Issues

Researchers have made artificial structures that block light near visible wavelengths. Eventually, they hope to trap light within the structure or guide it along a prescribed path to make lasers, switches, waveguides and interconnects tor photonic integrated circuits.

In a two‐dimensional geometry, burning paper develops a fingering instability. Is this phenomenon related to viscous fingering, dendritic growth and etectrodeposition?

Research on three questions is improving instruction: What is involved in understanding physics? What do students bring to physics classes? How do they respond to what they are taught?

Modern surface physics is transforming the black art of catalysis, revealing a fascinating choreography followed by reacting atoms and molecules.

The quantum correlation of paired photons produced in nonlinear optical crystals promises metrologists something of a free lunch: absolute measurements that don't require absolute standards.
