    In mathematics, a fractal is a self-similar subset of Euclidean space whose fractal dimension strictly exceeds its topological ls appear the same at different levels, as illustrated in successive magnifications of the Mandelbrot set; because of this, fractals are encountered ubiquitously in nature. Fractals exhibit similar patterns at increasingly small scales called self. Fractal definition is - any of various extremely irregular curves or shapes for which any suitably chosen part is similar in shape to a given larger or smaller part when magnified or reduced to .
