Note 46 — Chapter XIII · EINSTEIN’S SPECIAL THEORY OF RELATIVITY
Reading edition
It is necessary to take both of these conditions into account. If, for instance, we limited ourselves to the invariance of light’s velocity without taking into consideration the relativity of velocity, transformations such as ; would also satisfy our requirements, and these would not be the Lorentz-Einstein transformations and would not be in accord with the relativity of Galilean motion.
