LINKED: Network science and the diffusion of innovations

Physicist Albert-Laszlo Barabasi's new book Linked: The New Science of Networks demolishes many of the assumptions about networks--human, computer, and biological--that have prevailed, often unconsciously, for a long time.

Networks consist of nodes and links. In social networks for example, people are the nodes, and relationships are the links. That networks consist of a more-or-less random arrangement of nodes and links is often assumed.
