The back cover of Relativity Trail:

    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 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. Relativity Trail subsumes Einstein's treatment and reveals what is transpiring behind the scenes of Einstein's treatment. 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." Learn the secrets of clocks and rods inside the covers of Relativity Trail.

   Relativity Trail has 192 pages with
