The Mandlebrot set is a famous fractal with self-similarity over many levels of magnification. It was first plotted by Benoît Mandlebrot, who saw connections between fractals and real-world phenomena. Hobbyists have spent thousands of hours locating unique structures within the set.
A Mandlebrot set is a fractal that can be plotted using an iterative complex function. A fractal is a mathematically generated image that is rough, irregular and complex. A fractal also possesses self-similarity over many levels of magnification, so that tiny parts of the fractal look like larger parts. Fractals continue to appear complex no matter how much you zoom into them, leading some to say they have infinite complexity. The Mandlebrot set is the most famous example of a fractal, consisting of a cardoid, a circular object with a dimple on one side, surrounded by progressively smaller arrangements of neighboring circles and interesting spiral patterns, all tangent to each other. ‘other.
The mathematics behind the Mandlebrot set was devised in 1905 by Pierre Fatou, a French mathematician exploring the field of complex analytic dynamics. He liked to study the behavior of recursive processes, functions whose outputs were fed back into their inputs. Fatou attempted to manually plot some of the complex sets of him, but too many calculations were required to display the full picture of some of the sets (including the Mandlebrot set). It wasn’t until the distribution of desktop computers that this set’s texture became practical.
The Mandlebrot set was first plotted by Professor Benoît Mandlebrot, a mathematician who coined the term fractal and popularized the idea in a 1975 book called Fractal Objects: Form, Chance and Dimension. Before being called fractals, these structures were called “monstrous curves”.
Mandlebrot saw the connections between fractals such as his Mandlebrot set and real-world phenomena, prompting him to study the connections in detail. Fractal-like structures can be found in nature, for example in the arrangement of the petals on some flowers. Mandlebrot pointed out that real forms in nature never have the bland regularity of Euclidean geometric structures, but actually more closely resemble fractals. Other examples include shapes found in coasts and rivers, plants, blood vessels and lungs, galaxy clusters, Brownian motion, and patterns in the stock market.
Because the Mandlebrot set is so complex and exhibits such variation, hobbyists have spent thousands of hours locating unique structures within the set, color-coding them, and sharing them with others. Structures similar in appearance to the whole ensemble can be found on the smaller scales, sometimes connected to the main ensemble only by tiny tendrils. The apparent complexity of the set actually increases with magnification. Good software applications are available today for hobbyists to plot the Mandlebrot set and other fractals and to study their appearance.
