s pecial principle of relativity. Its s ignificance lay in its as s ertion that abs olute Galilean m otion or abs olute
velocity m us t ever es cape all experim ental detection. Henceforth abs olute velocity s hould be conceived of as
phys ically m eaningles s , not only in the particular realm of m echanics , as in Newton's day, but in the entire
realm of phys ical phenom ena. Eins tein's s pecial principle, by adding increas ed em phas is to this relativity of
velocity, m aking abs olute velocity m etaphys ically m eaningles s , created a s till m ore profound dis tinction
between velocity and accelerated or rotational m otion. This latter type of m otion rem ained abs olute and real as
