WHAT IS QUITE INTERESTING?.

Ignorance is like a delicate, exotic fruit; touch it and the bloom has gone.

OSCAR WILDE.

QI stands for Quite Interesting. We do not claim to be Quite Right.

If you have better answers to any of these questions, or if you have new questions of your own, we'd love to hear from you. Join us online at www.qi.com.

The book is the distillation of many people's attempts to understand the world around them, but owes most of all to the QI research team, a collection of people with high curiosity levels, low boredom thresholds and a knack for asking difficult questions. Special thanks are due to Piers Fletcher, Justin Gayner, Chris Gray, James Harkin, Mat Coward, Justin Pollard, Garrick Alder, Molly Oldfield and Dan Schreiber. They'd make the world's best pub quiz team.

We also doff our caps to the professionalism and taste of our publishers Julian Loose, Stephen Page and their colleagues at Faber & Faber; to our production partners, Sarah Chaloner, Beatrice Gay and the team at Talkback Thames; and to Mark Freeland and Peter Fincham at the BBC, for having the courage of their convictions.

John le Carre once complained that having a book made into a movie was 'like seeing your oxen turned into bouillon cubes'. With that in mind, we should acknowledge the hundreds of scientists, philosophers, historians, inventors, saints and visionaries whose original work we have diced, skimmed, boiled and pureed to make the book you now hold in your hands.
