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."
