How nitric acid overcame its fear of water with a little help from its friends
Whether it is a pond or raindrop, when a common nitrogen-containing acid encounters water's surface, it typically falls apart, dissociating into two charged particles. Except, sometimes it is able to hold ...

Virtual ghost imaging: New technique enables imaging even through highly adverse conditions
Ghost imaging (GI), and its even more oddly named cousin virtual ghost imaging (VGI), seem to contradict conventional wisdom by being able to image an object by simply counting photons in a "light bucket." This non-intuitive ...

Light
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.
