You want to measure the position of an electron within 5 x 10-11 m. An electron is moving at a speed of 5.0 x 106 m/s.This uncertainty is very significant when applied to atomic and subatomic particles.

This indicates the limit of the accuracy of trying to simultaneously determine both an electron’s position and momentum.If the minimum uncertainty (precision) in x is defined as Δx, and that of p is Δp: (Δx)(Δp).
