I'm having a bit of trouble understanding the uncertainty equation, why is it that the more certain you are about the momentum, the less certain you are about the position? Thank you!

If you look at Heisenberg's Uncertainty Equation (uncertainty in position)(uncertainty in momentum) = a constant, therefore the two are inversely proportional to each other. This means that the more certain you are about one of the variables, the less you are about the other.

It is like a reciprocal process that since the electron's path will be deflected, if you know the p, then you won't know where it will be. if you know its position, then you won't know its p

Thank you so much, your answer really helped. It is much easier to remember and think of this as a reciprocal process
