Description

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, Barabási, 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 Barabási, can shed light on the robustness of the Internet, the spread of fads and viruses, even the future of democracy.… (more)

An interesting book on network theory. The author nicely takes you through the evolutions of thought around the ways networks are organized, building up to the current theory of complex networks that relatively accurately models things like the internet. Complex networks are arranged with links between nodes. If we're thinking about the internet, then each node is a website and the links are the, well, links between them. Different nodes have different levels of fitness (mathematically defined as the likelyhood that it will be linked to, but practically just how good is the website), resulting in certain nodes (ex. Google, Amazon, Wikipedia) becoming hubs in the network, doing much of the work of interconnectivity for the entire thing.

The book lays out this theoretical framework very well, and it does seem accurate. The most interesting thing about the book to me, though, was its discussion of some of the implications of this. The existence of hubs means that the connectivity of a network is inordinately maintained by certain nodes and that means that those nodes are critical if you want to either protect or destroy the network. This means, for example, that some banks could be "too big to fail," because if their connectivity were lost the entire system would go out. Even more problematic, I thought, was Barbasi's discussion of the AIDS virus - HIV spreads through a network of sexual connectivity that follows this network pattern. To stop the spread of the disease you would want to interrupt this network. If there is limited treatment available (as there is in many parts of Africa, for example) network theory requires that the most promiscuous nodes have priority for treatment. Logical, but ethically weird to me.

Anyway, overall this was a very good book. It explained its topic well and gave me plenty to think about. Four stars.

The phenomenon of networks in everyday life: from social networks to the web. How networks are organized and how they change, react to attacks or why they sometimes collapse. Nicely told with examples out of politics, maths, and mostly from the web.

After reading Mitchel Resnick's Turtles, Termites, and Traffic Jams: Explorations in Massively Parallel Microworlds (Complex Adaptive Systems), my exploration of decentralized networks went down a very viral path. This book, in particular, discusses the application of network theory in the context of its historical significance. The author explores how it can be used as a tool and device to understand cities, computer networks social networks, human-human interactions (speech), human-computer interactions (HCI), computer-computer interactions (protocol), diseases, computer viruses, nature. Based on this book and its related siblings, it inspires tremendous amounts of ideas for the next big thing in marketing strategy.… (more)

Pretty good.

I love reading about accessible abstract ways of interpreting all sorts of phenomena.

The third (in order of reading by me) recent book on "small worlds" and related stuff such as WWW structure.

Overall I enjoyed this book, but I found the examples from the social sciences most compelling because this was my interest in the book. I borrowed this book from the Stillwater Public Library.

interesting book on how different networks perform in similar ways. Author discusses biological networks, computer networks, people networks, discusses how different networks have different characteristics as, there are three main architectures of networ

Another one on the "required reading" list for library school. An engaging read.

I cannot say I understood fully all that Barabási had to say, or even was able to retain all that thought I understood at the time I read it, but still and all, I am extremely glad I tackled his books. It is really quite readable! He begins it so gently, carrying even the non-mathematicians, non-physicists, and non-scientists into more and more complexity. Our understanding of our world is gaining on our ignorance! I feel I need to at least make an attempt to keep up!… (more)

This is one of the most pleasant scientific reads in form of a book I have the pleasure to read had. The introduction to networks is very clever, not starting directly with science but rather introudcing all the basic and necessary conceptd, scientists and problems present in network theory. Hving presentef this the authors describes network research from a chronological poont of view, where it is very easy to understand all the new discovered concepts and the necessity of them. I have rarely had access to such pleasant literature. The book finishes describing thet last advances in network theory and paves the ground for the next conceptual step, which is networks dynamics.

My only concern is whether his papers are so well written and whether other books like this can be easily found in research areas that interest me like quantum interactions, doking, and so on.

It would have been really difficult to read from scratch a paper from this Albertq, without all this interesting introductions.

Now i am going to check the current status of his research and start to think how my research could benefit from his insights.

For me the book went too far in story telling details: I was bored by the small details of who did what in the morning of a day before doing something that the writer would like to mention. And generally, the whole book could have been shorter.

It was interesting to read about he topology of networks for a while, but when he started talking about the revolution these things will make to science (actually, he mentiones areas specifically), well, then I felt that this reminds me a hype. Of course, I cannot judge it, but he didn't convince me.

E.g. he starts talking about September the 11th, terrorists networks, coming to the conclusion - without using practically any knowledge of networks - that the only way of stopping terrorists is to cease the causes, so that noone wants to join a terrorists network. Yes, that would really be a revolution.
