= Biography = //Born in La Haye en Touraine in March,31 ,1596 and died February 11th, 1650 in Stockholm, Sweden at age 53. He spent most of his adulthood in the new Dutch Republic and// studied mathematics, physiology and was a French Philosopher. Was very key in scientific revolution. A proponent of the 17th century of superstitions. " ﻿ Descartes proposed a mechanistic theory of the universe, the aim of which was to show that the world could be mapped out without allusion to subjective experience. His mechanistic approach was extended to the issue of animal consciousness. Mind, for Descartes, was a thing apart from the physical universe, a separate substance, linking human beings to the mind of God. The non-human, on the other hand, are nothing but complex automata, with no souls, minds, or reason. They can see, hear, and touch, but they are not, in any sense, conscious, and are unable to suffer or even to feel pain" Did not have a very good child hood his mother died when he was at the age of 1. Rene went to college at University of Poitiers and earned a Baccalaureate in 1616. Joined International college of war in the Dutch Republic at this time because the Dutch was at war. He was present at the Battle of White Mountian was a war that took place on November 8, 1620.

=Important mathematical discoveries = Rene founded analytic geometry and helped found Scientific Revolution. Analytic Geometry also known as "Coordinate Geometry" is the study of geomety, it inculdes alot of the same things we use in Algebra. Like "equations, terms and polynomials" and that leads us back to Geometry. Usually The "Coordinate Geometry" is used for equations and planes (two dementional surface) also for straight lines and squares. Most construction people use this for there blueprints. The coordinates for this is the simple (x,y) for two dementional, for three dementional you would use (x,y,z) [other options to]. This also includes "Distance and Angle" the formula for that is =﻿Work Outside of Mathematics = Rene was a French philosopher and a Physicist. Rene Descartes was concerned with the uncertainty in the sciences and the scepticism caused from the publications of "Sextus Empiricus", he rejected anything which seemed un certain and decided to only accept "apodeictic" knowledge as the truth. Descartes discovered at least one thing could be known apodictically. If he was doubting, then he had to exist. "Cogito Ergo Sum" - I think, therefore i am - became the first principle of "Cartesianism."

= Fun Facts = The Cartesian coordinate system was named after Rene Descartes . Rene said a quote "its all fun and games until somebody gets there eye poked out". In 1647, when he met Pascal and argued with him that a vacuum could not exist, and then again in 1648. In 1930 he changed his name to "Poitevin" to enroll in another college to study mathematics. Daughter named Francie. Descartes Qouted "And so something which I thought I was seeing with my eyes is in fact grasped solely by the faculty of judgment which is in my mind".
