A new proof has brought mathematicians one step closer to understanding the hidden order of those “atoms of arithmetic,” the prime numbers.
The primes—numbers that are only divisible by themselves and 1—are the most fundamental building blocks in math. They’re also the most mysterious. At first glance, they seem to be scattered at random across the number line. But of course, the primes aren’t random. They’re completely determined, and a closer look at them reveals all sorts of strange patterns, which mathematicians have spent centuries trying to unravel. A better understanding of how the primes are distributed would illuminate vast swaths
