    The back cover:

    Einstein's special theory of relativity, in absolute terms -

    In special relativity, one makes his measures using clocks,
    measuring rods and light beams.  Einstein's two postulates of 
    special relativity, as used in his treatment, address only what 
    measurements one shall arrive at.

    In Relativity Trail, you'll be introduced to the absolute form
    of these postulates, which addresses the absolute nature of 
    things, particularly - clocks, rods and light beams themselves.

    Upon the absolute form of these postulates depends our ability 
    to understand what is generating the mutual effects of relative 
    uniform motion and, identically, what has created the time 
    differential between reunited clocks.  

    In Relativity Trail, we faithfully diagram Einstein's special
    theory against an absolute frame of reference which is intrinsic
    to the evolving structure of our universe.

    In so doing, Relativity Trail provides its readers with a 
    clear description of: 
  • what time keeping is
  • why time keeping and lengths of rods vary with motion
  • why all inertial frames are effectively equivalent
  • why there is no clock paradox
  • why mass varies with motion
  • why E = mc2
and much more. Relativity Trail provides a straightforward derivation of the Lorentz transformations.
    A goal of any science book should be the relegation of 
    abstractions to the deepest level of structures.  
    Relativity Trail is all about freeing the study of 
    relative motion from abstractions, so as to allow us to diagram
    exactly what is transpiring in matters of clock functioning and
    length determination.  Measuring processes are fully described,
    using only the familiar diagrams and arithmetic of a customary
    stationary reference frame, the pertinence of which is clearly
    demonstrated in this book.

    Relativity Trail is completely consistent with Einstein's
    special theory of relativity, with its effective equivalence of
    all inertial frames.  It is not the relativity of the aether or
    of variable light speed.     

    From Relativity Trail:

    "J.R. Lucan and P.E. Hodgson argue that Einstein offered a new
    "Gestalt", "a new view of what really was the case, and not
    merely a convenient convention for talking about relations
    between the motions of ordinary material bodies" ... "thus we
    should see length itself altered, instead of thinking of objects
    suffering a Lorentz contraction".

    But such labels and suggestions of what "we should see" as
    reality do not offer any weight at all against the evidence we
    actually do see, which is the time differential between reunited
    clocks.  Such differential shows that we can understand the
    God's eye view of reality."
