Abstract

In the traditional formalism of quantum mechanics, a simple direct proof of (a version of) the Spin Geometry Theorem of Penrose is given; and the structure of a model of the `space of the quantum directions', defined in terms of elementary SU(2)SU(2)-invariant observables of the quantum mechanical systems, is sketched.
