Charcot Island
Charcot Island or Charcot Land is an island administered under the Antarctic Treaty System, long and wide, which is ice covered except for prominent mountains overlooking the north coast. Charcot Island lies within the Bellingshausen Sea, west of Alexander Island, and about north of Latady Island. A notable landmark of the island is its northernmost point, Cape Byrd. History Charcot Island was discovered on 11 January 1910 by the French Antarctic Expedition under Jean-Baptiste Charcot, who, at the insistence of his crew and the recommendation of Edwin S. Balch and others, named it Charcot Land. He did so with the stated intention of honoring his father, Jean-Martin Charcot, a famous French physiciaThe insularity of Charcot Land was proved by Sir Hubert Wilkins, who flew around it on 29 December 1929. 2009 Collapse of ice bridge The ice bridge holding the Wilkins Ice Shelf to the Antarctic coastline and Charcot Island was long but only wide at its narrowest point – in 19 ...

Greyscale
In digital photography, computer-generated imagery, and colorimetry, a grayscale image is one in which the value of each pixel is a single sample representing only an ''amount'' of light; that is, it carries only intensity information. Grayscale images, a kind of black-and-white or gray monochrome, are composed exclusively of shades of gray. The contrast ranges from black at the weakest intensity to white at the strongest. Grayscale images are distinct from one-bit bi-tonal black-and-white images, which, in the context of computer imaging, are images with only two colors: black and white (also called ''bilevel'' or ''binary images''). Grayscale images have many shades of gray in between. Grayscale images can be the result of measuring the intensity of light at each pixel according to a particular weighted combination of frequencies (or wavelengths), and in such cases they are monochromatic proper when only a single frequency (in practice, a narrow band of frequencies) is captu ...

Jean-Martin Charcot
Jean-Martin Charcot (; 29 November 1825 – 16 August 1893) was a French neurologist and professor of anatomical pathology. He worked on hypnosis and hysteria, in particular with his hysteria patient Louise Augustine Gleizes. Charcot is known as "the founder of modern neurology",Lamberty (2007), p. 5 and his name has been associated with at least 15 medical eponyms, including various conditions sometimes referred to as Charcot diseases. Charcot has been referred to as "the father of French neurology and one of the world's pioneers of neurology". His work greatly influenced the developing fields of neurology and psychology; modern psychiatry owes much to the work of Charcot and his direct followers.Bogousslavsky (2010), p. 7 He was the "foremost neurologist of late nineteenth-century France" and has been called "the Napoleon of the neuroses". Personal life Born in Paris, Charcot worked and taught at the famous Pitié-Salpêtrière Hospital for 33 years. His reputation as an ...

Territorial Claims In Antarctica
Seven sovereign states – Argentina, Australia, Chile, France, New Zealand, Norway, and the United Kingdom – have made eight territorial claims in Antarctica. These countries have tended to place their Antarctic scientific observation and study facilities within their respective claimed territories; however, a number of such facilities are located outside of the area claimed by their respective countries of operation, and countries without claims such as China, India, Italy, Pakistan, Russia, South Africa ( SANAE), Ukraine, and the United States have constructed research facilities within the areas claimed by other countries. There are overlaps among the territories claimed by Argentina, Chile, and the United Kingdom. History Spanish claims According to Argentina and Chile, the Spanish Crown had claims on Antarctica. The ''capitulación'' (governorship) granted to the conquistador Pedro Sánchez de la Hoz in 1539 by the King of Spain, Charles V, explicitly included ...
