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:

    “[Anarchism] is the philosophy of the sovereignty of the individual. It is the theory of social harmony. It is the great, surging, living truth that is reconstructing the world, and that will usher in the Dawn.”
    —Emma Goldman (1869–1940)

    “The great tragedy of science—the slaying of a beautiful theory by an ugly fact.”
    —Thomas Henry Huxley (1825–1895)

    “By the “mud-sill” theory it is assumed that labor and education are incompatible; and any practical combination of them impossible. According to that theory, a blind horse upon a tread-mill, is a perfect illustration of what a laborer should be—all the better for being blind, that he could not tread out of place, or kick understandingly.... Free labor insists on universal education.”
    —Abraham Lincoln (1809–1865)
