Noether's theorem

Her 1913 result on the calculus of variations, leading to Noether’s Theorem is considered one of the most important theorems in mathematics—and one that shaped modern physics.

Noether's theorem makes a connection between symmetry principles and conservation laws—it shows that for every form of symmetry, there is a corresponding quantity that is conserved.

In the application relevant here, Noether's theorem states that τ is basically equivalent to the conservation of energy.

Noether’s theorem remains highly relevant because symmetries are at the forefront of the search for deeper truths in physics.

Eastern Time, mathematician Peter Olver will discuss Noether’s life and career, and physicist Ruth Gregory will detail the meaning of Noether’s theorem.
