<p>Agreeing to pay £50,000 for something worth £2 wouldn't win you any haggling competitions. In mathematics, however, a similar result can bring you international acclaim. Mathematics can be a lot like haggling: if you can't get the answer you want, you try to get as close as possible. In the case of the famous <em>twin prime conjecture</em> the answer you want is 2. Recent results claim to have managed just over 50,000, but they are causing quite a stir.
That's because the gap between 2 and 50,000 is a whole lot smaller than the gap between 50,000 and infinity. </p><p><a href="https://plus.maths.org/content/twins-move-within-reach" target="_blank">read more</a></p>https://plus.maths.org/content/twins-move-within-reach#commentsnumber theorytwin prime conjecturetwin primesTue, 25 Jun 2013 09:56:49 +0000mf3445914 at https://plus.maths.org/contentMathematical mysteries: twin primes

<p>Prime numbers are a rich and ancient source of mathematical mystery. It has been known for over 2000 years that there are an infinite number of them.</p>
<p>This issue's mathematical mystery concerns pairs of prime numbers called <em>twin primes</em>. A pair of prime numbers are twins if they differ by 2. If you look at a list of the first 50 primes you'll see that it contains 16 twin prime pairs:</p><p><a href="https://plus.maths.org/content/mathematical-mysteries-twin-primes" target="_blank">read more</a></p>https://plus.maths.org/content/mathematical-mysteries-twin-primes#comments4Mathematical mysteriesprime numbertwin primesThu, 01 Jan 1998 00:00:00 +0000plusadmin4761 at https://plus.maths.org/content
