Noether's theorem states that every differentiable symmetry of the action of a physical system with conservative forces has a corresponding conservation law. The theorem was proven by mathematician Emmy Noether in 1915 and published in 1918. Application of Noether's theorem allows physicists to gain powerful insights into any general theory in physics, by just analyzing the various transformations that would make the form of the laws involved invariant. For example the invariance of physical sys

Emmy Noether was a mathematician born in Germany in 1882 who later came to reside and do much of her work in the United States. Amazingly brilliant men of her age—including Albert Einstein—called her the most important female mathematician in history. And for a good reason!Noether basically invented abstract algebra and theoretical physics, as well as developing the rough outline of ring theory. She worked for years and years with little to no pay to study theorems and proofs in ways that the me
