The “New” Science of Networks

In recent years, the analysis and modeling of networks, and also networked dynamical systems, have been the subject of considerable interdisciplinary interest, yielding several hundred papers in physics, mathematics, computer science, biology, economics, and sociology journals ( Newman 2003c ), as well as a number of books ( Barabasi 2002 , Buchanan 2002 , Watts 2003 ). Here I review the major findings of this emerging field and discuss briefly their relationship with previous work in the social and mathematical sciences.
