Foundations of geometry different sets of axioms for Euclidean geometry, any of these can replace the Euclidean parallel postulate. The following partial list indicates some of these theorems that are of historical interest. Absolute geometry is a geometry based on an axiom system consisting of all the axioms giving Euclidean geometry except for the parallel postulate or any of its alternatives. The term was introduced by János Bolyai in 1832. It is sometimes referred to as neutral geometry, as it is neutral with respect to the parallel postulate. In Euclid's "Elements", the first 28 propositions and Proposition I.31 avoid using the parallel postulate,
The Fractal Geometry of Nature resolution and in color. Many examples were created by programmers working with Mandelbrot, primarily at IBM Research. These visualizations have added to persuasiveness of the books and their impact on the scientific community. The Fractal Geometry of Nature The Fractal Geometry of Nature is a 1982 book by the Franco-American mathematician Benoît Mandelbrot. "The Fractal Geometry of Nature" is a revised and enlarged version of his 1977 book entitled "Fractals: Form, Chance and Dimension", which in turn was a revised, enlarged, and translated version of his 1975 French book, "Les Objects Fractals: Forme, Hasard et Dimension". "American Scientist" put the
