 Six Degrees: The Science of a Connected Age

"Six Degrees: The Science of a Connected Age" is a book written by Duncan J. Watts, published in 2003. The book explores the concept of social networks and the mathematical principles behind them, particularly the idea that any two people on the planet are connected through a short chain of acquaintances—a concept popularly known as "six degrees of separation." Watts delves into various aspects of network theory, examining how information, behaviors, and other phenomena spread through social networks.
