In his landmark 1905 paper on special relativity Einstein used the velocity-dependent concepts of transverse and longitudinal mass for the moving electron these terms have now been replaced with the concept of relativistic mass first defined by Lewis and Tolman in 1909. In the present paper Einstein proposed an experimental method for determining the ratio of the transverse to the longitudinal mass and invited experimentalists to verify his special theory of relativity. Einstein later abandoned velocity-dependent mass concepts stating in 1948 that "it is better to introduce no other mass concept than the rest mass" quoted in L. B.

Rayleigh was born as the son of John James Strutt second Baron and his wife Clara Elizabeth La Touche eldest daughter of Captain Richard Vicars R.E. Lord Rayleigh was awarded the 1904 Nobel Prize in Physics "for his investigations of the densities of the most important gases for his discovery of argon in connection with these studies." Rayleigh provided the first theoretical treatment of the elastic scattering of light by particles much smaller than the light's wavelength now known as "Rayleigh scattering" - a process which notably explains why the sky is blue. He also made extensive contributions to fluid dynamics e.g. the Rayleigh number critereon for the stability of the Taylor-Couette flow etc. Rayleigh also formulated the circulation theory of aerodynamic lift. His derivation of the Rayleigh-Jeans law for classical black body radiation played an important role in the birth of quantum mechanics i.e. the Ultraviolet catastrophe. During the first World War he was president of the United Kingdom government's Advisory Committee for Aeronautics. Notable students of the 3rd Lord Rayleigh include J.J. Thomson 1856-1940 and Sir William Ramsay 1852-1916 who was awarded the Nobel Prize in Chemistry in 1904 "in recognition of his services in the discovery of the elements in air." In 1871 he married Evelyn Balfour sister of the future prime minister the Earl of Balfour and daughter of James Maitland Balfour and his wide Blanche the daughter of the second Marquis of Salisbury. They had three sons the eldest of whom Robert John Strutt 1875-1946 was to become Professor of Physics at Imperial College of Science and Technology London.

In 1916 after publishing his great work on general relativity Einstein returned to the question of blackbody radiation. In November 1916 he wrote to his friend Besso that "a splendid light has dawned on me about the absorption and emission of radiation" quoted in Pais p. 405 one that led him to a new derivation of Planck's radiation law and convinced him of the reality of light-quanta photons. After publishing these results in three papers culminating with the famous "Zur Quantentheorie der Strahlung" 1917 Einstein kept looking for "new ways in which the existence of photons might lead to observable derivations from the classical picture" Pais p. 413. He found none until 1923 when Arthur Compton and Peter Debye independently derived the relativistic kinematics for the scattering of a photon off an electron at rest. The work of Compton and Debye led Wolfgang Pauli to extend Einstein's work of 1917 to the case of radiation in equilibrium with free electrons see Pais p. 414n. "Pauli examined the requirements of detailed balance under Lorentz transformations and found that scattering of light by free electrons must include a term of a form which we would now call stimulated emission . . . 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.

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".

1940180281Princeton: Princeton University Press 1940. Elucidating the Einstein-Infeld-Hoffman equations First edition offprint issue of Einstein's last major contribution to the general theory of relativity. It formed part of his mathematical investigations into the structure of the theory which he spent the latter part of his life refining. "During the development of the general theory Einstein had intended to hold fast to the conservation of energy and momentum in the usual special relativistic sense as far as possible. At the same time he was driven by other considerations toward the idea that the laws should be generally covariant. These two desires proved mutually incompatible. The problem of the equation of motion of bodies is the following. The 1916 theory had a classical structure in the sense that there were both field equations the curvature of space-time is determined by the mass and motion of bodies in space-time and equation of motion of bodies the world line of small mass is a geodesic. Einstein showed that if matter is represented by a point singularity of the metric field these singularities are located on world lines that are geodesics of space time provided its metric satisfies the equation of general relativity" DSB IV p. 329.

Blackett' see below with Blackett's ownership inscription in blue ink to front free endpaper.First English edition with a preface by Einstein of this work arguing for nuclear disarmament translated by the gardener novelist and anarchist Edward Byams this copy from the library of Nobel Prize-winning physicist Patrick Blackett whose own work is discussed at length in the book.Jules Moch 1893-1985 worked as a French Resistance organiser during the war later became a senior minister in several post-war governments and was France's delegate to the UN Disarmament Committee for 1951-1960. It was this latter role that informed the principles he sets forth in Human Folly which argue for multilateral nuclear disarmament. Divided into two parts the first examines the destructive capacities of modern warfare before tracing the recent history of disarmament negotiations. Moch attempts to represent both Soviet and Western positions with fairness concluding that the divisions between the two are gradually narrowing. Though he does not regard the situation as entirely hopeless he presents it as one of pressing urgency. The preface by Albert Einstein one of Moch's most eminent supporters makes clear peace can only arise from political will: 'Those who do not believe in the possibility of the attainment of a lasting and assured peace or have not the courage to act accordingly are ripe for destruction' p. 8. Provenance: front free endpaper with the ownership inscription of Patrick Blackett 1897-1974 with his occasional underlining throughout and one word 'Target' in pencil to the top of p. 10. Blackett was awarded the 1948 Nobel Prize in Physics for his pioneering work in nuclear physics and cosmic radiation including experiments demonstrating nuclear transmutation and important early research into the positron. During the Second World War he headed Operational Research at the Admiralty where his statistical criticism of the RAF blanket bombing campaigns led to increasing ostracism from the military authority. His opposition to mass destruction later informed his belief that Britain should not develop nuclear weapons. Combined with his openly socialist views this attracted the attention of MI5 and led to his inclusion on George Orwell's list of alleged 'crypto-communists' contributing to his marginalisation by the post-war Labour government. Blackett's book The Military and Economic Consequences of Atomic Energy 1948 is discussed at length by Moch pp. 117-19. Written before the development of second-generation thermonuclear weapons Blackett had estimated that thousands of atomic bombs would be required to destroy the United States or the Soviet Union when at the time only a few dozen existed. As Moch observes on p. 121 however 'today a few dozen thermonuclear bombs would produce the same results'. It is particularly notable that Blackett has not annotated the passages explicitly discussing his work. This copy of Human Folly is offered with Blackett's pamphlet The Atom and the Charter which discusses the extent to which 'the advent of atomic bombs necessitates changes in the procedure for the application of sanctions under the Charter of the United Nations Organisation' issued by Victor Gollancz and the socialist Fabian Society on behalf of the Association of Scientific Workers a scientific trade union of which Blackett was president. hardcover

SCIENTIFIC FRAUD: THE EINSTEIN-RUPP EXPERIMENTS. <p>First edition extremely rare author's presentation offprint not to be confused with the much more common trade separate - see below from the library of the great German physicist Arnold Sommerfeld of the notorious Einstein/Rupp experiments. "In the fall of 1926 Albert Einstein published the outline of two experiments in the Proceedings of the Berlin Academy. They addressed one of the most urgent questions in physics at the time: the experiments were to show if the emission of light was a process that was extended in time or if instead light emission occurred in an instantaneous act. Of course the first possibility would confirm a traditional oscillator-and-wave-like view whereas the second possibility would cohere well with Einstein's own ideas on light quanta. It is quite surprising that these experiments are so unfamiliar today. Apart from addressing a central question and being proposed by no lesser figure than Einstein they also circulated at a crucial moment in the history of quantum theory. Still the experiments are not mentioned in any of the standard Einstein biographies and there is no substantial treatment of them in histories of the quantum theory . The likely cause for this lack of attention is at least as surprising: the experiments were-supposedly-conducted by Emil Rupp yet a decade later Rupp was exposed as a scientific fraudster; the results obtained by Rupp in close consultation with Einstein and published back-to-back with the latter's theoretical paper were in the end generally believed to have been fabrications" Van Dongen. As Walter Gerlach of Stern-Gerlach fame said in an interview with Thomas Kuhn in 1963 "Rupp in the late twenties early thirties was regarded as the most important and most competent physicist. He did incredible things. . Later it turned out that everything that he had ever published everything was forged. This had gone on for ten years ten years!" Nevertheless "these experiments played a substantial role in developments in 1926. Most importantly they confirmed a wave picture of light when many including Einstein himself initially expected a particle-like instantaneous picture of light emission to be confirmed. After all only a few years before Compton scattering had been shown and as little as a year before the Einstein-Rupp experiments Walther Bothe and Hans Geiger had done the experiments that dismissed the BKS theory. But the experiments of Einstein and Rupp also influenced events in other ways. For instance their initial interpretation was most likely of direct importance for Max Born when he proposed the probabilistic interpretation of the wave function. The experiments further played a role in the thinking of Werner Heisenberg as he formulated his uncertainty relations . these experiments deserve renewed attention and their current obscure status is not warranted by their historical importance" Van Dongen. OCLC locates only three copies two in Switzerland one in Germany but it is unclear which of these if any are author's presentation offprints. The presentation offprint was not present in the collection of Einstein's son Hans Albert Christie's 2006 but it was in Einstein's own collection of his offprints Christie's 2008.</p> <br /> <p>Provenance: Arnold Sommerfeld 1868-1951 his characteristic numbering '46' in red pencil on front cover. "The son of a physician Sommerfeld was educated at the University of Königsberg. After teaching briefly at the universities of Göttingen Clausthal and Aachen he was appointed professor of physics at the University of Münich in 1906. Sommerfeld should have retired in 1936 in favour of his pupil Werner Heisenberg. Opposition from the Nazi party to Heisenberg's appointment prolonged Sommerfeld's tenure and it was not in fact until late 1939 that he finally retired to be succeeded not by Heisenberg but by Wilhelm Müller a Nazi aerodynamicist without a single publication in physics to his credit. Although Sommerfeld and Heisenberg were not Jewish they were regarded by the Nazis as Jewish sympathizers. Sommerfeld however survived the war and returned to his Münich chair in 1945 continuing to work at physics until he died in a car accident in 1951" Oxford Reference. "Arnold Sommerfeld was one of the most distinguished representatives of the transition period between classical and modern theoretical physics. The work of his youth was still firmly anchored in the conceptions of the nineteenth century; but when in the first decennium of the century the flood of new discoveries experimental and theoretical broke the dams of tradition he became a leader of the new movement and in combining the two ways of thinking he exerted a powerful influence on the younger generation. This combination of a classical mind to whom clarity of conception and mathematical rigour are essential with the adventurous spirit of a pioneer are the roots of his scientific success while his exceptional gift of communicating his ideas by spoken and written word made him a great teacher" Max Born p. 275. </p> <br /> <p>"Born in 1898 Rupp began his career in the 1920s studying canal rays beams of positive ions and atoms formed between an anode and cathode the latter punctured with holes or "canals" in a gas discharge tube. When these rays shoot through the canals and into a vacuum chamber the ions rapidly lose and gain charge emitting visible light that becomes less intense at the other end of the canal.</p> <br /> <p>"In his first experiments in the mid-1920s Rupp measured the coherence length of light - the distance over which the light maintains a consistent phase - emitted by hydrogen and mercury atoms in the canal rays. He measured these lengths as 62 centimeters for hydrogen and 15.2 centimeters for mercury. These were blockbuster results: A moving hydrogen atom was expected to stay coherent over a much smaller distance.</p> <br /> <p>"What's more Rupp's extra-long hydrogen canal ray seemed like it could be used to test one of physics' biggest questions at the time: Is light a particle or a wave Einstein had devised experiments to test if light was emitted instantaneously or over time but he needed a light with an extra-long coherence length - and only Rupp had achieved it.</p> <br /> <p>"After reading Rupp's 1926 paper Einstein published his own "Proposal for an Experiment on the Nature of the Elementary Process of Radiation Emission" and reached out to Rupp directly to discuss a collaboration. But because Rupp's boss at Heidelberg University the physicist Philipp Lenard was "a fervent anti-relativist - and anti-Semite" writes van Dongen Einstein chose to forgo a visit to the institution and sent instructions for Rupp to do the experiments on his own.</p> <br /> <p>"There were red flags from the start. In one instance Rupp appeared to have altered the mirrors in his interferometer the instrument he used to study interference just so into an arrangement that would obtain desired outcomes. In another instance when Einstein corrected the settings Rupp reported using for another instrument Rupp chalked the mistake up to a typo. There were other 'alarming discrepancies' in Rupp's calculations van Dongen writes and Einstein's letters show that he pushed back on several occasions. Each time Rupp responded with new results that perfectly explained the oddities Einstein questioned.</p> <br /> <p>"Initially Einstein expected to find that light was emitted instantaneously. But as the collaboration stretched on he began to expect the experiments would confirm the alternative the 'classical' theory. 'One of the reasons for his changing position likely was that that outcome had inadvertently already been corroborated by Rupp' van Dongen writes.</p> <br /> <p>"When Rupp furnished Einstein with a final set of results supporting the classical emission picture Einstein facilitated their publication in the proceedings of the Prussian Academy of Sciences. They were published back-to-back with a paper by Einstein explaining the theory behind the experiments in which Einstein cited Rupp's work. Einstein even helped Rupp draft his paper's abstract.</p> <br /> <p>"The association with Einstein rocketed Rupp to scientific prominence and in 1928 he accepted a position in the research labs of German electronics company AEG 'a kind of counterpart to General Electric' writes MIT physicist Anthony French in his 1999 retrospective of Rupp's case.</p> <br /> <p>"However scientists had begun voicing skepticism about Rupp's canal ray work. Among them were British spectroscopist Robert d'Escourt Atkinson who doubted Rupp's extraordinary coherence lengths and a researcher named Harald Straub who tried and failed to replicate Rupp's measurements in 1930. Rupp came down hard on Straub with a rebuttal sending photographs that supposedly showed his interference fields and forcefully defending his work in the same journal where Straub published his. Straub wrote that he had nothing else to add and the matter appeared settled.</p> <br /> <p>"But Rupp's reputation was bruised in the episode and his letters from the time indicate that his funding at AEG was drying up. He published work on electron scattering then took up experiments with positrons producing them by pounding lithium with protons. In a 1934 paper Rupp claimed to have accelerated protons at potential differences of 500 kV. This was impossible for him to have done - he simply did not have the requisite accelerator in his lab.</p> <br /> <p>"In December 1934 two of Rupp's fellow scientists at AEG brought the glaring problem to the attention of the institute's director who launched an investigation and subsequently fired Rupp. In January 1935 Rupp published the retraction statement appended to his doctor's note claiming he had no knowledge of or control over the fabrications. And later that year experimentalists Walther Gerlach and Eduard Rüchardt published 'On the Coherence Length of Light emitted by Canal Rays' which essentially confirmed that Rupp's early canal ray work was also erroneous. Amid this public humiliation Rupp experienced a nervous breakdown and spent time in a sanatorium. He never worked in physics again.</p> <br /> <p>"Einstein however escaped from the episode unscathed. Historians like van Dongen think his credulousness was an honest mistake underpinned by his desire to see his theories confirmed by experiments. Rupp's work and life are now a footnote but following his downfall it appears that German scientists mentioned his name often. According to French 'for a number of years afterward the word 'geruppt' became an epithet among German physicists to describe questionable work'" Jooss. </p> <br /> <p>This author's presentation offprint is of extreme rarity and must be distinguished from other so-called 'offprints' of papers from the Berlin Sitzungsberichte many of which are commonly available on the market. The celebrated bookseller Ernst Weil 1919-1981 in the introduction to his Einstein bibliography wrote: "I have often been asked about the number of those offprints. It seems to be certain that there were few before 1914. They were given only to the author and mostly 'Überreicht vom Verfasser' Presented by the Author is printed on the wrapper. Later on I have no doubt many more offprints were made and also sold as such especially by the Berlin Academy." If the term 'offprint' means as we believe it should a separate printing of a journal article given only to the author for distribution to colleagues then 'offprints' were not commercially available. Although there is certainly some truth in Weil's remark in our view it requires clarification and explanation.</p> <br /> <p>Until about 1916 most of Einstein's papers were published in Annalen der Physik; from 1916 until he left Germany for the United States in 1933 most were published in the Berlin Sitzungsberichte. The Sitzungsberichte differed from other journals in which Einstein published in that it made separate printings of its papers commercially available. These separate printings have 'Sonderabdruck' printed on the front wrapper the usual German term for offprint but they are not offprints according to our definition. They were available to anyone; indeed a price list of these 'trade offprints' is printed on the rear wrapper. True author's presentation offprints can be distinguished from these trade separates by the presence of 'Überreicht vom Verfasser' on the front wrapper.</p> <br /> <p>In the period 1916 to 1919 or 1920 the Sitzungsberichte trade separates are themselves rare. After 1919 or 1920 however the trade separates become much more common although the author's presentation offprints are still very rare. The reason for this change is that it was only in 1919 that Einstein became famous among the general public.</p> <br /> <p>It might seem obvious that Einstein's fame dates from 1905 his 'annus mirabilis' in which he published his epoch-making papers on special relativity and the light quantum. However these works did not make him immediately well known even in the physics community - many physicists did not understand or accept his work and it was two or three years before his genius was fully accepted even by his colleagues. Einstein did not secure an academic position until 1908. Among the general public Einstein became well known only in late 1919 following the success of Eddington's expedition to observe the bending of light by the Sun which confirmed Einstein's general theory of relativity. This was front-page news and made Einstein universally famous. See Chapter 16 'The suddenly famous Doctor Einstein' in Pais Subtle is the Lord for an account of these events. Before 1919 the trade separates of Einstein's papers would probably only have been purchased by professional physicists; after 1919 everyone wanted a memento of the famous Dr. Einstein whether or not they understood anything of theoretical physics and the trade separates of his papers were printed and sold in far greater numbers than before to meet the demand. It is telling that when these post-1919 trade separates appear on the market they are often in mint condition - they were never read simply because their owners were unable to understand them.</p> <br /> <p>BRL 160; Weil 153.

This classic in the history of physics is Einstein's second paper on the photoelectric effect. Einstein reconciles his and Planck's independent derivations of the blackbody formula E=hν. Planck's derivation of this formula ascribed it to a restriction on the energy changes possible when radiation is produced or absorbed by matter which implied no restriction on the energies of either matter or radiation. Einstein's 1905 derivation ascribed it to a restriction on the energy of radiation alone but in this paper he proposes the modern idea that the energies of both matter and radiation are quantized which led to his work on quantum specific heats.</p><p>and</p><p>FIRST EDITION of "The Principle of Conservation of Motion of the Center of Gravity and the Inertia of Energy" pp. 627-633.
