If you don’t know the guy on the other side of the world, love him anyway because he’s just like you. He has the same dreams, the same hopes and fears. It’s one world, pal. We’re all neighbors.

- Riemann hypothesis (Wikipedia)
In mathematics, the Riemann hypothesis is the conjecture that the Riemann zeta function has its zeros only at the negative even integers and complex numbers with real part 1/2. Many consider it to be the most important unsolved problem in pure mathematics. It is of great interest in number theory because it implies results about the distribution of prime numbers. It was proposed by Bernhard Riemann (1859), after whom it is named.
