Observational Derivation of Einstein's``Law of the Constancy of the Velocity of Light in Vacuo"
arXiv:physics/0510127 · doi:10.1063/1.2158746
Abstract
On the basis of Galilean invariance and the Doppler formula, combined with an observational condition, it is shown that the constancy of the velocity of light {\it in vacuo} can be derived, together with time-dilatation and Lorentz contraction. It is not necessary to take the constancy as a postulate.
