What did Emmy noether contribute to math?

Answer 1

The Noether Theorem is normally quoted to derive the Law of Conservation of Energy.

It is some very advanced math, but it basically states that for every law of symmetry in nature, there is a corresponding conservation law. For example:

• The fact that the laws of nature are the same at different times is related with the Law of Conservation of Energy (either one can be derived from the other, I believe).
• The fact that the laws of nature are the same in different places is related with the Law of Conservation of Momentum.
• The fact that the laws of nature are the same in different orientations is related with the Law of Conservation of Rotational Momentum.
