[en] We will address the experimental method in the seventeenth century, based on the scientific-experimental method of Galileo and Newton. We are interested in how Descartes and Leibniz especially collect the ideas of Galileo and Newton when building their methods of scientific experimentation in the s. xvii. Of all modern, Ren? Descartes was the philosopher came to the right to turn the stolen knob from Aristotle, as was universally read and had many followers. Descartes created a metaphysical foundation, an epistemology and an integral system of nature that covering the explanation of all phenomena. He promised a foolproof method of discovery. His reputation grew through the work of skilled and patients exhibitors, especially Jacques Rohault (1620-1673), and when began to be noticeable the defects of his own explanations of natural phenomena, his system was revitalized by the writings of ?newcartesians? extremely competents, among the cases of Huygens, Malebranche and Leibniz himself. De facto, despite the contrary powerful influence of Newton, Descartes throw light would extend to penetrate the more general glow of the Enlightenment of the eighteenth century and its main monument, the Encyclopedy of Diderot and d?Alembert. On the other hand, Descartes was a brilliant pure mathematician who also did work lasting value in the field of mathematical physics; if he was not been philosopher, also occupy a prominent place in the history of science. In all aspects except one, the experimental systematic research, Descartes excelled at the time of his death, and after this he would be, for all the people were able to understand his books, the great luminary, the man who had opened a wide path for the posterity.

[es] Vamos a abordar el m?todo experimental en el siglo xvii, bas?ndonos en el m?todo cient?fico-experimental de Galileo y Newton. Nos interesa conocer c?mo recogen Descartes y sobre todo Leibniz las ideas de Galileo y Newton a la hora de construir sus m?todos de experimentaci?n cient?fica en el s. xvii. De entre todos los modernos, Ren? Descartes fue el que m?s se acerc? al derecho de llevar el mando robado de Arist?teles, puesto que se le le?a universalmente y ten?a numerosos seguidores. Descartes cre? un fundamento metaf?sico, una epistemolog?a y un sistema ?ntegro de la naturaleza que abarcaba la explicaci?n de todos los fen?menos. Prometi? un m?todo infalible de descubrimiento. Su reputaci?n aument? gracias a la labor de h?biles y pacientes expositores, en especial de Jacques Rohault (1620-1673), y cuando empezaron a hacerse notorios los defectos de sus propias explicaciones de los fen?menos naturales, su sistema cobr? nueva vida gracias a los escritos de ?neocartesianos? extremadamente competentes, entre los que destacan Huygens, Malebranche y el propio Leibniz. De facto, a pesar de la poderosa influencia contraria de Newton, la luz que arrojara Descartes se extender?a hasta penetrar en el resplandor m?s general de la Ilustraci?n del siglo xviii y de su principal monumento, la Enciclopedia de Diderot y d?Alembert. Por otro lado, Descartes era un matem?tico puro genial que tambi?n hizo trabajos de valor imperecedero en el campo de la f?sica matem?tica; de no haber sido fil?sofo, igualmente ocupar?a un lugar prominente en la historia de la ciencia. En todos los aspectos menos en uno, la investigaci?n experimental sistem?tica, Descartes sobresal?a en el momento de su muerte, y despu?s de ?sta ser?a, para todos quienes en aquel momento eran capaces de comprender sus libros, la gran luminaria, el hombre que hab?a abierto un camino ancho para la posteridad.
