Quantum mechanics is famous for saying that a tree falling in a forest when there's no one there doesn't make a sound. Quantum mechanics also says that if anyone is listening, it interferes with and changes the tree. And ...

(PhysOrg.com) -- A group of physicists working out of Chalmers University of Technology in Gothenburg, Sweden, have succeeded in proving what was until now, just theory; and that is, that visible photons could be produced ...
(Phys.org) —All objects' colors are determined by the way that light scatters off of them. By manipulating the light scattering, scientists can control the wavelengths at which light is transmitted and reflected by objects, ...
(PhysOrg.com) -- Although the speed of light is constant in a vacuum, light slows down a small amount when traveling through other materials. While it's relatively easy to measure the speed of light in mediums made of one ...
Physicists at New York University have developed a technique to record three-dimensional movies of microscopic systems, such as biological molecules, through holographic video. The work, which is reported in Optics Express, ...
