In physics, two wave sources are perfectly coherent if they have a constant phase difference and the same frequency. It is an ideal property of waves that enables stationary (i.e. temporally and spatially constant) interference. It contains several distinct concepts, which are limiting cases that never quite occur in reality but allow an understanding of the physics of waves, and has become a very important concept in quantum physics. More generally, coherence describes all properties of the correlation between physical quantities of a single wave, or between several waves or wave packets.
Interference is nothing more than the addition, in the mathematical sense, of wave functions. A single wave can interfere with itself, but this is still an addition of two waves (see Young's slits experiment). Constructive or destructive interferences are limit cases, and two waves always interfere, even if the result of the addition is complicated or not remarkable.
When interfering, two waves can add together to create a wave of greater amplitude than either one (constructive interference) or subtract from each other to create a wave of lesser amplitude than either one (destructive interference), depending on their relative phase. Two waves are said to be coherent if they have a constant relative phase. The amount of coherence can readily be measured by the interference visibility, which looks at the size of the interference fringes relative to the input waves (as the phase offset is varied); a precise mathematical definition of the degree of coherence is given by means of correlation functions.
Coherence, coherency, or coherent may refer to the following,:
Physics
Coherence (physics), an ideal property of waves that enables stationary (i.e. temporally and spatially constant) interference
Coherence (units of measurement), a derived unit that, for a given system of quantities and for a chosen set of base units, is a product of powers of base units with no other proportionality factor than one
Coherence time, the time over which a propagating wave (especially a laser or maser beam) may be considered coherent; the time interval within which its phase is, on average, predictable
In mathematics, and particularly category theory a coherence condition is a collection of conditions requiring that various compositions of elementary morphisms are equal. Typically the elementary morphisms are part of the data of the category.
An illustrative example: a monoidal category
Part of the data of a monoidal category is a chosen morphism
, called the associator:
for each triple of objects in the category. Using compositions of these , one can construct a morphism
Actually, there are many ways to construct such a morphism as a composition of various . One coherence condition that is typically imposed is that these compositions are all equal.
Typically one proves a coherence condition using a coherence theorem, which states that one only needs to check a few equalities of compositions in order to show that the rest also hold. In the above example, one only needs to check that, for all quadruples of objects , the following diagram commutes
Further examples
Two simple examples that illustrate the definition are as follows. Both are directly from the definition of a category.
Subtext is a moderately visual programming language and environment, for writing application software. It is an experimental, research attempt to develop a new programming model, called Example Centric Programming, by treating copied blocks as first class prototypes, for program structure. It uses live text, similar to what occurs in spreadsheets as users update cells, for frequent feedback. It is intended to eventually be developed enough to become a practical language for daily use. It is planned to be open software; the license is not yet determined.
Subtext was created by Jonathan Edwards who submitted a paper on the language to OOPSLA. It was accepted as part of the 2005 conference.
Environment
Early video previews of the Subtext environment were released circa 2006, which demonstrated the semantics of Subtext programs, and the close integration with the Subtex environment and runtime.
Subtext programs are declared and manipulated (or mutated) by adding and linking elements of various types to a syntax tree, and entering in values or names as necessary, as opposed to typing out textual programs. Due to the design of the Subtext language and environment, there is no distinction between a program's representation and its execution. Like spreadsheets, Subtext programs are live executions within an environment and runtime, and programming is direct manipulation of these executions via a graphical environment. Unlike typical functional programming languages, Subtext has simple semantics and is easily applicable to reactive systems that require mutable state, I/O, and concurrency, under a model known as "Reactive Programming".Console input ("invocations") can be utilized via data flow within a Subtext program, allowing users to manipulate values interactively.
Temporal is a compilation album by American post-metal band Isis, containing various demo recordings, unreleased tracks and remixes from throughout the band's history. It was released on November 6, 2012, by Ipecac. The compilation includes demos and alternate versions of songs from Oceanic, Panopticon and Wavering Radiant. It also features songs originally from Sawblade EP and Melvins / Isis. The compilation also includes a DVD of all the band's music videos. This is their second release since their dissolution in 2010.
Temporal are an Australian metal band from Perth. The band formed in late 2010 through brothers Anthony and Stephen Santoro and guitarist Urvin Seeburuth.
After a few lineup changes resulting in the addition of Scott Mcmullen (vocals) and Michael Barr (bass) the band recorded their debut release "Persecution" with Singaporean producer Roland Lim (Make Them Suffer, Birds of Tokyo, Dyscord).
The single was released on 1 March 2012, receiving positive reviews and peaking at #22 on the Triple J Unearthed Charts.
The band recorded their EP Exitium with Roland Lim during September 2012. The album was officially released through Bandcamp on 6 December. The EP peaked at number 5 on the Australian Metal Charts on iTunes
BalletMet is an American ballet company based in Columbus, Ohio. It is also known as BalletMet Columbus.
The current company came into existence in July 1978, with a $200,000 grant from the Battelle Memorial Institute Foundation. At that time it consisted of three staff and 12 dancers, and soon hired Wayne Soulant as its first artistic director. By 1997, the company had expanded to 25 dancers.

🤯തലച്ചോറ് കുഴച്ച് അവിയൽ പരുവം ആക്കുന്ന sci-fi പടം | Coherence Movie Explained in Malayalam
Todo comienza con una cena con amigos durante la noche en que un cometa pasará muy próximo a la Tierra. Sus consecuencias no se saben pero los antecedentes ocurridos a principio de siglo no auguran nada bueno. En aquel entonces, tras el paso del cometa, se dieron casos de personas desorientadas que no podían reconocer ni a su propia familia. La cena comienza y, pese a algunos fallos con los teléfonos móviles, parece que la noche será tranquila. Pero pronto las cosas empezarán a enrarecerse hasta cotas insospechadas. A la incertidumbre y la tensión creadas tras el primer apagón de luz se suman a las pequeñas desavenencias que existen entre ellos.
