‎ Edition originale. Charles Nordmann (1881-1940) astronome à l'Observatoire de Nice a été un précurseur de la radioastronomie. Il chercha à détecter les ondes radio émises par le Soleil. Il mena son expérience sur le glacier des Bossons, au Mont Blanc à 3100 mètres d'altitude, au mois de septembre 1901. Malheureusement il effectua ces mesures pendant une période d'activité solaire minimum, et les résultats furent négatifs. Dans sa thèse, soutenue en 1903, il décrivait l'expérience négative du Mont Blanc, tout en considérant comme "infiniment probable l'émission par le Soleil d'ondes électriques". Il faudra attendre 1942, pour que cela soit prouvé. Illustré par 16 figures intercalées dans le texte. Thèse présentée à la Faculté des Sciences de Paris pour obtenir le grade de docteur es sciences physiques. Soutenues le 13 juin 1903 devant la Commission d'Examen, Henri Poincaré président. Envoi autographe signé : "A Monsieur Lippmann, membre de l'Institut et du Bureau des Longitudes, Hommage de mon profond respect. Ch. Nordmann." Gabriel Lippmann (1845-1921) a été lauréat du prix Nobel de physique de 1908 pour sa méthode de reproduction des couleurs en photographie, basée sur le phénomène d'interférence. Le dos a été renforcé, le coin inférieur de la couverture a été déchiré et manque. /// In-4 de (4), 148, (4) pp. Broché, couverture imprimée. //// First edition. Charles Nordmann (1881-1940), an astronomer at the Nice Observatory, was a pioneer in radio astronomy. He sought to detect radio waves emitted by the Sun. He conducted his experiment on the Bossons glacier, on Mont Blanc at an altitude of 3,100 meters, in September 1901. Unfortunately, he took his measurements during a period of minimal solar activity, and the results were negative. In his thesis, defended in 1903, he described the negative results of the Mont Blanc experiment, while considering it infinitely probable that the Sun emits electric waves. It was not until 1942 that this was finally proven. Illustrated with 16 engravings in text. Thesis presented to the Faculty of Sciences of Paris to obtain the degree of Doctor of Physical Sciences. Presented on June 13, 1903, before the Examination Commission, chaired by Henri Poincaré. Inscribed copy : "To Mr. Lippmann, member of the Institute and the Bureau des Longitudes, with my deepest respect. Ch. Nordmann." Gabriel Lippmann (1845-1921) was awarded the Nobel Prize in Physics in 1908 for his method of reproducing colors in photography, based on the phenomenon of interference. The spine has been reinforced, the lower corner of the cover has been torn and is missing. /// PLUS DE PHOTOS SUR WWW.LATUDE.NET‎
