A.L. Barabasi and networks In the fall of 1994. with a fresh doctorate in theoretical hysics, I had started as a postdoc in IBM Watson Research Center. I checked out from the library a general-audience book on computer sciences to read over the Christmas break. As I immersed myself in algorithms and graphs, I started to sense how little was known about networks in general. All my readings told me that the.network formed a fundamentally random network. The more I thought about it the more i was convinced that there must be some organizing principles governing the complex webs around us

A.L. Barabasi and networks Dreaming of identifying some signature of order, I started to study network theory beginning with the classical works of Erdos and renyi. Before I left IBM in the fall of 1995 for a faculty position in physics at Univ of Notre Dame, I had submitted my first research paper about complex networks. At Notre dame.i tried with little success to contact search engines for data on the Web's topology Under pressure to publish and obtain grants, I gradually replaced networks with safer and more conventional research
