French-Armenian
Armenians in France ( hy, ֆրանսահայեր, translit=Fransahayer; french: Arméniens de France) are France, French citizens of Armenians, Armenian ancestry. The French Armenian community is, by far, the largest in the European Union and the Armenian diaspora#Population by country, third largest in the world, after Armenians in Russia, Russia and the Armenian Americans, United States. Although the first Armenians settled in France in the Middle Ages, like most of the Armenian diaspora, the Armenian community in France was established by survivors of the Armenian genocide of 1915. Others came through the second half of the 20th century, fleeing political and economic instability in the Middle Eastern countries (Turkey, Lebanon, Syria, Egypt and Iran) and, more recently, from Armenia. History Early history Armenians have a long history of settlement in France. The first Armenians appeared in Francia in the Early Middle Ages. In 591an Armenian bishopnamed Simon is recorded to h ...

Quantum Field Theory
In theoretical physics, quantum field theory (QFT) is a theoretical framework that combines classical field theory, special relativity, and quantum mechanics. QFT is used in particle physics to construct physical models of subatomic particles and in condensed matter physics to construct models of quasiparticles. QFT treats particles as excited states (also called Quantum, quanta) of their underlying quantum field (physics), fields, which are more fundamental than the particles. The equation of motion of the particle is determined by minimization of the Lagrangian, a functional of fields associated with the particle. Interactions between particles are described by interaction terms in the Lagrangian (field theory), Lagrangian involving their corresponding quantum fields. Each interaction can be visually represented by Feynman diagrams according to perturbation theory (quantum mechanics), perturbation theory in quantum mechanics. History Quantum field theory emerged from the wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quantum Thermodynamics
Quantum thermodynamics is the study of the relations between two independent physical theories: thermodynamics and quantum mechanics. The two independent theories address the physical phenomena of light and matter. In 1905, Albert Einstein argued that the requirement of consistency between thermodynamics and electromagnetism leads to the conclusion that light is quantized obtaining the relation E= h \nu . This paper is the dawn of quantum theory. In a few decades quantum theory became established with an independent set of rules. Currently quantum thermodynamics addresses the emergence of thermodynamic laws from quantum mechanics. It differs from quantum statistical mechanics in the emphasis on dynamical processes out of equilibrium. In addition, there is a quest for the theory to be relevant for a single individual quantum system. Dynamical view There is an intimate connection of quantum thermodynamics with the theory of open quantum systems. Quantum mechanics inserts dynamic ...

Theory Of Measurement
Measurement is the quantification of attributes of an object or event, which can be used to compare with other objects or events. In other words, measurement is a process of determining how large or small a physical quantity is as compared to a basic reference quantity of the same kind. The scope and application of measurement are dependent on the context and discipline. In natural sciences and engineering, measurements do not apply to nominal properties of objects or events, which is consistent with the guidelines of the ''International vocabulary of metrology'' published by the International Bureau of Weights and Measures. However, in other fields such as statistics as well as the social and behavioural sciences, measurements can have multiple levels, which would include nominal, ordinal, interval and ratio scales. Measurement is a cornerstone of trade, science, technology and quantitative research in many disciplines. Historically, many measurement systems existed for t ...

Académie Des Sciences
The French Academy of Sciences (French: ''Académie des sciences'') is a learned society, founded in 1666 by Louis XIV at the suggestion of Jean-Baptiste Colbert, to encourage and protect the spirit of French scientific research. It was at the forefront of scientific developments in Europe in the 17th and 18th centuries, and is one of the earliest Academies of Sciences. Currently headed by Patrick Flandrin (President of the Academy), it is one of the five Academies of the Institut de France. History The Academy of Sciences traces its origin to Colbert's plan to create a general academy. He chose a small group of scholars who met on 22 December 1666 in the King's library, near the present-day Bibliothèque Nationals, and thereafter held twice-weekly working meetings there in the two rooms assigned to the group. The first 30 years of the Academy's existence were relatively informal, since no statutes had as yet been laid down for the institution. In contrast to its British ...

Dirk Ter Haar
Dirk ter Haar FRSE FIP DSc (; Oosterwolde, 19 April 1919 – Drachten, 3 September 2002) was an Anglo-Dutch physicist. Life Dirk ter Haar was born at Oosterwolde in the province Friesland in the north of the Netherlands on 19 April 1919. He studied physics at the University of St Andrews in Scotland and Oxford University in England, obtaining an MA degree before carrying out postgraduate studies at Leiden University. In 1946 he was a research fellow of Niels Bohr at the Institute for Theoretical Physics in Copenhagen (now the Niels Bohr Institute), and received his PhD in Leiden in 1948 from Hendrik Kramers for a dissertation on the origin of the Solar System. From 1947 to 1950 he was a visiting associate professor of physics at Purdue University. In 1950 he obtained a post as professor of physics at the University of St. Andrews, and later became a British citizen. In 1952 he was elected a Fellow of the Royal Society of Edinburgh. His proposers were Jack Allen, David Jack, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Corps Des Mines
The ''Corps des mines'' is the foremost technical Grand Corps of the French State (grands corps de l'Etat). It is composed of the state industrial engineers. The Corps is attached to the French Ministry of Economy and Finance. Its purpose is to entice French students in mathematics and physics to serve the government and train them for executive careers in France. Members are educated at the École nationale supérieure des mines de Paris, also known as Mines ParisTech. Each year, the Corps recruits between 10 and 20 members. Most of them are alumni from École polytechnique, who are usually among the top ranked students, others come from École normale supérieure (ENS), Télécom Paris or regular graduates of the Mines ParisTech. Upon graduation, ''Corps des mines'' engineers hold executive positions in the French administration. ''Corps des mines'' engineers tend to hold top executive positions in France's major industrial companies in the course of their career. Being admitt ...
