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). | 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.
