Materials Mimic Mechanics
BERKELEY, Calif., July 21, 2009 -- Astronomical phenomena such as black holes could be studied in a tabletop laboratory setting if the nascent field of artificial optical materials is combined with celestial mechanics, researchers say. “We have introduced a new class of specially designed optical media that can mimic the periodic, quasiperiodic and chaotic motions observed in celestial objects that have been subjected to complex gravitational fields,” said University of California, Berkeley, professor Xiang Zhang, a faculty...
