## Main Question or Discussion Point

If I understand correctly (no guarantee), the angles A and B in the generator of the three Pauli matrices (excluding the identity):

cos A...................exp(-iB) sin A

exp(iB) sin A.................-cos A

refer to angles in a Hilbert space, for example the angles of the Bloch sphere. However, are they at the same time the angles between the axes in which a magnetic field would be positioned in order to measure spin? Otherwise put, what is the connection between the Pauli matrices and spatial coordinates?exp(iB) sin A.................-cos A
