3.  French Mathematician and philosopher.
 Father of modern Philosophy.

Mathematical.

4.  Born March 31, 1596 at La Haye, France.
 Father Joachim
 Mother Jeanne Brochard Descartes

 He sought out famous Mathematicians,
Scientists and Philosophers where ever he

6.  Most significant friendship was with Issac
Beeckman (Dutch Mathematician) who

that our terminology Cartesian plane and
Cartesian coordinate system is derived from
his name!.....

10.  His major contribution lies in bringing fourth
coordinate system.
 Cartesian coordinate system tended to
explain the algebraic equation through
geometrical shapes.
 He invented the convention of representing
unknowns in equation by x, y and z.

11.  Meditation on First Philosophy.

 Compendium Musicae
 Discourse on the Method
