a consequence of this, the special theory of relativity and with it the whole theory of relativity would be laid in the dust. But in reality this is not the case. We can only conclude that the special theory of relativity cannot claim an unlimited domain of validity ; its results hold only so long as we are able to disregard the influences of gravitational fields on the phenomena (e.g. of light)." - Albert Einstein (1879-1955) - The General Theory of Relativity: Chapter 22 - A Few Inferences from the General Principle of Relativity-. Today we find that since the Special Theory of Relativity unfortunately became part of the so called mainstream science, it is considered a sacrilege to even suggest that the speed of light be anything other than a constant. This is somewhat surprising since even Einstein himself suggested in a paper "On the Influence of Gravitation on the Propagation of Light," Annalen der Physik, 35, 1911, that the speed of light might vary with the gravitational potential. Indeed, the variation of the speed of light in a vacuum or space is explicitly shown in Einstein's calculation for the angle at which light should bend upon the influence of gravity. One can find his calculation in his paper. The result is c'=c(1+V/c^2) where V is the gravitational potential relative to the point where the measurement is taken. 1+V/c^2 is also known as the GRAVITATIONAL REDSHIFT FACTOR." Finally, in 1960, Pound and Rebka experimentally confirm the prediction. Popper's pernicious principle does not enjoin rejection of any part of the theory although two incompatible statements (Einstein's 1905 false light postulate and the true antithesis given by Newton's emission theory of light) coexist in it. If it were not for Popper's pernicious principle, Einstein's 1905 false light postulate would easily be rejected through REDUCTIO AD ABSURDUM: It follows from Einstein's 1905 false light postulate that an infinitely long object can be trapped inside an infinitely short container. So Einsteinians can gloriously obtain any decrease in the object's volume: http://math.ucr.edu/home/baez/physics/Relativity/SR/barn_pole.html "These are the props. You own a barn, 40m long, with automatic doors at either end, that can be opened and closed simultaneously by a switch. You also have a pole, 80m long, which of course won't fit in the barn. Now someone takes the pole and tries to run (at nearly the speed of light) through the barn with the pole horizontal. Special Relativity (SR) says that a moving object is contracted in the direction of motion: this is called the Lorentz Contraction. So, if the pole is set in motion lengthwise, then it will contract in the reference frame of a stationary observer.....So, as the pole passes through the barn, there is an instant when it is completely within the barn. At that instant, you close both doors simultaneously, with your switch. Of course, you open them again pretty quickly, but at least momentarily you had the contracted pole shut up in your barn. The runner emerges from the far door unscathed.....If the doors are kept shut the rod will obviously smash into the barn door at one end. If the door withstands this the leading end of the rod will come to rest in the frame of reference of the stationary observer. There can be no such thing as a rigid rod in relativity so the trailing end will not stop immediately and the rod will be compressed beyond the amount it was Lorentz contracted. If it does not explode under the strain and it is sufficiently elastic it will come to rest and start to spring back to its natural shape but since it is too big for the barn the other end is now going to crash into the back door and the rod will be trapped in a compressed state inside the barn." It follows from Einstein's 1905 false light postulate that an Einsteinian travelling with the rivet sees the bug squashed. The bug sees itself alive and kicking: http://hyperphysics.phy-astr.gsu.edu/Hbase/Relativ/bugrivet.html "The bug-rivet paradox is a variation on the twin paradox and is similar to the pole-barn paradox.....The end of the rivet hits the bottom of the hole before the head of the rivet hits the wall. So it looks like the bug is squashed.....All this is nonsense from the bug's point of view. The rivet head hits the wall when the rivet end is just 0.35 cm down in the hole! The rivet doesn't get close to the bug....The paradox is not resolved." Pentcho Valev pvalev(a)yahoo.com |
