Europe

Europe (ⁱ/ˈjʊərəp/ ewr-əp or /ˈjɜrəp/ yur-əp^[1]) is, by convention, one of the world's seven continents. Comprising the westernmost peninsula of Eurasia, Europe is generally 'divided' from Asia by the watershed divides of the Ural and CaucasusMountains, the Ural River, the Caspian and Black Seas, and the waterways connecting the Black and Aegean Seas.^[2] Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south, and the Black Sea and connected waterways to the southeast. Yet the borders of Europe—a concept dating back to classical antiquity—are somewhat arbitrary, as the primarily physiographic term "continent" can incorporate cultural and political elements.

Europe is the world's second-smallest continent by surface area, covering about 10,180,000 square kilometres (3,930,000 sq mi) or 2% of the Earth's surface and about 6.8% of its land area. Of Europe's approximately 50 states, Russia is by far the largest by both area and population, taking up 40% of the continent (although the country has territory in both Europe and Asia), while the Vatican City is the smallest. Europe is the third-most populous continent after Asia and Africa, with a population of 733 million or about 11% of the world's population.^[3]

Europe, in particular Ancient Greece, is the birthplace of Western culture.^[4] It played a predominant role in global affairs from the 15th century onwards, especially after the beginning of colonialism. Between the 16th and 20th centuries, European nations controlled at various times the Americas, most of Africa, Oceania, and large portions of Asia. Both World Wars were largely focused upon Europe, greatly contributing to a decline in Western European dominance in world affairs by the mid-20th century as the United States and Soviet Union took prominence.^[5] During the Cold War, Europe was divided along the Iron Curtain between NATO in the west and the Warsaw Pact in the east. European integration led to the formation of the Council of Europe and the European Union in Western Europe, both of which have been expanding eastward since the fall of the Soviet Union in 1991.

Definition

The use of the term "Europe" has developed gradually throughout history.^[6][7] In antiquity, the Greek historian Herodotus mentioned that the world had been divided by unknown persons into three parts, Europe, Asia, and Libya (Africa), with the Nile and the River Phasis forming their boundaries—though he also states that some considered the River Don, rather than the Phasis, as the boundary between Europe and Asia.^[8] Europe's eastern frontier was defined in the 1st century by geographer Strabo at the River Don.^[9] Flavius and the Book of Jubilees described the continents as the lands given by Noah to his three sons; Europe was defined as stretching from the Pillars of Hercules at the Strait of Gibraltar, separating it from North Africa, to the Don, separating it from Asia.^[10]

A cultural definition of Europe as the lands of Latin Christendom coalesced in the 8th century, signifying the new cultural condominium created through the confluence of Germanic traditions and Christian-Latin culture, defined partly in contrast with Byzantium and Islam, and limited to northern Iberia, the British Isles, France, Christianized western Germany, the Alpine regions and northern and central Italy.^[11] The concept is one of the lasting legacies of the Carolingian Renaissance: "Europa" often figures in the letters of Charlemagne's cultural minister,Alcuin.^[12] This division—as much cultural as geographical—was used until the Late Middle Ages, when it was challenged by the Age of Discovery.^{[13][14][why?]} The problem of redefining Europe was finally resolved in 1730 when, instead of waterways, the Swedish geographer and cartographer von Strahlenberg proposed the Ural Mountains as the most significant eastern boundary, a suggestion that found favour in Russia and throughout Europe.^[15]

Europe is now generally defined by geographers as the westernmost peninsula of Eurasia, with its boundaries marked by large bodies of water to the north, west and south; Europe's limits to the far east are usually taken to be the Urals, the Ural River, and the Caspian Sea; to the south-east, including the Caucasus Mountains, the Black Sea and the waterways connecting the Black Sea to the Mediterranean Sea.^[16] Because of sociopolitical and cultural differences, there are various descriptions of Europe's boundary. For example, Cyprus is approximate to Anatolia (or Asia Minor), but is usually considered part of Europe and currently is a member state of the EU. In addition, Malta was considered an island of North Africa for centuries,^[17] while Iceland, though nearer to Greenland (North America), is also generally included in Europe.

Sometimes, the word 'Europe' is used in a geopolitically limiting way^[18] to refer only to the European Union or, even more exclusively, a culturally defined core. On the other hand, the Council of Europe has 47 member countries, and only 27 member states are in the EU.^[19] In addition, people living in insular areas such as Ireland, the United Kingdom, the North Atlantic and Mediterranean islands and also in Scandinavia may routinely refer to"continental" or "mainland" Europe simply as Europe or "the Continent".

Animation

Animation is the rapid display of a sequence of images to create an illusion of movement. The most common method of presenting animation is as a motion picture or video program, although there are other methods. This type of presentation is usually accomplished with a camera and a projector or a computer viewing screen which can rapidly cycle through images in a sequence. Animation can be made with either hand rendered art, computer generated imagery, or three-dimensional objects, e.g. puppets or clay figures, or a combination of techniques. The position of each object in any particular image relates to the position of that object in the previous and following images so that the objects each appear to fluidly move independently of one another. The viewing device displays these images in rapid succession, usually 24, 25 or 30 frames per second.

History

Early examples of attempts to capture the phenomenon of motion drawing can be found in paleolithic cave paintings, where animals are depicted with multiple legs in superimposed positions, clearly attempting to convey the perception of motion.

A 5,000 year old earthen bowl found in Iran in Shahr-i Sokhta has five images of a goat painted along the sides. This has been claimed to be an example of early animation. However, since no equipment existed to show the images in motion, such a series of images cannot be called animation in a true sense of the word.^[1]

A Chinese zoetrope-type device had been invented in 180 AD.^[2] The phenakistoscope, praxinoscope, and the common flip book were early popular animation devices invented during the 19th century.

These devices produced the appearance of movement from sequential drawings using technological means, but animation did not really develop much further until the advent of cinematography.

There is no single person who can be considered the "creator" of film animation, as there were several people working on projects which could be considered animation at about the same time.

Georges Méliès was a creator of special-effect films; he was generally one of the first people to use animation with his technique. He discovered a technique by accident which was to stop the camera rolling to change something in the scene, and then continue rolling the film. This idea was later known as stop-motion animation. Méliès discovered this technique accidentally when his camera broke down while shooting a bus driving by. When he had fixed the camera, a hearse happened to be passing by just as Méliès restarted rolling the film, his end result was that he had managed to make a bus transform into a hearse. This was just one of the great contributors to animation in the early years.

The earliest surviving stop-motion advertising film was an English short by Arthur Melbourne-Cooper called Matches: An Appeal (1899). Developed for the Bryant and May Matchsticks company, it involved stop-motion animation of wired-together matches writing a patriotic call to action on a blackboard.

J. Stuart Blackton was possibly the first American film-maker to use the techniques of stop-motion and hand-drawn animation. Introduced to film-making by Edison, he pioneered these concepts at the turn of the 20th century, with his first copyrighted work dated 1900. Several of his films, among them The Enchanted Drawing (1900) and Humorous Phases of Funny Faces (1906) were film versions of Blackton's "lightning artist" routine, and utilized modified versions of Méliès' early stop-motion techniques to make a series of blackboard drawings appear to move and reshape themselves. 'Humorous Phases of Funny Faces' is regularly cited as the first true animated film, and Blackton is considered the first true animator.

Fantasmagorie by Emile Cohl, 1908

Another French artist, Émile Cohl, began drawing cartoon strips and created a film in 1908 called Fantasmagorie. The film largely consisted of a stick figure moving about and encountering all manner of morphing objects, such as a wine bottle that transforms into a flower. There were also sections of live action where the animator’s hands would enter the scene. The film was created by drawing each frame on paper and then shooting each frame onto negative film, which gave the picture a blackboard look. This makes Fantasmagorie the first animated film created using what came to be known as traditional (hand-drawn) animation.

Following the successes of Blackton and Cohl, many other artists began experimenting with animation. One such artist wasWinsor McCay, a successful newspaper cartoonist, who created detailed animations that required a team of artists and painstaking attention for detail. Each frame was drawn on paper; which invariably required backgrounds and characters to be redrawn and animated. Among McCay's most noted films are Little Nemo (1911), Gertie the Dinosaur (1914) and The Sinking of the Lusitania (1918).

The production of animated short films, typically referred to as "cartoons", became an industry of its own during the 1910s, and cartoon shorts were produced to be shown in movie theaters. The most successful early animation producer was John Randolph Bray, who, along with animator Earl Hurd, patented the cel animation process which dominated the animation industry for the rest of the decade.

El Apóstol (Spanish: "The Apostle") was a 1917 Argentine animated film utilizing cutout animation, and the world's first animated feature film.^[3]

Computer animation has become popular since Toy Story (1995), the first animated film completely made using this technique.

In 2008, the animation market was worth US$68.4 billion.

Cartoon

A cartoon is a form of two-dimensional illustrated visual art. While the specific definition has changed over time, modern usage refers to a typically non-realistic or semi-realistic drawing or painting intended for satire, caricature, or humor, or to the artistic style of such works. An artist who creates cartoons is called a cartoonist.^[1]

The term originated in the Middle Ages and first described a preparatory drawing for a piece of art, such as a painting,fresco, tapestry, or stained glass window. In the 19th century, it came to refer to humorous illustrations in magazines and newspapers, and in the early 20th century and onward it referred to comic strips and animated films.

Fine art

A cartoon (from the Italian "cartone" and Dutch word "karton", meaning strong, heavy paper or pasteboard) is a full-size drawing made on sturdy paper as a study or modello for a painting, stained glass or tapestry. Cartoons were typically used in the production of frescoes, to accurately link the component parts of the composition when painted on damp plaster over a series of days (giornate).

Such cartoons often have pinpricks along the outlines of the design; a bag of soot was then patted or "pounced" over the cartoon, held against the wall to leave black dots on the plaster ("pouncing"). Cartoons by painters, such as the Raphael Cartoons in London and examples by Leonardo da Vinci, are highly prized in their own right. Tapestry cartoons, usually coloured, were followed by eye by the weavers on the loom.

Print media

In modern print media, a cartoon is a piece of art, usually humorous in intent. This usage dates from 1843 when Punch magazine applied the term to satirical drawings in its pages,^[3] particularly sketches by John Leech. The first of these parodied the preparatory cartoons for grand historical frescoes in the then-new Palace of Westminster. The original title for these drawings was Mr Punch's face is the letter Q and the new title "cartoon" was intended to be ironic, a reference to the self-aggrandizing posturing of Westminster politicians.

Modern single-panel gag cartoons, found in magazines, generally consist of a single drawing with a typeset caption positioned beneath or (much less often) a speech balloon. Newspaper syndicates have also distributed single-panel gag cartoons by Mel Calman, Bill Holman, Gary Larson, George Lichty, Fred Neher and others. Many consider New Yorker cartoonist Peter Arno the father of the modern gag cartoon (as did Arno himself). The roster of magazine gag cartoonists includes Charles Addams, Charles Barsottiand Chon Day.

Bill Hoest, Jerry Marcus and Virgil Partch began as a magazine gag cartoonists and moved on to do syndicated comic strips. Noteworthy in the area of newspaper cartoon illustration is Richard Thompson, who illustrated numerous feature articles in The Washington Post before creating his Cul de Sac comic strip. Sports sections of newspapers usually featured cartoons, sometimes including syndicated features such as Chester "Chet" Brown's All in Sport.

Editorial cartoons are found almost exclusively in news publications and news websites. Although they also employ humor, they are more serious in tone, commonly using irony or satire. The art usually acts as a visual metaphor to illustrate a point of view on current social and/or political topics. Editorial cartoons often include speech balloons and, sometimes, multiple panels. Editorial cartoonists of note include Herblock, David Low, Jeff MacNelly, Mike Peters and Gerald Scarfe.^[2]

Comic strips, also known as "cartoon strips" in the United Kingdom, are found daily in newspapers worldwide, and are usually a short series of cartoon illustrations in sequence. In the United States they are not as commonly called "cartoons" themselves, but rather "comics" or "funnies". Nonetheless, the creators of comic strips—as well as comic books andgraphic novels—are usually referred to as "cartoonists". Although humor is the most prevalent subject matter, adventure and drama are also represented in this medium. Noteworthy cartoonists of humor strips include Scott Adams, Steve Bell, Charles Schulz, E. C. Segar, Mort Walker and Bill Watterson.

Internet

The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (often called TCP/IP, although not all applications use TCP) to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertextdocuments of the World Wide Web (WWW) and the infrastructure to support email.

Most traditional communications media including telephone, music, film, and television are reshaped or redefined by the Internet, giving birth to new services such as Voice over Internet Protocol (VoIP) and Internet Protocol Television (IPTV). Newspaper, book and other print publishing are adapting to Web site technology, or are reshaped into blogging and web feeds. The Internet has enabled and accelerated new forms of human interactions through instant messaging, Internet forums, and social networking. Online shopping has boomed both for major retail outlets and small artisans and traders. Business-to-business and financial services on the Internet affect supply chains across entire industries.

The origins of the Internet reach back to research of the 1960s, commissioned by the United States government in collaboration with private commercial interests to build robust, fault-tolerant, and distributed computer networks. The funding of a new U.S. backbone by the National Science Foundation in the 1980s, as well as private funding for other commercial backbones, led to worldwide participation in the development of new networking technologies, and the merger of many networks. The commercialization of what was by the 1990s an international network resulted in its popularization and incorporation into virtually every aspect of modern human life. As of 2011, more than 2.2 billion people – nearly a third of Earth's population — use the services of the Internet.^[1]

The Internet has no centralized governance in either technological implementation or policies for access and usage; each constituent network sets its own standards. Only the overreaching definitions of the two principal name spaces in the Internet, the Internet Protocol address space and the Domain Name System, are directed by a maintainer organization, the Internet Corporation for Assigned Names and Numbers (ICANN). The technical underpinning and standardization of the core protocols (IPv4 and IPv6) is an activity of the Internet Engineering Task Force (IETF), a non-profit organization of loosely affiliated international participants that anyone may associate with by contributing technical expertise.

blood

Blood is a specialized bodily fluid in animals that delivers necessary substances such as nutrients and oxygen to the cellsand transports metabolic waste products away from those same cells.

In vertebrates, it is composed of blood cells suspended in a liquid called blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume),^[1] and contains dissipated proteins, glucose, mineral ions, hormones, carbon dioxide (plasma being the main medium for excretory product transportation), and blood cells themselves. Albumin is the main protein in plasma, and it functions to regulate the colloidal osmotic pressure of blood. The blood cells are mainly red blood cells (also called RBCs or erythrocytes) and white blood cells, including leukocytes and platelets. The most abundant cells in vertebrate blood are red blood cells. These contain hemoglobin, an iron-containing protein, which facilitates transportation of oxygen by reversibly binding to this respiratory gas and greatly increasing its solubility in blood. In contrast, carbon dioxide is almost entirely transported extracellularly dissolved in plasma as bicarbonate ion.

Vertebrate blood is bright red when its hemoglobin is oxygenated. Some animals, such as crustaceans and mollusks, usehemocyanin to carry oxygen, instead of hemoglobin. Insects and some mollusks use a fluid called hemolymph instead of blood, the difference being that hemolymph is not contained in a closed circulatory system. In most insects, this "blood" does not contain oxygen-carrying molecules such as hemoglobin because their bodies are small enough for their tracheal system to suffice for supplying oxygen.

Jawed vertebrates have an adaptive immune system, based largely on white blood cells. White blood cells help to resist infections and parasites. Platelets are important in the clotting of blood.^[2] Arthropods, using hemolymph, have hemocytes as part of their immune system.

Blood is circulated around the body through blood vessels by the pumping action of the heart. In animals with lungs, arterial blood carries oxygen from inhaled air to the tissues of the body, and venous blood carries carbon dioxide, a waste product of metabolism produced bycells, from the tissues to the lungs to be exhaled.

Medical terms related to blood often begin with hemo- or hemato- (also spelled haemo- and haemato-) from the Greek word αἷμα(haima) for "blood". In terms of anatomy and histology, blood is considered a specialized form of connective tissue, given its origin in the bones and the presence of potential molecular fibers in the form of fibrinogen.
