Madhubani District
Madhubani district is one of the thirty-eight districts of Bihar, India, and is a part of Darbhanga division. Its administrative headquarters are located in Madhubani. The district has an area of and has a population of 4,487,379 (as of 2011). Madhubani is the largest fish-producing district of Bihar in 2022. History Madhubani became a district in 1972 when it was split from Darbhanga district. It is believed that Baliraajgadh, an archaeological site which lies in modern-day Madhubani district was the capital of the ancient Mithila Kingdom. In 2019 a Meteorite fell at a farm in village which was named scholars as Mahadeva Meteorite of the Madhubani district in India. Culture Madhubani art or Mithila painting was traditionally created by the women of various communities in Mithila region of India and Nepal. It originated from Madhubani district of Mithila region of Bihar, and, it is popularly called Mithila painting or Madhubani art. Madhubani is also a major expor ...

STAR Experiment
The STAR detector (for Solenoidal Tracker at RHIC) is one of the four experiments at the Relativistic Heavy Ion Collider (RHIC) in Brookhaven National Laboratory, United States. The primary scientific objective of STAR is to study the formation and characteristics of the quark–gluon plasma (QGP), a state of matter believed to exist at sufficiently high energy densities. Detecting and understanding the QGP allows physicists to understand better the Universe in the seconds after the Big Bang, when the presently-observed symmetries (and asymmetries) of the Universe were established. Unlike other physics experiments where a theoretical prediction can be tested directly by a single measurement, STAR must make use of a variety of simultaneous studies in order to draw strong conclusions about the QGP. This is due both to the complexity of the system formed in the high-energy nuclear collision and the unexplored landscape of the physics studied. STAR therefore consists of several types o ...

Pramana (journal)
''Pramana'' – ''Journal of Physics'', was launched in July 1973. ''Pramana'' (which in Sanskrit means "source of valid knowledge, a standard") is the outcome of a nationwide effort by Indian physicists to disseminate their best efforts in physics. The journal is published by the Indian Academy of Sciences in collaboration with the Indian National Science Academy and the Indian Physics Association. The journal presents refereed papers covering current research in physics, both original contributions---research papers, brief reports or rapid communications---and invited reviews. ''Pramana'' also publishes special issues devoted to advances in specific areas of Physics. ''Pramana – Journal of Physics'' is now distributed in print outside India and online worldwide by Springer, co-publisher of the journal together with the Indian Academy of Sciences. On Springer, ''Pramana – Journal of Physics'is part of SpringerLink, one of the world's leading interactive databases of high qu ...

Physicist
A physicist is a scientist who specializes in the field of physics, which encompasses the interactions of matter and energy at all length and time scales in the physical universe. Physicists generally are interested in the root or ultimate causes of Phenomenon, phenomena, and usually frame their understanding in mathematical terms. They work across a wide range of Physics#Research fields, research fields, spanning all length scales: from atom, sub-atomic and particle physics, through biological physics, to physical cosmology, cosmological length scales encompassing the universe as a whole. The field generally includes two types of physicists: Experimental physics, experimental physicists who specialize in the observation of natural phenomena and the development and analysis of experiments, and Theoretical physics, theoretical physicists who specialize in mathematical modeling of physical systems to rationalize, explain and predict natural phenomena. Physicists can apply their k ...

Photon Multiplicity Detector (PMD)
Photon Multiplicity Detector (PMD) is a detector used in the measurement of the multiplicity and spatial distribution of photons produced in nucleus - nucleus collisions. In short form, it is denoted by PMD. It was incorporated in the WA93 experiment. The funding for research and development of the design of PMD was done by the Department of Atomic Energy (DAE) and the Department of Science and Technology (DST) of the Government of India. The detector was constructed in the collaboration of Variable Energy Cyclotron Centre in Kolkata, Institute of Physics in Bhubaneswar and group of universities at Chandigarh, Jaipur and Jammu. Description A PMD typically consists of two main layers Veto Detector and Preshower Detector. Veto Detector layer is designed to reject charged particles. Photons pass through a converter in Preshower Detector layer, initiating an electromagnetic shower. The detector then measures the number of cells activated by the shower, providing information about t ...

Quark–gluon Plasma
Quark–gluon plasma (QGP or quark soup) is an interacting localized assembly of quarks and gluons at Thermodynamic equilibrium#Local and global equilibrium, thermal (local kinetic) and (close to) chemical (abundance) equilibrium. The word ''plasma'' signals that free color charges are allowed. In a 1987 summary, Léon Van Hove pointed out the equivalence of the three terms: quark gluon plasma, quark matter and a new state of matter. Since the temperature is above the Hagedorn temperature—and thus above the scale of light u,d-quark mass—the pressure exhibits the relativistic Stefan–Boltzmann law, Stefan–Boltzmann format governed by temperature to the fourth power ( T^) and many practically massless quark and gluon constituents. It can be said that QGP emerges to be the new phase of strongly interacting matter which manifests its physical properties in terms of nearly free dynamics of practically massless gluons and quarks. Both quarks and gluons must be present in conditions ...
