Abu Sa'id Al-Darir Al-Jurjani
Abu Sa'id al-Dharir al-Jurjani (), also Gurgani, was a 9th-century Persian mathematician and astronomer from Gurgan (Jurjan), Iran. He wrote a treatise on geometrical problems and another on the drawing of the meridian. George Sarton considers him a pupil of Ibn al-A'rabi, but Carl Brockelmann rejects this opinion.

Persian People
The Persians are an Iranian ethnic group who comprise over half of the population of Iran. They share a common cultural system and are native speakers of the Persian language as well as of the languages that are closely related to Persian. The ancient Persians were originally an ancient Iranian people who had migrated to the region of Persis (corresponding to the modern-day Iranian province of Fars) by the 9th century BCE. Together with their compatriot allies, they established and ruled some of the world's most powerful empires that are well-recognized for their massive cultural, political, and social influence, which covered much of the territory and population of the ancient world.. Throughout history, the Persian people have contributed greatly to art and science. Persian literature is one of the world's most prominent literary traditions. In contemporary terminology, people from Afghanistan, Tajikistan, and Uzbekistan who natively speak the Persian language are k ...

Ibn Al-A'rabi
Abū ʿAbd Allāh Muḥammad ibn Ziyād (), surnamed Ibn al-Aʿrābī () (ca. 760 – 846, Sāmarrā); a philologist, genealogist, and oral traditionist of Arabic tribal poetry. A grammarian of the school of al-Kūfah, who rivalled the grammarians of al-Baṣrah in poetry recital. He was famous for his knowledge of rare expressions and for transmitting the famous anthology of ancient Arabic poetry, '' Al-Mufaḍḍalīyāt''. The meaning of the word ''A'rābī'', and its difference to the word ''Arabī'', is explained by the exegete al-Sijistānī, in his book on rare Qur’ānic terms: ''A'rābī'' is a non-Arab desert inhabitant, whereas ''Arabī'' is a non-desert dwelling Arab. Life Ibn al-Aʿrābī was born in al-Kūfah in 760. His father, Ziyād, had been captured from Sindh, probably by the Banū Hāshim, or possibly by the Banū Shaybān or some other tribe. He himself was a ''mawla'' (client) of al-Abbās ibn Muḥammad ibn Alī ibn ʿAbd Allāh. He was said to h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
9th-century Iranian Astronomers
The 9th century was a period from 801 ( DCCCI) through 900 ( CM) in accordance with the Julian calendar. The Carolingian Renaissance and the Viking raids occurred within this period. In the Middle East, the House of Wisdom was founded in Abbasid Baghdad, attracting many scholars to the city. The field of algebra was founded by the Muslim polymath al-Khwarizmi. The most famous Islamic Scholar Ahmad ibn Hanbal was tortured and imprisoned by Abbasid official Ahmad ibn Abi Du'ad during the reign of Abbasid caliph al-Mu'tasim and caliph al-Wathiq. In Southeast Asia, the height of the Mataram Kingdom happened in this century, while Burma would see the establishment of the major kingdom of Pagan. Tang China started the century with the effective rule under Emperor Xianzong and ended the century with the Huang Chao rebellions. While the Maya experienced widespread political collapse in the central Maya region, resulting in internecine warfare, the abandonment of cities, and a nort ...

Year Of Birth Unknown
A year or annus is the orbital period of a planetary body, for example, the Earth, moving in its orbit around the Sun. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by change in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar climate, subpolar regions around the planet, four seasons are generally recognized: spring (season), spring, summer, autumn and winter. In tropics, tropical and subtropics, subtropical regions, several geographical sectors do not present defined seasons; but in the tropics#Seasons and climate, seasonal tropics, the annual wet season, wet and dry seasons are recognized and tracked. A calendar year is an approximation of the number of days of the Earth's orbital period, as counted in a given calendar. The Gregorian calendar, or modern calendar, presents its calendar year to be either a common year of 365 days or a leap year of 366 days, as do t ...

Carl Brockelmann
Carl Brockelmann (17 September 1868 – 6 May 1956) German Semiticist, was the foremost orientalist of his generation. He was a professor at the universities in Breslau, Berlin and, from 1903, Königsberg. He is best known for his multi-volume '' Geschichte der arabischen Litteratur'' (first published 1898–1902) ('History of Arabic literature') which included all writers in Arabic to 1937, and remains the fundamental reference volume for all Arabic literature, apart from the Christian Arabic texts (covered by Georg Graf). He also published ''Syrische Grammatik mit Litteratur, Chrestomathie und Glossar'' (1899), ''Semitische Sprachwissenschaft'' (1906), ''Lexicon syriacum'' (1928), and ''Arabische Grammatik'' (under his own name 1941, but this was the eleventh edition of the grammar of Albert Socin, previously revised by Brockelmann several times). Career Brockelmann pursued Oriental studies, classical philology, and history in Rostock, Breslau, and Strasburg. He earned his ...

George Sarton
George Alfred Leon Sarton (; 31 August 1884 – 22 March 1956) was a Belgian-born American chemist and historian. He is considered the founder of the discipline of the history of science as an independent field of study. His most influential works were the ''Introduction to the History of Science'', which consists of three volumes and 4,296 pages and the journal ''Isis''. Sarton ultimately aimed to achieve an integrated philosophy of science that provided a connection between the sciences and the humanities, which he referred to as "the new humanism". Sarton's life and work George Alfred Leon Sarton was born to Léonie Van Halmé and Alfred Sarton on August 31, 1884 in Ghent, East Flanders, Belgium. However, within a year of his birth, Sarton's mother died. He attended school first in his hometown before later attending school for a period of four years in the town of Chimay. Sarton enrolled at the University of Ghent in 1902 to study philosophy, but found that the subject did ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Meridian (geography)
In geography and geodesy, a meridian is the locus connecting points of equal longitude, which is the angle (in degrees or other units) east or west of a given prime meridian (currently, the IERS Reference Meridian). In other words, it is a line of longitude. The position of a point along the meridian is given by that longitude and its latitude, measured in angular degrees north or south of the Equator. On a Mercator projection or on a Gall-Peters projection, each meridian is perpendicular to all circles of latitude. A meridian is half of a great circle on Earth's surface. The length of a meridian on a modern ellipsoid model of Earth ( WGS 84) has been estimated as . Pre-Greenwich The first prime meridian was set by Eratosthenes in 200 BCE. This prime meridian was used to provide measurement of the earth, but had many problems because of the lack of latitude measurement. Many years later around the 19th century there were still concerns of the prime meridian. Mu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
