    "abstract": "The Lorentz Transformation is derived from only three simple postulates:\n  (i) a weak kinematical form of the Special Relativity Principle that requires\nthe equivalence of reciprocal space-time measurements by two different inertial\nobservers;\n  (ii) Uniqueness, that is the condition that the Lorentz Transformation should\nbe a single valued function of its arguments;\n  (iii) Spatial Isotropy.\n  It is also shown that to derive the Lorentz Transformation for space-time\npoints lying along a common axis, parallel to the relative velocity direction,\nof two inertial frames, postulates (i) and (ii) are sufficient. The kinematics\nof the Lorentz Transformation is then developed to demonstrate that, for\nconsistency with Classical Electrodynamics, light must consist of massless (or\nalmost massless) particles: photons.",
