Jamshīd Al-Kāshī
Ghiyāth al-Dīn Jamshīd Masʿūd al-Kāshī (or al-Kāshānī) ( fa, غیاث الدین جمشید کاشانی ''Ghiyās-ud-dīn Jamshīd Kāshānī'') (c. 1380 Kashan, Iran – 22 June 1429 Samarkand, Transoxania) was a Persian astronomer and mathematician during the reign of Tamerlane. Much of al-Kāshī's work was not brought to Europe, and still, even the extant work, remains unpublished in any form. Biography Al-Kashi was born in 1380, in Kashan, in central Iran. This region was controlled by Tamerlane, better known as Timur. The situation changed for the better when Timur died in 1405, and his son, Shah Rokh, ascended into power. Shah Rokh and his wife, Goharshad, a Turkish princess, were very interested in the sciences, and they encouraged their court to study the various fields in great depth. Consequently, the period of their power became one of many scholarly accomplishments. This was the perfect environment for al-Kashi to begin his career as one of the worl ...

Mathematics In Medieval Islam
Mathematics during the Golden Age of Islam, especially during the 9th and 10th centuries, was built on Greek mathematics (Euclid, Archimedes, Apollonius of Perga, 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 language, 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 people, Greek mathematician Diophantus, known as the father of algebra.

Observatory
An observatory is a location used for observing terrestrial, marine, or celestial events. Astronomy, climatology/meteorology, geophysical, oceanography and volcanology are examples of disciplines for which observatories have been constructed. Historically, observatories were as simple as containing an astronomical sextant (for measuring the distance between stars) or Stonehenge (which has some alignments on astronomical phenomena). Astronomical observatories Astronomical observatories are mainly divided into four categories: space-based, airborne, ground-based, and underground-based. Ground-based observatories Ground-based observatories, located on the surface of Earth, are used to make observations in the radio and visible light portions of the electromagnetic spectrum. Most optical telescopes are housed within a dome or similar structure, to protect the delicate instruments from the elements. Telescope domes have a slit or other opening in the roof that can be opened during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Timurid Dynasty
The Timurid dynasty ( chg, , fa, ), self-designated as Gurkani ( chg, , translit=Küregen, fa, , translit=Gūrkāniyān), was a Sunni Muslim dynasty or clan of Turco-Mongol originB.F.

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 ...

Middle East
The Middle East ( ar, الشرق الأوسط, ISO 233: ) is a geopolitical region commonly encompassing Arabian Peninsula, Arabia (including the Arabian Peninsula and Bahrain), Anatolia, Asia Minor (Asian part of Turkey except Hatay Province), East Thrace (European part of Turkey), Egypt, Iran, the Levant (including Syria (region), Ash-Shām and Cyprus), Mesopotamia (modern-day Iraq), and the Socotra Governorate, Socotra Archipelago (a part of Yemen). The term came into widespread usage as a replacement of the term Near East (as opposed to the Far East) beginning in the early 20th century. The term "Middle East" has led to some confusion over its changing definitions, and has been viewed by some to be discriminatory or too Eurocentrism, Eurocentric. The region includes the vast majority of the territories included in the closely associated definition of Western Asia (including Iran), but without the South Caucasus, and additionally includes all of Egypt (not just the Sina ...

Sciences
Science is a systematic endeavor that builds and organizes knowledge in the form of testable explanations and predictions about the universe. Science may be as old as the human species, and some of the earliest archeological evidence for scientific reasoning is tens of thousands of years old. The earliest written records in the history of science come from Ancient Egypt and Mesopotamia in around 3000 to 1200 BCE. Their contributions to mathematics, astronomy, and medicine entered and shaped Greek natural philosophy of classical antiquity, whereby formal attempts were made to provide explanations of events in the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but was preserved in the Muslim world during the Islamic Golden Age and later by the efforts of Byzantine Greek scholars who brought Greek ...

Goharshad
Gawhar Shad ( fa, , Gawaršād; meaning "joyful jewel" or "shining jewel"; alternative spelling: Gohar Shād; died 19 July 1457) was the chief consort of Shah Rukh, the emperor of the Timurid Empire. Life She was the daughter of Giāth ud-Din Tarkhān, an important and influential noble during Tīmur's reign. According to family traditions, the title '' Tarkhān'' was given to the family by Genghis Khan personally. Marriage Gawhar Shad was married to Shah Rukh probably in 1388, certainly before 1394 when their son, Ulugh Beg was born. It was a successful marriage, according to the ballads of Herat which sing of Shah Rukh's love for her. But little is known of their first forty years together, except what concerns her buildings. Along with her brothers who were administrators at the Timurid court in Herat, Gawhar Shad played a very important role in the early Timurid history. In 1405 she moved the Timurid capital from Samarkand to Herat. She was instrumental in the constructi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shah Rukh (Timurid Dynasty)
Shah Rukh or Shahrukh ( fa, شاهرخ, ''Šāhrokh'') (20 August 1377 – 13 March 1447) was the ruler of the Timurid Empire between 1405 and 1447. He was the son of the Central Asian conqueror Timur (Tamerlane), who founded the Timurid dynasty in 1370. However, Shah Rukh ruled only over the eastern portion of the empire established by his father, comprising most of Persia and Transoxiana, the western territories having been lost to invaders in the aftermath of Timur's death. In spite of this, Shah Rukh's empire remained a cohesive dominion of considerable extent throughout his reign, as well as a dominant power in Asia. Shah Rukh controlled the main trade routes between Asia and Europe, including the legendary Silk Road, and became immensely wealthy as a result. He chose to have his capital not in Samarqand as his father had done, but in Herat. This was to become the political centre of the Timurid empire and residence of his principal successors, though both cities benefited ...
