unified field theory definition

Any theory in which two seemingly different forces are seen to be fundamentally identical. Maxwell's equations express a unified field theory that demonstrates the basic identity of electricity and magnetism, and the standard model postulates a basic identity for the strong force, the weak force, and electromagnetism.
