FIRST EDITION IN ORIGINAL WRAPPERS OF EINSTEIN'S LEIDEN LECTURE EXPLAINING AT LENGTH HIS THEORY OF THE ETHER ALONG WITH THOSE OF LORENTZ & MAXWELL. Very good condition. "Einstein's lecture at the University of Leiden on the occasion of his appointment as a visiting professor summarized his current views on the ether and retrospectively looked at the development of his opinions on the physical properties of space" Calaprice The Einstein Almanac 86. In this lecture Einstein recanted his earlier denial of the ether writing: "Recapitulating we may say that according to the general theory of relativity space is endowed with physical qualities; in this sense therefore there exists an ether. According to the general theory of relativity space without ether is unthinkable; for in such space there not only would be no propagation of light but also no possibility of existence for standards of space and time measuring-rods and clocks nor therefore any space-time intervals in the physical sense. But this ether may not be thought of as endowed with the quality characteristic of ponderable media as consisting of parts which may be tracked through time. The idea of motion may not be applied to it" Einstein Ather 1920. In this lecture Einstein also sought "to reconcile his theory of relativity with his mentor's Lorentz's cherished concept of the aether. Einstein stressed that special relativity took away the last mechanical property of Lorentz's aether: immobility. However he continued that special relativity does not necessarily rule out the aether because the latter can be used to give physical reality to acceleration and rotation. This concept was fully elaborated within general relativity in which physical properties which are partially determined by matter are attributed to space but no substance or state of motion can be attributed to that "aether" aether = curved space-time" Wikipedia.

1921réf. 1206201921. Signed. EINSTEIN Albert. Autograph letter signed. No place August 14 1921. Single sheet of cream lined paper measuring 7-1/2 by 11 inches; p. 1. $35000.Rare heartfelt autograph letter of recommendation written and signed by Einstein in German enthusiastically recommending his friend and colleague physicist Prof. Dr. Paul Epstein for an academic position.The autograph letter dated ""14 VIII 21"" written entirely in Einstein's hand reads translated from the original German: ""Prof. Dr. Epstein is certainly one of the most prominent living theoretical physicists of the German-speaking world. Without a doubt he would have been appointed to a German professorship a long time ago had his Russian nationality not stood in the way. Among Epstein's numerous original scientific papers two findings which advanced the modern quantum theory in crucial ways should be noted. After Mr. Sommerfeld as the first physicist who on the basis of special hypotheses had applied the quantum theory to a certain mechanical system of more than one degree of freedom Mr. Epstein discovered an important generalization of the quantum principle which established the application of the quantum theory for all quasi-periodic mechanical systems. Based on that general application of the quantum principle he then provided an analysis of the splitting of spectral lines in the electrical field Stark effect the accordance of which with the experiment provides one of the strongest supports for the Rutherford-Bohr atomic theory. I would like to add that I have also come to appreciate Mr. Epstein in personal interactions as a human being and that I had the pleasure of attending several scientific lectures given by him which enabled me to convince myself of his competence in delivering clearly understandable oral exposition. / A. Einstein.""Einstein and Epstein were friends and longtime correspondents who shared an interest in physics Judaism and the founding of Israel. Paul Epstein was a Russian-American mathematical physicist. He remains best known for his contributions to the development of quantum mechanics. Indeed he was one of a select group that included Lorentz Einstein Minkowski Thomson Rutherford Sommerfeld Rntgen von Laue Bohr de Broglie Ehrenfest and Schwarzschild. Born in Warsaw then part of Imperial Russia Epstein was brought up solidly middle class. He later stated that his mother recognized his potential at the age of four and predicted his future as a mathematician. Epstein studied mathematics and physics for his entire university career eventually earning a degree from the Imperial University of Moscow. He then went on to earn a Ph.D. at the Technical University of Munich in 1914 concentrating on a problem in the theory of diffraction of electromagnetic waves. However the outbreak of World War I rendered Epstein an enemy alien in Germany. Sommerfeld intervened on his behalf and he was allowed to stay as a private citizen and continue his research. In 1916 Epstein published an important paper explaining the Stark Effect using the Bohr-Sommerfeld quantum theory. After the war Epstein went to Leiden and worked as an assistant for Lorentz and Ehrenfest. In 1921Ñthe year this letter was writtenÑEpstein was recruited by Robert Millikan to join the physicists at the California Institute of Technology. Epstein accepted the position and stayed there for the rest of his career publishing extensively on quantum theory. Epstein was something of polymath and worked in numerous areas outside of quantum theory including work on air resistance the settling of gasses the theory of vibration and the absorption of sound. He was an avid supported of Freudian psychoanalysis including as one of the founding members of the Psychoanalytic Study Group that later merged with the Los Angeles Institute for Psychoanalysis. Epstein was also notably anti-communist and worried about the threat of nationalism.The areas of study mentioned in Einstein's letter of recommendation all came together to help form the science behind atomic and hydrogen bombs though neither Einstein nor Epstein anticipated quite where the science was headed in 1921. The letter mentions the Stark effect which is the shifting and splitting of spectral lines of atoms and molecules due to the presence of an external electric field. It is analogous to the Zeeman effect in which a magnetic field is the influence. The Rutherford-Bohr model presented in 1913 is a system consisting of a small dense nucleus surrounded by orbiting electronsÑsomewhat like the Solar System but with electrostatic forces instead of gravity. The Bohr model came to be recognized as a relatively primitive model of the hydrogen atom compared to the valence shell atom model. However because of its simplicity and the correct results it generates for certain systems it is still commonly used to introduce students to quantum mechanics.Overall this letter provides valuable insight into the scientific world during the height of Einstein's international career right when he first began traveling abroad and meeting fellow scientists internationally. The letter reflects Einstein's importance in the community and is a testament to Epstein's ability as a physicist. Original mailing creases. Fine condition. unknown

AN IMPORTANT SCIENTIFIC LETTER FROM EINSTEIN TO HIS CLOSEST MATHEMATICAL COLLABORATOR ACCOMPANIED BY A MANUSCRIPT LEAF OF CALCULATIONS IN EINSTEIN'S HAND ON THE SAME LINE OF RESEARCH. Although the original association of the letter and the leaf of calculations cannot be confirmed the two pieces clearly emerge from the same scientific context and have been preserved together. A superb pair from the final months of Einstein's German period. The Letter: In this intense and intellectually urgent letter Einstein writes to Walther Mayer his indispensable mathematical collaborator often referred to as "Einstein's Calculator" describing a newly conceived approach to the technical obstacles in their unified-field theory involving semi-vectors spinors and modified Dirac-type equations. Einstein tells Mayer he believes he "sees a new possibility" one that determines key constants in the system without resorting to the semi-vector construction. He then sketches the structure of the revised scheme points to the condition under which the full set of field equations reduces to a single one and warns that if this same collapse occurs in the general case "the whole thing would be useless." With his imminent departure from Germany he urges Mayer to examine the issue quickly and gives instructions for where a reply will reach him while en route. Dirac and De Broglie - Significance of the Scientific References: Of particular importance is Einstein's explicit engagement in this letter with the work of Paul Dirac and Louis de Broglie two of the central figures in early quantum theory. Einstein refers directly to the Dirac equations introduced only a few years earlier which provided a relativistic formulation of the electron and played a foundational role in quantum mechanics. He also invokes the De Broglie equations for matter waves reflecting his continued effort to reconcile quantum ideas with relativistic field theory. These references place the letter squarely at the intersection of Einstein's unified-field program and the emerging quantum framework he famously regarded with both fascination and skepticism. The letter thus documents Einstein actively testing whether concepts originating in quantum mechanics-Dirac's relativistic wave equation and De Broglie's wave-particle duality-could be absorbed into a geometrically unified classical field theory. Letters in which Einstein explicitly grapples with Dirac and De Broglie at this technical level are rare and represent an important record of his engagement with the central theoretical developments of the early twentieth century. Historical Context: Einstein's collaboration with Walther Mayer beginning around 1930 produced some of the most technically sophisticated papers of Einstein's later career. Together they developed new mathematical structures-semi-vectors spinors and higher-dimensional tangent-space formulations-used in their unified-field attempts. This letter dates from December 1932 only weeks before Einstein left Germany permanently and belongs to the final phase of their joint work published in the Sitzungsberichte of the Prussian Academy. Einstein valued Mayer so highly that he later persuaded the Institute for Advanced Study to create a permanent position for him the only such appointment ever granted for one of Einstein's collaborators. The Manuscript Calculations: Accompanying the letter is a two-page manuscript leaf containing Einstein's working calculations: trial expressions constraint conditions and variant formulations of the same type of semi-vector and spinor problems addressed in the letter. While we cannot confirm that these pages were originally enclosed with the letter they concern the same scientific material and have been preserved alongside it. Einstein manuscript leaves of this depth and technical significance-especially when tied to a known collaborative problem-are scarce. Significance: Whether or not originally sent together the letter and the calculations form a powerful and coherent scientific pair offering a rare view of Einstein actively working through equations testing ideas and relying on Mayer to verify mathematical structure. They capture Einstein at a critical inflection point in both his scientific life and personal circumstances as he prepared to leave Germany forever. --------- The letter from Einstein to Mayer reads in full translated from the original German: Dear Mr. Mayer! I believe I see a new possibility which promises success. It is along the lines of the recently devised way according to which one places zero on the right side of the Dirac-Equations. The novelty is in the fact that the constants a1 . a4 aside from a totally irrelevant factor are completely known without passing on to the specific Semi-Vectors. After omission of the _-terms the equations read Ee st ys = s 1 xe Or for De-Broglie-Equations of the restless particle E4 st ys = s 1a x4 Here is what's new: How does one choose the ay so that the De Broglie - Choices stay largely undetermined Result: The four equations 1a reduce themselves into a single one when and only when if one lets a1 = 1 a2 = 1 a3 = 1 a4 = 1 I believe that with this selection ay is for the equation describing the _-terms 1 the fitting substitute for the DeBroglie-Equation. These equations are already supplied by the simplest Hamilton function. See if the general equations 1 degenerate with this placing for a as well. If this were the case the whole thing would be useless. I leave on Saturday. A letter that is sent to Antwerp to the `Oakland' Hapag Antwerp harbor will reach me until December 13.

A remarkable working sheet showing Einstein making tensor formalism physically operational for continuum mechanics. Across three working zones the manuscript moves from a formal four-dimensional tensor transformation identity written in a distinct unidentified hand to Einstein's own derivations involving Volumenkraft Druckkraft stress force density diagrammatic testing and a heavily underlined mechanical equilibrium result. The folded rotated format gives the sheet the character of a compact notebook in miniature: formal tensor language brought into contact with physical terms local force relations diagrams and repeated calculation. The manuscript's all-lower-index notation explicit summations in Einstein's hand mixed coordinate idiom second-hand tensor identity and visible effort to make tensor language mechanically operational point most naturally to the 1912-1913 Zurich tensor period when Einstein was absorbing the post-Minkowski mathematics that General Relativity would require. Later revisitations cannot be entirely excluded but they explain the sheet less naturally.

EINSTEIN OFFERS STRONG AND PRESCIENT WORDS OF ENCOURAGEMENT TO THE LEADER OF THE NAACP IN THE FIGHT AGAINST RACIAL SEGREGATION AND DISCRIMINATION 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.

Translated from the original German: "No person has the moral right to call himself a Christian or Jew so long as he is prepared to engage in systematic murder at the command of an authority or allow himself to be used in any way in the service of war or the preparation for it." Beginning in 1925 the World League for Peace Ligue mondiale pour la paix under the direction of its president Georges Dejean solicited statements on peace from prominent scientists writers artists political leaders and other public figures throughout the world sending them large 11.5x16.5 inch sheets for their submissions. The resulting collection of more than 1000 original manuscripts was assembled between 1925 and 1932. A selection was reproduced in facsimile in the limited-edition volume Pax Mundi: Livre d'or de la paix published in Geneva by Paxunis in 1932. This is Einstein's original manuscript contribution to the project.
