The Long Chain
James Burke takes a look at 2,000 years of human ingenuity. In the seventh 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 Lloyd's of London and the Glasgow gasworks, or between the invention of the gin-and-tonic and nylon stockings - and how does that connection mould the shape of your life?'
