Can you fold a piece of paper in half? Of course you can, it’s easy, you just match the two corners along one side. But can you fold it in thirds? You might be able to fold it into thirds with a bit of fiddling and guessing, but what about into fifths? Or sevenths? Or thirteenths? Here is a simple way you can fold a piece of paper into any fraction you would like – exactly – no guessing or fiddling needed!

<p>How to solve an ancient problem in a few folds.</p>
</div>
</div>
</div>
<p>Over 2000 years ago the Greek mathematician <a href="http://www-history.mcs.st-and.ac.uk/Biographies/Euclid.html">Euclid of Alexandria</a> laid down the foundations of geometry. But Euclid's geometry was very different from ours. It was all about the geometric shapes you could produce using just a straightedge (a ruler without markings) and a compass. You can do lots of useful things with these tools. For example, you can such divide an angle into two equal halves:.</p><p><a href="https://plus.maths.org/content/trisecting-angle-origami" target="_blank">read more</a></p>https://plus.maths.org/content/trisecting-angle-origami#commentsangle trisectioncreativitygeometryorigamiFri, 31 Oct 2014 10:42:11 +0000mf3446228 at https://plus.maths.org/contentTic-tac-toe!
https://plus.maths.org/content/tic-tac-toe
<p>We have just learnt a really nice fact about the game of tic-tac-toe. As you may know, tic-tac-toe always results in a draw if both players make the best moves possible at every step of the game. To force a draw you need to follow a particular strategy, which isn't too hard, but tedious to write down (see <a href="http://en.wikipedia.org/wiki/Tic-tac-toe#Strategy">here</a>).</p>

<p>Why game theory is a serious business.</p>
</div>
</div>
</div>
<p>The easy answer is "for fun", just like the rest of us. It's obvious
that being good at maths can help you in many difficult games, such as
chess. But there is another reason too. Mathematicians are interested
in games because they can help us understand why we humans (and other
animals) behave as we do. A whole area of mathematics, called <em>game
theory</em>, has been developed to cast some light on our
behaviour, especially the way we make decisions.</p><p><a href="https://plus.maths.org/content/why-do-mathematicians-play-games" target="_blank">read more</a></p>https://plus.maths.org/content/why-do-mathematicians-play-games#commentscreativitygame theoryTue, 23 Sep 2014 11:04:31 +0000mf3446186 at https://plus.maths.org/contentBe creative!
https://plus.maths.org/content/be-creative
<p>
"Ingenuity", "far reaching vision", "unerring sense", "deep
curiosity" — and best of all,
"extraordinary creativity". These are some of the words that have been
used to praise this year's Fields medallists at the <a href="https://plus.maths.org/content/icm-2014">International
Congress of Mathematicians</a> (ICM). These words aren't specific to maths. They
could be used to describe anyone whose work is about discovery and
beauty; writers, poets, or musicians for example. If there has
been one overarching theme at this ICM, it's just how creative a
subject mathematics is.<p><a href="https://plus.maths.org/content/be-creative" target="_blank">read more</a></p>https://plus.maths.org/content/be-creative#commentscreativityICM 2014Wed, 20 Aug 2014 04:18:26 +0000mf3446170 at https://plus.maths.org/contentPlay to win with Nim

<p>In the game of Nim one player always has a winning strategy — it depends on an unusual way of adding numbers.</p>
</div>
</div>
</div>
<p>Some games are all about luck. Your winning chance depends on the
roll of a die or the cards you've been dealt. But there are
other games that are only about strategy: if you play cleverly, you're
guaranteed to win. </p>
<p>A great example of this is the ancient gam of Nim. Whatever the
state of the game, there is a winning strategy for one of the two
players. And a very cute form of addition tells you which of the two

<p>Asking good questions is an important part of doing maths. But what makes a good question?</p>
</div>
</div>
</div>
<p>What makes a good maths question? If you are a student facing exams,
you might (understandably) say that good means easy. But if
you're doing maths for fun, or are a professional mathematician, your
answer is going to be different. An easy question is boring, but you
also wouldn't want to gnaw your teeth out at something that is
completely inaccessible. What
mathematicians like most are questions that lead to new insights, to
new ways of looking at things, or pose a completely new type of
problem. Asking "good" questions is an important part of doing
maths.<p><a href="https://plus.maths.org/content/power-good-question" target="_blank">read more</a></p>https://plus.maths.org/content/power-good-question#commentsart gallery problemcalculuscreativityFermat's Last Theoremfour-colour theoremgraph theoryTue, 24 Jun 2014 09:03:15 +0000mf3446114 at https://plus.maths.org/contentThe art gallery problem

<p>Patterns and structures lie at the heart of mathematics, some even say they are mathematics. But how do they help us do mathematics?</p>
</div>
</div>
</div>
<p>
"A mathematician, like a painter or a poet, is a maker of patterns. If his patterns are more permanent than theirs, it is because they are made with ideas." This much quoted line is from British mathematician G. H. Hardy's famous book, <em>A mathematician's apology</em>, written in 1940. And any mathematician, from the ancient Greeks to those working today, would agree.

Where were your most creative experiences at school? In art class? In music? English? In your maths lesson? That last one might not be the obvious choice for many of us, unless you were lucky enough to have a really inspiring maths teacher. But that is exactly the type of opportunity we are hoping to create for maths students aged 7-16 as part of the project, <em>Developing Mathematical Creativity</em>, with our sister site, <a href="http://nrich.maths.org">NRICH</a>.

Can we always find order in systems that are disordered? If so, just how
large does a system have to be to contain a certain amount of order?

Let's consider a concrete example. Suppose there is a
room with six people in it. We are interested in whether
people in this room know each other or not. Let's call two
people friends if they know each other, strangers if they
don't.
