19141199Braunschweig: Friedr. Vieweg & Sohn 1914. 1st Edition. FIRST EDITION FULL VOLUME OF THE FRANCK-HERTZ EXPERIMENT: THE FIRST ELECTRICAL MEASUREMENT TO CLEARLY SHOW THE QUANTUM NATURE OF ATOMS - PROOF OF THE QUANTIZED MODEL OF THE BOHR ATOM & OF PLANCK'S QUANTUM THEORY. Note that this volume includes both the first and second Franck-Hertz experiment. In the first they demonstrate that atoms can only absorb and be excited by specific amounts of energy; in the second experiment performed the same year they demonstrate that the frequency of the light emitted following the collision of electrons with mercury atoms corresponds precisely with the energy lost by the electrons in the collision. Franck and Hertz received the Nobel Prize for this work specifically "for their discovery of the laws governing the impact of an electron upon an atom" Nobel Prize Committee. Of equal import this volume also contains a paper by Einstein in which he uses the light quantum hypothesis to give new derivations of Planck's radiation law and Nernst's third law of thermodynamics. His "proofs introduced the quantum hypothesis" Calaprice The Einstein Almanac 40. In 1914 James Franck and Gustav Hertz were working together in the Physics Institute of Berlin and were "particularly interested in ionization i.e. in the process in which an electron is removed from an atom" The Harvest of a Century" p. 102-103. The experiment they devised now known commonly as the Franck-Hertz experiment is "a vivid illustration of the quantization of energy" that relied on methodology so simple "that it is now carried out regularly by undergraduates. They accelerated electrons through a low-pressure gas of mercury. When the electrons' energy reach the energy of a stationary state of mercury they gave up a quantum of energy to the mercury resulting in a stepwise shape to the curve of current through the apparatus. This demonstrated that atoms could absorb energy only in discrete amounts" Peacock The Quantum Revolution 40. "Franck and Hertz had not only shown for the first time that electrons lose their kinetic energy to mercury atoms in energy quanta but also that these energy quanta are equal to the energy of the light emitted by the same atoms if interpreted with Einstein's light-quantum hypothesis.This was the first experimental determination of Planck's constant not using blackbody radiation" Brandt 103.

192639022Berlin: Das Kunstarchiv Verlag 1926. First edition. Softcover. g. Quarto. 36pp. Original printed wrappers. Catalog published on the occasion of an exhibition of paintings and drawings by George Grosz held during the Spring of 1926 in Berlin at the Galerie Alfred Flechtheim. This catalog features 24 duo-tone and b/w photographic reproductions. Includes a poem by Gottfried Benn and four essay on the artist and his work by Carl Einstein Marc Neven Max Herrmann and Florent Fels. Some age-wear and moderate soiling on wrappers. Upper corners bumped thus slightly affecting pages throughout. Text in German gothic script with one of the four essays in French. Wrappers in overall good- to good interior in good to very good condition. Alfred Flechtheim 1878-1937 was a German art dealer art collector journalist and publisher. Flechtheim appeared in the art world shortly after 1900 with a collection of paintings by Vincent van Gogh and Paul Cézanne; French Avant garde early works of Pablo Picasso Georges Braque and André Derain; paintings of Wassily Kandinsky Maurice de Vlaminck Alexej von Jawlensky Gabriele Münter and the Rhein Expressionists Heinrich Campendonk August Macke Heinrich Nauen de and Paul Adolf Seehaus de. Flechtheim opened his first gallery in Düsseldorf in 1913 followed by galleries in Berlin Frankfurt Cologne and Vienna. Flechtheim served in the German Army during World War I but not at the front. His art business collapsed during the war but he re-opened in Düsseldorf in 1919. In 1921 he founded "Der Querschnitt" the Cross Section a cultural magazine. Legendary glamorous parties in Flechtheim's gallery overflowed with the glitterati of the new Berlin: movie stars titans of finance prizefighters and artists of every stripe. As Hitler rose to power in the late 1920s and early 1930s Flechtheim became a bête noire because of the art he espoused and championed. In 1933 Sturmabteilung men broke up an auction of Flechtheim's paintings. The Nazis aryanized Flechtheim's gallery as they would many other Jewish businesses and turned it over to Flechtheim's business manager Alex Vömel. After the war former party member Vömel said he didn't even remember who Flechtheim was. The Nazis seized and sold off Flechtheim's private collection as well as the contents of his gallery. Emigration and Death Six months after the Nazis came to power in 1933 Flechtheim penniless fled to Paris and tried to find work with his former business partner Daniel-Henry Kahnweiler. Flechtheim subsequently organized exhibits in London of the paintings of exiled German artists. In London Flechtheim slipped on a patch of ice was taken to a hospital punctured his leg on a rusty nail in his hospital bed developed septicemia leading to amputation of his leg and died.
