In the early 1900s, mathematician Emmy Noether came up with a theorem to help resolve some problems with Einstein's theory of gravity, general relativity. Little did she know it would change physics ...

Noether’s theorem is a fundamental result in physics stating that every symmetry of the dynamics implies a conservation law. It is, however, deficient in several respects: for one, it is not ...

Flawed conservation laws are consequences of a much deeper principle: Noether’s theorem. Conservation laws are among the most important tools in physics. They feel as fundamental as you can get. And ...
