Given suitable initial conditions [ typically, ?(x, t = 0) ], the Schr ? dinger equation determines ?(x,t) for all future time , just as, in classical mechanics, Newton ’ s law determines x(t ) for all future time. Fundamental principles of Quantum Mechanics : Assumption 1 : Wave function ?( r, t) describes the state of a particle ! Assumption 2: Schr ? dinger Equation What exactly is this “ wave function ”? or what does it do for you once you are got it ? or how can such “ wave function ” be said to describe the state of a particle ? Now, Question is: The wave function ?(r,t ) itself is complex , not any physical means, but | ?(r,t )| 2=?*? ( where ?* is the complex conjugate of ?) is real and nonnegative — as a probability , of course, must be.
