Thanks guys, those answers help a lot! So what I understand is that in PRACTICE, the wave function will have some uncertainty built into it, so the resulting function in position space will still be a superpostion of the momentum eigenfunctions. What I'm really struggling with is how multiple...

If one measures a system for momentum, it will collapse into a delta in momentum space. (right?) How would that look in position space, and how would the function evolve in time, if no subsequent measurements are made, in both position and momentum space? A mathematical answer would be appreciated.
