1941réf. 2142520/12/1941. Brigitte Kaufmann was born in Germany but when the Nazis came to power in 1933 she fled to Paris. In France Kaufmann worked as an actress under the name of Brigitte Châtel and translated documents. She met her future husband Alfred Alexander-Katz in Paris and they married in 1939; the following day her husband was taken to an internment camp. He was given the choice of being interned in a labor camp or joining the Foreign Legion and chose the latter. Alexander was then sent to Clermont in Vichy France and the family relocated there. Dr. Walter Rudlin was a social science professor at Sarah Lawrence College in New York and actively involved in anti-fascist activities. He was the author of “The Growth of Fascism in Great Britain”. In September 1942 he left his position and joined the U.S. Board of Economic Welfare whose chair was Vice President Henry Wallace. His wife Eryl was interested in bringing Jews in Europe out of harm’s way and she knew the Alexander-Katz family. So Eryl sought to get Brigitte and her family safely out of Europe to Mexico and sought Einstein’s help. On March 12 1941 Einstein responded noting that Brigitte is his relative. “Thank you very much for your letter of March 11th. I am very gratified indeed to learn that our mutual friends Fred and Brigitte Alexander-Katz have some prospect to receive a visa into Mexico. I am certainly willing to vouch for their reliability and integrity both personal and political. I have known Mrs. Brigitte Alexander-Katz - whose family is related to mine - since she was a little girl. Her husband a very able engineer will certainly be useful to any country which receives him. If you will send me the address of the proper Mexican authority I shall gladly send any letter of recommendation desired.” This was a warm letter indeed expressing true concern and friendship for the Alexander-Katz family. On April 3 1941 Einstein again wrote Rudlin noting “Enclosed I am sending you the requested letters in the hope that they may be successful.” But there were delays and no visa so Rudlin wrote Einstein seven months later asking him to take the matter up with the Mexican government. Typed letter signed on his blind-embossed letterhead Princeton December 20 1941 to Mrs. Eryl Rudlin saying that he expects the visa to be granted but does not feel he ought to approach the Mexican government directly. “The Mexican authorities know that I am interested in the case of the Alexander-Katz family; they have kept me informed about the whole development of the matter. I have no doubt that admission to Mexico will be granted as it has been granted to hundreds of people in the same situation. I can give Mr. Alexander-Katz a recommendation but it is out of the question that I ask the Minister of Education to send him an official invitation. I have already done what could be done without intrusion.” Despite what he writes here to calm Mrs. Rudlin Einstein might have exerted some gentle pressure on Mexico by contacting the Mexican ambassador to the U.S. Gilberto Bosques; or the Alexander-Katz visas may have already being granted at that moment. The Einstein Archives is silent on this subject. But soon after Einstein soon wrote this letter in 1942 a telegram to the young Alexander-Katz family arrived stating that Einstein and Rudolph Uhlman a lawyer in New York had secured visas through Ambassador Bosques for them to escape to Veracruz Mexico aboard the ship San Thomé. In Mexico Brigitte she became a noted author actress director and translator. She became the first woman in Mexico to produce and direct television programs. Speaking five languages she also worked as a translator for UNESCO and Amnesty International. Her daughter Susana and granddaughter Sophie also became actors. unknown books
réf. 184029/9/54. The fullest summation we have seen by Einstein comparing relativity to Newtonian concepts of space and time Immanuel Kant took both Euclidean geometry and the Newtonian laws of motion to be synthetic a priori principles which from Kant’s point of view function as necessary presuppositions for applying our fundamental concepts of space time matter and motion to our sensible experience of the natural world meaning they are fixed necessary conditions. This idea rested on the absolute nature of space and time the work of Newton and the relationship between geometry and physics. In 1905 while a young patent clerk and physicist in Bern Switzerland Albert Einstein obtained his doctorate and published a paper that explained his newly developed Special Theory of Relativity. This unlocked many mysteries of the universe and introduced the world to ""e=mc2"" equating mass and the speed of light with energy. It established that time and space are not fixed and in fact change to maintain a constant speed of light regardless of the relative motions of sources and observers. Just 10 years later in 1915 Einstein published his General Theory of Relativity which described the universe as a four-dimensional continuum with time added as the fourth dimension where gravitational effects are explained by the warping of space-time. In this theory Einstein incorporated gravity as a geometric property of space-time. The impact of Einstein's work between 1905 and 1915 challenged many principles of physics that had been accepted for centuries. In 1921 he won the Nobel Prize for his work. Time Magazine named him the Person of the Century for the 20th century for his discoveries in relativity and space-time. Einstein is the most important scientist since Isaac Newton and probably the most famous in history. Space and time were considered relativistic more subjective and not the fixed a priori notions that had long permeated the mathematical and scientific worlds. Max Fischler was a California scientist who was interested in the implications of this distinction: were space and time now to be studied together in this context only or were the nature of space and the nature of time different In special relativity what appears simultaneous to one person might not to another - they are relative. You cannot separate space and time; they occur subjectively and semi-dependently but are not tied to the content of that space. With General Relativity space-time remains but matter warps it. It's a field like the sheet of a trampoline but reacts to matter. One needs all four dimensions of space-time and without them the others don't exist. You need matter for space. On September 5 1954 he wrote to Einstein: "".Can anything in your theory of Relativity be said to throw new light on the nature of space and time themselves Or must we rest satisfied with the purely new logical treatment of these conceptions In other words does the new view of space and time as space-time carry any new meaning ontologically beyond the purely mathematical and logical relationship between the two. Or to put it differently: When Minkowski in his famous words said 'Space by itself and time by itself must not sink into the mere shadows and only a kind of union of the two can preserve an independent existence' did he not attach some new real meaning to the 'spacetime' which the old independent notions of space and time could not convey If so in what does this new meaning consist."" Four days later Einstein replied in this letter: Typed letter signed in German on his personal blind embossed letterhead Princeton September 9 1954 to Max Fishler. ""The expression cited in the second paragraph only signifies the wish for logical clarity in the formal expressions. De facto the justification for concepts lies in their ability to comprehend the empirically given. ""In classical mechanics space and time were completed existences which had to be presupposed as real a priori in order to give meaning to the laws of motion. It was a reality in the same sense as the reality of matter; even governing the latter. In this sense Kant was entirely wrong. ""The case was the same as regards the Special Theory of Relativity only that an objective separation of space and time was abandoned in the sense that there could no longer be any objective simultaneity. Here too the four dimensional space is a reality independently of the physical content of space. ""Regarding the General Theory of Relativity however this is principally different. What we call ""space"" is here only an extension of a Field dimensionality hence no longer independent of the content of space. It is real in the same sense as matter but has no real existence independently of matter. When the field is taken away there does not remain any space but just nothing.” Letters of Einstein directly relating to relativity are increasingly uncommon and this is one of the finest such letters we have had. unknown books
1702réf. 1536217/02/1953. In this letter from Einstein to David Bohm Einstein discusses the importance of connecting a key principle of the relatively new theory of quantum mechanics the “Born interpretation” to physical quantities that can be measured in the real world. To him it is essential that mathematical theories be connected to measurable quantities. In this letter Einstein’s uneasiness with quantum mechanics is apparent saying that validation of the seemingly random quantum mechanics “…can only be done on the basis of classical mechanics.” Without this validation quantum theory has essentially “no controllable meaning.” <img class=""alignnone wp-image-22637 size-post-window"" src=""https://cdn.raabcollection.com/wp-content/uploads/20231204163327/Einstein-born-2-e1639117238988-1600x656.jpg"" alt="""" width=""1600"" height=""656"" /> Max Born was a renowned physicist who was crucial for the development of quantum mechanics and also the Ph.D. supervisor of many important physicists including J. Robert Oppenheimer. Quantum mechanics describes the weird behavior of tiny subatomic particles. It’s also the guiding theory that led to critical technologies like nuclear power MRI machines and transistors in computers and phones. One of Born’s biggest contributions to quantum mechanics was the interpretation of the probability density which is a mathematical operation performed on the “psi-function” in Einstein’s words to predict the most probable physical quantities of a quantum particle. Einstein believed that probabilities only make sense if you can determine the values that they predict independently by measurement. This is easy to do in classical Newtonian mechanics the physics of big things in everyday life. But Einstein said we can’t measure it for something like a “bound electron” i.e. an electron in an atom. In order to interpret Born’s probability density function you need to connect the mathematics to real values. Einstein’s correspondence with Born on this subject is published and famous. To Einstein the universe is observable and measurable. When confronted with one of the principle tenets of Quantum Mechanics Einstein remarked now famously “Quantum mechanics is very imposing. But an inner voice tells me that it is not the real McCoy. The theory delivers a lot but hardly brings us closer to the secret of the Old One God. I for one am convinced that He does not throw dice.” This statement was made in one of those significant letters to Born. What he meant here is that rules of science cannot be random and in the rolling of dice we would have to accept unknown variables and therefore be unable to predict precisely via objective measurements. Therefore in Quantum Mechanics as in gambling an uncertainty of measurement exists. And to Einstein the universe is observable and measurable. He did not object to Quantum Mechanics per se; indeed he made notable contributions. But he eschewed any reliance on what was not observable and knowable. <img class=""alignnone wp-image-22634 size-post-window"" src=""https://cdn.raabcollection.com/wp-content/uploads/20231204163356/Einstein-born-5-e1639117103621-1600x616.jpg"" alt="""" width=""1600"" height=""616"" /> David Joseph Bohm was an American scientist who has been described as one of the most significant theoretical physicists of the 20th century and who contributed unorthodox ideas to quantum theory neuropsychology and the philosophy of mind. His first book Quantum Theory published in 1951 was well received by Einstein among others. But Bohm became dissatisfied with the orthodox interpretation of quantum theory he had written about in that book.Bohm’s aim was not to set out a deterministic mechanical viewpoint but to show that it was possible to attribute properties to an underlying reality in contrast to the conventional approach. He began to develop his own interpretation the De Broglie–Bohm theory also called the Pilot wave theory the predictions of which agreed perfectly with the non-deterministic quantum theory. He initially referred to his approach as a hidden variable theory. Bohm originally hoped that hidden variables could provide a local causal objective description that would resolve or eliminate many of the paradoxes of Quantum Mechanics the measurement problem and the collapse of the wavefunction. However Bell’s theorem complicates this hope as it demonstrates that there can be no local hidden variable theory that is compatible with the predictions of Quantum Mechanics. The Bohmian interpretation is causal but not local. Albert Einstein who had suggested that Bohm search for a realist alternative to the prevailing Copenhagen approach did not consider Bohm’s interpretation to be a satisfactory answer to the quantum question. The Copenhagen interpretation is an expression of the meaning of Quantum Mechanics that was largely devised in the years 1925 to 1927 by Niels Bohr and Werner Heisenberg. It remains one of the most commonly taught interpretations of Quantum Mechanics. According to the Copenhagen interpretation physical systems generally do not have definite properties prior to being measured and Quantum Mechanics can only predict the probabilities that measurements will produce certain results. The act of measurement affects the system causing the set of probabilities to reduce to only one of the possible values immediately after the measurement. In classical mechanics a particle has at every moment an exact position and an exact momentum. These values change deterministically as the particle moves according to Newton’s laws. Under the Copenhagen interpretation of Quantum Mechanics particles do not have exactly determined properties and when they are measured the result is randomly drawn from a probability distribution. The Schrödinger equation predicts what the probability distributions are but fundamentally cannot predict the exact result of each measurement. <img class=""alignnone wp-image-22633 size-post-window"" src=""https://cdn.raabcollection.com/wp-content/uploads/20231204163406/Einstein-born-e1639117155596-1600x360.jpg"" alt="""" width=""1600"" height=""360"" /> Typed letter signed on his blind embossed letterhead February 17 1953 Professor Bohm. “Dear Bohm: I thank you very much for the prompt reaction to my little article. I did of course not expect that you would agree with me. For scarcely anyone is inclined to abandon an enterprise in which le has invested a great deal of work. “I do not want to answer your letter in detail although it deserves it very much. Only a short remark concerning the interpretation of Born’s standpoint: “According to Born the physical meaning of the psi-function follows: it determines probabilities f.i. for the value of impulses. this makes sense only if the impulse is defined independently of the mathematical theory by some feasible measurement. This can only be done on the basis of classical mechanics. F.i. if one has calculated the impulse of a bound electron on the basis of a psi-function then this result has no controllable meaning. For there is no possibility to measure such a thing not even approximately. However if one has to do with a makro-object which is at least temporarily approximately free then one is able to determine experimentally at least approximately its impulsef.i. through two successive snapshots or through radar. If it is at all possible to attribute meaning to Born’s interpretation then the impulse the probability of which appears in the theory has to be put equal to the impulse thus measured. Classical approxi_mate measurement of the impulse is however in my example very well feasible without first removing the walls and then waiting some time. Born’s probability therefore has to be interpreted as relative to the impulse thus measured if this probability is to have any meaning at all. “The vanishing of position-probability for the nodes offers no difficulty though it is true that this fact excludes the interpretation of the process as a motion in the strict sense of the word. For the factual process will only approximately be describable as a motion as f.i. the action of a gas upon a small part of the wall is describable only approximately by the concept of pressure. “With regard to the publication of your remarks in the Born volume I have some scruples the reason for which you will readily understand. I have sent a copy of my article to you but not to de Broglie because this would have seemed to me somewhat pretentious. If therefore your answer would be published together with my remarks without de Broglie having had the possibility to do the same he might feel it as an unkindness from my side. “This would be avoided if you would send De Broglie my remarks together with your reply adding that you do this with my consent. If you have done this and have received his reaction to it – then the editors of the Born volume can be approached in the matter. I would consider it as reasonable and justified to do so.” <img class=""alignnone wp-image-22636 size-post-window"" src=""https://cdn.raabcollection.com/wp-content/uploads/20231204163341/Einstein-born-3-1-e1639117201589-1600x672.jpg"" alt="""" width=""1600"" height=""672"" /> This is a remarkably detailed scientific letter mentioning numerous significant physicists containing a hand-drawn symbol and directly relating to his important theories.

Flechtheim appeared in the art world shortly after 1900 with a collection of paintings by Vincent van Gogh and Paul Cézanne; French Avant garde early works of Pablo Picasso Georges Braque and André Derain; paintings of Wassily Kandinsky Maurice de Vlaminck Alexej von Jawlensky Gabriele Münter and the Rhein Expressionists Heinrich Campendonk August Macke Heinrich Nauen de and Paul Adolf Seehaus de. Flechtheim opened his first gallery in Düsseldorf in 1913 followed by galleries in Berlin Frankfurt Cologne and Vienna. Flechtheim served in the German Army during World War I but not at the front. His art business collapsed during the war but he re-opened in Düsseldorf in 1919. In 1921 he founded "Der Querschnitt" the Cross Section a cultural magazine. Legendary glamorous parties in Flechtheim's gallery overflowed with the glitterati of the new Berlin: movie stars titans of finance prizefighters and artists of every stripe. As Hitler rose to power in the late 1920s and early 1930s Flechtheim became a bête noire because of the art he espoused and championed. In 1933 Sturmabteilung men broke up an auction of Flechtheim's paintings. The Nazis aryanized Flechtheim's gallery as they would many other Jewish businesses and turned it over to Flechtheim's business manager Alex Vömel. After the war former party member Vömel said he didn't even remember who Flechtheim was. The Nazis seized and sold off Flechtheim's private collection as well as the contents of his gallery. Emigration and Death Six months after the Nazis came to power in 1933 Flechtheim penniless fled to Paris and tried to find work with his former business partner Daniel-Henry Kahnweiler. Flechtheim subsequently organized exhibits in London of the paintings of exiled German artists. In London Flechtheim slipped on a patch of ice was taken to a hospital punctured his leg on a rusty nail in his hospital bed developed septicemia leading to amputation of his leg and died.

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."
