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.
Know MorePart of the Cartesian Plane theory is the Cartesian coordinate system, a three-dimensional coordinate system. The modern Cartesian coordinate system is often simplified to a two-dimensional system with a horizontal line called the x-axis and a vertical line called the y-axis. The lines are labelled and intersect at the origin point at zero. The location of points between the x- and y-axes are determined by reading the numbers on both axes.
Rene Descartes lived during the 1600s. He started his education at the age of eight, in the Jesuit College in France. Despite frequent ill health, Descartes studied at the college for eight years before moving to Paris to study mathematics. He thought that mathematics was the portal to understanding the science of nature. At the age of 21, in 1617, he joined the army. It was during his military service that he truly started his love affair with mathematics. He left the army in 1621 to devote his time to mathematics, but it took him 17 years to publish "La Geometrie."

Some were published posthumously as were some essays and letters that were lesser known.
Full Answer >French philosopher and mathematician Rene Descartes is behind many important concepts, from the Cartesian plane in mathematics to the "I think, therefore I am" philosophy. Descartes was born to humble beginnings, but he managed to become an important thinker and notable person.
Full Answer >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.
Full Answer >Rene Descartes, widely regarded as the father of modern philosophy, broke with the Aristotelian tradition, helping establish modern rationalism. He argued for a mechanistic universe in opposition to Aristotle's views on causality. He also made important contributions to mathematics and physics.
