Arab Agricultural RevolutionThe Arab Agricultural Revolution was the transformation in agriculture in the Old World during the Islamic Golden Age (8th to 13th centuries). The agronomic literature of the time, with major books by Ibn Bassal and Abū l-Khayr al-Ishbīlī, demonstrates the extensive diffusion of useful plants to Medieval Spain (al-Andalus), and the growth in Islamic scientific knowledge of agriculture and horticulture. Medieval Arab historians and geographers described al-Andalus as a fertile and prosperous region with abundant water, full of fruit from trees such as the olive and pomegranate.
HospitalA hospital is a healthcare institution providing patient treatment with specialized health science and auxiliary healthcare staff and medical equipment. The best-known type of hospital is the general hospital, which typically has an emergency department to treat urgent health problems ranging from fire and accident victims to a sudden illness. A district hospital typically is the major health care facility in its region, with many beds for intensive care and additional beds for patients who need long-term care.
MadrasaMadrasa (məˈdræsə, also US-rɑːs-, UKˈmædrɑːsə; Arabic: مدرسة mædˈræ.sæ, ˈmad.ra.sa, pl. مدارس, ALA) is the Arabic word for any type of educational institution, secular or religious (of any religion), whether for elementary education or higher learning. The word is variously transliterated Madrasah arifah, medresa, madrassa, madraza, medrese, etc. In countries outside the Arab world, the word usually refers to a specific type of religious school or college for the study of the religion of Islam, though this may not be the only subject studied.
Alchemy in the medieval Islamic worldAlchemy in the medieval Islamic world refers to both traditional alchemy and early practical chemistry (the early chemical investigation of nature in general) by Muslim scholars in the medieval Islamic world. The word alchemy was derived from the Arabic word كيمياء or kīmiyāʾ and may ultimately derive from the ancient Egyptian word kemi, meaning black. After the fall of the Western Roman Empire and the Islamic conquest of Roman Egypt, the focus of alchemical development moved to the Caliphate and the Islamic civilization.
History of scientific methodThe history of scientific method considers changes in the methodology of scientific inquiry, as distinct from the history of science itself. The development of rules for scientific reasoning has not been straightforward; scientific method has been the subject of intense and recurring debate throughout the history of science, and eminent natural philosophers and scientists have argued for the primacy of one or another approach to establishing scientific knowledge.
Latin translations of the 12th centuryLatin translations of the 12th century were spurred by a major search by European scholars for new learning unavailable in western Europe at the time; their search led them to areas of southern Europe, particularly in central Spain and Sicily, which recently had come under Christian rule following their reconquest in the late 11th century. These areas had been under Muslim rule for a considerable time, and still had substantial Arabic-speaking populations to support their search.
Logic in Islamic philosophyEarly Islamic law placed importance on formulating standards of argument, which gave rise to a "novel approach to logic" (منطق manṭiq "speech, eloquence") in Kalam (Islamic scholasticism). However, with the rise of the Mu'tazili philosophers, who highly valued Aristotle's Organon, this approach was displaced by the older ideas from Hellenistic philosophy. The works of al-Farabi, Avicenna, al-Ghazali and other Muslim logicians who often criticized and corrected Aristotelian logic and introduced their own forms of logic, also played a central role in the subsequent development of European logic during the Renaissance.
Islamic geometric patternsIslamic geometric patterns are one of the major forms of Islamic ornament, which tends to avoid using figurative images, as it is forbidden to create a representation of an important Islamic figure according to many holy scriptures. The geometric designs in Islamic art are often built on combinations of repeated squares and circles, which may be overlapped and interlaced, as can arabesques (with which they are often combined), to form intricate and complex patterns, including a wide variety of tessellations.
MuqarnasMuqarnas (مقرنص; مقرنس, or آهوپای), also known in Iberian architecture as Mocárabe, is a form of ornamented vaulting in Islamic architecture. It is the archetypal form of Islamic architecture, integral to the vernacular of Islamic buildings. It was most likely first developed in eleventh-century Iraq, though the earliest preserved examples are also found outside this region. The muqarnas structure originated from the squinch.
Ancient Greek medicineAncient Greek medicine was a compilation of theories and practices that were constantly expanding through new ideologies and trials. The Greek term for medicine was iatrikē (Greek: ἰατρική). Many components were considered in ancient Greek medicine, intertwining the spiritual with the physical. Specifically, the ancient Greeks believed health was affected by the humors, geographic location, social class, diet, trauma, beliefs, and mindset. Early on the ancient Greeks believed that illnesses were "divine punishments" and that healing was a "gift from the Gods".
AvicennaIbn Sina (ابن سینا; 980 – June 1037 CE), commonly known in the West as Avicenna (ˌævɪˈsɛnə,_ˌɑːvɪ-), was the preeminent philosopher and physician of the Muslim world, flourishing during the Islamic Golden Age, serving in the courts of various Iranian rulers. He is often described as the father of early modern medicine. His philosophy was of the Muslim Peripatetic school derived from Aristotelianism.
Seljuk EmpireThe Seljuk Empire, or the Great Seljuk Empire, was a high medieval, culturally Turco-Persian empire, founded and ruled by the Qïnïq branch of Oghuz Turks. It spanned a total area of from Anatolia and the Levant in the west to the Hindu Kush in the east, and from Central Asia in the north to the Persian Gulf in the south. The Seljuk Empire was founded in 1037 by Tughril (990–1063) and his brother Chaghri (989–1060), both of whom co-ruled over its territories; there are indications that the Seljuk leadership otherwise functioned as a triumvirate and thus included Musa Yabghu, the uncle of the aforementioned two.
Emission theory (vision)Emission theory or extramission theory (variants: extromission) or extromissionism is the proposal that visual perception is accomplished by eye beams emitted by the eyes. This theory has been replaced by intromission theory (or intromissionism), which is that visual perception comes from something representative of the object (later established to be rays of light reflected from it) entering the eyes. Modern physics has confirmed that light is physically transmitted by photons from a light source, such as the sun, to visible objects, and finishing with the detector, such as a human eye or camera.
