Giovanni Antonio Giobert
Giovanni Antonio Giobert also known as Jean-Antoine Giobert (27 October 1761 in Mongardino - 14 September 1834 in Millefiori) was an Italian chemist and mineralogist who studied magnetism, galvanism, and agricultural chemistry. He introduced Antoine Lavoisier's theories to Italy, and built a phosphorus-based eudiometer sufficiently sensitive to measure atmospheric carbon dioxide and oxygen. He identified the correct composition of the mineral Gioberite, a form of magnesite (MgCO3) found in the Piedmont area. He was made a knight (Cavaliere) for his work on the chemistry of indigo dyes. Early life Giovanni Antonio Giobert was born on 27 October 1761 in Mongardino near Asti, to Spirito and Anna Gugalin. He was educated by Abbot G. B. Lovizzolo, studying the physical sciences and chemistry, and was apprenticed in pharmacies in Asti and Turin. Science In his early twenties, Giobert focused his studies on the application of chemistry in agriculture and industry. He became a member of ...

Società Italiana Della Scienza
''Società'' ( Italian: ''Society'') was an Italian communist cultural magazine published in Italy between 1945 and 1961. History and profile ''Società'' was founded as a quarterly magazine in Florence in 1945. The founders were Ranuccio Bianchi Bandinelli, Cesare Luporini and Romano Bilenchi. Bandinelli also directed the magazine. In 1948 the magazine became closer to the Italian Communist Party (PCI), but was not published by the party. The headquarters was later moved to Rome, and in 1954 its frequency was switched to bimonthly. ''Società'' featured Italian fiction and poetry and occasionally included some essays on the theater and the cinema. It was one of the publications read by the Italian intellectuals, who had Gramscian views. Giorgio Napolitano Giorgio Napolitano (; born 29 June 1925) is an Italian politician who served as president of Italy from 2006 to 2015, the first Italian president to be re-elected to the presidency.

François Sulpice Beudant
François Sulpice Beudant (5 September 1787 – 10 December 1850), was a French mineralogist and geologist. The mineral beudantite was named after him. Life He was born in Paris. He was educated at the Ecole Polytechnique and Ecole Normale, and in 1811 was appointed professor of mathematics at the lycée of Avignon. Thence he was called, in 1813, to the lycée of Marseilles to fill the post of professor of physics, where he carried out the first measurements of the speed of sound in seawater. In the following year the royal mineralogical cabinet was committed to his charge to be conveyed into England, and from that time his attention was directed principally towards geology and cognate sciences. In 1817 he published a paper on the phenomena of crystallization, treating especially of the variety of forms assumed by the same mineral substance. In 1818 he undertook, at the expense of the French government, a geological journey through Hungary, and the results of his researches ...

Joseph Louis Gay-Lussac
Joseph Louis Gay-Lussac (, , ; 6 December 1778 – 9 May 1850) was a French chemist and physicist. He is known mostly for his discovery that water is made of two parts hydrogen and one part oxygen (with Alexander von Humboldt), for two laws related to gases, and for his work on alcohol–water mixtures, which led to the degrees Gay-Lussac used to measure alcoholic beverages in many countries. Biography Gay-Lussac was born at Saint-Léonard-de-Noblat in the present-day department of Haute-Vienne. The father of Joseph Louis Gay, Anthony Gay, son of a doctor, was a lawyer and prosecutor and worked as a judge in Noblat Bridge. Father of two sons and three daughters, he owned much of the Lussac village and usually added the name of this hamlet of the Haute-Vienne to his name, following a custom of the Ancien Régime. Towards the year 1803, father and son finally adopted the name Gay-Lussac. During the Revolution, on behalf of the Law of Suspects, his father, former king's atto ...

John Dalton
John Dalton (; 5 or 6 September 1766 – 27 July 1844) was an English chemist, physicist and meteorologist. He is best known for introducing the atomic theory into chemistry, and for his research into colour blindness, which he had. Colour blindness is known as ''Daltonism'' in several languages, being named after him. Early life John Dalton was born into a Quaker family in Eaglesfield, near Cockermouth, in Cumberland, England. His father was a weaver. He received his early education from his father and from Quaker John Fletcher, who ran a private school in the nearby village of Pardshaw Hall. Dalton's family was too poor to support him for long and he began to earn his living, from the age of ten, in the service of wealthy local Quaker Elihu Robinson. Early career When he was 15, Dalton joined his older brother Jonathan in running a Quaker school in Kendal, Westmorland, about from his home. Around the age of 23, Dalton may have considered studying law or medicin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Humphry Davy
Sir Humphry Davy, 1st Baronet, (17 December 177829 May 1829) was a British chemist and inventor who invented the Davy lamp and a very early form of arc lamp. He is also remembered for isolating, by using electricity, several elements for the first time: potassium and sodium in 1807 and calcium, strontium, barium, magnesium and boron the following year, as well as for discovering the elemental nature of chlorine and iodine. Davy also studied the forces involved in these separations, inventing the new field of electrochemistry. Davy is also credited to have been the first to discover clathrate hydrates in his lab. In 1799 he experimented with nitrous oxide and was astonished at how it made him laugh, so he nicknamed it "laughing gas" and wrote about its potential anaesthetic properties in relieving pain during surgery. Davy was a baronet, President of the Royal Society (PRS), Member of the Royal Irish Academy (MRIA), Fellow of the Geological Society (FGS), and a member ...

Spallanzani
Lazzaro Spallanzani (; 12 January 1729 – 11 February 1799) was an Italian Catholic priest (for which he was nicknamed Abbé Spallanzani), biologist and physiologist who made important contributions to the experimental study of bodily functions, animal reproduction, and animal echolocation. His research on biogenesis paved the way for the downfall of the theory of spontaneous generation, a prevailing idea at the time that organisms develop from inanimate matters, though the final death blow to the idea was dealt by French scientist Louis Pasteur a century later. His most important works were summed up in his book ''Experiencias Para Servir a La Historia de La Generación De Animales y Plantas'' (''Experiences to Serve to the History of the Generation of Animals and Plants''), published in 1786. Among his contributions were experimental demonstrations of fertilisation between ova and spermatozoa, and ''in vitro'' fertilisation''.'' Biography Spallanzani was born in Scandia ...

Eudiometry
A eudiometer is a laboratory device that measures the change in volume of a gas mixture following a physical or chemical change. Description Depending on the reaction being measured, the device can take a variety of forms. In general, it is similar to a graduated cylinder, and is most commonly found in two sizes: 50 mL and 100 mL. It is closed at the top end with the bottom end immersed in water or mercury. The liquid traps a sample of gas in the cylinder, and the graduation allows the volume of the gas to be measured. For some reactions, two platinum wires (chosen for their non-reactivity) are placed in the sealed end so an electric spark can be created between them. The electric spark can initiate a reaction in the gas mixture and the graduation on the cylinder can be read to determine the change in volume resulting from the reaction. The use of the device is quite similar to the original barometer, except that the gas inside displaces some of the liquid that is used. Hist ...

Phlogiston Theory
The phlogiston theory is a superseded scientific theory that postulated the existence of a fire-like element called phlogiston () contained within combustible bodies and released during combustion. The name comes from the Ancient Greek (''burning up''), from (''flame''). The idea was first proposed in 1667 by Johann Joachim Becher and later put together more formally by Georg Ernst Stahl. Phlogiston theory attempted to explain chemical processes such as combustion and rusting, now collectively known as oxidation. It was challenged by the concomitant weight increase, and was abandoned before the end of the 18th century following experiments by Antoine Lavoisier and others. Phlogiston theory led to experiments which ultimately concluded with the discovery of oxygen. Theory Phlogiston theory states that ''phlogisticated'' substances contain phlogiston and that they ''dephlogisticate'' when burned, releasing stored phlogiston which is absorbed by the air. Growing plants then absor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
