Out of the four papers published by Einstein in 1905, first, second and fourth papers have been based on the Thermodynamic model by virtue of the fact that emission and absorption of quanta of energy being considered as the agency of change. However, in the third paper, ‘On the Electrodynamics of Moving Bodies’, he seems to have been compelled to abandon the thermodynamic model, mainly because of his inability to demonstrate how an electric force and a magnetic force emerge spontaneously when an electron is in motion by using this model. If one cannot demonstrate the emergence of these forces, then the easiest way out is the denial of their emergence. Although it is impossible that Einstein did not realize that the parallel of his “theorem of impossibility of the perpetuum mobile” in thermodynamics would be the “theorem of impossibily of inertial motion” in mechanics, for the purpose of this denial, Einstein seems to have opportunistically taken refuge in the paradigm that had been formulated in the late nineteenth century in regard to the condition of validity of Newtonian mechanics. The paradigm is that Newton’s laws are realized only in inertial frames and that no forces are produced by a body in inertial motion.
