On the Arbitrary Choice Regarding which Inertial Reference Frame is   "Stationary" and which is "Moving" in the Special Theory of Relativity
  Einstein's argument on the relativity of simultaneity itself is the first result of the special theory of relativity. The nature of this result is explored, and implications of this result for the structure and functioning of the physical world found in the special theory are discussed.
