Scientists believe that without the dual to entropy, life will remain a mystery. At the beginning of the 1930s, Luigi Fantappiè saw the possibility of interpreting the advanced potentials of the wave equation as a new category of phenomena, totally different from the entropic phenomena which respond to the principle of causality. He named these phenomena syntropic, and could see them in the living systems. Although Fantappiè was among the foremost mathematicians, the finalistic properties of syntropy were considered outside science. In 2010 Antonella Vannini provided the experimental proof to this theory opening science to a new type of causality and to a new explanation of life.
