One problem in dealing with weapons of mass destruction is that they are well hidden. The key to finding them may be to change the methods we use to look. One such method is taking shape in a lab in the basement of Small ...

Sometimes in shallow water, a type of wave can form that is much more stable than ordinary waves. Called solitons, these phenomena emerge as solitary waves and can travel long distances while maintaining their shape and speed, ...
Since the first use of electric lamps in the 19th century, society hasn't looked back. Homes and streets are lit at all hours so that people can go about their business when they'd once have been asleep. Besides the obvious ...

Light is electromagnetic radiation, particularly radiation of a wavelength that is visible to the human eye (about 400–700 nm, or perhaps 380–750 nm.) In physics, the term light sometimes refers to electromagnetic radiation of any wavelength, whether visible or not.
Three primary properties of light are:
Light, which exists in tiny "packets" called photons, exhibits properties of both waves and particles. This property is referred to as the wave–particle duality. The study of light, known as optics, is an important research area in modern physics.
