If you feel in need of some love this cold, dark February, then our images of the week might be just what you need. These hearts, created by Hamid Naderi Yeganeh, aren't drawn by hand, but defined by mathematical equations. Image by Hamid Naderi Yeganeh. Image by Hamid Naderi Yeganeh. The first curve consists of points in the plane whose coordinates satisfy for where ( is a zero of .) The second curve consists of points in the plane whose coordinates satisfy for .

The Cambridge Science Festival will kick off on March 9, and there is some great maths in the programme. Here are some mathsrelated events we are particularly excited about (in chronological order). Click on the links for price, booking and location information. For the full programme visit the festival website. And if you can't make it to Cambridge, then read the Plus articles by some of the speakers, linked to from the individual entries.

This short video features one of our favourite mathematicians, Corinna Ulcigrai from the University of Bristol, talking about mathematical billiards, its connection to chaos theory, and why mathematicians study it. You can also read our article Chaos on the billiard table, based on an interview with Ulcigrai. This video was originally produced for the Cambridge Mathematics Education Project.

Our image of the week shows Joana Grah, the levitating PhD student. Image by CarolaBibiane Schönlieb, Joana Grah and Kostas Papafitsoros. It's not supernatural powers that help Joana fly, but the equation on the blackboard. This partial differential equation can be used to fill in specific parts of an image based on what's around it. The process is called inpainting. For this image the equation was solved numerically to remove the stool Joana was sitting on. Image inpainting has wide ranging practical applications: from the restoration of satellite images, enhancement of medical images, the renovation of digital photographs and artwork, to special effects in images and videos. This image was created by CarolaBibiane Schönlieb, head of the Cambridge Image Analysis group at the Department of Applied Mathematics and Theoretical Physics, University of Cambridge, Joana Grah and Kostas Papafitsoros. It won the EPSRC science photo competition in 2013. You can read more about Schönlieb's work on inpainting in this Plus article. See here to see previous images of the week.

Our image of the week may look like a bird in flight... Image by Hamid Naderi Yeganeh. ...but it’s actually a collection of points in the plane given by a mathematical formula. To be precise, it’s a subset of the complex plane consisting of points of the form where and for and The image was created by Hamid Naderi Yeganeh.

Charlie taught mathematics for ten years in the state sector before joining MEI in 2000 to set up the pilot project that eventually became the Further Mathematics Support Programme. He became MEI's Chief Executive in 2010. Charlie is also Director of the National Centre for Excellence in the Teaching of Mathematics (NCETM), seconded from MEI on a halftime basis, and is regularly consulted by the government on mathematics education issues. "I am delighted for my work to have been recognised with this very special honour," says Charlie. "In recent years there have been unprecedented changes in mathematics education, particularly in curriculum development and the professional development of teachers, and it has been a privilege to have been in a position to influence them." MEI's Chairman Gerald Goodall says: "MEI plays a leading role in expanding opportunities for access to high quality mathematics education and we are very fortunate to benefit from Charlie’s leadership. MEI's trustees and staff are delighted to see Charlie's hard work and dedication recognised in this way." Congratulations Charlie!
