In fine condition. Translated and edited with an introduction by Leon Simon. An exceptional presentation. Einstein was a prominent supporter of both Labor Zionism and efforts to encourage Jewish-Arab cooperation. He supported the creation of a Jewish national homeland in the British mandate of Palestine but was opposed to the idea of a Jewish state "with borders an army and a measure of temporal power." In a letter to Jawaharlal Nehru dated June 13 1947 he asserted "Long before the emergence of Hitler I made the cause of Zionism mine because through it I saw a means of correcting a flagrant wrong.The Jewish people alone has for centuries been in the anomalous position of being victimized and hounded as a people though bereft of all the rights and protections which even the smallest people normally has.Zionism offered the means of ending this discrimination." Einstein's speeches lectures and letters concerning Zionism were first published in 1930 by The Soncino Press and eleven of these essays were later collected in The World as I See It published in 1933 which Einstein dedicated "to the Jews of Germany".

réf. 504141 First Edition journal issue. The brilliant follow-up to Einstein's landmark 1905 paper on the photoelectric effect. In the 1905 paper Einstein had explained the photoelectric effect-the emission of electrons from a metal when irradiated by light-by making the revolutionary proposal that light rather than consisting of continuous waves was instead made up of discrete particles of energy "light quanta" which transferred their entire payload of energy to an electron on impact. In the 1905 paper Einstein made use of Planck's mathematical formula for blackbody radiation which had introduced the concept of energy quanta but he was only able to derive part of the formula. In his 1906 paper Einstein "used his statistical mechanics to demonstrate that when light interacts with matter Planck's entire formula can arise only from the existence of light quanta-not from waves" Cassidy; emphasis ours. Einstein had realized as he stated in the present paper that "'Planck's theory makes implicit use of the . . . light-quantum hypothesis' . . . his acceptance of Planck's formula albeit as a hypothesis led to a major advance in his own work" Pais Subtle is the Lord p. 378.

Original printed wrappers. 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.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.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. 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."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 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".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.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."Boni 160; Weil 153. unknown

This volume was dedicated to Albert Einstein and is the only book that was ever written by "The Father of the Zoom Lens". With / An original black & white silver gelatin 5 x 7 photograph of Dr. Albert Einstein and Dr. Frank Gerald Back seated together in very fine condition acquired directly from Dr. Back's estate. This photograph was taken circa 1954 and is one of the images published in this limited edition. With An 18" x 22" blueprint folded of the Solar Eclipse Spectrograph size "C" drawing. It was made from the original drawing dated 4/1/55 drawn by Zoomar's Chief Designer Alfred Joseph Quittner "AJQ" & approved by Dr. Back "FGB". A very interesting package indeed. Dr. Back was a very close friend of Albert Einstein. Dr. Einstein persuaded the author to take the trip commemorated in this beautifully produced volume in order to capture the total eclipse of the sun which occurred on June 20 1955. Dr. Back intended to provide conclusive evidence for Einstein's theory of relativity by calculating the optical distortion if any of starlight caused by the sun's gravity. Earlier in 1919 Einstein's general relativity principles were supported by observations of a solar eclipse. The two scientists conferred on the project for over a year. Armed with a special Zoomar designed & built wide-angle solar-eclipse spectrograph Dr. Back was off to the Philippine Islands to board a military jet & chase the eclipse. Einstein however died while Back was on his way to Manila. Unable to report the excursion to his friend Dr. Back dedicated this book to his memory. Dr. Frank Back held over 200 patents directly relating to photographic equipment. He was the founder & president of Zoomar Inc. The photographic term " zoom" was derived from Zoomar. Dr. Back created the first widely used zoom lenses for motion picture and television; then in 1959 introduced the first zoom lens for still cameras with the introduction of the 36-82mm/f2.8 Voigtlander Zoomar. Dr. Back & Zoomar purchased the great Heinz Kilfitt optical factory of Munich Germany in 1966 & it became a subsidiary of Zoomar Inc. This volume was never widely distributed & when Zoomar Inc. ceased operations at Glen Cove Long Island many cases of this book were discovered & unceremoniously trashed. The existing number of copies is unknown but the book is not frequently encountered. This copy came from the personal estate of Dr. Frank Gerald Back & it is one of the few copies signed by him. An excellent example suited for collectors of Science Astronomy Einstein Zoomar or Photographic History in general.

"Professor Einstein is better known as a physicist than as a Zionist. Yet for many years he has given abundant proof both of a keen interest in Zionism and of a penetrating insight into its underlying ideas. He is impelled to Zionism by his acute consciousness of the excessive price at which the blessings of assimilation are bought by the Jewish communities of the Western world which for him are mainly represented by that of Germany. The price is a loss of solidarity of moral independence and self-respect. These in his view can be regained only if assimilated Jews find some common task of absolute human value to which they can bend their corporate energies as Jews. Such a task is to be found in the restoration of Jewish national life in Palestine." - Introduction. Unmarked with average wear. Backstrip lettering faded. Binding tight.

Einstein and Ehrenfest then showed that Pauli's results could be obtained by an extension of Einstein's 1917 paper with the unnecessary specialization to discrete energy levels removed . . . The core of Einstein's argument is that the scattering process should be broken into two parts: the absorption of energy from radiation of frequency 1 and the emission of energy as radiation of frequency 2" Lewis p. 42.
