Equality before the law
Equality before the law: the principle that all persons, including the state, are subject to the same laws; rooted in Magna Carta (1215), guaranteed by UDHR Article 7, and analyzed through formal versus substantive equality.
Equality of outcome
Equality of outcome, also called equality of results, is the political ideal that people end up with the same goods or status, contrasted with equality of opportunity and defended by Anne Phillips (2004).
Equalization (audio)
Equalization (EQ), or audio equalizer, adjusts the balance of frequencies in an audio signal using filters that boost or cut parts of the spectrum, in recording, mixing, and broadcast.
Equalization of the census: Yanzhou edict and the Taizong registers
The equalization of the census (定户等) was the Tang dynasty's system of grading every registered household into nine grades by assets, established in 624 and reassessed every three years.
Equalization payments in Canada
Equalization payments in Canada, also called equalization, are unconditional federal transfers to provinces with below-average revenue-raising capacity, dating from 1957 and paying $25.3 billion to seven provinces in 2024-25.
Equalized corvée and courier service reforms
The equalized corvée and courier service reforms (均徭与驿传改革) were two linked Ming dynasty efforts to rationalize compulsory labor service, shifting it toward payment in silver.
Equalized corvée service (junyao)
Equalized corvée service (junyao, 均徭) was one of three Ming dynasty labor-service categories, created in Jiangxi early in the Zhengtong era, ranking households so burdens were roughly equal.
Equals (film)
Equals (2015) is a dystopian sci-fi romance directed by Drake Doremus, starring Nicholas Hoult and Kristen Stewart as lovers in the emotion-free Collective; premiered at Venice 2015, released by A24 in July 2016.
Equals sign
The equals sign, also called the equality sign, is a mathematical symbol stating that two expressions have the same value, introduced by Robert Recorde in 1557.
Equanimeous St. Brown
Equanimeous St. Brown (born 1996, Placentia, CA) is an NFL wide receiver, Notre Dame alum, drafted 207th overall by Green Bay in 2018; later Bears, Saints, 49ers; older brother of Amon-Ra St. Brown.
Equanimity
Equanimity is a balanced state of mind, also known as emotional stability, that responds evenly to all experiences. It originates in Buddhist thought and is studied in modern psychology.
Équateur Province
Équateur Province (Province de l'Équateur) is a DRC province in the northwest with capital Mbandaka, area 103,902 km², created 1917 and split into five provinces in 2015; forest, river transport, and high poverty define it.
Equating (psychometrics)
Equating (psychometrics) is a method for adjusting scores on test forms that differ in difficulty. This enables scores to be used interchangeably as if from the same test.
Equation
An equation is a mathematical statement that two expressions are equal, written with an equals sign; identities hold for all values, conditional equations for some, and contradictions for none.
Equation Festival (festival)
Equation Festival is an underground electronic music festival held in northern Vietnam since 2017, known for its cave rave in a limestone cavern in Mai Châu.
Equation Group
Equation Group is a highly sophisticated cyber espionage actor named by Kaspersky Lab in February 2015, suspected of links to the NSA's Tailored Access Operations unit.
Equation of motion coupled cluster
Equation-of-motion coupled cluster (EOM-CC) is a family of quantum-chemistry methods that computes excited, ionized, electron-attached, and spin-flip states of molecules from a coupled-cluster ground state.
Equation of state
An equation of state, also called a state equation, relates the pressure, volume, and temperature of a thermodynamic system, as in the ideal gas law PV = nRT.
Equation of state of quark–gluon plasma
The equation of state of quark–gluon plasma relates energy density, pressure, entropy density, and temperature of deconfined QCD matter, computed by lattice QCD and used in heavy-ion collision modeling.
Equation of state parameter w
In cosmology, the equation of state parameter w is the dimensionless ratio of pressure to energy density of a cosmic component, the standard way of characterizing dark energy.
Equation of time
The equation of time is the difference between apparent solar time on a sundial and mean clock time, reaching 16 minutes over the year due to Earth's axial tilt and elliptical orbit.
Equation solving
Equation solving, also called solving an equation, is the task of finding values of unknowns that make equations true, either exactly in symbols or approximately by numerical methods.
Equational logic
Equational logic is the formal logic whose only formulas are identities s = t between terms, underlying universal algebra and term rewriting; Birkhoff proved it sound and complete in 1935.
Equations for a falling body
The equations for a falling body, or law of falling bodies, give the position and velocity of an object falling under gravity with constant acceleration.
Equations of motion
An equation of motion is a differential equation that determines a physical system's state at later times from its initial state, as in F = ma.
Equator
The Equator is the imaginary line at 0 degrees latitude halfway between the poles, dividing Earth into two hemispheres and measuring about 40,075 km around.
Equatorial coordinate system
The equatorial coordinate system is the astronomical system that specifies positions on the celestial sphere by right ascension and declination, used in star charts, telescope pointing, and most astronomical catalogs.
Equatorial Energia
Equatorial Energia S.A. is a Brazilian multi-utilities holding company founded in 1999, the third largest electricity distribution group in Brazil, with seven distributors serving about 14 million consumers.
Equatorial Guinea
Equatorial Guinea (Guinea Ecuatorial), central African country of Río Muni and islands including Bioko; only Spanish-speaking African country, ruled by Obiang since 1979, oil-dependent economy in prolonged decline since 2015.
