    "abstract": "It is shown that Schrodinger dynamics can be embedded in a larger dynamical\ntheory which extends its symmetry group from the unitary group to the full\nmetaplectic group, i.e. the group of linear canonical transformations. Among\nthe newly admitted non-unitary processes are analogues of the classical\nmeasurement process which makes it possible to treat the wave-function as an\nobjective property of the quantum mechanical system on the same footing as the\nphase-space coordinates of a classical system. The notion of \"observables\" that\nin general have values only when measured can then be dispensed with, and the\nmeasurement paradox disappears.",
