Supersonic Low Altitude Missile
The Supersonic Low Altitude Missile, known as SLAM or Vought SLAM, was an American Cold War nuclear ramjet cruise missile project canceled in 1964 before any flight.
Supersonic retropropulsion
Supersonic retropropulsion is an entry, descent, and landing technology that fires retrorockets against supersonic airflow to slow a spacecraft, a candidate for landing large payloads on Mars.
Supersonic speed
Supersonic speed, or supersonic flight, is speed above Mach 1, faster than the local speed of sound, about 761 mph at sea level, producing shock waves and sonic booms.
Supersonic transport
A supersonic transport is a passenger airliner designed to cruise faster than the speed of sound; only Concorde and the Soviet Tu-144 entered commercial service.
Superspace
Superspace is an extension of ordinary spacetime, adding anticommuting Grassmann spinor coordinates so superfields package particles and their superpartners; it was introduced in 1974 by Abdus Salam and John Strathdee.
Superstable theories
In model theory, a superstable theory is a stable theory in which every type does not fork over a finite subset of its domain, a class introduced by Saharon Shelah.
Superstar (1999 film)
Superstar (1999 film) is an American-Canadian comedy directed by Bruce McCulloch. It stars Molly Shannon as Mary Katherine Gallagher, an SNL character who enters a talent contest.
Superstar (Delaney and Bonnie song)
Superstar, originally Groupie (Superstar), is a 1969 ballad by Bonnie Bramlett and Leon Russell, first recorded by Delaney & Bonnie as a B-side with Eric Clapton, made famous by the Carpenters' 1971 No. 2 US hit.
Superstar K
Superstar K (슈퍼스타K) was a South Korean television singing audition series on the cable channel Mnet, broadcast from 2009 to 2016 and credited with starting Korea's nationwide audition-program boom.
Superstar Singer (सुपरस्टार सिंगर)
Superstar Singer (सुपरस्टार सिंगर) is a Hindi-language children's singing reality show on Sony Entertainment Television and SonyLIV, premiering 29 June 2019, with three seasons, captain-mentored teams, a super judge, and viewer-vote eliminations.
Superstate
A superstate is a centralized political entity formed from multiple states with total authority. It is most famously known for George Orwell's totalitarian Oceania in Nineteen Eighty-Four.
Superstition
Superstition is a belief or practice based on ignorance, fear of the unknown, trust in magic or luck, or a false view of cause and effect.
Superstition (song)
Superstition: 1972 funk single by Stevie Wonder, lead track of Talking Book, written with Jeff Beck, a Billboard Hot 100 number one and two-time Grammy winner built on a Hohner Clavinet riff.
Superstition in India
Superstition in India covers supernatural-causality beliefs from auspicious dating (87% of Hindus) to black magic and witch-hunting. Studied via the Indian Superstition Scale (18 items), contested by Atheist miracle-exposure activists, and lacking a comprehensive central anti-superstition law.
Superstition Mountains
The Superstition Mountains are a volcanic range about 60 km east of Phoenix, Arizona, formed of ash-flow tuff erupted roughly 25 to 15 million years ago, home to the 160,115-acre Superstition Wilderness and Weaver's Needle.
Superstore (TV series)
Superstore (NBC, 2015–2021) is an American workplace sitcom created by Justin Spitzer, set at Cloud 9, a fictional big-box store in St. Louis, starring America Ferrera and Ben Feldman, notable for its union-organizing storyline.
Superstrate configuration
The superstrate configuration is a thin-film solar cell architecture in which light enters through the transparent glass support, contrasting with the substrate configuration that allows opaque supports.
Superstring theory
Superstring theory is a quantum theory in which fundamental particles arise as vibrations of one-dimensional strings; consistency requires ten spacetime dimensions, and its spectrum contains the graviton.
Superstruct Entertainment
Superstruct Entertainment is a European live-events company founded in 2017 that owns 80 music festivals across Europe and Australia, including Wacken Open Air and Sziget.
Superstructure (ship)
A superstructure is the decked structure above a ship's main deck, extending side to side and housing the bridge, accommodation, masts, and stacks; aircraft carriers carry theirs as an island.
Supersymmetric localization
Supersymmetric localization is a technique in quantum field theory that uses a fermionic symmetry to reduce path integrals to finite-dimensional integrals, enabling exact computation of partition functions and supersymmetric observables.
Supersymmetric quantum mechanics
Supersymmetric quantum mechanics (SUSY QM) is a class of quantum systems with a fermionic supercharge pairing bosonic and fermionic states, introduced by Edward Witten in 1981 and used in solvable potentials and topology.
Supersymmetric Yang–Mills theory
Supersymmetric Yang–Mills theory is a gauge theory in which Yang–Mills fields are accompanied by superpartners, with the N=4 case conformal and central to holographic duality.
Supersymmetry
Supersymmetry, or SUSY, is a proposed extension of the Standard Model in which every particle has a partner whose spin differs by half a unit, developed in the 1970s.
Supersymmetry algebra
The supersymmetry algebra is the graded Lie algebra extending the Poincaré algebra with fermionic supercharges that turn bosons into fermions; the Haag–Łopuszański–Sohnius theorem of 1975 shows it is the only such extension.
Supersynchronous orbit
A supersynchronous orbit, or supersynchronous transfer orbit, is an Earth orbit above geosynchronous altitude of 35,786 km, used for fuel-saving transfers to GEO and satellite disposal.
Supertaça Cândido de Oliveira
The Supertaça Cândido de Oliveira, also known as the Portuguese Super Cup, is Portugal's annual football super cup between the Primeira Liga and Taça de Portugal winners.
Supertask
A supertask is a task consisting of infinitely many steps completed in a finite amount of time. The term was coined by philosopher J. F. Thomson in 1954.
Supertaster
Supertaster: coined by Linda Bartoshuk in 1991 for people who taste PROP/PTC as intensely bitter; about 25% of Americans, more fungiform papillae, TAS2R38-related but not explained by it alone.
Supertramp
Supertramp: British rock band formed 1969 by Rick Davies and Roger Hodgson, funded by Stanley Miesegaes; breakthrough Crime of the Century (1974), peak Breakfast in America (1979), 18 million copies, two Grammys.
