Muhammad Al-Baghdadi
Abu Bakr Muhammad Ibn ‘Abd al-Bāqī al-Baghdadi al-Ansārī al-Kaabī (1050-1141) (Arabic: محمد بن عبد الباقي البغدادي) also known as Qadi al-Maristan, was an Arab jurist and mathematician. He was the author of a commentary on the tenth book of Euclid's Elements, which was translated by Gerard of Cremona as ''Liber judei super decimum Euclidis''. The work was popular in Europe with several Latin manuscripts still extant. Other works include: * ''Jadawil al-Jayb al-Mahlul al-Daqiqa'' (detailed tables of sines for each minute), * ''Risala fi Taqrib Usul al-Hisab fi' al-Jabr wa-‘l-Muqabala'' (Treatise on approximation of principles of arithmetic) * ''Kitab al-Tabaqat fi Sharh al-Misaha'' (book on measurements) Machometus Bagdedinus Muhammad Ibn ‘Abd al-Bāqī has been identified by modern scholars with the Latin name, Machometus Bagdedinus, although this identification is sometimes disputed. Machometus Bagdedinus, was an Arab author whose translated wor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muhammad - De Superficierum Divisionibus, 1570 - 1320699
Muhammad ( ar, مُحَمَّد; 570 – 8 June 632 CE) was an Arab religious, social, and political leader and the founder of Islam. According to Islamic doctrine, he was a prophet divinely inspired to preach and confirm the monotheistic teachings of Adam, Abraham, Moses, Jesus, and other prophets. He is believed to be the Seal of the Prophets within Islam. Muhammad united Arabia into a single Muslim polity, with the Quran as well as his teachings and practices forming the basis of Islamic religious belief. Muhammad was born approximately 570CE in Mecca. He was the son of Abdullah ibn Abd al-Muttalib and Amina bint Wahb. His father Abdullah was the son of Quraysh tribal leader Abd al-Muttalib ibn Hashim, and he died a few months before Muhammad's birth. His mother Amina died when he was six, leaving Muhammad an orphan. He was raised under the care of his grandfather, Abd al-Muttalib, and paternal uncle, Abu Talib.

Ansar (Islam)
The ''Ansar'' ( ar, الأنصار, al-Anṣār, The Helpers’ or ‘Those who bring victory) were the local inhabitants of Medina who, in Islamic tradition, took the Islamic prophet Muhammad and his followers (the '' Muhajirun'') into their homes when they emigrated from Mecca during the '' hijra''. They belonged to the tribes of Banu Khazraj and Banu Aus. Background The Medinese, which consisted of Aws and Khazraj, along with their Jewish allies, Banu Nadir, Banu Qurayza, and Banu Qaynuqa, were involved in degenerating years of warfare such as battle of Sumair, battle of Banu Jahjaha of Aus-Banu Mazin of Khazraj, battle of Sararah day, battle of Banu Wa'il ibn Zayd, battle of Zhufr-Malik, battle of Fari', battle of Hathib, battle of Rabi' day, first battle of Fijar in Yathrib (not Fijar war between Qays with Kinana in Mecca), battle of Ma'is, battle of Mudharras, and second battle of Fijar in Yathrib.

Arabic
Arabic (, ' ; , ' or ) is a Semitic language spoken primarily across the Arab world.Semitic languages: an international handbook / edited by Stefan Weninger; in collaboration with Geoffrey Khan, Michael P. Streck, Janet C. E.Watson; Walter de Gruyter GmbH & Co. KG, Berlin/Boston, 2011. Having emerged in the 1st century, it is named after the Arab people; the term "Arab" was initially used to describe those living in the Arabian Peninsula, as perceived by geographers from ancient Greece. Since the 7th century, Arabic has been characterized by diglossia, with an opposition between a standard prestige language—i.e., Literary Arabic: Modern Standard Arabic (MSA) or Classical Arabic—and diverse vernacular varieties, which serve as mother tongues. Colloquial dialects vary significantly from MSA, impeding mutual intelligibility. MSA is only acquired through formal education and is not spoken natively. It is the language of literature, official documents, and formal writ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arab
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 ...

Jurist
A jurist is a person with expert knowledge of law; someone who analyses and comments on law. This person is usually a specialist legal scholar, mostly (but not always) with a formal qualification in law and often a legal practitioner. In the United Kingdom the term "jurist" is mostly used for legal academics, while in the United States the term may also be applied to a judge. With reference to Roman law, a "jurist" (in English) is a jurisconsult (''iurisconsultus''). The English term ''jurist'' is to be distinguished from similar terms in other European languages, where it may be synonymous with legal professional, meaning anyone with a professional law degree that qualifies for admission to the legal profession, including such positions as judge or attorney. In Germany, Scandinavia Scandinavia; Sámi languages: /. ( ) is a subregion in Northern Europe, with strong historical, cultural, and linguistic ties between its constituent peoples.

Mathematician
A mathematician is someone who uses an extensive knowledge of mathematics in their work, typically to solve mathematical problems. Mathematicians are concerned with numbers, data, quantity, mathematical structure, structure, space, Mathematical model, models, and mathematics#Calculus and analysis, change. History One of the earliest known mathematicians were Thales of Miletus (c. 624–c.546 BC); he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed. He is credited with the first use of deductive reasoning applied to geometry, by deriving four corollaries to Thales' Theorem. The number of known mathematicians grew when Pythagoras of Samos (c. 582–c. 507 BC) established the Pythagoreans, Pythagorean School, whose doctrine it was that mathematics ruled the universe and whose motto was "All is number". It was the Pythagoreans who coined the term "mathematics", and with whom the study of mathemat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Euclid
Euclid (; grc-gre, Εὐκλείδης; BC) was an ancient Greek mathematician active as a geometer and logician. Considered the "father of geometry", he is chiefly known for the ''Elements'' treatise, which established the foundations of geometry that largely dominated the field until the early 19th century. His system, now referred to as Euclidean geometry, involved new innovations in combination with a synthesis of theories from earlier Greek mathematicians, including Eudoxus of Cnidus, Hippocrates of Chios, Thales and Theaetetus. With Archimedes and Apollonius of Perga, Euclid is generally considered among the greatest mathematicians of antiquity, and one of the most influential in the history of mathematics. Very little is known of Euclid's life, and most information comes from the philosophers Proclus and Pappus of Alexandria many centuries later. Until the early Renaissance he was often mistaken for the earlier philosopher Euclid of Megara, causing his biograph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gerard Of Cremona
Gerard of Cremona (Latin: ''Gerardus Cremonensis''; c. 1114 – 1187) was an Italian translator of scientific books from Arabic into Latin. He worked in Toledo, Kingdom of Castile and obtained the Arabic books in the libraries at Toledo. Some of the books had been originally written in Greek and, although well known in Byzantine Constantinople and Greece at the time, were unavailable in Greek or Latin in Western Europe. Gerard of Cremona is the most important translator among the Toledo School of Translators who invigorated Western medieval Europe in the twelfth century by transmitting the Arabs' and ancient Greeks' knowledge in astronomy, medicine and other sciences, by making the knowledge available in Latin. One of Gerard's most famous translations is of Ptolemy's ''Almagest'' from Arabic texts found in Toledo. Confusingly there appear to have been two translators of Arabic text into Latin known as ''Gerard of Cremona'', the one active in the 12th century who concentrated on ...

John Dee
John Dee (13 July 1527 – 1608 or 1609) was an English mathematician, astronomer, astrologer, teacher, occultist, and alchemist. He was the court astronomer for, and advisor to, Elizabeth I, and spent much of his time on alchemy, divination, and Hermetic philosophy. As an antiquarian, he had one of the largest libraries in England at the time. As a political advisor, he advocated the foundation of English colonies in the New World to form a " British Empire", a term he is credited with coining. Dee eventually left Elizabeth's service and went on a quest for additional knowledge in the deeper realms of the occult and supernatural. He aligned himself with several individuals who may have been charlatans, travelled through Europe and was accused of spying for the English crown. Upon his return to England, he found his home and library vandalised. He eventually returned to the Queen's service, but was turned away when she was succeeded by James I. He died in poverty in Lon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Federico Commandino
Federico Commandino (1509 – 5 September 1575) was an Italian humanist and mathematician. Born in Urbino, he studied at Padua and at Ferrara, where he received his doctorate in medicine. He was most famous for his central role as translator of works of ancient mathematicians. In this, his sources were primarily written in Greek and secondarily in Arabic, while his translations were primarily in Latin and secondarily in Italian. He was responsible for the publication of many treatises of Archimedes. He also translated the works of Aristarchus of Samos (''On the sizes and distances of the Sun and the Moon''), Pappus of Alexandria (''Mathematical collection''), Hero of Alexandria (''Pneumatics''), Ptolemy of Alexandria (''Planisphere'' and ''Analemma''), Apollonius of Perga (''Conics'') and Euclid of Alexandria (''Elements''). Among his pupils was Guidobaldo del Monte and Bernardino Baldi. Commandino maintained a correspondence with the astronomer Francesco Maurolico. The propo ...

1050 Births
1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit (measurement), unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest Positive number, positive integer. It is also sometimes considered the first of the sequence (mathematics), infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally ac ...
