## News from the world of Maths

Space is three-dimensional ... or is it? When we spoke to theoretical physicist David Berman in October this year we found out that in fact, we are all used to living in a curved, multidimensional universe. And a mathematical argument might just explain how those higher dimensions are hidden from view.

Want to stop your brain from rusting this Christmas? Then visit our sister project NRICH, which received a major make-over this year and now has a beautiful new website. NRICH is aimed at students and teachers of maths of all ages and backgrounds. It offers challenging and engaging activities that develop mathematical thinking and problem-solving skills and show rich mathematics in meaningful contexts.

The Isaac Newton Institute celebrates its 20th birthday this year, having opened in July 1992. To celebrate we had a rare glimpse behind its venerable doors to explore some of the research programmes that have been held there. As you'll see, what started out as abstract mathematics scribbled on the back of a napkin can have major impact in the real world.
