Color photography is photography that uses media capable of representing colors, which are traditionally produced chemically during the photographic processing phase. By contrast, black-and-white (monochrome) photography records only a single channel of luminance (brightness) and uses media capable only of showing shades of gray.

In color photography, light-sensitive chemicals or electronic sensors record color information at the time of exposure. This is usually done by analyzing the spectrum of colors into three channels of information, one dominated by red, another by green and the third by blue, in imitation of the way the normal human eye senses color. The recorded information is then used to reproduce the original colors by mixing together various proportions of red, green and blue light (RGB color, used by video displays, digital projectors and some historical photographic processes), or by using dyes or pigments to remove various proportions of the red, green and blue which are present in white light (CMY color, used for prints on paper and transparencies on film).

Sir Isaac Newton PRS MP (25 December 1642 – 20 March 1727 [NS: 4 January 1643 – 31 March 1727]) was an English physicist, mathematician, astronomer, natural philosopher, alchemist, and theologian, who has been "considered by many to be the greatest and most influential scientist who ever lived." His monograph Philosophiæ Naturalis Principia Mathematica, published in 1687, lays the foundations for most of classical mechanics. In this work, Newton described universal gravitation and the three laws of motion, which dominated the scientific view of the physical universe for the next three centuries. Newton showed that the motions of objects on Earth and of celestial bodies are governed by the same set of natural laws, by demonstrating the consistency between Kepler's laws of planetary motion and his theory of gravitation, thus removing the last doubts about heliocentrism and advancing the Scientific Revolution.

Joel David Coen (born November 29, 1954) and Ethan Jesse Coen (born September 21, 1957) known together professionally as the Coen brothers, are American filmmakers. Their films include Blood Simple, Fargo, The Big Lebowski, O Brother, Where Art Thou?, No Country for Old Men, and True Grit.

The brothers write, direct and produce their films jointly, although until recently Joel received sole credit for directing and Ethan for producing. They often alternate top billing for their screenplays while sharing film credits for editor under the alias Roderick Jaynes.

Joel and Ethan Coen, of Jewish heritage, grew up in a Jewish community in St. Louis Park, Minnesota, a suburb of Minneapolis. Their father, Edward, was an economist at the University of Minnesota, and their mother, Rena, an art historian at St. Cloud State University.

When they were children, Joel saved money from mowing lawns to buy a Vivitar Super 8 camera. Together, the brothers remade movies they saw on television with a neighborhood kid, Mark Zimering ("Zeimers"),^{[citation needed]} as the star. Their first attempt was a romp titled, Henry Kissinger, Man on the Go. Cornel Wilde's The Naked Prey (1966) became their Zeimers in Zambia, which also featured Ethan as a native with a spear.

Edward Turner (24 January 1901 – 15 August 1973) was a British motorcycle designer. He was born in Camberwell in the London Borough of Southwark, on the day King Edward VII was proclaimed King. In 1915, Turner had his first ride on a motorcycle, a Light Tourist New Imperial.

On 16 April 1925 "The Motor Cycle" published drawings by Turner of an OHC single he had designed, using a series of vertically stacked gears to drive the overhead camshaft. A subsequent redesign used bevel gears to drive a vertical camshaft, operating the valves through rockers. The only shared aspects of the two designs were the bore and stroke, 74 × 81 mm (2.9 × 3.2 in), with the barrel being sunk into the crankcases. The head could be removed from either design complete with undisturbed valve gear.

Turner built his first bike in 1927, using his second design, a 350 cc OHC single. The Motor Cycle published a photograph of Turner's patented engine, mounted in his motorcycle called the Turner Special. The Special was registered for road use with the London County Council as YP 9286. It used Webb forks, and a three-speed Sturmey-Archer gearbox.
