Cauliflower and fractals

Researchers have published a mathematical formula to describe the processes that dictate how cauliflower-like fractals form [1].

The team grew thin films using a technique known as chemical vapour deposition (CVD). They adapted the CVD process so that the film would grow into shapes similar to those seen on a cauliflower. These structures were on the submicron scale.

From this work the team were able to derive the formula which describes how the cauliflower-like patterns develop over time.

Theory verses Experiment

Below are some graphics comparing the theory with experimental observations. The close agreement is clear.
