The basic ideas to separate fundamental physical principles from any particular geometry of space and time can be traced back to the Austrian physicist Fridrich Kottler and were taken up by the Dutch school of geometers. It has been noticed that the concept of metric and measurements of lengths, angles and time intervals is perhaps the most sophisticated aspect of any field theory. In fact, the fundamental balance equations governing electrodynamics are not related to notions like inertial frames, rigid rods, absolute or uniform time, Lorentz- or Galilean transformations, etc., an hence deserve an independent mathematical expression. In a certain sense, they have tpological significance, transcending both the intuition and the mathematics of length and time.
