Biography

De Broglie was born in Dieppe, Seine-Maritime, younger son of Victor, 5th duc de Broglie and a descendant of Madame de Staël. Dieppe is a town and commune in the Seine-Maritime department and Haute-Normandie region of France. Seine-Maritime is a French department in Normandy. Before 1955 it was known as Seine-Inférieure. Louis-Alphonse-Victor 5th duc de Broglie ( 30 October 1846 &ndash 26 August 1906) was a French Aristocrat. Baronne Anne Louise Germaine de Staël-Holstein ( née Necker ( April 22, 1766 &ndash July 14, 1817) (stal commonly known as In 1960, upon the death without heir of his older brother, Maurice, 6th duc de Broglie, also a physicist, he became the 7th duc de Broglie. Louis-César-Victor-Maurice 6th duc de Broglie, generally known as Maurice de Broglie (27 April 1875&ndash14 July 1960 was a French Physicist. Disambiguation For the physicist see Louis de Broglie Did you want to research the De Broglie hypothesis ? The title of He never married. When he died in Louveciennes, he was succeeded as duke by a distant cousin, Victor-François, 8th duc de Broglie. Louveciennes is a village and commune in the Yvelines département, in France, in the western suburbs of Paris, between A duke is a member of the Nobility, historically of highest rank below the Sovereign, and historically controlled a Duchy or a Dukedom Victor-François Marie Léon 8th duc de Broglie (born 25 March 1949, Paris) is a French Aristocrat and current holder of the title

De Broglie had originally intended a career as a humanist, and received his first degree in history. The humanities are academic disciplines which study the Human condition, using methods that are primarily Analytic, Critical, or Speculative History is the study of the past particularly the written record Those who study history as a Profession are called Historians Etymology Afterwards, though, he turned his attention toward mathematics and physics. With the outbreak of the First World War in 1914, he offered his services to the army in the development of radio communications. World War I (abbreviated WWI; also known as the First World War, the Great War, and the War to End All Radio is the transmission of signals by Modulation of electromagnetic waves with frequencies below those of visible Light.

Career

Unlike his brother Maurice, who was primarily an experimental physicist, de Broglie had the mind of a theorist. His 1924 doctoral thesis, Recherches sur la théorie des quanta (Research on Quantum Theory), introduced his theory of electron waves. This included the wave-particle duality theory of matter, based on the work of Albert Einstein and Planck. In Physics and Chemistry, wave–particle duality is the concept that all Matter and Energy exhibits both Wave -like and Albert Einstein ( German: ˈalbɐt ˈaɪ̯nʃtaɪ̯n; English: ˈælbɝt ˈaɪnstaɪn (14 March 1879 – 18 April 1955 was a German -born theoretical This research culminated in the de Broglie hypothesis stating that any moving particle or object had an associated wave. In Physics, the de Broglie hypothesis (pronounced /brœj/ as French breuil close to "broy" is the statement that all Matter (any object has a Wave De Broglie thus created a new field in physics, the mécanique ondulatoire, or wave mechanics, uniting the physics of light and matter. For this he won the Nobel Prize in Physics in 1929. The Nobel Prize in Physics (Nobelpriset i fysik is awarded once a year by the Royal Swedish Academy of Sciences. Among the applications of this work has been the development of electron microscopes to get much better image resolution than optical ones, because of shorter wavelengths of electrons compared with photon. An electron microscope is a type of Microscope that uses Electrons to illuminate a specimen and create an enlarged image In Physics, the photon is the Elementary particle responsible for electromagnetic phenomena

In his later career, de Broglie worked to develop a causal explanation of wave mechanics, in opposition to the wholly probabilistic models which dominate quantum mechanical theory. Causality describes the relationship between Causes and Effects is fundamental to all natural Science, especially Physics, and has a basis in Probability is the likelihood or chance that something is the case or will happen Quantum mechanics is the study of mechanical systems whose dimensions are close to the Atomic scale such as Molecules Atoms Electrons Today, this explanation is known as the de Broglie-Bohm theory, since it was refined by David Bohm in the 1950s. The Bohm interpretation of Quantum mechanics, sometimes called Bohmian mechanics, the ontological interpretation, or the causal interpretation David Joseph Bohm ( December 20 1917, Wilkes-Barre Pennsylvania – October 27 1992, London) was an American

In addition to strictly scientific work, de Broglie thought and wrote about the philosophy of science, including the value of modern scientific discoveries. Philosophy of science is the study of assumptions foundations and implications of Science.

De Broglie became a member of the Académie des sciences in 1933, and was the academy's perpetual secretary from 1942. The French Academy of Sciences ( French: Académie des sciences) is a Learned society, founded in 1666 by Louis XIV at the On 12 October 1944, he was elected to the Académie française, replacing mathematician Émile Picard. L'Académie française, or the French Academy, is the pre-eminent French learned body on matters pertaining to the French language. Charles Émile Picard (usually referred to simply as Émile Picard) ( July 24, 1856 - December 12, 1941) was a leading French Because of the deaths and imprisonments of Académie members during the occupation and other effects of the war, the Académie was unable to meet the quorum of twenty members for his election; due to the exceptional circumstances, however, his unanimous election by the seventeen members present was accepted. In an event unique in the history of the Académie, he was received as a member by his own brother Maurice, who had been elected in 1934. History is the study of the past particularly the written record Those who study history as a Profession are called Historians Etymology UNESCO awarded him the first Kalinga Prize in 1952 for his work in popularizing scientific knowledge, and he was elected a Fellow of the Royal Society on 23 April 1953. United Nations Educational Scientific and Cultural Organization ( UNESCO) is a specialized agency of the United Nations established on November 16 The Kalinga Prize for the Popularization of Science is an Award given by UNESCO for exceptional skill in presenting scientific ideas to lay people. The Royal Society of London for the Improvement of Natural Knowledge, known simply as The Royal Society, is a Learned society for science that was founded in 1660 In 1961 he received the title of Knight of the Grand Cross in the Légion d'honneur. De Broglie was awarded a post as counselor to the French High Commission of Atomic Energy in 1945 for his efforts to bring industry and science closer together. He established a center for applied mechanics at the Henri Poincaré Institute, where research into optics, cybernetics, and atomic energy were carried out. The Institut Henri Poincaré is a mathematical institute in Paris which has established itself over its eighty year history as an important meeting place for French and international He inspired the formation of the International Academy of Quantum Molecular Science and was an early member. The International Academy of Quantum Molecular Science is an international scientific Learned society covering all applications of quantum theory to Chemistry [1]

Note on pronunciation

Note: in French "de Broglie" is pronounced [də bʁœj], which sounds close to "de Broy". French ( français,) is a Romance language spoken around the world by 118 million people as a native language and by about 180 to 260 million people This is an alteration of the Italian pronunciation of "gl" (sound like "ll"); the original name was "Broglia", and was gallicized in 1654. Italian ( or lingua italiana) is a Romance language spoken by about 63 million people as a First language, primarily in Italy. [1]
