Networks all have a meaningful similarity. Whether the network at hand is a party, a cell's molecular reaction, or the puzzling old bridges of Königsberg, Prussia, you could describe each one by using a branch of mathematics called “graph theory,” invented by Leonhard Euler in 1736. His long-dormant concept bloomed in the 1990s with the advent of the Internet and continues to yield insights into many important problems. Sounds a bit dry? Don't worry. Albert-László Barabási writes in a lively style (there's nary an equation in sight) with fun, informative anecdotes. The tale of how he and other scientists discovered "the laws of networks" unfolds like a detective story. After reading this book, you'll see networks everywhere and gain deeper insight into disparate phenomena, from biological systems to business organizations to the economics of "increasing returns." getAbstract recommends this clear, accessible book to anyone who has ever wondered about the ubiquitous webs that encompass all things. This is popular science at its best.

In this summary, you will learn

  • How a simple mathematical model describes many real-world networks
  • How this model applies to business, technology, social organization and many other areas
  • How networks grow
  • How networks fail


Connecting the Dots
Until 1875, the branches of the Pregel River split the city of Königsberg, Prussia, into four pieces. Seven bridges connected the pieces: Five crossed to an island in the middle of the river and two crossed branches of the river. These bridges gave rise to the following...
