   Special Relativity in absolute terms ..

   .. explains what is transpiring behind 
   the scenes of Einstein's treatment.

   Relativity Trail diagrams Einstein's clock sychronization in
   absolute terms, explains the time-keeping differential, and
   diagrams symmetrical assessments across inertial frames.
   
   All the above are original works of the author and are
   unique to Relativity Trail.

   It's completely consistent with Einstein's relativity,
   diagramming and explaining it in absolute terms.

   The clock paradox (twins paradox) of special relativity 
   cannot be resolved without acknowledging an actual
   hierarchy of clock rates dependent on an actual hierarchy
   of inertial motion.  And this we do in Relativity Trail.

   Any attempt to explain an actual time-keeping differential 
   while forbidding "the actual" is doomed to fail in a purely 
   logical sense; in a purely mathematical sense.

     Relativity Trail was given a special place of honor at the 
     Science Museum of Minnesota bookstore -- front and center
     on their front table.  It was the first thing visitors saw as
     they walked through the front door.

     Relativity Trail is also available at the U of M campus bookstore.
