1931réf. 1403337Potsdam Germany 1931. Two letters by Albert Einstein. The first is a single-paged autograph letter signed by Albert Einstein with one horizontal fold and one vertical fold. In Very Good condition . Measuring 22.5 x 28.5 cm. Letter accompanied with mailing envelope both with matching paper-clip rust stain. Letter with some light wear along edges small staining to lower corner. Addressed to G. W. Meyer and dated 8 Oktober 31 in Potsdam the Letter reads in full: "Sehr geehrter Herr! Indem ich Ihnen für die Uebersendung des Buches von Henry George bestens danke sende ich Ihnen anliegend die gewünschte Meinungsäusserung mit der Bitte um Weiterleitung an Mrs. Evans. Mit ausgezeichneter Hochachtung" and signed in ink "A. Einstein". He thanks Meyer for serving as an intermediary in getting a book to him and for forwarding the enclosed letter. The second letter is a typed copy of Einstein's previously enclosed letter presumably made by Meyer before he passed the original on to Evans. Addressed to R. W. Evans and dated 8.10.1931 in Potsdam the letter discusses Henry George's economic theory of poverty and land nationalization compares it to Franz Oppenheimer's work and proposes questions to be asked. Presumably he was sent a copy of Henry George's Progress and Poverty. First published in 1879 it sparked the Progressive Era discussing the paradox of increasing inequality and poverty amid economic and technological progress as well as the economic value of land. Consignment. Shelved Case 3. The Letter reads in full: "Sehr geehrte Mrs. Evans! Ich habe das Buch von Henry George zum grössten Teil mit ausserordentlichem Interesse gelesen und glaube dass es in der Hauptsache einen unanfechtbaren Standpunkt vertritt insbesondere was die Ursache der Armut betrifft. Nie in diesem Buch vertretenen Ansichten stimmen soweit ich es beurteilen kann vollkommen mit den Resultaten des zeitgenössischen Professors Franz Oppenheimer überein der sie offenbar selbständig herausgefunden hat. Nicht einverstanden bin ich mit der Theorie des Zinses. Mit dem vorgeschlagenen Heilmittel der Verstaatlichung des Bodens und der Bodenschätzung scheint mir allerdings mehr ein Problem als eine Lösung gegeben zu sein. Soll z. Beispiel ein Boden Eigentum der Gemeinschaft das darauf hingestellte Haus aber Privateigentum sein Jedenfalls ist es schon von höchster Wichtigkeit dass das Wesen des Uebels klar aufgezeigt ist. Schon darum wäre es wichtig wenn das Buch die ihm gebührende Beachtung fände. Mit ausgezeichneter Hochachtung gez. A. Einstein." 1403337. Shelved Dupont Bookstore. 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.

1912réf. 3056np: np 1912. first edition. custom box. Very Good. ON THE ROAD TO RELATIVITY: A four-panel working bifolium from Einstein's early post-Minkowski tensor phase. 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. A rare survival documenting Einstein's working method on one of the foundational matter-side problems on the road to General Relativity. EINSTEIN ALBERT.
