Institute of Life Long Learning Mathematical Awareness A Concurrent Course For B.A. (Hons) FRACTALS IN NATURE _____________________________________________________________________ What is a Fractal Suppose, one needs to measure the coastline of India. It can be measured with mile-long rulers and get a certain measurement. What if the rulers are replaced with foot-long rulers? Which measurement would give you a larger measurement. are further replaced with an inch-long ruler? You could really get into the teeniest and coastline? You could measure it with shorter and shorter rulers, and the
The question of measuring a coastline was first raised in 1967 by Benoit Mandelbrot, the Polish-born French mathematician. There are numerous examples in nature where the repetitive behaviour of the curve (as in the coastline) could be seen. For instance, see below the picture of a broccoli : If you look a small part of the broccoli, you would notice that the shape is similar (if not identical) to the whole of it. This is also an example of a fractal. Such
