Maths fact!

Right everyone I know that we haven't had a fact in a while so...........

The sum of the reciprocals of all prime numbers diverges:
\sum_{p}\frac1p = \frac12 + \frac13 + \frac15 + \frac17 + \frac1{11} + \frac1{13} + \cdots = \infty
This was proved by Leonhard Euler in 1737!

This also links to the another fact that there is an infinite number of primes (two facts for the price of one!) which was proved by Euclid (300 B.C) way before Euler was even a twinkle in his mothers eye.
