##### Welcome to our beginners guide to fractals!

One of the most basic fractal patterns is the typical branching – the rule for this is as simple as it gets:

*Split a line into 2 smaller lines.*

Repeat.

simple fractal branching

Each branch splits into two smaller ones

Curled fractal branching

If you add some random curves the static tree becomes much more realistic.

Mandelbrot-Set

Branching in the best known fractal

3d-branching

The same basic branching can produce beautiful 3d-trees

Do the shapes you just watched look familiar?

Of course they do – once you know what to look for, nature appears to be full of them:

Fractal forests

Fractal Branching is most obvious in trees

Elderflower

But also in many flowers..

Dry earth

When earth dries, it cracks in fractal branching patterns. This happens on many scales..

Satellite view of rivers

Rivers too show fractal branching

Bolshoi simulation

A simulation of the distribution of dark matter in our universe also shows branching strains

Cortical neurons

the neurons in your brain are finding their connections through fractal branching

Circulatory system

Picture of a living human brain - our body is full of fractals

Traffic

All the roads that are leading to Rome in one picture
