Alex Bellos

Rev Richard Coles and Andrea Catherwood with maths writer Alex Bellos, English-speaker Caroline Sarll who decided to bring her children up to be bilingual, Charlie Corr whose childhood dream came true when he met Pele, Frank McCauley from lowly Salford City FC who've caught the eye of Manchester United's famous 'Class of '92', Ken Jones who was caught in an avalanche, and Simon Duncan and Mark Atkinson whose band's name earned them a Banksy. Plus the Inheritance Tracks of writer and broadcaster Judy Finnigan.

Alex Bellos's new book is Alex Through the Looking-Glass. His first maths book was the hugely acclaimed Alex's Adventures in Numberland. He set up favouritenumber.net, a global survey to find the world's favourite number. His book on Brazilian football Futebol: The Brazilian Way of Life has been revised and updated with a new chapter for the 2014 World Cup. He ghostwrote Pele: The Autobiography. He blogs about maths for The Guardian.

On June 25 1966, 13 year-old Charlie Corr ran onto the pitch at Hampden to meet his football idol Pele. The moment was captured on camera and the picture was printed recently in the Sunday Mail in Scotland.

Caroline Sarll and her husband are both native English speakers but she decided to bring up their two daughters to be bilingual in German.

Ken Jones survived an avalanche in Transylvania in 2003. His book Darkness Descending is out now.

Simon Duncan and Mark Atkinson's original band name was Exit Via The Giftshop. They changed it to Brace Yourself and gained a Banksy
