Abstract

Most significant laws in science are conservation laws; for example, we may recall the laws of conservation of mass, energy, momentum, angular momentum, and charge. In physics, a conservation law states that a particular measurable property of an isolated physical system does not change as the system evolves. One particularly important physical result with regard to conservation laws is that every conserved quantity corresponds to a particular symmetry: For example, the conservation of energy follows from the time invariance of physical systems.
