Kartézia

Kartézia is a term primarily used in philosophy and mathematics. In philosophy, it is often associated with René Descartes, a French philosopher, mathematician, and scientist. His work explored the nature of reality, knowledge, and the mind-body problem. The concept of "kartézia" can refer to Cartesian doubt, a method of systematic skepticism where one doubts everything that can be doubted in order to find indubitable truths. It can also refer to Cartesian dualism, the philosophical position that mind and body are distinct substances.

In mathematics, "kartézia" is a reference to the Cartesian coordinate system, developed by Descartes. This system uses two perpendicular axes, the x-axis and the y-axis, to define any point in a plane by a pair of numbers called coordinates. This invention revolutionized geometry and algebra by allowing them to be merged, a field now known as analytic geometry. The Cartesian coordinate system is fundamental to many areas of mathematics and its applications in science and engineering. The term "kartézia" thus encapsulates both a philosophical approach and a foundational mathematical tool.
