Author: Since T. Pappas from "mathematical anecdote Collection", Shanghai Education Publishing House centuries, people always use objects and concepts Euclidean geometry (such as point, line, plane, space, square, round ...) To describe our survival world. Non-Europe Geometric discovery introduced new objects drawing the phenomenon of the universe. Fractal is such an object. The fractal thinking is in the work of mathematically from 1875 to 1925. These objects are labeled with deformity monsters, and people are convinced that it has no scientific value. It is a well-known fractal today. The word is created by Mandelo in 1975, and Mandelo has a wide discovery in this field. In terms of strict sense, the fractal is an object, and after the fine part is enlarged, its structure is still the same as the original. This is a distinct contrast with a circular shape, and it becomes more straight after zooming in the circle. Fractal can be divided into two categories: one is geometric fractal, it continues to repeat the same pattern pattern; the other is random fracture. Computers and computer drawings can reliably bring these "malformed monsters" back to their lives, almost fracture immediately on the computer, and show their wonderful shape, art pattern or subtle landscape. Some people may feel that only the formal shape of the European miles can be applied in science, but the above new form provides us with awareness of nature from different perspective perspectives. Fractal is a new mathematics field - sometimes returning it into nature, because these singular and chaotic shapes not only depict natural phenomena such as earthquake, tree, branches, ginger roots, coastlines, but also in astronomy, economy , Weather, movie production, etc. also have widespread applications
