The intertwining of material culture and social relations becomes the form of a kind of "turbulence".
«Fractals are the result of the breaking down of traditional thought and philosophy that had governed mathematics and the sciences for centuries.
They in turn had a revolutionary effect on diverse sciences, mathematics, philosophy and arts in a very short period of time.
