What do climate change, Kevin Bacon, the snowy tree cricket, Al Qaeda, HIV, the World Wide Web, and your address book have in common? They’ve all played a role in a major science discovery –- the hidden language of networks.

“CONNECTED: The Power of Six Degrees” is a new BBC documentary that unfolds the science behind the popular trivia game “Six Degrees of Kevin Bacon,” whose notion that anyone on the planet can be connected in just six steps of association was supposed to be an urban myth.

The film follows two young scientists, Harvard’s Laszlo Barabasi and Yahoo! Research’s very own Duncan Watts, as they work to uncover the pervasive law that nature uses to organize itself. By studying vast natural and man-made networks -- from the connections between Hollywood actors to the nervous system of a worm, the U.S. electric power grid and the WWW -- they discover that diverse systems share a common blueprint. It takes us from the hunt for Saddam Hussein to the front-lines of cancer research and shows that the Six Degrees principle doesn’t just relate to people but also to viruses, web pages, neurons, species, molecules, and even fashion.

Watts, a former Australian Navy officer with a passion for extreme rock climbing, was a professor at Columbia University at just 29. He launched the explosion in the new science of networks while studying crickets and the mechanism that allows them to chirp in unison. He’s the author of “Six Degrees: The Science of a Connected Age.” Yodel Anecdotal will post a full interview with Watts soon.

“CONNECTED: The Power of Six Degrees” premieres tomorrow night on the Science Channel. Check your local cable listings for times.
