The modeling of chaotic phenomena has provided many colorful images, but only rarely has it captured the unusual physical behavior found in the realm of quantum mechanics. The cover image is a Poincaré section, or a stroboscopic snapshot, of a chaotic attractor describing the motion of electrons ...
The distribution of the chemical elements in our galaxy serves as a "fossil record" of its evolutionary history
Wealthier nations are not always healthier, and efforts to improve health can be swamped by the effects of inequality and conflict
A new class of device based on electron spin, rather than on charge, may yield the next generation of microelectronics
