As Chaos defined the technological know-how of illness, Nexus finds the hot technology of connection and the peculiar good judgment of six levels of separation.

"If you ever desired to know the way many hyperlinks attach you and the Pope, or why while the U.S. Federal Reserve financial institution sneezes the worldwide financial system catches chilly, learn this book," writes John L. Casti (Santa Fe Institute). This "cogent and fascinating" (Nature) paintings offers the elemental rules of the rising box of "small-worlds" theory—the concept that a hidden trend is the major to how networks engage and alternate details, even if that community is the data street or the firing of neurons within the mind. Mathematicians, physicists, machine scientists, and social scientists are operating to decipher this complicated organizational process, for it could possibly yield a blueprint of dynamic interactions inside of our actual in addition to social worlds.

Highlighting groundbreaking study in the back of community concept, "Mark Buchanan's sleek, lucid, nontechnical and exciting prose" (Mark Granovetter) records the mounting aid between a number of disciplines for the small-worlds concept and demonstrates its sensible purposes to different problems—from the risky international economic system or the Human Genome venture to the unfold of infectious disorder or ecological harm. Nexus is an exhilarating creation to the hidden geometry that weaves our lives so inextricably jointly.
