1949réf. 133215Munchen: Paul List Verlag 1949. First German edition of this classic work by Frank a famed contemporary of Einstein. Octavo original cloth. Signed by Albert Einstein on the slip to the title page and inscribed by the author on the front free endpaper "To Karl W. Deutsch with the author's compliments Philipp Frank August 10 1950." Philipp Frank was a physicist mathematician and also a philosopher during the first half of the 20th century. He was a logical-positivist and a member of the Vienna Circle. He was influenced by Mach and was one of the Machists criticised by Lenin in Materialism and Empirio-criticism. He studied physics at the University of Vienna and graduated in 1907 with a thesis in theoretical physics under the supervision of Ludwig Boltzmann. Albert Einstein recommended him as his successor for a professorship at the German Charles-Ferdinand University of Prague a position which he held from 1912 until 1938. Very good in a good dust jacket. Much has been written about Albert Einstein technical and biographical but very little remains as valuable as this unique hybrid of a book written by Einstein's colleague and contemporary. Both rich in personal insights and grounded in a deep knowledge of twentieth-century science Phillip Frank's biography anchors the reader with a lucid overview of physics and draws an intimate portrait of the Nobel Prize–winner.

1914réf. 1199Braunschweig: Friedr. Vieweg & Sohn 1914. 1st Edition. FIRST EDITION FULL VOLUME OF THE FRANCK-HERTZ EXPERIMENT: THE FIRST ELECTRICAL MEASUREMENT TO CLEARLY SHOW THE QUANTUM NATURE OF ATOMS - PROOF OF THE QUANTIZED MODEL OF THE BOHR ATOM & OF PLANCK'S QUANTUM THEORY. Note that this volume includes both the first and second Franck-Hertz experiment. In the first they demonstrate that atoms can only absorb and be excited by specific amounts of energy; in the second experiment performed the same year they demonstrate that the frequency of the light emitted following the collision of electrons with mercury atoms corresponds precisely with the energy lost by the electrons in the collision. Franck and Hertz received the Nobel Prize for this work specifically "for their discovery of the laws governing the impact of an electron upon an atom" Nobel Prize Committee. Of equal import this volume also contains a paper by Einstein in which he uses the light quantum hypothesis to give new derivations of Planck's radiation law and Nernst's third law of thermodynamics. His "proofs introduced the quantum hypothesis" Calaprice The Einstein Almanac 40. In 1914 James Franck and Gustav Hertz were working together in the Physics Institute of Berlin and were "particularly interested in ionization i.e. in the process in which an electron is removed from an atom" The Harvest of a Century" p. 102-103. The experiment they devised now known commonly as the Franck-Hertz experiment is "a vivid illustration of the quantization of energy" that relied on methodology so simple "that it is now carried out regularly by undergraduates. They accelerated electrons through a low-pressure gas of mercury. When the electrons' energy reach the energy of a stationary state of mercury they gave up a quantum of energy to the mercury resulting in a stepwise shape to the curve of current through the apparatus. This demonstrated that atoms could absorb energy only in discrete amounts" Peacock The Quantum Revolution 40. "Franck and Hertz had not only shown for the first time that electrons lose their kinetic energy to mercury atoms in energy quanta but also that these energy quanta are equal to the energy of the light emitted by the same atoms if interpreted with Einstein's light-quantum hypothesis.This was the first experimental determination of Planck's constant not using blackbody radiation" Brandt 103.

Catalog published on the occasion of an exhibition of paintings and drawings by George Grosz held during the Spring of 1926 in Berlin at the Galerie Alfred Flechtheim. This catalog features 24 duo-tone and b/w photographic reproductions. Includes a poem by Gottfried Benn and four essay on the artist and his work by Carl Einstein Marc Neven Max Herrmann and Florent Fels. Some age-wear and moderate soiling on wrappers. Upper corners bumped thus slightly affecting pages throughout. Text in German gothic script with one of the four essays in French. Wrappers in overall good- to good interior in good to very good condition. Alfred Flechtheim 1878-1937 was a German art dealer art collector journalist and publisher. 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.

1918réf. 135751918. Mathematics Klein Felix. Autograph Letter Signed 10 November 1918 written in German to a former student and colleague directly references Einstein's recently published General Theory of Relativity and comments on the work of the International Mathematical Education Commission. Composed in the closing days of the First World War the letter places Klein within active scholarly exchange concerning the mathematical implications of relativity which had been formally presented in 1915 and widely disseminated by 1918. Klein long established for his foundational contributions to group theory non-Euclidean geometry and mathematical physics addresses questions raised by "Einstein's theory" noting that he required further reflection to clarify its implications for his own work. The document supports research in the history of relativity German mathematical networks scientific communication during wartime and the institutional organization of mathematics in the early twentieth century. Klein Felix. Autograph Letter Signed 10 November 1918. Two pages written on both sides of a single leaf. In German with accompanying English translation. Addressed to a former student the letter discusses the circulation of lecture manuscripts difficulties in securing copyists during wartime conditions and the intellectual demands posed by Einstein's theory: "A further exploration of my work does not exist yet as I had and still have more thinking to do about questions raised by Einstein's theory to clarify it for myself." Klein also comments critically on the IMUK observing that its published statements are "a display of wasted paper" while acknowledging the commission's broader social significance. He singles out contemporary educational treatises including studies by W. Trost Heinrich Emil Timerding and M. Girndt indicating his sustained engagement with mathematical pedagogy alongside theoretical research. The letter was written days before the November Revolution in Germany and at a moment when academic institutions faced political upheaval and material shortages. Klein's remarks regarding limited copyists and uncertainty about the coming months provide contemporaneous evidence of scholarly life under strained postwar conditions. His reference to Einstein situates the correspondence within the earliest phase of professional reception of general relativity among leading mathematicians while his comments on the International Mathematical Education Commission underscore his longstanding commitment to mathematical instruction and institutional reform. Clean and well preserved with strong legibility and a clear signature. Overall near fine condition. A substantive document of early relativity discourse and mathematical research at the end of the First World War. unknown

réf. H1017Leipzig J. A. Barth 1906 S. 371-381. Halbleinenband der Zeit mit goldgeprägtem Rückentitel gr. 8°. Vorderdeckel etwas berieben.2 St. a. Titel. Text sauber und frisch. bedeutender Botaniker und Nachfolger Dryanders als Bibliothekar Joseph Banks' ist noch heute durch seine Entdeckung der sog. Brownschen Bewegung auch Brownschen Molekularbewegung Brownian Movement im Jahr 1827 bekannt. Bei Beobachtungen mit dem Mikroskop fiel ihm die unregelmäßige Zitterbewegung von auf der Wasserfläche dahintreibenden Blütenstaubpartikeln auf. Brown konnte keine Erklärung dafür finden. Es war Albert Einstein der 1905 herausfand dass sie durch Zusammenstöße mit unter dem Mikroskop nicht sichtbaren Atomen und Molekülen herrührt. Einstein veröffentlichte seine Beobachtung in den Abhandlungen "Über die von der molekularkinetischen Theorie der Wärme geforderte Bewegung von in ruhenden Flüssigkeiten suspendierten Teilchen" Annalen der Physik 4. Folge Bd. 17 1905 und – hier vorliegend - "Zur Theorie der Brownschen Bewegung" dass. Bd. 19 1906. Die erfolgreiche Erklärung der brownschen Bewegung gilt als Meilenstein auf dem Weg zum wissenschaftlichen Nachweis der Existenz der Moleküle und damit der Atome. Robert Brown 1773-1858 zählte zu den bedeutendsten Botanikern der ersten Hälfte des 19. Jahrhunderts. Nach dem Studium der Medizin und Botanik in Edinburgh wurde er zunächst als Militärarzt im Norden Irlands tätig. 1798 machte er die Bekanntschaft von Joseph Banks – ein Treffen das entscheidend für sein ganzes weiteres Leben sein sollte. Banks bot ihm eine Stelle als Naturwissenschaftler auf Flinders Expedition zur Erforschung der australischen Küsten an. Brown nahm an und arbeitete in der Folge eng mit dem Pflanzenmaler Ferdinand Bauer zusammen. Als Flinders aufgrund des untragbaren Zustandes des Expeditionsschiffs "Investigator" gezwungen war die Reise vorzeitig abzubrechen blieben Brown und Bauer in Port Jackson zurück um ihre Forschungen bis zur Rückkehr Flinders' fortzuführen. Brown ging in der Folge nach Van Diemens-Land Tasmanien Bauer auf die Norfolk-Insel. 1805 traf man sich in Sydney wieder und trat die Heimreise an. Kurz nach seiner Rückkehr wurde Brown zum Bibliothekar der Linnéan Society. 1810 nach dem Tod Dryanders übernahm er dessen Stelle in der Bibliothek Banks'. Letzterer gab Brown testamentarisch das Recht auf lebenslange Nutzung seiner Sammlungen und seiner Bibliothek. Als man diese 1827 ins British Museum verlegte wurde Brown zum Bibliothekar und Kurator der dortigen botanischen Abteilung. Nach Banks' Tod gab Brown seine Stellung als Bibliothekar der Linnéan Society auf und fungierte von 1849 bis 1853 als deren Präsident. Bereits 1839 hatte man ihm für seine Forschungen über den pflanzlichen Befruchtungsprozess die Copley-Medaille verliehen. unknown

DISCOVERY OF STIMULATED EMISSION OF RADIATION THE PRINCIPLE OF THE LASER INSCRIBED BY EINSTEIN TO A FELLOW NOBEL LAUREATE. First edition complete journal issue in original printed wrappers inscribed by Einstein to fellow Nobel Laureate Walther Bothe. "This work represents a major step forward in quantum theory" Calaprice p. 297. It introduced the concept of stimulated emission of radiation the theoretical basis for the laser; it also contained a new derivation of Planck's radiation law which provided as a by-product a justification of the frequency rule forming the basis of Bohr's theory of atomic spectra. "According to Albert Einstein when more atoms occupy a higher energy state than a lower one under normal temperature equilibrium it is possible to force atoms to return to an unexcited state by stimulating them with the same energy as would be emitted naturally" Britannica. This is 'stimulated emission.' "To claim that Einstein almost invented the laser would be an exaggeration but the laser's underlying mechanism stimulated emission of radiation was a creation of his radiation theory" Kleppner pp. 32-33. "During the summer of 1916 less than a year after he had completed the general theory of relativity Einstein made a new major contribution to the quantum theory. The two papers he wrote then deal with the quantum theory of radiation by arguments that do not depend on the classical electromagnetic theory as had all earlier treatments of Planck's radiation law . When Einstein returned to the radiation problem in 1916 the quantum theory had undergone a major change. Niels Bohr's papers had opened a new and fertile domain for the application of quantum concepts - the explanation of atomic structure and atomic spectra. In addition Bohr's work and its generalizations by Arnold Sommerfeld and others constituted a fresh approach to the foundations of the quantum theory of matter" DSB. In this paper "Einstein considers a system of atoms in equilibrium with an external radiation field. An atom can change its internal energy state by absorbing or emitting radiation. Einstein introduces three basic assumptions about these exchanges of energy between matter and field. First the probability of absorption of radiation is proportional to the radiation density. Second there are two kinds of emission processes: one - spontaneous - following a law like that of radioactive decay; the other - stimulated - induced by the radiation field and with probability proportional to the radiation density. Third at equilibrium the atoms are distributed among their internal states according to the Boltzmann distribution law. From these assumptions Planck's law follows in a simple way. Einstein was very pleased with his derivation which he characterized in a letter to Besso: 'An amazingly simple derivation of Planck's formula I should like to say the derivation.' As a bonus from his derivation Einstein found that the energy difference between two internal energy states of the atom had to be equal to hv with v the frequency of the radiation absorbed or emitted in transitions between these two states thus confirming one of the postulates of Niels Bohr's theory of spectra" Papers 6 xxiii-xxiv. "Einstein meant the second part of this study a proof of the oriented character of the emission process to be his most essential contribution to quantum radiation theory this second paper was published later in 1916 as 'Zür Quantentheorie der Strahlung'. Instead Bohr gave more importance to the new deduction of the blackbody law; for this deduction reinforced the basic assumptions of his atomic theory and completed them with a statistical description of radiation processes" Darrigol p. 120. Provenance: Inscribed by Einstein on front wrapper "für. Dr Bothe" i.e. Walther Bothe 1891-1957. "In 1929 in collaboration with W. Kolhörster Bothe introduced a new method for the study of cosmic and ultraviolet rays by passing them through suitably arranged Geiger counters and by this method demonstrated the presence of penetrating charged particles in the rays and defined the paths of individual rays. For his discovery of the 'method of coincidence' and the discoveries subsequently made by it which laid the foundations of nuclear spectroscopy Bothe was awarded jointly with Max Born the Nobel Prize in Physics 1954" . While Einstein commended Planck's epoch-making derivation of his radiation law in 1900 which ushered in the quantum era he had also noted its limitations. Einstein also saw inconsistencies in Planck's derivation of his law. For Einstein this inconsistency was no reason to reject Planck's quantum theory but it was a reason to study the foundations of traditional radiation theory and if needed revise them. "As Einstein had noted in 1906 Planck's derivation of the Rayleigh-Jeans law uν = 8πν2/c3 kT between average resonator energy uν and radiation spectrum ν only applied to classical resonators T is the temperature k is Boltzmann's constant. A new quantum-theoretical picture of the interaction between matter and radiation was needed. Einstein found it in the summer of 1916 after the completion of his general theory of gravitation left him more time for quantum meditation. "The new picture presumably emerged from a combination of three elements: Einstein's derivation of the law of photochemical equivalence his analogy between quantum states and chemical species and Niels Bohr's theory of atomic spectra. According to Bohr atoms and molecules can only exist in a series of quantum states S0 S1 . . . Sn . . . with well-defined energies E0 E1 . . . En . . . Their interaction with radiation occurs through quantum jumps with characteristic values of the frequency of the emitted or absorbed radiation. Regarding the quantum states as chemical species and remembering his photochemical reasoning Einstein knew that he could derive Wien's law by balancing the absorption process Sn hν → Sn1 with the emission process Sn1 → Sn hν and by making the probability of the first reaction proportional to the density of radiation at frequency ν. Something in this reasoning needed to be altered in order to get Planck's law instead of Wien's. "At this point Einstein appealed to an analogy between classical and quantum theory. According to classical theory an oscillating dipole spontaneously emits radiation whether or not radiation is initially present in its surroundings. When external radiation encounters this dipole it may either be absorbed if the phase of the incoming wave agrees with that of the oscillator or it may be amplified in the contrary case. In the quantum theory of radiation Einstein similarly admitted the existence of three kinds of processes: spontaneous emission Ausstrahlung absorption negative Einstrahlung and stimulated emission positive Einstrahlung. The modern terminology is Bohr's. For the probability per time unit of the respective sorts of quantum jump Einstein assumed the forms Anm ÏνBnm ÏνBmn where n is the upper quantum state m the lower one and Ïν is the density of radiation at the frequency ν. "Einstein did not say much on the nature of the probabilities he thus introduced. He only commented that his theory had the weakness to leave to chance the instant and direction of the spontaneous emission of light. He also noted the similarity between spontaneous emission and radioactive decay. Undoubtedly he would have preferred a theory in which the emission and absorption probabilities were deduced from an underlying deterministic theory. He nonetheless expressed his 'full trust in the present way of reasoning'. The probabilistic description of the interaction was a natural counterpart of the discrete character of quantum states: if a quantum system evolves mostly through quantum jumps then the probability of a quantum jump obviously is the main quantity of physical interest. Instead of speculating on the precise timing and fine structure of the jumps Einstein proceeded to show what could be done by means of the new probability coefficients. "At thermal equilibrium Einstein reasoned statistical mechanics requires the number of atoms in a quantum state n to be proportional to exp−En /kT. The kinetic equilibrium between the atoms and surrounding radiation further requires that the number of quantum jumps from m to n should be equal to the number of reverse jumps: ÏνBnm exp−Em /kT = ÏνBnm Anm exp−En /kT. In the high temperature limit for which Ïν → ∞ this condition gives Bnm = Bmn. Therefore the equilibrium value uν of the density Ïν is given by uνexpEn − Em/kT - 1 = Anm / Bnm. According to a thermodynamic theorem by Wien uν/ν3 must be a function of ν/T only. Hence En − Em must be proportional to ν. Einstein thus derived Bohr's strange frequency rule ΔE = hν with complete generality and without recourse to any of the empirical laws of spectra. He then required the expression of uν to agree with the Rayleigh-Jeans law in the low-frequency limit. The outcome was Planck's law as well as the relation Anm / Bnm = 8πhν3/c3 between Einstein's two probability coefficients . "Einstein's new theory of radiation is now remembered for the introduction of stimulated emission which famously permitted the conception of masers and lasers. For Einstein and for his contemporaries the importance of these memoirs lay elsewhere. First Einstein filled an important gap in the derivation of Planck's law by means of a simple statistical description of radiation processes. Second he corroborated two basic assumptions of Bohr's atomic theory: the existence of stationary states and the frequency rule. In this regard it should be emphasized that before Einstein's and Sommerfeld's contributions of 1916 Bohr believed that his frequency rule only applied to strictly periodic systems. For instance he regarded the Zeeman effect as a violation of this rule. Einstein's new considerations established its complete generality" Darrigol in Cambridge Companion to Einstein pp. 134-136. "The implication of Einstein's theory of stimulated emission was that if one arranges for a large number of atoms to be in identical excited states a stray photon of the right energy can stimulate one atom to emit another photon which stimulates another. and all the atoms release their excess energy in a sudden cascade. What's more the photon released by stimulated emission will be in phase - coherent - with the one that stimulated it and so all the light produced in the cascade will be coherent. "In 1955 American physicist Charles Townes of Columbia University in New York an expert in molecular spectroscopy and his co-workers showed how stimulated emission could be used to make a device for generating or amplifying microwaves which they called a maser microwave amplified stimulated emission of radiation. Three years later Townes and Arthur Schawlow explained how to extend the idea to visible and infrared frequencies to make an 'optical maser' - in effect the laser. "They proposed using ordinary incoherent light to pump atoms into an excited state setting up the 'population inversion' in which the atoms are primed to return to their ground state by emitting photons. And their design used an optical cavity - basically two mirrors between which photons would bounce - to trap the emitted photons while they stimulated more emission. The device they explained would generate 'extremely monochromatic single-wavelength and coherent light'. Theodore Maiman of the Hughes Research Laboratories in Malibu California described such a device using a ruby crystal already used for masers as the lasing medium in 1960" 'A century ago Einstein sparked the notion of the laser' Physics World History Blog 31 August 2017.
