Abstract

Graphical AbstractWe can, for example, understand intimately how the human endocrine systems works, and likewise the chemical nature of compounds present in our environment; but the result of the interaction cannot be deduced from any simple combination of the two knowledge sets: it's not the interacting entities that we should be studying, but the process that creates the phenomena that we witness as a result of this interaction. This is the “biodynamic interface” to which Manish Arora, Alessandro Giuliani and Paul Curtin refer in their article in this issue, and it is a conceptual structure that comes into being upon interaction of entities: a new way to study interactions in complex systems and better understand emergent phenomena.
