Riemann created a new type of geometry that became useful in the next century, and he formulated the most famous hypothesis (the [[Riemann hypothesis]]) that remains unsolved in mathematics today.  It concerns the distribution of prime numbers and was first proposed in Riemann's class paper ''On the Number of Primes Less Than a Given Magnitude'' (1859).<ref>http://www.andrews.edu/~calkins/math/biograph/199899/bioriema.htm</ref>
