The article tells the story of Yitang Zhang, a Chinese-American mathematician who made an important breakthrough in number theory in 2013.
At the time, Zhang was 58 years old and worked as a lecturer at the University of New Hampshire. He had not published original research for more than a decade and had previously worked several jobs, including managing the finances of a friend’s Subway restaurant. Despite being relatively unknown in the mathematical community, he continued working independently on a very difficult problem: the twin prime conjecture.
The twin prime conjecture asks whether there are infinitely many pairs of prime numbers that differ by exactly two, such as 11 and 13 or 17 and 19. The conjecture had remained unsolved for centuries.
Zhang did not solve the twin prime conjecture itself. Instead, his 2013 paper, “Bounded Gaps Between Primes,” proved that there is some fixed number smaller than 70 million such that infinitely many pairs of prime numbers differ by that amount. This was a major breakthrough because, before Zhang’s work, mathematicians had not been able to prove that any finite bound existed.
His paper was submitted to the Annals of Mathematics on April 17, 2013, and was accepted only a few weeks later, which was extremely fast for such a prestigious mathematical journal. His result attracted considerable attention from mathematicians around the world.
The article’s main message is that important scientific discoveries do not always come from famous researchers or prestigious institutions. Zhang’s story highlights the importance of persistence, independent thinking, and continuing to work on difficult problems even when nobody is paying attention.
