Jabir Ibn Hayyan
Abū Mūsā Jābir ibn Ḥayyān (Arabic: , variously called al-Ṣūfī, al-Azdī, al-Kūfī, or al-Ṭūsī), died 806−816, is the purported author of a large number of works in Arabic, often called the Jabirian corpus. The treatises that survive today mainly deal with alchemy and chemistry, magic, and Shi'ite religious philosophy. However, the original scope of the corpus was vast, covering a wide range of topics ranging from cosmology, astronomy and astrology, over medicine, pharmacology, zoology and botany, to metaphysics, logic, and grammar. The works attributed to Jabir, which are tentatively dated to , contain the oldest known systematic classification of chemical substances, and the oldest known instructions for deriving an inorganic compound ( sal ammoniac or ammonium chloride) from organic substances (such as plants, blood, and hair) by chemical means. His works also contain one of the earliest known versions of the sulfur-mercury theory of metals, a mineralo ...

Islamic Golden Age
The Islamic Golden Age was a period of scientific, economic, and cultural flourishing in the history of Islam, traditionally dated from the 8th century to the 13th century. This period is traditionally understood to have begun during the reign of the Abbasid Caliphate, Abbasid caliph Harun al-Rashid (786 to 809) with the inauguration of the House of Wisdom, which saw Ulama, scholars from all over the Muslim world flock to Baghdad, the world's largest city at the time, to translate the known world's classical knowledge into Arabic and Persian language, Persian. The period is traditionally said to have ended with the collapse of the Abbasid caliphate due to Mongol invasions and conquests, Mongol invasions and the Siege of Baghdad (1258), Siege of Baghdad in 1258. There are a few alternative timelines. Some scholars extend the end date of the golden age to around 1350, including the Timurid Renaissance within it, while others place the end of the Islamic Golden Age as late as the en ...

History Of Zoology Through 1859
The history of zoology before Charles Darwin's 1859 theory of evolution traces the organized study of the animal kingdom from ancient to modern times. Although the concept of ''zoology'' as a single coherent field arose much later, systematic study of zoology is seen in the works of Aristotle and Galen in the ancient Greco-Roman world. This work was developed in the Middle Ages by Islamic medicine and scholarship, and their work was in turn extended by European scholars such as Albertus Magnus. During the European Renaissance and early modern period, zoological thought was revolutionized in Europe by a renewed interest in empiricism and the discovery of many novel organisms. Prominent in this movement were the anatomist Vesalius and the physiologist William Harvey, who used experimentation and careful observation, and naturalists such as Carl Linnaeus and Buffon who began to classify the diversity of life and the fossil record, as well as the development and behavior of organis ...

Pseudo-Geber
Pseudo-Geber (or "Middle Latin, Latin pseudo-Geber") is the presumed author or group of authors responsible for a corpus of pseudepigraphic alchemical writings dating to the late 13th and early 14th centuries. These writings were falsely attributed to Jabir ibn Hayyan (died 816, Latinisation of names, Latinized as Geber), an early Alchemy, alchemist of the Islamic Golden Age. The most important work of the Latin pseudo-Geber corpus is the ("The Height of the Perfection of Mastery"), which was likely written slightly before 1310. Its actual author has been tentatively identified as Paul of Taranto. The work was influential in the domain of alchemy and metallurgy in late medieval Europe. The work contains experimental demonstrations of the corpuscularianism, corpuscular nature of matter that were still being used by seventeenth-century chemists such as Daniel Sennert, who in turn influenced Robert Boyle. The work is among the first to describe nitric acid, aqua regia, and aqua fo ...

Latinisation Of Names
Latinisation (or Latinization) of names, also known as onomastic Latinisation (or onomastic Latinization), is the practice of rendering a ''non''-Latin name in a Neo-Latin, modern Latin style. It is commonly found with historical proper names, including personal names and toponyms, and in the standard binomial nomenclature of the life sciences. It goes further than romanisation, which is the transliteration of a word to the Latin alphabet from another script (e.g. Cyrillic). For authors writing in Latin, this change allows the name to function grammatically in a sentence through declension. In a scientific context, the main purpose of Latinisation may be to produce a name which is internationally consistent. Latinisation may be carried out by: * transforming the name into Latin sounds (e.g. for ), or * adding Latinate suffixes to the end of a name (e.g. for ''Heinrich Meibom (doctor), Meibom),'' or * translating a name with a specific meaning into Latin (e.g. for Italian ; b ...

Pseudonym
A pseudonym (; ) or alias () is a fictitious name that a person assumes for a particular purpose, which differs from their original or true meaning ( orthonym). This also differs from a new name that entirely or legally replaces an individual's own. Many pseudonym holders use them because they wish to remain anonymous and maintain privacy, though this may be difficult to achieve as a result of legal issues. Scope Pseudonyms include stage names, user names, ring names, pen names, aliases, superhero or villain identities and code names, gamertags, and regnal names of emperors, popes, and other monarchs. In some cases, it may also include nicknames. Historically, they have sometimes taken the form of anagrams, Graecisms, and Latinisations. Pseudonyms should not be confused with new names that replace old ones and become the individual's full-time name. Pseudonyms are "part-time" names, used only in certain contexts: to provide a more clear-cut separation between one's privat ...

Ja'far Al-Sadiq
Ja'far al-Sadiq (; –765) was a Muslim hadith transmitter and the last agreed-upon Shia Imam between the Twelvers and Isma'ilis. Known by the title al-Sadiq ("The Truthful"), Ja'far was the eponymous founder of the Ja'fari school of Islamic jurisprudence. In the canonical Twelver hadith collections, more traditions are cited from Ja'far than that of the other Imams combined, although their attribution to him is questionable, making it hard to determine his actual teachings.. Among the theological contributions ascribed to him are the doctrine of '' '' (divinely inspired designation of each Imam by the previous Imam) and '' '' (the infallibility of the Imams), as well as that of (religious dissimulation under persecution). Al-Sadiq is also revered by Sunni Muslims as a reliable transmitter of hadith, and a teacher to the Sunni scholars Abu Hanifa and Malik ibn Anas, the namesakes of the Hanafi and Maliki schools of jurisprudence. Al-Sadiq also figures prominently i ...

Imamate In Shia Doctrine
In Shia Islam, the Imamah () is a doctrine which asserts that certain individuals from the lineage of the Prophets in Islam, Islamic prophet Muhammad are to be accepted as leaders and guides of the ummah after the Succession to Muhammad, death of Muhammad. Imamah further says that Imams possess divine knowledge and authority (Ismah) as well as being part of the Ahl al-Bayt, the family of Muhammad. These Imams have the role of providing commentary and interpretation of the Quran as well as guidance. Etymology The word "Imām" denotes a person who stands or walks "in front". For Sunni Islam, the word is commonly used to mean a person who leads the course of prayer in the mosque. It also means the head of a ''madhhab'' ("school of thought"). However, from the Shia point of view this is merely the ''basic'' understanding of the word in the Arabic language and, for its proper religious usage, the word "Imam" is applicable ''only'' to those members of the house of Muhammad designate ...

History Of Mineralogy
Early writing on mineralogy, especially on gemstones, comes from ancient Babylonia, the ancient Greco-Roman world, ancient and medieval China, and Sanskrit texts from ancient India.Needham, Volume 3, 637. Books on the subject included the Naturalis Historia of Pliny the Elder which not only described many different minerals but also explained many of their properties. The German Renaissance specialist Georgius Agricola wrote works such as '' De re metallica'' (''On Metals'', 1556) and ''De Natura Fossilium'' (''On the Nature of Rocks'', 1546) which began the scientific approach to the subject. Systematic scientific studies of minerals and rocks developed in post-Renaissance Europe.Needham, Volume 3, 636. The modern study of mineralogy was founded on the principles of crystallography and microscopic study of rock sections with the invention of the microscope in the 17th century. Europe and the Middle East The ancient Greek writers Aristotle (384–322 BC) and Theophrastus (370� ...

Organic Compound
Some chemical authorities define an organic compound as a chemical compound that contains a carbon–hydrogen or carbon–carbon bond; others consider an organic compound to be any chemical compound that contains carbon. For example, carbon-containing compounds such as alkanes (e.g. methane ) and its derivatives are universally considered organic, but many others are sometimes considered inorganic, such as certain compounds of carbon with nitrogen and oxygen (e.g. cyanide ion , hydrogen cyanide , chloroformic acid , carbon dioxide , and carbonate ion ). Due to carbon's ability to catenate (form chains with other carbon atoms), millions of organic compounds are known. The study of the properties, reactions, and syntheses of organic compounds comprise the discipline known as organic chemistry. For historical reasons, a few classes of carbon-containing compounds (e.g., carbonate salts and cyanide salts), along with a few other exceptions (e.g., carbon dioxide, and even ...

Ammonium Chloride
Ammonium chloride is an inorganic chemical compound with the chemical formula , also written as . It is an ammonium salt of hydrogen chloride. It consists of ammonium cations and chloride anions . It is a white crystalline salt (chemistry), salt that is highly soluble in water. Solutions of ammonium chloride are mildly acidic. In its naturally occurring mineralogic form, it is known as salammoniac. The mineral is commonly formed on burning coal dumps from condensation of coal-derived gases. It is also found around some types of volcanic vents. It is mainly used as fertilizer and a flavouring agent in Salty liquorice, some types of liquorice. It is a product of the reaction of hydrochloric acid and ammonia. Production It is a product of the Solvay process used to produce sodium carbonate: :CO2 + 2 NH3 + 2 NaCl + H2O → 2 NH4Cl + Na2CO3 Not only is that method the principal one for the manufacture of ammonium chloride, but also it is used to minimize ammonia release in some ind ...

Sal Ammoniac
Salammoniac, also sal ammoniac or salmiac, is a rare naturally occurring mineral composed of ammonium chloride, NH4Cl. It forms colorless, white, or yellow-brown crystals in the Cubic (crystal system), isometric-hexoctahedral class. It has very poor Cleavage (crystal), cleavage and is brittle to conchoidal fracture. It is quite soft, with a Mohs hardness of 1.5 to 2, and it has a low specific gravity of 1.5. It is water-soluble. Salammoniac is also the archaism, archaic name for the chemical compound ammonium chloride. History Pliny the Elder, Pliny, in Book XXXI of his ''Natural History (Pliny), Natural History'', refers to a salt produced in the Roman province of Crete and Cyrenaica, Cyrenaica named ''hammoniacum'', so called because of its proximity to the nearby Temple of Amun, Jupiter Amun (Greek language, Greek Ἄμμων ''Ammon''). However, the description Pliny gives of the salt does not conform to the properties of ammonium chloride. According to Herbert Hoover, Herb ...

Arabic Grammar
Arabic grammar () is the grammar of the Arabic language. Arabic is a Semitic languages, Semitic language and its grammar has many similarities with the Semitic languages#Grammar, grammar of other Semitic languages. Classical Arabic and Modern Standard Arabic have largely the same grammar; colloquial spoken varieties of Arabic can vary in different ways. The largest differences between classical and colloquial Arabic are the loss of morpheme, morphological markings of grammatical case; changes in word order, an overall shift towards a more analytic language, analytic morphosyntax, the loss of the previous system of grammatical mood, along with the evolution of a new system; the loss of the inflected passive voice, except in a few relict varieties; restriction in the use of the Dual (grammatical number), dual number and (for most varieties) the loss of the feminine plural. Many Arabic dialects, Maghrebi Arabic in particular, also have significant vowel shifts and unusual consonant ...
