    "abstract": "Special relativity is reformulated as a symmetry property of space-time:\nSpace-Time Exchange Invariance. The additional hypothesis of spatial\nhomogeneity is then sufficient to derive the Lorentz transformation without\nreference to the traditional form of the Principle of Special Relativity. The\nkinematical version of the latter is shown to be a consequence of the Lorentz\ntransformation. As a dynamical application, the laws of electrodynamics and\nmagnetodynamics are derived from those of electrostatics and magnetostatics\nrespectively. The 4-vector nature of the electromagnetic potential plays a\ncrucial role in the last two derivations.",
