Linked: The New Science of Networks [Englisch] [Gebundene Ausgabe]

How is the human brain like the AIDS epidemic? Ask physicist Albert-László Barabási and he'll explain them both in terms of networks of individual nodes connected via complex but understandable relationships. Linked: The New Science of Networks is his bright, accessible guide to the fundamentals underlying neurology, epidemiology, Internet traffic, and many other fields united by complexity.

Barabási's gift for concrete, nonmathematical explanations and penchant for eccentric humor would make the book thoroughly enjoyable even if the content weren't engaging. But the results of Barabási's research into the behavior of networks are deeply compelling. Not all networks are created equal, he says, and he shows how even fairly robust systems like the Internet could be crippled by taking out a few super-connected nodes, or hubs. His mathematical descriptions of this behavior are helping doctors, programmers, and security professionals design systems better suited to their needs. Linked presents the next step in complexity theory--from understanding chaos to practical applications. --Rob Lightner

Highlighted in Mark Buchanan's Nexus [BKL My 1 02] as a key researcher on networks, Barabasi here talks about his work in more detail. In an anecdotal narrative, he traces networks' mathematical parentage back to Leonhard Euler and the late Paul Erdos, two biographically as well as mathematically interesting geniuses. They set a foundation called graph theory, on which some sociologists in the late 1960s and early 1970s built ideas of how a social network functions; the phrase "six degrees of separation" arose out of their work. Amusing readers with what helped boost that phrase into general circulation--a Web site that calculates the movie-credit connections between Kevin Bacon and any other Hollywood actor--Barabasi then shifts to his own fascinating studies of the Web. His research group found that its domination by hub sites like Hotmail or Yahoo adheres to a graphical relation called the "power law." Limning this property in contexts such as Vernon Jordan's links among corporate boards, Barabasi imparts the central concepts of networks. Gilbert Taylor

"Captivating...Linked is a playful, even exuberant romp through an exciting new field."

The first book to explore the hot new science of networks and their impact on nature, business, medicine, and everyday life. }In the 1980's, James Gleick's Chaos introduced the world to complexity. Now, Albert-Lszl Barabsi's Linked reveals the next major scientific leap: the study of networks. We've long suspected that we live in a small world, where everything is connected to everything else. Indeed, networks are pervasive--from the human brain to the Internet to the economy to our group of friends. These linkages, it turns out, aren't random. All networks, to the great surprise of scientists, have an underlying order and follow simple laws. Understanding the structure and behavior of these networks will help us do some amazing things, from designing the optimal organization of a firm to stopping a disease outbreak before it spreads catastrophically.In Linked, Barabsi, a physicist whose work has revolutionized the study of networks, traces the development of this rapidly unfolding science and introduces us to the scientists carrying out this pioneering work. These "new cartographers" are mapping networks in a wide range of scientific disciplines, proving that social networks, corporations, and cells are more similar than they are different, and providing important new insights into the interconnected world around us. This knowledge, says Barabsi, can shed light on the robustness of the Internet, the spread of fads and viruses, even the future of democracy. Engaging and authoritative, Linked provides an exciting preview of the next century in science, guaranteed to be transformed by these amazing discoveries.From Linked:This book has a simple message: think networks. It is about how networks emerge, what they look like, and how they evolve. It aims to develop a web-based view of nature, society, and technology, providing a unified framework to better understand issues ranging from the vulnerability of the Internet to the spread of diseases. Networks are present everywhere. All we need is an eye for them...We will see the challenges doctors face when they attempt to cure a disease by focusing on a single molecule or gene, disregarding the complex interconnected nature of the living matter. We will see that hackers are not alone in attacking networks: we all play Goliath, firing shots at a fragile ecological network that, without further support, could soon replicate our worst nightmares by turning us into an isolated group of species...Linked is meant to be an eye-opening trip that challenges you to walk across disciplines by stepping out of the box of reductionism. It is an invitation to explore link by link the next scientific revolution: the new science of networks. }
