Joseph Of Spain
Joseph of Spain was a Jewish merchant of the ninth and tenth centuries CE and may have been a Radhanite. It is unknown if he was the "Joseph of Spain" who authored numerous mathematical treatises in use in Europe in medieval times. Abraham ibn Daud and other sources credit Joseph with bringing the so-called "Arabic numerals Arabic numerals are the ten numerical digits: , , , , , , , , and . They are the most commonly used symbols to write decimal numbers. They are also used for writing numbers in other systems such as octal, and for writing identifiers such as ..." from India to Europe.

Merchant
A merchant is a person who trades in commodities produced by other people, especially one who trades with foreign countries. Historically, a merchant is anyone who is involved in business or trade. Merchants have operated for as long as industry, commerce, and trade have existed. In 16th-century Europe, two different terms for merchants emerged: referred to local traders (such as bakers and grocers) and ( nl, koopman) referred to merchants who operated on a global stage, importing and exporting goods over vast distances and offering added-value services such as credit and finance. The status of the merchant has varied during different periods of history and among different societies. In modern times, the term ''merchant'' has occasionally been used to refer to a businessperson or someone undertaking activities (commercial or industrial) for the purpose of generating profit, cash flow, sales, and revenue using a combination of human, financial, intellectual and physical capit ...

Radhanite
The Radhanites or Radanites (; ar, الرذنية, ''ar-Raðaniyya'') were early medieval Jewish merchants, active in the trade between Christendom and the Muslim world during roughly the 8th to 10th centuries. Many trade routes previously established under the Roman Empire continued to function during that period—largely through their efforts. Their trade network covered much of Europe, North Africa, the Middle East, Central Asia, and parts of India and China. Only a limited number of primary sources use the term, and it remains unclear whether they referred to a specific guild, or to a clan, or generically to Jewish merchants in the trans-Eurasian trade network. Name Several etymologies have been suggested for the word "Radhanite". Many scholars, including Barbier de Meynard and Moshe Gil, believe it refers to a district in Mesopotamia called " the land of Radhan" in Arabic and Hebrew texts of the period. Another hypothesis suggests that the name might be derived from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abraham Ibn Daud
Abraham ibn Daud ( he, אַבְרָהָם בֵּן דָּוִד הַלֵּוִי אִבְּן דָּאוּד; ar, ابراهيم بن داود) was a Spanish-Jewish astronomer, historian, and philosopher; born at Córdoba, Spain about 1110; died in Toledo, Spain, according to common report, a martyr about 1180. He is sometimes known by the abbreviation Rabad I or Ravad I. His mother belonged to a family famed for its learning. Some scholars believe he is the Arabic-into-Latin translator known as “Avendauth.” Works His chronicle, a work written in Hebrew in 1161 under the title of '' Sefer ha-Qabbalah'' (; some manuscripts give the title as ''Seder ha-Qabbalah'', i.e. the "Order of Tradition"), in which he fiercely attacked the contentions of Karaism and justified Rabbinic Judaism by the establishment of a chain of traditions from Moses to his own time, is replete with valuable general information, especially relating to the time of the Geonim and to the history of th ...

Arabic Numerals
Arabic numerals are the ten numerical digits: , , , , , , , , and . They are the most commonly used symbols to write decimal numbers. They are also used for writing numbers in other systems such as octal, and for writing identifiers such as computer symbols, trademarks, or license plates. The term often implies a decimal number, in particular when contrasted with Roman numerals. They are also called Western Arabic numerals, Ghubār numerals, Hindu-Arabic numerals, Western digits, Latin digits, or European digits. The ''Oxford English Dictionary'' differentiates them with the fully capitalized ''Arabic Numerals'' to refer to the Eastern digits. The term numbers or numerals or digits often implies only these symbols, however this can only be inferred from context. It was in the Algerian city of Béjaïa that the Italian scholar Fibonacci first encountered the numerals; his work was crucial in making them known throughout Europe.

Explorers Of Asia
Exploration refers to the historical practice of discovering remote lands. It is studied by geographers and historians. Two major eras of exploration occurred in human history: one of convergence, and one of divergence. The first, covering most of ''Homo sapiens'' history, saw humans moving out of Africa, settling in new lands, and developing distinct cultures in relative isolation. Early explorers settled in Europe and Asia; 14,000 years ago, some crossed the Ice Age land bridge from Siberia to Alaska, and moved southbound to settle in the Americas. For the most part, these cultures were ignorant of each other's existence. The second period of exploration, occurring over the last 10,000 years, saw increased cross-cultural exchange through trade and exploration, and marked a new era of cultural intermingling, and more recently, convergence. Early writings about exploration date back to the 4th millennium B.C. in ancient Egypt. One of the earliest and most impactful thinkers of ...

9th-century Mathematicians
The 9th century was a period from 801 ( DCCCI) through 900 ( CM) in accordance with the Julian calendar. The Carolingian Renaissance and the Viking raids occurred within this period. In the Middle East, the House of Wisdom was founded in Abbasid Baghdad, attracting many scholars to the city. The field of algebra was founded by the Muslim polymath al-Khwarizmi. The most famous Islamic Scholar Ahmad ibn Hanbal was tortured and imprisoned by Abbasid official Ahmad ibn Abi Du'ad during the reign of Abbasid caliph al-Mu'tasim and caliph al-Wathiq. In Southeast Asia, the height of the Mataram Kingdom happened in this century, while Burma would see the establishment of the major kingdom of Pagan. Tang China started the century with the effective rule under Emperor Xianzong and ended the century with the Huang Chao rebellions. While the Maya experienced widespread political collapse in the central Maya region, resulting in internecine warfare, the abandonment of cities ...

10th-century Mathematicians
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 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 integer. It is also sometimes considered the first of the 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 accepted until the mid-20th century. Additionally, 1 is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
