If you've ever watched a flock of birds flying at dusk, or a school of fish reacting to a predator, you'll have been amazed by their perfectly choreographed moves. Yet, complex as this behaviour may seem, it's not all that hard to model it on a computer. <b>Lewis Dartnell</b> presents a hands-on guide for creating your own simulations — no previous experience necessary. </div>

<p>Building models forms the core of many areas of scientific and engineering research. Essentially, a model is a representation of a complex system that has been simplified in different ways to help understand its behaviour. An aeronautical engineer, for example, might build a miniaturised physical model of a fighter plane to test in a wind tunnel. In modern times, more and more modelling is
being performed by computers — running mathematical models at very high rates of calculations.<p><a href="https://plus.maths.org/content/matrix-simulating-world-part-i-particle-models" target="_blank">read more</a></p>https://plus.maths.org/content/matrix-simulating-world-part-i-particle-models#comments42computer animationcomputer programmingcomputer sciencecomputer simulationemergent behaviourmathematical modellingThu, 01 Mar 2007 00:00:00 +0000plusadmin2302 at https://plus.maths.org/contentHow time does PASS

<p>Leonhard Euler was the most prolific mathematician of all time. He wrote more than 500 books and papers during his lifetime — about 800 pages per year — with an incredible 400 further publications appearing posthumously. His collected works and correspondence are still not completely published: they already fill over seventy large volumes, comprising tens of thousands of pages.</p><p><a href="https://plus.maths.org/content/os/issue42/features/wilson/index" target="_blank">read more</a></p>https://plus.maths.org/content/os/issue42/features/wilson/index#comments42EulerEuler yeargeometryharmonic serieshistory of mathematicsinfinite seriespartition of a numbertopologyThu, 01 Mar 2007 00:00:00 +0000plusadmin2306 at https://plus.maths.org/contentCareer interview: Government Statistician

<p>How do you help a developing country get back on its feet? There's material aid of course, as well as political intervention; fair trade agreements and the like. But what may come as a surprise is that there's also statistics. For any country, measuring poverty, the growth of the economy, unemployment and other socio-economic factors are essential in deciding on and testing political
policy.</p><p><a href="https://plus.maths.org/content/career-interview-government-statistician" target="_blank">read more</a></p>https://plus.maths.org/content/career-interview-government-statistician#comments42career interviewHealth & SocietystatisticsThu, 01 Mar 2007 00:00:00 +0000plusadmin2431 at https://plus.maths.org/contentPuzzle page

<p>The hopeless prisoner is incarcerated in a dark, dank, forgotten cell. The days, months, and years are passing slowly. There are many more to come. The scene is familiar — at least from the movies. But there is usually an interesting mathematical sub-text. The prisoner has often been keeping track of the days by systems of marks on the cell wall. Nor is there anything novel about this human
tendency.<p><a href="https://plus.maths.org/content/outer-space-tally-ho" target="_blank">read more</a></p>https://plus.maths.org/content/outer-space-tally-ho#comments42arithmetichistory of mathematicsmathematics in sportouterspacetallyingThu, 01 Mar 2007 00:00:00 +0000plusadmin4795 at https://plus.maths.org/contentEditorial

If you've ever wanted to fly with the birds and swim with the fishes, get the inside knowledge on great London landmarks or just enjoy going to the movies, then this is the issue for you.
