ALL meanings of uncertainty principle
un·cer·tain·ty prin·ci·ple
U u - noun uncertainty principle the principle of quantum mechanics, formulated by Heisenberg, that the accurate measurement of one of two related, observable quantities, as position and momentum or energy and time, produces uncertainties in the measurement of the other, such that the product of the uncertainties of both quantities is equal to or greater than h/ 2 π, where h equals Planck's constant. 1
- noun uncertainty principle the principle that energy and time or position and momentum of a quantum mechanical system, cannot both be accurately measured simultaneously. The product of their uncertainties is always greater than or of the order of h, where h is the Planck constant 0
- noun uncertainty principle in quantum mechanics, the principle that it is impossible to measure simultaneously and exactly two related quantities, as both the position and the momentum of an electron 0
- noun uncertainty principle (quantum mechanics) Heisenberg uncertainty principle. 0
