Éleuthère Mascart
Éleuthère Élie Nicolas Mascart (20 February 1837 – 24 August 1908) was a French physicist. His research focused in optics, electricity, magnetism, and meteorology. Life Mascart was born in Quarouble, Nord. Starting in 1858, he attended the École normale supérieure (rue d'Ulm), earning his '' agrégé-préparateur'' three years later. He acquired his doctoral degree in science in 1864. After serving at various posts in secondary education, in 1868 he moved to the Collège de France to become Henri Victor Regnault's assistant. Mascart was appointed to succeed Régnault as the tenured Régnault chair in 1872, which he held until his death. In 1878 he also became the first director of the Bureau Central Météorologique.

American Philosophical Society
The American Philosophical Society (APS) is an American scholarly organization and learned society founded in 1743 in Philadelphia that promotes knowledge in the humanities and natural sciences through research, professional meetings, publications, source text, library resources, and community outreach. It was founded by the polymath Benjamin Franklin and is considered the first learned society founded in what became the United States.Philosophical Hall, the society's headquarters and a museum, is located just east of Independence Hall in Independence National Historical Park. In 1965, in recognition of the building's history, it was designated a National Historic Landmark. The society has about 1,000 elected members. As of April 2020, 5,710 members had been inducted since its creation. Through research grants, published journals, the American Philosophical Society Museum, an extensive library, and regular meetings, the society supports a variety of disciplines in the humanitie ...

Fizeau Experiment
The Fizeau experiment was carried out by Hippolyte Fizeau in 1851 to measure the relative speeds of light in moving water. Fizeau used a special interferometer arrangement to measure the effect of movement of a medium upon the speed of light. According to the theories prevailing at the time, light traveling through a moving medium would be dragged along by the medium, so that the measured speed of the light would be a simple sum of its speed ''through'' the medium plus the speed ''of'' the medium. Fizeau indeed detected a dragging effect, but the magnitude of the effect that he observed was far lower than expected. When he repeated the experiment with air in place of water he observed no effect. His results seemingly supported the partial aether-drag hypothesis of Augustin-Jean Fresnel, a situation that was disconcerting to most physicists. Over half a century passed before a satisfactory explanation of Fizeau's unexpected measurement was developed with the advent of Albert Ein ...

Roger H
Roger is a masculine given name, and a surname. The given name is derived from the Old French personal names ' and '. These names are of Germanic languages">Germanic origin, derived from the elements ', ''χrōþi'' ("fame", "renown", "honour") and ', ' ("spear", "lance") (Hrōþigēraz). The name was introduced into England by the Normans. In Normandy, the Franks, Frankish name had been reinforced by the Old Norse cognate '. The name introduced into England replaced the Old English cognate '. ''Roger'' became a very common given name during the Middle Ages. A variant form of the given name ''Roger'' that is closer to the name's origin is '' Rodger''. Slang and other uses From up to , Roger was slang for the word "penis". In ''Under Milk Wood'', Dylan Thomas writes "jolly, rodgered" suggesting both the sexual double entendre and the pirate term "Jolly Roger".

Paul Langevin
Paul Langevin (23 January 1872 – 19 December 1946) was a French physicist who developed Langevin dynamics and the Langevin equation. He was one of the founders of the '' Comité de vigilance des intellectuels antifascistes'', an anti-fascist organization created after the 6 February 1934 far right riots. Being a public opponent of fascism in the 1930s resulted in his arrest and being held under house arrest by the Vichy government for most of World War II. Langevin was also president of the Human Rights League (LDH) from 1944 to 1946, having recently joined the French Communist Party. He was a doctoral student of Pierre Curie and later a lover of widowed Marie Curie. He is also known for his two US patents with Constantin Chilowsky in 1916 and 1917 involving ultrasonic submarine detection. He is entombed at the Panthéon. Life Langevin was born in Paris, and studied at the '' École de Physique et Chimie'' and the ''École Normale Supérieure''. He then went to the Univ ...

Cape Mascart
Adelaide Island is a large, mainly ice-covered island, long and wide, lying at the north side of Marguerite Bay off the west coast of the Antarctic Peninsula. The Ginger Islands lie off the southern end. Mount Bodys is the easternmost mountain on Adelaide Island, rising to over 1,220 m. The island lies within the Argentine, British and Chilean Antarctic claims. History Adelaide Island was discovered in 1832 by a British expedition under John Biscoe. The island was first surveyed by the French Antarctic Expedition (1908–1910) under Jean-Baptiste Charcot. According to a contemporary source, the island was named by Biscoe himself in honour of Queen Adelaide of the United Kingdom, who earlier gave her name to the city in Australia. The Island has two bases on it. The old Adelaide Island base (also known as Base T) was set up by the Falkland Islands Dependencies Survey (FIDS), which later became the British Antarctic Survey. The Base was closed due to an unstable skiway and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Léon Brillouin
Léon Nicolas Brillouin (; August 7, 1889 – October 4, 1969) was a French physicist. He made contributions to quantum mechanics, radio wave propagation in the atmosphere, solid-state physics, and information theory. Early life Brillouin was born in Sèvres, near Paris, France. His father, Marcel Brillouin, grandfather, Éleuthère Mascart, and great-grandfather, Charles Briot, were physicists as well. Education From 1908 to 1912, Brillouin studied physics at the École Normale Supérieure, in Paris. From 1911 he studied under Jean Perrin until he left for the Ludwig Maximilian University of Munich (LMU), in 1912. At LMU, he studied theoretical physics with Arnold Sommerfeld. Just a few months before Brillouin's arrival at LMU, Max von Laue had conducted his experiment showing X-ray diffraction in a crystal lattice. In 1913, he went back to France to study at the University of Paris and it was in this year that Niels Bohr submitted his first paper on the Bohr model of ...
