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.
