character brief introduction

René Descartes, born in Toulouse, France, and died in Stockholm, Sweden on 11 February 1650, was a famous French philosopher, mathematician and physicist who made an important contribution to the development of modern mathematics and is considered the father of geometric analysis by formalizing the geometric coordinate system. He was a representative of the idealistic dualism, leaving the name ¡°I think I am¡± (or translated as ¡°thinking is the only certain existence¡±), put forward the claim of ¡°universal suspicion¡± and was the founder of Western modern philosophy thought. His philosophical thought deeply influenced the subsequent generations of Europeans, developing the philosophy of so-called ¡°European rationalism¡±. Hegel called him ¡°the father of modern philosophy

Main achievements

In the field of mathematics, Descartes founded the analysis of geometry, the problem of geometry into generations, and proposed the unification of geometry as graphics. In the field of physics, Descartes first clearly proposed the law of motion conservation: the total amount of matter and movement remained unchanged forever. In the field of astronomy, he first relied on mechanics rather than theology, explaining the process of formation of the sky, the sun, planets, satellites, comets, etc. In the field of physiology, Descartes proposed stimulation responses, making a certain contribution to physiology.

The core of Deacal's thought was to reduce the problems of geometry to the problems of algebraic forms, calculate and prove them using the methods of generic mathematics, thus achieving the ultimate goal of solving the problems of geometry. In 1637, Deacal published The Geometry, which founded the line of rectangular coordinates.

The Methodology, published in 1637, was his earliest work, accompanied by three short articles: (1) The Optical Optics, (2) The Meteorology, (3) The Geometry. In which, in the Appendix (3), he very thoroughly described the analysis of the theory of geometry. The establishment of the analysis of the theory of geometry was the greatest achievement of Deacal for world mathematics, as Engels assessed, from which the movement entered mathematics, dialectics entered mathematics, and mathematics from constant mathematics to the new era of variable mathematics.
