Complex colouring
http://plus.maths.org/content/complexcolouring
<p>No, honestly, this isn't abstract art! At least not on purpose. It's a visualisation of a function of a <a href="http://plus.maths.org/content/teacherpackagecomplexnumbers">complex variable</a> using a method called <em>domain colouring</em>.</p>

Tictactoe!
http://plus.maths.org/content/tictactoe
<p>We have just learnt a really nice fact about the game of tictactoe. As you may know, tictactoe 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/Tictactoe#Strategy">here</a>).</p>

Order in disorder
http://plus.maths.org/content/orderdisorder
<p>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? In this video <a href="https://www.dpmms.cam.ac.uk/~leader/">Imre Leader</a> of the Department of Pure Mathematics and Mathematical Statistics at the University of Cambridge gives an equation free introduction to a fascinating area of maths called <em>Ramsey theory</em>.

You might be surprised at what our image of the week depicts – commuting times! It shows the areas accessible by public transport from Cambridge, leaving at 9.00am on a weekday morning. The coloured circles depict the travel time in bands of 10 minutes. Thank you to those kind souls travelling for over an hour for giving us so many beautiful colours!<p><a href="http://plus.maths.org/content/beautifulcommute" target="_blank">read more</a></p>
