This book is dedicated to Einstein's special relativity. The main topics are: postulates of relativity, events and Minkowski space-time, Lorentz transformations, metrics in scalar products (with an analysis on the metric tensor in an Euclidean and Minkowski space), intervals and their classification, effects of relativity such as time dilation and length contraction, speed transformations, equation of motion in relativistic dynamics, relativistic Lagrangian, kinetic, mass and total energy and their non-relativistic limits, four-momentum conservation.
