A SYNOPSIS
The BOOK presents for the very first time the correct use of
Galilean Transformations of Velocities
in the framework of
Euclidean Space Geometry
A Serious Omission from the Textbooks
map to correct explanations to solutions to
Gravitation and Electromagnetism
The Evidence  
Theoretical
The complete set of problems responsible for the success and fame of Relativity was solved without having to resort to Relativity (The Book, "Discourses & Mathematical Illustrations pertaining to the Extinction Shift Principle...") 

Experimental
The constancyofthevelocityoflight experiments in optics, performed in the past century, were completely explained along with correctly predicted experimental outcomes, using the Principal Axioms of the Extinction Shift Principle alone under Galilean Transformations of Velocities (Appendix of Book, "Principal Axioms") 

Distorted Space Geometry  Euclidean Space Geometry 
Lorentz
Transformations of Velocities
units of length {x, y, z} are modified unit of time {t} is dilated 
Galilean
Transformations of Velocities
units of length are true/undistorted observer notes a transverse relative time shift 
Velocity of all emissions is constant in all frames of reference 
Velocity of all emissions is constant relative only to the most primary source 
No distinction is made between the states of a wave before and after measurement  A direct observation or measurement on an undisturbed primary wave is denied 
The wavelengths and the velocities of all emissions are considered to be measurable; erroneous concept currently taught in mainstream Physics  Neither the primary velocity nor the primary wavelength of an undisturbed primary wave is measurable; only the ratio {energy} is an observable 
The
wavelength is frame dependent
Distinction is never made between the primary and seconary emissions 
The notmeasurable wavelength of a primary wave is independent of reference frames
