Networks are everywhere, from mobile communication and business relations to proteins and epidemics. In the discussion of the greatest challenges and opportunities that humanity faces networks invariably form a central part of the discussion. Networks are everywhere, or are they? Rather it seems that humans, not just scientists but the population in general, has discovered networks as suitable metaphor that helps us deal with the increasing complexity of the works we live in. In this talk I will try to link mathematical insights with philosophical perspectives, and experiences from several recent art projects. The main point I would like to make is that our collective fascination with networks stems indeed from a common source: The ability of networks to represent complexity and understand emergent properties.
