In celebration of:
Charles' 2009 Nobel Prize in Physics
Mankind has communicated using light for aeons: a wave of the hand, a nod of the head, or a wink of the eye. Light gives us the power to communicate over vast distances, but generally travels in straight lines, so for many years long distance communication was dominated by copper conductors carrying electrical signals that could be steered over the horizon and around corners, even under the oceans. With the invention of the laser in 1960, researchers in Harlow started to explore a variety of ways of guiding optical signals. Their aim was to exploit the potentially vast information capacity of light.
Hear a story of cul-de-sacs and competing microwave technologies, how the prophetic vision of Charles Kao in the mid 1960s, was developed by an ever increasing community of skilled scientists through the next decades, to become the incredible global optical fibre communication network of today. Explore how different the world would be today, if Charles had been less obsessed, and the doubters had been heeded.
