<p><em>Plus</em> has teamed up with the Royal Society Summer Science
Exhibition 2011 to reveal the maths behind some of the science on show. We have chosen two exhibits from this year's participants and produced
postcards for people to pick up at the stand, accopmanied by <em>Plus</em> articles to reveal some of the the maths behind
them. Read the articles and if you
can't make it to the exhibition yourself, you can also download pdfs
of the postcards. </div>

<p>How would it feel to look in a mirror and see not your own reflection but instead how you would look as the opposite sex? You can explore this strange alternate reality at this year's Royal Society Summer Exhibition where scientists from Queen Mary, University of London and University College London will use mathematical wizardry to produce gender reversed images of faces.</p>

<p>Airport security staff have a daunting task. With impatient queues looming over them they need to search x-ray scans of cluttered suitcases for several items at once: knives, guns and bombs. How can we ease their task and make sure they don't miss a crucial item? To find out, scientists are trying to understand how we humans take in visual information. The humble triangle plays a crucial role in the experiments they perform.</p>

<p>Foraging ants have a hard life, embarking on long and arduous trips several times a day, until they drop dead from exhaustion. The trips are not just long, they also follow complex zig-zag paths. So how do ants manage to find their way back home? And how do they manage to do so along a straight line? Their secret lies in a little geometry.</p>
</div>

<p>The life of a foraging ant is tedious and boring. It involves nothing more than repeated trips between food sources and the nest. These trips are arduous and long. A single foraging trip of an ant, one of many in a day, might be hundreds of metres. We can put this in human terms by comparing this foraging distance to the body-length of an ant. A 200m journey for an ant represents a distance of over 26,000 body lengths. For a human of average height that would equate to a trip of 30 miles. An ant forager will repeat this journey until she drops dead from exhaustion.</p><p><a href="http://plus.maths.org/content/finding-way-home" target="_blank">read more</a></p>http://plus.maths.org/content/finding-way-home#commentsmathematical realityevolutionmaths insidenavigationvectorThu, 14 Apr 2011 11:39:20 +0000mf3445460 at http://plus.maths.org/contentHow do insects find their way home?
