Episode 1 of James Burke's most well-known series "Connections" which explores the surprising and unexpected ways that our modern technological world came into existence. Each episode investigates the background of usually one particular modern invention and how it came into being. These explorations are an attempt to locate the "connections" between various historical figures who seemingly had nothing to do with each other in their own times, however once connected, these same figures combined to produce some of the most profound impacts on our modern day world; in a "1+1=3" type of way.
It is this type of investigation that is the main idea behind the Knowledge Web project; whereby sophisticated software is used to attempt to discover these subtle connections automatically. See
