  I review CP violation in the standard model (SM). I also describe the
predictions for CP violation in the B system, along with signals for physics
beyond the SM. I stress the numerous contributions of Pat O'Donnell to this
subject. Finally, I discuss a new method for measuring new-physics parameters
in B decays. This knowledge will allow us to partially identify any new physics
which is found, before its direct production at high-energy colliders.
