The Himalayas prevent cold Central Asian katabatic winds from blowing in, keeping the bulk of the Indian subcontinent warmer than most locations at similar latitudes. The Thar Desert plays a crucial role in attracting the moisture-laden south-west summer monsoon winds that, between June and October, provide
11856-462: The Himalayas. This had the effect of lowering endemism among India's mammals, which stands at 12.6%, contrasting with 45.8% among reptiles and 55.8% among amphibians. Among endemics are the vulnerable hooded leaf monkey and the threatened Beddome's toad of the Western Ghats. India contains 172 IUCN -designated threatened animal species , or 2.9% of endangered forms. These include
12012-401: The Indian elites, the sultanate largely left its vast non-Muslim subject population to its own laws and customs. By repeatedly repulsing Mongol raiders in the 13th century, the sultanate saved India from the devastation visited on West and Central Asia, setting the scene for centuries of migration of fleeing soldiers, learned men, mystics, traders, artists, and artisans from that region into
12168-772: The Islamic period. It was made by Nastulus in 927-28 AD and is now a treasure of the Kuwait National Museum . In about 964 AD, the Persian astronomer Abd al-Rahman al-Sufi , writing in his Book of Fixed Stars , described a "nebulous spot" in the Andromeda constellation , the first definitive reference to what is now known to be the Andromeda Galaxy , the nearest spiral galaxy to the Milky Way . The geocentric system developed by Ptolemy placed
12324-463: The Mughals united their far-flung realms through loyalty, expressed through a Persianised culture, to an emperor who had near-divine status. The Mughal state's economic policies, deriving most revenues from agriculture and mandating that taxes be paid in the well-regulated silver currency, caused peasants and artisans to enter larger markets. The relative peace maintained by the empire during much of
12480-783: The Persian contribution to this new Islamic civilization is of immense importance. The work of Iranians can be seen in every field of cultural endeavor, including Arabic poetry, to which poets of Iranian origin composing their poems in Arabic made a very significant contribution." While cultural influence used to radiate outward from Baghdad, after the Mongol destruction of the Abbasid Caliphate, Arab influence decreased. Iran and Central Asia, benefiting from increased cross-cultural access to East Asia under Mongol rule , flourished and developed more distinctively from Arab influence, such as
12636-557: The Quran and hadith. The classical theory of Islamic jurisprudence elaborates how scriptures should be interpreted from the standpoint of linguistics and rhetoric. It also comprises methods for establishing authenticity of hadith and for determining when the legal force of a scriptural passage is abrogated by a passage revealed at a later date. In addition to the Quran and sunnah, the classical theory of Sunni fiqh recognizes two other sources of law: juristic consensus ( ijmaʿ ) and analogical reasoning ( qiyas ). It therefore studies
12792-712: The adherents of the Church of the East ( Nestorians ), contributed to Islamic civilization during the reign of the Umayyads and the Abbasids by translating works of Greek philosophers and ancient science to Syriac and afterwards to Arabic . They also excelled in many fields, in particular philosophy , science (such as Hunayn ibn Ishaq , Yusuf Al-Khuri , Al Himsi , Qusta ibn Luqa , Masawaiyh , Patriarch Eutychius , and Jabril ibn Bukhtishu ) and theology . For
12948-557: The advent of independence in 1947, but tempered by the partition of India into two states: India and Pakistan. Vital to India's self-image as an independent nation was its constitution, completed in 1950, which put in place a secular and democratic republic. Per the London Declaration , India retained its membership of the Commonwealth , becoming the first republic within it. Economic liberalisation, which began in
13104-512: The agricultural sector 18.1%. India's foreign exchange remittances of US$ 100 billion in 2022, highest in the world, were contributed to its economy by 32 million Indians working in foreign countries. Major agricultural products include rice, wheat, oilseed, cotton, jute, tea, sugarcane, and potatoes. Major industries include textiles, telecommunications, chemicals, pharmaceuticals, biotechnology, food processing, steel, transport equipment, cement, mining, petroleum, machinery, and software. In 2006,
13260-559: The ancients" or "rational sciences", from Islamic religious sciences. Sciences of the former type flourished for several centuries, and their transmission formed part of the educational framework in classical and medieval Islam. In some cases, they were supported by institutions such as the House of Wisdom in Baghdad, but more often they were transmitted informally from teacher to student. The University of Al Karaouine , founded in 859 AD,
13416-507: The application and limits of analogy, as well as the value and limits of consensus, along with other methodological principles, some of which are accepted by only certain legal schools. This interpretive apparatus is brought together under the rubric of ijtihad , which refers to a jurist's exertion in an attempt to arrive at a ruling on a particular question. The theory of Twelver Shia jurisprudence parallels that of Sunni schools with some differences, such as recognition of reason ( ʿaql ) as
13572-420: The attempts to impose a caliphal writ in matters of religious orthodoxy ultimately failed. This controversy persisted until al-Ash'ari (874–936) found a middle ground between Mu'tazilite rationalism and Hanbalite literalism, using the rationalistic methods championed by Mu'tazilites to defend most substantive tenets maintained by ahl al-hadith . A rival compromise between rationalism and literalism emerged from
13728-498: The banking sector, 44th in business sophistication, and 39th in innovation, ahead of several advanced economies. With seven of the world's top 15 information technology outsourcing companies based in India, as of 2009 , the country is viewed as the second-most favourable outsourcing destination after the United States. India is ranked 39th in the Global Innovation Index in 2024. As of 2023 , India's consumer market
13884-663: The beginnings of a nonviolent movement of non-co-operation, of which Mahatma Gandhi would become the leader and enduring symbol. During the 1930s, slow legislative reform was enacted by the British; the Indian National Congress won victories in the resulting elections. The next decade was beset with crises: Indian participation in World War ;II , the Congress's final push for non-co-operation, and an upsurge of Muslim nationalism . All were capped by
14040-400: The boundaries of the schools became clearly delineated, the authority of their doctrinal tenets came to be vested in a master jurist from earlier times, who was henceforth identified as the school's founder. In the course of the first three centuries of Islam, all legal schools came to accept the broad outlines of classical legal theory, according to which Islamic law had to be firmly rooted in
14196-567: The caliphate, or to "six and a half centuries", while another would have it end after only a few decades of Rashidun conquests, with the death of Umar and the First Fitna . During the early 20th century, the term was used only occasionally and often referred to as the early military successes of the Rashidun caliphs . It was only in the second half of the 20th century that the term came to be used with any frequency, now mostly referring to
14352-405: The caliphates is a convenient cut-off point based on a historical landmark, but it can be argued that Islamic culture had entered a gradual decline much earlier; thus, Khan (2003) identifies the proper golden age as being the two centuries between 750 and 950, arguing that the beginning loss of territories under Harun al-Rashid worsened after the death of al-Ma'mun in 833, and that the crusades in
14508-495: The coasts of southern and eastern India. As the empire disintegrated, many among these elites were able to seek and control their own affairs. By the early 18th century, with the lines between commercial and political dominance being increasingly blurred, a number of European trading companies, including the English East India Company , had established coastal outposts. The East India Company's control of
14664-452: The commercialisation of agriculture in the second half of the 19th century was marked by economic setbacks, and many small farmers became dependent on the whims of far-away markets. There was an increase in the number of large-scale famines , and, despite the risks of infrastructure development borne by Indian taxpayers, little industrial employment was generated for Indians. There were also salutary effects: commercial cropping, especially in
14820-625: The contribution of petrochemical and engineering goods to total exports grew from 14% to 42%. India was the world's second-largest textile exporter after China in the 2013 calendar year. Averaging an economic growth rate of 7.5% for several years prior to 2007, India has more than doubled its hourly wage rates during the first decade of the 21st century. Some 431 million Indians have left poverty since 1985; India's middle classes are projected to number around 580 million by 2030. Though ranking 68th in global competitiveness , as of 2010 , India ranks 17th in financial market sophistication, 24th in
14976-630: The cost of increasing economic inequality. India is a nuclear-weapon state , which ranks high in military expenditure . It has disputes over Kashmir with its neighbours, Pakistan and China, unresolved since the mid-20th century. Among the socio-economic challenges India faces are gender inequality , child malnutrition , and rising levels of air pollution . India's land is megadiverse , with four biodiversity hotspots . Its forest cover comprises 21.7% of its area. India's wildlife , which has traditionally been viewed with tolerance in India's culture ,
15132-404: The cultural flourishing of science and mathematics under the caliphates during the 9th to 11th centuries (between the establishment of organised scholarship in the House of Wisdom and the beginning of the crusades ), but often extended to include part of the late 8th or the 12th to early 13th centuries. Definitions may still vary considerably. Equating the end of the golden age with the end of
15288-498: The decline theory has become the preferred paradigm in general academia. The various Quranic injunctions and Hadith (or actions of Muhammad ), which place values on education and emphasize the importance of acquiring knowledge, played a vital role in influencing the Muslims of this age in their search for knowledge and the development of the body of science. The Islamic Empire heavily patronized scholars. The money spent on
15444-581: The design and implementation of Vikrant -class aircraft carriers and Arihant -class nuclear submarines . Since the end of the Cold War , India has increased its economic, strategic, and military co-operation with the United States and the European Union . In 2008, a civilian nuclear agreement was signed between India and the United States. Although India possessed nuclear weapons at
15600-507: The early 16th century, northern India, then under mainly Muslim rulers, fell again to the superior mobility and firepower of a new generation of Central Asian warriors. The resulting Mughal Empire did not stamp out the local societies it came to rule. Instead, it balanced and pacified them through new administrative practices and diverse and inclusive ruling elites, leading to more systematic, centralised, and uniform rule. Eschewing tribal bonds and Islamic identity, especially under Akbar ,
15756-536: The early mediaeval era, Christianity , Islam , Judaism , and Zoroastrianism became established on India's southern and western coasts. Muslim armies from Central Asia intermittently overran India's northern plains, eventually founding the Delhi Sultanate and drawing northern India into the cosmopolitan networks of mediaeval Islam . In the 15th century, the Vijayanagara Empire created
15912-727: The east. To the south, the remaining peninsular landmass, the Deccan Plateau , is flanked on the west and east by coastal ranges known as the Western and Eastern Ghats ; the plateau contains the country's oldest rock formations, some over one billion years old. Constituted in such fashion, India lies to the north of the equator between 6° 44′ and 35° 30′ north latitude and 68° 7′ and 97° 25′ east longitude. India's coastline measures 7,517 kilometres (4,700 mi) in length; of this distance, 5,423 kilometres (3,400 mi) belong to peninsular India and 2,094 kilometres (1,300 mi) to
16068-521: The end of the Islamic Golden Age as late as the end of 15th to 16th centuries, including the rise of the Islamic gunpowder empires . The metaphor of a golden age began to be applied in 19th-century literature about Islamic history , in the context of the western aesthetic fashion known as Orientalism . The author of a Handbook for Travelers in Syria and Palestine in 1868 observed that
16224-513: The endangered Bengal tiger and the Ganges river dolphin . Critically endangered species include the gharial , a crocodilian ; the great Indian bustard ; and the Indian white-rumped vulture , which has become nearly extinct by having ingested the carrion of diclofenac -treated cattle. Before they were extensively used for agriculture and cleared for human settlement, the thorn forests of Punjab were mingled at intervals with open grasslands that were grazed by large herds of blackbuck preyed on by
16380-577: The essence of objects flows into the eyes. Alhazen correctly argued that vision occurred when light, traveling in straight lines, reflects off an object into the eyes. Al-Biruni wrote of his insights into light, stating that its velocity must be immense when compared to the speed of sound. The early Islamic period saw the establishment of some of the longest lived theoretical frameworks in alchemy and chemistry . The sulfur-mercury theory of metals , first attested in pseudo-Apollonius of Tyana's Sirr al-khalīqa ("The Secret of Creation", c. 750–850) and in
16536-738: The institution, and it placed its holder within a genealogy of scholars, which was the only recognized hierarchy in the educational system. While formal studies in madrasas were open only to men, women of prominent urban families were commonly educated in private settings and many of them received and later issued ijazas in hadith studies, calligraphy and poetry recitation. Working women learned religious texts and practical skills primarily from each other, though they also received some instruction together with men in mosques and private homes. Madrasas were devoted principally to study of law, but they also offered other subjects such as theology, medicine, and mathematics. The madrasa complex usually consisted of
16692-494: The largest single party, was able to form a minority government led by P. V. Narasimha Rao . A two-year period of political turmoil followed the general election of 1996 . Several short-lived alliances shared power at the centre. The BJP formed a government briefly in 1996; it was followed by two comparatively long-lasting United Front coalitions, which depended on external support. There were two prime ministers during this period; H.D. Deve Gowda and I.K. Gujral . In 1998 ,
16848-478: The life of its exemplar, Mahavira . Buddhism , based on the teachings of Gautama Buddha , attracted followers from all social classes excepting the middle class; chronicling the life of the Buddha was central to the beginnings of recorded history in India. In an age of increasing urban wealth, both religions held up renunciation as an ideal, and both established long-lasting monastic traditions. Politically, by
17004-526: The loose-knit Maurya and Gupta Empires based in the Ganges Basin . Their collective era was suffused with wide-ranging creativity, but also marked by the declining status of women, and the incorporation of untouchability into an organised system of belief. In South India , the Middle kingdoms exported Dravidian-languages scripts and religious cultures to the kingdoms of Southeast Asia . In
17160-471: The majority of India's rainfall. Four major climatic groupings predominate in India: tropical wet , tropical dry , subtropical humid , and montane . Temperatures in India have risen by 0.7 °C (1.3 °F) between 1901 and 2018. Climate change in India is often thought to be the cause. The retreat of Himalayan glaciers has adversely affected the flow rate of the major Himalayan rivers, including
17316-413: The medieval Islamic world include the synthesis of ammonium chloride from organic substances as described in the works attributed to Jābir, and Abū Bakr al-Rāzī's experiments with vitriol , which would eventually lead to the discovery of mineral acids like sulfuric acid and nitric acid by thirteenth century Latin alchemists such as pseudo-Geber . Al-Biruni (973–1050) estimated the radius of
17472-404: The most beautiful mosques of Damascus were "like Mohammedanism itself, now rapidly decaying" and relics of "the golden age of Islam". There is no unambiguous definition of the term, and depending on whether it is used with a focus on cultural or on military achievement, it may be taken to refer to rather disparate time spans. Thus, one 19th century author would have it extend to the duration of
17628-453: The movement of the capital in 762 AD to Baghdad, translators were sponsored to translate Greek texts into Arabic. This translation period led to many major scientific works from Galen , Ptolemy , Aristotle , Euclid , Archimedes , and Apollonius being translated into Arabic. From these translations previously lost knowledge of the cosmos was now being used to advance current astrological thinkers. The second key factor of astronomy's growth
17784-496: The names that come directly from Arabic origins or are the translations of Ptolemy's Greek descriptions which are still in use today. Alhazen played a role in the development of optics . One of the prevailing theories of vision in his time and place was the emission theory supported by Euclid and Ptolemy, where sight worked by the eye emitting rays of light, and the other was the Aristotelean theory that sight worked when
17940-420: The nation to liberalise its economy ; since then, it has moved increasingly towards a free-market system by emphasising both foreign trade and direct investment inflows. India has been a member of World Trade Organization since 1 January 1995. The 522-million-worker Indian labour force is the world's second largest , as of 2017 . The service sector makes up 55.6% of GDP, the industrial sector 26.3% and
18096-445: The newly canalled Punjab, led to increased food production for internal consumption. The railway network provided critical famine relief, notably reduced the cost of moving goods, and helped nascent Indian-owned industry. After World War I , in which approximately one million Indians served , a new period began. It was marked by British reforms but also repressive legislation , by more strident Indian calls for self-rule, and by
18252-564: The planets. One of the first to criticize this model was Ibn al-Haytham , a leader of physics in the 11th century in Cairo. Then in the 13th century Nasir al-Din al-Tusi constructed the Maragha Observatory in what is today Iran. Al-Tusi found the equant dissatisfying and replaced it by adding a geometrical technique called a Tusi-couple , which generates linear motion from the sum of two circular motions. Then, Ibn al-Shatir who
18408-637: The prominent centers of learning and transmission of classical wisdom were Christian colleges such as the School of Nisibis and the School of Edessa , the pagan center of learning in Harran , and the renowned hospital and medical Academy of Gondishapur, which was the intellectual, theological and scientific center of the Church of the East. Many scholars of the House of Wisdom were of Christian background and it
18564-546: The proportion of the area of a forest covered by its tree canopy . Very dense forest , whose canopy density is greater than 70%, occupies 3.02% of India's land area. It predominates in the tropical moist forest of the Andaman Islands , the Western Ghats , and Northeast India . Moderately dense forest , whose canopy density is between 40% and 70%, occupies 9.39% of India's land area. It predominates in
18720-548: The seas, greater resources, and more advanced military training and technology led it to increasingly assert its military strength and caused it to become attractive to a portion of the Indian elite; these factors were crucial in allowing the company to gain control over the Bengal region by 1765 and sideline the other European companies. Its further access to the riches of Bengal and the subsequent increased strength and size of its army enabled it to annex or subdue most of India by
18876-463: The share of external trade in India's GDP stood at 24%, up from 6% in 1985. In 2008, India's share of world trade was 1.7%; In 2021, India was the world's ninth-largest importer and the sixteenth-largest exporter . Major exports include petroleum products, textile goods, jewellery, software, engineering goods, chemicals, and manufactured leather goods. Major imports include crude oil, machinery, gems, fertiliser, and chemicals. Between 2001 and 2011,
19032-576: The southern supercontinent Gondwana , began a north-eastward drift caused by seafloor spreading to its south-west, and later, south and south-east. Simultaneously, the vast Tethyan oceanic crust , to its northeast, began to subduct under the Eurasian Plate . These dual processes, driven by convection in the Earth's mantle , both created the Indian Ocean and caused the Indian continental crust eventually to under-thrust Eurasia and to uplift
19188-416: The subcontinent from the north-west. The caste system , which created a hierarchy of priests, warriors, and free peasants, but which excluded indigenous peoples by labelling their occupations impure, arose during this period. On the Deccan Plateau , archaeological evidence from this period suggests the existence of a chiefdom stage of political organisation. In South India , a progression to sedentary life
19344-513: The subcontinent in the western margins of the Indus river basin 9,000 years ago, evolving gradually into the Indus Valley Civilisation of the third millennium BCE. By at least 1200 BCE , an archaic form of Sanskrit , an Indo-European language , had diffused into India from the northwest. Its evidence today is found in the hymns of the Rigveda . Preserved by an oral tradition that
19500-526: The subcontinent transitioned from the Chalcolithic cultures to the Iron Age ones. The Vedas , the oldest scriptures associated with Hinduism , were composed during this period, and historians have analysed these to posit a Vedic culture in the Punjab region and the upper Gangetic Plain . Most historians also consider this period to have encompassed several waves of Indo-Aryan migration into
19656-441: The subcontinent, thereby creating a syncretic Indo-Islamic culture in the north. The sultanate's raiding and weakening of the regional kingdoms of South India paved the way for the indigenous Vijayanagara Empire . Embracing a strong Shaivite tradition and building upon the military technology of the sultanate, the empire came to control much of peninsular India, and was to influence South Indian society for long afterwards. In
19812-405: The sun, moon, and other planets in orbit around the Earth. Ptolemy thought that the planets moved on circles called epicycles and that their centers rode on deferents . The deferents were eccentric , and the angular motion of a planet was uniform around the equant which was a point opposite the deferent center. Simply, Ptolemy's models were a mathematical system for predicting the positions of
19968-414: The support of left-leaning parties and MPs who opposed the BJP. The UPA returned to power in the 2009 general election with increased numbers, and it no longer required external support from India's communist parties . That year, Manmohan Singh became the first prime minister since Jawaharlal Nehru in 1957 and 1962 to be re-elected to a consecutive five-year term. In the 2014 general election ,
20124-677: The time and was not a party to the Nuclear Non-Proliferation Treaty, it received waivers from the International Atomic Energy Agency and the Nuclear Suppliers Group , ending earlier restrictions on India's nuclear technology and commerce. As a consequence, India became the sixth de facto nuclear weapons state. India subsequently signed co-operation agreements involving civilian nuclear energy with Russia, France,
20280-478: The tradition of commentary on the studied texts. It also involved a process of socialization of aspiring scholars, who came from virtually all social backgrounds, into the ranks of the ulema . For the first few centuries of Islam, educational settings were entirely informal, but beginning in the 11th and 12th centuries, the ruling elites began to establish institutions of higher religious learning known as madrasas in an effort to secure support and cooperation of
20436-518: The two nations have gone to war four times: in 1947 , 1965 , 1971 , and 1999 . Three of these wars were fought over the disputed territory of Kashmir , while the third, the 1971 war, followed from India's support for the independence of Bangladesh . In the late 1980s, the Indian military twice intervened abroad at the invitation of the host country: a peace-keeping operation in Sri Lanka between 1987 and 1990; and an armed intervention to prevent
20592-415: The ulema. Madrasas soon multiplied throughout the Islamic world, which helped to spread Islamic learning beyond urban centers and to unite diverse Islamic communities in a shared cultural project. Nonetheless, instruction remained focused on individual relationships between students and their teacher. The formal attestation of educational attainment, ijaza , was granted by a particular scholar rather than
20748-639: The union territories of Jammu and Kashmir , Puducherry and the National Capital Territory of Delhi , have elected legislatures and governments following the Westminster system of governance. The remaining five union territories are directly ruled by the central government through appointed administrators.

20904-495: The western part of the Indo-Gangetic plain, now turned into rich agricultural land by irrigation, its features no longer visible. Among the Indian subcontinent's notable indigenous trees are the astringent Azadirachta indica , or neem , which is widely used in rural Indian herbal medicine , and the luxuriant Ficus religiosa , or peepul , which is displayed on the ancient seals of Mohenjo-daro , and under which
21060-495: The work of al-Maturidi (d. c. 944), and, although a minority of scholars remained faithful to the early ahl al-hadith creed, Ash'ari and Maturidi theology came to dominate Sunni Islam from the 10th century on. Ibn Sina (Avicenna) and Ibn Rushd (Averroes) played a major role in interpreting the works of Aristotle, whose ideas came to dominate the non-religious thought of the Christian and Muslim worlds . According to
21216-449: The works attributed to Jābir. Substantial advances were also made in practical chemistry. The works attributed to Jābir, and those of the Persian alchemist and physician Abū Bakr al-Rāzī (c. 865–925), contain the earliest known systematic classifications of chemical substances. However, alchemists were not only interested in identifying and classifying chemical substances, but also in artificially creating them. Significant examples from
21372-444: The world in nominal per capita income and 125th in per capita income adjusted for purchasing power parity (PPP)—the vast majority of Indians fall into the low-income group. Until 1991, all Indian governments followed protectionist policies that were influenced by socialist economics. Widespread state intervention and regulation largely walled the economy off from the outside world. An acute balance of payments crisis in 1991 forced
21528-550: The world's largest city by then, to translate the known world's classical knowledge into Arabic and Persian . The period is traditionally said to have ended with the collapse of the Abbasid caliphate due to Mongol invasions and the Siege of Baghdad in 1258. There are a few alternative timelines. Some scholars extend the end date of the golden age to around 1350, including the Timurid Renaissance within it, while others place
21684-437: The world's most populous democracy since the time of its independence in 1947. It is a pluralistic , multilingual and multi-ethnic society . India's nominal per capita income increased from US$ 64 annually in 1951 to US$ 2,601 in 2022, and its literacy rate from 16.6% to 74%. During the same time, its population grew from 361 million to almost 1.4 billion, and India became the most populous country in 2023. From being
21840-537: The world's newer nations; however, in spite of its recent economic successes, freedom from want for its disadvantaged population remains a goal yet to be achieved. India accounts for the bulk of the Indian subcontinent, lying atop the Indian tectonic plate , a part of the Indo-Australian Plate . India's defining geological processes began 75 million years ago when the Indian Plate, then part of
21996-513: Was resolutely vigilant , the Rigveda records the dawning of Hinduism in India. The Dravidian languages of India were supplanted in the northern and western regions. By 400 BCE , stratification and exclusion by caste had emerged within Hinduism, and Buddhism and Jainism had arisen, proclaiming social orders unlinked to heredity. Early political consolidations gave rise to
22152-455: Was a period of scientific, economic and cultural flourishing in the history of Islam , traditionally dated from the 8th century to the 13th century. This period is traditionally understood to have begun during the reign of the Abbasid caliph Harun al-Rashid (786 to 809) with the inauguration of the House of Wisdom , which saw scholars from all over the Muslim world flock to Baghdad ,
22308-412: Was a significant step in the development of algebra, is part of the body of Persian mathematics that was eventually transmitted to Europe. Yet another Persian mathematician, Sharaf al-Dīn al-Tūsī , found algebraic and numerical solutions to various cases of cubic equations. He also developed the concept of a function . Ibn al-Haytham (Alhazen) discovered the sum formula for the fourth power, using
22464-457: Was amended in 1971 to "a sovereign, socialist , secular , democratic republic". India's form of government, traditionally described as "quasi-federal" with a strong centre and weak states, has grown increasingly federal since the late 1990s as a result of political, economic, and social changes. The Government of India comprises three branches: India is a federal union comprising 28 states and 8 union territories . All states, as well as
22620-400: Was followed by two centuries of splendid original thinking and contributions, and is known as the "golden age" of Islamic science. This so-called "golden age" is supposed to have lasted from the end of the ninth to the end of the eleventh century. The era after this period is conventionally known as the "age of decline". A survey of literature from the nineteenth century onwards demonstrates that
22776-430: Was from these countries that the rest of the world learned to make paper from linen. The centrality of scripture and its study in the Islamic tradition helped to make education a central pillar of the religion in virtually all times and places in the history of Islam. The importance of learning in the Islamic tradition is reflected in a number of hadiths attributed to Muhammad, including one that states "Seeking knowledge
22932-524: Was given by Al-Kindi (c. 801–873, also known as "Alkindus" in Europe), in Risalah fi Istikhraj al-Mu'amma ( A Manuscript on Deciphering Cryptographic Messages ) which contains the first description of the method of frequency analysis . Ibn al-Haytham (Alhazen) was a significant figure in the history of scientific method , particularly in his approach to experimentation, and has been described as
