quark -
(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; "quarks have not been observed directly but theoretical predictions based on their existence have been confirmed experimentally"
quark -
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.
quark -
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.
Wikipedia
A quark 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 found in isolation; they can only be found within hadrons.
