Barabasi has been a major contributor to the development of real-world network, together with several other scientists from physics, mathematics, and computer science. Barabasi's biggest role has been the introduction of the Scale-free Network concept, as well as a popularizer of network theory. Among the topics in network theory that Barabasi has studied are growth and preferential attachment, the mechanisms responsible for the structure of the World Wide Web or the cell. According to the review of one of Barabasi's books, preferential attachment can be described as follows: "Barabasi has found that the websites that form the network (of the WWW ) have certain mathematical properties. The conditions for these properties to occur are threefold. The first is that the network has to be expanding, growing. This precondition of growth is very important as the idea of emergence comes with it. It is constantly evolving and adapting. That condition exists markedly with the world wide web. The second is the condition of preferential attachment, that is, nodes (websites) will wish to link themselves to hubs (websites) with the most connections. The third condition is what is termed competitive fitness which in network terms means its rate of attraction. BOOKS
