James Burke takes a look at 2,000 years of human ingenuity. In the fifth of ten historical detective stories, he searches for the clues that link yesterday's amazing inventions to our modern-day world. This week he asks: ' What's the connection between the Caliph of Baghdad's stomach ache and medieval Nuremberg, or between steel clocksprings and gingerbread men - and what does that connection do to our working day?
