Given a set of known initial conditions, Newton's second law makes a mathematical prediction as to what path a given physical system will take over time. The Schrödinger equation gives the evolution over time of a [wave function](https://en.wikipedia.org/wiki/Wave_function), the quantum-mechanical characterization of an isolated physical system.
