Does the RST include the classical laws of physics (mechanics)?
Yes. The classical laws of physics have emerged from Newton’s program of research, which has been historically interpreted as a dictum to focus on forces. However, the measurement and understanding of these forces, as a function of the change in location of objects, defining the motion of objects, depends on the frame of reference in which they are viewed, the motion of which also must be taken into account. When various transformations from one reference system to another are applied, laws of conservation emerge that ensure us that physical principles are universally inviolate. This understanding of the “invariance” of physical law under reference system transformation worked very well until the high-speed and unusual properties of radiation were found that required a new definition of motion. Lacking the new definition, the results of invariance have been misinterpreted, leading to incorrect physical concepts. The RST clarifies these concepts.
