René Descartes (/ d eɪ ˈ k ɑːr t / or UK: / ˈ d eɪ k ɑːr t /; French: [ʁəne dekaʁt] (); Latinized: Renatus Cartesius; 31 March 1596 – 11 February 1650: 58 ) was a French philosopher, mathematician, and scientist who invented analytic geometry, linking the previously separate fields of geometry and algebra.

A Cartesian coordinate system (UK: / k ɑː ˈ t iː zj ə n /, US: / k ɑːr ˈ t i ʒ ə n /) in a plane is a coordinate system that specifies each point uniquely by a pair of numerical coordinates, which are the signed distances to the point from two fixed perpendicular oriented lines, measured in the same unit of length.

In number theory, a Descartes number is an odd number which would have been an odd perfect number, if one of its composite factors were prime.They are named after René Descartes who observed that the number D = 3 2 ⋅7 2 ⋅11 2 ⋅13 2 ⋅22021 = (3⋅1001) 2 ⋅ (22⋅1001 − 1) = 198585576189 would be an odd perfect number if only 22021 were a prime number, since the sum-of-divisors ...

Two-dimensional space (also known as 2D space, 2-space, or bi-dimensional space) is a geometric setting in which two values (called parameters) are required to determine the position of an element (i.e., point ). The set. R 2 {\displaystyle \mathbb {R} ^ {2}}

The image on the left is a cube viewed face-on. The analogous viewpoint of the tesseract in 4 dimensions is the cell-first perspective projection, shown on the right. One may draw an analogy between the two: just as the cube projects to a square, the tesseract projects to a cube. Note that the other 5 faces of the cube are not seen here.
