Einstein: annus mirabilis

Abstract

In March 1905, when Albert Einstein was celebrating his 26th birthday, a series of his papers was fi rst published turning over a new leaf in Physics, knowledge and culture until nowadays. It was his annus mirabilis, a period in which, among papers and declarations to patent electric products in a Swiss company, his imagination gave rise to a concept both materialistic and transcendent: the time-space dimension or time as the fourth dimension. This paper intends to show the conditions that surrounded Einstein in 1905 concerning his intellectual and familiar development during the creation of his articles.
