Alaska Science: The
Chaos Behind the Wall Socket by Ned Rozell - An Alaska
college professor was not surprised when the lights went out
over the northern tier of the U.S. and southeast Canada in mid-August.
David Newman studies the workings
of complex, chaotic systems as part of his research at the University
of Alaska Fairbanks. He and three colleagues wrote a paper in
December 2002 about "cascading" power blackouts similar
to the largest ever, which affected 50 million people on August
14, 2003.
Newman is a physics professor
who uses a variety of computers to model gargantuan interconnected
systems that fail catastrophically, including power transmission
grids, intercity travel halted during traffic jams, and huge

that bring power to homes in much of North America.-
