1782 In Science
The year 1782 in science and technology included many events, some of which are listed here. Aviation * December 14 – The Montgolfier brothers first test fly a hot air balloon; it floats nearly . Biology * Jesuit abbot Juan Ignacio Molina publishes ''Saggio sulla Storia Naturale del Chili'' in Spain, the first account of the natural history of his native Chile, describing many species to science for the first time (e.g., ''Araucaria araucana''). Chemistry * Telluride minerals are first discovered in a gold mine in Kleinschlatten, Transylvania (modern-day Zlatna, Romania) by Austrian mineralogist Franz-Joseph Müller von Reichenstein. * Winter 1782–83 – Antoine Lavoisier and Pierre-Simon Laplace begin to use the world's first ice calorimeter to determine the heat evolved in various chemical changes (calculations based on Joseph Black's prior discovery of latent heat), marking the foundation of thermochemistry. Medicine * May – First patient admitted to Montrose Luna ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pierre-Simon Laplace
Pierre-Simon, Marquis de Laplace (; ; 23 March 1749 – 5 March 1827) was a French polymath, a scholar whose work has been instrumental in the fields of physics, astronomy, mathematics, engineering, statistics, and philosophy. He summarized and extended the work of his predecessors in his five-volume Traité de mécanique céleste, ''Mécanique céleste'' (''Celestial Mechanics'') (1799–1825). This work translated the geometric study of classical mechanics to one based on calculus, opening up a broader range of problems. Laplace also popularized and further confirmed Isaac Newton, Sir Isaac Newton's work. In statistics, the Bayesian probability, Bayesian interpretation of probability was developed mainly by Laplace. Laplace formulated Laplace's equation, and pioneered the Laplace transform which appears in many branches of mathematical physics, a field that he took a leading role in forming. The Laplace operator, Laplacian differential operator, widely used in mathematic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Young's Modulus
Young's modulus (or the Young modulus) is a mechanical property of solid materials that measures the tensile or compressive stiffness when the force is applied lengthwise. It is the modulus of elasticity for tension or axial compression. Young's modulus is defined as the ratio of the stress (force per unit area) applied to the object and the resulting axial strain (displacement or deformation) in the linear elastic region of the material. Although Young's modulus is named after the 19th-century British scientist Thomas Young, the concept was developed in 1727 by Leonhard Euler. The first experiments that used the concept of Young's modulus in its modern form were performed by the Italian scientist Giordano Riccati in 1782, pre-dating Young's work by 25 years. The term modulus is derived from the Latin root term '' modus'', which means ''measure''. Definition Young's modulus, E, quantifies the relationship between tensile or compressive stress \sigma (force per unit ar ...

Giordano Riccati
Giordano Riccati or Jordan Riccati (25 February, 1709 – 20 July, 1790) was an Italian mathematician and physicist. Biography Giordano Riccati was born in 1709 in Castelfranco Veneto, a small town about 30 km north of Padua. He was the brother of Vincenzo Riccati and the fifth son of the theoretical mechanician Jacopo Riccati. He began his studies at the College of St. Francis Xavier in Bologna, under the guidance of Francesco Saverio Quadrio and Luigi Marchenti, a pupil of the French mathematician Pierre Varignon. In 1727, he returned to Castelfranco, where his father taught him geometry, trigonometry, calculus, statics and dynamics. He then moved to the University of Padua and attended Giovanni Poleni's lessons on hydraulics as well as the lectures of the famous physician and naturalist Antonio Vallisneri. He studied literature, philosophy, theology, architecture, acoustics and music theory. He made significant contributions in the field of physics and mathematics applied ...

Jean-Paul Marat
Jean-Paul Marat (, , ; born Jean-Paul Mara; 24 May 1743 – 13 July 1793) was a French political theorist, physician, and scientist. A journalist and politician during the French Revolution, he was a vigorous defender of the ''sans-culottes'', a radical voice, and published his views in pamphlets, placards and newspapers. His periodical ''L'Ami du peuple'' (''The Friend of the People'') made him an unofficial link with the radical Jacobin group that came to power after June 1793. His journalism was known for its fierce tone and uncompromising stance toward the new leaders and institutions of the revolution. Responsibility for the September massacres has been attributed to him, given his position of renown at the time, and a paper trail of decisions leading up to the massacres. Others posit that the collective mentality which made them possible resulted from circumstances and not from the will of any particular individual.#Lefebvre, Lefebvre, p. 236 Marat was assassinated by ...

Nottingham General Hospital
Nottingham General Hospital was a major hospital in Nottingham, England. It was founded in 1781 and closed in 1992. History The hospital was the result of a legacy from John Key, a wealthy banker, who had left money in his will for hospitals to be built in Nottingham and York. The site selected for the hospital in Nottingham was part of the area known as Nottingham Park, immediately to the north of Nottingham Castle and near the wharves: one half of the land was given by Thomas Pelham-Clinton, 3rd Duke of Newcastle for the purpose and the other half by the town corporation.Bittiner and Lowe, p. 8 The foundation stone for the first building, which had been designed by John Simpson, was laid on 12 February 1781 and the hospital opened with 44 beds in September 1782. John Wesley, the Theology, theologian, was an early visitor to the hospital.Bittiner and Lowe, p. 9 The hospital was extended with the Derbyshire wing, financed by a large donation from Henry Cavendish, which opened ...
