Life On Earth (documentary)
''Life on Earth: A Natural History by David Attenborough'' is a British television natural history series made by the BBC in association with Warner Bros. Television and Reiner Moritz Productions. It was transmitted in the UK from 16 January 1979. During the course of the series presenter David Attenborough, following the format established by Kenneth Clark's ''Civilisation'' and Jacob Bronowski's ''The Ascent of Man'' (both series which he designed and produced as director of BBC2), travels the globe in order to trace the story of the evolution of life on the planet. Like the earlier series, it was divided into 13 programmes (each of around 55 minutes' duration). The executive producer was Christopher Parsons and the music was composed by Edward Williams. Highly acclaimed, it is the first in Attenborough's ''Life'' series of programmes and was followed by ''The Living Planet'' (1984). It established Attenborough as not only the foremost television naturalist, but also an ic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nature Documentary
A nature documentary or wildlife documentary is a genre of documentary film or series about animals, plants, or other non-human living creatures, usually concentrating on video taken in their natural habitat but also often including footage of trained and captive animals. Sometimes they are about wildlife or ecosystems in relationship to human beings. Such programmes are most frequently made for television, particularly for public broadcasting channels, but some are also made for the cinema medium. The proliferation of this genre occurred almost simultaneously alongside the production of similar television series. History In cinema Robert J. Flaherty's 1922 film ''Nanook of the North'' is typically cited as the first feature-length documentary. Decades later, Walt Disney Productions pioneered the serial theatrical release of nature-documentaries with its production of the True-Life Adventures series, a collection of fourteen full length and short subject nature films from 1948 to ...

Life
Life is a quality that distinguishes matter that has biological processes, such as signaling and self-sustaining processes, from that which does not, and is defined by the capacity for growth, reaction to stimuli, metabolism, energy transformation, and reproduction. Various forms of life exist, such as plants, animals, fungi, protists, archaea, and bacteria. Biology is the science that studies life. The gene is the unit of heredity, whereas the Cell (biology), cell is the structural and functional unit of life. There are two kinds of cells, prokaryotic and eukaryotic, both of which consist of cytoplasm enclosed within a membrane and contain many biomolecules such as proteins and nucleic acids. Cells reproduce through a process of cell division, in which the parent cell divides into two or more daughter cells and passes its genes onto a new generation, sometimes producing genetic variation. Organisms, or the individual entities of life, are generally thought t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elizabeth II
Elizabeth II (Elizabeth Alexandra Mary; 21 April 1926 – 8 September 2022) was Queen of the United Kingdom and other Commonwealth realms from 6 February 1952 until her death in 2022. She was queen regnant of 32 sovereign states during her lifetime, and was head of state of 15 realms at the time of her death. Her reign of 70 years and 214 days was the longest of any British monarch and the longest verified reign of any female monarch in history. Elizabeth was born in Mayfair, London, as the first child of the Duke and Duchess of York (later King George VI and Queen Elizabeth The Queen Mother). Her father acceded to the throne in 1936 upon the abdication of his brother Edward VIII, making the ten-year-old Princess Elizabeth the heir presumptive. She was educated privately at home and began to undertake public duties during the Second World War, serving in the Auxiliary Territorial Service. In November 1947, she married Philip Mountbatten, a former prince ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Channel 4
Channel 4 is a British free-to-air public broadcast television network operated by the state-owned enterprise, state-owned Channel Four Television Corporation. It began its transmission on 2 November 1982 and was established to provide a fourth television service in the United Kingdom. At the time, the only other channels were the television licence, licence-funded BBC One and BBC Two, and a single commercial broadcasting network ITV (TV network), ITV. The network's headquarters are based in London and Leeds, with creative hubs in Glasgow and Bristol. It is publicly owned and advertising-funded; originally a subsidiary of the Independent Broadcasting Authority (IBA), the station is now owned and operated by Channel Four Television Corporation, a public corporation of the Department for Digital, Culture, Media and Sport, which was established in 1990 and came into operation in 1993. Until 2010, Channel 4 did not broadcast in Wales, but many of its programmes were re-broadcast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ad Lib
In music and other performing arts, the phrase (; from Latin for 'at one's pleasure' or 'as you desire'), often shortened to "ad lib" (as an adjective or adverb) or "ad-lib" (as a verb or noun), refers to various forms of improvisation. The roughly synonymous phrase ('in accordance with ne'sgood pleasure') is less common but, in its Italian form , entered the musical '' lingua franca'' (see below). The phrase "at liberty" is often associated mnemonically (because of the alliteration of the ''lib-'' syllable), although it is not the translation (there is no cognation between and ). Libido is the etymologically closer cognate known in English. Music As a direction in sheet music, indicates that the performer or conductor has one of a variety of types of discretion with respect to a given passage: *to play the passage in free time rather than in strict or " metronomic" tempo (a practice known as ''rubato'' when not expressly indicated by the composer); *to improvise a ...

Thumb
The thumb is the first digit of the hand, next to the index finger. When a person is standing in the medical anatomical position (where the palm is facing to the front), the thumb is the outermost digit. The Medical Latin English noun for thumb is ''pollex'' (compare ''hallux'' for big toe), and the corresponding adjective for thumb is ''pollical''. Definition Thumb and fingers The English word ''finger'' has two senses, even in the context of appendages of a single typical human hand: # Any of the five terminal members of the hand. # Any of the four terminal members of the hand, other than the thumb Linguistically, it appears that the original sense was the first of these two: (also rendered as ) was, in the inferred Proto-Indo-European language, a suffixed form of (or ), which has given rise to many Indo-European-family words (tens of them defined in English dictionaries) that involve, or stem from, concepts of fiveness. The thumb shares the following with each of the o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rwanda
Rwanda (; rw, u Rwanda ), officially the Republic of Rwanda, is a landlocked country in the Great Rift Valley of Central Africa, where the African Great Lakes region and Southeast Africa converge. Located a few degrees south of the Equator, Rwanda is bordered by Uganda, Tanzania, Burundi, and the Democratic Republic of the Congo. It is highly elevated, giving it the soubriquet "land of a thousand hills", with its geography dominated by mountains in the west and savanna to the southeast, with numerous lakes throughout the country. The climate is temperate to subtropical, with two rainy seasons and two dry seasons each year. Rwanda has a population of over 12.6 million living on of land, and is the most densely populated mainland African country; among countries larger than 10,000 km2, it is the fifth most densely populated country in the world. One million people live in the Capital city, capital and largest city Kigali. Hunter-gatherers settled the territory in the St ...

Dian Fossey
Dian Fossey (, January 16, 1932 – ) was an American primatologist and conservationist known for undertaking an extensive study of mountain gorilla groups from 1966 until her murder in 1985. She studied them daily in the mountain forests of Rwanda, initially encouraged to work there by paleoanthropologist Louis Leakey. ''Gorillas in the Mist'', a book published two years before her death, is Fossey's account of her scientific study of the gorillas at Karisoke Research Center and prior career. It was adapted into a 1988 film of the same name.Ware, Susan; Braukman, Stacy (2004). ''Notable American Women: A Biographical Dictionary, Volume 5''. Radcliffe Institute for Advanced Study. pp. 220–1. . Fossey was a leading primatologist, and a member of the "Trimates", a group of female scientists recruited by Leakey to study great apes in their natural environments, along with Jane Goodall who studies chimpanzees, and Biruté Galdikas, who studies orangutans. Fossey spent 20 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountain Gorilla
The mountain gorilla (''Gorilla beringei beringei'') is one of the two subspecies of the eastern gorilla. It is listed as endangered by the IUCN as of 2018. There are two populations: One is found in the Virunga volcanic mountains of Central/ East Africa, within three National Parks: Mgahinga, in southwest Uganda; Volcanoes, in northwest Rwanda; and Virunga, in the eastern Democratic Republic of Congo (DRC). The other population is found in Uganda's Bwindi Impenetrable National Park. Some primatologists speculate the Bwindi population is a separate subspecies, though no description has been finalized. As of June 2018, there were more than 1,000 individuals. Evolution, taxonomy, and classification Mountain gorillas are descendants of ancestral monkeys and apes found in Africa and Arabia during the start of the Oligocene epoch (34–24 million years ago). The fossil record provides evidence of the hominoid primates (apes) found in east Africa approximately 22–32 million ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neuroethology
Neuroethology is the evolutionary and comparative approach to the study of animal behavior and its underlying mechanistic control by the nervous system. It is an interdisciplinary science that combines both neuroscience (study of the nervous system) and ethology (study of animal behavior in natural conditions). A central theme of neuroethology, which differentiates it from other branches of neuroscience, is its focus on behaviors that have been favored by natural selection (e.g., finding mates, navigation, locomotion, and predator avoidance) rather than on behaviors that are specific to a particular disease state or laboratory experiment. Neuroethologists hope to uncover general principles of the nervous system from the study of animals with exaggerated or specialized behaviors. They endeavor to understand how the nervous system translates biologically relevant stimuli into natural behavior. For example, many bats are capable of echolocation which is used for prey capture and navi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coelacanth
The coelacanths ( ) are fish belonging to the order Actinistia that includes two extant species in the genus ''Latimeria'': the West Indian Ocean coelacanth (''Latimeria chalumnae''), primarily found near the Comoro Islands off the east coast of Africa, and the Indonesian coelacanth (''Latimeria menadoensis''). The name "coelacanth" originates from the Permian genus ''Coelacanthus'', which was the first scientifically named coelacanth. Coelacanths follow the oldest-known living lineage of Sarcopterygii (lobe-finned fish and tetrapods), which means they are more closely related to lungfish and tetrapods (which includes amphibians, reptiles, birds and mammals) than to ray-finned fish. They are found along the coastline of Indonesia and in the Indian Ocean. The West Indian Ocean coelacanth is a critically endangered species. The oldest known coelacanth fossils are over 410 million years old. Coelacanths were thought to have become extinct in the Late Cretaceous, around 66 m ...

Wind Tunnel
Wind tunnels are large tubes with air blowing through them which are used to replicate the interaction between air and an object flying through the air or moving along the ground. Researchers use wind tunnels to learn more about how an aircraft will fly. NASA uses wind tunnels to test scale models of aircraft and spacecraft. Some wind tunnels are large enough to contain full-size versions of vehicles. The wind tunnel moves air around an object, making it seem as if the object is flying. Most of the time, large powerful fans suck air through the tube. The object being tested is held securely inside the tunnel so that it remains stationary. The object can be an aerodynamic test object such as a cylinder or an airfoil, an individual component, a small model of the vehicle, or a full-sized vehicle. The air moving around the stationary object shows what would happen if the object was moving through the air. The motion of the air can be studied in different ways; smoke or dye can be ...
