Science Quotes by Benoit Mandelbrot (12 quotes)
Natura non facit saltum or, Nature does not make leaps
If you assume continuity, you can open the wellstocked mathematical toolkit of continuous functions and differential equations, the saws and hammers of engineering and physics for the past two centuries (and the foreseeable future).
— Benoit Mandelbrot
A fractal is a mathematical set or concrete object that is irregular or fragmented at all scales.
— Benoit Mandelbrot
Being a language, mathematics may be used not only to inform but also, among other things, to seduce.
— Benoit Mandelbrot
For most of my life, one of the persons most baffled by my own work was myself.
— Benoit Mandelbrot
I claim that many patterns of Nature are so irregular and fragmented, that, compared with Euclida term used in this work to denote all of standard geometryNature exhibits not simply a higher degree but an altogether different level of complexity
The existence of these patterns challenges us to study these forms that Euclid leaves aside as being formless, to investigate the morphology of the amorphous.
— Benoit Mandelbrot
I conceived and developed a new geometry of nature and implemented its use in a number of diverse fields. It describes many of the irregular and fragmented patterns around us, and leads to fullfledged theories, by identifying a family of shapes I call fractals.
— Benoit Mandelbrot
Round about the accredited and orderly facts of every science there ever floats a sort of dustcloud of exceptional observations, of occurrences minute and irregular and seldom met with, which it always proves more easy to ignore than to attend to.
— Benoit Mandelbrot
Science would be ruined if (like sports) it were to put competition above everything else, and if it were to clarify the rules of competition by withdrawing entirely into narrowly defined specialties. The rare scholars who are nomadsbychoice are essential to the intellectual welfare of the settled disciplines.
— Benoit Mandelbrot
The existence of these patterns [fractals] challenges us to study forms that Euclid leaves aside as being formless, to investigate the morphology of the amorphous. Mathematicians have disdained this challenge, however, and have increasingly chosen to flee from nature by devising theories unrelated to anything we can see or feel.
— Benoit Mandelbrot
The most complex object in mathematics, the Mandelbrot Set
is so complex as to be uncontrollable by mankind and describable as chaos.
— Benoit Mandelbrot
The theory of probability is the only mathematical tool available to help map the unknown and the uncontrollable. It is fortunate that this tool, while tricky, is extraordinarily powerful and convenient.
— Benoit Mandelbrot
Why is geometry often described as cold and dry? One reason lies in its inability to describe the shape of a cloud, a mountain, a coastline, or a tree. Clouds are not spheres, mountains are not cones, coastlines are not circles, and bark is not smooth, nor does lightning travel in a straight line
Nature exhibits not simply a higher degree but an altogether different level of complexity.
— Benoit Mandelbrot
Quotes by others about Benoit Mandelbrot (1)
Fractal is a word invented by Mandelbrot to bring together under one heading a large class of objects that have [played] ... an historical role ... in the development of pure mathematics. A great revolution of ideas separates the classical mathematics of the 19th century from the modern mathematics of the 20th. Classical mathematics had its roots in the regular geometric structures of Euclid and the continuously evolving dynamics of Newton.? Modern mathematics began with Cantor's set theory and Peano's spacefilling curve. Historically, the revolution was forced by the discovery of mathematical structures that did not fit the patterns of Euclid and Newton. These new structures were regarded ... as 'pathological,' ... as a 'gallery of monsters,' akin to the cubist paintings and atonal music that were upsetting established standards of taste in the arts at about the same time. The mathematicians who created the monsters regarded them as important in showing that the world of pure mathematics contains a richness of possibilities going far beyond the simple structures that they saw in Nature. Twentiethcentury mathematics flowered in the belief that it had transcended completely the limitations imposed by its natural origins.
Now, as Mandelbrot points out, ... Nature has played a joke on the mathematicians. The 19thcentury mathematicians may not have been lacking in imagination, but Nature was not. The same pathological structures that the mathematicians invented to break loose from 19thcentury naturalism turn out to be inherent in familiar objects all around us.
