imple uncertainty is the absence of certainty. Certainty was a postulate from the earliest times in such fields as logic, mathematics, and physics. In the late nineteenth century, the work of Frege and others cast doubts on logical certainty. In the nineteen-thirties, Gödel called mathematical certainty into question for all but the simplest systems of arithmetic. Physical uncertainty today is the consequence of Werner Heisenberg's Uncertainty Principle in quantum mechanics. It states that the exact position and momentum of an atomic particle can only be known within certain (sic) limits. The product of the position error and the momentum error is greater than or equal to Planck's constant h.
