Shams Al-Din Al-Samarqandi
(c. 1250 – c. 1310) was a 13th-century astronomer and mathematician from Samarkand. Life and works Nothing is known of al-Samarqandi's life except that he composed his most important works in the last two decades of the 7th and early decades of the 8th centuries A.H. He wrote works on theology, logic, philosophy, mathematics and astronomy which have proved important in their own right and also in giving information about the works of other scientists of his period. Al-Samarqandi wrote a work ''Risala fi adab al-bahth'' which discussed the method of intellectual investigation of reasoning using dialectic. Such methods of enquiry were much used by the ancient Greeks. He also wrote ''Synopsis of Astronomy'', and produced a star catalogue for the year 1276–77. In mathematics, al-Samarqandi is famous for a short work of only 20 pages which discusses 35 of Euclid's propositions. Although a short work, al-Samarqandi consulted widely the works of other Muslim mathematicians before ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astronomer
An astronomer is a scientist in the field of astronomy who focuses their studies on a specific question or field outside the scope of Earth. They observe astronomical objects such as stars, planets, natural satellite, moons, comets and galaxy, galaxies – in either observational astronomy, observational (by analyzing the data) or theoretical astronomy. Examples of topics or fields astronomers study include planetary science, Sun, solar astronomy, the Star formation, origin or stellar evolution, evolution of stars, or the galaxy formation and evolution, formation of galaxies. A related but distinct subject is physical cosmology, which studies the Universe as a whole. Types Astronomers usually fall under either of two main types: observational astronomy, observational and theoretical astronomy, theoretical. Observational astronomers make direct observations of Astronomical object, celestial objects and analyze the data. In contrast, theoretical astronomers create and investigate C ...

Athīr Al-Dīn Al-Abharī
Athīr al‐Dīn al‐Mufaḍḍal ibn ʿUmar ibn al‐Mufaḍḍal al‐Samarqandī al‐Abharī, also known as Athīr al‐Dīn al‐Munajjim (d. in 1265 or 1262 Shabestar, Iran) was an Iranian muslim polymath, philosopher, astronomer, astrologer and mathematician. Other than his influential writings, he had many famous disciples. Life His birthplace is contested among sources. According to Encyclopedia of Islam and Encyclopedia Islamica, he was born in Abhar, a small town between Qazvin and Zanjan. Encyclopedia Iranica mentions that he was born in Mosul, but according to Encyclopedia Islamica, none of his oldest biographers mentioned Mosul as his birthplace. Beside the city of Abhar, his epithet al-Abharī could suggest that he or his ancestors originally stem from the Abhar tribe. He may have died of paralysis in Adharbayjan. He is said to have been a student or teacher in various schools at Khurāsān, Baghdad, and Arbil, living for some time in Sivas. Ibn Khallik ...

14th-century Iranian People
As a means of recording the passage of time, the 14th century was a century lasting from 1 January 1301 ( MCCCI), to 31 December 1400 ( MCD). It is estimated that the century witnessed the death of more than 45 million lives from political and natural disasters in both Europe and the Mongol Empire. West Africa experienced economic growth and prosperity. In Europe, the Black Death claimed 25 million lives wiping out one third of the European population while the Kingdom of England and the Kingdom of France fought in the protracted Hundred Years' War after the death of Charles IV, King of France led to a claim to the French throne by Edward III, King of England. This period is considered the height of chivalry and marks the beginning of strong separate identities for both England and France as well as the foundation of the Italian Renaissance and Ottoman Empire. In Asia, Tamerlane (Timur), established the Timurid Empire, history's third largest empire to have been ever establish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
13th-century Astronomers
The 13th century was the century which lasted from January 1, 1201 ( MCCI) through December 31, 1300 ( MCCC) in accordance with the Julian calendar. The Mongol Empire was founded by Genghis Khan, which stretched from Eastern Asia to Eastern Europe. The conquests of Hulagu Khan and other Mongol invasions changed the course of the Muslim world, most notably the Siege of Baghdad (1258), the destruction of the House of Wisdom and the weakening of the Mamluks and Rums which, according to historians, caused the decline of the Islamic Golden Age. Other Muslim powers such as the Mali Empire and Delhi Sultanate conquered large parts of West Africa and the Indian subcontinent, while Buddhism witnessed a decline through the conquest led by Bakhtiyar Khilji. The Southern Song dynasty would begin the century as a prosperous kingdom but would eventually be invaded and annexed into the Yuan dynasty of the Mongols. The Kamakura Shogunate of Japan would be invaded by the Mongols. Goryeo resiste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mathematicians Of The Medieval Islamic World
A mathematician is someone who uses an extensive knowledge of mathematics in their work, typically to solve mathematical problems. Mathematicians are concerned with numbers, data, quantity, structure, space, models, and change. History One of the earliest known mathematicians were Thales of Miletus (c. 624–c.546 BC); he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed. He is credited with the first use of deductive reasoning applied to geometry, by deriving four corollaries to Thales' Theorem. The number of known mathematicians grew when Pythagoras of Samos (c. 582–c. 507 BC) established the Pythagorean School, whose doctrine it was that mathematics ruled the universe and whose motto was "All is number". It was the Pythagoreans who coined the term "mathematics", and with whom the study of mathematics for its own sake begins. The first woman mathematician recorded by history was Hypatia ...

Central Asia
Central Asia, also known as Middle Asia, is a subregion, region of Asia that stretches from the Caspian Sea in the west to western China and Mongolia in the east, and from Afghanistan and Iran in the south to Russia in the north. It includes the former Soviet Union, Soviet republics of the Soviet Union, republics of Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan, which are colloquially referred to as the "-stans" as the countries all have names ending with the Persian language, Persian suffix "-stan", meaning "land of". The current geographical location of Central Asia was formerly part of the historic region of Turkestan, Turkistan, also known as Turan. In the pre-Islamic and early Islamic eras ( and earlier) Central Asia was inhabited predominantly by Iranian peoples, populated by Eastern Iranian languages, Eastern Iranian-speaking Bactrians, Sogdians, Khwarezmian language, Chorasmians and the semi-nomadic Scythians and Dahae. After expansion by Turkic peop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1250 Births
1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maturidis
Māturīdī theology or Māturīdism ( ar, الماتريدية: ''al-Māturīdiyyah'') is one of the main Sunnī schools of Islamic theology, founded by the Persian Muslim scholar, Ḥanafī jurist, reformer (''Mujaddid''), and scholastic theologian Abū Manṣūr al-Māturīdī in the 9th–10th century. Al-Māturīdī codified and systematized the theological beliefs already present among the Ḥanafite Muslim theologians of Balkh and Transoxania under one school of systematic theology (''kalām''); he emphasized the use of rationality and theological rationalism regarding the interpretation of the sacred scriptures of Islam. Māturīdī theology is considered one of the orthodox creeds of Sunnī Islam alongside the Aṯharī and Ashʿarī, and prevails in the Ḥanafī school of Islamic jurisprudence. Māturīdism was originally circumscribed to the region of Transoxania in Central Asia but it became the predominant theological orientation amongst the Sunnī Muslim ...

Hanafis
The Hanafi school ( ar, حَنَفِية, translit=Ḥanafiyah; also called Hanafite in English), Hanafism, or the Hanafi fiqh, is the oldest and one of the four traditional major Sunni schools (maddhab) of Islamic Law (Fiqh). It is named after the 8th century Kufan scholar, Abu Hanifa, a Tabi‘i of Persian origin whose legal views were preserved primarily by his two most important disciples, Imam Abu Yusuf and Muhammad al-Shaybani. It is considered one of the most widely accepted maddhab amongst Sunni Muslim community and is called the ''Madhhab of Jurists'' (maddhab ahl al-ray). The importance of this maddhab lies in the fact that it is not just a collection of rulings or sayings of Imam Abu Hanifa alone, but rather the rulings and sayings of the council of judges he established belong to it. It had a great excellence and advantage over the establishment of Sunni Islamic legal science. No one before Abu Hanifa preceded in such works. He was the first to solve the cases and ...

Nasir Al-Din Al-Tusi
Muhammad ibn Muhammad ibn al-Hasan al-Tūsī ( fa, محمد ابن محمد ابن حسن طوسی 18 February 1201 – 26 June 1274), better known as Nasir al-Din al-Tusi ( fa, نصیر الدین طوسی, links=no; or simply Tusi in the West), was a Persian polymath, architect, philosopher, physician, scientist, and theologian. Nasir al-Din al-Tusi was a well published author, writing on subjects of math, engineering, prose, and mysticism. Additionally, al-Tusi made several scientific advancements. In astronomy, al-Tusi created very accurate tables of planetary motion, an updated planetary model, and critiques of Ptolemaic astronomy. He also made strides in logic, mathematics but especially trigonometry, biology, and chemistry. Nasir al-Din al-Tusi left behind a great legacy as well. Tusi is widely regarded as one of the greatest scientists of medieval Islam, since he is often considered the creator of trigonometry as a mathematical discipline in its own right. The Muslim sch ...
