The Source of Magic in the Quantum World

It has been frequently said that “Quantum Mechanics is Magic”. !e real fact is just the opposite: quantum mechanics is not magic, it is rather one of the best scienti"c theories in terms of the amplitude and exactness of its predictions. Quantum Mechanics surprises us as it does not satisfy some a priori principles usually considered to be necessary preconditions to build up physics (as Einstein dixit). As these principles are also the basis of some important philosophical theories of science, these philosophical theories cannot be well founded. After criticizing them, we other the preliminary lines of a methodology of physics adapted to the formalism of quantum mechanics.
