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 ...

Antoine Lavoisier
Antoine-Laurent de Lavoisier ( , ; ; 26 August 17438 May 1794), When reduced without charcoal, it gave off an air which supported respiration and combustion in an enhanced way. He concluded that this was just a pure form of common air and that it was the air itself "undivided, without alteration, without decomposition" which combined with metals on calcination. After returning from Paris, Priestley took up once again his investigation of the air from mercury calx. His results now showed that this air was not just an especially pure form of common air but was "five or six times better than common air, for the purpose of respiration, inflammation, and ... every other use of common air". He called the air dephlogisticated air, as he thought it was common air deprived of its phlogiston. Since it was therefore in a state to absorb a much greater quantity of phlogiston given off by burning bodies and respiring animals, the greatly enhanced combustion of substances and the greater e ...

Henry Maudslay
Henry Maudslay ( pronunciation and spelling) (22 August 1771 – 14 February 1831) was an English machine tool innovator, tool and die maker, and inventor. He is considered a founding father of machine tool technology. His inventions were an important foundation for the Industrial Revolution. Maudslay's invention of a metal lathe to cut metal, circa 1800, enabled the manufacture of standard screw thread sizes. Standard screw thread sizes allowed interchangeable parts and the development of mass production. Early life Maudslay was the fifth of seven children of Henry Maudslay, a wheelwright in the Royal Engineers, and Margaret (''nee'' Whitaker), the young widow of Joseph Laundy. His father was wounded in action and so in 1756 became an 'artificer' at the Royal Arsenal, Woolwich (then in Kent), where he remained until 1776 and died in 1780. The family lived in an alley that no longer exists, off Beresford Square, between Powis Street and Beresford Street. Career Maudslay be ...

Inventor
An invention is a unique or novel device, method, composition, idea or process. An invention may be an improvement upon a machine, product, or process for increasing efficiency or lowering cost. It may also be an entirely new concept. If an idea is unique enough either as a stand alone invention or as a significant improvement over the work of others, it can be patented. A patent, if granted, gives the inventor a proprietary interest in the patent over a specific period of time, which can be licensed for financial gain. An inventor creates or discovers an invention. The word ''inventor'' comes from the Latin verb ''invenire'', ''invent-'', to find. Although inventing is closely associated with science and engineering, inventors are not necessarily engineers or scientists. Due to advances in artificial intelligence, the term "inventor" no longer exclusively applies to an occupation (see human computers). Some inventions can be patented. The system of patents was established ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Richard Trevithick
Richard Trevithick (13 April 1771 – 22 April 1833) was a British inventor and mining engineer. The son of a mining captain, and born in the mining heartland of Cornwall, Trevithick was immersed in mining and engineering from an early age. He was an early pioneer of steam-powered road and rail transport, and his most significant contributions were the development of the first high-pressure steam engine and the first working railway steam locomotive. The world's first locomotive-hauled railway journey took place on 21 February 1804, when Trevithick's unnamed steam locomotive hauled a train along the tramway of the Penydarren Ironworks, in Merthyr Tydfil, Wales. Turning his interests abroad Trevithick also worked as a mining consultant in Peru and later explored parts of Costa Rica. Throughout his professional career he went through many ups and downs and at one point faced financial ruin, also suffering from the strong rivalry of many mining and steam engineers of the day.

Matthew Raper
Matthew Raper (1705–1778) was a British astronomer, mathematician, and scholar in various fields. He published papers on diverse subjects, including ancient Greek coinage and Roman currency, as well as their measures and their history from Greek and Latin texts. Raper was elected to the Royal Society on 30 May 1754 and was awarded the Copley Medal in 1771 for a paper "Inquiry into the Value of the ancient Greek and Roman Money." He translated ''Dissertation on the Gipseys'' from Heinrich Grellman's German original and wrote diverse papers such as "An Enquiry into the Measure of the Roman Foot" (1760) and "Observations on the Moon's Eclipse, March 17., and the Sun's Eclipse, April 1, 1764." Matthew Raper's father was also named Matthew and left him the Manor of Thorley, Hertfordshire __NOTOC__ Thorley is a village and civil parish in East Hertfordshire district of Hertfordshire, England.

Copley Medal
The Copley Medal is an award given by the Royal Society, for "outstanding achievements in research in any branch of science". It alternates between the physical sciences or mathematics and the biological sciences. Given every year, the medal is the oldest Royal Society medal awarded and the oldest surviving scientific award in the world, having first been given in 1731 to Stephen Gray (scientist), Stephen Gray, for "his new Electrical Experiments: – as an encouragement to him for the readiness he has always shown in obliging the Society with his discoveries and improvements in this part of Natural Knowledge". __TOC__ History The medal was created following a donation of Pound sterling, £100 to be used for carrying out experiments by Sir Godfrey Copley, 2nd Baronet, Sir Godfrey Copley, for which the interest on the amount was used for several years. The conditions for the medal have been changed several times; in 1736, it was suggested that "a medal or other honorary prize s ...
