One of my favorites is Brun's theorem that shows that the sum of reciprocals of the twin primes converges to a value now known as Brun's constant: http://oeis.org/A065421 Victor PS. To my mind the greatest thing that Alan Adler did was to invent the Aeropress. If you don't know about it, it's an incredible way of making great coffee.

finds Euler's product over primes for zeta(s) somewhat magical, and wonders if we funsters know other really neat sums or products involving primes. Hence yesterday's "Minor twist". Otherwise, all I could remember was our Valentine's Day 2011 discussion of "Euler's crazy pi product". --rwg
