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 ...

Spanish People
Spaniards, or Spanish people, are a Romance ethnic group native to Spain. Within Spain, there are a number of national and regional ethnic identities that reflect the country's complex history, including a number of different languages, both indigenous and local linguistic descendants of the Roman-imposed Latin language, of which Spanish is the largest and the only one that is official throughout the whole country. Commonly spoken regional languages include, most notably, the sole surviving indigenous language of Iberia, Basque, as well as other Latin-descended Romance languages like Spanish itself, Catalan and Galician. Many populations outside Spain have ancestors who emigrated from Spain and share elements of a Hispanic culture. The most notable of these comprise Hispanic America in the Western Hemisphere. The Roman Republic conquered Iberia during the 2nd and 1st centuries BC. Hispania, the name given to Iberia by the Romans as a province of their Empire, became highly acc ...

Charles's Law
Charles's law (also known as the law of volumes) is an experimental gas law that describes how gases tend to expand when heated. A modern statement of Charles's law is: When the pressure on a sample of a dry gas is held constant, the Kelvin temperature and the volume will be in direct proportion. This relationship of direct proportion can be written as: :V \propto T So this means: :\frac = k, \quad \text \quad V=k T where: * is the volume of the gas, * is the temperature of the gas (measured in kelvins), and * is a non-zero constant. This law describes how a gas expands as the temperature increases; conversely, a decrease in temperature will lead to a decrease in volume. For comparing the same substance under two different sets of conditions, the law can be written as: \frac=\frac The equation shows that, as absolute temperature increases, the volume of the gas also increases in proportion. History The law was named after scientist Jacques Charles, who formulated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jacques Charles
Jacques Alexandre César Charles (November 12, 1746 – April 7, 1823) was a French inventor, scientist, mathematician, and balloonist. Charles wrote almost nothing about mathematics, and most of what has been credited to him was due to mistaking him with another Jacques Charles, also a member of the Paris Academy of Sciences, entering on May 12, 1785. He was sometimes called Charles the Geometer. Charles and the Robert brothers launched the world's first unmanned hydrogen-filled gas balloon in August 1783; then in December 1783, Charles and his co-pilot Nicolas-Louis Robert ascended to a height of about 1,800 feet (550 m) in a manned gas balloon. Their pioneering use of hydrogen for lift led to this type of balloon being named a ''Charlière'' (as opposed to a Montgolfière which used hot air). Charles's law, describing how gases tend to expand when heated, was formulated by Joseph Louis Gay-Lussac in 1802, but he credited it to unpublished work by Jacques Charles. Charles ...

Paris
Paris () is the capital and most populous city of France, with an estimated population of 2,165,423 residents in 2019 in an area of more than 105 km² (41 sq mi), making it the 30th most densely populated city in the world in 2020. Since the 17th century, Paris has been one of the world's major centres of finance, diplomacy, commerce, fashion, gastronomy, and science. For its leading role in the arts and sciences, as well as its very early system of street lighting, in the 19th century it became known as "the City of Light". Like London, prior to the Second World War, it was also sometimes called the capital of the world. The City of Paris is the centre of the Île-de-France region, or Paris Region, with an estimated population of 12,262,544 in 2019, or about 19% of the population of France, making the region France's primate city. The Paris Region had a GDP of €739 billion ($743 billion) in 2019, which is the highest in Europe. According to the Economist Intelli ...

Claude Louis Berthollet
Claude Louis Berthollet (, 9 December 1748 – 6 November 1822) was a Savoyard-French chemist who became vice president of the French Senate in 1804. He is known for his scientific contributions to theory of chemical equilibria via the mechanism of reverse chemical reactions, and for his contribution to modern chemical nomenclature. On a practical basis, Berthollet was the first to demonstrate the bleaching action of chlorine gas, and was first to develop a solution of sodium hypochlorite as a modern bleaching agent. Biography Claude Louis Berthollet was born in Talloires, near Annecy, then part of the Duchy of Savoy, in 1749. He started his studies at Chambéry and then in Turin where he graduated in medicine. Berthollet's great new developments in works regarding chemistry made him, in a short period of time, an active participant of the Academy of Science in 1780. Berthollet, along with Antoine Lavoisier and others, devised a chemical nomenclature, or a system of name ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pierre Adet
Pierre-Auguste Adet (17 May 1763 Nevers – 19 March 1834 Paris) was a French scientist, politician, and diplomat. He worked with Lavoisier on a new chemical notation system, and was secretary to the scientific periodical ''Annales de chimie'', founded in 1789. He proved that glacial acetic acid and vinegar acetic acid were the same substance. In 1796, Adet was elected a member of the American Philosophical Society. He was secretary to the Minister of the Navy and the Colonies, Jean Dalbarade. He was commissioner to Saint-Domingue. He later became French ambassador to the United States, He sent Georges-Henri-Victor Collot on a reconnaissance of the Ohio River, and Mississippi River. In 1803, he was Prefect of the Nièvre ''département''. In 1809, he was a member of the Corps législatif The was a part of the French legislature during the French Revolution and beyond.

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 ...

Louis-Bernard Guyton De Morveau
Louis-Bernard Guyton, Baron de Morveau (also Louis-Bernard Guyton-Morveau after the French Revolution; 4 January 1737 – 2 January 1816) was a French chemist, politician, and aeronaut. He is credited with producing the first systematic method of chemical nomenclature. Early career Guyton de Morveau was born in Dijon, where he served as a lawyer, then '' avocat général'', of the Dijon ''parlement''. In 1773, already interested in chemistry, he proposed use of "muriatic acid gas" for fumigation of buildings and as a result is sometimes given credit for having suggested chlorine in this use. However, chlorine was not well characterized at that time, and hydrogen chloride (made by reacting sodium chloride Sodium chloride , commonly known as salt (although sea salt also contains other chemical salts), is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions. With molar masses of 22.99 and 35.45 g ... and sulfuric acid) was ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthur Young (writer)
Arthur Young (11 September 1741 – 12 April 1820) was an English agriculturist. Not himself successful as a farmer, he built on connections and activities as a publicist a substantial reputation as an expert on agricultural improvement. After the French Revolution of 1789, his views on its politics carried weight as an informed observer, and he became an important opponent of British reformers. Young is considered a major English writer on agriculture, although he is best known as a social and political observer. Also read widely were his ''Tour in Ireland'' (1780) and ''Travels in France'' (1792). Early life Young was born in 1741 at Whitehall, London, the second son of Anna Lucretia Coussmaker, and her husband Arthur Young, who was rector of Bradfield Combust in Suffolk and chaplain to Arthur Onslow. After attending school at Lavenham from 1748, he was in 1758 placed at Messrs Robertson, a mercantile house in King's Lynn. His sister Elizabeth Mary, who married John Thomlinso ...

Windsor, Berkshire
Windsor is a historic market town and unparished area in the Royal Borough of Windsor and Maidenhead in Berkshire, England. It is the site of Windsor Castle, one of the official residences of the British monarch. The town is situated west of Charing Cross, central London, southeast of Maidenhead, and east of the county town of Reading. It is immediately south of the River Thames, which forms its boundary with its smaller, ancient twin town of Eton. The village of Old Windsor, just over to the south, predates what is now called Windsor by around 300 years; in the past Windsor was formally referred to as New Windsor to distinguish the two. Etymology ''Windlesora'' is first mentioned in the ''Anglo-Saxon Chronicle.'' (The settlement had an earlier name but this is unknown.) The name originates from old English ''Windles-ore'' or ''winch by the riverside''.South S.R., ''The Book of Windsor'', Barracuda Books, 1977.
