Q4: Consider the following descriptions of two events:
The place and time where/when Peter *observes* the second hand on
his watch to have made one complete revolution.
The place and time where/when the second hand on Peter's watch
*has* made one complete revolution.
Are these descriptions of the same event (within a trivial
uncertainty of about 3 feet and/or 3 microseconds) or not?
The only real problem with the original question, IMO, is that it is not
100% clear that Peter is moving and Jane is at rest although that (again
to me) is clearly the intent.
Of course this is not the first (or last) time a topic that started out
as a discussion for a H.S. or College intro course has turned into a
free-for-all at the theoretical dissertation level. ;-)
