The story

The Spiral lies in the same valley, deeper still, at 1,400 steps per point. The closer a point is to the edge of the set, the slower it escapes, so the program has to compute for longer. Snail shells and young fern fronds unrolling make a similar curl.

MATHEMATICS

The maths behind the picture

Every piece is computed, not drawn. These are the real equations and numbers from the program that made this exact piece.

Equations

zₙ₊₁ = zₙ² + cz₀ = 0|zₙ| > 2  ⇒  c ∉ M

Parameters

Re(c) centre: -0.761629
Im(c) centre: -0.084758
Window width: 0.0035
Magnification ×: 885.7
Max iterations: 1,400
Rotation: -15.1°

Measured while drawing

Points computed: 1,533,070
Inside the set (%): 2.22
Mean escape: 147.6

What these numbers mean

This window is magnified 886 times. 2.2% of points stay trapped in the set forever; the rest escape after 148 steps on average. Each point's colour is exactly that step count.

HISTORY

Where this idea comes from

1918
Gaston Julia and Pierre Fatou study the iteration of complex functions, with no computers, only pencil and paper.
1978
Robert Brooks and Peter Matelski publish the first picture of the set, printed in characters on a line printer.
1980
Benoit Mandelbrot at IBM explores the set by computer and reveals its infinite complexity. He had coined the word "fractal" in 1975.
1982
Adrien Douady and John Hubbard prove the set is connected and name it after Mandelbrot.

In nature

Ferns, romanesco cauliflower and a sea coast share the property of the set's edge: the part looks like the whole. In 1967 Mandelbrot asked how long the coast of Britain is. The answer depends on how finely you measure.
