Noun
uncertainty principle
(quantum mechanics) The Heisenberg uncertainty principle.
Quantum mechanics brought an unexpected fuzziness into physics because of quantum uncertainty, the Heisenberg uncertainty principle. Edward Witten
Both the uncertainty principle and the negentropy principle of information make Laplace's scheme [of exact determinism] completely unrealistic. The problem is an artificial one; it belongs to imaginative poetry, not to experimental science. Léon Brillouin
Quantum mechanics brought an unexpected fuzziness into physics because of quantum uncertainty, the Heisenberg uncertainty principle. String theory does so again because a point particle is replaced by a string, which is more spread out. Edward Witten
Also, discrete wavelet bases may be considered in the context of other forms of the uncertainty principle. Source: Internet
Below is an illustration of wave–particle duality as it relates to De Broglie's hypothesis and Heisenberg's uncertainty principle (above), in terms of the position and momentum space wavefunctions for one spinless particle with mass in one dimension. Source: Internet
By the time–energy uncertainty principle, they do not have a definite energy, and, each time they decay, the energy they release is slightly different. Source: Internet
