Amalie Emmy Noether was a German mathematician known for her landmark contributions to abstract algebra and theoretical physics. And noether’s theorem is one of the most beautiful equation in all of theoretical physics.
The theorem explains the connection between symmetry and conservation laws.
It is remarkably surprising that there are a lot of people who are not aware of Noether’s contribution to physics.
This video by ‘Looking Glass Universe’ does a good job (but does not cover the math) in explaining the essence of the theorem.
