Definitions

from The American Heritage® Dictionary of the English Language, 5th Edition.

  • noun A soft, creamy, usually unsalted cheese traditional to central Europe and made from cow's milk that is coagulated by the lactic acid produced by bacteria rather than by the use of rennet.
  • noun Any of a class of six fundamental fermions, two in each of the three generations, one having an electric charge of − 1/3 , the other, + 2/3 , comprising the down, up, strange, charm, bottom, and top quarks. Quarks are the basic components of all hadrons.
  • noun Any of the six quarks' associated antiparticles, the antiquarks.

from The Century Dictionary.

  • noun Same as quawk.

  • noun a soft creamy cheese. The Russian quark and Finnish quark are somewhat different. The Russian version is firmer in consistency and contains about 15% milk fat, whereas the Finnish quark often contains less than 1% milk fat.
  • noun physics In the Standard Model, an elementary subatomic particle which forms matter. Quarks are never found alone in nature and combine to form hadrons, such as protons and neutrons.

  • noun fresh unripened cheese of a smooth texture made from pasteurized milk, a starter, and rennet
  • noun (physics) hypothetical truly fundamental particle in mesons and baryons; there are supposed to be six flavors of quarks (and their antiquarks), which come in pairs; each has an electric charge of +2/3 or -1/3

German Quark, from Middle High German quarc

from Wiktionary, Creative Commons Attribution/Share-Alike License

First used in 1963 by the discoverer of quarks, Murray Gell-Mann, to name these new particles. The literary connection to James Joyce's Finnegans Wake was asserted later (quote below).

Examples

  • Seeing the word "quark" in James Joyce's "Finnegan's Wake" induced him to make the spelling change.

    Week in Words

  • The “beauty” quark is particularly good for probing this question because b-quarks and anti-b-quarks behave “more differently” than other particles and their antimatter counterparts.

    B is for Beauty

  • The “beauty” quark is particularly good for probing this question because b-quarks and anti-b-quarks behave “more differently” than other particles and their antimatter counterparts.

  • The heaviest known elementary particle, the top quark is one of the fundamental building blocks of nature and understood to be an ingredient of the nuclear soup just after the Big Bang.

    Science

  • When the neutrino beam method was invented by the Columbia team at the beginning of the 1960s the quark concept was still unknown, and the method has only later become important in quark research.

  • But to understand the structure of the new psi particle a fourth quark is very likely necessary, in the opinion of many researchers.

  • The result is what researchers call a quark-gluon plasma QGP, which hasn't been present in significant quantities since shortly after the origin of the Universe.

    Ars Technica

  • In both cases, the top quark is short-lived and decays, for example, into a bottom quark, a lepton (such as a muon) and a neutrino.

  • Actually, the word quark is in the OED as a verb meaning ` croak, 'with 19th-century references to frogs, rooks, and herons.

  • I'm fascinated by true hypotheses. I sprinkle them in the garden between the gnomes.

  • But it's not a true hypothesis--it's a hypothetical, truly fundamental particle... or am I misunderstanding?

    Ah, who cares. It's still WeirdNet.

  • I think quarks have a certain je ne sais quoi, how you say it, charm.

    Unless you are in Germany where quark is just another name for a faintly gritty yogurt-like substance.

  • I believe the word comes from Finnegan's Wake by James Joyce.

  • SoG. Yes it does, courtesy of Murray Gell-Mann. Though, for reasons which are obscure (to me, at any rate), the name of Joyce's magnum opus/convoluted practical joke on scholars is written without an apostrophe.

    December 2, 2007

  • I didn't know that Joyce invented quarks. Hail Wordie!

    December 2, 2007

  • @sionnach: I apologise for my ignorant apostrophe: consider it removed.

    December 2, 2007

  • I'm down with what you're saying Sionnach, that quarks have a certain charm, although that sounds pretty strange. You're usually on top of such things, and cut straight to what's up and getting to the bottom of such things. Hopefully bashing WordNet is just a flavor of the week, since it isn't actually a dictionary.

  • A Secret Squirrel cartoon featured an evil, sentient quark as a villain. He was flattening the United States one structure at at time, destroying structures by pulling out the bottom atom. He planned to turn the country into a parking lot, then flatten Canada to make room for a giant amphitheater...where he would perform. The best part was the way he was defeated...Secret pointed out that quarks are defined as hypothetical particles, so he didn't really exist. Thus, he disappeared in a puff of logic.
