Faith in Numbers
James Burke takes a look at 2,000 years of human ingenuity. In the fourth of ten historical detective stories, he searches for the clues that link yesterday's amazing inventions to the world we live in. What's so special about French knickers that makes it possible to print the radio TIMES? What's the connection between the rats of Troves and the American Census of 1890? And why did everyone get a soaking when they went to dinner with the Archbishop of Salzburg?
