Cover: Waves of diffusing electrons and holes are created when a semiconductor is illuminated with a periodically modulated laser beam. When the electrons and holes recombine, they emit infrared photons whose distribution (shown here in a computer simulation) can be measured and used to investigate the presence of defects inside the semiconductor. To find out more about this and other applications of diffusion waves, read Andreas Mandelis's article, which begins on page 29. (Cover image by Lena Nicolaides and Chris Feng.)

QCD Made Simple
Quantum chromodynamics is conceptually simple. Its realization in nature, however, is usually very complex. But not always -- Frank Wilczek

Diffusion Waves and Their Uses
 Diffusion waves lack wavefronts, can't be beamed, and don't travel very far, yet they form the basis of several new and revolutionary measurement technologies
-- Andreas Mandelis

Physicists in the New Era of Electronic Publishing
New electronic opportunities for scientific communication, and changes in how scientists use journals, are prompting a complete reevaluation of the roles of scientific journals and of scholarly societies like the APS -- James Langer
