Exquisitely careful comparison of different decay charge states tells us that the kaon's violation of CP symmetry is, at least in part, attributable to standard‐model mechanisms rather than to some hypothetical superweak interaction.

Alternative approaches to magnetic fusion are moving ahead in many labs. One leading approach, the spherical torus, will be tested at two new facilities, just starting up at Princeton and Culham.

The long cylindrical fullerenes called carbon nanotubes are the smallest metallic wires yet made. A flurry of recent experiments is revealing the quantum properties of electron transport along these molecular wires.

In honor of the American Astronomical Society's centennial, we celebrate American astronomy's remarkable century of technological innovation and breathtaking, ever‐expanding discovery

Physicists should consider an alternative to the Turing‐machine model of computation.
