In this talk I ask why, after more than ninety years, the formulation of quantum mechanics is still a matter of controversy. My aim is to provide a minimal formulation of nonrelativistic quantum mechanics that is clear and unambiguous. It will be based on the formulation of classical mechanics which is noncontroversial. The essential difference between classical and quantum mechanics is that in the latter the Euclidean phase space of states and properties is replaced by Hilbert space. The full content of quantum mechanics follows inevitably from this one assumption, including quantum incompatibility, entanglements and an understanding of the so-called measurement problem.
