Emergence occurs when an entity is observed to have properties its parts do not have on their own. These properties or behaviors emerge only when the parts interact in a wider non trivial network. Networks are everywhere around us and in us. There are social networks, computer networks (internet), our brain and cell’s biological networks, gene regulatory networks, semantic networks, predatory networks in nature, networks of cities and companies etc. Networks facilitate a field, a self organising force that constitutes the very essence of all living. These networks are mostly scale free, that is a network whose degree distribution follows a power law, which means that the probability for a node to have k connections is roughly k^(-g) where g is a constant mostly between 1 and 4. Despite the many differences of these networks and their constituents on the surface, they are seemingly scaled versions of each other both in structure and dynamics. Ranging from questions of how many hours do we need to sleep, to how many times our hearts beat in a lifetime, to developments and life cycles of cities and companies, or dynamics of biological predatory networks, or how memes are spreading on social networks, these are all governed by scale free network phenomena dancing to the same simple tune, however diverse and unrelated they may seem.
