The best-selling guide to network science, the revolutionary field that reveals the deep links between all forms of human social life A cocktail party. A terrorist cell. Ancient bacteria. An international conglomerate. All are networks, and all are a part of a surprising scientific revolution. In Linked, Albert-Lálórabá, the nation's 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 previously thought. Barabá shows that 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 and the Erdos-Réi model brought the discovery of chaos theory to the general public, Linked tells the story of the true science of the future and of experiments in statistical mechanics on the internet, all vital parts of what would eventually be called the Barabá-Albert model.

Modern astronomical teaching affirms that the world we live on is a globe, which rotates, revolves, and spins away in space at brain-reeling rates of speed; that the sun is a million and a-half times the size of the earth-globe, and nearly a hundred million miles distant from it; that the moon is about a quarter the size of the earth; that it receives all its light from the sun, and is thus only a reflector, and not a giver, of light; that it attracts the body of the earth and thus causes the tides; that the stars are worlds and suns, some of them equal in importance to our own sun himself, and others vastly his superior; that these worlds, inhabited by sentient beings, are without number and occupy space boundless in extent and illimitable in duration; the whole of these interlaced bodies being subject to, and supported by, universal gravitation, the foundation and father of the whole fabric. To fanciful minds and theoretical speculators, the so-called “science” of modern astronomy furnishes a field, unsurpassed in any science for the unrestrained license of the imagination, and the building up of a complicated conjuration of absurdities such as to overawe the simpleton and make him gape with wonder; to deceive even those who truly believe their assumptions to be facts, and to “make men doubt Divine Revelation with as little discrimination as they were formerly called upon to believe.” If the reader will carefully follow and weigh the evidence in the following chapters, he cannot fail to be delivered from the thraldom of popular credulity and led to seek the truth for himself.
