- Doubling the cube - Wikipedia
Doubling the cube, also known as the Delian problem, is an ancient [a][1]: 9 geometric problem Given the edge of a cube, the problem requires the construction of the edge of a second cube whose volume is double that of the first
- Descartes Systems Group - Wikipedia

- Cubic equation - Wikipedia
Cubic equations were known to the ancient Babylonians, Greeks, Chinese, Indians, and Egyptians [1][2][3] Babylonian (20th to 16th centuries BC) cuneiform tablets have been found with tables for calculating cubes and cube roots [4][5] The Babylonians could have used the tables to solve cubic equations, but no evidence exists to confirm that they did [6] The problem of doubling the cube
- Constructible number - Wikipedia
The square root of 2 is equal to the length of the hypotenuse of a right triangle with legs of length 1 and is therefore a constructible number In geometry and algebra, a real number is constructible if and only if, given a line segment of unit length, a line segment of length can be constructed with compass and straightedge in a finite number of steps Equivalently, is constructible if and
- Mind–body dualism - Wikipedia
This gave Descartes his first inkling that the mind and body were different things The mind, according to Descartes, was a "thinking thing" (Latin: res cogitans), and an immaterial substance This "thing" was the essence of himself, that which doubts, believes, hopes, and thinks
- Rational root theorem - Wikipedia
The general cubic equation with integer coefficients has three solutions in the complex plane If the rational root test finds no rational solutions, then the only way to express the solutions algebraically uses cube roots But if the test finds a rational solution r, then factoring out (x – r) leaves a quadratic polynomial whose two roots, found with the quadratic formula, are the remaining
- Folium of Descartes - Wikipedia
Folium of Descartes The folium of Descartes (green) with asymptote (blue), when In geometry, the folium of Descartes (from Latin folium ' leaf '; named for René Descartes) is an algebraic curve defined by the implicit equation
- Cartesian doubt - Wikipedia
Cartesian doubt is methodological It uses doubt as a route to certain knowledge by identifying what can't be doubted The fallibility of sense data in particular is a subject of Cartesian doubt There are several interpretations as to the objective of Descartes' skepticism Prominent among these is a foundationalist account, which claims that Descartes' skepticism aims to eliminate all belief
