Special Theory of Relativity without special assumptions and tachyonic motion
(The Alfred Meissner Graduate School for Dental Engineering and Humanities, Ustroń, ul. Sioneczna 2, Poland)
The most general form of transformations of space-time coordinates in Special Theory of Relativity based solely on physical assumptions is described. Only the linearity of space-time transformations and the constancy of the speed of light are used as assumptions. The application to tachyonic motion is indicated.
Minkowski space-time, Lorentz transformations, tachyons, Maxwell equations
