Nasīr Al-Dīn Al-Tūsī
Muḥammad ibn Muḥammad ibn al-Ḥasan al-Ṭūsī (1201 – 1274), also known as Naṣīr al-Dīn al-Ṭūsī (; ) or simply as (al-)Tusi, 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 scholar Ibn Khaldun (1332–1406) considered Tusi to be the greatest of the later Persian scholars.James Wins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Islam
Islam is an Abrahamic religions, Abrahamic monotheistic religion based on the Quran, and the teachings of Muhammad. Adherents of Islam are called Muslims, who are estimated to number Islam by country, 2 billion worldwide and are the world's Major religious groups, second-largest religious population after Christians. Muslims believe that Islam is the complete and universal version of a Fitra, primordial faith that was revealed many times through earlier Prophets and messengers in Islam, prophets and messengers, including Adam in Islam, Adam, Noah in Islam, Noah, Abraham in Islam, Abraham, Moses in Islam, Moses, and Jesus in Islam, Jesus. Muslims consider the Quran to be the verbatim word of God in Islam, God and the unaltered, final revelation. Alongside the Quran, Muslims also believe in previous Islamic holy books, revelations, such as the Torah in Islam, Tawrat (the Torah), the Zabur (Psalms), and the Gospel in Islam, Injil (Gospel). They believe that Muhammad in Islam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ja'fari
The Jaʿfarī school, also known as the Jafarite school, Jaʿfarī fiqh () or Ja'fari jurisprudence, is a prominent school of jurisprudence (''fiqh'') within Twelver and Ismaili (including Nizari) Shia Islam, named after the sixth Imam, Ja'far al-Sadiq. In Iran, Jaʽfari jurisprudence is enshrined in the constitution, shaping various aspects of governance, legislation, and judiciary in the country. In Lebanon this school of jurispudence is also accounted for in the sectarian legal system of the country and Shia muslims can call upon it for their legal disputes. It differs from the predominant madhhabs of Sunni jurisprudence in its reliance on ''ijtihad'', as well as on matters of inheritance, religious taxes, commerce, personal status, and the allowing of temporary marriage or '' mutʿa''. Since 1959, Jaʿfari jurisprudence has been afforded the status of "fifth school" along with the four Sunni schools by Azhar University. In addition, it is one of the eight recognized ''madh ...

Kamal Al-Din Ibn Yunus
Kamāl al-Dīn ibn Yūnus (1156–1242) was an Iraqi Muslim polymath known for his writings on mathematics, although he also studied and taught astronomy, theology, philology, law, philosophy and medicine. For many years he taught Muslim, Christian and Jewish pupils at his own school in his native city of Mosul. Life A biography of Ibn Yūnus appears in the of Ibn Abī Uṣaybiʿa. An even longer one is found in the of Ibn Khallikān, whose father was a friend of Ibn Yūnus. Ibn Abī Uṣaybiʿa gives his as Abū ʿImrān, while Ibn Khallikān gives it as Abū al-Fatḥ. Kamāl al-Dīn was his , while his given name was Mūsā and his (patronymic) was ibn Yūnus ibn Muḥammad ibn Manʿat. Ibn Yūnus was born in Mosul and studied in Baghdad.

Akhlaq-i Nasiri
''Nasirean Ethics'' () is a 13th-century Persian book in philosophical ethics that is written by Khaje Nasir al-Din al-Tusi. This book is divided to three part: ethics, domestic economy and politics. Author Nasir al-Din al-Tusi was Persian philosopher, mathematician, and theologian that was born into Shia family in Tus in 1201. He was of the Ismaili, and subsequently Twelver Shia Islamic belief. Nasir al-Din has about 150 works in different languages (Persian, Arabic).H. Daiber, F.J. Ragep, "Tusi" in Encyclopaedia of Islam. Edited by: P. Bearman, Th. Bianquis, C.E. Bosworth, E. van Donzel and W.P. Heinrichs. Brill, 2007. Brill Online. Quote: "Tusi's prose writings, which number over 150 works, represent one of the largest collections by a single Islamic author. Writing in both Arabic and Persian, Nasir al-Din dealt with both religious ("Islamic") topics and non-religious or secular subjects ("the ancient sciences")."Seyyed Hossein Nasr.

Zij-i Ilkhani
''Zīj-i Īlkhānī'' () or ''Ilkhanic Tables'' (literal translation: "The Ilkhan Stars", after ilkhan Hulagu, who was the patron of the author at that time) is a ''Zij'' book with Ephemeris, astronomical tables of planetary movements. It was compiled by the Muslims, Muslim astronomer Nasir al-Din al-Tusi in collaboration with his research team of astronomers at the Maragha observatory. It was written in Persian language, Persian and later translated into Arabic language, Arabic. The book contains tables for calculating the positions of the planets and the names of the stars. It included data derived from the observations made over the course of 12 years in the Maragha observatory, completed in 1272. The planetary positions of the Zij-i Ilkhani, derived from the zijs of Ibn al-A'lam and Ibn Yunus (10/11th cent. AD), were so faulty that later astronomers, such as al-Wabkanawi and Rukn al-Din al-Amuli, criticized it severely. The ''Zīj-i Īlkhānī'' set the Axial precession, pre ...

Tusi Couple
The Tusi couple (also known as Tusi's mechanism) is a mathematical device in which a small circle rotates inside a larger circle twice the diameter of the smaller circle. Rotations of the circles cause a point on the circumference of the smaller circle to Oscillation (mathematics), oscillate back and forth in linear motion along a diameter of the larger circle. The Tusi couple is a two-cusped hypocycloid. The couple was first proposed by the 13th-century Persian people, Persian Islamic astronomy, astronomer and Islamic mathematics, 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 and later used extensively as a substitute for the equant introduced over a thousand years earlier in Ptolemy's ''Almagest''. Original description The translation of the copy of Tusi's original description of his geometrical model alludes to at least one inversion of the model to b ...

Spherical Trigonometry
Spherical trigonometry is the branch of spherical geometry that deals with the metrical relationships between the edge (geometry), sides and angles of spherical triangles, traditionally expressed using trigonometric functions. On the sphere, geodesics are great circles. Spherical trigonometry is of great importance for calculations in astronomy, geodesy, and navigation. The origins of spherical trigonometry in Greek mathematics and the major developments in Islamic mathematics are discussed fully in History of trigonometry and Mathematics in medieval Islam. The subject came to fruition in Early Modern times with important developments by John Napier, Jean Baptiste Joseph Delambre, Delambre and others, and attained an essentially complete form by the end of the nineteenth century with the publication of Todhunter's textbook ''Spherical trigonometry for the use of colleges and Schools''. Since then, significant developments have been the application of vector methods, quaternion m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Islamic Science
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 Persia and beyond, spanning the period roughly between 786 and 1258. Islamic scientific achievements encompassed a wide range of subject areas, especially astronomy, mathematics, and medicine. Other subjects of scientific inquiry included alchemy and chemistry, botany and agronomy, geography and cartography, ophthalmology, pharmacology, physics, and zoology. Medieval Islamic science had practical purposes as well as the goal of understanding. For example, astronomy was useful for determining the ''Qibla'', the direction in which to pray, botany had practical application in agriculture, as in the works of Ibn Bassal and Ibn al-'Awwam, and geography enabled Abu Zayd al-Balkhi to make accurate maps. Islamic mathematicians such as Al-K ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Islamic Physics
The natural sciences saw various advancements during the Golden Age of Islam (from roughly the mid 8th to the mid 13th centuries), adding a number of innovations to the Transmission of the Classics (such as Aristotle, Ptolemy, Euclid, Neoplatonism).''Classical Arabic Philosophy An Anthology of Sources'', Translated by Jon McGinnis and David C. Reisman. Indianapolis: Hackett Publishing Company, 2007. pg. xix During this period, Islamic theology was encouraging of thinkers to find knowledge. Thinkers from this period included Al-Farabi, Abu Bishr Matta, Ibn Sina, al-Hassan Ibn al-Haytham and Ibn Bajjah. These works and the important commentaries on them were the wellspring of science during the medieval period. They were translated into Arabic, the ''lingua franca'' of this period. Islamic scholarship in the sciences had inherited Aristotelian physics from the Greeks and during the Islamic Golden Age developed it further. However the Islamic world had a greater respect for k ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Islamic Medicine
In the history of medicine, "Islamic medicine", also known as "Arabian medicine" is the science of medicine developed in the Middle East, and usually written in Arabic, the ''lingua franca'' of Islamic civilization. Islamic medicine adopted, systematized and developed the medical knowledge of classical antiquity, including the major traditions of Hippocrates, Galen and Dioscorides. During the post-classical era, Middle Eastern medicine was the most advanced in the world, integrating concepts of Modern Greek, Roman, Mesopotamian and Persian medicine as well as the ancient Indian tradition of Ayurveda, while making numerous advances and innovations. Islamic medicine, along with knowledge of classical medicine, was later adopted in the medieval medicine of Western Europe, after European physicians became familiar with Islamic medical authors during the Renaissance of the 12th century. Medieval Islamic physicians largely retained their authority until the rise of medicine as a p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Islamic Mathematics
Mathematics during the Golden Age of Islam, especially during the 9th and 10th centuries, was built upon syntheses of Greek mathematics (Euclid, Archimedes, Apollonius) and Indian mathematics (Aryabhata, Brahmagupta). Important developments of the period include extension of the place-value system to include decimal fractions, the systematised study of algebra and advances in geometry and trigonometry. The medieval Islamic world underwent significant developments in mathematics. Muhammad ibn Musa al-Khwārizmī played a key role in this transformation, introducing algebra as a distinct field in the 9th century. Al-Khwārizmī's approach, departing from earlier arithmetical traditions, laid the groundwork for the arithmetization of algebra, influencing mathematical thought for an extended period. Successors like Al-Karaji expanded on his work, contributing to advancements in various mathematical domains. The practicality and broad applicability of these mathematical methods ...
