On May 13, an obscure mathematician one whose talents had gone so unrecognized that he had worked at a Subway restaurant to make ends meet garnered worldwide attention and accolades from the mathematics community for settling a long-standing open question about prime numbers, those numbers divisible by only one and themselves. Yitang Zhang, a lecturer at the University of New Hampshire, showed that even though primes get increasingly rare as you go further out along the number line, you will never stop finding pairs of primes separated by at most 70 million. His finding was the first time anyone had managed to put a finite bound on the gaps between prime numbers, representing a major leap toward proving the centuries-old twin primes conjecture, which posits that there are infinitely many pairs of primes separated by only two (such as 11 and 13).
In the months that followed, Zhang found himself caught up in a whirlwind of activity and excitement: He has lectured on his work at many of the nations preeminent universities, has received offers of jobs from top institutions in China and Taiwan and a visiting position at the Institute for Advanced Study in Princeton, N.J., and has been told that he will be promoted to full professor at the University of New Hampshire.
Meanwhile, Zhangs work raised a question: Why 70 million? There is nothing magical about that number it served Zhangs purposes and simplified his proof. Other mathematicians quickly realized that it should be possible to push this separation bound quite a bit lower, although not all the way down to two.
By the end of May, mathematicians had uncovered simple tweaks to Zhangs argument that brought the bound below 60 million. A May 30 blog post by Scott Morrison of the Australian National University in Canberra ignited a firestorm of activity, as mathematicians vied to improve on this number, setting one record after another. By June 4, Terence Tao of the University of California, Los Angeles, a winner of the Fields Medal, mathematics highest honor, had created a Polymath project, an open, online collaboration to improve the bound that attracted dozens of participants.

(1,582 posts)After graduating, Einstein spent almost two frustrating years searching for a teaching post. With the help of Marcel Grossmann's father Einstein secured a job in Bern at the Federal Office for Intellectual Property, the patent office, as an assistant examiner.
After graduation, Zhang had a hard time finding an academic position. In a recent article, Zhang's thesis advisor, Professor Tzuong-Tsieng Moh, recalled that "Sometimes I regretted not fixing him a job" and "He never came back to me requesting recommendation letters." He managed to find a position as a lecturer after many years. He is still currently a lecturer at the University of New Hampshire, where he was hired by Kenneth Appel back in 1999. Prior to getting back to academia, he worked for several years as an accountant and a delivery worker for a New York City restaurant. He also worked in a motel in Kentucky and in a Subway sandwich shop.
