He is best known for writing '' The Book of Knowledge of Ingenious Mechanical Devices'' ( ar, كتاب في معرفة الحيل الهندسية, lit=Book in knowledge of engineering tricks, translit=Kitab fi ma'rifat al-hiyal al-handasiya) in 1206, where he described 50 mechanical devices, along with instructions on how to construct them. He is credited with the invention of the elephant clock. He has been described as the "father of robotics" and modern day engineering.

Islamic Golden Age
The Islamic Golden Age was a period of cultural, economic, and scientific flourishing in the history of Islam, traditionally dated from the 8th century to the 14th century. This period is traditionally understood to have begun during the reign of the Abbasid caliph Harun al-Rashid (786 to 809) with the inauguration of the House of Wisdom in Baghdad, the world's largest city by then, where Muslim scholars and polymaths from various parts of the world with different cultural backgrounds were mandated to gather and translate all of the known world's classical knowledge into Aramaic and Arabic. The period is traditionally said to have ended with the collapse of the Abbasid caliphate due to Mongol invasions and the Siege of Baghdad in 1258. A few scholars date the end of the golden age around 1350 linking with the Timurid Renaissance, while several modern historians and scholars place the end of the Islamic Golden Age as late as the end of 15th to 16th centuries meeting with the I ...

Robotics
Robotics is an interdisciplinary branch of computer science and engineering. Robotics involves design, construction, operation, and use of robots. The goal of robotics is to design machines that can help and assist humans. Robotics integrates fields of mechanical engineering, electrical engineering, information engineering, mechatronics, electronics, bioengineering, computer engineering, control engineering, software engineering, mathematics, etc. Robotics develops machines that can substitute for humans and replicate human actions. Robots can be used in many situations for many purposes, but today many are used in dangerous environments (including inspection of radioactive materials, bomb detection and deactivation), manufacturing processes, or where humans cannot survive (e.g. in space, underwater, in high heat, and clean up and containment of hazardous materials and radiation). Robots can take any form, but some are made to resemble humans in appearance. This is claim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trial And Error
Trial and error is a fundamental method of problem-solving characterized by repeated, varied attempts which are continued until success, or until the practicer stops trying. According to W.H. Thorpe, the term was devised by C. Lloyd Morgan (1852–1936) after trying out similar phrases "trial and failure" and "trial and practice". Under Morgan's Canon, animal behaviour should be explained in the simplest possible way. Where behavior seems to imply higher mental processes, it might be explained by trial-and-error learning. An example is a skillful way in which his terrier Tony opened the garden gate, easily misunderstood as an insightful act by someone seeing the final behavior. Lloyd Morgan, however, had watched and recorded the series of approximations by which the dog had gradually learned the response, and could demonstrate that no insight was required to explain it. Edward Lee Thorndike was the initiator of the theory of trial and error learning based on the findings he sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arabs
The Arabs (singular: Arab; singular ar, عَرَبِيٌّ, DIN 31635: , , plural ar, عَرَب, DIN 31635, DIN 31635: , Arabic pronunciation: ), also known as the Arab people, are an ethnic group mainly inhabiting the Arab world in Western Asia, North Africa, the Horn of Africa, and the western List of islands in the Indian Ocean, Indian Ocean islands (including the Comoros). An Arab diaspora is also present around the world in significant numbers, most notably in the Americas, Western Europe, Arabs in Turkey, Turkey, Arab Indonesians, Indonesia, and Iranian Arabs, Iran. In modern usage, the term "Arab" tends to refer to those who both Arab identity, carry that ethnic identity and speak Arabic as their native language. This contrasts with the narrower traditional definition, which refers to the descendants of the tribes of Arabia. The religion of Islam was developed in Arabia, and Classical Arabic serves as the language of Islamic literature. 93 percent of Arabs are Muslims ...

Saladin
Yusuf ibn Ayyub ibn Shadi () ( – 4 March 1193), commonly known by the epithet Saladin,, ; ku, سهلاحهدین, ; was the founder of the Ayyubid dynasty.

Alongside his uncle Shirkuh, a military general of the Zengid dynasty, Saladin was sent to Egypt under the Fatimid Caliphate in 1164, on the orders of Nur ad-Din. With their original purpose being to help restore Shawar as the to the teenage Fatimid caliph al-Adid, a power struggle ensued between Shirkuh and Shawar after the latter was reinstated.

Zengid Dynasty
The Zengid dynasty was a Muslim dynasty of Oghuz Turkic origin, which ruled parts of the Levant and Upper Mesopotamia on behalf of the Seljuk Empire and eventually seized control of Egypt in 1169. In 1174 the Zengid state extended from Tripoli to Hamadan and from Yemen to Sivas. The dynasty was founded by Imad ad-Din Zengi. History Zengi, son of Aq Sunqur al-Hajib, became the Seljuk atabeg of Mosul in 1127. He quickly became the chief Turkic potentate in Northern Syria and Iraq, taking Aleppo from the squabbling Artuqids in 1128 and capturing the County of Edessa from the Crusaders after the siege of Edessa in 1144. This latter feat made Zengi a hero in the Muslim world, but he was assassinated by a slave two years later, in 1146. On Zengi's death, his territories were divided, with Mosul and his lands in Iraq going to his eldest son Saif ad-Din Ghazi I, and Aleppo and Edessa falling to his second son, Nur ad-Din, atabeg of Aleppo. Nur ad-Din proved to be as competent as his f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vassal State
A vassal state is any state that has a mutual obligation to a superior state or empire, in a status similar to that of a vassal in the feudal system in medieval Europe. Vassal states were common among the empires of the Near East, dating back to the era of the Egyptian, Hittite and Mitanni conflict, as well as ancient China. The use of vassal states continued through the Middle Ages, with the last empire to use such states being the Ottoman Empire. The relationships between vassal rulers and empires was dependent on the policies and agreements of each empire. While payment of tribute and military service is common amongst vassal states, the degree of independence and benefits given to vassal states varied. Today, more common terms are puppet state, protectorate, client state, associated state or satellite state.

Anatolia
Anatolia, tr, Anadolu Yarımadası), and the Anatolian plateau, also known as Asia Minor, is a large peninsula in Western Asia and the westernmost protrusion of the Asian continent. It constitutes the major part of modern-day Turkey. The region is bounded by the Turkish Straits to the northwest, the Black Sea to the north, the Armenian Highlands to the east, the Mediterranean Sea to the south, and the Aegean Sea to the west. The Sea of Marmara forms a connection between the Black and Aegean seas through the Bosporus and Dardanelles straits and separates Anatolia from Thrace on the Balkan peninsula of Southeast Europe. The eastern border of Anatolia has been held to be a line between the Gulf of Alexandretta and the Black Sea, bounded by the Armenian Highlands to the east and Mesopotamia to the southeast. By this definition Anatolia comprises approximately the western two-thirds of the Asian part of Turkey. Today, Anatolia is sometimes considered to be synonymous with Asian ...
