Fractals and the art of roughness

What appears messy and irregular in nature, like coastlines or cauliflowers, actually follows deep mathematical order. Fractal geometry exposes self-similar patterns that repeat at every scale, allowing roughness to be measured with a single number. From the branching of lungs to financial market swings, this approach uncovers structure where only confusion seemed to exist. Even the most complex shapes can spring from simple, endlessly repeated rules, leading to forms of surprising beauty and harmony.
