Giuseppe Domenico Botto
Giuseppe Domenico Botto (4 April 1791 – 20 March 1865) was an Italian physicist. Born at Moneglia, he studied at the University of Genoa and the École Polytechnique in Paris. The chair of General and Experimental Physics was assigned to G.D Botto in 1828. Experimental work was dedicated to magnetic, thermal, and chemical effects of electrical currents and induction of currents. In 1830 Botto described in a note a prototype electric motor on which he was working and published a description of it in a Memoria titled "Machine Loco-motive mise en mouvement par l'électro-magnétisme" to the Academy of Turin around 1836. A device built on the basis of his description was part of the collection of scientific instruments of the Grand Duke of Tuscany, which is now kept at the Institute and Museum of History of Science in Florence. In the following years he published more work on improving efficiency of electric motors. Botto experimented with electrolysis of water using a man ...

Physicist
A physicist is a scientist who specializes in the field of physics, which encompasses the interactions of matter and energy at all length and time scales in the physical universe. Physicists generally are interested in the root or ultimate causes of phenomena, and usually frame their understanding in mathematical terms. Physicists work across a wide range of research fields, spanning all length scales: from sub-atomic and particle physics, through biological physics, to cosmological length scales encompassing the universe as a whole. The field generally includes two types of physicists: experimental physicists who specialize in the observation of natural phenomena and the development and analysis of experiments, and theoretical physicists who specialize in mathematical modeling of physical systems to rationalize, explain and predict natural phenomena. Physicists can apply their knowledge towards solving practical problems or to developing new technologies (also known as applie ...

Leopoldo Nobili
Leopoldo Nobili, born on 5 July 1784 in Trassilico (Toscana) and died on 22 August 1835 in Florence, was an Italian physicist who invented a number of instruments critical to investigating thermodynamics and electrochemistry. Born Trassilico, Garfagnana, after attending the Military Academy of Modena he became an artillery officer. He was awarded the Légion d'honneur for his service in Napoleon's invasion of Russia. In 1825 he developed the astatic galvanometer. He worked with Macedonio Melloni on the ''thermomultiplier'', a combination of thermopile and galvanometer, before being appointed professor of physics at the Reale Museo di Fisica e Storia Naturale (Royal Museum of Physics and Natural History) in Florence where he worked with Vincenzo Antinori on electromagnetic induction Electromagnetic or magnetic induction is the production of an electromotive force (emf) across an electrical conductor in a changing magnetic field.

19th-century Italian Physicists
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the large S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
People From Moneglia
A person (plural, : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal obligation, legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its us ...

Chiavari
Chiavari (; lij, Ciävai ) is a comune (municipality) in the Metropolitan City of Genoa, in Italy. It has about 28,000 inhabitants. It is situated near the river Entella. History Pre-Roman and Roman Era A pre-Roman necropolis, which dates from the 8th to 7th century BC, has been uncovered in the area where Chiavari is located now. Chiavari grew up on the traces of a Roman camp on the Via Aurelia. Medieval Era A castle was constructed in 1147. The old town contains numerous arcades and buildings from the 13th century, including a castle, several mansions, and the nearby Church of San Salvatore di Lavagna, which was founded in 1224 by Innocent IV. The cathedral was rebuilt in 1613. Known famously as a center of ancient humanistic tradition, Chiavari has a public library with a collection of manuscripts and incunabula. After the discovery of the conspiracy of the Fieschi, in 1542, and the capture of Chiavari by the Counts of Lavagna, the town suffered much, being associated wi ...

Thermocouple
A thermocouple, also known as a "thermoelectrical thermometer", is an electrical device consisting of two dissimilar electrical conductors forming an electrical junction. A thermocouple produces a temperature-dependent voltage as a result of the Seebeck effect, and this voltage can be interpreted to measure temperature. Thermocouples are widely used as temperature sensors. Commercial thermocouples are inexpensive, interchangeable, are supplied with standard connectors, and can measure a wide range of temperatures. In contrast to most other methods of temperature measurement, thermocouples are self powered and require no external form of excitation. The main limitation with thermocouples is accuracy; system errors of less than one degree Celsius (°C) can be difficult to achieve. Thermocouples are widely used in science and industry. Applications include temperature measurement for kilns, gas turbine exhaust, diesel engines, and other industrial processes. Thermocouples are also ...

Michael Faraday
Michael Faraday (; 22 September 1791 – 25 August 1867) was an English scientist who contributed to the study of electromagnetism and electrochemistry. His main discoveries include the principles underlying electromagnetic induction, diamagnetism and electrolysis. Although Faraday received little formal education, he was one of the most influential scientists in history. It was by his research on the magnetic field around a conductor carrying a direct current that Faraday established the concept of the electromagnetic field in physics. Faraday also established that magnetism could affect rays of light and that there was an underlying relationship between the two phenomena.. the 1911 Encyclopædia Britannica. He similarly discovered the principles of electromagnetic induction, diamagnetism, and the laws of electrolysis. His inventions of electromagnetic rotary devices formed the foundation of electric motor technology, and it was largely due to his efforts t ...

Vincenzo Antinori
Vincenzo Antinori (1792–1865) was a science administrator in Italy. From 1829 to 1859, Antinori was director of the Regal Museum of Physics and Natural History in Florence where he worked with Leopoldo Nobili on electromagnetic induction. He had originally attracted Nobili to Florence to teach physics, as he had Giovanni Battista Amici to teach astronomy. He was one of the promoters of the Congress of Italian Scientists in Pisa in 1839 and in Florence in 1841 and was responsible for bringing permanence, order and security to the Italian legacy of meteorological data by founding the Italian Meteorological Archive. Antinori was a member of the Accademia della Crusca and wrote many entries for the Crusca dictionary on scientific topics. He had a particular interest in preserving and interpreting documents and artefacts from the work of Galileo Galilei and his followers. Bibliografía: "Antonio Meucci e la città di Firenze.

Electrolysis Of Water
Electrolysis of water, also known as electrochemical water splitting, is the process of using electricity to decompose water into oxygen and hydrogen gas by electrolysis. Hydrogen gas released in this way can be used as hydrogen fuel, or remixed with the oxygen to create oxyhydrogen gas, which is used in welding and other applications. Electrolysis of water requires a minimum potential difference of 1.23 volts, though at that voltage external heat is required. E lectrolysis is rarely used in industrial applications since hydrogen can be produced less expensively from fossil fuels. History In 1789, Jan Rudolph Deiman and Adriaan Paets van Troostwijk used an electrostatic machine to make electricity that was discharged on gold electrodes in a Leyden jar with water. In 1800 Alessandro Volta invented the voltaic pile, and a few weeks later English scientists William Nicholson and Anthony Carlisle used it to electrolyse water. In 1806 Humphry Davy reported the results of ext ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
