A Note on Interpreting Special Relativity

Authors: A J Owen

In this note I have discussed Einstein's theory of special relativity, derived the coordinate transformations in a simple manner, and obtained expressions for time dilation, the relativistic Doppler effect and length contraction. In Einstein's original paper, a factor \phi appears, which he sets equal to unity. However, \phi can be reinterpreted as a scale factor when coordinate time is defined via a single coordinate clock and the time delay receiving information via light rays is included. Using Einstein's definition of coordinate time, a moving sphere is construed as an ellipsoid of revolution, whereas the practical definition of time intervals used here - implying simultaneity of reception rather than simultaneity of occurrence - shows it is a rotated sphere.
