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 never comes a point where a theory can be said to be true. The most that one can claim for any theory is that it has shared the successes of all its rivals and that it has passed at least one test which they have failed.”
    —A.J. (Alfred Jules)

    “The human species, according to the best theory I can form of it, is composed of two distinct races, the men who borrow and the men who lend.”
    —Charles Lamb (1775–1834)

    “It is not enough for theory to describe and analyse, it must itself be an event in the universe it describes. In order to do this theory must partake of and become the acceleration of this logic. It must tear itself from all referents and take pride only in the future. Theory must operate on time at the cost of a deliberate distortion of present reality.”
    —Jean Baudrillard (b. 1929)
