    "abstract": "Quantum mechanics is nonlocal. Classical mechanics is local. Consequently\nclassical mechanics can not explain all quantum phenomena. Conversely, it is\ncumbersome to use quantum mechanics to describe classical phenomena. Not only\nare the computations more complex, but - and this is the main point - it is\nconceptually more difficult: one has to argue that nonlocality, entanglement\nand the principle of superposition can be set aside when crossing the \"quantum\n$\\rightarrow$ classical\" border. Clearly, nonlocality, entanglement and the\nprinciple of superposition should become irrelevant in the classical limit. But\nwhy should one argue? Shouldn\u0027t it just come out of the equations? Does it come\nout of the equations? This contribution is about the last question. And the\nanswer is: \"it depends on which equation\".",
