Very good. <p>1 First Edition in Journal Form Revised of Einstein's doctoral thesis ranked by his biographer as being on the same level as his 1905 papers on relativity the light quanta and Brownian motion. In his thesis Einstein presented a new theoretical method for determining molecular radii and Avogadro's number the number of atoms or molecules needed to make up a mass equal to a substance's atomic or molecular weight in grams. The thesis appeared in print in the spring of 1905; in the journal version published at the beginning of 1906 Einstein added a brief appendix containing an improved value of Avogadro's number.</p> <p>Einstein's biographer Abraham Pais wrote of Einstein's thesis as follows: </p> <p>"It is not sufficiently realized that Einstein's thesis is one of his most fundamental papers. Histories and biographies invariably refer to 1905 as the miraculous year because of his article on relativity the light-quantum and Brownian motion. In my opinion the thesis is on a par with the Brownian motion article. In fact in some-not all-respects his results on Brownian motion are by-products of his thesis work emphasis ours. This goes a long way toward explaining why the paper on Brownian motion was received by the Annalen der Physik on May 11 1905 only eleven days after the thesis had been completed.</p> <p>"Three weeks after the thesis was accepted this same journal received a copy of the thesis for publication. It was published only after Einstein supplied a brief addendum in January 1906. . . . As a result of these various delays the thesis appeared as a paper in the Annalen der Physik only after the Brownian motion article had come out in the same journal. This may have helped create the impression in some quarters that the relation between diffusion and viscosity-a very important equation due to Einstein and Sutherland-was first obtained in Einstein's paper on Brownian motion. Actually it first appeared in his thesis . . . ." </p> <p>"Quite apart from the fundamental nature of some results obtained in the thesis there is another reason why this paper is of uncommon interest: it has had more widespread practical applications than any other paper Einstein ever wrote . . . . The thesis dealing with bulk rheological properties of particle suspensions contains results which have an extraordinarily wide range of applications. They are relevant to the construction industry the motion of sand particles in cement mixes to the dairy industry the motion of casein micelles in cow's milk and to ecology the motion of aerosol particles in clouds to mention but a few scattered examples. Einstein might have enjoyed hearing this since he was quite fond of applying physics to practical situations" Pais Subtle is the Lord pp. 89-90. </p> <p>Pais notes that during the period 1970-1974 the 1906 journal version of Einstein's thesis was cited four times more often than his 1916 paper on general relativity and eight times more often than his 1905 paper on light quanta.</p> <p>2 First Edition of Einstein's second paper on Brownian motion containing two further methods for finding Avogadro's number.

"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.

In 1916 after publishing his great work on general relativity Einstein returned to the question of blackbody radiation. In November 1916 he wrote to his friend Besso that "a splendid light has dawned on me about the absorption and emission of radiation" quoted in Pais p. 405 one that led him to a new derivation of Planck's radiation law and convinced him of the reality of light-quanta photons. After publishing these results in three papers culminating with the famous "Zur Quantentheorie der Strahlung" 1917 Einstein kept looking for "new ways in which the existence of photons might lead to observable derivations from the classical picture" Pais p. 413. He found none until 1923 when Arthur Compton and Peter Debye independently derived the relativistic kinematics for the scattering of a photon off an electron at rest. The work of Compton and Debye led Wolfgang Pauli to extend Einstein's work of 1917 to the case of radiation in equilibrium with free electrons see Pais p. 414n. "Pauli examined the requirements of detailed balance under Lorentz transformations and found that scattering of light by free electrons must include a term of a form which we would now call stimulated emission . . . Einstein and Ehrenfest then showed that Pauli's results could be obtained by an extension of Einstein's 1917 paper with the unnecessary specialization to discrete energy levels removed . . . The core of Einstein's argument is that the scattering process should be broken into two parts: the absorption of energy from radiation of frequency 1 and the emission of energy as radiation of frequency 2" Lewis p. 42.

19191857Berlin: Königlich Akademie der Wissenschaften 1919. First Edition. Fine. FIRST EDITION IN ORIGINAL WRAPPERS of one of Einstein's major papers on the modification of general relativity and the beginning of his unified field theory. "As so often the case in relativity the story of quantum gravity begins with Einstein himself. Soon after the final formulation of general relativity he pointed out the need for a quantum modification of the theory. In "Do Gravitational Fields Play an Essential Role in the Structure of the Elementary Particles of Matter" he began to speculate whether gravitation plays a role in the atomistic structure of matter: There are reasons for thinking that the elementary formations which go to make up the atom are held together by gravitational forces. The above reflections show the possibility of a theoretical construction of matter out of the gravitational field and the electromagnetic field alone. "In order to construct such a model of an 'elementary particle' Einstein shows that it is necessary to modify the original gravitational field equations. The major interest of this paper is that his attention now shifted from possible quantum modifications of general relativity to the search for a unified theory of the electromagnetic and gravitational fields on the basis of which he hoped to explain the structure of matter. Quantum effects are to be derived from such a theory rather than postulated ad hoc. Einstein remained committed to this approach for the rest of his life: the search for a 'natural' mathematical extension of the general theory in the hope that such a theory would somehow explain the quantization of matter and energy" Iyer and Bhawal Black Holes Gravitational Radiation and the Universe.

Einstein's correction to his formula for the viscosity coefficient = 1 a key equation in his 1905 doctoral thesis in which he had presented a new theoretical method for determining molecular radii and Avogadro's number. In 1910 Jacques Bacelin a pupil of French physicist Jean-Baptiste Perrin obtained experimental results indicating a possible error in Einstein's formula. "That prompted Einstein after an unsuccessful attempt to find an error to ask his student and collaborator Ludwig Hopf to check his calculations and arguments . . . Hopf did find an error in the dissertation namely in the derivatives of some velocity components and obtained for a corrected coefficient 2.5 . . .In early 1911 Einstein submitted his correction for publication and recalculated Avogadro's number.

1922432871922. <p>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. </p> <p>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. </p> <p>Einstein and Ehrenfest addressed one of these difficulties—connected with space quantization—in their joint paper in which </p> <p>"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. </p> <p>Pais Subtle is the Lord p. 328.

In 1915 Einstein and Dutch physicist Wander Johannes de Haas conducted gyromagnetic experiments leading to the discovery of the Einstein-de Haas effect which corresponds to the mechanical rotation induced in a ferromagnetic cylinder suspended inside a coil when an impulse of electric current is sent through the coil. Einstein was very enthusiastic about the experimental results stating that he and de Haas had "given firm proof of the existence of Ampère's molecular currents" quoted in Pais Subtle is the Lord pp. 245-246. Einstein and de Haas published their results in a paper published earlier in 1915 see Weil 73; the present "Notiz" is a response to a communication from American physicist Samuel Jackson Barnett who had begun performing similar experiments in 1909 and obtained results complementing those of Einstein and de Haas.

EXTREMELY RARE AUTHOR'S OFFPRINT "Überreicht von den Verfassern" IN ORIGINAL WRAPPERS OF THE FIRST PRINTING OF EINSTEIN AND GROSSMANN'S FURTHER DEVELOPMENT OF THE CRITICAL "ENTWURF" THEORY OF 1913. "Einstein returned from Prague to Zurich in the summer of 1912. He had by then already formulated the fundamental physical principles of the general relativity theory of gravitation and was now searching for their mathematical structure. At the E.T.H. the Swiss Federal Institute of Technology in Zurich where he now returned as professor of theoretical physics Einstein met again his old fiend and former fellow student Marcel Grossmann who was now a professor of mathematics and his colleague. With Grossmann and under his guidance Einstein studied the mathematical literature especially the theory of invariants and the absolute differential calculus of Chirstoffel Ricci Levi-Civita and others. Einstein developed the mathematical structure of his theory jointly with Grossmann and in his celebrated paper on the general theory of relativity in 1916 he acknowledged the help which his friend had given him. It was Grossmann's help which had Einstein said 'spared me not only the study of the relevant mathematical literature but who Grossmann also assisted me in searching for the field equations of gravitation.' This study of mathematical literature and the search for the proper mathematical tools led to several joint papers with Grossmann during Einstein's all too brief stay in Zurich. These papers contained the first attempts toward a generalized theory of relativity using new mathematical tools and gave full expression to Einstein's earlier physical insights" Jagdish The Golden Age of Theoretical Physics. The first of Einstein's papers to present his collaborative work with Grossmann the famous "Entwurf" paper appeared in the summer of 1913; the present paper based on a lecture given on September 9 1913 to the 96th annual meeting of the Swiss Society for Natural Sciences in Frauenfeld provides further details on the new generalized theory of relativity.

FIRST EDITION COMMERCIAL OFFPRINT ISSUE of Einstein's breakthrough work on general relativity: the famous "Entwurf" paper. "In this book Einstein and Grossman investigated curved space and curved time as they relate to a theory of gravity. They presented virtually all the elements of the general theory of relativity with the exception of one striking omission: gravitational field equations that were not generally covariant. Einstein soon reconciled himself to this lack of general covariance through the 'hole argument' which sought to establish that generally covariant gravitational field equations would be physically uninteresting. Einstein did not adopt the gravitational field equations until late in 1915 in his final formulations of the general theory.

19312331Lancaster: Physical Review 1931. First Edition. Original wrappers. Fine. FIRST EDITION FIRST PRINTING IN ORIGINAL WRAPPERS of Einstein's paper outlining a thought experiment to suggest that the uncertainty principle requires the acknowledgement of an indeterminate past. "To Heisenberg at the 1920's only the prediction of the future was important and the mathematical theory assisted him to calculate the probability of the end-state given the initial state: the description of the intermediate development of the system between two objectively recorded or recordable states did not seem to correspond to physical reality. <br /> <br /> "On the other hand Einstein as a critic of quantum physics did not admit Heisenberg's standpoint especially that the indeterminacy principle does not refer to the past. In the paper 'Knowledge of Past and Future in Quantum Mechanics' 1931 Einstein proposed an imaginary experiment in which 'the possibility of describing the past path of one particle would lead to predictions as to the future behavior of a second particle of a kind not allowed in the quantum mechanics.' So Einstein concluded that 'the principle of the quantum mechanics must involve an indeterminacy in the description of past events which is analogous to the indeterminacy in the prediction of future events.'<br /> <br /> "This should be understood in the context of Einstein's argument against the 'completeness' of quantum physics just in the same way that the purpose of the EPR argument 1935 was to show that the 'completeness' of quantum physics would lead to absurdity. In other words Einstein did not positively assert the existence of indeterminate past events but only intended to deduce it as the necessary conclusion of the 'completeness' of quantum physics.<br /> <br /> "The problem of the 'indeterminate' past re-appeared about fifty years later in J. A. Wheeler's discussion of the 'delayed-choice' experiment. This experiment is not an imaginary but an actual one which uses one particle say photon instead of two particles in Einstein's case.<br /> <br /> "After confirming the fact that what we can say of past events is decided by delayed choices made in the near past and now Wheeler discusses the possibility that the phenomena called into being by the present decision can reach backward in time even to the earliest days of the universe. He says:<br /> <br /> 'To use other language we are dealing with an elementary act of creation. It reaches into the present from billions of years in the past. It is wrong to think of the past as "already existing" in all detail. The "past" is theory. The past has no existence except as it is recorded in the present. By deciding what questions our quantum registering equipment shall put in the present we have an undeniable choice in what we have the right to say about the past.'<br /> <br /> "The interpretation of the indeterminacy principle will be altered if we accept the concept of the past indeterminacy. Heisenberg originally considered this principle as the limit of the exactitude of two incommensurable quantities at the simultaneous measurement. But the indeterminacy of past events which have not been recorded have a connection not with their simultaneous measurability but rather with the definability of their historic routes. That the definition of the past route or history of a particle depends on the present choice of an experimenter is the meaning of the 'indeterminate past'" Yutaka Tanaka "The 'Individuality of a Quantum Event".

FIRST PRINTING IN ORIGINAL WRAPPERS IN FINE CONDITION of Einstein's famous November 4 1915 paper introducing his new version of general relativity. By autumn 1915 Einstein experienced a "crisis" in his work on his gravitational equations and the general theory of relativity forcing him to abandon several key elements of his earlier work. In October 1915 "Einstein shifted his focus from the physical strategy which emphasized his feel for the basic principles of physics and returned to a greater reliance on a mathematical strategy which made use of the Riemann and Ricci tensors. 'Einstein's reversal' writes John Norton 'parted the waters and led him from bondage into the promised land of general relativity'. "The result was an exhausting four-week frenzy during which Einstein wrestled with a succession of tensors equations corrections and updates that he rushed to the Prussian Academy in a flurry of four Thursday lectures. It climaxed with the triumphant revision of Newton's universe at the end of November 1915" Isaacson. In this November 4th paper and lecture On the General Theory of Relativity Einstein presented "to the plenary session of the Prussian Academy a new version of general relativity" explaining "that he had 'completely lost confidence' in the equations he proposed in October 1914. His answers were still not entirely right. There was still one flaw a much smaller one which he eliminated three weeks later. But the road lay open. He was lyrical. 'No one who has really grasped it can escape the magic of this new theory'" Pais. Three weeks later - on November 25 1915 - Einstein did indeed eliminate the flaw and "presented to the physics-mathematics section of the Prussian Academy of Sciences a paper in which 'finally the general theory of relativity is closed as a logical structure'. The work is done" Pais. See: Isaacson Einstein pp. 211-221 and Pais Subtle is the Lord pp.250-261. Note: Einstein's November 11 paper was titled "Zur allgemeinen Relativitatstheorie II" but rather than a continuation or advancement of the November 4 paper it was a step backwards introducing a serious mistake that he would correct by November 25.
