Einstein, relativity, equations, c-v
In his paper “On the Electrodynamics of Moving Bodies”, Albert Einstein used the term “c – v” in order to construct the fundamental basis of the Special Theory of Relativity. This is an important term, as he used c – v or (c – v) 2 several times in the process of developing the Lorentz factor. Appearing first in §2 of his paper , c – v corresponds to the “velocity” contained in Einstein’s expression “velocity = light path ÷ time interval ”. However, a close examination of c – v together with his conclusion in §2 of the paper , we will find that c – v is not usable for dividing the “light path” in his expression.
