Quantum Chromodynamics - Theory

Theory

List of unsolved problems in physics
QCD in the non-perturbative regime:
  • Confinement: the equations of QCD remain unsolved at energy scales relevant for describing atomic nuclei. How does QCD give rise to the physics of nuclei and nuclear constituents?
  • Quark matter: the equations of QCD predict that a plasma (or soup) of quarks and gluons should be formed at high temperature and density. What are the properties of this phase of matter?

Famous quotes containing the word theory:

    “There could be no fairer destiny for any physical theory than that it should point the way to a more comprehensive theory in which it lives on as a limiting case.”
    —Albert Einstein (1879–1955)

    “A theory of the middle class: that it is not to be determined by its financial situation but rather by its relation to government. That is, one could shade down from an actual ruling or governing class to a class hopelessly out of relation to government, thinking of gov’t as beyond its control, of itself as wholly controlled by gov’t. Somewhere in between and in gradations is the group that has the sense that gov’t exists for it, and shapes its consciousness accordingly.”
    —Lionel Trilling (1905–1975)

    “It makes no sense to say what the objects of a theory are,
    beyond saying how to interpret or reinterpret that theory in another.”
    —Willard Van Orman Quine (b. 1908)
