Einstein’s special theory of relativity investigated -
After more than 100 years, the confusion regarding Einstein’s
second postulate remains widespread, with Einstein himself
never weighing in on the controversy he created. Upon the
correct form of this second postulate depends our ability to
understand what is imparting inertial properties, what is
generating the relations of relative uniform motion and to
diagram the motions and measurement taking of special
relativity in a concrete, rather than abstract manner.
Relativity Trail is primarily devoted to the restoration of
Einstein's initial wording of his second postulate, along with
the universal character of the reference frame it implies,
without introducing an aether or any other immutable frame.
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 contradiction in the clock paradox,
why mass varies with motion, why E = mc2, and with:
a straightforward derivation of the Lorentz transformations,
and much more.

A goal of any science book should be the avoidance of abstractions
as deeply into structures as possible. 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.
The exact process by which parties take measure of each other is
fully described, using only the familiar diagrams and arithmetic of
a customary stationary reference frame, the existence 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 Lorentz or of the aether.
