Sodium atoms kicked by standing waves provide a new probe of quantum chaos. Several features of quantum chaos have been demonstrated in a system of sodium atoms interacting with a modulated standing wave of light. The system can be tuned continuously from a regime that can be described classically to one where a quantum description is necessary. Astronomical image processing may improve breast cancer diagnostics. Medical and astronomical researchers have collaborated to apply sophisticated image processing techniques to detect microcalcifications in mammograms.
X rays illuminate dynamics on near-atomic length scales.
A new program offers expertise from business and the arts to science majors. An apparently unique formal undergraduate program at Wisconsin's Carthage College may meet the challenge of preparing science students for the real world while not taking anything away from their science education.
