1936H40351New York: Amateur Astronomers Association 1936. Very good. Old cloth 3-ring binder with acetate sheaths containing the issues. This started out as a 4 pp. periodical but expanded in later issues. In 1936 the journal merged with The Sky published by Hayden Planetarium which subsequently merged with The Telescope in 1941 to become Sky & Telescope which is still being published. Condition is mainly very good although the first three issues we have have some damage to fore-edges. The first issue has a supplementary sheet laid in "Professor Einstein Sends Greetings to the Amateur Astronomers Association" reprinting in facsimile the handwritten note with a printed translation and a facsimile of another note from Einstein. We have Vol. I nos. 1 & 2 April and May 1929; Vol. 2 nos. 1 September 1929 - 9 May-June 1930 -- the April 1930 issue has a cover story on the discovery of Pluto then considered the ninth planet. Pluto was first discovered on February 18 1930 by Clyde Tombaugh at the Lowell Observatory in Flagstaff Arizona.The discovery was announced on March 13 1930 in the Astronomical Journal.; Vol. III nos. 1 October-November 1930 - 7/8 May-June 1931; Vol. IV nos. 1 September-October 1931 - 8 Summer 1932; Vol. V nos. 1 September-October 1932 - 3 March 1933 -- these expanded to 6 pp. each; Vol. VI nos. 1 - 3 Winter & Spring 1933-1934 - Summer 1934 -- beginning with Vol. VI these are 16 pp. each; with the Spring issue cover story on Hayden Planetarium; Vol. VII nos. 1 Autumn 1934 - 3 Spring 1935; Vol. VIII nos. 1 Autumn 1935 - 3 Spring 1936.

1944182569London: The Jewish Agency for Palestine 1944. First separate edition of Einstein's appeal for Zionism. Einstein was one of the most prominent international supports of Zionism. He argues Palestine is the only place historically spiritually and culturally tied to the Jewish people. Whereas the Arabs with many homelands the Jews have nowhere else to go. Their claims are rooted not in conquest or nationalism but in justice and survival. The article was originally published in the Princeton Herald earlier that year. This publication prints the article alongside other speeches and letters by Einstein extracted from his 1930 About Zionism. Provenance: Jews' College Library London with their shelf mark to the front wrapper and their stamp to the front wrapper verso. Octavo. Original wrappers.

By assuming that the speed of light is the same to every observer moving at a constant velocity Einstein showed that space and time were not independent: spacetime was born. According to Hermann Weyl in 1918 this theory ‘led to the discovery that time is associated as a fourth coordinate on an equal footing with the other three coordinates of space and that the scene of material events the world is therefore a four-dimensional metrical continuum.' It was a revolutionary piece of scientific work" Calaprice The Einstein Almanac 15. <br /> <br /> In the second work Einstein uses "the postulates of the special theory of relativity Einstein showed that energy radiated is equivalent to mass lost.

19162364Braunschweig: Druck und Verlag von Friedr Vieweg and Son 1916. First edition. Original wrappers. Very Good. FIRST PRINTING IN ORIGINAL WRAPPERS OF ONE OF EINSTEIN'S MAJOR WORKS: HIS FIRST PAPER ON THE DERIVATION OF PLANK'S LAW AND PROVIDING THE THEORETICAL BASIS FOR THE LASER. "Einstein commended the 'unparalleled boldness' of Planck's derivation of 1900 meaning not only the problem itself but also the fact that it was based on assumptions that were not entirely free of contradictions. Einstein now succeeded in the first of two papers in eliminating that flaw. More interesting than the derivation itself was the general character of his methods. Einstein proceeded from Niels Bohr's basic--and by then well tested--assumption that the electrons within an atom occupy a number of discrete energy states and are able through emission or absorption of radiation to pass from one of those states to another. Added to this was an assumption of thermodynamic equilibrium between radiation field and atom as well as a consideration of the 'classical' limiting case at high temperatures--and there was Planck's formula. This brief argument. also covers emission stimulated by the radiation field; thus the formulas already by implication contain the theory of the laser though it was to take nearly half a century to be realized" Folsing Albert Einstein 389. Weil 85.<br /> <br /> The "implication" containing the theory of the laser was more fully developed in his companion paper "On the Quantum Theory of Radiation" published a few weeks later. In the first paper Einstein wrestled with the concept that the atomic emission of radiation could be a directed process; in the second paper he convincingly demonstrates that this is indeed the case.<br /> <br /> IN: Verhandl.

19161614Braunschweig: Druck und Verlag von Friedr. Vieweg and Son 1916. 1st Edition. FIRST EDITION OF AN IMPORTANT WORK BY EINSTEIN: HIS FIRST PAPER ON THE DERIVATION OF PLANCK'S LAW HERE INTRODUCING THE THEORY OF THE STIMULATED EMISSION OF ELECTROMAGNETIC RADIATION INTO THE QUANTUM THEORY. "EINSTEIN'S CONCEPT OF STIMULATED EMISSION IS THE OPERATING PRINCIPLE OF THE NOW UBIQUITOUS LASER" Brandt Harvest of the Century 136. <br /> <br /> In 1900 Max Planck laid the foundation for quantum theory with his publication of Planck's law. Though Einstein commended Planck in his own "light-quantum hypothesis of 1905 he Einstein postulated that the energy quantization is a property of the radiation field itself and not due to the material resonators as Planck believed" ibid. "Einstein found a similarity between a cavity filled with radiation consisting of quanta and a vessel filled with gas consisting of atoms" Brandt Harvest of the Century 136. Einstein believed that "although either part of Planck's derivation was in itself consistent their combination was logically incompatible.For Einstein this inconsistency was no reason to reject Planck's quantum theory as such" it was a reason to study the foundations of traditional radiation theory and if needed revise them Jammer The Conceptual Development of Quantum Mechanics 26. <br /> <br /> "After completion of his general theory of relativity in 1916 Einstein was able to derive Planck's original quantum law to his satisfaction "by considering the possible interactions between radiation and matter" Brandt. From there he was able to suggest that in addition to spontaneous emission and absorption a process of stimulated emission could also take place. <br /> <br /> In Einstein's derivation of Planck's law he treats "the interaction between light quanta and atoms in the formalism of his A and B coefficients. They describe the probabilities for the absorption and emission of a light quantum of a given energy. The probability of absorption is of course proportional to the density of the radiation of that frequency. The emission is in part spontaneous like radioactivity but there is also stimulated emission which again is proportional to the density of the radiation of that frequency ibid. This is one of two papers Einstein wrote on the subject. <br /> <br /> Einstein's derivation "predicted that as light passed through a substance it could stimulate the emission of more light. This effect is at the heart of the modern laser" The Quantum and the Cosmos I History AIP portal. CONDITION & DETAILS: Braunschweig: Druck und Verlag von Friedr.

EINSTEIN'S FIRST ATTEMPT AT A UNIFIED FIELD THEORY" PAIS<br /> HANS ALBERT EINSTEIN'S COPY OF THE PRESENTATION OFFPRINT. <p>First edition extremely rare author's presentation offprint 'Überreicht vom Verfasser' and the copy of Einstein's son Hans Albert of "Einstein's first attempt at a unified field theory" Pais Subtle is the Lord p. 287. Once Einstein completed work on the general theory of relativity at the end of 1915 "his attention shifted to the search for a unified theory of the electromagnetic and gravitational fields out of which he hoped to be able to explain the structure of matter. Quantum effects were to be derived from such a theory rather than postulated ad hoc. This remained his approach for the rest of his life" Cao Conceptual foundations of quantum field theory pp. 166-167. "As so often the case in relativity the story of quantum gravity begins with Einstein himself. Soon after the final formulation of general relativity he pointed out the need for a quantum modification of the theory. In his first paper on gravitational radiation the 1916 paper 'Näherungsweise Integration der Feldgleichungen der Gravitation' 'Approximate Integration of the Field Equations of Gravitation' Einstein argued that quantum effects must modify the general theory of relativity. Two years later he reiterated this conclusion the 1918 paper 'Über Gravitationswellen' 'On Gravitational Waves': 'As already emphasized in my previous paper the final result of this argument which demands a gravitational energy loss by a body due to its thermal agitation must arouse doubts about the universal validity of the theory. It appears that a fully developed quantum theory must also bring about a modification of the theory of gravitation.' Einstein writing in the 1919 paper offered here soon began to speculate whether gravitation plays a role in the atomistic structure of matter: 'There are reasons for thinking that the elementary formations which go to make up the atom are held together by gravitational forces. The above reflections show the possibility of a theoretical construction of matter out of the gravitational field and the electromagnetic field alone' In order to construct such a model of an 'elementary particle' Einstein shows that it is necessary to modify the original gravitational field equations .The major interest of this paper is that his attention now shifted from possible quantum modifications of general relativity to the search for a unified theory of the electromagnetic and gravitational fields on the basis of which he hoped to explain the structure of matter. Quantum effects are to be derived from such a theory rather than postulated ad hoc. Einstein remained committed to this approach for the rest of his life: the search for a 'natural' mathematical extension of the general theory in the hope that such a theory would somehow explain the quantization of matter and energy" Iyer and Bhawal Black Holes Gravitational Radiation and the Universe pp. 525-526. Einstein's work on unified field theory was inspired by James Clerk Maxwell's success in finding a unified theory of electricity and magnetism one of the greatest achievements of nineteenth century physics which showed that light was a form of electromagnetic wave and made possible modern inventios such as radio television and the telephone. Einstein continued his attempts to devise a unified theory of gravitation and electromagnetism for the rest of his life; his contributions in this area represent about a quarter of his entire research output and half his scientific production after 1920. Although he was ultimately unsuccessful a similar vision was realized in the decades after his death in the construction of the 'standard model' a unified theory of electromagnetism with the weak and strong nuclear forces which were unknown in Einstein's time and efforts to incorporate gravity into the model continue to this day. RBH lists three copies. OCLC lists only one copy none in US.</p> <br /> <p>Provenance: Hans Albert Einstein 1904-73 ink stamp and pencil notes on front wrapper. Hans Albert Einstein was a Swiss-American engineer and educator the second child and first son of physicists Albert Einstein and Mileva Marić. He was a long-time professor of hydraulic engineering at the University of California Berkeley.</p> <br /> <p>"As early as 1909 in his fundamental paper 'Zum gegenwärtigen Stand des Strahlungsproblems' 'On the current status of the radiation problem' which resulted from a discussion with Walter Ritz Einstein remarks 'dass des elektrische Elementarquantum e ein Fremdling ist in der Maxwell-Lorentzschen Elektrodynamik' 'that the electrical elementary quantum e is alien to Maxwell-Lorentz electrodynamics'. Einstein expressed the hope that 'die gleiche Modifikation der Theorie welche das Elementarquantum e als Konsequenz enthält auch die Quantenstruktur der Strahlung als Konsequenz enthalten wird' 'the same modification of the theory which contains the elementary quantum e as a consequence will also contain the quantum structure of radiation as a consequence'. Pauli 1949 in his review about 'Einstein's Contribution to Quantum theory' pointed out that though quantum theory later on deduced the quantum structure of radiation it has not solved Einstein's first problem and the elementary charge 'auch in der Quantenmechanik ein Fremdling geblieben ist' 'has also remained alien to quantum mechanics'. He emphasized that just this fact had been one of the strongest arguments to Einstein against the finality of the steps leading to quantum mechanics.</p> <br /> <p>"So during his Berlin years Einstein made it his task to find a synthesis of his general theory of relativity GRT and the then nascent quantum physics. In this connection he attributed logical primacy to the relevant relativistic field theory because it had reached a high degree of maturity in the GRT. After all Einstein's general-relativistic gravitation theory is the first theory on the fundamentals of physics working with genuinely non-linear equations and Einstein observed that such a nonlinearity is necessary for understanding the existence of the 'discrete field-quanta.' A linear theory allowing arbitrary superposition of fields would without further restrictions in the form of boundary and uniqueness conditions never lead to a discrete spectrum of solutions. But recourse to such restrictions means that the fields are held together by the operation of entities outside the scope of the theory .</p> <br /> <p>"In Einstein's view the problem of incorporating the elementary particles into field physics involved the question of finding field-theoretical models of electrons and protons which were the only known particles at that time. Einstein searched for solutions or general-relativistic field equations for the combined gravitational and electromagnetic fields representing mass and charge distributions with central symmetry and he hoped there would emerge self-consistent solutions only for discrete values of the mass and charge parameters i.e. for a 'particle spectrum.'</p> <br /> <p>"This 'Einstein particle problem' pursued ideas that had been developed already in the framework of the special theory of relativity and the Maxwell-Lorentz electrodynamics for instance in the nonlinear theory of the electromagnetic field by G. Mie and D. Hilbert. As an essential progress by the general-relativistic treatment Einstein regarded the genuine nonlinearity of the field equations which Mie and Hilbert had to introduce ad hoc and full consideration of the particle dynamics in the sense of the general-relativistic problem of motion. The generalizations of the Maxwell equations considered by Mie and Hilbert contain a too small number of components for the integrability conditions to determine the particle dynamics whereas the Einstein problem of motion in the GRT furnishers just this dynamics as a consequence of the integrability conditions for the field equations of gravitation. It is the GRT that with its metric field for the first time embraces inertia and gravity that is just those properties which are characteristic of all particles.</p> <br /> <p>"Einstein in fact succeeded in driving self-consistent gravitational and electromagnetic fields which can be interpreted as particle models of that kind. But his success depended on a weakening of his own equations of gravitation which physically amounts to the introduction of an additional hypothetical cosmical field of the 'Poincaré pressure.' By this weakening it becomes possible to set up self-consistent particle models with spherical symmetry for arbitrary centrosymmetric mass and charge distributions. In 1919 Einstein presented his result to the academy in his paper 'Spielen Gravitationsfelder im Aufbau der materiellen Elementarteilchen eine wesentliche Rolle' His answer to the question says that in his particle models the electrical field energy contributes ¾ and the gravitational energy ¼ of the total energy.</p> <br /> <p>"Einstein's first discourses on the particle problem in the GRT were closely related to the 1917/18 papers in which he laid the foundations of relativistic cosmology. In his Academy report 'Kosmologische Betrachtungen zur allgemeinen Relativitätstheorie' 'Cosmological considerations on the general theory of relativity' 1917 Einstein had by introducing the term λgμν with the 'cosmological constant' λ extended his equations of gravitation to his cosmological equations of gravitation</p> <br /> <p>Rμν - ½ gμνR λgμν = - κ Tμν . </p> <br /> <p>He could show that these equations permit as a particular solution with λ > 0 and constant positive mass density a statical model of the universe representing a closed spheric or elliptic three devotional Riemannian space .</p> <br /> <p>"In his paper of 1919 about the role of gravitation in the structure of elementary particles Einstein also interpreted the cosmological constant λ as the universal 'Poincaré' pressure' which according to a hypothesis of H. Poincaré is to guarantee the stability of Lorentz's electrons against their own repulsion forces. Einstein's ideas concerning this matter partly resulted from a controversial discussion with E. Schrödinger 1918 about the gravitational energy in the GRT and the structure of the energy tensor" Treder pp. 149-151.</p> <br /> <p>Indeed Schrödinger had pointed out another way of treating the cosmological constant: moving it from the left-hand side of equation where it represents a contribution to space-time curvature to the right-hand side where it represents a contribution to the energy-matter distribution. Then it would correspond physically to a kind of cosmic pressure. Schrödinger believed this might be the pressure postulated by Poincaré to maintain the stability of charged particles: an electric charge on the surface of a sphere creates a force pushing outwards so without any opposing force the charged sphere would explode outwards. </p> <br /> <p>Einstein never liked the cosmological constant. In the present paper he acknowledged that his introduction of the cosmological constant was "gravely detrimental to the formal beauty of the theory" Cambridge Companion to Einstein p. 257.</p> <br /> <p>Boni-Russ-L. 111; Schilpp 123; Weil 106.

Einstein is known for developing the theory of relativity which is one of the two pillars of modern physics. His work greatly influenced the philosophy of science and for producing the world's most famous equation 'E= mc2'. He won the Nobel Prize in Physics in 1921 for his services to theoretical physics and for his discovery of the law of the photoelectric effect. The papers to this work include Einstein's papers on Bose-Einstein condensation the phenomenon that causes bosons to become a superfluid at low temperatures. There is also Einstein's two part commentary on Kaluza's theory involving field equations in five-dimensional space.

193313747Los Angeles 1933. Signed by the photographer Aaron Tycko of Los Angeles. Prominently signed “Albert Einstein. 1933†below image. Rarely seen photograph of the famous scientist taken during his last visit to Southern California in January 1933 the month Hitler took power in his native Germany. During the five-month trip Einstein 1879-1955 spent most of his time at the Mount Wilson Observatory and the California Institute of Technology where he was offered a position. Later that year he renounced his German citizenship and accepted a professorship at the Institute for Advanced Studies in Princeton New Jersey.<br /> <br /> Tycko 1893-1975 was based in Los Angeles and often photographed Einstein along with other Hollywood icons of the early twentieth century including Irving Berlin. At the time this photograph was taken Tycko also shot a well-known photograph of Einstein with his wife Elsa. Interestingly Tycko is mention in Einstein’s FBI files because a Hollywood informant reported that the photographer believed Einstein was a communist. This informant contended that Tycko thought Einstein was “the brain that was setting up Hollywood in the 1930’s for the big Communist push . . . He was one of the most dangerous and powerful figures in what has become the Communist movement.†<br /> <br /> Jerome The Einstein File: J.
