He was an honorary doctor of the universities of Warsaw, Bucharest, Athens, Lausanne, Quebec, and Brussels, and a member of eighteen foreign academies in Europe, India, and the United States. 1892–1987, French physicist, noted for his research in quantum mechanics and his development of wave mechanics: Nobel prize for physics 1929 2. Paris: Albin Michel, 1960. De Broglie died of natural causes on March 19, 1987, at the age of ninety-four. Singapore and River Edge, NJ: World Scientific, 2002. Perhaps because he was not inclined to encourage an interactive atmosphere in his lectures, he had no noted record of guiding young research students. In 1919, after what he considered to be six wasted years in uniform, de Broglie returned to his scientific studies at his brother's laboratory. “La découverte des ondes de matière.” In La découverte des ondes de matière: colloque organisé à l’occasion du centenaire de la naissance de Louis de Broglie, 16–17 Juin 1992, edited by Académie des sciences, 79–92. Paris: Lavoisier, 1994. In order to reach an audience wider than the limited readership of the Comptes rendus, de Broglie arranged the publication of a summary of his results in Nature(October 1923); and a fairly complete account of his three communications appeared in the Philosophical Magazine(February 1924). Wave Theory of Matter. Recherches d’un demi-siècle. Paris: Gauthier-Villars, 1956. The House of Broglie is a noble French family, with his father’s death in 1906, his older brother Maurice became the 6th Ducde Broglie. De Broglie was elected a member of the Academy of Sciences in 1933 (section des sciences mécaniques), and was elected its permanent secretary in 1942 (division des sciences mathématiques; he resigned this charge in 1975). “Einstein and the Wave-Particle Duality.” Natural Philosopher 3 (1964): 3–49. He was born in Dieppe, Seine-Maritime. Yet even the war did not take the young scientist away from the country where he would spend his entire life; for its duration, de Broglie served with the French Engineers at the wireless station under the Eiffel Tower.

These dynamics were non-classical, owing to the fundamental fact that the particle was coupled to the wave via the guiding mechanism which related the particle’s velocity to the gradient of the wave phase. With the brothers Maurice and especially Louis, it added to its famous representatives (among them three state marshals) two world-rank physicists of the twentieth century. His family, from a noble Italian (Piedmont) lineage, the Broglia, settled in France when Francesco Maria Broglia followed Cardinal Jules Mazarin in the seventeenth century.

In 1928, de Broglie was appointed professor of theoretical physics at the University of Paris's Faculty of Science. His work was extended into a full-fledged wave mechanics by Erwin Schrödinger and thus contributed to the creation of quantum mechanics. □. Radio i u Institutu Henri Poincaré (od 1932). The brothers frequently discussed x rays, and their dual nature (both wavelike and particle-like behavior) suggested to Louis that this same particle-wave duality might also apply to particles such as electrons. He obtained his Licence ès sciences in 1913. "Broglie, Louis Victor De (1892-1987) This was, however, increasingly perceived as a marginal research program, even in his own country, where quantum theoreticians preferred to stick to more mainstream physics, less fundamental and closer to the wealth of new experimental data emerging in the 1950s. . Radiant energy or light had been demonstrated to exhibit properties associated with particles as well as their well-documented wave-like characteristics. 2 citations les plus célèbres de Louis Victor de Broglie issues de livres - paroles - discours et entretiens. They were, as he dubbed them, “fictitious.” However, in the months following his PhD, de Broglie started to explore the consequences of his wave-particle model for the problem of the interaction of light with matter. Maurice had no surviving children, while Louis died unmarried. (b. Paris, France, 23 January 1872; d. Paris, 19 December 1946) He served with his father, François-Marie, 1st duc de Broglie, at Parma and Guastalla, and in 1734 obtained a colonelcy.

About Louis Victor de Broglie, Nobel Prize in Physics, 1929 Louis-Victor-Pierre-Raymond, 7th duc de Broglie (August 15, 1892 – March 19, 1987) was a French physicist and a Nobel laureate in Physics, 1929 "for his discovery of the wave nature of electrons". Louis Victor de Broglie, a theoretical physicist and member of the French nobility, is best known as the father of wave mechanics, a far-reaching achievement that significantly changed modern physics. However, he introduced in his paper, most significantly, the idea of a light quantum with a very small, but nonvanishing, mass.Apparently, de Broglie was guided by his desire to interpret the continuously varying energies of the light quanta as corresponding to the various (sublight) velocities these quanta could then have. “Louis de Broglie: la grandeur et la solitude.” LaRecherche 245 (1992): 918–923. However, Louis obtained his own interpretation within a much broader scheme of a general wave-particle duality, using relativity theory as a guide—a theory that he had ample time to ponder following Langevin’s outstanding teaching of the topic in the years 1920–1922. . Louis also became interested in science and decided to pursue a degree in theoretical physics . . Chemistry: Foundations and Applications. (January 12, 2021). "Broglie, Louis (Victor Pierre Raymond) De Cline, Barbara Lovett, Men Who Made a New Physics, University of Chicago Press, 1987. Although he saw his ideas extended and vindicated, his conception of the meaning of his research and how it should be continued was increasingly at odds with the views of his peers. botany, medicine.

Certitudes et incertitudes de la science. He thought of each pair as consisting of a singular solution, with the singularity identified with the particle, while the corresponding continuous regular solution (the only one considered by Schrödinger) was interpreted as conveying solely statistical information. In Germany, a summary of his communications was published in the Physikalische Berichte(1924). “Why Was It Schrödinger Who Developed de Broglie’s Ideas?” Historical Studies in the Physical Sciences 1 (1969): 291–314. After a brief diplomatic career at Madrid and Rome, the revolution of 1848 caused him to withdraw from public life and devote himself to literature. Louis de Broglie the son of Victor, 5th Duc de Broglie, was born at Dieppe on August 15, 1892. P rince Louis-Victor de Broglie of the French Academy, Permanent Secretary of the Academy of Sciences, and Professor at the Faculty of Sciences at Paris University, was born at Dieppe (Seine Inférieure) on 15th August, 1892, the son of Victor, Duc de Broglie and Pauline d’Armaillé. Pour chaque citation, la source est donnée. Victor de Broglie (28 November 1785 – 25 January 1870) was Prime Minister of France from 12 March 1835 to 22 February 1836, succeeding Edouard Mortier and preceding Adolphe Thiers. 4 Jules x second… avec Victor de Broglie (1785-1870) comme Éditeur scientifique Rapport fait à la Chambre par M. le duc de Broglie, au nom d'une Commission spéciale chargée de l'examen du projet de loi sur la régence (1843) Discours prononcé par M. le duc de Broglie, à l'occasion du décès de M. le maréchal Mis Maison (1842) : . Wave mechanics describes the behavior of matter, including subatomic particles such as electrons, with respect to their wave characteristics. Wave characteristics, however, are detectable only at the atomic level, whereas the classical, ballistic properties of matter are apparent at larger scales. The ensuing events, which led rapidly to the final formulation of quantum mechanics in 1926–1927, did not include the active participation of Louis de Broglie. Retrieved January 12, 2021 from Encyclopedia.com: https://www.encyclopedia.com/science/dictionaries-thesauruses-pictures-and-press-releases/broglie-louis-victor-pierre-raymond-de. Paris: Lavoisier, 1994. At the atomic level, however, matter waves are relatively larger and their effects become more obvious. American physicist Albert Einstein appreciated the significant of de Broglie's theory; de Broglie sent Einstein a copy of his thesis on the advice of his professors at the Sorbonne, who believed themselves not fully qualified to judge it. In his doctoral dissertation in 1924, Louis de Broglie developed the equation λ = h/mυ, which predicts that the wavelength λ of a particle is inversely proportional to its mass m and velocity υ where h is Planck's constant.✷ The wavelength associated with a submicroscopic object—an electron, for example—is large relative to the size of the object and is therefore significant in describing its behavior, whereas the wavelength associated with a macroscopic object—a basketball, for example—is negligibly small relative to its size, and therefore the wavelike behavior of such an object is unnoticeable. Victor-François de Broglie) accusé de conspirer avec les ennemis du dehors ; mais les désavoeux qu'il reçut du maréchal rendirent vains ses courageux efforts. He also served as Perpetual Secretary of the Académie des sciences, France.
