Integrated optics is a system of light-controlling components combined into a single device. The ultimate aim is to create miniature optical circuits similar to the silicon chips that have ...

Atom optics is the study of the wave-like properties of beams of atoms. Wave–particle duality — a central principle of quantum mechanics — implies that effects traditionally associated with waves, ...

DALLAS — An area stretching from Texas to Tennessee braced Wednesday for the possible arrival of freezing rain and snow even as some other parts of the U.S. hit by the plunging polar vortex this week ...
