Lebanon known as the Lebanese Republic, is a country in Western Asia. It is bordered by Syria to the north and east and Israel to the south, while Cyprus is west across the Mediterranean Sea. Lebanon's location at the crossroads of the Mediterranean Basin and the Arabian hinterland facilitated its rich history and shaped a cultural identity of religious and ethnic diversity. At just 10,452 km2, it is the smallest recognized sovereign state on the mainland Asian continent; the earliest evidence of civilization in Lebanon dates back more than seven thousand years, predating recorded history. Lebanon was the home of the Canaanites/Phoenicians and their kingdoms, a maritime culture that flourished for over a thousand years. In 64 BC, the region came under the rule of the Roman Empire, became one of the Empire's leading centers of Christianity. In the Mount Lebanon range a monastic tradition known as the Maronite Church was established; as the Arab Muslims conquered the region, the Maronites held onto their identity.
However, a new religious group, the Druze, established themselves in Mount Lebanon as well, generating a religious divide that has lasted for centuries. During the Crusades, the Maronites re-established contact with the Roman Catholic Church and asserted their communion with Rome; the ties they established with the Latins have influenced the region into the modern era. The region was ruled by the Ottoman Empire from 1516 to 1918. Following the collapse of the empire after World War I, the five provinces that constitute modern Lebanon came under the French Mandate of Lebanon; the French expanded the borders of the Mount Lebanon Governorate, populated by Maronites and Druze, to include more Muslims. Lebanon gained independence in 1943, establishing confessionalism, a unique, Consociationalism-type of political system with a power-sharing mechanism based on religious communities. Bechara El Khoury, President of Lebanon during the independence, Riad El-Solh, first Lebanese prime minister and Emir Majid Arslan II, first Lebanese minister of defence, are considered the founders of the modern Republic of Lebanon and are national heroes for having led the country's independence.
Foreign troops withdrew from Lebanon on 31 December 1946, although the country was subjected to military occupations by Syria that lasted nearly thirty years before being withdrawn in April 2005 as well as the Israeli military in Southern Lebanon for fifteen years. Despite its small size, the country has developed a well-known culture and has been influential in the Arab world, powered by its large diaspora. Before the Lebanese Civil War, the country experienced a period of relative calm and renowned prosperity, driven by tourism, agriculture and banking; because of its financial power and diversity in its heyday, Lebanon was referred to as the "Switzerland of the East" during the 1960s, its capital, attracted so many tourists that it was known as "the Paris of the Middle East". At the end of the war, there were extensive efforts to revive the economy and rebuild national infrastructure. In spite of these troubles, Lebanon has the 7th highest Human Development Index and GDP per capita in the Arab world after the oil-rich economies of the Persian Gulf.
Lebanon has been a member of the United Nations since its founding in 1945 as well as of the Arab League, the Non-Aligned Movement, Organisation of the Islamic Cooperation and the Organisation internationale de la francophonie. The name of Mount Lebanon originates from the Phoenician root lbn meaning "white" from its snow-capped peaks. Occurrences of the name have been found in different Middle Bronze Age texts from the library of Ebla, three of the twelve tablets of the Epic of Gilgamesh; the name is recorded in Ancient Egyptian as Rmnn, where R stood for Canaanite L. The name occurs nearly 70 times in the Hebrew Bible, as לְבָנוֹן. Lebanon as the name of an administrative unit was introduced with the Ottoman reforms of 1861, as the Mount Lebanon Mutasarrifate, continued in the name of the State of Greater Lebanon in 1920, in the name of the sovereign Republic of Lebanon upon its independence in 1943; the borders of contemporary Lebanon are a product of the Treaty of Sèvres of 1920. Its territory was the core of the Bronze Age Phoenician city-states.
As part of the Levant, it was part of numerous succeeding empires throughout ancient history, including the Egyptian, Babylonian, Achaemenid Persian, Hellenistic and Sasanid Persian empires. After the 7th-century Muslim conquest of the Levant, it was part of the Rashidun, Abbasid Seljuk and Fatimid empires; the crusader state of the County of Tripoli, founded by Raymond IV of Toulouse in 1102, encompassed most of present-day Lebanon, falling to the Mamluk Sultanate in 1289 and to the Ottoman Empire in 1517. With the dissolution of the Ottoman Empire, Greater Lebanon fell under French mandate in 1920, gained independence under president Bechara El Khoury in 1943. Lebanon's history since independence has been marked by alternating periods of political stability and prosperity based on Beirut's position as a regional center for finance and trade, interspersed with political turmoil and
An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system. These biotic and abiotic components are linked together through nutrient cycles and energy flows. Energy is incorporated into plant tissue. By feeding on plants and on one-another, animals play an important role in the movement of matter and energy through the system, they influence the quantity of plant and microbial biomass present. By breaking down dead organic matter, decomposers release carbon back to the atmosphere and facilitate nutrient cycling by converting nutrients stored in dead biomass back to a form that can be used by plants and other microbes. Ecosystems are controlled by internal factors. External factors such as climate, the parent material which forms the soil and topography, control the overall structure of an ecosystem, but are not themselves influenced by the ecosystem. Ecosystems are dynamic entities—they are subject to periodic disturbances and are in the process of recovering from some past disturbance.
Ecosystems in similar environments that are located in different parts of the world can end up doing things differently because they have different pools of species present. Internal factors not only control ecosystem processes but are controlled by them and are subject to feedback loops. Resource inputs are controlled by external processes like climate and parent material. Resource availability within the ecosystem is controlled by internal factors like decomposition, root competition or shading. Although humans operate within ecosystems, their cumulative effects are large enough to influence external factors like climate. Biodiversity affects ecosystem functioning, as do the processes of disturbance and succession. Ecosystems provide a variety of services upon which people depend; the term ecosystem was first used in 1935 in a publication by British ecologist Arthur Tansley. Tansley devised the concept to draw attention to the importance of transfers of materials between organisms and their environment.
He refined the term, describing it as "The whole system... including not only the organism-complex, but the whole complex of physical factors forming what we call the environment". Tansley regarded ecosystems not as natural units, but as "mental isolates". Tansley defined the spatial extent of ecosystems using the term ecotope. G. Evelyn Hutchinson, a limnologist, a contemporary of Tansley's, combined Charles Elton's ideas about trophic ecology with those of Russian geochemist Vladimir Vernadsky; as a result, he suggested. This would, in turn, limit the abundance of animals. Raymond Lindeman took these ideas further to suggest that the flow of energy through a lake was the primary driver of the ecosystem. Hutchinson's students, brothers Howard T. Odum and Eugene P. Odum, further developed a "systems approach" to the study of ecosystems; this allowed them to study the flow of material through ecological systems. Ecosystems are controlled both by internal factors. External factors called state factors, control the overall structure of an ecosystem and the way things work within it, but are not themselves influenced by the ecosystem.
The most important of these is climate. Climate determines the biome. Rainfall patterns and seasonal temperatures influence photosynthesis and thereby determine the amount of water and energy available to the ecosystem. Parent material determines the nature of the soil in an ecosystem, influences the supply of mineral nutrients. Topography controls ecosystem processes by affecting things like microclimate, soil development and the movement of water through a system. For example, ecosystems can be quite different if situated in a small depression on the landscape, versus one present on an adjacent steep hillside. Other external factors that play an important role in ecosystem functioning include time and potential biota; the set of organisms that can be present in an area can significantly affect ecosystems. Ecosystems in similar environments that are located in different parts of the world can end up doing things differently because they have different pools of species present; the introduction of non-native species can cause substantial shifts in ecosystem function.
Unlike external factors, internal factors in ecosystems not only control ecosystem processes but are controlled by them. They are subject to feedback loops. While the resource inputs are controlled by external processes like climate and parent material, the availability of these resources within the ecosystem is controlled by internal factors like decomposition, root competition or shading. Other factors like disturbance, succession or the types of species present are internal factors. Primary production is the production of organic matter from inorganic carbon sources; this occurs through photosynthesis. The energy incorporated through this process supports life on earth, while the carbon makes up much of the organic matter in living and dead biomass, soil carbon and fossil fuels, it drives the carbon cycle, which influences global climate via the greenhouse effect. Through the process of photosynthesis, plants capture energy from light and use it to combine carbon dioxide and water to produce carbohydrates and oxygen.
The photosynthesis carried out by all the plants in an ecosystem is called the gross primary production. About half of the GPP is consumed in plant respiration; the remainder, that portion of GPP, not used up by respirati
Romania is a country located at the crossroads of Central and Southeastern Europe. It borders the Black Sea to the southeast, Bulgaria to the south, Ukraine to the north, Hungary to the west, Serbia to the southwest, Moldova to the east, it has a predominantly temperate-continental climate. With a total area of 238,397 square kilometres, Romania is the 12th largest country and the 7th most populous member state of the European Union, having 20 million inhabitants, its capital and largest city is Bucharest, other major urban areas include Cluj-Napoca, Timișoara, Iași, Constanța, Brașov. The River Danube, Europe's second-longest river, rises in Germany's Black Forest and flows in a general southeast direction for 2,857 km, coursing through ten countries before emptying into Romania's Danube Delta; the Carpathian Mountains, which cross Romania from the north to the southwest, include Moldoveanu Peak, at an altitude of 2,544 m. Modern Romania was formed in 1859 through a personal union of the Danubian Principalities of Moldavia and Wallachia.
The new state named Romania since 1866, gained independence from the Ottoman Empire in 1877. Following World War I, when Romania fought on the side of the Allied powers, Bessarabia, Transylvania as well as parts of Banat, Crișana, Maramureș became part of the sovereign Kingdom of Romania. In June–August 1940, as a consequence of the Molotov–Ribbentrop Pact and Second Vienna Award, Romania was compelled to cede Bessarabia and Northern Bukovina to the Soviet Union, Northern Transylvania to Hungary. In November 1940, Romania signed the Tripartite Pact and in June 1941 entered World War II on the Axis side, fighting against the Soviet Union until August 1944, when it joined the Allies and recovered Northern Transylvania. Following the war, under the occupation of the Red Army's forces, Romania became a socialist republic and member of the Warsaw Pact. After the 1989 Revolution, Romania began a transition back towards a market economy; the sovereign state of Romania is a developing country and ranks 52nd in the Human Development Index.
It has the world's 47th largest economy by nominal GDP and an annual economic growth rate of 7%, the highest in the EU at the time. Following rapid economic growth in the early 2000s, Romania has an economy predominantly based on services, is a producer and net exporter of machines and electric energy, featuring companies like Automobile Dacia and OMV Petrom, it has been a member of the United Nations since 1955, part of NATO since 2004, part of the European Union since 2007. An overwhelming majority of the population identifies themselves as Eastern Orthodox Christians and are native speakers of Romanian, a Romance language. Romania derives from the Latin romanus, meaning "citizen of Rome"; the first known use of the appellation was attested to in the 16th century by Italian humanists travelling in Transylvania and Wallachia. The oldest known surviving document written in Romanian, a 1521 letter known as the "Letter of Neacșu from Câmpulung", is notable for including the first documented occurrence of the country's name: Wallachia is mentioned as Țeara Rumânească.
Two spelling forms: român and rumân were used interchangeably until sociolinguistic developments in the late 17th century led to semantic differentiation of the two forms: rumân came to mean "bondsman", while român retained the original ethnolinguistic meaning. After the abolition of serfdom in 1746, the word rumân fell out of use and the spelling stabilised to the form român. Tudor Vladimirescu, a revolutionary leader of the early 19th century, used the term Rumânia to refer to the principality of Wallachia."The use of the name Romania to refer to the common homeland of all Romanians—its modern-day meaning—was first documented in the early 19th century. The name has been in use since 11 December 1861. In English, the name of the country was spelt Rumania or Roumania. Romania became the predominant spelling around 1975. Romania is the official English-language spelling used by the Romanian government. A handful of other languages have switched to "o" like English, but most languages continue to prefer forms with u, e.g. French Roumanie and Swedish Rumänien, Spanish Rumania, Polish Rumunia, Russian Румыния, Japanese ルーマニア.
1859–1862: United Principalities of Moldavia and Wallachia 1862–1866: Romanian United Principalities or Romania 1866–1881: Romania or Principality of Romania 1881–1947: Kingdom of Romania or Romania 1947–1965: Romanian People's Republic or Romania 1965–December, 1989: Socialist Republic of Romania or Romania December, 1989–present: Romania Human remains found in Peștera cu Oase, radiocarbon dated as being from circa 40,000 years ago, represent the oldest known Homo sapiens in Europe. Neolithic techniques and agriculture spread after the arrival of a mixed group of people from Thessaly in the 6th millenium BC. Excavations near a salt spring at Lunca yielded the earliest evidence for salt exploitation in Europe; the first permanent settlements appeared in the Neolithic. Some of them developed into "proto-cities"; the Cucuteni–Trypillia culture—the best known archaeological culture of Old Europe—flourished in Muntenia, southeastern Transylvania and northeastern Moldavia in the 3rd m
Great Mosque of Kairouan
The Great Mosque of Kairouan known as the Mosque of Uqba, is a mosque situated in the UNESCO World Heritage town of Kairouan, Tunisia. Established by the Arab general Uqba ibn Nafi in 670 AD at the founding of the city of Kairouan, the mosque is spread over a surface area of 9,000 square metres and it is one of the oldest places of worship in the Islamic world, as well as a model for all mosques in the Maghreb; the Great Mosque of Kairouan is one of the most impressive and largest Islamic monuments in North Africa. This space contains a marble-paved courtyard and a square minaret. In addition to its spiritual prestige, the Mosque of Uqba is one of the masterpieces of Islamic architecture, notable among other things for the first Islamic use of the horseshoe arch. Under the Aghlabids, huge works gave the mosque its present aspect; the fame of the Mosque of Uqba and of the other holy sites at Kairouan helped the city to develop and repopulate increasingly. The university, consisting of scholars who taught in the mosque, was a centre of education both in Islamic thought and in the secular sciences.
Its role can be compared to that of the University of Paris in the Middle Ages. With the decline of the city of Kairouan from the mid-11th century, the centre of intellectual thought moved to the University of Ez-Zitouna in Tunis. Located in the north-east of the medina of Kairouan, the mosque is in the intramural district of Houmat al-Jami; this location corresponded to the heart of the urban fabric of the city founded by Uqba ibn Nafi. However given the natural lay of the land crossed by several tributaries of the wadis, the urban development of the city spread southwards. Human factors including Hilalian's invasions in 449 AH led to the decline of the city and halted development. For all these reasons, the mosque which once occupies the center of the medina when first built in 670 is now on the easternmost quarter abutting the city walls; the building is a vast irregular quadrilateral covering some 9,000 m2. It is longer on the east side than the west, shorter on the north side the south; the main minaret is centered on the north.
From the outside, the Great Mosque of Kairouan is a fortress-like building with its 1.90 metres thick massive ocher walls, a composite of well-worked stones with intervening courses of rubble stone and baked bricks. The corner towers measuring 4.25 metres on each side are buttressed with solid projecting supports. Structurally given the soft grounds subject to compaction, the buttressed towers added stability to the entire mosque. Despite the austere façades, the rhythmic patterns of buttresses and towering porches, some surmounted by cupolas, give the sanctuary a sense of striking sober grandeur. At the foundation of Kairouan in 670, the Arab general and conqueror Uqba Ibn Nafi chose the site of his mosque in the centre of the city, near the headquarters of the governor. Around 690, shortly after its construction, the mosque was destroyed during the occupation of Kairouan by the Berbers conducted by Kusaila, it was rebuilt by the Ghassanid general Hasan ibn al-Nu'man in 703. With the gradual increase of the population of Kairouan and the consequent increase in the number of faithful, Hisham ibn Abd al-Malik, Umayyad Caliph in Damascus, charged his governor Bishr ibn Safwan to carry out development work in the city which include the renovation and expansion of the mosque around the years 724–728.
In view of its expansion, he rebuilt it with the exception of the mihrab. It was under his auspices. In 774, a new reconstruction accompanied by modifications and embellishments took place under the direction of the Abbasid governor Yazid Ibn Hatim. Under the rule of Aghlabid sovereigns, Kairouan was at its apogee, the mosque profited from this period of stability and prosperity. In 836, Ziadet-Allah I reconstructed the mosque once more: this is when the building acquired, at least in its entirety, the appearance we see today. At the same time, the mihrab's ribbed dome on squinches was raised. Around 862–863, Abul Ibrahim enlarged the oratory, with three bays to the north, added the cupola over the arched portico which precedes the prayer hall. In 875 Ibrahim II built another three bays, thereby reducing the size of the courtyard, further limited on the three other sides by the addition of double galleries; the current state of the mosque can be traced back to the reign of Aghlabids—no element is earlier than the ninth century besides the mihrab—except for some partial restorations and a few additions made in 1025 during the reign of Zirids, 1248 and 1293–1294 under the reign of Hafsids, 1618 at the time of mouradites beys, in the late nineteenth and early twentieth century.
In 1967, major restoration works, executed during five years and conducted under the direction of the National Institute of Archeology and Art, were achieved throughout the monument, were ended with an official reopening of the mosque during the celebration of Mawlid of 1972. Several centuries after its founding, the Great Mosque of Kairouan is the subject of numerous descriptions by Arab historians and geographers in the Middle Ages; the stories concern the different phases of construction and expansion of the sanctuary, the successive contributions of many princes to the interior decoration. Among the authors who have written on the subject and whose stories have survived are Al
Culture is the social behavior and norms found in human societies. Culture is considered a central concept in anthropology, encompassing the range of phenomena that are transmitted through social learning in human societies. Cultural universals are found in all human societies; the concept of material culture covers the physical expressions of culture, such as technology and art, whereas the immaterial aspects of culture such as principles of social organization, philosophy and science comprise the intangible cultural heritage of a society. In the humanities, one sense of culture as an attribute of the individual has been the degree to which they have cultivated a particular level of sophistication in the arts, education, or manners; the level of cultural sophistication has sometimes been seen to distinguish civilizations from less complex societies. Such hierarchical perspectives on culture are found in class-based distinctions between a high culture of the social elite and a low culture, popular culture, or folk culture of the lower classes, distinguished by the stratified access to cultural capital.
In common parlance, culture is used to refer to the symbolic markers used by ethnic groups to distinguish themselves visibly from each other such as body modification, clothing or jewelry. Mass culture refers to the mass-produced and mass mediated forms of consumer culture that emerged in the 20th century; some schools of philosophy, such as Marxism and critical theory, have argued that culture is used politically as a tool of the elites to manipulate the lower classes and create a false consciousness, such perspectives are common in the discipline of cultural studies. In the wider social sciences, the theoretical perspective of cultural materialism holds that human symbolic culture arises from the material conditions of human life, as humans create the conditions for physical survival, that the basis of culture is found in evolved biological dispositions; when used as a count noun, a "culture" is the set of customs and values of a society or community, such as an ethnic group or nation. Culture is the set of knowledge acquired over time.
In this sense, multiculturalism values the peaceful coexistence and mutual respect between different cultures inhabiting the same planet. Sometimes "culture" is used to describe specific practices within a subgroup of a society, a subculture, or a counterculture. Within cultural anthropology, the ideology and analytical stance of cultural relativism holds that cultures cannot be objectively ranked or evaluated because any evaluation is situated within the value system of a given culture; the modern term "culture" is based on a term used by the Ancient Roman orator Cicero in his Tusculanae Disputationes, where he wrote of a cultivation of the soul or "cultura animi," using an agricultural metaphor for the development of a philosophical soul, understood teleologically as the highest possible ideal for human development. Samuel Pufendorf took over this metaphor in a modern context, meaning something similar, but no longer assuming that philosophy was man's natural perfection, his use, that of many writers after him, "refers to all the ways in which human beings overcome their original barbarism, through artifice, become human."In 1986, philosopher Edward S.
Casey wrote, "The word culture meant'place tilled' in Middle English, the same word goes back to Latin colere,'to inhabit, care for, worship' and cultus,'A cult a religious one.' To be cultural, to have a culture, is to inhabit a place sufficiently intensive to cultivate it—to be responsible for it, to respond to it, to attend to it caringly." Culture described by Richard Velkley:... meant the cultivation of the soul or mind, acquires most of its modern meaning in the writings of the 18th-century German thinkers, who were on various levels developing Rousseau's criticism of "modern liberalism and Enlightenment". Thus a contrast between "culture" and "civilization" is implied in these authors when not expressed as such. In the words of anthropologist E. B. Tylor, it is "that complex whole which includes knowledge, art, law and any other capabilities and habits acquired by man as a member of society." Alternatively, in a contemporary variant, "Culture is defined as a social domain that emphasizes the practices and material expressions, over time, express the continuities and discontinuities of social meaning of a life held in common.
The Cambridge English Dictionary states that culture is "the way of life the general customs and beliefs, of a particular group of people at a particular time." Terror management theory posits that culture is a series of activities and worldviews that provide humans with the basis for perceiving themselves as "person of worth within the world of meaning"—raising themselves above the physical aspects of existence, in order to deny the animal insignificance and death that Homo sapiens became aware of when they acquired a larger brain. The word is used in a general sense as the evolved ability to categorize and represent experiences with symbols and to act imaginatively and creatively; this ability arose with the evolution of behavioral modernity in humans around 50,000 years ago, is thought to be unique to humans, although some other species have demonstrated similar, though much less complex, abilities for social learning. It is used to denote the co
The Internet is the global system of interconnected computer networks that use the Internet protocol suite to link devices worldwide. It is a network of networks that consists of private, academic and government networks of local to global scope, linked by a broad array of electronic and optical networking technologies; the Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web, electronic mail and file sharing. Some publications no longer capitalize "internet"; the origins of the Internet date back to research commissioned by the federal government of the United States in the 1960s to build robust, fault-tolerant communication with computer networks. The primary precursor network, the ARPANET served as a backbone for interconnection of regional academic and military networks in the 1980s; the funding of the National Science Foundation Network as a new backbone in the 1980s, as well as private funding for other commercial extensions, led to worldwide participation in the development of new networking technologies, the merger of many networks.
The linking of commercial networks and enterprises by the early 1990s marked the beginning of the transition to the modern Internet, generated a sustained exponential growth as generations of institutional and mobile computers were connected to the network. Although the Internet was used by academia since the 1980s, commercialization incorporated its services and technologies into every aspect of modern life. Most traditional communication media, including telephony, television, paper mail and newspapers are reshaped, redefined, or bypassed by the Internet, giving birth to new services such as email, Internet telephony, Internet television, online music, digital newspapers, video streaming websites. Newspaper and other print publishing are adapting to website technology, or are reshaped into blogging, web feeds and online news aggregators; the Internet has enabled and accelerated new forms of personal interactions through instant messaging, Internet forums, social networking. Online shopping has grown exponentially both for major retailers and small businesses and entrepreneurs, as it enables firms to extend their "brick and mortar" presence to serve a larger market or sell goods and services online.
Business-to-business and financial services on the Internet affect supply chains across entire industries. The Internet has no single centralized governance in either technological implementation or policies for access and usage; 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. The technical underpinning and standardization of the core protocols is an activity of the Internet Engineering Task Force, a non-profit organization of loosely affiliated international participants that anyone may associate with by contributing technical expertise. In November 2006, the Internet was included on USA Today's list of New Seven Wonders; when the term Internet is used to refer to the specific global system of interconnected Internet Protocol networks, the word is a proper noun that should be written with an initial capital letter.
In common use and the media, it is erroneously not capitalized, viz. the internet. Some guides specify that the word should be capitalized when used as a noun, but not capitalized when used as an adjective; the Internet is often referred to as the Net, as a short form of network. As early as 1849, the word internetted was used uncapitalized as an adjective, meaning interconnected or interwoven; the designers of early computer networks used internet both as a noun and as a verb in shorthand form of internetwork or internetworking, meaning interconnecting computer networks. The terms Internet and World Wide Web are used interchangeably in everyday speech. However, the World Wide Web or the Web is only one of a large number of Internet services; the Web is a collection of interconnected documents and other web resources, linked by hyperlinks and URLs. As another point of comparison, Hypertext Transfer Protocol, or HTTP, is the language used on the Web for information transfer, yet it is just one of many languages or protocols that can be used for communication on the Internet.
The term Interweb is a portmanteau of Internet and World Wide Web used sarcastically to parody a technically unsavvy user. Research into packet switching, one of the fundamental Internet technologies, started in the early 1960s in the work of Paul Baran and Donald Davies. Packet-switched networks such as the NPL network, ARPANET, the Merit Network, CYCLADES, Telenet were developed in the late 1960s and early 1970s; the ARPANET project led to the development of protocols for internetworking, by which multiple separate networks could be joined into a network of networks. ARPANET development began with two network nodes which were interconnected between the Network Measurement Center at the University of California, Los Angeles Henry Samueli School of Engineering and Applied Science directed by Leonard Kleinrock, the NLS system at SRI International by Douglas Engelbart in Menlo Park, California, on 29 October 1969; the third site was the Culler-Fried Interactive Mathematics Center at the University of California, Santa Barbara, followed by the University of
A festival is an event ordinarily celebrated by a community and centering on some characteristic aspect of that community and its religion or cultures. It is marked as a local or national holiday, mela, or eid. Next to religion and folklore, a significant origin is agricultural. Food is such a vital resource. Religious commemoration and thanksgiving for good harvests are blended in events that take place in autumn, such as Halloween in the northern hemisphere and Easter in the southern. Festivals serve to fulfill specific communal purposes in regard to commemoration or thanking to the gods and goddesses. Celebrations offer a sense of belonging for religious, social, or geographical groups, contributing to group cohesiveness, they may provide entertainment, important to local communities before the advent of mass-produced entertainment. Festivals that focus on cultural or ethnic topics seek to inform community members of their traditions. In Ancient Greece and Rome, festivals such as the Saturnalia were associated with social organisation and political processes as well as religion.
In modern times, festivals may be attended by strangers such as tourists, who are attracted to some of the more eccentric or historical ones. The Philippines is one example of a modern society with a large number of festivals, as each day of the year has at least one specific celebration. There are more than 42,000 known major and minor festivals in the country, the majority of which are specific to the barangay level; the word "festival" was used as an adjective from the late fourteenth century, deriving from Latin via Old French. In Middle English, a "festival dai" was a religious holiday, its first recorded used as a noun was in 1589. Feast first came into usage as a noun circa 1200, its first recorded use as a verb was circa 1300; the term "feast" is used in common secular parlance as a synonym for any large or elaborate meal. When used as in the meaning of a festival, most refers to a religious festival rather than a film or art festival. In the Philippines and many other former Spanish colonies, the Spanish word fiesta is used to denote a communal religious feast to honor a patron saint.
Many festivals have religious origins and entwine cultural and religious significance in traditional activities. The most important religious festivals such as Christmas, Rosh Hashanah and Eid al-Adha serve to mark out the year. Others, such as harvest festivals, celebrate seasonal change. Events of historical significance, such as important military victories or other nation-building events provide the impetus for a festival. An early example is the festival established by Ancient Egyptian Pharaoh Ramesses III celebrating his victory over the Libyans. In many countries, royal holidays commemorate dynastic events just as agricultural holidays are about harvests. Festivals are commemorated annually. There are numerous types of festivals in the world and most countries celebrate important events or traditions with traditional cultural events and activities. Most culminate in the consumption of specially prepared food and they bring people together. Festivals are strongly associated with national holidays.
Lists of national festivals are published to make participation easier. Among many religions, a feast is a set of celebrations in honour of God. A feast and a festival are interchangeable. Most religions have festivals that recur annually and some, such as Passover and Eid al-Adha are moveable feasts – that is, those that are determined either by lunar or agricultural cycles or the calendar in use at the time; the Sed festival, for example, celebrated the thirtieth year of an Egyptian pharaoh's rule and every three years after that. In the Christian liturgical calendar, there are two principal feasts, properly known as the Feast of the Nativity of our Lord and the Feast of the Resurrection. In the Catholic, Eastern Orthodox, Anglican liturgical calendars there are a great number of lesser feasts throughout the year commemorating saints, sacred events or doctrines. In the Philippines, each day of the year has at least one specific religious festival, either from Catholic, Islamic, or indigenous origins.
Buddhist religious festivals, such as Esala Perahera are held in Sri Thailand. Hindu festivals, such as Holi are ancient; the Sikh community celebrates the Vaisakhi festival marking the new birth of the Khalsa. Among the many offspring of general arts festivals are more specific types of festivals, including ones that showcase intellectual or creative achievement such as science festivals, literary festivals and music festivals. Sub-categories include rock festivals, jazz festivals and buskers festivals. In the Philippines, aside from numerous art festivals scattered throughout the year, February is known as national arts month, the culmination of all art festivals in the entire archipelago. Film festivals involve the screenings of several different films, are held annually; some of the most significant film festivals include the Berlin International Film Festival, the Venice Film Festival and the Cannes Film Festival. A food festival is an event celebrating drink; these highlight the output of producers from a certain region.
Some food festivals are focused on a particular item of food, such as the National Peanut Festival in
