This year is the centennial of Noether’s theorem, which is often called the most beautiful result in mathematical physics. Developed by Amalie Emmy Noether (1882-1935), the theorem resolves questions ...

Emmy Noether showed that fundamental physical laws are just a consequence of simple symmetries. A century later, her insights continue to shape physics. In the fall of 1915, the foundations of physics ...

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 ...
