Inventions In Medieval Islam
The following is a list of inventions, discoveries and scientific advancements made in the medieval Muslim world, Islamic world, especially during the Islamic Golden Age,George Saliba (1994), ''A History of Arabic Astronomy: Planetary Theories During the Golden Age of Islam'', pp. 245, 250, 256–57. New York University Press, . as well as in later states of the Age of the Islamic Gunpowders such as the Ottoman Empire, Ottoman and Mughal Empire, Mughal empires. The Islamic Golden Age was a period of cultural, economic and scientific flourishing in the history of Islam, traditionally dated from the eighth century to the fourteenth century, with several contemporary scholars dating the end of the era to the fifteenth or sixteenth century. This period is traditionally understood to have begun during the reign of the Abbasid Caliphate, Abbasid caliph Harun al-Rashid (786 to 809) with the inauguration of the House of Wisdom in Baghdad, where scholars from various parts of the world wi ...

Ghazal
''Ghazal'' is a form of amatory poem or ode, originating in Arabic poetry that often deals with topics of spiritual and romantic love. It may be understood as a poetic expression of both the pain of loss, or separation from the beloved, and the beauty of love in spite of that pain. The ghazal form is ancient, tracing its origins to 7th-century Arabic poetry. It spread into the Indian subcontinent in the 12th century due to the influence of Sufi mystics and the courts of the new Ghurid Sultanate, Islamic Sultanate, and is now most prominently a form of poetry of many languages of South Asia and Languages of Turkey, Turkey. A poem of ghazal commonly consists of five to fifteen couplets, which are independent, but are linked – abstractly, in their theme; and more strictly in their poetic form. The structural requirements of ghazal are similar in stringency to those of the Petrarchan sonnet. In style and content, due to its highly allusive nature, ghazal has proved capable of a ...

Muhammad Ibn Zakariya Al-Razi
Abū Bakr al-Rāzī, also known as Rhazes (full name: ), , was a Persian physician, philosopher and alchemist who lived during the Islamic Golden Age. He is widely regarded as one of the most important figures in the history of medicine, and also wrote on logic, astronomy and grammar. He is also known for his criticism of religion, especially with regard to the concepts of prophethood and revelation. However, the religio-philosophical aspects of his thought, which also included a belief in five "eternal principles", are fragmentary and only reported by authors who were often hostile to him. A comprehensive thinker, al-Razi made fundamental and enduring contributions to various fields, which he recorded in over 200 manuscripts, and is particularly remembered for numerous advances in medicine through his observations and discoveries. An early proponent of experimental medicine, he became a successful doctor, and served as chief physician of Baghdad and Ray hospitals.. As a te ...

Jabir Ibn Hayyan
Abū Mūsā Jābir ibn Ḥayyān (Arabic: , variously called al-Ṣūfī, al-Azdī, al-Kūfī, or al-Ṭūsī), died 806−816, is the purported author of a large number of works in Arabic, often called the Jabirian corpus. The treatises that survive today mainly deal with alchemy and chemistry, magic, and Shi'ite religious philosophy. However, the original scope of the corpus was vast, covering a wide range of topics ranging from cosmology, astronomy and astrology, over medicine, pharmacology, zoology and botany, to metaphysics, logic, and grammar. The works attributed to Jabir, which are tentatively dated to , contain the oldest known systematic classification of chemical substances, and the oldest known instructions for deriving an inorganic compound ( sal ammoniac or ammonium chloride) from organic substances (such as plants, blood, and hair) by chemical means. His works also contain one of the earliest known versions of the sulfur-mercury theory of metals, a mineralo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemical Substance
A chemical substance is a unique form of matter with constant chemical composition and characteristic properties. Chemical substances may take the form of a single element or chemical compounds. If two or more chemical substances can be combined without reacting, they may form a chemical mixture. If a mixture is separated to isolate one chemical substance to a desired degree, the resulting substance is said to be chemically pure. Chemical substances can exist in several different physical states or phases (e.g. solids, liquids, gases, or plasma) without changing their chemical composition. Substances transition between these phases of matter in response to changes in temperature or pressure. Some chemical substances can be combined or converted into new substances by means of chemical reactions. Chemicals that do not possess this ability are said to be inert. Pure water is an example of a chemical substance, with a constant composition of two hydrogen atoms bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Princeton University Press
Princeton University Press is an independent publisher with close connections to Princeton University. Its mission is to disseminate scholarship within academia and society at large. The press was founded by Whitney Darrow, with the financial support of Charles Scribner, as a printing press to serve the Princeton community in 1905. Its distinctive building was constructed in 1911 on William Street in Princeton. Its first book was a new 1912 edition of John Witherspoon's ''Lectures on Moral Philosophy.'' History Princeton University Press was founded in 1905 by a recent Princeton graduate, Whitney Darrow, with financial support from another Princetonian, Charles Scribner II. Darrow and Scribner purchased the equipment and assumed the operations of two already existing local publishers, that of the ''Princeton Alumni Weekly'' and the Princeton Press. The new press printed both local newspapers, university documents, '' The Daily Princetonian'', and later added book publishing ...

Horizon
The horizon is the apparent curve that separates the surface of a celestial body from its sky when viewed from the perspective of an observer on or near the surface of the relevant body. This curve divides all viewing directions based on whether it intersects the relevant body's surface or not. The ''true horizon'' is a theoretical line, which can only be observed to any degree of accuracy when it lies along a relatively smooth surface such as that of Earth's oceans. At many locations, this line is obscured by terrain, and on Earth it can also be obscured by life forms such as trees and/or human constructs such as buildings. The resulting intersection of such obstructions with the sky is called the ''visible horizon''. On Earth, when looking at a sea from a shore, the part of the sea closest to the horizon is called the offing. Pronounced, "Hor-I-zon". The true horizon surrounds the observer and it is typically assumed to be a circle, drawn on the surface of a perfectly sph ...

Azimuth
An azimuth (; from ) is the horizontal angle from a cardinal direction, most commonly north, in a local or observer-centric spherical coordinate system. Mathematically, the relative position vector from an observer ( origin) to a point of interest is projected perpendicularly onto a reference plane (the horizontal plane); the angle between the projected vector and a reference vector on the reference plane is called the azimuth. When used as a celestial coordinate, the azimuth is the horizontal direction of a star or other astronomical object in the sky. The star is the point of interest, the reference plane is the local area (e.g. a circular area with a 5 km radius at sea level) around an observer on Earth's surface, and the reference vector points to true north. The azimuth is the angle between the north vector and the star's vector on the horizontal plane. Azimuth is usually measured in degrees (°), in the positive range 0° to 360° or in the signed ...

Astronomy In Medieval Islam
Medieval Islamic astronomy comprises the Astronomy, astronomical developments made in the Islamic world, particularly during the Islamic Golden Age (9th–13th centuries), and mostly written in the Arabic language. These developments mostly took place in the Middle East, Central Asia, Al-Andalus, and North Africa, and later in the Far East and History of India, India. It closely parallels the genesis of other Islamic sciences in its assimilation of foreign material and the amalgamation of the disparate elements of that material to create a science with Islamic characteristics. These included Greek astronomy, Greek, Sassanid Empire, Sassanid, and Indian astronomy, Indian works in particular, which were translated and built upon. Islamic astronomy played a significant role in the revival of ancient astronomy following the Dark Ages (historiography), loss of knowledge during the early medieval period, notably with the production of Middle Latin, Latin translations of Arabic works La ...

Astrolabe
An astrolabe (; ; ) is an astronomy, astronomical list of astronomical instruments, instrument dating to ancient times. It serves as a star chart and Model#Physical model, physical model of the visible celestial sphere, half-dome of the sky. Its various functions also make it an elaborate inclinometer and an analog computer, analog calculation device capable of working out several kinds of problems in astronomy. In its simplest form it is a metal disc with a pattern of wires, cutouts, and perforations that allows a user to calculate astronomical positions precisely. It is able to measure the horizontal coordinate system, altitude above the horizon of a celestial body, day or night; it can be used to identify stars or planets, to determine local latitude given local time (and vice versa), to survey, or to triangulation, triangulate. It was used in classical antiquity, the Islamic Golden Age, the European Middle Ages and the Age of Discovery for all these purposes. The astrolabe, ...

Mshatta Facade
The Mshatta Facade is the decorated part of the facade of the 8th-century Umayyad residential palace of Qasr Mshatta, one of the Desert Castles of Jordan, which is now installed in the south wing of the Pergamon Museum in Berlin, Germany. It is part of the permanent exhibition of the Pergamon Museum of Islamic Art dedicated to Islamic art from the 8th to the 19th centuries. This was only a relatively small section of the full length of the facade, surrounding the main entrance; most of the wall was undecorated and remains ''in situ''. History The facade belonged to the Qasr Mshatta or Mshatta palace, which was excavated about 30 km south of the contemporary Jordanian capital of Amman. It is thought to have served as a winter residence and storage halls during the Umayyad period. The building of the palace probably dates to the era of the caliph Al-Walid II (743-744). After Al Walid was murdered, it was left incomplete and later ruined in an earthquake. The sections of the out ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arabesque
The arabesque is a form of artistic decoration consisting of "surface decorations based on rhythmic linear patterns of scrolling and interlacing foliage, tendrils" or plain lines, often combined with other elements. Another definition is "Foliate ornament, used in the Islamic world, typically using leaves, derived from stylised half-palmettes, which were combined with spiralling stems". It usually consists of a single design which can be ' tiled' or seamlessly repeated as many times as desired. Within the very wide range of Eurasian decorative art that includes motifs matching this basic definition, the term "arabesque" is used consistently as a technical term by art historians to describe only elements of the decoration found in two phases: Islamic art from about the 9th century onwards, and European decorative art from the Renaissance onwards. Interlace and scroll decoration are terms used for most other types of similar patterns. Arabesques are a fundamental element of Isla ...
