Re: Sum of 1/Primes


The fact that  Sum[1/Prime[n], {n, 1,Infinity}]==Infinity is a rather 
famous theorem of  Euler. It implies that there must be infinitely many 
primes (otherwise the sum would be finite), and was the beginning of a 
vast area of mathematics, which includes such concepts as Dirichlet 
series, Riemann's zeta function etc.
