Fátima De Madrid
Fátima de Madrid is the name given to an Arab Muslim astronomer and mathematician who supposedly lived during the late 10th and early 11th centuries in Al-Andalus, Islamic Spain. She was purportedly the daughter of the astronomer Maslama al-Majriti, with whom she is said to have worked on several astronomical and mathematical treatises, including the astronomical tables of Muhammad ibn Musa al-Khwarizmi. The earliest known account of her is the 1924 edition of the Enciclopedia universal ilustrada europeo-americana, Enciclopedia Espasa-Calpe, and historians have cast doubt on whether she actually existed. Purported career Fátima de Madrid is said to have lived in Córdoba, Spain, Córdoba, under the Caliphate of Córdoba, during the late 10th and early 11th centuries. She is said to have been the daughter of the famous Islamic astronomer and scientist Maslama al-Majriti. Her most famous supposed work, known as the "Corrections from Fátima," are a series of astronomical and mat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arab
The Arabs (singular: Arab; singular ar, عَرَبِيٌّ, DIN 31635: , , plural ar, عَرَب, 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 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, Turkey, Indonesia, and Iran. In modern usage, the term "Arab" tends to refer to those who both 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 (the remainder consisted mostly of Arab Christians), while Arab Muslims are only 20 percent of the ...

Almagest
The ''Almagest'' is a 2nd-century Greek-language mathematical and astronomical treatise on the apparent motions of the stars and planetary paths, written by Claudius Ptolemy ( ). One of the most influential scientific texts in history, it canonized a geocentric model of the Universe that was accepted for more than 1,200 years from its origin in Hellenistic Alexandria, in the medieval Byzantine and Islamic worlds, and in Western Europe through the Middle Ages and early Renaissance until Copernicus. It is also a key source of information about ancient Greek astronomy. Ptolemy set up a public inscription at Canopus, Egypt, in 147 or 148. N. T. Hamilton found that the version of Ptolemy's models set out in the ''Canopic Inscription'' was earlier than the version in the ''Almagest''. Hence the ''Almagest'' could not have been completed before about 150, a quarter-century after Ptolemy began observing. Names The name comes from Arabic ', with ' meaning "the", and ''magesti'' bei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
People Whose Existence Is Disputed
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of ...

Fictional Mathematicians
Fiction is any creative work, chiefly any narrative work, portraying individuals, events, or places that are imaginary, or in ways that are imaginary. Fictional portrayals are thus inconsistent with history, fact, or plausibility. In a traditional narrow sense, "fiction" refers to written narratives in prose often referring specifically to novels, novellas, and short stories. More broadly, however, fiction encompasses imaginary narratives expressed in any medium, including not just writings but also live theatrical performances, films, television programs, radio dramas, comics, role-playing games, and video games. Definition Typically, the fictionality of a work is publicly marketed and so the audience expects the work to deviate in some ways from the real world rather than presenting, for instance, only factually accurate portrayals or characters who are actual people. Because fiction is generally understood to not fully adhere to the real world, the themes and conte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astronomers From Al-Andalus
An astronomer is a scientist in the field of astronomy who focuses their studies on a specific question or field outside the scope of Earth. They observe astronomical objects such as stars, planets, moons, comets and galaxies – in either observational (by analyzing the data) or theoretical astronomy. Examples of topics or fields astronomers study include planetary science, solar astronomy, the origin or evolution of stars, or the formation of galaxies. A related but distinct subject is physical cosmology, which studies the Universe as a whole. Types Astronomers usually fall under either of two main types: observational and theoretical. Observational astronomers make direct observations of celestial objects and analyze the data. In contrast, theoretical astronomers create and investigate models of things that cannot be observed. Because it takes millions to billions of years for a system of stars or a galaxy to complete a life cycle, astronomers must observe snapshots of ...

Arab Women
The roles of women in the Arab world have changed throughout history, as the culture and society in which they live has undergone significant transformations. Historically, as well as presently, the situation of women differs greatly between Arabic speaking regions, their urban or rural population and age groups. Among other factors, these differences can be attributed to local traditions, culture and religion, women's social or legal status, their level of education, health or self-awareness. Since the 19th century, and notably through the influence of the colonization in North Africa, the Arab Renaissance in Egypt, Lebanon, and Syria, and the end of the Ottoman Empire, the social and economic changes in the Arab world have become greatly accelerated and diversified. History of women in the Arab world Arab women before Islam Many writers have discussed the status of women in pre-Islamic Arabia, and their findings have been mixed.Turner, Brian S. ''Islam'' ().

11th-century People From Al-Andalus
The 11th century is the period from 1001 ( MI) through 1100 ( MC) in accordance with the Julian calendar, and the 1st century of the 2nd millennium. In the history of Europe, this period is considered the early part of the High Middle Ages. There was, after a brief ascendancy, a sudden decline of Byzantine power and a rise of Norman domination over much of Europe, along with the prominent role in Europe of notably influential popes. Christendom experienced a formal schism in this century which had been developing over previous centuries between the Latin West and Byzantine East, causing a split in its two largest denominations to this day: Roman Catholicism and Eastern Orthodoxy. In Song dynasty China and the classical Islamic world, this century marked the high point for both classical Chinese civilization, science and technology, and classical Islamic science, philosophy, technology and literature. Rival political factions at the Song dynasty court created strife amongst t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
10th-century People From Al-Andalus
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 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Mathematics
The history of mathematics deals with the origin of discoveries in mathematics and the mathematical methods and notation of the past. Before the modern age and the worldwide spread of knowledge, written examples of new mathematical developments have come to light only in a few locales. From 3000 BC the Mesopotamian states of Sumer, Akkad and Assyria, followed closely by Ancient Egypt and the Levantine state of Ebla began using arithmetic, algebra and geometry for purposes of taxation, commerce, trade and also in the patterns in nature, the field of astronomy and to record time and formulate calendars. The earliest mathematical texts available are from Mesopotamia and Egypt – '' Plimpton 322'' ( Babylonian c. 2000 – 1900 BC), the ''Rhind Mathematical Papyrus'' ( Egyptian c. 1800 BC) and the '' Moscow Mathematical Papyrus'' (Egyptian c. 1890 BC). All of these texts mention the so-called Pythagorean triples, so, by inference, the Pythagorean theorem seems to be the most anci ...

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine. Dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
