fundamental mathematics (I mean very very basic)[

the definition of a rational number: any number that could be express in n/m, such that n,m is an arbitrary natural number. the fact that there is no two numbers n,m in N, such that n/m=pi makes pi irrational, wether you like it or not. In fact pi is a trancendental number, a number which is not the root of any polynomial equation with integer coefficients.
