This will be a book on the foundations of Special Relativity from a synthetic viewpoint. This means that we start from a few postulates on how to represent light rays and the principle of inertia and using Einstein's idea of light clocks we define the notion of measure of time and distance (and simultaneity) and introduce coordinates a posteriori.
The book has a strong visual appeal, modelling with affine geometry. As a subproduct we develop several geometric algorithms which allow us to write programs to visualize relativistic motions.
