This principle can be stated as the variance in energy times the variance in time is greater than or equal to h-bar over 2, though its typical formulation concerns two other quantities, and the Bohr model of the atom violates this principle by assigning definite positions to electrons.
This statement realistically concerns variables that do not commute, as it defines one half the magnitude of the commutator of variables to be the limit on the product of their variances.

For 10 points, identify this principle named for a German physicist which states that, at a given instance, the position and momentum of a particle cannot both be determined precisely.
