Henri Becquerel
Antoine Henri Becquerel ( ; ; 15 December 1852 – 25 August 1908) was a French nuclear physicist who shared the 1903 Nobel Prize in Physics with Marie and Pierre Curie for his discovery of radioactivity. Biography Family and education Becquerel was born in Paris, France, into a wealthy family which produced four generations of notable physicists, including Becquerel's grandfather ( Antoine César Becquerel), father ( Edmond Becquerel), and son ( Jean Becquerel). Henri started off his education by attending the Lycée Louis-le-Grand school, a prep school in Paris. He studied engineering at the École polytechnique and the École des ponts et chaussées. Career Becquerel's earliest works centered on the subject of his doctoral thesis: the plane polarization of light, with the phenomenon of phosphorescence and absorption of light by crystals. Becquerel was awarded a Doctor of Science in 1888. Early in his career, Becquerel also studied the Earth's magnetic field. Becqu ...

Paul Nadar
Paul Nadar (8 February 1856 – 1 September 1939) was a French photographer and the son of Nadar, who was also a photographer, and the grandson of Victor Tournachon, who was a printer and bookseller. Life Nadar was born on 8 February 1856 in Paris. He appointed by his father to be manager of the latter's studio in Paris 1874. The two men had a difficult relationship, being estranged for a period, but later collaborated on the world's first photo interview – Nadar senior conducting the interview while Paul took photographs — of Michel-Eugène Chevreul. As of 1 April 1895, his father turned over the Paris Nadar Studio to Paul. His father moved to Marseille, returning to Paris 3 January 1909. The older Nadar died on 20 March 1910, aged 89. The studio continued under the direction of Paul Nadar. Paul died on 1 September 1939 in Paris.

Plane Polarization
In electrodynamics, linear polarization or plane polarization of electromagnetic radiation is a confinement of the electric field vector or magnetic field vector to a given plane along the direction of propagation. The term ''linear polarization'' (French: ''polarisation rectiligne'') was coined by Augustin-Jean Fresnel in 1822.A. Fresnel, "Mémoire sur la double réfraction que les rayons lumineux éprouvent en traversant les aiguilles de cristal de roche suivant les directions parallèles à l'axe", read 9 December 1822; printed in H. de Senarmont, E. Verdet, and L. Fresnel (eds.), ''Oeuvres complètes d'Augustin Fresnel'', vol. 1 (1866), pp.731–51; translated as "Memoir on the double refraction that light rays undergo in traversing the needles of quartz in the directions parallel to the axis", , 2021 (open access); §9.

Doctoral
A doctorate (from Latin ''doctor'', meaning "teacher") or doctoral degree is a postgraduate academic degree awarded by universities and some other educational institutions, derived from the ancient formalism '' licentia docendi'' ("licence to teach"). In most countries, a research degree qualifies the holder to teach at university level in the degree's field or work in a specific profession. There are a number of doctoral degrees; the most common is the Doctor of Philosophy (PhD), awarded in many different fields, ranging from the humanities to scientific disciplines. Many universities also award honorary doctorates to individuals deemed worthy of special recognition, either for scholarly work or other contributions to the university or society. History Middle Ages The term ''doctor'' derives from Latin, meaning "teacher" or "instructor". The doctorate (Latin: ''doctoratus'') appeared in medieval Europe as a license to teach Latin (''licentia docendi'') at a university. Its root ...

Portrait D'Antoine-César Becquerel
A portrait is a painting, photograph, sculpture, or other artistic representation of a person, in which the face is always predominant. In arts, a portrait may be represented as half body and even full body. If the subject in full body better represents personality and mood, this type of presentation may be chosen. The intent is to display the likeness, personality, and even the mood of the person. For this reason, in photography a portrait is generally not a snapshot, but a composed image of a person in a still position. A portrait often shows a person looking directly at the painter or photographer, to most successfully engage the subject with the viewer, but portrait may be represented as a profile (from aside) and 3/4. History Prehistorical portraiture Plastered human skulls were reconstructed human skulls that were made in the ancient Levant between 9000 and 6000 BC in the Pre-Pottery Neolithic B period. They represent some of the oldest forms of art in the Middle Eas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
École Nationale Des Ponts Et Chaussées
École nationale des ponts et chaussées (; ; abbr. ENPC), also nicknamed Ponts (), formerly known as École des Ponts ParisTech (), is a grande école in the field of science, engineering and technology, of the Polytechnic Institute of Paris, a public research university. Founded in 1747 by Daniel-Charles Trudaine, it is one of the oldest and one of the most prestigious French '' Grandes Écoles''. Historically, its primary mission has been to train engineering officials and civil engineers but the school now offers a wide-ranging education including computer science, applied mathematics, civil engineering, mechanics, finance, economics, innovation, urban studies, environment and transport engineering. École des Ponts is today largely international: 43% of its students obtain a double degree abroad, and 30% of an ''ingénieur'' cohort is foreign. It is headquartered in Marne-la-Vallée (suburb of Paris), France, and was a founding member of ParisTech (Paris Institute of Techn ...

Nuclear Physicist
Nuclear physics is the field of physics that studies atomic nuclei and their constituents and interactions, in addition to the study of other forms of nuclear matter. Nuclear physics should not be confused with atomic physics, which studies the atom as a whole, including its electrons. Discoveries in nuclear physics have led to applications in many fields such as nuclear power, nuclear weapons, nuclear medicine and magnetic resonance imaging, industrial and agricultural isotopes, ion implantation in materials engineering, and radiocarbon dating in geology and archaeology. Such applications are studied in the field of nuclear engineering. Particle physics evolved out of nuclear physics and the two fields are typically taught in close association. Nuclear astrophysics, the application of nuclear physics to astrophysics, is crucial in explaining the inner workings of stars and the origin of the chemical elements.

Dictionary
A dictionary is a listing of lexemes from the lexicon of one or more specific languages, often arranged Alphabetical order, alphabetically (or by Semitic root, consonantal root for Semitic languages or radical-and-stroke sorting, radical and stroke for Logogram, logographic languages), which may include information on definitions, usage, etymologies, pronunciations, Bilingual dictionary, translation, etc.Webster's New World College Dictionary, Fourth Edition, 2002 It is a Lexicography, lexicographical reference that shows inter-relationships among the data. A broad distinction is made between general and specialized dictionaries. Specialized dictionaries include words in specialist fields, rather than a comprehensive range of words in the language. Lexical items that describe concepts in specific fields are usually called terms instead of words, although there is no consensus whether lexicology and terminology are two different fields of study. In theory, general dictionarie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

National Museum Of Natural History, France
The French National Museum of Natural History ( ; abbr. MNHN) is the national natural history museum of France and a of higher education part of Sorbonne University. The main museum, with four galleries, is located in Paris, France, within the Jardin des Plantes on the left bank of the River Seine. It was formally founded in 1793, during the French Revolution, but was begun even earlier in 1635 as the royal garden of medicinal plants. The museum now has 14 sites throughout France. Since the 2014 reform, it has been headed by a chairman, assisted by deputy managing directors. The Museum has a staff of approximately 2,350 members, including six hundred researchers. It is a member of the national network of naturalist collections (RECOLNAT).
