Descartes, (1596- 1650), a French village physicist, was one of the founders of analytic geometry. He believes that mathematics is the theory and model of all other sciences, and puts forward a theory based on mathematics and centered on deduction, which is a philosophy left to future generations. The development of mathematics and natural science has played a great role.

Descartes analyzed the advantages and disadvantages of geometry and algebra, and showed that he wanted to find a method that included the advantages of these two sciences without their disadvantages. This method is to study the geometric problem-analytic geometry by algebraic method. Geometry confirmed Descartes' position in the history of mathematics. Geometry put forward the main ideas and methods of analytic geometry, which marked the birth of analytic geometry and was called the turning point of mathematics by Sigmund. Later, mankind entered the stage of variable mathematics.

Descartes also improved the Vedic symbols. He used a, b, c to represent the known number, and x, y, z to represent the unknown number, creating? =? , and other symbols, continue to this day.

Descartes also has many unique features in physics, physiology and astronomy.
