Il piccolo Einstein nasce a Ulm, in Germania. Non sopporta la disciplina e, al ginnasio, ha vita dura. Soggiorna in Italia, poi s'iscrive al Politecnico a Zurigo, s'innamora e studia fisica. Dopo la laurea fa l'impiegato (tiene famiglia ormai) e tra una pratica e l'altra scrive articoli scientifici. A 26 anni pubblica l'articolo sulla teoria della relatività. Fa il professore in Germania, fugge al nazismo e va in America. Continua a studiare, pubblicare e insegnare: è ormai famoso e lotta per la pace. Termina il suo tempo relativo nel 1955. E la macchina del tempo?
