Antoine Cavalleri
Antoine Cavalleri (1698–1765) was a Jesuit professor of mathematics at Cahors during much of the French Enlightenment in the 18th century, until late in the reign of Louis XV of France. Intellectual climate of the age During the early years of the 18th century Isaac Newton's work on gravity was still incompletely accepted in France and Descartes' vortex theory had not yet been conclusively superseded. One result was the difficulty of formulating and establishing a coherent and compelling explanatory theory of tidal action. The French ''Académie Royale des Sciences'' both supported practical research into tidal effects, and offered a prize for the best essay to establish the topic on a sound mathematical and theoretical footing. Three essays were selected for prizes, all of them by supporters of Newtonian theory. They were Daniel Bernoulli, Leonhard Euler, and Colin Maclaurin. However, it was rumoured by Pierre Louis Maupertuis that the reason that Cavalleri was added to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cahors
Cahors (; ) is a Communes of France, commune in the western part of Southern France. It is the smallest prefecture among the 13 departments that constitute the Occitania (administrative region), Occitanie Region. The capital and main city of the Lot (department), Lot department and the historical center of the Quercy, Cahors is home to 20,141 ''cadurciennes'' and ''cadurciens'' (2021). Nestled in a Meander cutoff, meander of the Lot (river), Lot and surrounded by steep arid limestone hills, this historic city is home to a great monumental diversity, mainly inherited from Ancient Rome, Roman times and the Middle Ages; the city's monuments include a historic city centre, Cahors Cathedral, Saint-Étienne cathedral, Roman walls and the famous Pont Valentré, Valentré bridge (a UNESCO World Heritage Site as part of the pilgrimage path to Santiago de Compostela). Famed for its Cahors wine, wine and gastronomy (truffles and foie gras), this southern French city holds the label of the ...

Jean Le Rond D'Alembert
Jean-Baptiste le Rond d'Alembert ( ; ; 16 November 1717 – 29 October 1783) was a French mathematician, mechanician, physicist, philosopher, and music theorist. Until 1759 he was, together with Denis Diderot, a co-editor of the ''Encyclopédie''. D'Alembert's formula for obtaining solutions to the wave equation is named after him. The wave equation is sometimes referred to as d'Alembert's equation, and the fundamental theorem of algebra is named after d'Alembert in French. Early years Born in Paris, d'Alembert was the natural son of the writer Claudine Guérin de Tencin and the chevalier Louis-Camus Destouches, an artillery officer. Destouches was abroad at the time of d'Alembert's birth. Days after birth his mother left him on the steps of the church. According to custom, he was named after the patron saint of the church. D'Alembert was placed in an orphanage for foundling children, but his father found him and placed him with the wife of a glazier, Madame Rousseau ...

18th-century French Jesuits
The 18th century lasted from 1 January 1701 (represented by the Roman numerals MDCCI) to 31 December 1800 (MDCCC). During the 18th century, elements of Enlightenment thinking culminated in the Atlantic Revolutions. Revolutions began to challenge the legitimacy of monarchical and aristocratic power structures. The Industrial Revolution began mid-century, leading to radical changes in human society and the environment. The European colonization of the Americas and other parts of the world intensified and associated mass migrations of people grew in size as part of the Age of Sail. During the century, slave trading expanded across the shores of the Atlantic Ocean, while declining in Russia and China. Western historians have occasionally defined the 18th century otherwise for the purposes of their work. For example, the "short" 18th century may be defined as 1715–1789, denoting the period of time between the death of Louis XIV of France and the start of the French Revolutio ...

Philosophiæ Naturalis Principia Mathematica
(English: ''The Mathematical Principles of Natural Philosophy''), often referred to as simply the (), is a book by Isaac Newton that expounds Newton's laws of motion and his law of universal gravitation. The ''Principia'' is written in Latin and comprises three volumes, and was authorized, imprimatur, by Samuel Pepys, then-President of the Royal Society on 5 July 1686 and first published in 1687. The is considered one of the most important works in the history of science. The French mathematical physicist Alexis Clairaut assessed it in 1747: "The famous book of ''Mathematical Principles of Natural Philosophy'' marked the epoch of a great revolution in physics. The method followed by its illustrious author Sir Newton ... spread the light of mathematics on a science which up to then had remained in the darkness of conjectures and hypotheses." The French scientist Joseph-Louis Lagrange described it as "the greatest production of the human mind". French polymath Pierre-Simon ...

Action At A Distance
Action at a distance is the concept in physics that an object's motion (physics), motion can be affected by another object without the two being in Contact mechanics, physical contact; that is, it is the concept of the non-local interaction of objects that are separated in space. Coulomb's law and Newton's law of universal gravitation are based on action at a distance. Historically, action at a distance was the earliest scientific model for gravity and electricity and it continues to be useful in many practical cases. In the 19th and 20th centuries, field models arose to explain these phenomena with more precision. The discovery of Electron, electrons and of special relativity led to new action at a distance models providing alternative to field theories. Under our modern understanding, the four fundamental interactions (gravity, electromagnetism, the strong interaction and the weak interaction) in all of physics are not described by action at a distance. Categories of action I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Age Of Enlightenment
The Age of Enlightenment (also the Age of Reason and the Enlightenment) was a Europe, European Intellect, intellectual and Philosophy, philosophical movement active from the late 17th to early 19th century. Chiefly valuing knowledge gained through rationalism and empiricism, the Enlightenment was concerned with a wide range of social and Politics, political ideals such as natural law, liberty, and progress, toleration and fraternity (philosophy), fraternity, constitutional government, and the formal separation of church and state. The Enlightenment was preceded by and overlapped the Scientific Revolution, which included the work of Johannes Kepler, Galileo Galilei, Francis Bacon, Pierre Gassendi, Christiaan Huygens and Isaac Newton, among others, as well as the philosophy of Descartes, Hobbes, Spinoza, Leibniz, and John Locke. The dating of the period of the beginning of the Enlightenment can be attributed to the publication of René Descartes' ''Discourse on the Method'' in 1 ...

René Antoine Ferchault De Réaumur
René Antoine Ferchault de Réaumur (; ; 28 February 1683 – 17 October 1757) was a French entomologist and writer who contributed to many different fields, especially the study of insects. He introduced the Réaumur temperature scale. Life Réaumur was born in a prominent La Rochelle family and educated in Paris. He learned philosophy in the Jesuits' college at Poitiers, and in 1699 went to Bourges to study civil law and mathematics under the charge of an uncle, canon of La Sainte-Chapelle. In 1703 he went to Paris, where he continued the study of mathematics and physics. In 1708, at the age of 24, he was nominated by Pierre Varignon (who taught him mathematics) and elected a member of the Académie des Sciences.Egerton, F.
