En nuestro trabajo comparamos, por un lado, la perspectiva de Peirce con críticas contemporáneas de la lógica y, por otro, consideramos el estudio de dos casos históricos significativos: la resolución platónica del problema de la duplicación del cuadrado (Menón 81c-85d), y el método de transmutación de curvas que Leibniz propone en De.

Sçavoir – La Résolution de tous les Problèmes touchant la Roulette qu’il avoit proposez publiquement au mois de Juin 1658. Lettres de A Dettonville contenant Quelques-unes de ses Inventions de Géométrie. As is well known, upon publication of his Vera circuli et hyperbolae quadratura (Padua 1667), James Gregory became involved in a bitter controversy with Christiaan Huygens over the truth of one of his major propositions. In July 1674 he was elected as the first exclusively Mathematics professor at Edinburgh University, and earlier that year the first Gregorian telescope - the type of instrument that would be used universally throughout the eighteenth century - was presented to the Royal Society in February 1674. coincides with the publication of James Gregorys Vera Circuli et Hyperbolae Quadratura. attempt to show that and e are transcendental (not. 106 3.5.2 Mercators and Walliss Quadrature of the Hyperbola. Towards the end of his life he was also absorbed with the theory of equations. 1667: Vera circuli et hyperbolae quadratura (True quadrature of the circle and hyperbola). In 1667 James Gregory issued his Vera Circuli et Hyperbolae Quadratura, in which he showed how the areas of the circle and hyperbola can be computed using.
In 1672-73 he communicated with Isaac Newton (1642-1727) on the merits or otherwise of their own telescopes. James Gregory attempted a proof of its impossibility in Vera Circuli et Hyperbolae Quadratura (The True Squaring of the Circle and of the Hyperbola) in 1667. Also in 1668 he was appointed Professor of Mathematics at St. The same year he published his Exercitationes geometricae.

Between 16, Gregory studied mathematics in Padua, Italy, and while there he published Vera circuli et hyperbolae quadratura (1667) in which he showed how to find the areas of the circle, ellipse, and hyperbola.Īfter his return to Britain, he was elected a Fellow of the Royal Society in June 1668. His scientific talent was encouraged by his inventor brother, David Gregory (1627-1720) and at the age of twenty-four he published Optica promota (1663) which was a description of a reflecting telescope which he had invented in 1661. De quadratura arithmetica circuli ellipseos et hyperbolae cujus corollarium est trigonometria sine tabulis: Primeira menção de responsabilidade: Gottfried Wilhelm Leibniz: 215 - Descrição Física Outras indicações físicas: il: Indicação específica do tipo de material e extensão do item: 160 p: 210 - Publicação. He was educated in Aberdeen and then studied at Marischal College in the city. The mathematician James Gregory was born at the Manse of Drumoak, Aberdeenshire, in November 1638. Before he left Padua, Gregory published Vera Circuli et Hyperbolae Quadratura (1667) in which he approximated the areas of the circle and hyperbola with. As is well known, upon publication of his Vera circuli et hyperbolae quadratura (Padua 1667), James Gregory became involved in a bitter controversy with.
