Proving uncertainty: First rigorous formulation supporting Heisenberg's famous 1927 principle > http://phys.org/news/201404uncertaintyrigorousheisenbergfamousprinciple.html
> Nearly 90 years after Werner Heisenberg pioneered his uncertainty > principle, a group of researchers from three countries has provided > substantial new insight into this fundamental tenet of quantum > physics with the first rigorous formulation supporting the > uncertainty principle as Heisenberg envisioned it.
> In the Journal of Mathematical Physics, the researchers reports a new > way of defining measurement errors that is applicable in the quantum > domain and enables a precise characterization of the fundamental > limits of the information accessible in quantum experiments. Quantum > mechanics requires that we devise approximate joint measurements > because the theory itself prohibits simultaneous ideal measurements > of position and momentum?and this is the content of the uncertainty > relation proven by the researchers.
