Plus has teamed up with the Royal Society Summer Science Exhibition 2011 to reveal the maths behind some of the science on show. The Maths Inside project is run by the Mathematics Promotion Unit (a collaboration between the London Mathematical Society and the Institute of Mathematics and its Applications) in conjunction with Plus and the Royal Society.
We have chosen two exhibits from this year's participants and produced postcards for people to pick up at the stand, accopmanied by Plus articles to reveal some of the the maths behind them. You can read the articles by clicking on the links below and if you can't make it to the exhibition yourself, you can also download pdfs of the postcards.
