‎Knowledge of Past and Future in Quantum Mechanics‎

‎Lancaster: Physical Review 1931. First Edition. Original wrappers. Fine. FIRST EDITION FIRST PRINTING IN ORIGINAL WRAPPERS of Einstein's paper outlining a thought experiment to suggest that the uncertainty principle requires the acknowledgement of an indeterminate past. "To Heisenberg at the 1920's only the prediction of the future was important and the mathematical theory assisted him to calculate the probability of the end-state given the initial state: the description of the intermediate development of the system between two objectively recorded or recordable states did not seem to correspond to physical reality. <br /> <br /> "On the other hand Einstein as a critic of quantum physics did not admit Heisenberg's standpoint especially that the indeterminacy principle does not refer to the past. In the paper 'Knowledge of Past and Future in Quantum Mechanics' 1931 Einstein proposed an imaginary experiment in which 'the possibility of describing the past path of one particle would lead to predictions as to the future behavior of a second particle of a kind not allowed in the quantum mechanics.' So Einstein concluded that 'the principle of the quantum mechanics must involve an indeterminacy in the description of past events which is analogous to the indeterminacy in the prediction of future events.'<br /> <br /> "This should be understood in the context of Einstein's argument against the 'completeness' of quantum physics just in the same way that the purpose of the EPR argument 1935 was to show that the 'completeness' of quantum physics would lead to absurdity. In other words Einstein did not positively assert the existence of indeterminate past events but only intended to deduce it as the necessary conclusion of the 'completeness' of quantum physics.<br /> <br /> "The problem of the 'indeterminate' past re-appeared about fifty years later in J. A. Wheeler's discussion of the 'delayed-choice' experiment. This experiment is not an imaginary but an actual one which uses one particle say photon instead of two particles in Einstein's case.<br /> <br /> "After confirming the fact that what we can say of past events is decided by delayed choices made in the near past and now Wheeler discusses the possibility that the phenomena called into being by the present decision can reach backward in time even to the earliest days of the universe. He says:<br /> <br /> 'To use other language we are dealing with an elementary act of creation. It reaches into the present from billions of years in the past. It is wrong to think of the past as "already existing" in all detail. The "past" is theory. The past has no existence except as it is recorded in the present. By deciding what questions our quantum registering equipment shall put in the present we have an undeniable choice in what we have the right to say about the past.'<br /> <br /> "The interpretation of the indeterminacy principle will be altered if we accept the concept of the past indeterminacy. Heisenberg originally considered this principle as the limit of the exactitude of two incommensurable quantities at the simultaneous measurement. But the indeterminacy of past events which have not been recorded have a connection not with their simultaneous measurability but rather with the definability of their historic routes. That the definition of the past route or history of a particle depends on the present choice of an experimenter is the meaning of the 'indeterminate past'" Yutaka Tanaka "The 'Individuality of a Quantum Event".

‎Autograph Letter Signed ALS Denouncing Racial Segregation‎

‎Princeton NJ: np 1943. First edition. nb. Fine. EINSTEIN OFFERS STRONG AND PRESCIENT WORDS OF ENCOURAGEMENT TO THE LEADER OF THE NAACP IN THE FIGHT AGAINST RACISM AND SEGREGATION 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.

‎Typed Letter Signed‎

‎Typed Letter Signed and Annotated by Einstein Discussing Quantum Theory and the Principle of General Relativity EINSTEIN Albert 1879-1955. Typed letter signed "A. Einstein" to Mr. Daniel M Lipkin. Princeton New Jersey July 5th 1952. 1 page Quarto 11 x 8 1/2 inches; 279 x 217 mm. On stationary for the Institute for Advanced Study School of Mathematics. As well as the signature the letter contains a few ink notations including an equation. Also with the corresponding transmittal envelope. With one horizontal middle crease and two vertical creases as expected with a letter. Overall about fine. This 1952 typed letter signed and annotated by Einstein is to Daniel Lipkin an engineer and a former student of his friend David Bohm at Princeton regarding some equations he had sent to Einstein for comment. Einstein discusses that he has reason to belive that the "present quantum theory inspite sic of it's many successes is far from the truth." "Mr. Daniel M. Lipkin 4925 Rubicam Str. Philadelphia 44 Pa. Dear Mr. Lipkin: It is of course an obstacle for the testing of the theory that it is practically impossible to operate with the solution of the equations g i k. l § 0 -1 with respect to the T. Your point of view to try to operate on the basis of certain lines analogous to the geodetical line seem to me not appropriate for reasons of principles. A relativistic theory of the total field should according to my opinion cannot admit singularities. Particles concentrated in a point can therefore not be used in such theory. For this reason I do not believe that any lines should play a fundamental role. The conviction that only solutions without any singularities can claim physical meaning creates a tremendous difficulty because there are for non-linear differential equationsóas far as I knowóno methods to find them out systematically or even to find general theorems. I too have many reasons to believe that the present quantum theory inspite sic of its many successes is far from the truth. This theory reminds me a little of the system of delusion of an exceedingly intelligent paranoiac concocted of incoherent elements of thought. As you also seem to believe I believe it impossible to get a real insight without satisfying from the start the principle of general relativity. I feel however by no means sure that my own approach is the right one. I do also not believe that the de Broglie-Bohm's approach is very hopeful. It leads f.i. to the consequence that a particle belonging to a standing wave has no speed. This is contrary to the well-founded conviction that a nearly free particle should approximately behave according to classical mechanics. Sincerely yours A. Einstein Albert Einstein" "Daniel Lipkin a Bronx New York native who as a self-described "awestruck 15 year-old high school student" first wrote to Einstein in 1944 and continued his correspondence with the physicist after completing his studies at Princeton 1946-1949 under Einstein's friend David Bohm. Lipkin went on to work as an electrical engineer working for Sperry Univac designing early computers and later at American Electronic Laboratories.

‎Strahlungs-Emission und -Absorption nach der Quantentheorie Emission and Absorption of Radiation in Quantum Theory‎

‎Braunschweig: 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. 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.

‎Portrait Photograph of Albert Einstein signed by Yousuf Karsh‎

‎Princeton NJ: np 1948. framed. Fine. ONE OF THE MOST CELEBRATED IMAGES OF EINSTEIN SIGNED BY MASTER PHOTOGRAPHER YOUSUF KARSH. On February 11 1948 Yousuf Karsh perhaps the most accomplished portrait photographer of his generation visited The Institute for Advanced Study in Princeton to fulfill a dream of his: to photograph Albert Einstein. As he later explained: "Among the tasks that life as a photographer had set me a portrait of Albert Einstein had always seemed a 'must' - not only because this greatest refugee of our century has been accounted by all the world as the most outstanding scientist since Newton but because his face in all its rough grandeur invited and challenged the camera." Karsh: Beyond the Camera David Travis ed. "At Princeton's Institute for Advanced Study I found Einstein a simple kindly almost childlike man too great for any of the postures of eminence. One did not have to understand his science to feel the power of his mind or the force of his personality" official Karsh website. "Awed before this unique intellect I yet ventured to ask Einstein his views on human immortality. He mused for a moment and then replied 'What I believe of immortality There are two kinds. The first lives in the imagination of people and is thus an illusion. There is a relative immortality which may conserve the memory of an individual for some generations. But there is only one true immortality on a cosmic scale ant that is the immortality of the cosmos itself. There is no other.' "He spoke of these ultimate mysteries as calmly as he might a student's question about mathematics - with such an air of quiet confidence indeed that I found his answer profoundly disturbing to one who held other views. Knowing him to be an accomplished violinist I turned the conversation and asked if there were any connection between music and mathematics. 'In art he said 'and in the higher ranges of science there is a feeling of harmony which underlies all endeavour. There is no true greatness in art or science without that sense of harmony. He who lacks it can never be more than a great technician in either field.' "Was he optimistic about the future harmony of mankind itself He appeared to ponder deeply and remarked in graver tones: 'Optimistic No. But if mankind fails to find a harmonious solution than there will be disaster on a dimension beyond anyone's imagination.' To what source should we look for the hope of the world's future 'To ourselves' said Einstein. He spoke sadly yet serenely as one who had looked into the universe far past mankind's small affairs. In this humor my camera caught him. the portrait of a man who had traveled beyond hope or despair." Yousuf Karsh Regarding Heroes. Opening quote from: Colin Naylor ed. Contemporary Photographers.

‎EINSTEIN ALBERT; HALSMAN PHILIPPE‎

‎Albert Einstein: Silver Gelatin Print Photograph‎

‎Princeton NJ: Halsman 1947. Photograph. Fine. ONE OF THE MOST FAMOUS IMAGES OF EINSTEIN. Philippe Halsman's now iconic 1947 photograph of Einstein has become not only one of the most celebrated images of Einstein but one of the most recognizable images of the twentieth century. It was used to a 1966 US postage stamp of Einstein and was featured on the cover of Time Magazine honoring Einstein as the "Person of the Century".&#8232;&#8232; The photographer Halsman in his book Philippe Halsman: A Retrospective explained the circumstances of the photo: I admired Albert Einstein more than anyone I ever photographed not only as the genius who single-handedly had changed the foundation of modern physics but even more as a rare and idealistic human being.&#8232; Personally I owed him an immense debt of gratitude. After the fall of France it was through his personal intervention that my name was added to the list of artists and scientists who in danger of being captured by the Nazis were given emergency visas to the United States.&#8232; After my miraculous rescue I went to Princeton to thank Einstein and I remember vividly my first impression. Instead of a frail scientist I saw a deep-chested man with a resonant voice and a hearty laugh.&#8232; The question of how to capture the essence of such a man in a portrait filled me with apprehension. Finally in 1947 I had the courage to bring on one of my visits my Halsman camera and a few floodlights. After tea I asked for permission to set up my lights in Einstein's study. The professor sat down and started peacefully working on his mathematical calculations. I took a few pictures. Ordinarily Einstein did not like photographers whom he called Lichtaffen light monkeys. But he cooperated because I was his guest and after all he had helped save me.&#8232; Suddenly looking into my camera he started talking. He spoke about his despair that his formula E=mc2 and his letter to President Roosevelt had made the atomic bomb possible that his scientific search had resulted in the death of so many human beings. "Have you read" he asked "that powerful voices in the United States are demanding that the bomb be dropped on Russia now before the Russians have time to perfect their own" With my entire being I felt how much this infinitely good and compassionate man was suffering from the knowledge that he had helped to put in the hands of politicians a monstrous weapon of devastation and death.&#8232; He grew silent. His eyes had a look of immense sadness. There was a question and a reproach in them.&#8232; The spell of this moment almost paralyzed me. Then with an effort I released the shutter of my camera. Einstein looked up and I asked him "So you don't believe that there will ever be peace"&#8232; "No" he answered. "As long as there will be man there will be wars." Silver prints of this photograph have been printed in different sizes over the years.

"In a companion paper to "On a Heuristic Point." published in 1906 Einstein exposed appeal to the quantum as fundamentally counter to the ethos of classical physics: 'the theoretical bases on which Planck's radiation theory rests are different from those of Maxwell's theory'. Planck had not initially intended to quantify light-radiation itself but Einstein demonstrated that his own 'light-quantum hypothesis' was implicit in Planck's earlier work.

‎Photographs and Letters March-April 1932‎

‎np: np 1932. First edition. nb. UNPUBLISHED CANDID PHOTOGRAPHS OF EINSTEIN AND LETTERS BY WILLIAM HUBBARD OFFERING AN INTIMATE VIEW OF THE SCIENTIST ON VACATION. On March 2 1932 at the height of his career and world fame Albert Einstein and his wife Elsa set off on a vacation to their German homeland departing from Los Angeles on the M. S. San Francisco. Another passenger aboard the ship was the renowned music scholar William Lines Hubbard. Famous in his own right Hubbard was the music critic for the Chicago Tribune and author of a definitive 11-volume work on the history of opera published 1908.  Accompanying Hubbard was his companion Julia Reid their cabins adjacent to that of the Einstein's. As was the practice during this era Hubbard kept detailed journals and letters of his travel experiences.  This collection from the estate of Hubbard contains the following items:&#8232; 1. Three unpublished small black-and-white and sepia photographs.  The first photograph 4.5" x 2.5" pictures Einstein his wife Elsa the Ship's Captain Hubbard the tall figure and three other of the ship's passengers dated 3/14/32.  The second photograph 3.5" x 3.25" is an outstanding full front image of Einstein his wife Elsa and the ship's Captain. The final photograph 4.5" x 2.5" is a full frontal image of Einstein and his wife Elsa both seated in deck chairs with the ship's Captain standing behind.&#8232; 2. Typed letter dated March 22 1932 written while sailing through the South Atlantic. Six pages typed front and back on two pieces folded of the ship's original stationary approx. 7.5x11 in. Excerpts on Einstein include:&#8232;&#8232; Of our Six Passengers two are Prof. Einstein and wife. They are proving very delightful companions-- sincere unaffected and jolly. At first they were very reserved and merely bowed and smiled and "Guten-Morgan-ed" when entering and leaving the dining room but when they had become rested and saw that none of the rest of us planned to intrude they came forward and have been very genial. She is a great talker but talks interestingly. He walks deck smoking his stubby black pipe or whistling cheerily his gray hair blowing in the breeze. Each forenoon and sometimes in the afternoon he goes to the piano and plays for half hour or so. Plays in that satisfying manner peculiar to a man to whom music is a comfort and who thinks musically. It is in no wise brilliant playing but it is throughly enjoyable to hear. The rest of the time he sits in his steamer chair or in his cabin reading or thinking. On the 14th he had his 53rd birthday and the Capt had ordered from La Libertad Salvador where we had taken cargo the day before large bunches of easter and tiger lilies which in the morning were on the Einstein table together with a birthday cake the ship's cook had made and countless cards and letters which friends had sent. It was all a complete surprise to them both and their happiness was childlike in its spontaneity and sincerity. It was heart warming to watch them. They seem to appreciate being left to themselves and not being lionized. It is the third time they have come through the canal on these boards an they enjoy it to the full.&#8232; 3. Typed letter dated April 1 1932 written while entering the English Channel. Seven pages on two approx. 8.5x11in sheets folded of the ship's original stationary.  Excerpts on Einstein include: &#8232;&#8232;We had good fun watching for crocodiles along the banks as we came up the cut and Prof Einstein was especially gleeful when he discovered one. Professor Einstein loves the roung sic weather and has reveled in it. He and the Mme are proving very delightful fellow passengers. She is very chatty but chats interestingly and he struts up and down deck smoking his stubby pipe or whistling like a jolly kid his white hair blowing in the breeze. We have some talks occasionally and he yesterday when he saw the copy of Living Philosophies which I had given me sic before I left San Diego and in which his article is the first took the book and autographed his picture and wrote in remembrance of the happy days on board the San Francisco. I don't think I told you of his birthday which occurred on the 14 of March the day before we reached the Canal. The Capt came to know if it and when the Einsteins came to their table at breakfast they found it decorated with three huge vases of Easter and Tiger lilies which the Capt had secured in La Libertad. The cook had made a gorgeously decorated Torte-- one of the filled and frosted German cakes-- and there were letters and telegrams from friends which had been sent in the Capt's care. It was a complete surprise to the Einsteins and they were like two happy kiddies. It was gladdening to watch their simple and keen enjoyment. Later we had pieces of the Torte which were a bit of muchness for breakfast but which of course we ate. &#8232;4. Typed letter dated April 24 1932 written in Merano Italy.

He was a huge and tremendously rotund gent wearing a soft felt hat and a short overcoat the buttons of which seemed fated to "bust off" at any moment. His chief employment seemed to be running about from side to side of the dock into the warehouse and out again clambering onboard and then clambering off and all the time shouting orders at the top of his voice and gesticulating wildly. Einstein had been reading the "Living Philosophies" which I had loaned him and was especially curious concerning Mencken and how he happened to be included in the great ones in the book. I gave him an outline of Mr. M's greatness and assured him that the book cold sic well largely on account of M being included.  All of which amused the Einsteins greatly.  So when this wild boss hove into sight that morning and began his excited directing Mrs E said "there is Mister Mencken" and thus he remained so long as we were in Rotterdam. The Einsteins were starting early the next morning for Berlin so they went about 9 pm to the custom house and had their 16 packages bundles and gifts examined.  Frau Professor had a funny story to tell of their experience with the 150 pound bag of coffee that had been presented them in Salvador. &#8232;&#8232;&#8232;5.

‎Zur allgemeinen Relativitatstheorie On the General Theory of Relativity‎

‎Berlin: Verlag der Königlichen Akademie der Wissenschaften 1915. First edition. Original wrappers. Fine. FIRST PRINTING IN ORIGINAL WRAPPERS IN FINE CONDITION of Einstein's famous November 4 1915 paper introducing his new version of general relativity. By autumn 1915 Einstein experienced a "crisis" in his work on his gravitational equations and the general theory of relativity forcing him to abandon several key elements of his earlier work. In October 1915 "Einstein shifted his focus from the physical strategy which emphasized his feel for the basic principles of physics and returned to a greater reliance on a mathematical strategy which made use of the Riemann and Ricci tensors. 'Einstein's reversal' writes John Norton 'parted the waters and led him from bondage into the promised land of general relativity'. "The result was an exhausting four-week frenzy during which Einstein wrestled with a succession of tensors equations corrections and updates that he rushed to the Prussian Academy in a flurry of four Thursday lectures. It climaxed with the triumphant revision of Newton's universe at the end of November 1915" Isaacson. In this November 4th paper and lecture On the General Theory of Relativity Einstein presented "to the plenary session of the Prussian Academy a new version of general relativity" explaining "that he had 'completely lost confidence' in the equations he proposed in October 1914. His answers were still not entirely right. There was still one flaw a much smaller one which he eliminated three weeks later. But the road lay open. He was lyrical. 'No one who has really grasped it can escape the magic of this new theory'" Pais. Three weeks later - on November 25 1915 - Einstein did indeed eliminate the flaw and "presented to the physics-mathematics section of the Prussian Academy of Sciences a paper in which 'finally the general theory of relativity is closed as a logical structure'. The work is done" Pais. See: Isaacson Einstein pp. 211-221 and Pais Subtle is the Lord pp.250-261. Note: Einstein's November 11 paper was titled "Zur allgemeinen Relativitatstheorie II" but rather than a continuation or advancement of the November 4 paper it was a step backwards introducing a serious mistake that he would correct by November 25.

‎EINSTEIN ALBERT‎

‎Die formale Grundlage der allgemeinen Relativitätstheorie. The Formal Foundation of the General Theory of Relativity‎

‎Berlin: Königlichen Akademie der Wissenschaften 1914. FIRST EDITION OFFPRINT. Original wrappers. Fine. FIRST EDITION COMMERCIAL OFFPRINT ISSUE of Einstein's important 1914 paper on the development of general relativity. "In summer 1914 Einstein felt that the new theory general relativity should be presented in a comprehensive review. He also felt that a mathematical derivation of the field equations that would determine them uniquely was still missing. "Both tasks are addressed in a long paper presented in October 1914 to the Prussian Academy for publication in its Sitzungsberichte. It is entitled 'The formal foundation of the general theory of relativity'; here for the first time Einstein gave the new theory of relativity the epithet 'general' in lieu of the more cautious 'generalized' that he had used for the Entwurf" Landmark Writings in Western Mathematics 1640-1940. "According to John Norton 'How Einstein Found His Field Equations' this major review article was intended to convey the full content of the 1913 'Entwurf' theory: 'The principal novelty lies in the mathematical formulation of the theory. Drawing on earlier work with Marcel Grossman Einstein formulated his gravitational field equations using a variation principle. Using this richer mathematical structure Einstein offered a proof purporting to demonstrate that his theory had the maximum covariance compatible with the hole argument; that is covariance under 'justified' transformation between the 'adapted coordinate systems' he had introduced with Grossman'" Calaprice The Einstein Almanac.
