Relativity and space-time measurements

The new reconstruction of special relativity (SR) is presented. The question of length and time measurements forms the basic plane of our search. The question why Milne's procedure, applied to clocks synchronization by means of light signal, supersedes the Einsteinian procedure by means of moving clock, is elaborated. According to H. E. Ives' hints the consistency of velocity notion in SR is reanalysed. The justification of the light postulate from the point of view of measurement procedures and anti-absolutistic heuristics of SR is discussed. The new correspondence relation between SR and Ives' space-time theory is presented. The fundamental problems related to operationistic interpretation of SR and to research programmes of kinematics are discussed in the new theoretical fashion.
