The Semantics of ‘Time’

Our consideration of the meaning of ‘time’ can begin with an interesting observation. The Lorentz transformation equations show that measurements along the axis of motion (the x-axis) are a function of ‘t’ (read as ‘time’) and that transforming time (‘t’) readings from one system to another involves distance (‘x’) measurements. Out of this fact comes a rather startling distinction between distance ‘s’ in Newtonian physics (Euclidean) and in Einsteinian physics (non-Euclidean).
