Relativity Trail
Albert Einstein, at Leyden in 1920, forcefully argued for the pertinence of Ernst Mach's notions of an object's relationship to totality and for the structure of space which imparts inertial properties and provides us with standards for our clocks and rods. In Relativity Trail, the symmetrically measured effects of Special Relativity are explained with diagrams and arithmetic in absolute terms, ending all confusion regarding relative frames of reference and revealing what is transpiring behind the scenes of Einstein's treatments of 1905 and 1916. No clock paradox arises, as the time-keeping differential between reunited clocks is seen to be caused by an actual difference in clock-rates in accordance with their different states of motion relative to the speed of light. Everything is charted out against a system at rest with respect to the totality of the universe for perfect clarity as well as soundness of theoretical basis.
