Evolving Constants of Motion
Abstract
A critical presentation of Rovelli's ``evolving constants of motion'' is given. Previous criticisms by Kuchař concerning the role of factor ordering and the non-existence of observables are dealt with and shown to be unfounded. Kuchař's criticisms that this approach does not solve the global, multiple choice or Hilbert space problems of time are confirmed, and new insight into why this is so is obtained.
