Rene Descartes, the French philosopher and mathematician who invented the Cartesian coordinate system, is considered the father of modern analytical geometry. His work was crucial to the discovery of infinitesimal calculus by Gottfried Liebniz and Isaac Newton.
Know MoreIn addition to his extraordinary contributions to mathematics, Descartes is probably best known to the general public for his famous philosophical proposition, "cogito ergo sum," meaning "I think, therefore I am." Much of Descartes philosophical work dealt with the question of how man can know whether he or anything else really exists. According to his famous argument, thinking about his own existence proves that he exists because there has to be someone there to do the thinking. This argument is so fundamental and familiar that philosophers often refer to it simply as "cogito."

Full Answer >Descartes' theory of knowledge is that it is a conviction based on reason that is so strong that no feeling of doubt can change it. Descartes' epistemology is largely described in terms of being the contrast of doubt, according to Stanford University.
Full Answer >Aristotle was responsible for major developments in many fields that are still studied today, including logic, zoology, science, astronomy and many more. Although many of his theories were eventually supplanted by more developed studies, his ideas were incredibly influential, and many of them still form the basis of modern thought.
Full Answer >According to Wichita State University, Rene Descartes invented the Cartesian Plane, which is a theory of using ordered pairs to determine a specific point. This theory, explained in "La Geometrie," led to the invention of analytical geometry in which algebra is applied to geometry.
