Relativistic reflection of light, Break of Lorentz symmetry, Principle of Least Action, Principle of the Least Area, Violation of the Principle of Least Area
It is proved in this chapter a significant break of symmetry in the reflection of light by an inclined mirror when observed in relative motion: the reflection is always symmetrical in the proper reference frame of the mirror and the source of light, but it is not symmetrical in other different inertial reference frames. The Law of Least Area is also introduced in the last section of this chapter. Somehow related to the Principle of Least Action, the Law of Least Area also has significant consequences on the First Principle of Relativity as formulated in special relativity.
