Gwalior
Gwalior() is a major city in the central Indian state of Madhya Pradesh; it lies in northern part of Madhya Pradesh and is one of the Counter-magnet cities. Located south of Delhi, the capital city of India, from Agra and from Bhopal, the state capital, Gwalior occupies a strategic location in the Gird region of India. The historic city and its fortress have been ruled by several historic Indian kingdoms. From the Kachchhapaghatas in the 10th century, Tomars in the 13th century, it was passed on to the Mughal Empire, then to the Maratha in 1754, and the Scindia dynasty of Maratha Empire in the 18th century. In April 2021, It was found that Gwalior had the best air quality index (AQI 152) amongst the 4 major cities in Madhya Pradesh. Besides being the administrative headquarters of Gwalior district and Gwalior division, Gwalior has many administrative offices of the Chambal division of northern Madhya Pradesh. Several administrative and judicial organisations, commission ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General Relativity
General relativity, also known as the general theory of relativity and Einstein's theory of gravity, is the geometric theory of gravitation published by Albert Einstein in 1915 and is the current description of gravitation in modern physics. General relativity generalizes special relativity and refines Newton's law of universal gravitation, providing a unified description of gravity as a geometric property of space and time or four-dimensional spacetime. In particular, the ' is directly related to the energy and momentum of whatever matter and radiation are present. The relation is specified by the Einstein field equations, a system of second order partial differential equations. Newton's law of universal gravitation, which describes classical gravity, can be seen as a prediction of general relativity for the almost flat spacetime geometry around stationary mass distributions. Some predictions of general relativity, however, are beyond Newton's law of universal gravitat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

INSPIRE-HEP
INSPIRE-HEP is an open access digital library for the field of high energy physics (HEP). It is the successor of the Stanford Physics Information Retrieval System (SPIRES) database, the main literature database for high energy physics since the 1970s. History SPIRES was (in addition to the CERN Document Server (CDS), arXiv and parts of Astrophysics Data System) one of the main Particle Information Resources. A survey conducted in 2007 found that SPIRES database users wanted the portal to provide more services than the, at that time, already 30-year-old system could provide. On the second annual Summit of Information Specialists in Particle Physics and Astrophysics in May 2008, the physics laboratories CERN, DESY, SLAC and Fermilab therefore announced that they would work together to create a new Scientific Information System for high energy physics called INSPIRE. It interacts with other HEP service providers like arXiv.org, Particle Data Group, NASA's Astrophysics Data System. and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

American Physical Society
The American Physical Society (APS) is a not-for-profit membership organization of professionals in physics and related disciplines, comprising nearly fifty divisions, sections, and other units. Its mission is the advancement and diffusion of knowledge of physics. The society publishes more than a dozen scientific journals, including the prestigious '' Physical Review'' and ''Physical Review Letters'', and organizes more than twenty science meetings each year. APS is a member society of the American Institute of Physics. Since January 2021 the organization has been led by chief executive officer Jonathan Bagger. History The American Physical Society was founded on May 20, 1899, when thirty-six physicists gathered at Columbia University for that purpose. They proclaimed the mission of the new Society to be "to advance and diffuse the knowledge of physics", and in one way or another the APS has been at that task ever since. In the early years, virtually the sole activity of the AP ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BRST Quantization
In theoretical physics, the BRST formalism, or BRST quantization (where the ''BRST'' refers to the last names of Carlo Becchi, , Raymond Stora and Igor Tyutin) denotes a relatively rigorous mathematical approach to Quantization (physics), quantizing a quantum field theory, field theory with a gauge symmetry. Quantization (physics), Quantization rules in earlier quantum field theory (QFT) frameworks resembled "prescriptions" or "heuristics" more than proofs, especially in non-abelian group, non-abelian QFT, where the use of "ghost fields" with superficially bizarre properties is almost unavoidable for technical reasons related to renormalization and anomaly cancellation. The BRST global supersymmetry introduced in the mid-1970s was quickly understood to rationalize the introduction of these Faddeev–Popov ghosts and their exclusion from "physical" asymptotic states when performing QFT calculations. Crucially, this symmetry of the path integral is preserved in loop order, and thu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Oldenburg
The Carl von Ossietzky University of Oldenburg (german: Carl von Ossietzky Universität Oldenburg) is a university located in Oldenburg, Germany. It is one of the most important and highly regarded educational facilities in northwestern Germany and specialises in interdisciplinary and sustainable development studies and renewable energy studies with focus on solar and wind energy. History The first teachers training was held in Oldenburg as early as 1793, launched by Duke Peter Friedrich Ludwig. A garden seminar for teachers training was created in 1882. During the Weimar Republic, the establishment of the ''Pedagogical Academy'' (Pädagogische Akademie) in Oldenburg in 1929 enabled the vocational training of teachers. On 1 October 1945, the institution reopened in postwar Germany. In 1948 it was renamed the ''Pedagogical College Oldenburg'' (Pädagogische Hochschule Oldenburg). The first step towards the university was taken on 23 February 1959 with the decision of the ci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
