Simultaneous measurements of position and momentum are considered in
n dimensions. We find, that for a particle whose position is strictly localized in a compact domain
(spatial uncertainty) with non-empty boundary, the standard deviation of its momentum is sharply bounded by
, while
is the first Dirichlet eigenvalue of the Laplacian on
D.
