Of course, you are right.  I guess I used the term "inertial
balance" incorrectly.  What I had in mind was the standard lab-
type balance beam to which earlier discussion had referred.  But
why should the kind of device you are talking about be called a
"balance"?  What's being balanced?  I think I'll call it an
"inertial bounce."
