"...possible breakthrough in a very old, very sticky problem in number theory. #RiemannsHypothesis —concerning the distribution of prime numbers throughout the number line — dates back over 160 years. While the new paper doesn’t purport to solve the problem, it could be a substantial step toward a solution. That could enable other number theorists to keep taking steps toward solving it, and (perhaps more importantly) winning a $1 million prize." https://www.popularmechanics.com/science/math/a61491065/mathematicians-close-to-solving-notorious-math-problem-riemann-hypothesis/ The seven #MillenniumProblems: https://www.claymath.org/millennium-problems/
