The concept of p-adic number was first introduced by Hensel in 1897, but it can be found in some previous works of Kummer. The main motivation for their introduction was the use of some techniques of mathematical analysis in number theory. For example, they play a keyrole in proving Fermat's Last Theorem. The p-adic numbers have important applications in physics (quantum physics, string theory), but in the recent years they have been used in other domains such: computer sciences, cognitive sciences, psychology, sociology, biology and genetics. In this paper we explain the notion of p-adic number and we briefly present some applications with references.
