[QUOTE="vanhees71, post: 5471324, member: 260864"] I cannot repeat it often enough. The usual Heisenberg-Robertson uncertainty relation is about the impossibility to PREPARE a particle in a state that represent the particle to have a sharp position in one direction and a sharp momentum in the same direction, ##\Delta x_j \Delta p_k \geq \hbar \delta_{jk}/2##. It does not prevent you from measuring position or momentum as accurately as you like. In fact, to check the uncertainty relation you need an ensemble of equally prepared particles and do a position measurement with a much larger accuracy than ##\Delta x## and an ensemble with the same properties to make a momentum measurement with a much larger accuracy than ##\Delta p##.
