How can I get the wave function

[eoghan]

Hi! In every qm exercise I have the wave at time t=0 and I have to study its evolution in time. But experimentally, how can I get the wave function at time t=0? For example, if I am studying the motion of my car, how can I get its wave function?

By solving the time independent Schrödinger equation.

By solving the time independent Schrödinger equation.

Please. The whole problem with quantum mechanics is that you can never get the wave function for t=0. It's fundamentally unknowable.

And so the problems like "given the wave function at time t=0..." aren't real?
How can I calculate the wave function associated with e.g. an electron?
Obviously I can't solve the Shrodinger equation, because to solve it I need the Fourier transform of the wave function in order to build the wave packet...
