Invariant (physics) - Wikipedia
In theoretical physics, an invariant is an observable of a physical system which remains unchanged under some transformation. Invariance, as a broader term, also applies to the no change of form of physical laws under a transformation, and is closer in scope to the mathematical definition. Invariants of a system are deeply tied to the symmetries impo… See more
Informal usageIn the field of physics, the adjective covariant (as in covariance and contravariance of vectors) is often used informally as a synonym for "invariant". For example, the Schrödinger equation does not keep its written for… See more
