### Numberphile Breaks Down the Twin Prime Theory in (Mostly) Plain English [Video]

#### Wondering why Yitang Zhang's work on prime numbers is such a big deal? Because 70,000,000 is closer to 2 than you might think...

Earlier this month, we brought you the news that **University of New Hampshire mathematician Yitang Zhang proved a weak version of the twin prime conjecture**, showing that there is an endless supply of prime pairs which are separated by no more than 70,000,000. That seems like it's a long way from proving the proper twin prime conjecture -- showing an infinite number of primes separated by just two digits -- but it might not be. **In their latest video, the math whizzes at Numberphile offer a great layman's explanation of what the twin prime conjecture is and what Zhang's work means for it. **
