Would you ever describe an arrow pointing to the right as pointing either up or down? If you are teaching NMR or MRI, there is a good chance you do just that, and expect your students to understand. Frequently misunderstood QM is responsible. Nuclei in thermal equilibrium are not in the spin-up or the spin-down state, for example, but in almost random mixtures (superpositions) corresponding to a near-spherical distribution of orientations. And nuclear magnetic resonance involves no "quantum jumps".

The DRCMR Reader Centre handles and processes large amounts of MRI data with effective data management and analysis methods in multiple cohort studies and clinical trials.
