For signals barely larger than the noise in a system, measurement is generally a trade-off between speed and precision. Averaging over several measurements reduces the influence of noise but takes (a lot of) time. That could ...

Researchers at Johannes Kepler University in Linz have been investigating the physical properties of Cu(110), a surface attained when cutting a single copper crystal in a specific direction, for several years. Their most ...
A team of researchers has built an intelligent sensor—the size of about 1/1000 of the cross-section of a human hair—that can simultaneously detect the intensity, polarization and wavelength of light, tapping into the ...

Shine a flashlight into a murky pond water and the beam won't penetrate very far. Absorption and scattering rapidly diminishes the intensity of the light beam, which loses a fixed percentage of energy per unit distance traveled. ...
