Una moderna presentazione della teoria della Relativit� Ristretta, specificatamente progettata according to i nuovi corsi della Laurea Triennale in Fisica. Un testo essenziale ma autosufficiente, che adotta lo stile e il linguaggio delle lezioni svolte in aula, e che introduce alle trasformazioni di Lorentz, alla formulazione covariante dell'elettromagnetismo e alle basi della cinematica e dinamica relativistiche.
