Elementary theory of relativity

An easy comprehensible, new approach is developed for deriving Einstein's Special Theory of Relativity. In this context, the universal constancy of the speed of light, Einstein's special principle of relativity will be explained. Furthermore, the complete framework of special relativity - including the paradoxa and philosophical topics, tachyons and causality and even the limits of validity - can be understood with the help of a surprising physical model.
