Science
Science is a systematic endeavor that builds and organizes knowledge in the form of testable explanations and predictions about the universe. Science may be as old as the human species, and some of the earliest archeological evidence for scientific reasoning is tens of thousands of years old. The earliest written records in the history of science come from Ancient Egypt and Mesopotamia in around 3000 to 1200 BCE. Their contributions to mathematics, astronomy, and medicine entered and shaped Greek natural philosophy of classical antiquity, whereby formal attempts were made to provide explanations of events in the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but was preserved in the Muslim world during the Islamic Golden Age and later by the efforts of Byzantine Greek scholars who brought Greek ...

Abraham Gotthelf Kästner
Abraham Gotthelf Kästner (27 September 1719 – 20 June 1800) was a German mathematician and epigrammatist. He was known in his professional life for writing textbooks and compiling encyclopedias rather than for original research. Georg Christoph Lichtenberg was one of his doctoral students, and admired the man greatly. He became most well known for his epigrammatic poems. The crater Kästner on the Moon is named after him. Life Kästner was the son of law professor Abraham Kästner. He married Anna Rosina Baumann in 1757 after a 12-year engagement. She died on 4 March 1758, less than a year later, of a lung disease. Later Kästner had a daughter Catharine with his cleaning lady. Kästner studied law, philosophy, physics, mathematics and metaphysics in Leipzig from 1731, and was appointed a Notary in 1733. He gained his habilitation from the University of Leipzig in 1739, and lectured there in mathematics, philosophy, logic and law, becoming an associate professor in 17 ...

James Sutherland (botanist)
James Sutherland (c. 1639–1719) was the first Professor of Physic (Botany) at the University of Edinburgh, from 1676 to 1705. He was intendant of the Physic Garden (later to evolve into the Royal Botanic Garden on a new site), and his innovative publication ''Hortus Medicus Edinburgensis'' placed Scotland at the forefront of European botany. He was also a renowned coin collector.https://www.britnumsoc.org/publications/Digital%20BNJ/pdfs/1996_BNJ_66_8.pdf Although known for his abilities as a herbalist and his enthusiasm for plants, Sutherland was just a youth when first recruited by Dr (later Sir) Robert Sibbald and Dr (later Sir) Andrew Balfour to take care of their burgeoning plant collection. Initially this was at the Palace of Holyroodhouse garden, but in 1675, when land was acquired in the grounds of Trinity Hospital, over which Edinburgh Waverley station has now been built, Sutherland was appointed Intendant of the (Town) Physic Garden. Within eight years Sutherland ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Porcelain
Porcelain () is a ceramic material made by heating substances, generally including materials such as kaolinite, in a kiln to temperatures between . The strength and translucence of porcelain, relative to other types of pottery, arises mainly from vitrification and formation of the mineral mullite within the body at these high temperatures. Though definitions vary, porcelain can be divided into three main categories: hard-paste, soft-paste, and bone china. The category that an object belongs to depends on the composition of the paste used to make the body of the porcelain object and the firing conditions. Porcelain slowly evolved in China and was finally achieved (depending on the definition used) at some point about 2,000 to 1,200 years ago; it slowly spread to other East Asian countries, then to Europe, and eventually to the rest of the world. Its manufacturing process is more demanding than that for earthenware and stoneware, the two other main types of pottery, and it ...

Alchemist
Alchemy (from Arabic: ''al-kīmiyā''; from Ancient Greek: χυμεία, ''khumeía'') is an ancient branch of natural philosophy, a philosophical and protoscience, protoscientific tradition that was historically practiced in Chinese alchemy, China, Rasayana, India, the Alchemy and chemistry in medieval Islam, Muslim world, and Europe. In its Western form, alchemy is first attested in a number of pseudepigraphical texts written in Egypt (Roman province), 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 life, elixir of immortality; and the creation of Panacea (medicine), panaceas able to cure any disease. The perfection of the human body and soul was thought to result f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Friedrich Böttger
Johann Friedrich Böttger (also Böttcher or Böttiger; 4 February 1682 – 13 March 1719) was a German alchemist. Böttger was born in Schleiz and died in Dresden. He is normally credited with being the first European to discover the secret of the creation of hard-paste porcelain in 1708, but it has also been claimed that English manufacturers or Ehrenfried Walther von Tschirnhaus produced porcelain first. Certainly, the Meissen factory, established 1710, was the first to produce porcelain in Europe in large quantities and since the recipe was kept a trade secret by Böttger for his company, experiments continued elsewhere throughout Europe. Biography On Thursday, February 5, 1682, Johann Friedrich Böttger was baptized in Schleiz as the third child of his parents. His father was a mint master in Schleiz. His mother was the daughter of the Magdeburg councilor Pflug. In 1682 the family moved to Magdeburg. In the same year his father died. In 1685 his mother married the also wido ...

John Flamsteed
John Flamsteed (19 August 1646 – 31 December 1719) was an English astronomer and the first Astronomer Royal. His main achievements were the preparation of a 3,000-star catalogue, ''Catalogus Britannicus'', and a star atlas called ''Atlas Coelestis'', both published posthumously. He also made the first recorded observations of Uranus, although he mistakenly catalogued it as a star, and he laid the foundation stone for the Royal Greenwich Observatory. Life Flamsteed was born in Denby, Derbyshire, England, the only son of Stephen Flamsteed and his first wife, Mary Spadman. He was educated at the free school of Derby and at Derby School, in St Peter's Churchyard, Derby, near where his father carried on a malting business. At that time, most masters of the school were Puritans. Flamsteed had a solid knowledge of Latin, essential for reading the scientific literature of the day, and a love of history, leaving the school in May 1662.Birks, John L.
