<p>Remember how hard it was to fold maps? Mathematicians have struggled with map folding problems for ages but a recent insight suggests there might be another way to approach them, making an unlikely connection between combinatorics, origami and engineering.</p>

<p>Suppose you have an infinitely large sheet of paper (mathematicians refer to this hypothetical object as the plane). You also have a number of different colours - pots of paint, perhaps. Your aim is to colour every point on the plane using the colours available. That is, each point must be assigned one colour.</p>

<p>Suppose you have an infinitely large sheet of paper (mathematicians refer to this hypothetical object as the <i>plane</i>). You also have a number of different colours - pots of paint, perhaps. Your aim is to colour every point on the plane using the colours available. That is, each point must be assigned one colour.</p>
<p>Can you do this so that, for any two points on the plane which are exactly 1cm apart, they are given different colours?</p><p><a href="https://plus.maths.org/content/mathematical-mysteries-painting-plane" target="_blank">read more</a></p>https://plus.maths.org/content/mathematical-mysteries-painting-plane#comments15Mathematical mysteriesplane colouringRamsey theoryMon, 30 Apr 2001 23:00:00 +0000plusadmin4750 at https://plus.maths.org/content
