http://plus.maths.org/content/bridges-konigsberg-movie
<p>We've read the book. We've bought the T-shirt. And now, finally, here it is: the movie of one of our favourite maths problems, the bridges of Königsberg. Though admittedly, we made it ourselves. We learnt several interesting lessons in the process. For example that a bin doesn't make a good supporting character and that people who shouldn't be in the frame should get out of it. But other than that, we're well on course for an Oscar this weekend!</p><p><a href="http://plus.maths.org/content/bridges-konigsberg-movie" target="_blank">read more</a></p>http://plus.maths.org/content/bridges-konigsberg-movie#commentsBridges of Konigsberggraph theoryThu, 27 Feb 2014 13:00:27 +0000mf3446053 at http://plus.maths.org/contentMaths in a minute: The bridges of Königsberg

cities Königsberg was divided by a river, called the Pregel. It contained two
islands and there were seven bridges linking the various land masses. A
famous
puzzle at the time was to find a walk through
the city that crossed every bridge exactly once. Many people claimed
they had found such a walk but when asked to reproduce it no one was able to.<p><a href="http://plus.maths.org/content/maths-minute-bridges-konigsberg" target="_blank">read more</a></p>http://plus.maths.org/content/maths-minute-bridges-konigsberg#commentsBridges of Konigsbergcreativitygraph theorytopologyWed, 20 Nov 2013 09:05:11 +0000mf3445969 at http://plus.maths.org/contentHappy birthday, London Underground!

<p>The London Underground turns 150 today! It's probably the most famous rail network in the world and much of that fame is due to the iconic London Underground map. But what makes this map so special?</p>

<p><b>C. J. Budd</b> and <b>C. J. Sangwin</b> show us how to create mazes, and explain why mazes and networks have much in common. In fact the study of mazes and labyrinths takes us into the dark territory of murder, suicide, adultery, passion, intrigue, religion and conquest...</p>
