Equation
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign . The word ''equation'' and its cognates in other languages may have subtly different meanings; for example, in French an ''équation'' is defined as containing one or more variables, while in English, any well-formed formula consisting of two expressions related with an equals sign is an equation. ''Solving'' an equation containing variables consists of determining which values of the variables make the equality true. The variables for which the equation has to be solved are also called unknowns, and the values of the unknowns that satisfy the equality are called solutions of the equation. There are two kinds of equations: identities and conditional equations. An identity is true for all values of the variables. A conditional equation is only true for particular values of the variables. An equation is written as two expressions, connected by a ...

Chemical Equation
A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas. The reactant entities are given on the left-hand side and the product entities on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the products to show the direction of the reaction. The chemical formulas may be symbolic, structural (pictorial diagrams), or intermixed. The coefficients next to the symbols and formulas of entities are the absolute values of the stoichiometric numbers. The first chemical equation was diagrammed by Jean Beguin in 1615. Structure A chemical equation (see an example below) consists of a list of reactants (the starting substances) on the left-hand side, an arrow symbol, and a list of products (substances formed in the chemical reaction) on the right-hand side. Each substance is specified by its chemical formula, optionally preceded by a number called ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Equation Clock
An equation clock is a mechanical clock which includes a mechanism that simulates the equation of time, so that the user can read or calculate solar time, as would be shown by a sundial. The first accurate clocks, controlled by pendulums, were patented by Christiaan Huyghens in 1657. For the next few decades, people were still accustomed to using sundials, and wanted to be able to use clocks to find solar time. Equation clocks were invented to fill this need. Early equation clocks have a pointer that moves to show the equation of time on a dial or scale. The clock itself runs at constant speed. The user calculates solar time by adding the equation of time to the clock reading. Later equation clocks, made in the 18th Century, perform the compensation automatically, so the clock directly shows solar time. Some of them also show Local mean time, mean time, which is often called "clock time". Simulation mechanisms All equation clocks include a mechanism that simulates the equation ...

Equation Of State
In physics, chemistry, and thermodynamics, an equation of state is a thermodynamic equation relating state variables, which describe the state of matter under a given set of physical conditions, such as pressure, volume, temperature, or internal energy. Most modern equations of state are formulated in the Helmholtz free energy. Equations of state are useful in describing the properties of pure substances and mixtures in liquids, gases, and solid states as well as the state of matter in the interior of stars. Overview At present, there is no single equation of state that accurately predicts the properties of all substances under all conditions. An example of an equation of state correlates densities of gases and liquids to temperatures and pressures, known as the ideal gas law, which is roughly accurate for weakly polar gases at low pressures and moderate temperatures. This equation becomes increasingly inaccurate at higher pressures and lower temperatures, and fails to predict ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Equation (band)
Equation were a British, young Devon-based folk supergroup formed in 1995, which combined the core talents of the Lakeman Brothers with Kathryn Roberts and Kate Rusby, later replaced for a spell by Cara Dillon. Their first single "He Loves Me" was originally released in 1996 on the Blanco y Negro- WEA label and was followed by four studio albums. ''The Times'' reviewed their first album release ''Hazy Daze''. in 1998, scoring 7/10 and giving a favourable comparison to Fairport Convention Fairport Convention are an English folk rock band, formed in 1967 by guitarists Richard Thompson and Simon Nicol, bassist Ashley Hutchings and drummer Shaun Frater (with Frater replaced by Martin Lamble after their first gig.)

Equation Group
The Equation Group, classified as an advanced persistent threat, is a highly sophisticated threat actor suspected of being tied to the Tailored Access Operations (TAO) unit of the United States National Security Agency (NSA). Kaspersky Labs describes them as one of the most sophisticated cyber attack groups in the world and "the most advanced ... we have seen", operating alongside the creators of Stuxnet and Flame. Most of their targets have been in Iran, Russia, Pakistan, Afghanistan, India, Syria, and Mali. The name originated from the group's extensive use of encryption. By 2015, Kaspersky documented 500 malware infections by the group in at least 42 countries, while acknowledging that the actual number could be in the tens of thousands due to its self-terminating protocol. In 2017, WikiLeaks published a discussion held within the CIA on how it had been possible to identify the group. One commenter wrote that "the Equation Group as labeled in the report does not relate to a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Equation
"The Equation" is the eighth episode of the first season of the American science fiction drama television series ''Fringe''. The episode follows the Fringe team's investigation into the kidnapping of a young musical prodigy ( Charlie Tahan) who has become obsessed with finishing one piece of music. Dr. Walter Bishop (John Noble) returns to St. Claire's Hospital in an effort to find the boy's whereabouts. The episode was written by supervising producer J. R. Orci and co-executive producer David H. Goodman, and was directed by Gwyneth Horder-Payton. Actress Gillian Jacobs guest starred as the boy's kidnapper. The episode featured her character in a "pretty violent and quite messy" fight with Olivia Dunham (Anna Torv), Torv's first for the series. The two actresses spent several weeks practicing the fight's choreography. "The Equation" first aired in the United States on November 18, 2008, garnering an estimated 9.175 million viewers. The episode was the Fox network's fifth rank ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windowlicker
"Windowlicker" is a song by British electronic musician Aphex Twin, released on 22 March 1999 as a single by Warp Records. The artwork for the single was created by Chris Cunningham, with additional work by The Designers Republic. Cunningham also directed the song's music video, which was nominated for the Brit Award for Best British Video. The song peaked at number 16 on the UK Singles Chart, and was later voted by fans as Warp Records' most popular song for its 2009 '' Warp20'' compilation. ''Pitchfork'' included the song at number 12 on their list ''Top 200 Tracks of the 90s''. Music Characteristics "Windowlicker" has been described variously as "uncompromising cyborg R&B", " hip-hop written in the language of glitches", and "eerie lounge-porn music"; the track's "sleazy, erotic ambiance connote images and emotions alien to James' previous compositions." Heavily digitally processed and rhythmically rearranged breakbeats prominently appear in the song's backing track. Gasp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
