spontaneous symmetry breaking

   Also found in: Wikipedia 0.01 sec.
spontaneous symmetry breaking [spän′tā·nē·əs ′sim·ə·trē ‚brāk·iŋ]
(physics)
A situation in which the solution of a set of physical equations fails to exhibit a symmetry possessed by the equations themselves; an example is a magnet, in which the underlying equations describing the metal do not distinguish any direction of space from any other, but the magnet certainly does, since it points in some definite direction.
