Query: CP and T Violation in Neutrino Oscillations   In this short lecture, we discuss some basic phenomenological aspects of CP
and T violation in neutrino oscillation. Using CP/T trajectory diagrams in the
bi-probability space, we try to sketch out some essential features of the
interplay between the effect of CP/T violating phase and that of the matter in
neutrino oscillation.
