Ulug Beg
Mīrzā Muhammad Tāraghay bin Shāhrukh ( chg, میرزا محمد طارق بن شاہ رخ, fa, میرزا محمد تراغای بن شاہ رخ), better known as Ulugh Beg () (22 March 1394 – 27 October 1449), was a Timurid sultan, as well as an astronomer and mathematician. Ulugh Beg was notable for his work in astronomy-related mathematics, such as trigonometry and spherical geometry, as well as his general interests in the arts and intellectual activities.Science in Islamic civilisation: proceedings of the international symposia: "Science institutions in Islamic civilisation", & "Science and technology in the Turkish and Islamic worl/ref> It is thought that he spoke five languages: Arabic, Persian, Turkic, Mongolian, and a small amount of Chinese. During his rule (first as a governor, then outright) the Timurid Empire achieved the cultural peak of the Timurid Renaissance through his attention and patronage. Samarkand was captured and given to Ulugh Beg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ulugh Beg Observatory
The Ulugh Beg Observatory is an observatory in Samarkand, Uzbekistan. Built in the 1420s by the Timurid astronomer Ulugh Beg. Islamic astronomers who worked at the observatory include Al-Kashi, Ali Qushji, and Ulugh Beg himself. The observatory was destroyed in 1449 and rediscovered in 1908. History Rise and decline Ulugh Beg, the son of Shāhrukh and grandson of sultan Teymūr, became the ruler of Samarkand in the 15th century AD. Ulugh Beg was very skilled in mathematics and astronomy. He taught many important astronomers; one example is the famous Ali Qushji. Many historians have tried to accurately identify dates of the events that have occurred during the Samarkand or Ulugh Beg Observatory. The differences in interpreting dates and citations of historical sources have cause inaccuracies and neglection of some events during this time. In Jamashīd al-Kāshī’s letters to Ulugh Beg’s father, you can see Ulugh Beg’s visit to the Maragha Observatory had an effect on U ...

Abdal-Latif Mirza
Abdal-Latif Mirza (c. 1420 – 9 May 1450) was the great-grandson of Central Asian emperor Timur. He was the third son of Ulugh Beg, Timurid ruler of Transoxiana (modern Uzbekistan, Tajikistan and parts of Turkmenistan, Kyrgyzstan and Kazakhstan). Early years Having been given the governorship of Balkh, Abdal-Latif Mirza served under his father. During the succession struggle that followed the death of Shah Rukh, he occupied Herat, although after Ulugh Beg left the city at the end of 1448 it was conquered by Abul-Qasim Babur Mirza. Abdal-Latif Mirza did not remain loyal to his father. Angry over the fact that he was to be passed over in the transfer of rule of Samarkand, he revolted while Ulugh Beg was marching to retake Khorasan. He defeated his father at Dimashq, near Samarkand, in the fall of 1449. Ulugh Beg later decided to surrender himself, and Abdal-Latif Mirza granted him permission to take a pilgrimage to Mecca, but while Ulugh Beg was on his way he was murdere ...

Mandarin Language
Mandarin (; ) is a group of Chinese (Sinitic) dialects that are natively spoken across most of northern and southwestern China. The group includes the Beijing dialect, the basis of the phonology of Standard Chinese, the official language of China. Because Mandarin originated in North China and most Mandarin dialects are found in the north, the group is sometimes referred to as Northern Chinese (). Many varieties of Mandarin, such as those of the Southwest (including Sichuanese) and the Lower Yangtze, are not mutually intelligible with the standard language (or are only partially intelligible). Nevertheless, Mandarin as a group is often placed first in lists of languages by number of native speakers (with nearly one billion). Mandarin is by far the largest of the seven or ten Chinese dialect groups; it is spoken by 70 percent of all Chinese speakers over a large geographical area that stretches from Yunnan in the southwest to Xinjiang in the northwest and Heilongjiang in t ...

Mongolian Language
Mongolian is the official language of Mongolia and both the most widely spoken and best-known member of the Mongolic language family. The number of speakers across all its dialects may be 5.2 million, including the vast majority of the residents of Mongolia and many of the ethnic Mongol residents of the Inner Mongolia Autonomous Region of the People's Republic of China.Estimate from Svantesson ''et al.'' (2005): 141. In Mongolia, Khalkha Mongolian is predominant, and is currently written in both Cyrillic and traditional Mongolian script. In Inner Mongolia, the language is dialectally more diverse and is written in the traditional Mongolian script. However, Mongols in both countries often use the Latin script for convenience on the Internet. In the discussion of grammar to follow, the variety of Mongolian treated is the standard written Khalkha formalized in the writing conventions and in grammar as taught in schools, but much of what is to be said is also valid for vernacular ...

Turkic Language
The Turkic languages are a language family of over 35 documented languages, spoken by the Turkic peoples of Eurasia from Eastern Europe and Southern Europe to Central Asia, East Asia, North Asia (Siberia), and Western Asia. The Turkic languages originated in a region of East Asia spanning from Mongolia to Northwest China, where Proto-Turkic language, Proto-Turkic is thought to have been spoken, from where they Turkic migration, expanded to Central Asia and farther west during the first millennium. They are characterized as a dialect continuum. Turkic languages are spoken by some 200 million people. The Turkic language with the greatest number of speakers is Turkish language, Turkish, spoken mainly in Anatolia and the Balkans; its native speakers account for about 38% of all Turkic speakers. Characteristic features such as vowel harmony, agglutination, subject-object-verb order, and lack of grammatical gender, are almost universal within the Turkic family. There is a high deg ...

Persian Language
Persian (), also known by its endonym Farsi (, ', ), is a Western Iranian language belonging to the Iranian branch of the Indo-Iranian subdivision of the Indo-European languages. Persian is a pluricentric language predominantly spoken and used officially within Iran, Afghanistan, and Tajikistan in three mutually intelligible standard varieties, namely Iranian Persian (officially known as ''Persian''), Dari Persian (officially known as ''Dari'' since 1964) and Tajiki Persian (officially known as ''Tajik'' since 1999).Siddikzoda, S. "Tajik Language: Farsi or not Farsi?" in ''Media Insight Central Asia #27'', August 2002. It is also spoken natively in the Tajik variety by a significant population within Uzbekistan, as well as within other regions with a Persianate history in the cultural sphere of Greater Iran. It is written officially within Iran and Afghanistan in the Persian alphabet, a derivation of the Arabic script, and within Tajikistan in the Tajik alphabet, a der ...

Arabic
Arabic (, ' ; , ' or ) is a Semitic languages, Semitic language spoken primarily across the Arab world.Semitic languages: an international handbook / edited by Stefan Weninger; in collaboration with Geoffrey Khan, Michael P. Streck, Janet C. E.Watson; Walter de Gruyter GmbH & Co. KG, Berlin/Boston, 2011. Having emerged in the 1st century, it is named after the Arabs, Arab people; the term "Arab" was initially used to describe those living in the Arabian Peninsula, as perceived by geographers from ancient Greece. Since the 7th century, Arabic has been characterized by diglossia, with an opposition between a standard Prestige (sociolinguistics), prestige language—i.e., Literary Arabic: Modern Standard Arabic (MSA) or Classical Arabic—and diverse vernacular varieties, which serve as First language, mother tongues. Colloquial dialects vary significantly from MSA, impeding mutual intelligibility. MSA is only acquired through formal education and is not spoken natively. It is ...

Spherical Geometry
300px, A sphere with a spherical triangle on it. Spherical geometry is the geometry of the two-dimensional surface of a sphere. In this context the word "sphere" refers only to the 2-dimensional surface and other terms like "ball" or "solid sphere" are used for the surface together with its 3-dimensional interior. Long studied for its practical applications to navigation and astronomy, spherical geometry bears many similarities and relationships to, and important differences from, Euclidean plane geometry. The sphere has for the most part been studied as a part of 3-dimensional Euclidean geometry (often called solid geometry), the surface thought of as placed inside an ambient 3-d space. It can also be analyzed by "intrinsic" methods that only involve the surface itself, and do not refer to, or even assume the existence of, any surrounding space outside or inside the sphere. Because a sphere and a plane differ geometrically, (intrinsic) spherical geometry has some featu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trigonometry
Trigonometry () is a branch of mathematics that studies relationships between side lengths and angles of triangles. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies. The Greeks focused on the calculation of chords, while mathematicians in India created the earliest-known tables of values for trigonometric ratios (also called trigonometric functions) such as sine. Throughout history, trigonometry has been applied in areas such as geodesy, surveying, celestial mechanics, and navigation. Trigonometry is known for its many identities. These trigonometric identities are commonly used for rewriting trigonometrical expressions with the aim to simplify an expression, to find a more useful form of an expression, or to solve an equation. History Sumerian astronomers studied angle measure, using a division of circles into 360 degrees. They, and later the Babylonians, studied the ratios of the sides of ...

Islamic Mathematics
Mathematics during the Golden Age of Islam, especially during the 9th and 10th centuries, was built on Greek mathematics (Euclid, Archimedes, Apollonius) and Indian mathematics (Aryabhata, Brahmagupta). Important progress was made, such as full development of the decimal place-value system to include decimal fractions, the first systematised study of algebra, and advances in geometry and trigonometry. Arabic works played an important role in the transmission of mathematics to Europe during the 10th—12th centuries. Concepts Algebra The study of algebra, the name of which is derived from the Arabic word meaning completion or "reunion of broken parts", flourished during the Islamic golden age. Muhammad ibn Musa al-Khwarizmi, a Persian scholar in the House of Wisdom in Baghdad was the founder of algebra, is along with the Greek mathematician Diophantus, known as the father of algebra. In his book ''The Compendious Book on Calculation by Completion and Balancing'', Al-Khwa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Islamic Astronomy
Islamic astronomy comprises the Astronomy, astronomical developments made in the Islamic world, particularly during the Islamic Golden Age (9th–13th centuries), and mostly written in the Arabic language. These developments mostly took place in the Middle East, Central Asia, Al-Andalus, and North Africa, and later in the Far East and History of India, India. It closely parallels the genesis of other Islamic sciences in its assimilation of foreign material and the amalgamation of the disparate elements of that material to create a science with Islamic characteristics. These included Greek astronomy, Greek, Sassanid Empire, Sassanid, and Indian astronomy, Indian works in particular, which were translated and built upon. Islamic astronomy played a significant role in the revival of Byzantine science, Byzantine and Science in Medieval Western Europe, EuropeanSaliba (1999). astronomy following the Dark Ages (historiography), loss of knowledge during the early medieval period, notably ...

Sultan
Sultan (; ar, سلطان ', ) is a position with several historical meanings. Originally, it was an Arabic abstract noun meaning "strength", "authority", "rulership", derived from the verbal noun ', meaning "authority" or "power". Later, it came to be used as the title of certain rulers who claimed almost full sovereignty (i.e., not having dependence on any higher ruler) without claiming the overall caliphate, or to refer to a powerful governor of a province within the caliphate. The adjectival form of the word is "sultanic", and the state and territories ruled by a sultan, as well as his office, are referred to as a sultanate ( '. The term is distinct from king ( '), despite both referring to a sovereign ruler. The use of "sultan" is restricted to Muslim countries, where the title carries religious significance, contrasting the more secular ''king'', which is used in both Muslim and non-Muslim countries. Brunei and Oman are the only independent countries which retain the ti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
