Uncertainty principle

Half ℏ


Heisenberg’s uncertainty principle is a fundamental property of quantum systems, not merely a limit to how small a thing we can measure.

The illustration represents the work of Earle Hesse Kennard and Hermann Weyl. The standard deviation of position (sigma sub-x) multiplied by the standard deviation of momentum (sigma sub-p) is greater than or equal to half the reduced Planck constant.
