The Fractal Geometry Of Nature Book Pdf



As technology has improved, mathematically accurate, computer-drawn fractals have become more detailed. Early drawings were low-resolution black and white; later drawings were higher 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.

Fractal geometry is a new way of looking at the world. This book combines text and graphics to offer the most accessible amount that any reader is likely to find, helping in the overall move toward scientific literacy.


This book has become a seminal text on the mathematics of Fractals. It introduces the general mathematical theory and applications of fractals in a way that is accessible to students from a wide range of disciplines.


This book offers both a theoretically unifying understanding of polynomial curves and surfaces and an effective approach to implementation. It is also an exellent introduction to geometry concepts used in computer graphics, vision, robotics, geometric modeling.

Nature is not naturally smooth edged. Smooth surfaces are an exception. Euclidean geometry, the geometry that we learned in high school, describes ideal shapes -- the sphere, the circle, the cube, the square. Euclidean shapes are man-made -- not nature made.


Fractal geometry is the geometry of irregular shapes that we find in nature. Fractal geometry gives us the power to describe natural shapes that are inexpressible using Euclidean geometry. One can easily observe fractal patterns in trees, rivers, mountains, and the structure of mammalian lungs. The term "fractal"was coined by Benoit Mandelbrot in 1975 and was derived from the Latin word "fractus" meaning "broken" or "fractured."


The key characteristics of fractals is that they are irregular and self similar. Self-similarity means that as the magnification of an object changes, the shape (the geometry) of the fractal does not change. The shape of a magnified portion of the object looks approximately the same as does the original portion. A fractal pattern looks the same close up as it does far away. When we look very closely at patterns that are created with Euclidean geometry, the shapes look more and more like simple straight lines, but that when you look at a fractal with greater magnification you see more and more detail.


Alveoli are the tiny pockets in your lungs that store air for brief periods to allow time for oxygen to absorbed into the blood-stream. In order to permit the absorption of sufficient oxygen into the blood stream, the alveoli must have a large total surface area. In fact, human lungs contain 300 million alveoli with a surface area of 160 square meters -- the size of a singles tennis court. The volume of a human lung contained in the chest cavity is only about 6 liters. So, this huge surface area is contained within this small volume. This can happen only because the geometry of the lung structure is fractal or self similar.


Fractal geometry is very suitable for modelling all sorts of natural phenomena because it provides a very good representation of aspects of real life. Fractal theory offers methods for describing the inherent irregularity of natural objects. Since many of nature's patterns are fractal, we will find it useful to build models with fractal features if we wish to gain a deeper understanding.


Like ice formations, other natural forms of crystals like those created from minerals can also exhibit Fractal properties. Depending on the specific formation of crystal and the minerals used some are more fractal in appearance than others. A great example of this would be the cubic nature of some formations of Amethyst or pyrite.


Benoit Mandelbrot, whose pioneering work on fractal geometry made him one of the few modern mathematicians to approach widespread fame, died October 14 at the age of 85. The cause, his wife told The New York Times, was pancreatic cancer.


In books such as The Fractal Geometry of Nature (1982) and The (Mis)behavior of Markets: A Fractal View of Risk, Ruin, and Reward (2004), Mandelbrot made the case that fractals could help make sense of everything from the shape of coastlines (pdf) to the performance of Wall Street. During a talk in New York City in 2009, he lamented that he was not a younger man with more time to learn new disciplines such as climate modeling.


How can we describe a fern as a precise mathematical shape? How can we build a mathematical model of this wonderful object? Enter a completely new world of beautiful shapes: a branch of mathematics known as fractal geometry.


Though the geometry of fractal shapes is infinitely complex, a third trait of fractals is that their complexity arises from very simple core definitions. The shape of a fractal can be completely captured by a small list of mathematical mappings that describe exactly how the smaller copies are arranged to form the whole fractal.


Similarly, your lungs are about 2.97 dimensional - their fractal geometry allows them to pack lots of surface area (a few tennis courts) into a small volume (a few tennis balls). Packing such a huge surface area into your body provides you with the ability to extract enough oxygen to keep you alive.


He called this family of shapes fractals, from the Latin adjective fractus, meaning fragmented or irregular. Such objects, Mandelbrot noted, are present in nature as well as in a wide range of fields.


Fractals are generally formed by a simple procedure, such as recursion. They tend to be self-similar (that is, they contain copies of themselves at different scales), with detail at every scale, and with an irregular structure that cannot readily be described in terms of traditional geometry. The Mathigon site has a good introductory guide to fractals.


The Ecological Thought is, by Morton's own admission, the "prequel" to Ecology without Nature. Although written accessibly to appeal to a more-than-ecocritical audience (the interested scholar can follow the trail of endnotes), there is no question that the book demands of its readers a ruthless reframing of ecological views. He begins with an argument familiar to readers of Ecology without Nature: that the modern era, even as it developed the possibility of ecological thought, has made that thought impossible to achieve because of our reliance on ideas of (external) nature, wilderness, and the like. The more we struggle to preserve Nature, the less we see what's really going on in the world of human encounter and connection with other beings. What we need is something entirely different: not just ecological thinking, but "the ecological thought," which is, as he writes, "the thinking of interconnectedness" itself, meaning both thinking about it and thinking from it. And the rest of the book spells out, employing an eclectic range of ideas and thinkers (Charles Darwin to Buddhism, Blade Runner [1982] to William Blake), what that thinking means, why it's a better view of nature than Nature, and what the consequences might be of the radical openness that he understands as integral to this ecological thought.
