It requires only a little processing power, but it's a giant leap for robotkind: engineers at the University of Southampton have developed a way of equipping spacecraft and satellites with human-like reasoning capabilities, which will enable them to make important decisions for themselves.

It's been nearly 18 months since the Large
Hadron Collider at CERN started up and scientists are eagerly awaiting their first glimpse into the
cosmic mysteries it was designed to explore. But when can we realistically
expect the first ground-breaking discoveries to come through? Last week, John Ellis,
outgoing leader of the theory division at CERN, addressed an audience
of physicists at the University of Cambridge to update them on the
current state of play. *Plus* went along and also managed to
catch Ellis for a quick interview.

Many people like mathematics because it gives definite answers. Things are either true or false, and true things seem true in a very fundamental way. But it's not quite like that. You can actually build different versions of maths in which statements are true or false depending on your preference. So is maths just a game in which we choose the rules to suit our purpose? Or is there a "correct" set of rules to use? We find out with the mathematician Hugh Woodin.

This book is a mixture between an encyclopedia and a collection of intriguing ideas. In some sense, it's a plain English encyclopedia of maths, embellished with some examples for entertainment. So whether you're trying to get at the "true" meaning of something textbooks only define using passionless symbols, or are looking for a little diversion before going to sleep, this book can give you both.

That geometry should be relevant to physics is no surprise — after all, space is the arena in which physics happens. What is surprising, though, is the extent to which the geometry of space actually determines physics and just how exotic the geometric structure of our Universe appears to be. *Plus* met up with mathematician Shing-Tung Yau to find out more.

This book tells the fascinating story of strange geometric objects that have achieved some fame outside of maths and even inspired a Woody Allen joke: they're called *Calabi-Yau manifolds*. When *Plus* recently interviewed one of its authors he was adamant that maths should be brought to the masses without dumbing down or glossing over the tricky parts. And this is just what this books sets out to achieve.

Plus bumped into an old friend at the International Congress of Mathematicians this year: Keith Mansfield is the author of the Johnny Mackintosh series and commissioning editor for mathematics at Oxford University Press at the same time. In this interview he tells us how his he's built a career around his two talents, writing and maths.

Statistics are emotive — to some they are just lies, to others perplexing, some fear their power to reduce us all to a single number, while yet others (politicians and journalists especially) like to endow them with qualities like "damning" or "deathly". So what are (or should it be "is"?) statistics all about? And what do we need to be wary of? This little comic-style book (from the *Introducing* series) provides some friendly answers in 176 pages and a handy A6 format.
