### Complementarity of Location and Momentum

Why is it that its impossible to know the position if the momentum is known precisely?

### Re: Complementarity of Location and Momentum

I think during lecture, Professor Lavelle mentioned that when photons interact with electrons, this interaction will affect the position AND momentum of the electron, so the momentum would not be precisely known. Because we don't know the pathway of the electron, the velocity would change therefore the momentum would be uncertain.
