Edge asked a range of high-profile "scientists and science-minded thinkers" the question: "What do you believe is true even though you cannot prove it?" None of them answered that they believe, but cannot prove, that Atlético de Madrid is a greater football club than Real Madrid, that Madrid house prices are too high, or that both God and Santa Claus exist, but nevertheless it's fascinating stuff to browse through (and there's 60,000 words of it).
