## That figures: Professor who had to work at Subway dazzles world of maths after solving centuries-old prime number riddle

(Phys.org) —Mathematician Yitang Zhang of the University of New Hampshire, appears to have taken a major step in solving the twin prime conjecture. He's come up with a mathematical proof that shows that the number of pairs of prime numbers that exist that are less than 70 million units apart is infinite. His proof is currently under review for publication in the journal Annals of Mathematics.
