<p>There's been progress on one of the biggest open problems in maths: the twin prime conjecture.</p>
</div>
</div>
</div>
<p>When <a href="http://www.magd.ox.ac.uk/member-of-staff/james-maynard/">James Maynard</a> gave his talk at the <a href="http://www.bmc-bamc.org.uk">British (Applied)
Mathematics Colloquium</a> last week, there was a distinct air of
expectation in the room — and no seats left as so many mathematicians
had squeezed in to see him. The reason was two-fold: not only
has Maynard made significant progress in one of the biggest open
problems in maths, but also is
this problem really easy to understand, even if
you are not a mathematician.<p><a href="https://plus.maths.org/content/find-gap" target="_blank">read more</a></p>https://plus.maths.org/content/find-gap#commentsBMC2015Goldbach Conjecturenumber theoryprime numbertwin prime conjectureThu, 09 Apr 2015 13:24:26 +0000mf3446346 at https://plus.maths.org/contentMaths in a minute: Number mysteries

<p>Number theory is famous for problems that everyone can understand and that are easy to express, but that are fiendishly difficult to prove. Here are some of our favourites.</p>
<h3>The Goldbach conjecture</h3>
<p>The Goldbach conjecture is named after the mathematician <a href="http://www-history.mcs.st-and.ac.uk/Biographies/Goldbach.html">Christian Goldbach</a> who formulated it in the middle of the eighteenth century. It states that any even natural number greater than 2 can be written as the sum of two prime numbers. </p><p><a href="https://plus.maths.org/content/maths-minute-number-mysteries" target="_blank">read more</a></p>https://plus.maths.org/content/maths-minute-number-mysteries#commentsGoldbach ConjectureMersenne primeMersenne searchnumber theoryperfect numberprime numberTue, 16 Jul 2013 08:49:15 +0000mf3445925 at https://plus.maths.org/contentGold for Goldbach

<p>In 1998, Goldbach's Conjecture was shown by computer to be true for even numbers up to 400,000,000,000,000. In addition, some progress has been made towards formally proving the conjecture. As of this year, mathematicians with Goldbach fever have some extra incentive for their labours.</p>

<p>Leonard Euler (1707-1783) corresponded with Christian Goldbach about the conjecture now named after the latter. </p>

<p>Here is one of the trickiest unanswered questions in mathematics:</p>
<p><em>Can every even whole number greater than 2 be written as the sum of two primes?</em></p>
<p>A prime is a whole number which is only divisible by 1 and itself. Let's try with a few examples:</p><p><a href="https://plus.maths.org/content/mathematical-mysteries-goldbach-conjecture" target="_blank">read more</a></p>https://plus.maths.org/content/mathematical-mysteries-goldbach-conjecture#comments2Goldbach calculatorGoldbach ConjectureMathematical mysteriesprime numberWed, 30 Apr 1997 23:00:00 +0000plusadmin4756 at https://plus.maths.org/content
