5290 Langevin
5 (five) is a number, numeral and digit. It is the natural number, and cardinal number, following 4 and preceding 6, and is a prime number. It has attained significance throughout history in part because typical humans have five digits on each hand. In mathematics 5 is the third smallest prime number, and the second super-prime. It is the first safe prime, the first good prime, the first balanced prime, and the first of three known Wilson primes. Five is the second Fermat prime and the third Mersenne prime exponent, as well as the third Catalan number, and the third Sophie Germain prime. Notably, 5 is equal to the sum of the ''only'' consecutive primes, 2 + 3, and is the only number that is part of more than one pair of twin primes, ( 3, 5) and (5, 7). It is also a sexy prime with the fifth prime number and first prime repunit, 11. Five is the third factorial prime, an alternating factorial, and an Eisenstein prime with no imaginary part and real part of the form 3p ...

Langevin (crater)
Langevin is a crater on the far side of the Moon. It is located to the east of the walled plain Campbell, and to the west of the crater Chandler Chandler or The Chandler may refer to: * Chandler (occupation), originally head of the medieval household office responsible for candles, now a person who makes or sells candles * Ship chandler, a dealer in supplies or equipment for ships Arts .... This is a heavily damaged crater that has been worn and battered by multiple overlapping impacts. Apart from the depression Langevin creates in the surface, it is scarcely distinguishable from the surrounding terrain. The outer rim and interior features have lost much of their original definition due to this wear. Multiple small craters lie along the rim, including a cluster along the southwest and a crater along the northeast rim. The interior is pock-marked by many small craterlets. Satellite craters By convention these features are identified on lunar maps by placing the letter on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Institut Laue–Langevin
The Institut Laue–Langevin (ILL) is an internationally financed scientific facility, situated on the Polygone Scientifique in Grenoble, France. It is one of the world centres for research using neutrons. Founded in 1967 and honouring the physicists Max von Laue and Paul Langevin, the ILL provides one of the most intense neutron sources in the world and the most intense continuous neutron flux in the world in the moderator region: 1.5×1015 neutrons per second per cm2, with a thermal power of typically 58.3 MW. The ILL neutron scattering facilities allow the analysis of the structure of conducting and magnetic materials for future electronic devices, the measurement of stresses in mechanical materials. It also allows investigations into macromolecular assemblies, particularly protein dynamics and biomolecular structure. It is a world-renowned centre for Nanoscopic scale, nanoscale science. History The institute was founded by France and Germany, with the United King ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Office Of The Prime Minister And Privy Council
The Office of the Prime Minister and Privy Council (french: Bureau du Premier ministre et du Conseil privé) building, formerly known as the Langevin Block (french: Édifice Langevin, ), is an office building facing Parliament Hill in Ottawa, Ontario, Canada. As the home of the Privy Council Office and Office of the Prime Minister, it is the working headquarters of the executive branch of the Canadian government. The term Langevin Block was previously used as a metonym for the Prime Minister's Office and the Privy Council Office. The building was named after Father of Confederation and cabinet minister Hector-Louis Langevin. Following objections by Indigenous people of the use of Hector Langevin's name, due to allegations regarding Langevin's role in establishing the residential school system associated with the abuse of Indigenous children and attempts to forcibly assimilate them, Prime Minister Justin Trudeau announced the renaming of the building on June 21, 2017. The bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Brillouin And Langevin Functions
The Brillouin and Langevin functions are a pair of special functions that appear when studying an idealized paramagnetic material in statistical mechanics. Brillouin function The Brillouin functionC. Kittel, ''Introduction to Solid State Physics'' (8th ed.), pages 303-4 is a special function defined by the following equation: :B_J(x) = \frac \coth \left ( \frac x \right ) - \frac \coth \left ( \frac x \right ) The function is usually applied (see below) in the context where x'' is a real variable and J is a positive integer or half-integer. In this case, the function varies from -1 to 1, approaching +1 as x \to +\infty and -1 as x \to -\infty. The function is best known for arising in the calculation of the magnetization of an ideal paramagnet. In particular, it describes the dependency of the magnetization M on the applied magnetic field B and the total angular momentum quantum number J of the microscopic magnetic moments of the material. The magnetization is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Langevin Dynamics
In physics, Langevin dynamics is an approach to the mathematical modeling of the dynamics of molecular systems. It was originally developed by French physicist Paul Langevin. The approach is characterized by the use of simplified models while accounting for omitted degrees of freedom by the use of stochastic differential equations. Langevin dynamics simulations are a kind of Monte Carlo simulation. Overview A real world molecular system is unlikely to be present in vacuum. Jostling of solvent or air molecules causes friction, and the occasional high velocity collision will perturb the system. Langevin dynamics attempts to extend molecular dynamics to allow for these effects. Also, Langevin dynamics allows temperature to be controlled like with a thermostat, thus approximating the canonical ensemble. Langevin dynamics mimics the viscous aspect of a solvent. It does not fully model an implicit solvent; specifically, the model does not account for the electrostatic screening and al ...
