Query: Stodolsky's Theorem and Neutrino Oscillation Phases -- for pedestrians   Neutrino oscillations are experimentally observable only as a result of
interference between neutrino states with different masses and THE SAME ENERGY.
All interference effects between neutrino states having different energies are
destroyed by the intereaction between the incident neutrino and the neutrino
detector. Erroneous results are frequently obtained by neglecting the
neutrino-detector interactions.
