Clean and fine. Punched in inner margins after cords. First printing of this highly importent paper on the MOLECULE FORMATION AS A QUESTION OF ATOMIC STRUCTURE introducing 'Polar Bonds'. - Kossel was awarded the Nobel Prize in Mdicine ! in 1910."The first successfull application of the new electron theory of atomic structure was made by Kossel who explained the nature of inorganic polar bonds. A similar explanation was offered by G.N. Lewis at about the same time and he extended and theory to non polar bonds or covalent links as they came to be called. Langmuir further developed this aspect of the theory. The work of Kossel Lewis and Langmuir.laid the foundations for all later theories of molecular structure."

Max Planck is considered to be the founder of the quantum theory and was awarded the Nobel Prize in Physics in 1918. "Über irreversible Strahlungsvorgänge" is a mathematical description of the electromagnetic radiation emitted from a black-body."Über irreversible Strahlungsvorgänge was published in five parts in the period 1897-1901 the present volume being number 1."With the Kirchhoff-Wien-Boltzmann work as a background Max Planck began his attack on the black-body problem in 1897. He labored under the erroneous impression for some time that Wien's formula was the only one which harmonized with the second law of thermodynamics. The experiments on black-bodies due to Lummer and Pringsheim Rubens and Kurlbaum forced him from that position." Planck Max. Catalogue 258 Interlibrum Vaduz "I had already been struggling with the problem of the equilibrium of matter and radiation for some years without success; I knew the problem is of fundamental significance for Physics." The significance was unparallelled when he in December 1900 delivered a paper entitled "On the Theory of the Energy Distribution Law in the Normal Spectrum" before the German Physical Society which today is considered the birth of quantum physics. The present volume constitutes a precursor to this work. - Akademie No 33 unknown

1829ref. 41607Berlin G. Reimer 1829. 4to. No wrappers. Extracted from "Journal für die reine und angewandte Mathematik. Hrsg. von A.L. Crelle" Bd. 4. - Gauss' paper: pp. 232-35. - Abel's papers: pp. 236-278 and pp. 309-348. First printing of probably Gauss' most importent work in physics by presenting his "Principle of Least Action" which states that the motion of a system of points which are influenced both by each other and by outside conditions is such as to maximize the agreement with free motion given the existent constraint. The work is based on his Potential Theory."In it the present paper Gauss stated that the law of least constraint: the motion of a system departs a little as possible from free motion where departure or constraint is measured by the sum of products of masses times the squares of their deviations from the path of free motion. He presented it merely as a new formulation equivalent to the well-known principle of d'Alembert. This work seems obviously related to the old meditations on least aquares but Gauss wrote to Olbers on 31 January 1829 thai it was inspired by studies of capillarity and other physical problems." Kenneth O. May in DSB.The two papers first printings by Abel book-lenghts memoirs are his last works - he died 1829 and they were published after his death - on the theory of "elliptic functions" the discovery of which he shared with Jacobi. In these papers he mentions also the great discoveries published in his memoir 1826 Memoire sur une proprieté générale d'un classe très-etendu de fonctions transcendentes which was not published until 1841.Together with these 3 memoirs is found a paper by Alexander von Humboldt: "Über die bei verschiedenen Völkern üblichen Systeme von Zahlzeichen und über den Ursprung des Stellenwerthes in den indischen Zahlen" 1829.

1905ref. 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

VIII1000 pp. a. 4 plates. The entire volume offered. Einstein's paper: pp.371-384. Stamps on titlepage Allgemeine Electricitäts-Gesellschaft a. AEG Forschungsinstitut. Internally clean. 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.
