The Riemann hypothesis is widely considered the outstanding unsolved problem in mathematics. Generations of mathematicians have been lured into hunting for a proof of this celebrated conundrum. All have so far failed.
In the late 1990s, however, a cautious optimism took hold among mathematicians tangling with the problem.

"It is a curious fact about the human mind that people will work harder to do something which captures their imagination than they will for any practical purpose," mathematician J. Ian Richards once commented.
