Gases in one dimension -- not your typical desk toy

Physicists at Penn State University have performed the first laboratory experiment with a system of many colliding particles whose motion never becomes chaotic. The achievement provides a deeper understanding of conditions that govern the boundary between order and chaos in physical systems. The research also has the potential to improve the accuracy of modern communication and navigation systems, which rely on high-precision gyroscopes or force sensors. The research will be published in the 13 April issue of the journal Nature.
