Best wishes for the new year 2019 and a delightful quantum rapture!
Mathematical physics is based on a protocol of articulation of the geometric and the physical meanings. Why then prefer the certainty that I can close my fist on the electron which is there before me by the simple knowledge of its position-speed to the richness of the algebra of the observables which says much more about the experimental game: symmetry, compatibility of certain practices, rules of the set of measurements. The uncertainty relations are to be apprehended as the mere refusal of the physical world to give itself by Cartesian (commutative) seizure. This one is powerless to understand the roles, the places, the intrigues of the quantum theater.
