The secret of fractal objects ... 

The fractal methodology is used in medicine, biology, physics, meteorology, etc. It consists in exploiting the fractality that resides in an autonomous system to understand the evolution of the dynamics of the system at different scales. For example, the heart receives a lot of information from its multiple vessels subdivided fractally. Each vessel sends a flow that goes back to the heart muscle which instantly orders those information in a steady beat while ensuring gas exchange. 

In terms of forecasts, the indicator of an accelerated heart rate may correspond to the intensity of physical exertion.

However, during periods of intense sport, turbulence, the normal law does not manage to capture the thick tails of distribution. Traditional methods of predicting such an indicator, use the normal law. Only fractal laws account for a laminar or turbulent state of the dynamic system. This is the reason why the fractal methodology is more precise than the traditional method which is a particular case.
