Polarization — ( Brit. polarisation) is a property of waves that describes the orientation of their oscillations. For transverse waves, it describes the orientation of the oscillations in the plane perpendicular to the wave s direction of travel. Longitudinal… … Wikipedia
Photographic filter — Four photographic filters. Clockwise, from top left, an infrared hot mirror filter, a polarising filter, and a UV filter. The larger filter is a polariser for Cokin style filter mounts. In photography and videography, a filter is a camera… … Wikipedia
Twisted nematic field effect — The twisted nematic effect ( TN effect ) in liquid crystals is claimed to be first discovered by James Fergason in 1970 at the International Liquid Xtal Company in Kent Ohio. Fergason patented his work at about the same time that the Central… … Wikipedia
Bell's theorem — is a theorem that shows that the predictions of quantum mechanics (QM) are not intuitive, and touches upon fundamental philosophical issues that relate to modern physics. It is the most famous legacy of the late physicist John S. Bell. Bell s… … Wikipedia
