The Wave Function
... The Heisenberg relation has an immediate interpretation. It tells us that we cannot determine, from knowledge of the wave function alone, the exact position and momentum of a particle at the same time. In the extreme case that ∆x = 0, then the position uncertainty is zero, but Eq. (3.14) tells us th ...
