quark

1964, applied by U.S. physicist Murray Gell-Mann (b.1929), who said in correspondence with the editors of the OED in 1978 that he took it from a word in James Joyce's "Finnegans Wake" (1939), but also that the sound of the word was in his head before he encountered the printed form in Joyce. German Quark "curds, rubbish" has been proposed as the ultimate inspiration [Barnhart; Gell-Mann's parents were immigrants from Austria-Hungary]. George Zweig, Gell-Mann's co-proposer of the theory, is said to have preferred the name ace for them.

Wikipedia
Quark (company)

Quark Software Inc. (founded 1981 in Denver, Colorado) is a privately owned software company which specializes in omni-channel enterprise publishing software for automating the production of high-value customer communications. The company's original goal was to "create software that would be the platform for publishing", just as quarks are the basis for all matter. The company is best known for its desktop page layout and design software, QuarkXPress, although this has now become secondary to its enterprise software solutions.

Quark (Star Trek)

Quark is a fictional character in the American television series Star Trek: Deep Space Nine. The character, which was played by Armin Shimerman, was depicted as a member of an extraterrestrial race known as the Ferengi, who are stereotypically capitalist and motivated only by profit.

Quark, who often served as the show's comedy relief, may have been named after the 1978 Quark (TV series), which frequently examined science fiction themes from a humorous or satirical perspective.

Quark (disambiguation)

A quark is an elementary particle.

Quark may also refer to:

  • Quark (dairy product), a type of fresh dairy product
  • "Quark", a nonce word in James Joyce's Finnegans Wake, and the origin of the particle name
Quark (kernel)

In computing, Quark is an operating system kernel used in MorphOS. It is a microkernel designed to run totally virtualized computers, called "boxes" (see sandbox). Currently only one "Box" is available, the ABox, that lets users run existing AmigaOS software compiled for MC680x0 and PowerPC processors.

Quark (song)

"Quark" (meaning "rubbish", literally curd) is a punk song by Die Ärzte. It's the fourteenth track and the fourth single from their 1993 album Die Bestie in Menschengestalt. It's about a man, who can't handle the chattering of his consort. The single version criticises the gibberish of politicians. The single version is also on " Das Beste von kurz nach früher bis jetze".

Quark

A quark ( or ) is an elementary particle and a fundamental constituent of matter. Quarks combine to form composite particles called hadrons, the most stable of which are protons and neutrons, the components of atomic nuclei. Due to a phenomenon known as color confinement, quarks are never directly observed or found in isolation; they can be found only within hadrons, such as baryons (of which protons and neutrons are examples), and mesons. For this reason, much of what is known about quarks has been drawn from observations of the hadrons themselves.

Quarks have various intrinsic properties, including electric charge, mass, color charge and spin. Quarks are the only elementary particles in the Standard Model of particle physics to experience all four fundamental interactions, also known as fundamental forces ( electromagnetism, gravitation, strong interaction, and weak interaction), as well as the only known particles whose electric charges are not integer multiples of the elementary charge.

There are six types of quarks, known as flavors: up, down, strange, charm, top, and bottom. Up and down quarks have the lowest masses of all quarks. The heavier quarks rapidly change into up and down quarks through a process of particle decay: the transformation from a higher mass state to a lower mass state. Because of this, up and down quarks are generally stable and the most common in the universe, whereas strange, charm, bottom, and top quarks can only be produced in high energy collisions (such as those involving cosmic rays and in particle accelerators). For every quark flavor there is a corresponding type of antiparticle, known as an antiquark, that differs from the quark only in that some of its properties have equal magnitude but opposite sign.

The quark model was independently proposed by physicists Murray Gell-Mann and George Zweig in 1964. Quarks were introduced as parts of an ordering scheme for hadrons, and there was little evidence for their physical existence until deep inelastic scattering experiments at the Stanford Linear Accelerator Center in 1968. Accelerator experiments have provided evidence for all six flavors. The top quark was the last to be discovered at Fermilab in 1995.

Quark (TV series)

Quark is an American science fiction sitcom starring Richard Benjamin broadcast on NBC. The pilot first aired on May 7, 1977, and the series followed as a mid-season replacement in February 1978. The series was cancelled in April 1978. Quark was created by Buck Henry, co-creator of the spy spoof Get Smart.

The show was set on a United Galaxy Sanitation Patrol Cruiser, an interstellar garbage scow operating out of United Galaxies Space Station Perma One in the year 2226. Adam Quark, the main character, works to clean up trash in space by collecting "space baggies" with his trusted and highly unusual crew.

In its short run, Quark satirized such science fiction as Star Wars, 2001: A Space Odyssey and Flash Gordon. Three of the episodes were direct parodies of Star Trek episodes.

The series won one Emmy Award nomination, for costume designer Grady Hunt's work in the episode "All the Emperor's Quasi-Norms, Part 2".

The complete series was released on DVD on October 14, 2008.

Quark (dairy product)

Quark is a type of fresh dairy product, common in the cuisines of German-speaking countries ( Germany, Austria, Switzerland), northern Europe ( Denmark, Estonia, Finland, Latvia, Lithuania, Norway, Sweden), the Netherlands, Hungary, Albania, Kosovo, Israel, of Slavic peoples (e.g. Czechs, Slovaks, Poles, Russians, Ukrainians and Belarusians), and of Ashkenazi Jews. It is made by warming soured milk until the desired degree of curdling is met, and then strained. It can be classified as fresh acid-set cheese, though in some countries it is traditionally considered a distinct fermented milk product. Traditional quark is made without rennet, but in some modern dairies rennet is added. It is soft, white and unaged, and usually has no salt added.

Dictionaries usually translate it as curd cheese, cottage cheese or sometimes farmer cheese. In Germany, quark and cottage cheese are considered to be different types of fresh cheese, while in Eastern Europe cottage cheese is usually viewed as a type of quark (e.g. Russian for cottage cheese is "зернёный творог" zernyony tvorog, literally "grainy quark").

Quark is similar to French fromage blanc, Indian chhena, and the queso fresco made in the Iberian Peninsula and in some Latin American countries. It is distinct from Italian ricotta because ricotta ( Italian "recooked") is made from scalded whey. Quark is somewhat similar to yogurt cheeses such as the South Asian chak(k)a, the Arabic labneh, and the Central Asian suzma or kashk, but while these products are obtained by straining yogurt (milk fermented with thermophile bacteria), quark is made from soured milk fermented with mesophile bacteria.
