"In 1907 Einstein published a paper entitled 'Theoretical Observations on the Brownian Motion' in which he considered the instantaneous velocity of a Brownian particle. Einstein showed that by measuring this quantity one could prove that 'the kinetic energy of the motion of the center of gravity of a particle is independent of the size and nature of the particle and independent of the nature of its environment.' This is one of the basic tenets of statistical mechanics known as the equipartition theorem. However Einstein concluded that due to the very rapid randomization of the motion the instantaneous velocity of a Brownian particle would be impossible to measure in practice.

Slight nick at bottom edge of lower wrap else better than very good. Includes the retort by Einstein and Rosen originators of speculation on the existence of "worm-holes" in spacetime to objections made to the general theory of relativity. According to Galina Weinstein: "Between 1935 and 1936 Einstein was occupied with the Schwarzschild solution and the singularity within it while working in Princeton on the unified field theory and with his assistant Nathan Rosen on the theory of the Einstein-Rosen bridges. He was also occupied with quantum theory. He believed that quantum theory was an incomplete representation of real things. Together with Rosen and Boris Podolsky he invented the EPR paradox. I demonstrate that the two-body problem in general relativity was a heuristic guide in Einstein's and collaborators' 1935 work on the Einstein-Rosen bridge and EPR paradox."

First printing of Einstein and Rosen's answer to Silberstein's critique of Einstein's Theory of Relativity ."Ludwik Silberstein who initially was a supporter of the special theory objected at different occasions against general relativity. In 1920 he argued that the deflection of light by the sun as observed by Arthur Eddington et al. 1919 is not necessarily a confirmation of general relativity but may also be explained by the Stokes-Planck theory of complete aether drag. However such models are in contradiction with the aberration of light and other experiments see "Alternative theories". And in 1935 Silberstein claimed to have found a contradiction in the Two-body problem in general relativity. However also this claim was refuted by Einstein and Rosen 1935 in the paper offered."Wikipedia. unknown
1952ref. 3091Princeton: np 1952. First edition. no binding. Very Good. EXTRAORDINARY EINSTEIN LETTER IN ENGLISH EXPLAINING SIMULTANEITY ONE OF THE CENTRAL TENETS OF RELATIVITY THEORY. Einstein's "1905 paper on special relativity is widely regarded as having destroyed the classical conceptions of absolute time and space along with absolute simultaneity and absolute length which had reigned in physics from the times of Galileo and Newton to the dawn of the twentieth century. The Special Theory teaches us that simultaneity is not as we supposed an absolute concept but is always relative to some inertial frame of reference. If we change the inertial frame of reference we change the events to be reckoned simultaneous." -Craig and Smith Einstein Relativity and Absolute Simultaneity The concept of simultaneity lies at the core of relativity theory. The very first sub-section of Einstein's legendary 1905 paper on Special Relativity is introduced by the title "Definition of Simultaneity" and "in the second paragraph of his 1905 relativity paper Einstein proved that simultaneity as defined in the first paragraph is a relative concept. This means as Einstein explained that 'we must not ascribe absolute meaning to the concept of simultaneity; instead two events that are simultaneous when observed from some particular coordinate system can no longer be considered simultaneous when observed from a system that is moving relative to that system.' In these words Einstein for the first time offered an explicit definition of what he means when he speaks of a relative concept. As we see it is a concept whose validity depends on the coordinate system chosen or in brief it is a frame-dependent concept. Simultaneity is no longer a binary relation depending also on the coordinate-frame involved. Furthermore Einstein's proof of the relativity of simultaneity in this paragraph is the first ever published rigorous proof of the relativity of a physical concept. The relativity of simultaneity became also the first major subject of dispute between proponents and opponents of the theory of relativity" Max Jammer Concepts of Simultaneity: From Antiquity to Einstein and Beyond. When Einstein expanded his relativity theory into his General Theory of 1916 the notion of simultaneity became less well-defined and more problematic and therefore much-debated. Einstein in the present letter is answering a question from Dr. Waldron Gardiner a physician apparently without any particular expertise in relativity theory about the concept of simultaneity in space the domain of general relativity. Dated July 10 1952 the letter reads in full: Dear Sir: "Your difficulty stems from the fact that you do not distinguish between general and special theory of relativity the latter being a limit case where you neglect gravitation. In the latter case there are special coordinate systems inertial systems and with respect to such system the concept of simultaneity has a sharp meaning and can be defined empirically by light signals. In general relativity the space and time coordinates have no direct physical meaning so that also the concept of simultaneity of spatially distant events has no physical meaning. Physical meaning can be attributed to this concept only in certain special cases which are characterized by certain symmetry qualities. Such case is not realized in nature. But in those idealizations which we use to represent expanding space there are coordinate systems representing space-time in the mathematically simplest form. With respect to such coordinate systems simultaneity has meaning but the definition of simultaneity as defined in special relativity theory is out of place here. Very sincerely yours SignedA. Einstein PrintedAlbert Einstein In short Einstein is explaining to Dr. Gardiner that since "space and time coordinates have no direct physical meaning" in cosmological terms i.e. there are no frames of reference that cover all of space his understanding of simultaneity in general relativity is flawed and based on the model of special relativity "a limit case" achieved only through a reductive and localized application of general relativity. Einstein concludes the letter with the provocative comment that in idealized systems representing expanding space simultaneity has meaning and in fact this "meaning" of simultaneity in general relativity has become a fertile area of exploration over the years see Jammer ibid.

1948ref. 3094Princeton: np 1948. first edition. Very Good. ONE OF EINSTEIN'S MOST DIRECT STATEMENTS ON GOD: A POWERFUL AND CONCISE PRECURSOR TO HIS CELEBRATED "GOD LETTER". In the letter dated September 25 1948 and addressed to the Indiana University student Barbara Homans Einstein writes: "I believe that the idea of a personal God is too anthropomrphic sic and childlike to be considered seriously. We have to content ourselves with that modest insight which is accessible to us." The letter is a strikingly concentrated statement of Einstein's religious philosophy. In two sentences he rejects the notion of an anthropomorphic personal deity while setting against it a characteristically modest view of human knowledge: rather than claiming access to metaphysical certainty "we have to content ourselves" with the limited understanding available to us. That formulation places the letter squarely within one of the most important recurring themes of Einstein's later correspondence: his distinction between conventional belief in a personal God and his own sense of awe before the rational order of the universe. Six years later in his famous letter to the philosopher Eric Gutkind of 3 January 1954 Einstein would return to the same subject in far greater detail describing the word "God" as an expression of human weakness and rejecting traditional religious conceptions with exceptional directness. Christie's described the Gutkind letter as Einstein's most fully articulated statement of his religious and philosophical views; it sold in 2018 for $2892500 at Christie's. The present letter is remarkable because the essential position of the later "God Letter" is already present here in distilled form. The shared target is the anthropomorphic personal God: a conception Einstein repeatedly rejected while maintaining that a profound sense of wonder before the structure of nature could still be called religious. It is a direct statement of Einstein's mature religious philosophy anticipating the central argument of the 1954 "God Letter" by more than five years. Typed letter signed "A.

An invitation written in Einstein's capacity as Chairman of the Trustees of the Committee to Lesser to attend a three day conference in Princeton the following month and asking him to be his special guest at a luncheon on the 17th of November. Einstein writes Lesser "as one who shares with American scientists a sense of the responsibility and urgency with which this great new force has impressed upon our lives ." and notes that one of the chief aims of the conference will be for "the scientists to reach final agreement on our program of education for survival ." Perhaps it was in his capacity as film producer that Lesser was considered a potential contributor beyond simple monetary help. The letter is addressed to Lesser at the Paramount Building 1501 Broadway NYC. Lesser 1890-1980 was a successful film producer a career that spanned the silent era up through such productions as THUNDER OVER MEXICO 1939 and OUR TOWN 1940 to the long string of post 1943 Tarzan films when he once again reacquired the rights after having produced the Buster Crabbe serial of 1933.

In a letter to his sister Maja Winteler-Einstein then resident in Switzerland dated December 1938 Einstein wrote "I am now working as some sort of itinerant relief committee and buckets of letters are coming in . I am helping the Ulm relatives with emigrating". Ursula Einstein born 1916 was able to get out; in 1940 she was a refugee in Port-au-Prince and later reached Brazil.

TOWARDS THE END OF HIS LIFE EINSTEIN WRITES TO ONE OF HIS FRIENDS FROM THE PATENT OFFICE CONCERNING ONE OF THE CENTRAL STRUGGLES OF HIS SCIENTIFIC LIFE. COMMENTING ON THE WORK OF DIRAC EINSTEIN ADMITS THAT ALTHOUGH HE "CAN'T TAKE A STATISTICAL FOUNDATION OF PHYSICS SERIOUSLY" HE FINDS IT "DIFFICULT TO MOVE BEYOND IT". Background: Einstein's struggle with accepting a strictly statistical quantum theory has been one of the most discussed and debated topics of twentieth-century physics. When introduced to the statistically-based quantum mechanics of Heisenberg Born and Jordan in 1926 Einstein famously wrote to Max Born that "Quantum mechanics is certainly imposing. But an inner voice tells me that it is not yet the real thing. The theory says a lot but does not really bring us any closer to the secret of the 'old one.' I at any rare am convinced that He is not playing at dice." Einstein letter to Born from 4 December 1926. From the onset "Einstein regarded the quantum theory as descriptively incomplete. What he meant was that in typical cases the probabilistic assertions provided by the theory for an individual quantum system do not exhaust all the relevant and true physical assertions about the system. Put briefly according to Einstein the typical statistical story told by quantum theory is not the whole story." Arthur Fine "What is Einstein's Statistical Interpretation or Is It Einstein for Whom Bell's Theorem Tolls". Einstein's discomfort with the new theory haunted him for the next three decades and his challenges to the theory were the cause of some of the most fertile and defining moments of modern science notably the celebrated "Bohr-Einstein debates" begun at the Fifth Solvay Conference 1927 and his monumentally influential "EPR" paper of 1935 "Can Quantum-Mechanical Description of Physical Reality Be Considered Complete" written with Boris Podolsky and Nathan Rosen. As late as 1949 in his "Reply to Criticisms" published in Albert Einstein: Philosopher-Scientist Einstein notes that Born and Wolfgang Pauli in their contributions to the volume "deprecate the fact that I reject the basic idea of contemporary statistical quantum theory insofar as I do not believe that this fundamental concept will provide a useful basis for the whole of physics" and spends the majority of the essay explaining his position and distinguishing between his acceptance of the model for "ensembles of systems" while still rejecting it for an "individual physical system". The letter: Dated September 12 1953 and written to his old colleague at the patent office in Bern Joseph Sauter the letter translated from the original German reads in full: Dear Mr. Sauter If I am able to I will gladly assist Mr. Keberle. I have heard of you often from my old friend Besso and I have also received a manuscript which deals critically with handwritten Dirac's presentation of the statistical approach to quantum theory. I have not been able to judge it myself because it is simply impossible for me to take a statistical foundation of physics seriously. But I have to admit that it is difficult to move beyond it. Yours sincerely signed A. Einstein. Albert Einstein. The recipient Joseph Sauter worked with Einstein at the Bern Patent office during the years he was developing the ideas for his revolutionary papers of 1905. "Among his colleagues at the Patent Office Einstein discovered one with similar scientific interests-Dr. Josef Sauter a French-Swiss who had also studied at the Polytechnic and who had been Professor Weber's chief assistant for a while. Sauter like Einstein tried to fill the gaps in the Polytechnic's syllabus by private study so that Einstein was able to discuss with him Maxwell's thermodynamics and Helmholtz's and Hertz's theoretical concepts. The two also discussed Einstein's publications on thermodynamics with the result that Sauter discovered a mistake in them which Einstein accepted 'without being the least upset.' Fifty years later Einstein recalled 'that I had a lot of discussions with Sauter about. my thermal-statistical papers'. At least as important as his help with the 'rewriting and amending' were Sauter's connections with scientific circles in Bern to which he soon introduced his new colleague." Albrecht Fölsing Albert Einstein. Edouard Keberle mentioned in the first line by Einstein was a Bulgarian physicist who at the time of the letter had just left the Institute of Theoretical Physics in Bern over a publication dispute. Not long after this letter - in early 1954 - Keberle accepted a post at the Midwest Research Institute in Kansas City. It is unclear if Einstein helped him in any way to get this position. Michele Besso - also mentioned in this letter - was Einstein's close lifelong friend. What prompts Einstein to declare that "it is simply impossible for me to take a statistical foundation of physics seriously" is the mention of a manuscript on the work of Paul Dirac. Philosophically Dirac was almost the opposite of Einstein - he had no interest in probing the interpretations of quantum theory wryly noting in his paper "The Inadequacies of Quantum Field Theory" that "The interpretation of quantum mechanics has been dealt with by many authors and I do not want to discuss it here. I want to deal with more fundamental things." It is revealing in this letter that although Einstein re-states his objection to a statistical basis of quantum theory he has doubts about his position admitting - less than two years before his death - that he still has difficulty moving beyond it.

1934ref. 1478Princeton: np 1934. 1st Edition. No Binding. Very Good. AN IMPORTANT SIGNED LETTER in English by Einstein revealing his reservations of associating with communism even in the fight against fascism. Written from Princeton NJ to Professor Albert Sprague Coolidge of Harvard University and dated February 16 1934 the letter reads: My dear Professor Coolidge: I had an opportunity of meeting personally Lord Marley and has sic very favorably impressed by his personality. It became known to me that he sympathizes with the Russian Government i.g. with the Russian communist party and that the committee for which he is active is influenced by communists. The problem as to the attitude which is advisable to be taken towards this committee is rather complicated. On the one hand the world-wide danger of fascism makes it necessary that all enemies of fascism cooperate; on the other hand an action which has communist leanings might endanger that fight since the important task undertaken in defense of culture and civilization may be linked up with interests of a political party. I myself have severed my connections with the committee which with my permission had used my name up to the end of last year. It seems to me advisable to take an attitude as follows: to help their action against fascism but not to identify oneself with the committee. Very truly yours signed A. Einstein P.S. I wish you would be good enough to use this strictly confidentially. In 1934 Lord Baron Marley Dudley Leigh Aman toured the United States to raise funds for his association the World Committee for the Victims of German Fascism. Marley through his committee was "passionately advocating a scheme for which he was to become an international figurehead - resettlement of oppressed German and Polish Jews in the Jewish Autonomous Region" in Siberia. He published a book "The Brown Book of the Hitler Terror and the Burning of the Reichstag sponsored by the World Committee and with an Introduction written by Lord Marley himself which was the first popular exposé of what was happening in Hitler's Germany. It documented the destruction of political parties trade unions and universities book-burning and the building of concentration camps. "At a fundraising dinner held in his honour in New York in February 1934 where Einstein presumably met him just before writing this letter Marley opened the Brown Book and 'speaking quietly declaring that he did not intend to harrow' read aloud to his audience of 600 American Jews some of the collected evidence of Nazi repressions. Here were documentary records of what was happening in Germany - a substantiation of the brutality that hitherto had had no distinct form in the mind of the American Jewish public. What before had been the subject of a growing fear mingled with disbelief was now being presented as hard fact and supported with detailed evidence. The New York Times 8 February 2005 reports the audience being 'startled' by the disclosures and the night ending with $3500 raised for the World Committee" The Jewish Quarterly No. 198. Einstein was correct to be suspicious of Marley's activities for it was later determined that the "World Committee" was indeed a Communist front; Einstein writing here to Coolidge in 1934 was prescient about the motives of the committee. This letter in addition to underscoring Einstein's passionate stance against fascism is particularly important as documentary evidence of Einstein's caution about having any dealings with communism especially considering that the U.S. FBI worried about Einstein's political leanings kept a file on Einstein that grew to 1427 pages.
