Query: Theories of Non-Experiments in Coherent Decays of Neutral Mesons   Many theoretical calculations of subtle coherent effects in quantum mechanics
do not carefully consider the interface between their calculations and
experiment. Calculations for gedanken experiments using initial states not
satisfied in realistic experiments give results requiring interpretation.
Confusion and ambiguities frequently arise. Calculations for time-dependent
mixing oscillations describe non-experiments. Physical experiments describe
oscillations in space in the laboratory system resulting from interference
between waves having the same energy and time dependence; $not$ different
momenta and space dependence. Time-dependent oscillations are not observed.
