Example 2.  Drives and Their Vicissitudes (concl.)

With a little thought it is possible to devise an indexing scheme for
the general run of dynamic states that allows for comparing universes
of discourse that weigh in on different scales of observation.  With
this end in sight, let us index the states q in E^m.X with the dyadic
rationals (or the binary fractions) in the half-open interval [0, 2).
Formally and canonically, a state q_r is indexed by a fract
