# AI Closes In On Math's Biggest Target | World Science Festival

AI just took an unprecedented step toward solving what is arguably math’s most towering problem: to prove the Riemann Hypothesis, which holds the key to the distribution of prime numbers. Alex Kontorovich, professor of mathematics at Rutgers University, joins Brian Greene to explain the result, and what it means for a field that has worked on these questions for more than a century.

Kontorovich lays out the connection between prime numbers and the Riemann zeta function, then explains what the new proof establishes and what it leaves open. He and Brian turn to the harder question of what mathematics becomes when machines can produce theorems that humans pursued for lifetimes. Kontorovich, argues that the value of a mathematician is shifting toward understanding and communication, and lays out why he remains optimistic about where mathematics is headed.

This program is part of the Rethinking Reality series, supported by the John Templeton Foundation.

ABOUT WORLD SCIENCE FESTIVAL: The World Science Festival (WSF) is a multimedia organization bringing the most transformative ideas in science to global audiences. Through long- and short-form videos spanning physics, cosmology, quantum mechanics, biology, neuroscience, consciousness, medicine, space exploration, the dilemma of free will, artificial intelligence, engineering, robotics, and beyond. WSF gathers world-renowned scientists, artists, and thinkers for dynamic discussions, debates, lectures, performances, films, and immersive live experiences.

Founded in 2008 and headquartered in New York City, the World Science Festival is a production of the World Science Foundation, a 501(c)(3) nonprofit organization. Our mission is to cultivate a public informed by science, inspired by its wonder, convinced of its value, and prepared to engage with its implications for the future. With live events reaching millions worldwide and hundreds of millions of digital views, WSF continues to expand its global impact through…
