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.

Signed Typescript Statement Later Published as the Foreword to G. H. Shikmoni's Humanistisches Judentum Humanistic Judaism

1943réf. 3079Princeton NJ: np 1943. first. Very Good. AN EXTRAORDINARY SIGNED 1943 STATEMENT DEFINING EINSTEIN'S CONCEPTION OF JUDAISM THROUGH REASON AND SPINOZA WHILE WARNING AGAINST "CLERICAL DOMINATION" IN A FUTURE JEWISH HOMELAND. Of course we all know Einstein as the great scientist. From the theoretical physicists among us to those of use who barely survived high school physics we are all captivated by the man and accept his place at the outer limits of human intellectual capacity. Yet it's when Einstein leaves the world of relativity and theoretical physics that we are often most drawn to his never-ending charisma. Especially exciting to so many of us are his deep convictions about human affairs especially politics and religion. Einstein famously was irreligiously religious. Born to a secular Jewish family his upbringing lacked the complex ritual we associate with Orthodox Judaism. He briefly became curious about religiosity as a child but his attempts at following religious ritual and doctrine ended a few years later as he confronted the conflict between scientific ideas and Biblical stories. Yet one still sees a deep spirituality in Einstein who saw a special camaraderie in the 17th-century Dutch Jewish philosopher Baruch Spinoza. Spinoza was a Jewish radical who had little patience for endless ritual. He did not see God as a being intervening in human affairs but as a great rational force who formed the universe using rational methods. We become close to God therefore by trying to understand the natural world not obeying endless rituals. One can easily see Spinoza's approach as appealing to Einstein. In Spinoza's view the scientist is the holyman his work bringing him closer to God's creations. While in 1943 many of Einstein's contemporaries could accept such a view in seventeenth-century Amsterdam it was another matter: Spinoza was formally expelled from his Jewish community. Shikmoni's Pamphlet & Einstein's Views Humanistisches Judentum Humanistic Judaism was not a conventional commercial publication. It was issued privately in Haifa in 1948 "on behalf of a Circle of Friends" with Einstein's contribution prominently advertised on the title page as a "Geleitwort von Prof. Albert Einstein." Shikmoni's short pamphlet aligns closely with Einstein's view of religion. Its central proposition is quite radical: a genuinely renewed Jewish culture must recover what Shikmoni regards as Judaism's original combination of humanism and a rational worldview. He traces that tradition through Moses and the Prophets incorporates Jesus "the Nazarene" and sees it culminating in Spinoza. For Shikmoni as for Einstein Spinoza offered a way of reconciling Jewish intellectual identity with reason and freedom from religious orthodoxy. Shikmoni's devotion to Spinoza extended beyond this pamphlet. In 1950 he founded the Spinoza House Bet Shpinozah or Spinozaeum in Haifa a center devoted to promoting Spinoza's philosophy in the newly established State of Israel. The organization attracted prominent supporters including David Ben-Gurion and Albert Einstein. The Document The typescript we have here was written by Einstein on his Princeton letterhead in November 1943 in response to Shikmoni's pamphet and would eventually be published as Einstein's foreword to the pamphlet. The pamphlet would not appear until 1948 five years after Einstein wrote these words. It is not difficult to understand why Shikmoni's manuscript made such an impression on Einstein. He recognized in it many of his own ideas about Judaism religion and Spinoza. Indeed in the typescript Einstein begins by admitting that Shikmoni had articulated something that he himself had long felt but had struggled to define: "This little work has made a deep impression on me. It expresses in a clear manner the meaning of Judaism as it had always hovered indistinctly before me." What follows is almost a miniature statement of Einstein's own religious philosophy: "liberation from petrified ritual; adherence to the social ideal formulated so early; struggle against the spirit of unreason in every form; striving toward Spinoza's amor dei intellectualis." Like Spinoza Einstein's Judaism is not defined principally by ritual observance but by ethics reason intellectual freedom and the pursuit of understanding. But Einstein then moves from religion to politics. The typescript is dated November 1943 five years before the establishment of Israel. We see Einstein already contemplating the character of a future Jewish homeland and warning against allowing religious authority to dominate it: "May a favorable fate preserve us from failing to recognize the danger and for a second time in our history falling in our own homeland under clerical domination which over the course of history has alienated several of our finest people from the community." The warning brings us directly back to Spinoza. Einstein had just invoked a Jewish thinker who had himself been expelled from his religious community for his unorthodox ideas; in the very next paragraph he warns of religious authority once again alienating "several of our finest people" from the Jewish community. There is another important feature of the present typescript. When Einstein's statement was finally published as the foreword to Shikmoni's pamphlet in 1948 one of its most forceful phrases had disappeared. Einstein's original reads: "Kampf gegen den Ungeist in jeder Form" "struggle against the spirit of unreason in every form". The entire phrase is omitted from the published version. The present signed typescript therefore preserves a substantive passage from Einstein's original statement that did not survive into its eventual publication. Full German Transcription Diese kleine Schrift hat tiefen Eindruck auf mich gemacht. Sie spricht den Sinn des Judentums wie er mir immer dunkel undeutlich vorschwebte in einer klaren Weise aus. Loslösung vom versteinerten Ritual Festhalten an dem so früh formulierten sozialen Ideal Kampf gegen den Ungeist in jeder Form Streben nach Spinoza's amor dei intellectualis in welchem das soziale und weltanschauliche Ideal des Judentums vereinigt sind. Möge uns ein gutes Schicksal davor bewahren dass wir durch Verkennung der Gefahr zum zweiten Male in unserer Geschichte in unserem eigenen Heim priesterlicher Bevormundung anheimfallen die im Laufe der Geschichte mehrere unserer Besten der Gemeinschaft entfremdet hat. Möge wer anders denkt und fühlt die Kraft aufbringen die hier berührten Fragen vorurteilslos zu erwägen bevor er urteilt. Princeton N.J. November 1943 A. Einstein English Translation This little work has made a deep impression on me. It expresses in a clear manner the meaning of Judaism as it had always hovered indistinctly before me: liberation from petrified ritual; adherence to the social ideal formulated so early; struggle against the spirit of unreason in every form; striving toward Spinoza's amor dei intellectualis in which the social and philosophical ideals of Judaism are united. May a favorable fate preserve us from failing to recognize the danger and for a second time in our history falling in our own homeland under clerical domination which over the course of history has alienated several of our finest people from the community. May those who think and feel differently summon the strength to consider without prejudice the questions touched upon here before passing judgment. Princeton N.J. November 1943 A.

Second edition first printing. 1945 LANDMARK SUMMARY OF NOBELIST ALBERT EINSTEIN'S THEORIES THAT ESTABLISHED MODERN PHYSICS--COPY OF NOBELIST CARLETON GAJDUSEK WHO DISCOVERED KURU THE FIRST PRION DISEASE. 8 inches tall hardcover gray cloth binding gilt title to spine decorative bookplate of D. Carleton Gajdusek to front paste-down signature of D. Carleton Gajdusek to front free endpaper vi 135 pp near fine in very good unclipped jacket with faint splash mark to cover light wear to spine ends and corners in protective mylar sleeve. This first printing of the second edition contains an appendix added by the author discussing advances in the theory of relativity since the first edition in 1921. ALBERT EINSTEIN 1879 – 1955 was a German-born theoretical physicist widely acknowledged to be one of the greatest and most influential physicists of all time. Einstein is best known for developing the theory of relativity but he also made important contributions to the development of the theory of quantum mechanics. Relativity and quantum mechanics are together the two pillars of modern physics. In 1922 he was awarded the 1921 Nobel Prize in Physics "for his services to Theoretical Physics and especially for his discovery of the law of the photoelectric effect". The Meaning of Relativity: Four Lectures Delivered at Princeton University May 1921 is a book published by Princeton University Press in 1922 that compiled the 1921 Stafford Little Lectures at Princeton University given by Albert Einstein. The lectures were translated into English by Edwin Plimpton Adams. The lectures and the subsequent book were Einstein's last attempt to provide a comprehensive overview of his theory of relativity and is his only book that provides an accessible overview of the physics and mathematics of general relativity. The book is made of four lectures. The first is titled "Space and Time in Pre-Relativity Physics". The second lecture is titled The Theory of Special Relativity and discusses the special theory of relativity. The third and fourth lectures cover the general theory of relativity in two parts. Einstein added an appendix to update the book for its second edition published in 1945 offered here. PROVENANCE: DANIEL CARLTON GAJDUSEK 1923-2008 was an American medical doctor and researcher who was co-recipient of the Nobel Prize in Physiology or Medicine in 1976 for his work in Kuru the first prion disease. Gajdusek graduated from Harvard Medical school at age 23 served as head of virological and neurological research at the National Institute for Health in 1958; and inducted into the National Academy of sciences in 1974. Gajdusek's best-known work focused on kuru. This disease was rampant among the South Fore people of New Guinea in the 1950s and 1960s. Gajdusek connected the spread of the disease to the practice of funerary cannibalism by the South Fore. With elimination of cannibalism kuru disappeared among the South Fore within a generation. He proved his hypothesis by successfully transmitting the disease to primates and demonstrating that it had an unusually long incubation period of several years. This was the first demonstration of the infectious spread of a noninflammatory degenerative disease in humans. Subsequently additional human agents belonging to the same group were discovered. They include sporadic familial and variant Creutzfeldt–Jakob disease. Gajdusek recognized that diseases like Kuru and Creutzfeldt–Jakob disease were caused by a new infectious agent that had not yet been identified. Princeton University Press hardcover books

Report on the Relativity Theory of Gravitation

1918réf. 2839London: Fleetway Press 1918. FIRST EDITION. Original wrappers. Fine. THE FIRST INTRODUCTION OF EINSTEIN'S GENERAL RELATIVITY TO THE ENGLISH-SPEAKING WORLD. The groundbreaking first edition 1918 with the second edition 1920 containing the account of Eddington's 1919 expedition proving Einstein's theory both in original wrappers. "Einstein's discovery of the General Theory of Relativity was communicated to the Berlin Academy of Sciences in 1915. Because of the First World War direct communication with physicists in Germany was not possible but the papers were forwarded to Eddington who was then Secretary of the Royal Astronomical Society by Willem de Sitter a personal friend of Eddington's in neutral Holland. The theory is of considerable mathematical complexity but as Einstein stated in the last paragraph of his paper 'scarcely anyone who has fully understood this theory can escape from its magic'. Eddington was the ideal expositor of these ideas in English and within 2 years had written his Report on the Relativity Theory of Gravitation for the Physical Society of London" Malcolm Longair "Bending Space-time". The second edition is notable for containing a new preface that discusses the results of the "eclipse expedition" led by Eddington that verified General Relativity and catapulted Einstein into world-wide fame. This preface precedes Eddington's full report in the Philosophical Transactions. Provenance: Almost certainly Nobel Prize winning physicist's Charles Glover Barkla's copy of the 1918 report with an original 1918 receipt in Barkla's name laid in. Barkla won the 1917 Nobel Prize in Physics "for his discovery of the characteristic Röntgen radiation of the elements". London: Fleetway Press for The Physical Society of London 1918 and 1920.

Quantentheoretische Bemerkungen zum Experiment von Stern und Gerlach

1922réf. 432871922. Einstein Albert 1879-1955 and Paul Ehrenfest 1880-1933. Quantentheoretische Bemerkungen zum Experiment von Stern und Gerlach. Offprint from Zeitschrift für Physik 11 1922. 31-34pp. 229 x 155 mm. Original printed self-wrappers. Light toning but fine otherwise. First Edition Offprint Issue. In 1922 the physicists Otto Stern and Walther Gerlach conducted a now-classic experiment in which a beam of silver atoms was streamed through an inharmonious magnetic field in order to observe the atoms' deflection patterns. Rather than a random and continuous distribution as predicted by classical theory the atoms passing through the field were deflected up or down by a specific amount demonstrating that they had intrinsically quantum properties. The Stern-Gerlach experiment corroborated the Bohr-Sommerfeld model of the atom and strongly influenced later developments in 20th century physics. However the experiment also created some serious difficulties for quantum physicists in the period before the rise of the "new" quantum mechanics. Einstein and Ehrenfest addressed one of these difficulties-connected with space quantization-in their joint paper in which "they dealt in particular with the problem of how the orbits of the atom would obtain their discrete directions which they exhibit while passing through the inhomogeneous magnetic field. Under the assumption that the mechanism causing the orientation was provided by the interaction with the radiation field Einstein and Ehrenfest estimated that for a field strength of 10000 G a change in the direction of the orbit would take place in roughly 1011 s; this long time interval would be reduced in the presence of heat radiation at room temperature . . . to about 109 s. How could they asked the experimental situation be explained which implied that the discrete orientations of the orbits in silver atoms were obtained in less than 10-4 s. In order to deal with this evident puzzle Einstein and Ehrenfest proposed two alternatives: first that the silver atoms were always in the states of spatial quantization; second the orientations of the electron orbits arose from an interaction of the atoms with the radiation field which involved much smaller reaction times . . . However they found that both alternatives created considerable difficulties in the understanding of the atomic processes . . . Thus Einstein and Ehrenfest concluded: 'The difficulties mentioned above show how unsatisfactory are both interpretations of the results found by Stern and Gerlach'" Mehra & Rechenberg The Historical Development of Quantum Theory 1 pp. 443-444.
