Einstein, Poincaré, Newton
http://www.dailymotion.com/video/xlo...elativite_news
"L'escroc Einstein voleur des travaux de Poincaré sur la Relativité!!" Le fait indiscutable que Einstein plagia Poincaré n'implique pas que la théorie plagiée était correcte. Les textes suivants montrent, sans équivoque, que Poincaré était sur le chemin vers la théorie de l'émission de Newton où la vitesse de la lumière est relative, comme la vitesse de tout corps en mouvement: http://arxiv.org/PS_cache/physics/pd.../0008229v1.pdf "Truly, Lorentz had to change something to his theory. He makes then the very astonishing proposal that the ether wind has a dynamical effect of contraction of all objects along the direction of motion! This contraction reduces the length of the longitudinal arm of Michelson's interferometer in such a way that it exactly compensates the second order effect of Earth motion... (...) This reduction of length is common to all materials and is therefore not measurable by any mechanical device (length standards are reduced in just the same way). In fact, the contraction is indirectly measured by the negative result of Michelson-Morley's experiment. This is a typical case of introducing an ad-hoc explanation in order to save a theory!" http://www.brera.unimi.it/sisfa/atti/1998/giannetto.pdf Henri Poincaré: "...les termes du second ordre auraient dû devenir sensibles, et cependant le résultat [de l'expérience de Michelson- Morley] a encore été négatif, la théorie de Lorentz laissant prévoir un résultat positif. On a alors imaginé une hypothèse supplémentai tous les corps subiraient un raccourcissement dans le sens du mouvement de la Terre... cette étrange propriété semblerait un véritable coup de pouce donné par la nature pour éviter que le mouvement de la Terre puisse être révélé par des phénomènes optiques. Ceci ne saurait me satisfaire et je crois devoir dire ici mon sentiment: je considère comme très problables que les phénomènes optiques ne dépendent que des mouvements relatifs des corpes matériels en presence...et cela non pas aux quantités près de l'ordre du carré ou du cube de l'aberration, mais rigouresement." http://www.timeshighereducation.co.u...ode=404936&c=2 "The French polymath Henri Poincare, charged with producing a keynote address on the state of physics and the problems the discipline faced, warned of the need to root out dangerous hypotheses. In an extended discussion of electrodynamics, and of Hendrik Lorentz's hypothesis of length contraction by bodies in relative motion, Poincare raised the prospect that the ether must be abandoned as an unsupported hypothesis. He discussed the principle of relative motion in his 1900 papers, and named it the principle of relativity in 1904, according to which no mechanical or electromagnetic experiment can discriminate between a state of uniform motion and a state of rest. You'll not find that information in many undergraduate textbooks. Einstein, then aged just 21, was not in Paris (he was finishing his finals), but Poincare's paper was published in the leading German physics journal." Pentcho Valev |
