What is symmetry breaking?

Symmetry Breaking

Symmetry breaking in physics describes a phenomenon where (infinitesimally) small fluctuations acting on a system which is crossing a critical point decide the system's fate, by determining which branch of a bifurcation is taken. To an outside observer unaware of the fluctuations (or "noise"), the choice will appear arbitrary. This process is called symmetry "breaking", because such transitions usually bring the system from a disorderly state into one of two definite states. Symmetry breaking is supposed to play a major role in pattern formation.

Famous quotes containing the words breaking and/or symmetry:

    Worldly faces never look so worldly as at a funeral. They have the same effect of grating incongruity as the sound of a coarse voice breaking the solemn silence of night.
    George Eliot [Mary Ann (or Marian)

    What makes a regiment of soldiers a more noble object of view than the same mass of mob? Their arms, their dresses, their banners, and the art and artificial symmetry of their position and movements.
    George Gordon Noel Byron (1788–1824)
