Silagadze %J Latin-American Journal of Physics Education %D 2012 %I Instituto Polit¨Ścnico Nacional, Latin American Physics Education Network %X Non-commutativity of the Einstein velocity addition, in case of non-collinear velocities, seemingly gives rise to a conflict with reciprocity principle. However, Thomas rotation comes at a rescue and the paradox is avoided. It is shown that such a resolution of the so called Mocanu paradox is completely natural from the point of view of basic premises of special relativity. %K Physics Education %K Special relativity %K Thomas rotation %K Mocanu paradox %U http://www.lajpe.org/mar12/13_LAJPE_627_Zurab_Silagadze_preprint_corr_f.pdf
