## News from the world of Maths

*Math/Maths*, produced by Peter Rowlett and Samuel Hansen. Peter talks to Ruby Childs, a recent maths graduate who is interested in what makes people like mathematics for an essay she is writing. She's particularly interested in why people chose to study maths further. You can listen to the podcast and join the debate!

The Millennium Mathematics Project (of which Plus is a part) has just launched the Maths and Sport: Countdown to the Games website at http://sport.maths.org.

John D. Barrow is continuing his public lecture tour to promote his new Book of Universes. You can catch him at Gresham College in London on March 1st (admission free) and at the Bath Literary Festival on February 27th (admission £7, concession £6).

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.

If you're in London on Tuesday the 15th of February, then why not take a journey into other worlds with John D. Barrow at the Royal Institution? Barrow will tell a story that revolves around a single extraordinary fact: that Albert Einstein's famous theory of relativity describes a series of entire universes.

Squeamish about cuts and scrapes? Maths can help you feel better.

Here's a fact: take the year you were born in (only the last two digits, as in '85), add your age and then (probably) add 1. The answer is ... 111!

This seems to have been making the rounds lately. Some people marvel at the fact that the answer is always 111 no matter how old you are and others think that 2011 is the only year in which this will work. Looks like mathematical magic!

Quantum mechanics is usually associated with weird and counterintuitive phenomena we can't observe in real life. But it turns out that quantum processes can occur in living organisms, too, and with very concrete consequences. Some species of birds, for example, use quantum mechanics to navigate. Last year we talked to physicists Simon Benjamin and Erik Gauger, and found out that studying these little creatures' quantum compass may help us achieve the holy grail of computer science: building a quantum computer.
