Stamp to front free end-paper and titlepage, otherwise fine and clean. Pp. 633-46. [Entire volume: VIII, 822 pp.]. First printing of Wang's Ph.D thesis on beta decay spectrum under the supervision of Lise Meitner. Wang was one of the initiators of research in China in nuclear physics, cosmic rays and particle physics and figured among the top leaders, pioneers and scientists of the Chinese nuclear deterrent program. Wang (1907 - 1998), a nuclear physicist from China, went in 1930 to study at the University of Berlin in Germany. As soon as he arrived in Berlin, hearing the Bothe report relating the emission of a new type of high-energy neutral radiation which was non-ionizing but even more penetrating than the hardest gamma rays derived from radium, induced by the bombardment of beryllium with ? particles from a radioactive polonium source, therefore wrongly presumed to be gamma rays, Wang first suggested the use of a cloud chamber to study it. Lacking the support of his supervisor Lise Meitner, the experiment was nonetheless conducted one year later by the English physicist James Chadwick, thus discovering a new type of particle, the neutron, allowing him to win the 1935 Nobel Prize in Physics.In 2000, the Chinese Physical Society established five prizes in recognition of five pioneers of modern physics in China. The Wang Ganchang Prize is awarded to physicists in particle physics and inertial confinement fusion.

Vol. 10 of Salmon's extensive 'Modern History' containing information and maps on Italy, Venice, Sicily ect. Salmon’s "Modern History” is an ambitious attempt to provide a comprehensive account of the world’s countries, their histories, and their contemporary states during Salmon’s time and stands as a monumental achievement in the history of 18th-century historiography. His work is a fine example of the Enlightenment's goal for cataloging and comprehending the world, offering a unique snapshot of global perspectives as understood by Europeans in the early modern period. It represents one of the earliest comprehensive attempts to document and analyze the state of nations worldwide.

Stamp to front free end-paper and titlepage, Extremities with light wear. Pp. 169-84. [Entire volume: VII, (1), 846 pp.]. First appearance of Paul Güttinger's important paper which constitute the first derivation of the Hellmann-Feynman formulas.In quantum mechanics, the Hellmann-Feynman theorem relates the derivative of the total energy with respect to a parameter, to the expectation value of the derivative of the Hamiltonian with respect to that same parameter. According to the theorem, once the spatial distribution of the electrons has been determined by solving the Schrödinger equation, all the forces in the system can be calculated using classical electrostatics.

Braunschweig und Berlin, Vieweg & Sohn, Julius Springer, 1921. 8vo. Bound in contemporary half cloth. Stamp to front free end paper. In "Zeitschrift für Physik. Hrasg. von Karl Scheel", vol. 5. Entire volume offered. [Schrödinger's paper:] pp. 163-66. [Entire volume: IV, 449, (1) pp]. First apperance of Schrödinger's paper on isotopy and the Gibb's paradox. "Schrödinger started explicitly from the previous discussion between de Hevesy and Paneth on the one hand, and Fajans on the other, summarizing the results as 'Thermodynamical diversity of isotopes in principle, in spite of their complete or nearly complete chemical replaceability'. Thus far he partially supported the view promoted by Karlsruhe physico-chemist. However, he contradicted a result which Fajans had obtained, stating that the energy set free by mixing or diffusion of the volumes, containing different isotopes of the same chemical element, was proportional to the difference of the respective atomic weights - hence a consequence, it should become arbitrarily small as the mass difference disappeared.
