Information about Conservation Laws

For information on the legal aspects of environmental conservation, see conservation movement.
In physics, a conservation law states that a particular measurable property of an isolated physical system does not change as the system evolves. Any particular conservation law is a mathematical identity to certain symmetry of a physical system. A partial listing of conservation laws that are said to be exact laws, or more precisely have never been shown to be violated:
  • Conservation of energy
  • Conservation of linear momentum
  • Conservation of angular momentum
  • Conservation of electric charge
  • Conservation of color charge
  • Conservation of probability
There are also approximate conservation laws. These are approximately true in particular situations, such as low speeds, short time scales, or certain interactions.

A chiral anomaly is the anomalous nonconservation of a chiral current. In some theories of fermions with a chiral symmetry the quantization may lead to the breaking of this (global) chiral symmetry. In that case, the charge associated with the chiral symmetry is not conserved.
