Noether's theorem (1918) states that any differentiable symmetry of the action of a physical system has a corresponding conservation law. Noether's theorem has become a fundamental tool of modern theoretical physics and the calculus of variations. A generalisation of the seminal formulations on constants of motion in Lagrangian and Hamiltonian mechanics (1788 and 1833, respectively), it does not apply to systems that cannot be modeled with a Lagrangian; for example, dissipative systems with continuous symmetries need not have a corresponding conservation law.

Noethers sats (1918) anger att någon differentierbar symmetri av ett fysiskt systems handling har en motsvarande bevarandelag. Noethers sats har blivit ett grundläggande verktyg för modern teoretisk fysik och variationskalkylen. En generalisering av de seminala formuleringarna på rörelsekonstanter i Lagrangisk respektive Hamiltonsk mekanik (1788 respektive 1833), gäller det inte system som inte kan modelleras med en Lagrangisk; till exempel behöver dissipativa system med kontinuerliga symmetrier inte ha en motsvarande bevarandelag.
