## twin prime conjecture

1. ### 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.

2. ### Kind of a Big Deal: Mathematician Proves Weak Version of Twin Prime Conjecture

The twin prime conjecture states that there are an infinite number of twin primes -- prime numbers where one prime is two greater than the other. For example, 1 and 3 are twin primes, so are 101 and 103, 881 and 883, and so on. This conjecture has never been proven, but Yitang Zhang believes he has proven there are infinite primes paired with other primes no greater than 70 million more than themselves. Here's why that's kind of a big deal.
