The same fractal as above, magnified 2000-fold, where the Mandelbrot set fine detail resembles the detail at low magnification. In mathematics, a fractal is a subset of a Euclidean space for which the strictly exceeds the. Fractals tend to appear nearly the same at different levels, as is illustrated here in the successively small magnifications of the; Because of this, fractals are encountered ubiquitously in nature. Fractals exhibit similar patterns at increasingly small scales called self similarity, also known as expanding symmetry or unfolding symmetry; If this replication is exactly the same at every scale, as in the, it is called affine self-similar. One way that fractals are different from finite is the way in which they. Doubling the edge lengths of a multiplies its area by four, which is two (the ratio of the new to the old side length) raised to the power of two (the dimension of the space the polygon resides in).

Many of the proofs are accompanied by interactive Java illustrations. My first math droodle was also related to the Pythagorean theorem. Cracked Domino - a proof by Mario Pacek (aka Pakoslaw Gwizdalski) - also requires some thought.

Likewise, if the radius of a sphere is doubled, its scales by eight, which is two (the ratio of the new to the old radius) to the power of three (the dimension that the sphere resides in). However, if a fractal's one-dimensional lengths are all doubled, the spatial content of the fractal scales by a power that is not necessarily an. This power is called the of the fractal, and it usually exceeds the fractal's. Analytically, fractals are usually nowhere. An infinite fractal curve can be conceived of as winding through space differently from an ordinary line – although it is still, its fractal dimension indicates that it also resembles a surface.

(to level 6), a fractal with a of 1 and a of 1.893 Starting in the 17th century with notions of, fractals have moved through increasingly rigorous mathematical treatment of the concept to the study of but not functions in the 19th century by the seminal work of,, and, and on to the coining of the word in the 20th century with a subsequent burgeoning of interest in fractals and computer-based modelling in the 20th century. The term 'fractal' was first used by mathematician in 1975. Mandelbrot based it on the Latin, meaning 'broken' or 'fractured', and used it to extend the concept of theoretical fractional to geometric. There is some disagreement among mathematicians about how the concept of a fractal should be formally defined. Mandelbrot himself summarized it as 'beautiful, damn hard, increasingly useful.

That's fractals.' More formally, in 1982 Mandelbrot stated that 'A fractal is by definition a set for which the strictly exceeds the.' Later, seeing this as too restrictive, he simplified and expanded the definition to: 'A fractal is a shape made of parts similar to the whole in some way.' Still later, Mandelbrot settled on this use of the language: '.to use fractal without a pedantic definition, to use as a generic term applicable to all the variants'. The consensus is that theoretical fractals are infinitely self-similar,, and detailed mathematical constructs having fractal dimensions, of which many have been formulated and studied in great depth. Fractals are not limited to geometric patterns, but can also describe processes in time.
