negare-ye klâsik-e meydân

Fr.: théorie classique des champs

The theory that studies distributions of → energy, → matter, and other physical quantities under circumstances where their discrete nature is unimportant. Classical field theory traditionally includes → Newtonian mechanics, Maxwell’s → electromagnetic theory, and Einstein’s theory of → general relativity.
The main scope of classical field theory is to construct the mathematical description of → dynamical systems with an infinite number of degrees of freedom. The word “classical” is used in contrast to those field theories that incorporate → quantum mechanics (→ quantum field theory). Classical field theories are usually categorized as → non-relativistic and → relativistic.

See also: → classical; → field; → theory.
