Point-of-View Invariance and Noether’s Theorem

Noether's theorem is an important theorem that relates invariance of space-time transformations to the laws of conservation: space-translation invariance to the conservation of linear momentum, space-rotation invariance to the conservation of angular momentum, and time-translation invariance to the conservation of energy. The models of physics are point-of-view invariant: physical models cannot depend on any particular position in space or moment in time.
