Al-Zarqall
Abū Isḥāq Ibrāhīm ibn Yaḥyā al-Naqqāsh al-Zarqālī al-Tujibi (); also known as Al-Zarkali or Ibn Zarqala (1029–1100), was an Arab maker of astronomical instruments and an astrologer from the western part of the Islamic world. Although his name is conventionally given as al-Zarqālī, it is probable that the correct form was al-Zarqālluh.s.v. "al-Zarqālī", Julio Samsó, Encyclopaedia of Islam, New edition, vol. 11, 2002. In Latin he was referred to as Arzachel or Arsechieles, a modified form of ''Arzachel'', meaning 'the engraver'. He lived in Toledo, Al-Andalus before moving to Córdoba later in his life. His works inspired a generation of Islamic astronomers in Al-Andalus, and later, after being translated, were very influential in Europe. His invention of the Saphaea (a perfected astrolabe) proved very popular and was widely used by navigators until the 16th century. The crater Arzachel on the Moon is named after him.

Moon
The Moon is Earth's only natural satellite. It Orbit of the Moon, orbits around Earth at Lunar distance, an average distance of (; about 30 times Earth diameter, Earth's diameter). The Moon rotation, rotates, with a rotation period (lunar day) that is synchronized to its orbital period (Lunar month#Synodic month, lunar month) of 29.5 Earth days. This is the product of Earth's gravitation having tidal forces, tidally pulled on the Moon until one part of it stopped rotating away from the near side of the Moon, near side, making always the same lunar surface face Earth. Conversley, the gravitational pull of the Moon, on Earth, is the main driver of Earth's tides. In geophysical definition of planet, geophysical terms, the Moon is a planetary-mass object or satellite planet. Its mass is 1.2% that of the Earth, and its diameter is , roughly one-quarter of Earth's (about as wide as the contiguous United States). Within the Solar System, it is the List of Solar System objects by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ibn Bajjah
Abū Bakr Muḥammad ibn Yaḥyà ibn aṣ-Ṣā’igh at-Tūjībī ibn Bājja (), known simply as Ibn Bajja () or his Latinized name Avempace (; – 1138), was an Arab polymath, whose writings include works regarding astronomy, physics, and music, as well as philosophy, medicine, botany, and poetry. He was the author of the ''Kitāb an-Nabāt'' ("The Book of Plants"), a popular work on botany, which defined the sex of plants. His philosophical theories influenced the work of Ibn Rushd (Averroes) and Albertus Magnus. Most of his writings and books were not completed (or well-organized) due to his early death. He had a vast knowledge of medicine, mathematics, and astronomy. His main contribution to Islamic philosophy was his idea on soul phenomenology, which was never completed. Avempace was, in his time, not only a prominent figure of philosophy but also of music and poetry. His '' diwan'' (Arabic: collection of poetry) was rediscovered in 1951. Though many of his ...

Moorish
The term Moor is an exonym used in European languages to designate the Muslim populations of North Africa (the Maghreb) and the Iberian Peninsula (particularly al-Andalus) during the Middle Ages. Moors are not a single, distinct or self-defined people. Europeans of the Middle Ages and the early modern period variously applied the name to Arabs, Berbers, and Muslim Europeans. The term has been used in a broader sense to refer to Muslims in general,Menocal, María Rosa (2002).

Little, Brown, & Co. , p. 241 especially those of Arab or Berber descent, whether living in al-Andalus or North Africa. The 1911 ''Encyclopædia Britannica'' observed that the term had "no real ethnological value." The word has racial connotations and it has fallen out of fashion among scholars since the mid-20th century. The word is also used when denoting various other specific ethnic groups i ...

He has been called the "father of English literature", or, alternatively, the "father of English poetry". He was the first writer to be buried in what has since come to be called Poets' Corner, in Westminster Abbey. Chaucer also gained fame as a philosopher and astronomer, composing the scientific ''A Treatise on the Astrolabe'' for his 10-year-old son, Lewis.

Islamic Astronomy
Medieval Islamic astronomy comprises the 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 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, Sassanid, and Indian works in particular, which were translated and built upon. Islamic astronomy played a significant role in the revival of ancient astronomy following the loss of knowledge during the early medieval period, notably with the production of Latin translations of Arabic works during the 12th century. A significant number of stars in the sky, such as Aldebaran, Altair and Deneb, and astrono ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astronomy
Astronomy is a natural science that studies celestial objects and the phenomena that occur in the cosmos. It uses mathematics, physics, and chemistry in order to explain their origin and their overall evolution. Objects of interest include planets, natural satellite, moons, stars, nebulae, galaxy, galaxies, meteoroids, asteroids, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond atmosphere of Earth, Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole.

Geometry
Geometry (; ) is a branch of mathematics concerned with properties of space such as the distance, shape, size, and relative position of figures. Geometry is, along with arithmetic, one of the oldest branches of mathematics. A mathematician who works in the field of geometry is called a ''List of geometers, geometer''. Until the 19th century, geometry was almost exclusively devoted to Euclidean geometry, which includes the notions of point (geometry), point, line (geometry), line, plane (geometry), plane, distance, angle, surface (mathematics), surface, and curve, as fundamental concepts. Originally developed to model the physical world, geometry has applications in almost all sciences, and also in art, architecture, and other activities that are related to graphics. Geometry also has applications in areas of mathematics that are apparently unrelated. For example, methods of algebraic geometry are fundamental in Wiles's proof of Fermat's Last Theorem, Wiles's proof of Fermat's ...

Metalsmith
A metalsmith or simply smith is a craftsperson fashioning useful items (for example, tools, kitchenware, tableware, jewelry, armor and weapons) out of various metals. Smithing is one of the oldest list of metalworking occupations, metalworking occupations. Shaping metal with a hammer (forging) is the archetypical component of smithing. Often the hammering is done while the metal is hot, having been heated in a forge. Smithing can also involve the other aspects of metalworking, such as refining metals from their ores (traditionally done by smelting), casting it into shapes (foundry, founding), and file (tool), filing to shape and size. The prevalence of metalworking in the culture of recent centuries has led ''Smith (surname), Smith'' and its equivalents in various languages to be a common surname#Occupational name, occupational surname (German Schmidt (surname), Schmidt or Schmied, Portuguese Ferreiro, Ferreira (surname), Ferreira, French Lefèvre, Spanish Herrero, Italian Fabbri ...

It was established in 1023 and lasted until 1091, in what is today southern Spain and Portugal. It gained independence from the Caliphate of Cordoba and it expanded the territory it ruled in the mid-11th century. The emerging power of Castile led Seville to ask military assistance from the Almoravids, who then occupied Seville. History The ''taifa'' (principality) began as a small, weakly-defended territory comprising parts of the modern Spanish provinces of Seville, Huelva, and Cádiz, but quickly emerged as the most powerful taifa of the time, after its rulers began a policy of expansion.
