turkey


Turkey known officially as the Republic of Turkey (About this sound Türkiye Cumhuriyeti ), is a Eurasian country that stretches across the Anatolian peninsula in Western Asia and Thrace in the Balkan region of southeastern Europe. Turkey is bordered by eight countries: Bulgaria to the northwest; Greece to the west; Georgia to the northeast; Armenia, Azerbaijan (the exclave of Nakhchivan) and Iran to the east; and Iraq and Syria to the southeast. The Mediterranean Sea and Cyprus are to the south; the Aegean Sea to the west; and the Black Sea is to the north.

Separating Anatolia and Thrace are the Sea of Marmara and the Turkish Straits (the Bosphorus and the Dardanelles), which are commonly reckoned to delineate the boundary between Europe and Asia, thereby making Turkey a country of significant geostrategic importance. Ethnic Turks form the majority of the population, followed by the Kurds. The predominant religion in Turkey is Islam and its official language is Turkish.

Turkey is the successor state to the Ottoman Empire. It is a democratic, secular, unitary, constitutional republic, with an ancient and historical cultural heritage. Its political system was established in 1923 under the leadership of Mustafa Kemal Atatürk, following the fall of the Ottoman Empire in the aftermath of World War I. Since then, Turkey has become increasingly integrated with the West through membership in organizations such as the Council of Europe, NATO, OECD, OSCE and the G-20 major economies.

Turkey began full membership negotiations with the European Union in 2005, having been an associate member of the European Economic Community since 1963 and having reached a customs union agreement in 1995. Turkey has also fostered close cultural, political, economic and industrial relations with the Eastern world, particularly with the Middle East and the Turkic states of Central Asia, through membership in organizations such as the Organisation of the Islamic Conference and Economic Cooperation Organization. Turkey is classified as a developed country by the CIA and as a regional power by political scientists and economists worldwide.

The name of Turkey, Türkiye in the Turkish language, can be divided into two components: Türk, which means "strong" or "mighty" in Old Turkic[11] and usually signifying the inhabitants of Turkey or a member of the Turkish or Turkic peoples,[11] a later form of "Tu–kin", a name given by the Chinese to the people living south of the Altay Mountains of Central Asia as early as 177 BCE; and the abstract suffix –iye (derived from the Arabic suffix –iyya, but also associated with the Medieval Latin suffix –ia in Turchia.

The first recorded use of the term "Türk" or "Türük" as an autonym is contained in the Orkhon inscriptions of the Göktürks (Celestial Turks) of Central Asia (c. 8th century CE). The English word "Turkey" is derived from the Medieval Latin Turchia

amazon



The Amazon rainforest also known as Amazonia or Amazon jungle, is a moist broadleaf forest that covers most of the Amazon Basin of South America. This basin encompasses seven million square kilometers (1.7 billion acres), of which five and a half million square kilometers (1.4 billion acres) are covered by the rainforest. This region includes territory belonging to nine nations. The majority of the forest is contained within Brazil, with 60% of the rainforest, followed by Peru with 13%, and with minor amounts in Colombia, Venezuela, Ecuador, Bolivia, Guyana, Suriname and French Guiana. States or departments in four nations bear the name Amazonas after it. The Amazon represents over half of the planet's remaining rainforests, and it comprises the largest and most species-rich tract of tropical rainforest in the world. The Amazon rainforest was short-listed in 2008 as a candidate to one of the New7Wonders of Nature by the New Seven Wonders of the World Foundation. As of February 2009 the Amazon was ranking first in Group E, the category for forests, national parks and nature reserves
he name Amazon is said to arise from a war which Francisco de Orellana had with a tribe of Tapuyas and other tribes from South America. The women of the tribe fought alongside the men, as was the custom among the entire tribe.[2] Orellana's descriptions may have been accurate, but a few historians speculate that Orellana could have been mistaking indigenous men wearing "grass skirts" for women.[citation needed] Orellana derived the name Amazonas from the ancient Amazons of Asia and Africa described by Herodotus and Diodorus in Greek legends.[2]

Another etymology for the word suggests that it came originally from a native word amazona (Spanish spelling) or amassona (Portuguese spelling), meaning "destroyer (of) boats", in reference to the destructive nature of the root system possessed by some riparian plants.

river nile



The Nile (Arabic: النيل‎, an-nīl, Ancient Egyptian iteru or Ḥ'pī, Coptic piaro or phiaro) is a major north-flowing river in Africa, generally regarded as the longest river in the world.[1]

The Nile has two major tributaries, the White Nile and Blue Nile, the latter being the source of most of the Nile's water and fertile soil, but the former being the longer of the two. The White Nile rises in the Great Lakes region of central Africa, with the most distant source in southern Rwanda at 2°16′55.92″S 29°19′52.32″E / 2.2822°S 29.3312°E / -2.2822; 29.3312, and flows north from there through Tanzania, Lake Victoria, Uganda and southern Sudan, while the Blue Nile starts at Lake Tana in Ethiopia at 12°2′8.8″N 37°15′53.11″E / 12.035778°N 37.2647528°E / 12.035778; 37.2647528, flowing into Sudan from the southeast. The two rivers meet near the Sudanese capital of Khartoum.

The northern section of the river flows almost entirely through desert, from Sudan into Egypt, a country whose civilization has depended on the river since ancient times. Most of the population and cities of Egypt lie along those parts of the Nile valley north of Aswan, and nearly all the cultural and historical sites of Ancient Egypt are found along the banks of the river. The Nile ends in a large delta that empties into the Mediterranean Sea.

Tribe

A tribe, viewed historically or developmentally, consists of a social group existing before the development of, or outside of, states.

Many anthropologists use the term to refer to societies organized largely on the basis of kinship, especially corporate descent groups (see clan and kinship).

Some theorists hold that tribes represent a stage in social evolution intermediate between bands and states. Other theorists argue that tribes developed after, and must be understood in terms of their relationship to, states. Some criticize its connotations as a way of attaching "backwardness" and the racist notion of primitive since the term "tribe" is largely used to describe non-White peoples.

Etymology

The English word tribe occurs in 13th century Middle English literature as referring to one of the Twelve Tribes of Israel. The word is from Old French tribu, in turn from Latin tribus, referring to the original tripartite ethnic division of the Roman state: Tities (Titienses), Ramnes (Ramnenses), and Luceres, corresponding, according to Varro, to the Latins, Sabines, and Etruscans respectively. The Ramnes were named after Romulus, leader of the Latins, Tities after Tatius, leader of the Sabines, and Luceres after Lucumo, leader of an Etruscan army that had assisted the Latins. According to Livy, the three tribes were in fact squadrons of knights, rather than ethnic divisions.

The term's ultimate etymology may be found in the Latin word for three, "tres". The dative and ablative declensions of this word are both "tribus". The word "tribus" could therefore mean "from the three" or "for the three".

Another theory holds that tribus is perhaps derived from the PIE roots *tri- "three" and *bhew- "to be".[2]

From 242-240 BC, the Tribal Assembly (comitia tributa) in the Roman Republic was organized in 35 Tribes (4 "Urban Tribes" and 31 "Rural Tribes"). The Latin word as used in the Bible translates as Greek phyle "race, tribe, clan" and ultimately the Hebrew שבט (ʃe.væt) or "sceptre". In the historical sense, "tribe", "race" or "clan" can be used interchangeably.

[edit] Definition

Considerable debate takes place over how best to characterize tribes. Some of this debate stems from perceived differences between pre-state tribes and contemporary tribes; some of this debate reflects more general controversy over cultural evolution and colonialism. In the popular imagination, tribes reflect a way of life that predates, and is more "natural", than that in modern states. Tribes also privilege primordial social ties, are clearly bounded, homogeneous, parochial, and stable. Thus, many believed that tribes organize links between families (including clans and lineages), and provide them with a social and ideological basis for solidarity that is in some way more limited than that of an "ethnic group" or of a "nation". Anthropological and ethnohistorical research has challenged all of these notions.

Anthropologist Elman Service presented a system of classification for societies in all human cultures based on the evolution of social inequality and the role of the state. This system of classification contains four categories:

  1. Gatherer-hunter bands, which are generally egalitarian.
  2. Tribal societies in which there are some limited instances of social rank and prestige.
  3. Stratified tribal societies led by chieftains.
  4. Civilizations, with complex social hierarchies and organized, institutional governments.

In his 1972 study, The Notion of the Tribe, anthropologist Morton H. Fried provided numerous examples of tribes the members of which spoke different languages and practised different rituals, or that shared languages and rituals with members of other tribes. Similarly, he provided examples of tribes where people followed different political leaders, or followed the same leaders as members of other tribes. He concluded that tribes in general are characterized by fluid boundaries and heterogeneity, are not parochial, and are dynamic.[citation needed]

Fried, however, proposed that most contemporary tribes do not have their origin in pre-state tribes, but rather in pre-state bands. Such "secondary" tribes, he suggested, actually came about as modern products of state expansion. Bands comprise small, mobile, and fluid social formations with weak leadership, that do not generate surpluses, pay no taxes and support no standing army. Fried argued that secondary tribes develop in one of two ways. First, states could set them up as means to extend administrative and economic influence in their hinterland, where direct political control costs too much. States would encourage (or require) people on their frontiers to form more clearly bounded and centralized polities, because such polities could begin producing surpluses and taxes, and would have a leadership responsive to the needs of neighboring states (the so-called "scheduled" tribes of the United States or of British India provide good examples of this). Second, bands could form "secondary" tribes as a means to defend themselves against state expansion. Members of bands would form more clearly bounded and centralized polities, because such polities could begin producing surpluses that could support a standing army that could fight against states, and they would have a leadership that could co-ordinate economic production and military activities.

In some countries, such as the United States of America and India, tribes are polities that have been granted legal recognition and limited autonomy by the state.

Archeologists continue to explore the development of pre-state tribes. Current research suggests that tribal structures constituted one type of adaptation to situations providing plentiful yet unpredictable resources. Such structures proved flexible enough to co-ordinate production and distribution of food in times of scarcity, without limiting or constraining people during times of surplus.

Colosseum- one in 7 wonders of the world



The Colosseum or Roman Coliseum, originally the Flavian Amphitheatre (Latin: Amphitheatrum Flavium, Italian Anfiteatro Flavio or Colosseo), is an elliptical amphitheatre in the center of the city of Rome, Italy, the largest ever built in the Roman Empire. It is considered one of the greatest works of Roman architecture and Roman engineering.


Occupying a site just east of the Roman Forum, its construction started between 70 and 72 ADunder the emperor Vespasian and was completed in 80 AD under Titus, with further modifications being made during Domitian's reign (81–96). The name "Amphitheatrum Flavium" derives from both Vespasian's and Titus's family name (Flavius, from the gens Flavia).


Capable of seating 50,000 spectators,the Colosseum was used for gladiatorial contests and public spectacles. As well as the gladiatorial games, other public spectacles were held there, such as mock sea battles, animal hunts, executions, re-enactments of famous battles, and dramas based on Classical mythology. The building ceased to be used for entertainment in the early medieval era. It was later reused for such purposes as housing, workshops, quarters for a religious order, a fortress, a quarry, and a Christian shrine.


Although in the 21st century it stays partially ruined because of damage caused by devastating earthquakes and stone-robbers, the Colosseum is an iconic symbol of Imperial Rome and its breakthrough achievements in earthquake engineering. It is one of Rome's most popular tourist attractions and still has close connections with the Roman Catholic Church, as each Good Friday the Pope leads a torchlit "Way of the Cross" procession that starts in the area around the Colosseum.


The Colosseum is also depicted on the Italian version of the five-cent euro coin.

piranhas


piranhas live in South American rivers. In Venezuelan rivers, they are called caribes. They are known for their sharp teeth and a voracious appetite for meat
Question: Are Piranhas Dangerous?
Answer: A really hungry Piranha will bite most anything, even his own kin. However, Piranha normally feasts on other species of fish or wounded animals -- not humans. In fact, more piranhas are eaten by people then people are eaten by piranhas. Although I haven't had the pleasure of eating piranha myself, people in some areas of South America eat them regularly and say they are quite tasty.
How Dangerous Are They?
Fish expert, Dr. Axelrod, once stated on network television that piranhas are not dangerous to people. Later he was dared to prove it, and prove it he did. He waded into piranha infested waters wearing only swim trunks. Placing a large piece of meat on a fishhook, he dangled it in the water and waited to see what happened. The piranha tore into the meat but not Dr. Axelrod. Although I wouldn't recommend reaching in the tank to pet your piranha, as long as they are well fed they aren't likely to bite you.
Should You Keep Them?
Piranhas are not the most ideal aquarium fish. They can't be kept with other fish, because they would eat them. Unless your tank is bare, you won't see them out and about often, because they are rather skittish and hide a good deal of the time. Feeding time is when you will see the most action, and even then they may wait for you to leave the room before they feed.
If you are serious about wanting to keep piranha, study what they need to stay healthy. Piranhas are carnivores that prefer their food live. They need a quiet habitat with places to hide, and should not be kept with other fish, even their own species. Because of the danger they present to local habitats, piranhas are not legal in many states, so check your local laws before trying to bring one home.

the biggest pyramid in the world


The Great Pyramid of Giza (also called the Pyramid of Khufu and the Pyramid of Cheops) is the oldest and largest of the three pyramids in the Giza Necropolis bordering what is now El Giza, Egypt. It is the oldest of the Seven Wonders of the Ancient World, and the only one to remain largely intact. It is believed the pyramid was built as a tomb for fourth dynasty Egyptian Pharaoh Khufu (Cheops in Greek) and constructed over a 20-year period concluding around 2551 BC. The Great Pyramid was the tallest man-made structure in the world for over 3,800 years. Originally the Great Pyramid was covered by casing stones that formed a smooth outer surface; what is seen today is the underlying core structure. Some of the casing stones that once covered the structure can still be seen around the base. There have been varying scientific and alternative theories about the Great Pyramid's construction techniques. Most accepted construction hypotheses are based on the idea that it was built by moving huge stones from a quarry and dragging and lifting them into place.

There are three known chambers inside the Great Pyramid. The lowest chamber is cut into the bedrock upon which the pyramid was built and was unfinished. The so-called[1] Queen's Chamber and King's Chamber are higher up within the pyramid structure. The Great Pyramid of Giza is the main part of a complex setting of buildings that included two mortuary temples in honor of Khufu (one close to the pyramid and one near the Nile), three smaller pyramids for Khufu's wives, an even smaller "satellite" pyramid, a raised causeway connecting the two temples, and small mastaba tombs surrounding the pyramid for nobles.

desert sahara


People lived on the edge of the desert thousands of years ago since the last ice age. The Sahara was then a much wetter place than it is today. Over 30,000 petroglyphs of river animals such as crocodiles survive, with half found in the Tassili n'Ajjer in southeast Algeria. Fossils of dinosaurs, including Afrovenator, Jobaria and Ouranosaurus, have also been found here. The modern Sahara, though, is not lush in vegetation, except in the Nile Valley, at a few oases, and in the northern highlands, where Mediterranean plants such as the olive tree are found to grow. The region has been this way since about 5000 years ago. Some 2.5 million people currently live in the Sahara, most of these in Egypt, Mauritania, Morocco and Algeria. Dominant ethnicities in the Sahara are various Berber groups including Tuareg tribes, various Arabised Berber groups such as the Hassaniya-speaking Maure (Moors, also known as Sahrawis), and various black African ethnicities including Toubou, Nubians, Zaghawa, Kanuri, Peul (Fulani), Hausa and Songhai. Important cities located in the Sahara include Nouakchott (the capital of Mauritania), Tamanrasset, Ouargla, Bechar, Hassi Messaoud, Ghardaia, and El Oued (Algeria), Timbuktu (Mali), Agadez (Niger), Ghat (Libya), as well as Faya-Largeau
The Sahara has one of the harshest climates in the world. The prevailing north-easterly wind often causes the sand to form sand storms and dust devils.[18] Half of the Sahara receives less than 20 mm (0.79 in) of rain per year, and the rest receives up to 10 cm (3.9 in) per year.[19] The rainfall happens very rarely, but when it does it is usually torrential when it occurs after long dry periods, which can last for years.
