First edition journal issues of three important early papers by Einstein. In the first paper “Einstein suggested that light be considered a collection of independent particles of energy which he called ‘light quanta.’ Such a hypothesis he argued would provide an answer to the problem of black-body radiation where classical theories had failed and would also explain several puzzling properties of fluorescence photoionization and the photoelectric effect” Norman. It was for this paper together with one of the photoelectric effect “Zur theorie der Lichterzeugung und Lichtabsorption” published in 1906 that Einstein was awarded the Nobel Prize in Physics in 1921. The second paper proved according to Einstein himself that “according to the molecular theory of heat bodies of dimensions of the order of 1/1000 mm. suspended in liquid experience apparent random movement due to the thermal Brownian molecular movement quoted by R.W. Clark Einstein New York 1984 p. 87. Experimental verification of the predictions made in this paper contributed to proving the physical reality of molecules. The third paper on the electodynamics of moving bodies was Einstein’s first statement of the special theory of relativity. In it he argued that all motion is relative to the inertial system in which it is measured and that matter and energy are equivalent. As he himself remarked “it modifies the theory of space and time.” I: Weil 6; Norman 689; II: Weil 8 Norman 690; III: Weil 9 Dibner Heralds of Science 167; Grolier/Horblit 26b Norman 691A.

“Ueber die von der molekularkinetischen Theorie der Waerme geforderte Bewegung von in ruhenden Fluessigkeiten suspendierten Teilchen” in Annalen der Physik 4. Folge 17 Band No. 8

1905Best.-Nr. 32820546FIRST EDITION. "On the Movement of Small Particles Suspended in a Stationary Liquid Demanded by the Molecular Kinetic Theory of Heat" appears here on pp. 549-560. This landmark paper on Brownian motion is one of the three great papers from 1905 Einstein annus mirabilis. Although most physicists and chemists accepted the idea of atoms as a useful concept in 1905 many still questioned whether they actually existed. Einstein later claimed that "my major aim in this research was to find facts which would guarantee as much as possible the existence of atoms of finite size." In 1827 botanist Robert Brown had used a microscope to look at dust grains floating in water. He found that the floating grains were moving about erratically a phenomenon that became known as "Brownian motion." In this paper Einstein proved the reality of these molecules and their motions by producing the first statistical physics analysis of Brownian motion. French physicist Jean Perrin used Einstein's results to experimentally determine the mass and the dimensions of atoms thereby conclusively verifying Dalton's atomic theory first proposed in 1808. "Eventually the experimental evidence supporting Einstein's theory of Brownian motion became so compelling that the naysayers were forced to accept the existence of material atoms. His fundamental work on applying statistical methods to the random motions of Newtonian atoms also led to his insights into the photo electric effect through the discovery of a critical connection between his statistical theory of heat and the behavior of electromagnetic radiation. This was the first step in his goal to unify the two fields" APS. Complete issue removed from bound volume. Very good.

Zur Theorie der Lichterzeugung und Lichtabsorption. Offprint from Annalen der Physik 4. Folge 20. Bd. 1906

1906Best.-Nr. 6413Leipzig: Johann Ambrosius Barth 1906. First edition. First edition a very rare author's presentation offprint with 'Überreicht vom Verfasser' from the library of the eminent German physicist Arnold Sommerfeld of this important sequel to Einstein's revolutionary 1905 paper introducing the light-quantum hypothesis - the foundation of quantum theory. In this follow- up work Einstein further develops the implications of his light-quantum hypothesis arguing that Max Planck's black-body radiation law implicitly relies on the same assumption: that light itself consists of discrete quanta of energy. . EINSTEIN ON HIS LIGHT-QUANTUM HYPOTHESIS . First edition very rare author's presentation offprint "Überreicht vom Verfasser" from the library of the great German physicist Arnold Sommerfeld of this brilliant follow-up to Einstein's landmark 1905 paper on the photoelectric effect for which he was awarded the 1921 Nobel Prize in physics. "Thomas Kuhn has argued that it is not to Planck in 1900 but to Einstein in 1905 that we owe the origins of quantum theory" Cassidy. In the 1905 paper 'On a heuristic point of view concerning the production and transformation of light' Einstein had explained the photoelectric effect-the emission of electrons from a metal when irradiated by light-by making the revolutionary proposal that light rather than consisting of continuous waves was instead made up of discrete particles of energy "light quanta" which transferred their entire payload of energy to an electron on impact. In the 1905 paper Einstein made use of Planck's formula for blackbody radiation which had introduced the concept of energy quantization. "In a companion paper published in 1906 offered here Einstein exposed appeal to the quantum as fundamentally counter to the ethos of classical physics: 'the theoretical bases on which Planck's radiation theory rests are different from those of Maxwell's theory'. Planck had not initially intended to quantify light-radiation itself but Einstein demonstrated that his own 'light-quantum hypothesis' was implicit in Planck's earlier work" Honner p. 31. "At first Einstein believed that the light-quantum hypothesis was merely 'heuristic': light behaved only as if it consisted of discontinuous quanta . In his 1906 paper Einstein used his statistical mechanics to demonstrate that when light interacts with matter Planck's entire formula can arise only from the existence of light quanta-not from waves" Cassidy. As Einstein stated when he published the 1905 paper "Planck's theory of radiation seemed to me in a certain respect the antithesis of my own. New considerations which are presented in section 1 of this paper demonstrated to me however that the theoretical bases on which Planck's radiation theory rests are different from those of Maxwell's theory and of electron theory. The difference furthermore is precisely that Planck's theory implicitly makes use of the light-quantum hypothesis" p. 199 of the present paper translation from Kuhn p. 182. Later in the paper p. 203 Einstein is forced to make the following assumption: "Although Maxwell's theory is not applicable to elementary resonators the average energy of such a resonator in a radiation field is the same as that which one would compute from Maxwell's theory". "That statement marks the emergence of the basic paradox of the old quantum theory. The theory has recourse to both Maxwell's equations and those of classical mechanics but its further formulation is incompatible with one or both of those classical theories. Other physicists were to exploit the resulting inconsistency as an argument against any form of quantum discontinuity and Einstein himself was deeply disturbed by it . But neither he nor anyone else was successful in finding a classical resolution of the quantum paradox. When two decades later Bohr and others found a way to resolve it Einstein was unable to accept their fundamentally non-classical interpretation" Kuhn pp. 184-185.

Provenance: Arnold Sommerfeld 1868-1951 his signature and characteristic numbering in red pencil '8' on front cover. "The son of a physician Sommerfeld was educated at the University of Königsberg. After teaching briefly at the universities of Göttingen Clausthal and Aachen he was appointed professor of physics at the University of Münich in 1906. Sommerfeld should have retired in 1936 in favour of his pupil Werner Heisenberg. Opposition from the Nazi party to Heisenberg's appointment prolonged Sommerfeld's tenure and it was not in fact until late 1939 that he finally retired to be succeeded not by Heisenberg but by Wilhelm Müller a Nazi aerodynamicist without a single publication in physics to his credit. Although Sommerfeld and Heisenberg were not Jewish they were regarded by the Nazis as Jewish sympathizers. Sommerfeld however survived the war and returned to his Münich chair in 1945 continuing to work at physics until he died in a car accident in 1951" Oxford Reference. "Arnold Sommerfeld was one of the most distinguished representatives of the transition period between classical and modern theoretical physics. The work of his youth was still firmly anchored in the conceptions of the nineteenth century; but when in the first decennium of the century the flood of new discoveries experimental and theoretical broke the dams of tradition he became a leader of the new movement and in combining the two ways of thinking he exerted a powerful influence on the younger generation. This combination of a classical mind to whom clarity of conception and mathematical rigour are essential with the adventurous spirit of a pioneer are the roots of his scientific success while his exceptional gift of communicating his ideas by spoken and written word made him a great teacher" Max Born p. 275. "Einstein started to study black-body radiation well before 1905. Mach's Wärmelehre which Einstein read in 1897 or shortly thereafter contains two chapters on thermal radiation culminating in a discussion of Kirchhoff's work. Kirchhoff showed that the energy emission spectrum of a perfectly black body defined as one absorbing all incident radiation at a given temperature is a universal function of the temperature and wavelength. He inferred that equilibrium thermal radiation in a cavity with walls maintained at a certain temperature behaves like radiation emitted by a black body at the same temperature. "H. F. Weber Einstein's physics professor at the ETH attempted to determine the universal black-body radiation function. He made measurements of the energy spectrum and proposed an empirical formula for the distribution function . anticipating Wien's formulation of the displacement law for black-body radiation. Weber described his work in a course at the ETH given during the winter semester of 1898-1899 for which Einstein registered. "By March 1899 Einstein had started to think seriously about the problem of radiation. In the spring of 1901 he was closely following Planck's work on black-body radiation. Originally Planck had hoped to explain irreversibility by studying electromagnetic radiation but came to recognize that this could not be done without introducing statistical elements into the argument. In a series of papers published between 1897 and 1900 Planck utilized Maxwell's electrodynamics to develop a theory of thermal radiation in interaction with one or more identical charged harmonic oscillators within a cavity. He was only able to account for the irreversible approach to thermal equilibrium by employing methods analogous to those Boltzmann used in kinetic theory. Planck introduced the notion of 'natural' that is maximally disordered radiation which he defined in analogy with Boltzmann's definition of molecular chaos . "Planck calculated the average energy of an oscillator by making assumptions about the entropy of the oscillators that enabled him to derive Wien's law for the blackbody spectrum which originally seemed well supported by the experimental evidence. But by the turn of the century new observations showed systematic deviations from Wien's law for large values of temperature. "Planck in 1900 presented a new energy density distribution formula that agreed closely with observations over the entire spectrum . this expression now known as Planck's law or Planck's formula involves a new constant h later called Planck's constant. To derive this formula Planck calculated the entropy of the oscillators using what Einstein later called 'the Boltzmann principle': S = k log W where S is the entropy of a macroscopic state of the system the probability of which is W and k is 'Boltzmann's constant'. Following Boltzmann Planck took W proportional to the number of 'complexions' or possible microconfigurations of the system corresponding to its state. He calculated this number by dividing the total energy of the state into a finite number of elements of equal magnitude and counting the number of possible ways of distributing these energy elements among the individual oscillators. If the size of the energy elements is set equal to hv where v is the frequency of the oscillators an expression for the entropy of an oscillator results that leads to Planck's formula . "In the 1905 paper Einstein showed that the expression for the volume dependence of the entropy of radiation at a given frequency is similar in form to that of the entropy of an ideal gas. He concluded that 'monochromatic radiation of low density behaves thermodynamically as though it consisted of quanta of energy which are independent of one another' . Einstein opened the paper by pointing out the 'fundamental formal distinction' between current theories of matter in which the energy of a body is represented as a sum over a finite number of degrees of freedom and Maxwell's theory in which the energy is a continuous spatial function having an infinite number of degrees of freedom. He suggested that the inability of Maxwell's theory to give an adequate account of radiation might be remedied by a theory in which radiant energy is distributed discontinuously in space. Einstein formulated 'the light quantum hypothesis' that the energy of a light ray emitted from a point is not continuously distributed over an ever increasing space but consists of a finite number of energy quanta which are localized at points in space which move without dividing and which can only be produced and absorbed as complete units . Einstein asserted that Planck's derivation implicitly assumes quantization of the energies of charged oscillators" Papers pp. 134-142. "In 1905 Einstein could not make sense of Planck's derivation of Planck's law. In fact he seems to have deliberately avoided any reference to Planck's law in his reasoning . The following year Einstein ceased to avoid Planck's law as he discovered a new way to justify Planck's formal steps toward this law. If a resonator of frequency ν can only emit or absorb full light quanta Einstein reasoned then its energy can only be an integral multiple of hν and Planck's characterization of the complexions for a set of resonators receives a dynamical justification. The only remaining difficulty is that Planck's derivation of the relation between the average energy of a resonator and the spectral density of radiation becomes void. Einstein expressed the need of a new derivation based on some quantized dynamics for the interaction between matter and radiation. Ten years elapsed however before he filled the gap" Janssen & Lehner p. 126. In the final section of this paper Einstein gives a new application of his 'heuristic principle' to the explanation of the 'Volta effect' - that when two different metals are placed in contact a potential difference between them is observed.

Zur Theorie der Radiometerkräfte.

Best.-Nr. 72535Braunschweig Friedrich Vierweg & Sohn; Berlin J. Springer 1924. 8vo 22.8 x 15.4 cm. 6 pp. Original printed wrappers. = On the theory of radiometer forces. "The Crookes radiometer also known as a light mill consists of an airtight glass bulb containing a partial vacuum with a set of vanes which are mounted on a spindle inside. The vanes rotate when exposed to light with faster rotation for more intense light providing a quantitative measurement of electromagnetic radiation intensity. The reason for the rotation was a cause of much scientific debate in the ten years following the invention of the device" Wikipedia. James Clerk Maxwell first gave a wrong then a correct explanation. However some subtleties still needed to be solved and in 1924 Albert Einstein had a crack at it "A partial explanation is that gas molecules hitting the warmer side of the vane will pick up some of the heat bouncing off the vane with increased speed. Giving the molecule this extra boost effectively means that a minute pressure is exerted on the vane. The imbalance of this effect between the warmer black side and the cooler silver side means the net pressure on the vane is equivalent to a push on the black side and as a result the vanes spin round with the black side trailing. The problem with this idea is that while the faster moving molecules produce more force they also do a better job of stopping other molecules from reaching the vane so the net force on the vane should be the same. The greater temperature causes a decrease in local density which results in the same force on both sides. Years after this explanation was dismissed Albert Einstein showed that the two pressures do not cancel out exactly at the edges of the vanes because of the temperature difference there. The force predicted by Einstein would be enough to move the vanes but not fast enough" Wikipedia. Contained first paper in: Zeitschrift für Physik volume 271.
