Description:
A cocktail party. A terrorist cell. Ancient bacteria. An international conglomerate. All are networks, and all are a part of a surprising scientific revolution. Albert-Laszlo Barabasi, the nations foremost expert in the new science of networks, takes us on an intellectual adventure to prove that social networks, corporations, and living organisms are more similar than previoulsy thought. Grasping a full understanding of network science, will someday allow us to design blue chip businesses, stop the outbreak of deadly diseases, and influence the exchange of ideas and information. Just as James Gleick brought the discovery of the Chaos theory to the general public, Linked tells the story of the true science of the future.
