1905réf. 42829Leipzig S. Hirzel 1905. No wrappers. Issued in "Jahrbuch der Radioaktivität und Elekronik" 2. Bd. Heft 3. Hahn's paper: pp. 233-264. Enntire issue: pp. 233-262 = entire "Heft 3". Fine and clean. First printing of this paper which is Hahn's Habilitation paper announcung his discovery of a new element in residues from a Ceylon mineral called Thorianite. He later showed that it is an intermediate disintegration product."Because the sample thorianite was small Ramsay proposed that Hahn confirm Marie Curie's determination of the atomic weight of radium by preparing it in some organic compounds thereby greatly increasing the total amount being examined and calculating the atomic weight from the measured molecular weights. Chance sometimes favors the unprepared mind and Hahn who familiarized himself with only the basic of radioactivity followed the prescribed separationss technique and found himself the discovere of a new radioelement: radiothorium. The explanation was that the material given him came from an ore which contained a large percentage of thorium in addition to the radium. Thus upon completion of the chemical procedure not all the activity was confined in the radium-containg fraction; indeed the nes subsyance in the remainder was several hundred thousand times more active than thorium and ultimately yielded the characteristic one.minute halflife of thorium emanation."DSB VI p. 15. - Weeks Discovery of the Elementsp. 308 ff. unknown

First edition of the first explicit statement of Einstein's energy-mass equation E=mc2.Nearly all descriptions of Einstein's scientific work state that the mass-energy equivalence E=mc2 was first formulated in Einstein's 1907 review paper 'Über das Relativitätsprinzip und die aus demselben gezogenen.' published in 'Jahrbuch der Radioaktivität und Elektronik' see Weil no. 21 and Dictionary of Scientific Biography vol. 4 pp.323 for examples. However in his paper 'Über die von Relativitätsprincip geforderte Trägheit der Energie' the offered paper which predates the former mentioned by six months Einstein gave a clear statement of the mass-energy equivalence E=mc2. See Lanczos: The Einstein Decade pp.149-150 and 153 as well as Volume 2 of 'The Collected Papers of Albert Einstein' pp. 428.Einstein's first paper regarding the relation E=mc2 is his fourth 1905 paper 'Ist die Trägheit eines Körpers von seinem Energieinhalt abhängig'. In this short paper Einstein showed that a body releasing the energy E in the form of radiation will have its mass decreased by E/c2 and concluded that the mass of a body is a measure of its energy content e.g. that all energy has mass. The next time Einstein returns to the subject is in his 1906 paper 'Das Prinzip von der Erhaltung der Schwerpunkts Bewegung und die Trägheit der Energie.'. Here Einstein concluded that one must either ascribe the inertial mass E/c2 to any form of energy E or else give up the fundamental law mechanics regarding conservation of the motion of the center of gravity. Then finally in the 1907 paper 'Über die von Relativitätsprincip geforderte Trägheit der Energie.' the offered paper Einstein makes the decisive step of assuming that all mass has energy. On page 382 Einstein considers the total energy of a moving mass point as the sum of its kinetic energy and its rest energy. In classical mechanics it is most convenient to set the second term to zero but in relativistic mechanics one obtains the simplest expression by setting the rest energy equal to mc2. Einstein then continues to show that this stipulation cannot lead to a contradiction in any relativistic argument. In a footnote on page 382 Einstein states for the first time the equation E=mc2 and mentions that this equation is the expression of the principle of the equivalence of mass and energy - see Volume 2 of 'The Collected Papers of Albert Einstein' pp. 428.The volume contains another paper by Einstein "Bemerkungen zu der Notiz von Hrn.

1920réf. 48726Braunschweig Vieweg & Sohn 1920. Contemp. Hcloth. Stamp on titlepage. In "Zeitschrift für Physik" Bd. 2. IV478 pp. Entire volume offered. Bohr's paper: pp. 423-469. A very faint dampstain to right margins. First edition of this fundamental paper in which Bohr for the first time gives name to a theory which was for the first time used in his work "The quantum theory of line Spectra" from 1918 but now for the first time called "Korrespondenzprincip" The Principle of Correspondence and explained in the offered paper. The principle was introduced "in order to obtain the necessary relation to the ordinary theory of radiation in the limit of slow vibrations we are therefore led directlyto certain conclusions about the probability of transition between two stationary states in this limit.".The "Principle of Correspondence" is the physical priciple that the behaviour of atomic and other systems should approximate to that predicted by classical physics in certain specific circumstances where quantum effects are expected to be unimportent. Bohr used the principle to explain his theory of the hydrogen atom which among other things successfully predicted many features of the spectrum of light emitted by energetic hydrogen atoms. The principle formed an importent component of the early quantum theory of Bohr Sommerfeld and others.Betty Schultz: 17. hardcover

Pp. 1- 155 a. 7 plates.Entire issue offered. Boltzmann's paper: pp. 54-59. Clean and fine. First apperance of an importent paper in which Boltzmann from a mathematical point of view defends atomism. "Throughout his career even in his works on subjects other than kinetic theory Boltzmann was concerned with the mathematical problems arising from the atomic nature of matter. Thus an early paper with the title "Über die Integrale linearer Differentialgleichungen mit periodischcn Koeffizienten" 1868 turned out to be an investigation of the validity of Cauchy’s theorem on this subject which is needed to justify the application of the equations for an elastic continuum to a crystalline solid in which the local properties vary periodically from one atom to the next." DSB. The issue contains an importent paper by JOHANN JOSEPH LOSCHMIDT "Ableitung des Potentiales bewegter elektrischer Massen aus dem Potentiale für die Ruhestand" pp. 7-14 in which he attempted to derive the Weber-Ampère law from that of Coulomb and in accordance with Kirchhoff to derive Ohm’s law from hydrodynamic flow laws analogous to Poiseuille’s law. unknown

1913réf. 45816Leipzig S. Hirzel 1913. 8vo. Orig. printed wrappers no backstrip. Wrappers loose. In "Jahrbuch der Radioaktivität und Elektronik" 10. bd. Heft 1. Pp. 1-138 entire issue offered. Wilson's paper: pp. 34-54 textillustrations showing apparatus and 5 photographic plates showing ionizing by Alpha- Beta- and Röntgen- radiation. Together with the English version - published 1912 in the Proceedings of the Royal Society - this is Wilson's main paper relating "that the track of an ionizing particle might be made visible and photographed by condensing water of the ions which is liberated". The first trails were obtained in 1911 where he submitted a short note of this to the Proceedings. In the offered paper he published the first tracks made by the ionizing particles of alpha beta and Röntgen-rays. This Wilson Cloud-Chamber became an extremely valuable instrument of fundamental research the discovery of the positron in 1932 and the kaon in 1963 were made by using cloud chambers as detectors."But the whole course of the particle appears infinitely more clearly by the method invented by C.T.R. Wilson in 1911 and named after him. The radiation is allowed to enter an expansion-chamber containing a gas saturated with water vapour. A sudden expansion of the chamber cools the gas and cloud-drops are then formed instantly around the ions produced along the tracks of the particles. By suitable illumination these tracks can be made to stand out clearly as if they had been described by luminous projectiles. The "Altmeister" of modern nuclear physics Lord Rutherford once called the Wilson chamber "the most original and wonderful instrument in scientific history"."Thomson Rees Wilson 1869-1959 a Scottish physicist is credited with inventing the cloud chamber. Inspired by sightings of the Brocken spectre while working on the summit of Ben Nevis in 1894 he began to develop expansion chambers for studying cloud formation and optical phenomena in moist air. Very rapidly he discovered that ions could act as centers for water droplet formation in such chambers. He pursued the application of this discovery and perfected the first cloud chamber in 1911. In Wilson's original chamber the air inside the sealed device was saturated with water vapor then a diaphragm is used to expand the air inside the chamber adiabatic expansion. This cools the air and water vapor starts to condense. When an ionizing particle passes through the chamber water vapor condenses on the resulting ions and the trail of the particle is visible in the vapor cloud. Wilson along with Arthur Compton received the Nobel Prize in Physics in 1927 for his work on the cloud chamber. Wikipedia. unknown
