Muhammad Ibn Nasr Ibn Al-Qaysarani
Abū ʿAbdallāh Muḥammad ibn Naṣr (1085–1154), known as al-Qaysarānī or Ibn al-Qaysarānī, was a Syrian Muslim poet who wrote in Arabic under the Zangid dynasty. He had a broad and scientific education, which included a sojourn in Iraq. He was one of the most renowned poets of his age, and the most prolific Zangid propagandist. He wrote extensively against the Crusades for his masters. Life Ibn al-Qaysarānī was born in AD 1085 ( AH 478) in Acre in Palestine, then part of the Seljuk Empire. He sometimes bears the tribal ''nisba'' al-Makhzūmī, which would make him a relative of Khālid ibn al-Walīd al-Makhzūmī, one of the earliest Muslim commanders, but medieval chroniclers generally reject this relationship. When the Fatimid Caliphate began advancing into Palestine, his father, Naṣr ibn Ṣaghīr, moved the family to Caesarea Maritima. There, according to the chronicles, he was educated in Islamic tradition and the Arabic language. The evidence of his poetry ...

Kunya (Arabic)
A ''kunya'' ( ar, كُنية) is a teknonym in Arabic names, the name of an adult usually derived from their oldest child. A kunya is a component of an Arabic name, a type of epithet, in theory referring to the bearer's first-born son or daughter. By extension, it may also have hypothetical or metaphorical references, e.g. in a ''nom de guerre'' or a nickname, without literally referring to a son or a daughter. Use of a kunya implies a familiar but respectful setting. A kunya is expressed by the use of '' abū'' (father) or '' umm'' (mother) in a genitive construction, i.e. "father of" or "mother of" as an honorific in place of or alongside given names in the Arab world and the Islamic world more generally. General use '' Abū'' or '' Umm'' precedes the son's or daughter's name, in a genitive construction (''ʼiḍāfa''). For example, the English equivalent would be to call a man "Father of John" if his eldest son is named John. Use of the ''kunya'' normally signifies some close ...

Baldwin I Of Jerusalem
Baldwin I, also known as Baldwin of Boulogne (1060s – 2April 1118), was the first count of Edessa from 1098 to 1100, and king of Jerusalem from 1100 to his death in 1118. He was the youngest son of Eustace II, Count of Boulogne, and Ida of Lorraine and married a Norman noblewoman, Godehilde of Tosny. He received the County of Verdun in 1096, but he soon joined the crusader army of his brother Godfrey of Bouillon and became one of the most successful commanders of the First Crusade. While the main crusader army was marching across Asia Minor in 1097, Baldwin and the Norman Tancred launched a separate expedition against Cilicia. Tancred tried to capture Tarsus in September, but Baldwin forced him to leave it, which gave rise to an enduring conflict between them. Baldwin seized important fortresses in the lands to the west of the Euphrates with the assistance of local Armenians. Thoros of Edessa invited him to come to Edessa to fight against the Seljuks.

Horology
Horology (; related to Latin '; ; , interfix ''-o-'', and suffix ''-logy''), . is the study of the measurement of time. Clocks, watches, clockwork, sundials, hourglasses, clepsydras, timers, time recorders, marine chronometers, and atomic clocks are all examples of instruments used to measure time. In current usage, horology refers mainly to the study of mechanical time-keeping devices, while chronometry more broadly includes electronic devices that have largely supplanted mechanical clocks for the best accuracy and precision in time-keeping. People interested in horology are called ''horologists''. That term is used both by people who deal professionally with timekeeping apparatuses (watchmakers, clockmakers), as well as aficionados and scholars of horology. Horology and horologists have numerous organizations, both professional associations and more scholarly societies. The largest horological membership organisation globally is the NAWCC, the National Association of Watc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geometry
Geometry (; ) is, with arithmetic, one of the oldest branches of mathematics. It is concerned with properties of space such as the distance, shape, size, and relative position of figures. A mathematician who works in the field of geometry is called a ''geometer''. Until the 19th century, geometry was almost exclusively devoted to Euclidean geometry, which includes the notions of point, line, plane, distance, angle, surface, and curve, as fundamental concepts. During the 19th century several discoveries enlarged dramatically the scope of geometry. One of the oldest such discoveries is Carl Friedrich Gauss' ("remarkable theorem") that asserts roughly that the Gaussian curvature of a surface is independent from any specific embedding in a Euclidean space. This implies that surfaces can be studied ''intrinsically'', that is, as stand-alone spaces, and has been expanded into the theory of manifolds and Riemannian geometry. Later in the 19th century, it appeared that geome ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astronomy
Astronomy () is a natural science that studies celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, 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 Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole. Astronomy is one of the oldest natural sciences. The early civilizations in recorded history made methodical observations of the night sky. These include the Babylonians, Greeks, Indians, Egyptians, Chinese, Maya, and many ancient indigenous peoples of the Americas. In the past, astronomy included disciplines as diverse as astrometry, celestial navigation, observational astronomy, and the making of calendars. ...

Astrology
Astrology is a range of divinatory practices, recognized as pseudoscientific since the 18th century, that claim to discern information about human affairs and terrestrial events by studying the apparent positions of celestial objects. Different cultures have employed forms of astrology since at least the 2nd millennium BCE, these practices having originated in calendrical systems used to predict seasonal shifts and to interpret celestial cycles as signs of divine communications. Most, if not all, cultures have attached importance to what they observed in the sky, and some—such as the Hindus, Chinese, and the Maya—developed elaborate systems for predicting terrestrial events from celestial observations. Western astrology, one of the oldest astrological systems still in use, can trace its roots to 19th–17th century BCE Mesopotamia, from where it spread to Ancient Greece, Rome, the Islamic world, and eventually Central and Western Europe. Contemporary Western astr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arithmetic
Arithmetic () is an elementary part of mathematics that consists of the study of the properties of the traditional operations on numbers— addition, subtraction, multiplication, division, exponentiation, and extraction of roots. In the 19th century, Italian mathematician Giuseppe Peano formalized arithmetic with his Peano axioms, which are highly important to the field of mathematical logic today. History The prehistory of arithmetic is limited to a small number of artifacts, which may indicate the conception of addition and subtraction, the best-known being the Ishango bone from central Africa, dating from somewhere between 20,000 and 18,000 BC, although its interpretation is disputed. The earliest written records indicate the Egyptians and Babylonians used all the elementary arithmetic operations: addition, subtraction, multiplication, and division, as early as 2000 BC. These artifacts do not always reveal the specific process used for solving problems, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sunnah
In Islam, , also spelled ( ar, سنة), are the traditions and practices of the Islamic prophet Muhammad that constitute a model for Muslims to follow. The sunnah is what all the Muslims of Muhammad's time evidently saw and followed and passed on to the next generations. According to classical Islamic theories, the sunnah are documented by hadith (the verbally transmitted record of the teachings, deeds and sayings, silent permissions or disapprovals of Muhammad), and along with the Quran (the book of Islam), are the divine revelation ('' Wahy'') delivered through Muhammad Brown, ''Rethinking tradition in modern Islamic thought'', 1996: p.7 that make up the primary sources of Islamic law and belief/theology. Differing from Sunni classical Islamic theories are those of Shia Muslims, who hold that the Twelve Imams interpret the sunnah, and Sufi who hold that Muhammad transmitted the values of sunnah "through a series of Sufi teachers." According to Muslim belief, Muhammad was t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caesarea Maritima
Caesarea Maritima (; Greek: ''Parálios Kaisáreia''), formerly Strato's Tower, also known as Caesarea Palestinae, was an ancient city in the Sharon plain on the coast of the Mediterranean, now in ruins and included in an Israeli national park. For centuries it was a major intellectual hub of the Mediterranean and cultural capital of Palestine. The city and harbour were built under Herod the Great during c. 22–10 or 9 BCE near the site of a former Phoenician naval station known as ''Stratonos pyrgos'' (Στράτωνος πύργος, "Straton's Tower"), probably named after the 4th century BCE king of Sidon, Strato I. It later became the provincial capital of Roman Judea, Roman Syria Palaestina and Byzantine Palaestina Prima provinces. The city was populated throughout the 1st to 6th centuries AD and became an important early center of Christianity, early centre of Christianity during the Byzantine period. Its importance may have waned starting during the Muslim conques ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fatimid Caliphate
The Fatimid Caliphate was an Ismaili Shi'a caliphate extant from the tenth to the twelfth centuries AD. Spanning a large area of North Africa, it ranged from the Atlantic Ocean in the west to the Red Sea in the east. The Fatimids, a dynasty of Arab origin, trace their ancestry to Muhammad's daughter Fatima and her husband ‘Ali b. Abi Talib, the first Shi‘a imam. The Fatimids were acknowledged as the rightful imams by different Isma‘ili communities, but also in many other Muslim lands, including Persia and the adjacent regions. Originating during the Abbasid Caliphate, the Fatimids conquered Tunisia and established the city of " al-Mahdiyya" ( ar, المهدية). The Ismaili dynasty ruled territories across the Mediterranean coast of Africa and ultimately made Egypt the center of the caliphate. At its height, the caliphate included – in addition to Egypt – varying areas of the Maghreb, Sudan, Sicily, the Levant, and the Hijaz. Between 902 to 909 the foun ...
