quark

(noun)

In the Standard Model, an elementary subatomic particle that forms matter. Quarks are never found alone in nature, but combine to form hadrons, such as protons and neutrons.

Examples of quark in the following topics:

  • Binding Energy and Nuclear Forces

    • It is the attractive force that binds together particles known as quarks (to form the nucleons themselves).
    • Gluons hold quarks together with a force like that of an electric charge (but of far greater power).
    • Similarly, even though nucleons are made of quarks in combinations which cancel most gluon forces (they are "color neutral"), some combinations of quarks and gluons leak away from nucleons in the form of short-range nuclear force fields that extend from one nucleon to another nucleon in close proximity.

  • The Pauli Exclusion Principle

    • Fermions include elementary particles such as quarks (the constituent particles of protons and neutrons), electrons and neutrinos.
    • In addition, protons and neutrons (subatomic particles composed from three quarks) and some atoms are fermions and are therefore also subject to the Pauli exclusion principle.

  • Three States of Matter

    • Further states, such as quark-gluon plasmas, are also believed to be possible.

  • Brief Survey of Epistemology

    • They are shaped by special groups, cultures, civilizations; and they are shaped from a material which depending on its treatment, provides us with gods, spirits, a nature that is a partner of humans rather than a laboratory for their experiments, or with quarks, fields, molecules, tectonic plate.
