# What is Wave Mechanics

The modern form of quantum theory; an extension of quantum mechanics based on Schrodinger’s equation; atomic events are explained as interactions between particle waves.

**T**he branch of quantum physics that accounts for matter at the atomic level; an extension of statistical mechanics based on quantum theory (especially the Pauli exclusion principle).

In classical mechanics, the equation of motion is Newton’s second law, (**F** = *m***a**), used to mathematically predict what the system will do at any time after the initial conditions of the system. In quantum mechanics, the analogue of Newton’s law is Schrodinger’s equation for a quantum system (usually atoms, molecules, and subatomic particles whether free, bound, or localized). It is not a simple algebraic equation, but in general a linear partial differential equation, describing the time-evolution of the system’s wave function (also called a “state function”).
