    Graduate Why do we consider the evolution (usually in time) of a wave function ?

    Why do we consider evolution of a wave function and why is the evolution parameter taken as time, in QM. Look at a simple wave function $\psi(x,t) = e^{kx - \omega t}$. $x$ is a point in configuration space and $t$ is the evolution parameter. They both look the same in the equation, then why...
