The couple was first proposed by the 13th-century Persian astronomer and mathematician Nasir al-Din al-Tusi in his 1247 Tahrir al-Majisti (Commentary on the Almagest) as a solution for the latitudinal motion of the inferior planets [4] and later used extensively as a substitute for the equant introduced over a thousand years earlier in Ptolemy ...
The Tusi couple, a mathematical device invented by the Persian polymath Nasir al-Din Tusi to model the not perfectly circular motions of the planets. Science in the medieval Islamic world was the science developed and practised during the Islamic Golden Age under the Abbasid Caliphate of Baghdad, the Umayyads of Córdoba, the Abbadids of Seville, the Samanids, the Ziyarids and the Buyids in ...
Al-Kindi, pioneer of environmental science [29] Zakariya al-Qazwini (1204-1283), geographer, cozmographer, physicist and mathematician. He explained the formation of mountains and collected the latitude, longitude and climate of 700 cities together with their time differences in a book.
After al-Tusi's death, his son Sadr al-Din succeeded him as director of the observatory. [2] During Uljaytu's reign, he appointed al-Tusi's other son, 'Asil al-Din as director. [2] [11] Scholars and students of mathematics, science, and astronomy came to the Maragheh Observatory from across the Islamic world and up to the eastern borders of ...
The spherical law of sines was discovered in the 10th century: it has been attributed variously to Abu-Mahmud Khojandi, Nasir al-Din al-Tusi and Abu Nasr Mansur, with Abu al-Wafa' Buzjani as a contributor. [16] Ibn Muʿādh al-Jayyānī's The book of unknown arcs of a sphere in the 11th century introduced the general law of sines. [23]
In the 13th century, Nasir al-Din Tusi (Nasireddin) made advances in spherical trigonometry. He also wrote influential work on Euclid's parallel postulate. In the 15th century, Ghiyath al-Kashi computed the value of π to the 16th decimal place.
Another notable work from Nasir al-Din al-Tusi was an astronomical book that contained detailed notes and observations about the movement of planets. Under Nasir al-Din al-Tusi, scholars from across the Islamic world came to the Maragheh observatory in order to further their studies in math, science, and astronomy.
