(Phys.org)—Werner Heisenberg originally proposed the uncertainty principle in 1927,but his original proposal was somewhat different than how it is interpreted nowadays. As a recent paper in Physical Review Letters explains, Heisenberg's original statement was about error and disturbance in a measurement process. Over the years, and however,Heisenberg's original proposal has been restated in terms of the uncertainties intrinsic to quantum states. This aspect of the uncertainty principle has been studied extensively with well-developed theories and verified experimentally.
