The Internet's mind-boggling flow of data that circulates so freely "in the cloud" does much of its real-world traveling beneath the sea in bundles of fiber-optic cable. Sets sail on the Leon Thevenin as a repair team identifies a damaged length of cable on the floor of the North Sea and then painstakingly splices in a new section. Also, discusses high-bandwidth digital developments such as naked-eye 3-D video and describes the principles of applied fiber-optic physics, cable-manufacturing processes, and cable-laying techniques that are making such advanced Internet technology a reality.
