   Special Relativity explained in absolute terms -
   eliminates the twin paradox, shows Einstein's clock sychronization
   diagrammed in absolute terms, and ends all confusion regarding
   relative frames of reference.  Completely compatible with, and in
   fact subsumes, Einstein's relativity.  Not Lorentzian relativity.
   Relativity Trail reveals what is transpiring behind the scenes 
   of Einstein's treatment.

   The Science Museum of Minnesota bookstore gave this book
   a special place of honor, upright and center, on their front table.
   It was the first thing visitors saw walking through the door.

   Overview (read this first): "Twin Paradox in Relativity"

   Relativity Trail   cite  /  annotation


This book grew out of the author's development, from scratch, 
of special relativity using two postulates fundamentally 
different from Einstein's.  This treatment of special 
relativity eliminates the Twins Paradox.

The back cover of Relativity Trail :

    The 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 the 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.

   Purchase your trade paperback of Relativity Trail
   at the University of Minnesota online Bookstore

   or at the University of Minnesota Bookstore 
   in Coffman Memorial Union on the East Bank campus.

   You can download the PDF of Relativity Trail below
   if you care to peruse the book before purchasing it.

   Before downloading Relativity Trail, 
   you should read this introductory document:

   Overview: "Twin Paradox in Relativity"

   Relativity Trail displays well in single page
   PDF format.  Thus either "display A" or "display B"
   below will work well.  But to simulate the paperback
   version of the book, note the following:

       PDF readers are not consistent with each other 
       regarding the way they display documents which 
       incorporate "facing pages" ("two page display").
       (They mix up left and right pages.)

       Even different versions of Adobe Reader (Adobe Acrobat)
       are not consistent with each other.

       Therefore, Relativity Trail comes in two PDF versions -
       one which displays correctly in some PDF readers,
       and one which displays correctly in the others.

       It is unpredictable as to which PDF file works in
       which PDF reader.  Try one of the PDF files below.
       If the left - right page display is incorrect for
       your PDF reader, then open or download the other
       PDF file below.

   If you don't have an up to date Internet Exlorer,
   you might need to use Google Chrome, Firefox, 
   or Microsoft Edge browser to open and then save 
   the PDF file.
