November 17
``Why does time flow forward?'' Jim asks.
Tom replies, ``It doesn't.  Time just is; it doesn't move any more
   than the city of Chicago moves.  November 17 is a point in time like
   Chicago is a point in space.''
``But don't we move in time?  And aren't we always moving forward?''
``At every instant, we are only in one place.  It only appears to us
   that we are moving forward because we remember the past and we
   don't remember the future.''
``Then we could change this if we found some way to know the future!''
   exclaims Jim.  He suggests consulting the engineers at Sophist and
   changing the operation of the machine again.  Once more, the
   engineers are able to do something.  Now the time machine works so
   that only the contents go back in time, not the outside world.
   Jim intends to go a day into the future.  He will discover what
   will happen to Tom.  He can tell Tom, who will then have memory of
   the future, and the flow of time will be reversed.  Or at least
   confused.
