Évry Schatzman
Evry Léon Schatzman (16 September 1920 – 25 April 2010) was a French scientist hailed as "the father of modern French astrophysics". Background His father, Benjamin Schatzman, was a dentist born in Tulcea, Romania, and emigrated at a young age with his family to Palestine. Schatzman began his studies at the École normale supérieure in November 1939. After the German invasion of France, Schatzman, who was Jewish, fled occupied France, arriving in Lyon in January 1942. He worked there for a year and then moved to Haute-Provence Observatory where he hid under the pseudonym Antoine Emile Louis Sellier. Career He was appointed by the Centre national de la recherche scientifique (CNRS) in autumn 1945 and received his doctorate in March 1946. He taught at Princeton University and the Copenhagen Observatory. He his mentored during his year at Princeton by Lyman Spitzer and Martin Schwarzschild and works with Bengt Strömgren in Copenhagen. He started teaching at the University o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neuilly-sur-Seine
Neuilly-sur-Seine (; 'Neuilly-on-Seine'), also known simply as Neuilly, is an urban Communes of France, commune in the Hauts-de-Seine Departments of France, department just west of Paris in France. Immediately adjacent to the city, north of the Bois de Boulogne, the area is composed of mostly select residential neighbourhoods, as well as many corporate headquarters and a handful of foreign embassies. One of the most affluent areas of France, it is the wealthiest and most expensive suburb of Paris. Together with the 16th arrondissement of Paris, 16th and 7th arrondissement of Paris, the town of Neuilly-sur-Seine forms the most affluent residential area in France. , it is the commune with the fourth highest median per capita income (€52,570 per year) in France. History Originally, Pont de Neuilly was a small hamlet under the jurisdiction of Villiers, a larger settlement mentioned in medieval sources as early as 832 and now absorbed by the commune of Levallois-Perret. It was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centre National De La Recherche Scientifique
The French National Centre for Scientific Research (, , CNRS) is the French state research organisation and is the largest fundamental science agency in Europe. In 2016, it employed 31,637 staff, including 11,137 tenured researchers, 13,415 engineers and technical staff, and 7,085 contractual workers. It is headquartered in Paris and has administrative offices in Brussels, Beijing, Tokyo, Singapore, Washington, D.C., Bonn, Moscow, Tunis, Johannesburg, Santiago de Chile, Israel, and New Delhi. Organization The CNRS operates on the basis of research units, which are of two kinds: "proper units" (UPRs) are operated solely by the CNRS, and Joint Research Units (UMRs – ) are run in association with other institutions, such as universities or INSERM. Members of Joint Research Units may be either CNRS researchers or university employees ( ''maîtres de conférences'' or ''professeurs''). Each research unit has a numeric code attached and is typically headed by a university profe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pressure Ionization
Pressure (symbol: ''p'' or ''P'') is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Gauge pressure (also spelled ''gage'' pressure)The preferred spelling varies by country and even by industry. Further, both spellings are often used ''within'' a particular industry or country. Industries in British English-speaking countries typically use the "gauge" spelling. is the pressure relative to the ambient pressure. Various units are used to express pressure. Some of these derive from a unit of force divided by a unit of area; the SI unit of pressure, the pascal (Pa), for example, is one newton per square metre (N/m2); similarly, the pound-force per square inch (psi, symbol lbf/in2) is the traditional unit of pressure in the imperial and US customary systems. Pressure may also be expressed in terms of standard atmospheric pressure; the unit atmosphere (atm) is equal to this pressure, and the torr is defined as of this ...
