in the 
-coordinate of a particle's position, and the uncertainty 
in the corresponding momentum component, by the relationship: 
where 
is Planck's constant. [P10.2, P10.3]
imposes: a fundamental limitation on the combined precision with which certain pairs of observables can be simultaneously determined. [P10.2, P10.3, P11.1]
can be regarded: as a consequence of the wave nature of matter. [P10.2, P10.3]
is exemplified: for the uncertainty in the -coordinate of a particle's position, and the uncertainty in the corresponding momentum component, by the relationship: where is Planck's constant. [P10.2, P10.3]
is also exemplified: by the relationship 
between the uncertainties in a measurement of energy and the time taken to make the measurement. [P10.2, P10.3, P11.1]
has nothing to do: with the methods employed to make the measurements. [P10.2, P10.3, P11.1]
