A brief and transparent derivation of the Lorentz-Einstein transformations via thought experiments
arXiv:physics/0602054
Abstract
Starting with a thought experiment proposed by Kard, which derives the formula that accounts for the relativistic effect of length contraction, we present a "two line" transparent derivation of the Lorentz-Einstein transformations for the space-time coordinates of the same event. Our derivation make uses of Einstein's clock synchronization procedure
