uncertainty principle
(Heisenberg uncertainty principle)
subjectfact 
uncertainty principlehas implication the microscopic realm is a roiling frenzy, awash in a violent sea of quantum fluctuations.has source: Greene, B. 1999 The Elegant Universe, W.W. Norton and Co., New York, 2001-09-27 09:33:54.0
has corollary it is impossible to measure an atomic or nuclear process without at the same time disturbing or altering the process.has source: Hopkins, J. 1976 Glossary of Astronomy and Astrophysics, University of Chicago Press, 2001-09-27 09:33:54.0

has example the uncertainty in the measurement of the position of an electron varies inversely as the uncertainty in the measurement of its momentum.has source: Hopkins, J. 1976 Glossary of Astronomy and Astrophysics, University of Chicago Press, 2001-09-27 09:33:54.0
has definition The principle that the fundamental uncertainty in a variable times that in its canonical conjugate is of the order of Planck's constant.has source: Hopkins, J. 1976 Glossary of Astronomy and Astrophysics, University of Chicago Press, 2001-09-27 09:33:54.0
