Paperback. Condizione: New. Print on Demand. This foundational scientific text details the author's early research on the propagation of Roentgen rays, commonly known as X-rays, and the secondary rays derived from them. The author's experiments, conducted in the late 19th century, significantly advanced the understanding of the nature of these newly discovered rays. The author describes experiments using a series of slits and grids to study the propagation of X-rays. Through these experiments, the author demonstrates that X-rays exhibit properties distinct from visible light. This groundbreaking work laid the groundwork for future research on X-rays and their applications, which have revolutionized medical imaging and other fields. The author's detailed observations and analysis provide valuable insights into the fundamental properties of X-rays. This book remains an essential reference for researchers and historians interested in the early development of X-ray technology and the understanding of radiation physics. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.

Hardcover. Condizione: Good. Interesting Academic and Pedagogical Connections Between Four Leading French Physicists, Two Signed Presentations From the Library of Maurice de Brolgie Sammelband of the theses of Leopold Brizard, Georges Sagnac, Paul Langevin, and Eugene Bloch. Two signed presentations. Included in this single volume: (1) Leopold BRIZARD, "Recherches sur la réduction des composés nitrosés deruthénium et de l osmium" (1902). Inscribed by Brizard to Maurice de Broglie. Paris: Gauthier-Villars, 1900, 75pp. [++] (2) Georges SAGNAC, (1869-1928): "De l optique des rayons de Röntgen et des rayons secondaires qui en dérivent". (1900). Thesis for the Universite de Paris, Gauthier Villars, 1900, 74pp. "From 1896, the year following Röntgen's discovery, to 1900 Sagnac studied the radiations produced by X-rays. He observed that secondary radiation is produced when X-rays fall in heavier metals. He showed that this radiation contained secondary X-rays (of lower frequency than the original X-rays) and negatively charged rays. He suggested that it was through the action of the negative rays that X-rays produce ionization in air" (DSB XII: 69-70) [++] (3) Paul LANGEVIN. (1872-1946)  "Recherches sur les gaz ionisés", Paris, Gauthier, Thesis for the Universite de Paris, 1902, 207pp. Inscribed by Langevin to Brizard, "To my comrade. Cordial memories, P. Langevin." [++] (4) Eugene BLOCH, (1878-1944):  "Recherches sur la conductibilité électrique de l air produite par le phosphore et sur les gaz récemment préparés". Gauthier Villars, Paris, 1904, 125pp. [++] 9.5"x 6", pagination: 74,(4);166,(2);(6),207,(2),125,(3)pp. Cloth-backed marbled boards; leather spine label (mostly rubbed away). Front hinge is sprung but attached. The whole is printed on modest-quality paper which is somewhat browned. Overall, a GOOD copy (4-5/10 or so, "10" being "new"). [++] A short explanation of the connections among these four+ physicists. Brizard signs his copy to Maurice de Broglie (1875-1960) , who was his teacher; Brizard winds up being Maurice's son Louis de Broglie's (1892-1987, Nobel 1929) teacher at Toulin. Then Paul Langevin, advisor and teacher to Louis de Broglie affectionately signs his paper to his teacher Brizard. ("Langevin advised de Broglie, whose groundbreaking dissertation proposed matter waves, forming the basis of quantum mechanics, a concept Langevin initially found astonishing but vital, connecting to modern ideas like pilot-wave theories and Langevin-type dynamics for quantum systems."--Wiki.) [++] Then there's the connection between Georges Sagnac and Eugene Bloch (Bloch being a student and assistant to Langevin for his lab work on gas discharges): "Georges Sagnac and Paul Langevin were known for their intertwined, yet initially conflicting, interpretations of the Sagnac effect. Sagnac discovered the effect in 1913, while Langevin provided its accepted theoretical explanation within the framework of relativity in 1921."--Wiki So there are a number of major and minor connections between these four plus their connections to the de Broglies.

[Entire issue: Pp. 665-736" pp. 1357-1492]. First appearance of Sagnac two seminal papers which together constitutes the first interferometry experiment aimed at observing the correlation of angular velocity and phase showing that if a beam of light is split and sent in two opposite directions around a closed path on a revolving platform with mirrors on its perimeter, and then the beams are recombined, they will exhibit interference effects. From this result Sagnac concluded that light propagates at a speed independent of the speed of the source. The motion of the earth through space had no apparent effect on the speed of the light beam, no matter how the platform was turned."Sagnac interpreted the shift in the position of the interference fringes in terms of an "ether wind" that gave the light beams traveling in opposite directions different velocities. He was convinced that the phenomenon observed with the rotating interferometer demonstrated the existence of an immobile ether. Sagnac later tried to develop a theory of electrodynamics that would retain classical ideas of space, time, and ether by analyzing the propagation of energy statistically and separately from the propagation of motion. He retained a lifelong dislike for relativity, and in 1923 he interpreted some observations of stellar color shift as being due to an ether wind, rather than as supporting the general theory of relativity.The results of Sagnac's interferometer experiments were used by some scientists in France as an argument against the theory of relativity. As late as 1937 Dufour and Prunier repeated the experiment in a modified form for that purpose. The experiment does not contradict relativity theory in any way, however, and in 1921 and 1937 Langevin responded with an explanation of how it should be interpreted." (DSB).

Georges M.M. Sagnac (1869-1928) "studied mainly the radiation produced by X rays and the optics of interference. He is remembered today primarily for his design of a rotating interferometer and for the experimental results it provided. He was very interested in the theoretical analysis of optics of moving systems; his approach was classical, and he interpreted the results of optical experiments as contradicting Einstein's theory relativity. Sagnac's earliest research (and the subject of his dissertation) was motivated by the newly observed X rays. From 1896, the year following Röntgen's discovery, to 1900 Sagnac studied the radiations produced by X rays. He observed that secondary radiation is produced when X rays fall in heavier metals. He showed that this radiation contained secondary X rays (of lower frequency than the original x rays) and negatively charged rays. He suggested that it was through the action of the negative rays that X rays produce ionization in air." Sigalia Dostrovsky, DSB XII, pp.69-70.
