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:

    “Osteopath—One who argues that all human ills are caused by the pressure of hard bone upon soft tissue. The proof of his theory is to be found in the heads of those who believe it.”
    —H.L. (Henry Lewis)

    “Every theory is a self-fulfilling prophecy that orders experience into the framework it provides.”
    —Ruth Hubbard (b. 1924)

    “No theory is good unless it permits, not rest, but the greatest work. No theory is good except on condition that one use it to go on beyond.”
    —André Gide (1869–1951)
