In Earth's Magnetic Pas de Deux, the Inner Core Leads
Subtle shifts over time in historical seism ological data may teach us as much about Earth as the most modern seismograph. Case in point: the recent discovery that Earth's inner core rotates faster than the planet's mantle and crust.
One‐Dimensional Systems Show Signs of Interacting Electrons
Do electrons in one dimension interact in a way prescribed by the Luttinger‐liquid theory? To answer that question, researchers are studying the tunneling through barriers in one‐dimensional wires and across the edges of fractional quantum Hall states. A Bell Labs group has intriguing new results.
LEP is Now Making Pairs of W Bosons
CERN's big electron‐positron collider has finally crossed the energy threshold for producing pairs of the, heavy bosons that mediate the weak force.

How Things Break
Solids fail through the propagation of cracks, whose speed is controlled by instabilities at the smallest scales.
Extrasolar Planets
Astronomers have recently found planets orbiting nearby stars, ending centuries of speculation and opening up an exciting, already busy, field of research.
The Discovery of Superconductivity
Though Kamerlingh Onnes always stressed the importance of precise measurement in his work, it was an accident that led to the first detection of superconductivity.
Memories of Richard Feynman
A ‘new’ set of lectures—on computation—by one of the more colorful characters in modern physics, gives rise to these reminiscences by an Englishman in Richard's court.
