General Relativity Einstein`s Theory of Gravity Paul Woodward
... In Galileo’s world, and also in the world of special relativity, a straight line is the path followed by an object moving at a constant velocity and not acted upon by any force. This definition, of course, is circular, since when turned around it is also the definition of a constant velocity. At lea ...
