Photograph of a triangular prism, dispersing light Lamps as seen through a prism. In optics, a dispersive prism is an optical prism that is used to disperse light, that is, to separate light into its spectral components (the colors of the rainbow). Different wavelengths (colors) of light will be deflected by the prism at different angles. [1]
Causes of epiphora are any that cause either overproduction of tears or decreased drainage of tears, resulting in tearing onto the cheek. [2] This can be due to ocular irritation and inflammation (including trichiasis and entropion) or an obstructed tear outflow tract, which is divided according to its anatomical location (i.e., ectropion, punctal, canalicular or nasolacrimal duct obstruction).
The digital micromirror device, or DMD, is the microoptoelectromechanical system (MOEMS) that is the core of the trademarked Digital Light Processing (DLP) projection technology from Texas Instruments (TI). Texas Instrument's DMD was created by solid-state physicist and TI Fellow Emeritus Dr. Larry Hornbeck in 1987. [1]
Prism adaptation is a sensory-motor adaptation that occurs after the visual field has been artificially shifted laterally or vertically. It was first introduced by Hermann von Helmholtz in late 19th-century Germany as supportive evidence for his perceptual learning theory (Helmholtz, 1909/1962). [1]
LCD in a Texas Instruments calculator with top polarizer removed from device and placed on top, such that the top and bottom polarizers are perpendicular. As a result, the colors are inverted. The optical effect of a TN device in the voltage-on state is far less dependent on variations in the device thickness than that in the voltage-off state.
The Healy is a pseudoscientific device that claims to function via bioresonance, designed by Marcus Schmieke and Nuno Nina. [1] The device has been promoted via influencer marketing and multi-level marketing, while sellers make extreme healing claims without any proven benefits.
For a more intuitive explanation of the need for Bessel's correction, see § Source of bias. Generally Bessel's correction is an approach to reduce the bias due to finite sample size. Such finite-sample bias correction is also needed for other estimates like skew and kurtosis, but in these the inaccuracies are often significantly larger. To ...
Nier: Automata was review bombed in April 2017 by Chinese players demanding a translation of the game to Chinese, whom PC Gamer called "a powerful new voice". [6]Grand Theft Auto V was review bombed throughout June and July 2017 after publisher Take-Two Interactive issued a cease-and-desist against the widely used game modification tool OpenIV, as an attempt to stop single player and ...
