Nexus: Small Worlds and the Groundbreaking Science of Networks Reprint Edition
Purchase options and add-ons
As Chaos explained the science of disorder, Nexus reveals the new science of connection and the odd logic of six degrees of separation.
"If you ever wanted to know how many links connect you and the Pope, or why when the U.S. Federal Reserve Bank sneezes the global economy catches cold, read this book," writes John L. Casti (Santa Fe Institute). This "cogent and engaging" (Nature) work presents the fundamental principles of the emerging field of "small-worlds" theory―the idea that a hidden pattern is the key to how networks interact and exchange information, whether that network is the information highway or the firing of neurons in the brain. Mathematicians, physicists, computer scientists, and social scientists are working to decipher this complex organizational system, for it may yield a blueprint of dynamic interactions within our physical as well as social worlds.Highlighting groundbreaking research behind network theory, "Mark Buchanan's graceful, lucid, nontechnical and entertaining prose" (Mark Granovetter) documents the mounting support among various disciplines for the small-worlds idea and demonstrates its practical applications to diverse problems―from the volatile global economy or the Human Genome Project to the spread of infectious disease or ecological damage. Nexus is an exciting introduction to the hidden geometry that weaves our lives so inextricably together.

Mark Buchanan manages to keep the delicate balance between intuitive understanding and rigorous analysis; a balance that most popular science books I have read fail to keep. Thus it offers both an intruiging and stimulating read as well as a truly convincing and enlightening scientific argument (beat that you postmodern pseudoscientists!) Another mark of its excellence is that while doing its declared tast it simultaneously treats the reader a veritable tour de force of the collected scientific wisdom of the modern world. In that it reminds of another excellent recent book, namely The Da Vinci Code by Dan Brown. Both books thus have plenty of added value and are a feast for the senses as well as the mind.
At the same time the book manages to infuse the reader with a sense of optimism about the future of science and humankind; an important accomplishment given the many attacks that science has received lately by many pessimistic and nihilistic postmodernists. This fact also makes the book the more enjoyable; few people really want to read pessimistic monologues. In conclusion: everybody with an interest in social or physical networks should read it. This is a theory of tremendous explanatory power. A prime nobel prize candidate.
When all the elements in a small-world network have a comparable number of links, they are called "egalitarian," but some "aristocratic" small-world networks also have hub elements which are more highly linked (according to a power law or "fat tail" relationship). Either way, small-world networks tend to be efficient and robust, although they are also vulnerable to disfunction or complete collapse if a significant percentage of their weak links or hub elements are lost.
The above summarizes the basic concept, which Buchanan fleshes out with many examples spanning many fields (biology, economics, physics, epidemiology, information technology, business, politics, etc.), and he also adds a human-interest element by telling us about specific researchers and their working relationships. Buchanan is a top-notch science writer, and so he relays all of this in an effective and entertaining manner.
The only downside is that the book format gives it more of the feel of a novel rather than a textbook, so key points are not highlighted and it's difficult to go back and find information. I think this is a significant downside because it hinders the serious reader who wants to use the book as a reference and explore the topic further, so I'm giving the book a four-star rating instead of five. However, I still highly recommend the book to readers who are interested in general popular science, and especially network theory. This topic has an important place in the broader and increasingly important subject of complexity theory.
Just like what the author suggests in the book, the study of world phenomenon under the context of physics is still at its new-born stage. Please do not expect too high. But that would never reduce the meaning of such academic field to our world. It opens our eyes by leading us to a drastically different perspective with which human beings can view the world.
For instance, if later and further experiments and studies prove that the distribution of wealth must be the way it is now (i.e. much wealth in hands of a small group) since it is one of the laws followed by the world, then the arguments of left and right will become totally meaningless. The main question for human beings will then be how should all of us live our lives, given whatever position we are situated along the scale of wealthiness.
Also, one should not forget that, as warned by the author, that the concentration of wealth will get worse and irrevertible when the system fails to regulate the misuse of power brought by the accumulated wealth so that it passes the tipping point. This is the most impressive revelation that I had found in the book.
The book is so good that I have just got one from Amazon to fill my collection.
