These connections between symmetries and conservation laws of a dynamical system are expressed by the Noether's theorem [61].
After her work with abstract algebra, Noether began studying physics, which led to her greatest discovery: Noether's Theorem. This theorem basically states that any system in symmetry can be explained by a law of conservation.
