Asia
Asia is the world's largest and most populous continent. It covers 8.6% of the Earth's total surface area (or 29.9% of its land area) and, with over 4 billion people, it contains more than 60% of the world's current human population. Chiefly in the eastern and northern hemispheres, Asia is traditionally defined as part of the landmass of Eurasia—with the western portion of the latter occupied by Europe—lying east of the Suez Canal, east of the Ural Mountains, and south of the Caucasus Mountains and the Caspian and Black Seas. It is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. Given its size and diversity, Asia—a toponym dating back to classical antiquity—is more a cultural concept incorporating a number of regions and peoples than a homogeneous physical entity (see Subregions of Asia, Asian people).
Medieval Europeans considered Asia as a continent – a distinct landmass. The European concept of the three continents in the Old World goes back to Classical Antiquity, but during the Middle Ages was notably due to Isidore of Sevilla . The demarcation between Asia and Africa (to the southwest) is the Isthmus of Suez and the Red Sea. The boundary between Asia and Europe is conventionally considered to run through the Dardanelles, the Sea of Marmara, the Bosporus, the Black Sea, the Caucasus Mountains, the Caspian Sea, the Ural River to its source, and the Ural Mountains to the Kara Sea near Kara, Russia. While this interpretation of tripartite continents (i.e., of Asia, Europe, and Africa) remains common in modernity, discovery of the extent of Africa and Asia have made this definition somewhat anachronistic. This is especially true in the case of Asia, which would have several regions that would be considered distinct landmasses if these criteria were used (for example, Southern Asia and Eastern Asia).
In the far northeast of Asia, Siberia is separated from North America by the Bering Strait. Asia is bounded on the south by the Indian Ocean (specifically, from west to east, the Gulf of Aden, Arabian Sea, and Bay of Bengal); on the east by the waters of the Pacific Ocean (including, counterclockwise, the South China Sea, East China Sea, Yellow Sea, Sea of Japan, Sea of Okhotsk, and Bering Sea); and on the north by the Arctic Ocean. Australia (or Oceania) is to the southeast.
Some geographers do not consider Asia and Europe to be separate continents,[5] as there is no logical physical separation between them.[3] For example, Sir Barry Cunliffe, the emeritus professor of European archeology at Oxford, argue that Europe has been geographically and culturally merely “the western excrescence of the continent of Asia.” Geographically, Asia is the major eastern constituent of the continent of Eurasia – with Europe being a northwestern peninsula of the landmass – or of Afro-Eurasia: geologically, Asia, Europe, and Africa comprise a single continuous landmass (save the Suez Canal) and share a common continental shelf. Almost all of Europe and most of Asia sit atop the Eurasian Plate, adjoined on the south by the Arabian and Indian Plates, and with the easternmost part of Siberia (east of the Cherskiy Range) on the North American Plate.
In geography, there are two schools of thought. One school follows historical convention and treats Europe and Asia as different continents, categorizing subregions within them for more detailed analysis. The other school equates the word "continent" with a geographical region when referring to Europe, and use the term "region" to describe Asia in terms of physiography. Since, in linguistic terms, "continent" implies a distinct landmass, it is becoming increasingly common to substitute the term "region" for "continent" to avoid the problem of disambiguation altogether.
Given the scope and diversity of the landmass, it is sometimes not even clear exactly what "Asia" consists of. Some definitions exclude Turkey, the Middle East, Central Asia, and Russia while only considering the Far East, Southeast Asia and the Indian subcontinent to compose Asia, especially in the United States after World War II. The term is sometimes used more strictly in reference to the Asia-Pacific region, which does not include the Middle East or Russia, but does include islands in the Pacific Ocean—a number of which may also be considered part of Australasia or Oceania, although Pacific Islanders are commonly not considered Asian.
The history of Asia can be seen as the distinct histories of several peripheral coastal regions: East Asia, South Asia, Southeast Asia and the Middle East, linked by the interior mass of the Central Asian steppes.
The coastal periphery was home to some of the world's earliest known civilizations, each of them developing around fertile river valleys. The civilizations in Mesopotamia, the Indus Valley, and the Huanghe shared many similarities. These civilizations may well have exchanged technologies and ideas such as mathematics and the wheel. Other innovations, such as writing, seem to have been developed individually in each area. Cities, states, and empires developed in these lowlands.
The central steppe region had long been inhabited by horse-mounted nomads who could reach all areas of Asia from the steppes. The earliest postulated expansion out of the steppe is that of the Indo-Europeans, who spread their languages into the Middle East, South Asia, and the borders of China, where the Tocharians resided. The northernmost part of Asia, including much of Siberia, was largely inaccessible to the steppe nomads, owing to the dense forests, climate, and tundra. These areas remained very sparsely populated.
The center and the peripheries were mostly kept separated by mountains and deserts. The Caucasus and Himalaya mountains and the Karakum and Gobi deserts formed barriers that the steppe horsemen could cross only with difficulty. While the urban city dwellers were more advanced technologically and socially, in many cases they could do little in a military aspect to defend against the mounted hordes of the steppe. However, the lowlands did not have enough open grasslands to support a large horsebound force; for this and other reasons, the nomads who conquered states in China, India, and the Middle East often found themselves adapting to the local, more affluent societies.
Asia has the third largest nominal GDP of all continents, after North America and Europe, but the largest when measured in PPP. As of 2007, the largest national economy within Asia, in terms of gross domestic product (GDP), is that of China followed by that of India, Japan, South Korea and Indonesia. However, in nominal (exchange value) terms, they rank as follows: Japan, China, India, South Korea, Saudi Arabia, Taiwan, Indonesia. Since the 1960s, South Korea had maintained the highest economic growth rate in Asia, nicknamed as an Asian tiger, becoming a newly industrialized country in the 1980s and a developed country by the 21st century. In the late 1990s and early 2000s, the economies of the PRC[34] and India have been growing rapidly, both with an average annual growth rate of more than 8%. Other recent very high growth nations in Asia include the Philippines, Pakistan, Vietnam, Mongolia, Uzbekistan and mineral-rich nations such as Kazakhstan, Turkmenistan, Iran, Brunei, United Arab Emirates, Qatar, Kuwait, Saudi Arabia, Bahrain, and Oman.
Historically, Japan has had the largest economy in Asia and second-largest of any single nation in the world, after surpassing the Soviet Union (measured in net material product) in 1986 and Germany in 1968. (NB: A number of supernational economies are larger, such as the European Union (EU), the North American Free Trade Agreement (NAFTA) or APEC). In the late 1980s and early 1990s, Japan's GDP was almost as large (current exchange rate method) as that of the rest of Asia combined. In 1995, Japan's economy nearly equalled that of the USA to tie as the largest economy in the world for a day, after the Japanese currency reached a record high of 79 yen/dollar. Economic growth in Asia since World War II to the 1990s had been concentrated in the four regions of South Korea, Taiwan, Hong Kong and Singapore located in the pacific rim, known as the Asian tigers, which have now all received developed country status, having the highest GDP per capita in Asia.
It is forecast that the People's Republic of China will surpass Japan to have the largest nominal and PPP-adjusted GDP in Asia within a decade. India is also forecast to overtake Japan in terms of Nominal GDP by 2020. In terms of GDP per capita, both nominal and PPP-adjusted, South Korea will become the second wealthiest country in Asia by 2025, overtaking Germany, the United Kingdom and France. By 2050, according to a 2006 report by Price Waterhouse Cooper, China will have the largest economy in the world (43% greater than the United States when PPP adjusted, although perhaps smaller than the United States in nominal terms).

Jacques-Nicolas Bellin
Jacques-Nicolas Bellin was born in the year of 1703 in Paris and died on 21st of March in the year of 1772. He was assigned as a chief cartographer to the French Navy in the year of 1721. Bellin had worked for the Depot des Cartes et Plans de la Marine. He had spent 50 years of his career in created maps, which made him one of the brilliant Map Makers of Modern Era. Some of the great Works of Jacques-Nicolas Bellin are the maps of Canada and of French territories in North America.
Jacques-Nicolas Bellin had some of his works published during his lifetime. These were Hydrographie Française in 1753, Petit Atlas Maritime in 1764 and Nouvelle methode pour apprendre la geographie in 1769. The last creation out of these few had five volumes and several hundreds of maps. Among the other works of Jacques-Nicolas Bellin, maps of l'Abbe Prevost's Histoire Generale des Voyages are worth mentioning. Apart from these, Bellin also made many accurate and finely engraved maps, which were separately issued. All his creations were detailed work based on valued researches.
