**initialization**(to ensure that when the origins of the involved inertial reference frames are located at the same point in space theirs clocks read t=t'=0) and a

**synchronization of the clocks of the same inertial reference frame**ensuring that they display the same running time. The synchronization is performed following a procedure proposed by Einstein. The formula that accounts for the Doppler Effect relates two proper time intervals measured by the observers of the two reference frames respectively and can be derived using initialized clocks theirs synchronization being not compulsory. My question is: Could we derive the fundamental equations of special relativity without to synchronize the clocks of the same inertial reference frame? My oppinion is yes. Your oppinion is highly appreciated in the spirit of
