Front wrapper loose but fully intact. "Chilpp 202" and "Recdese 160" written in hand to top of front wrapper. A very fine and clean copy. Pp. 334-351. � First edition in the scarce author's presentation offprint issue of this important paper which contains Einstein's theories on wave-particle duality and German physicist Rupp's work on the same subject seemingly to corroborating Einstein's theories. Rupp's experimental results later turned out to have been falsifications and today he is mainly known as the protagonist in one of the biggest scandals in physics in the 20th century.<br><br>Rupp published a number of papers on the interference properties of light emitted by canal ray sources. These articles particularly the present that came into being in close collaboration with Albert Einstein attracted quite a lot of attention as they probed the wave versus particle nature of light. They also significantly propelled Rupp's career even though they were considered highly controversial to begin with.<br><br>In April 1926 Albert Einstein proposed to Emil Rupp to carry out two experiments that were to prove the wave nature of light versus the particle nature of light: the so-called 'Wire Grid Experiment' and the 'Rotated Mirror Experiment' experiments that Einstein had worked on theoretically and now would like to gain confirmation of through experiments. <br>Rupp at the time regarded as one of the most important and most competent experimental physicists gladly took up the challenge. Rupp's observations - though highly controversial - confirmed Einstein's theory. Due to the surprising outcome of the experiments Einstein was interested in exactly how it they were conducted as Rupp's initial descriptions did not convince him that the results were feasible.<br><br>"Rupp stood by his observations and suggested yet other circumstances that might explain them. Did Einstein now realize that there was something rather dubious about Rupp's work He had seen him change his data repeatedly-and each time in better accordance with his own criticism and on one occasion in no less than two days. He had had to accept that Rupp claimed to earlier have "unknowingly" or "unconsciously" rotated a mirror and he will likely have seen that Rupp's work was highly controversial amongst experimentalists leading to very public criticism in Die Naturwissenschaften. He himself was now also convinced that in fact Rupp's results were incomprehensible. So did Einstein choose to suspend the publication of Rupp's piece so that an additional round of checks and balances could take place <br>The answer is no: Rupp's paper was presented by Einstein to the Prussian Academy in a session on 21 October 1926 and it appeared in print in the Academy's proceedings in November of 1926-the articles by Einstein and Rupp came out back to back and reprints circulated with both papers bound together with a joint cover page that displayed both titles. Einstein referred in his article to Rupp's claims and he had even written the abstract of Rupp's paper" Dongen: "Emil Rupp Albert Einstein and the Canal Ray Experiments on Wave-Particle".<br><br>The first clear indication that Rupp's work was impossible to recreate came in 1930 in a paper published by Staub - nothing was wrong with Einstein's theory but Rupp's work was simply impossible: "Rupp immediately set out to respond to Straub's publication. On 12 July 1930 he sent a first draft to Einstein to whom he also announced his intention of redoing his canal ray experiments-Straub was dismissed as a clumsy graduate student with a lousy apparatus. Einstein suggested inviting Straub once Rupp had his experiment up and running again but cautioned him not to engage the polemic in too sharp a tone". Rupp managed to convince the physics society and continued to publish the new few years. In 1934 various different physicians pointed out that Rupp's work was impossible to recreate and in 1935 the final blow to Rupp's career came about when the German Physical Society's decided not to allow any citations of Rupp's work. This seems to have had very severe consequences as today it is almost impossible to find any quotations - or even mentioning of Rupp in general let alone his fraud - in any historical studies of either quantum theory or of Einstein.<br><br>Despite the unquestionable fraud by Rupp his experiments and collaboration with Einstein might have had a positive influence on the further progression to quantum mechanics. The two present papers became of seminal importance in the discussions between Bohr and Heisenberg which eventually in 1927 resulted in Heisenberg publishing his landmark thesis on the uncertainty principle. When Max Born received the Nobel Prize in physics he stated that: "An idea of Einstein gave me the lead From the present paper. He had tried to make the duality of particles-light quanta or photons-and waves comprehensible by interpreting the square of the optical wave amplitudes as probability density for the occurrence of photons."<br><br>Boni 160; Weil 153. unknown‎

The purpose of "A theorem in probability and its application in the Theory of radiation" is to demonstrate that the failure of statistical mechanics with respect to the radiation law Rayleigh - Jeans law contradicted by experience cannot be removed by the conjecture that perhaps the individual statistical events should not follow the usual law of independence product of probabilities instead of assuming a certain interdependence between them. Lanczos. The second paper "Statistical investigation on of the motion of an oscillator in a radiation field" makes use of the results of the previous investigation. Einstein's aim is to demonstrate that the Rayleigh-jeans law of radiation contracdicted by the physical facts is an unavoidable consequence of statistics even if we avoid any kind of assumption which may be suspected of needing correction.

Einstein's close personal friend Rabbi Julius Silberfeld was the rabbi of Temple B'nai Abraham in Newark New Jersey from 1902 to 1939. After it became clear that he could not return to Germany with Hitler's rise to power during his 1933 visit to the United States Einstein resided in England and Belgium for several months before returning to the U.S. where he accepted a position at the Institute for Advanced Study in Princeton New Jersey noted for having become a refuge for scientists fleeing Nazi Germany. It was here that he likely met and formed a close bond with Rabbi Silberfeld. The recipient of the letter Hugo Bergmann was the first rector of the Hebrew University of Jerusalem between 1935 and 1938 which Einstein was instrumental in establishing in 1925 and was among its first Board of Governors.

‎Autograph Letter Signed ALS Denouncing Racial Segregation‎

‎Princeton NJ: np 1943. First edition. nb. Fine. EINSTEIN OFFERS STRONG AND PRESCIENT WORDS OF ENCOURAGEMENT TO THE LEADER OF THE NAACP IN THE FIGHT AGAINST RACISM AND SEGREGATION IN THE UNITED STATES. Background: Einstein's fight against racial discrimination in the United States: The imperative "to protect the rights of the individual. was Einstein's most fundamental political tenet. Individualism and freedom were necessary for creative art and science to flourish. Personally politically and professionally he was repulsed by any restraints. "That is why he remained outspoken about racial discrimination in America. As a Jew who had grown up in Germany Einstein was acutely sensitive to such discrimination. 'The more I feel an American the more this situation pains me' he wrote in an essay called 'The Negro Question' for the January 1946 issue of Pageant magazine. 'I can escape the feeling of complicity in it only by speaking out.'" Isaacson Albert Einstein 505. Even more directly in his 1946 commencement speech to Lincoln University the first degree-granting Historically Black College and University HBCU in the United States Einstein strongly denounced segregation as "an American tradition which is uncritically handed down from one generation to the next" noting that "There is separation of colored people from white people in the United States. That separation is not a disease of colored people. It is a disease of white people. I do not intend to be quiet about it." This remarkable letter - from 1943 - is one of the earliest examples of his interest in condemning racism in the United States. The letter: Dated 22 September 1943 and handwritten on his embossed Mercer Street Princeton letterhead Einstein writes in English to Walter F. White the enormously influential African-American civil rights leader who led the NAACP from 1929-1955 praising him for his work and revealing his own awareness of and frustrations with racism and prejudice in America. 
 The text reads in full: Dear Mr. White: I have been quite impressed by the address you delivered some years ago at a meeting of the Princeton Branch of the National Association for the Advancement of Colored People. I know how hard it is to awaken the conscience even of good-hearted and well-meaning people when deep rooted prejudices are in the way. It is a great work indeed which you are doing relentlessly for the betterment of the living conditions of our Colored fellow-citizens for justice and for the accomplishment of national unity of the American people. With sincere respect and kind wishes Yours Albert Einstein ------------- On April 28 1940 White was the keynote speaker at "an inter-racial meeting sponsored by the Princeton branch of the National Association for the Advancement of Colored People" where his topic was "What Happens to Democracy When It Encounters the Color Line." Princeton Herald April 26 1940. At the time Princeton did not admit African Americans and the community was debating the question of whether or not to end segregation at the university. Princeton in fact did not admit its first African-American student until the fall of 1947. Einstein - writing in 1943 - notes that he heard White speak "some years ago". Something clearly must have deeply impressed Einstein about White's speech for him to write this thoughtful letter to White over three years after the event. Note: In addition to its content this apparently unpublished letter is also remarkable for being one of the very few letters Einstein hand-wrote in English during this period as German was still very much his preferred tongue. Princeton: September 22 1943. One page on Einstein's embossed Mercer Street Princeton letterhead 7.25x10 in visible handsomely matted and framed with a photograph of Einstein. Fine condition. np unknown books‎

Einstein's correction to his formula for the viscosity coefficient = 1 a key equation in his 1905 doctoral thesis in which he had presented a new theoretical method for determining molecular radii and Avogadro's number. In 1910 Jacques Bacelin a pupil of French physicist Jean-Baptiste Perrin obtained experimental results indicating a possible error in Einstein's formula. "That prompted Einstein after an unsuccessful attempt to find an error to ask his student and collaborator Ludwig Hopf to check his calculations and arguments . . . Hopf did find an error in the dissertation namely in the derivatives of some velocity components and obtained for a corrected coefficient 2.5 . . .In early 1911 Einstein submitted his correction for publication and recalculated Avogadro's number. He obtained a value of 6.56 x 1023 per mole a value that is close to those derived from kinetic theory and Planck's black-body radiation theory" Duplantier pp. 216-217.
