Imagine a juggler tossing balls into the air. The art of juggling is a dance between motion and pause, where the ball’s speed slows as it ascends, and then quickens on the way down. This dance reveals ...

This article is a theoretical investigation of generalized Noether's theorem, which, though unconcerned with considerations such as coordinate transformations, symmetry, and invariance, is the basic ...

Can you chip in? As an independent nonprofit, the Internet Archive is fighting for universal access to quality information. We build and maintain all our own systems, but we don’t charge for access, ...

Isabel Rabey reviews Einstein’s Tutor: the Story of Emmy Noether and the Invention of Modern Physics by Lee Philips In his debut book, Einstein’s Tutor: the Story of Emmy Noether and the Invention of ...

Emmy Noether’s groundbreaking theorem transformed physics by linking symmetry to conservation laws. If you were drifting alone through the vast emptiness of deep space and hurled a rock into the void, ...

Emmy Noether was a mathematician who discovered perhaps the most profound idea in contemporary physics. Noether’s theorem, which she formulated in 1915, says that symmetries in the universe give rise ...

Emmy Noether is responsible for an idea so important that it ranks alongside Charles Darwin’s concept of evolution by natural selection as a central and unifying principle in science. It made possible ...

In the fall of 1915, the foundations of physics began to crack. Einstein’s new theory of gravity seemed to imply that it should be possible to create and destroy energy, a result that threatened to ...

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 ...
