That electrons can be two places at the same time. Quantum mechanics is one of the largest achievements in th 20th centurty,the theory has been developed. Einstein himself hated this There are also practical implications of their work. "I think I can safely say that nobody understands quantum mechanics," spoke American physicist, educator and quote machine Richard Feynman — underlining the idea that even leading scientists struggle to develop an intuitive feeling for quantum. "Our understanding of quantum mechanics is rudimentary, at best, yet we are on the verge of developing practical quantum computers that promise virtually unlimited computational power. They proved the correctness of the bizarre properties of quantum mechanics, i.e. We won't know whether supersymmetry is real .. I'm doing this calculation for the mundane and practical purpose of helping to identify an unknown compound in a pharmaceutical dosage form. Not that we should be spending as much money trying to pinpoint a correct understanding of quantum mechanics as we do looking for supersymmetry, of course. QM is OK for FAPP, however I am not sure I want to shut up and calculate. The main concept of the theory Then in 1949 Feynman diagrams were introduced to represent terms in the QED perturbation expansion - and the rules for these rapidly became what defined QED in essentially all practical applications. It's almost as if we're taking quantum mechanics down from the philosopher's ladder and we are trying to make it practical? Bell's inequality is satisfied by the predictions of any local realistic theory, whereas quantum mechanics predicts measurement outcomes that can violate it. This new variational principle may have broad applicability in a wide range of practical and theoretical problems across multiple disciplines." -- Chad Galley (Read his article: "Losing Energy with Hamilton's Principle of Least The terms in the inequality are the correlations of measurement results. Method can be used directly in those systems in which the novel quantum technologies are to be implemented. The appropriate tools are very different. And such practical applications might eventually help to gain a better understand of quantum mechanics.
