Torgut
The Torghut ( Mongolian: Торгууд, , Torguud), , "Guardsman" are one of the four major subgroups of the Four Oirats. The Torghut nobles traced its descent to the Keraite ruler Tooril; also many Torghuts descended from the Keraites. History They might have been kheshigs of the Great Khans before Kublai Khan. The Torghut clan first appeared as an Oirat group in the mid-16th century. After the collapse of the Four Oirat Alliance, the majority of the Torghuts under Kho Orluk separated from other Oirat groups and moved west to the Volga region in 1630, forming the core of the Kalmyks. A few Torghut nobles followed Toro Baikhu Gushi Khan to Qinghai Lake (Koke Nuur), becoming part of the so-called Upper Mongols. In 1698, 500 Torghuts went on pilgrimage to Tibet but were unable to return. Hence, they were resettled in Ejin River by the Kangxi Emperor of China's Qing dynasty. In 1699 15,000 Torghut households returned from the Volga region to Dzungaria where they joined the Khoit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Statistician
A statistician is a person who works with theoretical or applied statistics. The profession exists in both the private and public sectors. It is common to combine statistical knowledge with expertise in other subjects, and statisticians may work as employees or as statistical consultants. Nature of the work According to the United States Bureau of Labor Statistics, as of 2014, 26,970 jobs were classified as ''statistician'' in the United States. Of these people, approximately 30 percent worked for governments (federal, state, or local). As of October 2021, the median pay for statisticians in the United States was $92,270. Additionally, there is a substantial number of people who use statistics and data analysis in their work but have job titles other than ''statistician'', such as actuaries, applied mathematicians, economist An economist is a professional and practitioner in the social science discipline of economics. The individual may also study, develop, and apply ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
English People
The English people are an ethnic group and nation native to England, who speak the English language in England, English language, a West Germanic languages, West Germanic language, and share a common history and culture. The English identity is of History of Anglo-Saxon England, Anglo-Saxon origin, when they were known in Old English as the ('race or tribe of the Angles'). Their ethnonym is derived from the Angles, one of the Germanic peoples who migrated to Great Britain around the 5th century AD. The English largely descend from two main historical population groups the West Germanic tribes (the Angles, Saxons, Jutes and Frisians) who settled in southern Britain following the withdrawal of the Ancient Rome, Romans, and the Romano-British culture, partially Romanised Celtic Britons already living there.Martiniano, R., Caffell, A., Holst, M. et al.

Gregory King
Gregory King (15 December 1648 – 29 August 1712) was an English genealogist, engraver and statistician. Life Gregory King was born at Lichfield, England. His father was a surveyor and landscape gardener. Gregory was a very bright boy and his father used him as an assistant in his surveying work. At 14 Gregory became a clerk to William Dugdale the antiquary and herald, i.e. student of heraldry. King later (1667–69) worked for Lord Hatton, who was forming a collection of the arms of the nobility. When this project collapsed, he went to work for the dowager Lady Gerard at Sandon, Staffordshire as steward, auditor and secretary (1670–72). She was the widow of Charles Gerard, 4th Baron Gerard, and remarried in 1673. In 1672 King moved to London to work as an engraver for the printer John Ogilby; he also did surveying work and engraved maps. In 1677 he was appointed Rouge Dragon Pursuivant of Arms in Ordinary in the College of Arms. He became Lancaster Herald of Arms in Ord ...

Law Of Conservation Of Mass
In physics and chemistry, the law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed. Therefore, the quantity of mass is conserved over time. The law implies that mass can neither be created nor destroyed, although it may be rearranged in space, or the entities associated with it may be changed in form. For example, in chemical reactions, the mass of the chemical components before the reaction is equal to the mass of the components after the reaction. Thus, during any chemical reaction and low-energy thermodynamic processes in an isolated system, the total mass of the reactants, or starting materials, must be equal to the mass of the products. The concept of mass conservation is widely used in many fields such as chemistry, mechanics, and fluid dynamics. Historic ...

Chemistry
Chemistry is the science, scientific study of the properties and behavior of matter. It is a natural science that covers the Chemical element, elements that make up matter to the chemical compound, compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a Chemical reaction, reaction with other Chemical substance, substances. Chemistry also addresses the nature of chemical bonds in chemical compounds. In the scope of its subject, chemistry occupies an intermediate position between physics and biology. It is sometimes called the central science because it provides a foundation for understanding both Basic research, basic and Applied science, applied scientific disciplines at a fundamental level. For example, chemistry explains aspects of plant growth (botany), the formation of igneous rocks (geology), how atmospheric ozone is formed and how environmental pollutants are degraded (ecology), the properties ...

Alchemy
Alchemy (from Arabic: ''al-kīmiyā''; from Ancient Greek: χυμεία, ''khumeía'') is an ancient branch of natural philosophy, a philosophical and protoscientific tradition that was historically practiced in China, India, the Muslim world, and Europe. In its Western form, alchemy is first attested in a number of pseudepigraphical texts written in Greco-Roman Egypt during the first few centuries AD.Principe, Lawrence M. The secrets of alchemy'. University of Chicago Press, 2012, pp. 9–14. Alchemists attempted to purify, mature, and perfect certain materials. Common aims were chrysopoeia, the transmutation of "base metals" (e.g., lead) into "noble metals" (particularly gold); the creation of an elixir of immortality; and the creation of panaceas able to cure any disease. The perfection of the human body and soul was thought to result from the alchemical ''magnum opus'' ("Great Work"). The concept of creating the philosophers' stone was variously connected with all of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Franciscus Mercurius Van Helmont
Franciscus Mercurius van Helmont (baptised 20 October 1614 – December 1698) was a Flemish alchemist and writer, the son of Jan Baptist van Helmont. He is now best known for his publication in the 1640s of his father's pioneer works on chemistry, which link the origins of the science to the study of alchemy. From his early work as a physician, he became a kabbalist and together with Henry More of the Cambridge Platonists he annotated Christian Knorr von Rosenroth's translations of kabbalist texts. Contacts and movement He led an itinerant life in wanderings in Europe, an adjective already applied to him by Anthony Ashley-Cooper, 3rd Earl of Shaftesbury in his 1711 ''Characteristicks of Men, Manners, Opinions, Times''. He self-identified as a "wandering eremite". Franciscus van Helmont had important groups of contacts in the Netherlands, where he knew Adam Boreel and Serrarius, and later in life, in 'the Lantern', the circle around the Rotterdam merchant Benjamin Furly that incl ...

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 ...

Lodewijk Elzevir
Lodewijk Elzevir (c. 1540, Leuven – 4 February 1617, Leiden), originally ''Lodewijk or Louis Elsevier or Elzevier'', was a printer, born in the city of Leuven (today in Belgium, then part of the Habsburg Netherlands or Spanish Netherlands). He was the founder of the House of Elzevir, which printed, for example, "Two New Sciences", a work of Galileo, at a time when his work was suppressed for religious reasons. Although the House of Elzevir ceased publishing in 1712, the modern Dutch Elsevier company was founded in 1880 and took its name from the historic Dutch publishing house. Biography Elzevir, son of Hans Helschevier, was born in Leuven and started his career as a bookbinder at the printing shop of Christoffel Plantijn in Antwerp. In 1563 he married Maijke de Verdeijen Verbois in Antwerp, where his first two sons were born. He moved to Wesel before 1570, to Douai before 1575 and settled in Leiden before 1580.
