Alex Bellos studied mathematics and philosophy at uni, but started his career as a reporter - eventually moving to Rio de Janeiro as The Guardian's South American correspondant. He's since presented a five-part series on Brazil for the BBC - called Inside Out Brazil - and his short films about the Amazon have been broadcast on the BBC, More 4 and Al Jazeera International. He's written Futebol, The Brazillian Way of Life; ghostwritten Pelé, The Autobiography. Alex came in to Google London to discuss some of the ideas in his latest book, Alex's Adventurers in Numberland (US title: Here's Looking at Euclid).
