Infrared
Infrared (IR), sometimes called infrared light, is electromagnetic radiation (EMR) with wavelengths longer than those of visible light. It is therefore invisible to the human eye. IR is generally understood to encompass wavelengths from around 1 millimeter (300 GHz) to the nominal red edge of the visible spectrum, around 700 nanometers (430 THz). Longer IR wavelengths (30 μm-100 μm) are sometimes included as part of the terahertz radiation range. Almost all black-body radiation from objects near room temperature is at infrared wavelengths. As a form of electromagnetic radiation, IR propagates energy and momentum, exerts radiation pressure, and has properties corresponding to both those of a wave and of a particle, the photon. It was long known that fires emit invisible heat; in 1681 the pioneering experimenter Edme Mariotte showed that glass, though transparent to sunlight, obstructed radiant heat. In 1800 the astronomer Sir William Herschel discovered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phonofilm
Phonofilm is an optical sound-on-film system developed by inventors Lee de Forest and Theodore Case in the early 1920s. Introduction In 1919 and 1920, Lee De Forest, inventor of the audion tube, filed his first patents on a sound-on-film process, DeForest Phonofilm, which recorded sound directly onto film as parallel lines. These parallel lines photographically recorded electrical waveforms from a microphone, which were translated back into sound waves when the movie was projected. Some sources say that DeForest improved on the work of Finnish inventor Eric Tigerstedt — who was granted German patent 309.536 on 28 July 1914 for his sound-on-film work — and on the Tri-Ergon Exchange, patented in 1919 by German inventors Josef Engl, Hans Vogt, and Joseph Massole. The Phonofilm system, which recorded synchronized sound directly onto film, was used to record vaudeville acts, musical numbers, political speeches, and opera singers. The quality of Phonofilm was poor at first, improved ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Audion Tube
The Audion was an electronic detecting or amplifying vacuum tube invented by American electrical engineer Lee de Forest in 1906.De Forest patented a number of variations of his detector tubes starting in 1906. The patent that most clearly covers the Audion is , Space Telegraphy', filed January 29, 1907, issued February 18, 1908 The link is to a reprint of the paper in the ''Scientific American Supplement'', Nos. 1665 and 1666, November 30, 1907 and December 7, 1907, p.348-350 and 354-356. It was the first triode, consisting of an evacuated glass tube containing three electrodes: a heated filament, a grid, and a plate. It is important in the history of technology because it was the first widely used electronic device which could amplify. A low power signal at the grid could control much more power in the plate circuit. Audions had more residual gas than later vacuum tubes; the residual gas limited the dynamic range and gave the Audion non-linear characteristics and erratic perf ...

Movietone News
Movietone News is a newsreel that ran from 1928 to 1963 in the United States. Under the name British Movietone News, it also ran in the United Kingdom from 1929 to 1986, in France also produced by Fox-Europa, in Australia and New Zealand until 1970, and Germany as Fox Tönende Wochenschau. History Movietone News evolved from an earlier newsreel established by Fox Films called Fox News which was founded in 1919. It produced silent newsreels. When Fox entered talkies in 1928 with '' Mother Knows Best'', the name Fox Movietone was applied to Fox's sound productions. In the U.S. as Fox Movietone News it produced cinema, sound newsreels from 1928 to 1963, and from 1929 to 1986 in the UK (for much of that time as British Movietone News), as well as 1929 to 1975 in Australia. One of the earliest in the series featured ''George Bernard Shaw Talks to Movietone News'', released on June 25, 1928. One of the known early producers of these newsreels was Abraham Harrison also known as Harry, f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Film Registry
The National Film Registry (NFR) is the United States National Film Preservation Board's (NFPB) collection of films selected for preservation, each selected for its historical, cultural and aesthetic contributions since the NFPB’s inception in 1988. History Through the 1980s, several prominent filmmakers and industry personalities in the United States, such as Frank Capra and Martin Scorsese, advocated for Congress to enact a film preservation bill in order to avoid commercial modifications (such as pan and scan and editing for TV) of classic films, which they saw as negative. In response to the controversy over the colorization of originally black and white films in the decade specifically, Representatives Robert J. Mrazek and Sidney R. Yates introduced the National Film Preservation Act of 1988, which established the National Film Registry, its purpose, and the criteria for selecting films for preservation. The Act was passed and the NFR's mission was subsequently reau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gallagher And Shean
Gallagher & Shean was a highly successful musical comedy double act in vaudeville and on Broadway in the 1910s and 1920s, consisting of Ed Gallagher (1873–1929) and Al Shean (1868–1949); Shean was the maternal uncle of the Marx Brothers. Career Both comedians were relatively obscure vaudeville performers until they teamed up in 1910. Gallagher and Shean first joined forces during the tour of ''The Rose Maid'' in 1912, but they quarreled and split up two years later, in 1914. They next appeared together in 1920, to star in the Shubert Brothers' production of the highly successful ''Cinderella on Broadway'', through the efforts of Shean's sister, Minnie Marx (mother of the Marx Brothers). This pairing lasted until 1925 and led to their fame. Gallagher and Shean remain best known for their theme song "Mister Gallagher and Mister Shean", which was a hit in the 1922 ''Ziegfeld Follies''.
