Radical Relativity: An Uncommon Way to Spacetime

Special relativity is at the foundation of any physical theory. Though, its consequences leave us with unexpected results in kinematics, dynamics and, to a lesser extent, in electrodynamics.

We introduce the theory of relativity including geometry and chronology, from the view of a local observer who encounters aberration and Doppler shift. The description of motion in Minkowski spacetime requires a careful distinction between different operational concepts of measuring time and space inte...
