## What is the the twin prime conjecture?

## What is the the twin prime conjecture?

The twin primes conjecture concerns pairs of prime numbers with a difference of 2. The numbers 5 and 7 are twin primes. So are 17 and 19. The conjecture predicts that there are infinitely many such pairs among the counting numbers, or integers.

### Is the twin prime conjecture true?

In a paper published Aug. 12 in the preprint journal arXiv, as Quanta first reported, two mathematicians proved that the twin prime conjecture is true — at least in a sort of alternative universe. This is what mathematicians do: work toward big proofs by proving smaller ideas along the way.

**How many twin prime conjecture are there?**

There are two related conjectures, each called the twin prime conjecture. The first version states that there are an infinite number of pairs of twin primes (Guy 1994, p. 19).

**Is twin prime conjecture solved?**

The ‘twin prime conjecture’ holds that there is an infinite number of such twin pairs. Some attribute the conjecture to the Greek mathematician Euclid of Alexandria; if true that would make it one of the oldest open problems in mathematics. So far, the problem has eluded all attempts to find a solution.

## What pair of 137 is called twin primes?

The first few twin prime pairs are: (3, 5), (5, 7), (11, 13), (17, 19), (29, 31), (41, 43), (59, 61), (71, 73), (101, 103), (107, 109), (137, 139), …

### Why is Goldbach’s conjecture unsolved?

There is no solid reason for suggesting that Goldbach’s conjecture cannot be proved on the basis of the usual axioms of mathematics; the only justification for such a claim is that the problem has been around for almost 280 years. But let us suppose the conjecture is unprovable.

**Can the twin prime conjecture be solved?**

**What is the highest twin prime?**

Large twin primes As of September 2018, the current largest twin prime pair known is 2996863034895 · 21290000 ± 1, with 388,342 decimal digits.

## Do twin primes go on forever?

But there are exceptions: the ‘twin primes’, which are pairs of prime numbers that differ in value by just 2. Examples of known twin primes are 3 and 5, 17 and 19, and 2,003,663,613 × 2195,000 − 1 and 2,003,663,613 × 2195,000 + 1. The ‘twin prime conjecture’ holds that there is an infinite number of such twin pairs.

### Are 107 and 109 twin primes?

**Are twin primes infinite?**

**What is the twin prime conjecture?**

The twin prime conjecture is the case when k = 2. It is towards this conjecture that Yitang Zhang made his remarkable contribution. Zhang showed that this conjecture is true for some k < 70 million. It is the first time that such a claim has been proved.

## What did Yitang Zhang just prove about prime numbers?

But what Yitang Zhang just proved is that there are infinitely many pairs of primes that differ by at most 70,000,000. In other words, that the gap between one prime and the next is bounded by 70,000,000 infinitely often—thus, the “bounded gaps” conjecture.

### What did Yitang Zhang just prove about bounded gaps?

But what Yitang Zhang just proved is that there are infinitely many pairs of primes that differ by at most 70,000,000. In other words, that the gap between one prime and the next is bounded by 70,000,000 infinitely often—thus, the “bounded gaps” conjecture. On first glance, this might seem a miraculous phenomenon.

**Who is Yitang Zhang?**

The 2014 MacArthur “Genius” Fellows class has been announced, and among the 21 thinkers is mathematician Yitang Zhang. In spring 2013, Zhang made an amazing breakthrough in a classic problem that has eluded mathematicians for centuries.
