Query: Prediction in Quantum Cosmology   Lectures by the author at the 1986 Cargese summer school modestly corrected
and uploaded for greater accessibility. Some of the author's views on the
quantum mechanics of cosmology have changed from those presented here but may
still be of historical interest. The material on the Born-Oppenheimer
approximation for solving the Wheeler-DeWitt equation and the work on the
classical geometry limit and the approximation of quantum field theory in
curved spacetime are still of interest and of use.
