192188645Berlin, Julius Springer, 1921, in-8, 20 pp, Broché, couverture crème imprimée de l'éditeur, Première édition de cette conférence prononcée par Einstein (1879-1955) à l'occasion de la séance commémorative de l'Académie prussienne en l'honneur de Frédéric le Grand. Le physicien y résume ses théories sur la géométrisation de la physique et de la relativité, ainsi que sur la relation des mathématiques au monde : "Comment est-il possible que la mathématique, qui est un produit de la pensée humaine et indépendante de toute expérience, puisse s'adapter d'une si admirable manière aux objets de la réalité ? La raison humaine serait-elle donc capable, sans avoir recours à l'expérience, de découvrir par la pensée seule les propriétés des objets réels ?" L'opuscule a été publié l'année où il reçut le prix Nobel. Cachet ex-libris du révolutionnaire Russe et bibliophile Marcel Bekus (1888-1939). Bon exemplaire. Rares rousseurs marginales, agrafes oxydées. Couverture rigide

DISCOVERY OF STIMULATED EMISSION OF RADIATION<br /> THE PRINCIPLE OF THE LASER<br /> INSCRIBED BY EINSTEIN TO A FELLOW NOBEL LAUREATE. <p>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. </p> <br /> <p>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" .</p> <br /> <p>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. </p> <br /> <p>"As Einstein had noted in 1906 Planck's derivation of the Rayleigh-Jeans law</p> <br /> <p>uν = 8πν2/c3 kT</p> <br /> <p>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.</p> <br /> <p>"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. </p> <br /> <p>"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</p> <br /> <p>Anm ÏνBnm ÏνBmn</p> <br /> <p>where n is the upper quantum state m the lower one and Ïν is the density of radiation at the frequency ν.</p> <br /> <p>"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.</p> <br /> <p>"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:</p> <br /> <p>ÏνBnm exp−Em /kT = ÏνBnm Anm exp−En /kT.</p> <br /> <p>In the high temperature limit for which Ïν → ∞ this condition gives</p> <br /> <p>Bnm = Bmn.</p> <br /> <p>Therefore the equilibrium value uν of the density Ïν is given by</p> <br /> <p>uνexpEn − Em/kT - 1 = Anm / Bnm.</p> <br /> <p>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</p> <br /> <p>Anm / Bnm = 8Ï€hν3/c3</p> <br /> <p>between Einstein's two probability coefficients .</p> <br /> <p>"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.</p> <br /> <p>"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.</p> <br /> <p>"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.</p> <br /> <p>"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.</p> <br /> <p>Weil 85.

"Professor Einstein is better known as a physicist than as a Zionist. Yet for many years he has given abundant proof both of a keen interest in Zionism and of a penetrating insight into its underlying ideas. He is impelled to Zionism by his acute consciousness of the excessive price at which the blessings of assimilation are bought by the Jewish communities of the Western world which for him are mainly represented by that of Germany. The price is a loss of solidarity of moral independence and self-respect. These in his view can be regained only if assimilated Jews find some common task of absolute human value to which they can bend their corporate energies as Jews. Such a task is to be found in the restoration of Jewish national life in Palestine." - Introduction. Unmarked with average wear. Backstrip lettering faded. Binding tight.

Einstein was invited to give a lecture at the University of Nottingham by a lecturer there Henry Brose who also acted as interpreter. Einstein came with his wife Elsa on 6th June 1930. He was due to start the lecture at 3.45pm but did not arrive until 6.30 as he took a detour to visit the birth place of Isaac Newton. The blackboard on which he wrote was quickly varnished over when the lecture was over and is still preserved in the university.

Einstein discusses the concept of the aether in relation to his theory of relativity. This lecture examines the historical role of the aether in physics and its transformation under relativity. His conclusion is that relativity does not bring back the classical aether but introduces a new understanding of space as an active structured entity. The text of this speech delivered at Leiden University was also translated into French in 1921. The English translation appeared in Einstein's "Sidelights of Relativity" published at London in 1922. Einstein's manuscript is now kept in the Bibliotheca Bodmeriana Geneva. - Weil 111; Boni Russ and Laurence 115; Roller/Goodman I 354; Seelig 131; Schilpp-Shields 131. SCIENCE: PHYSICS ; Berlin, (E.
