Six Degrees by Duncan J. Watts

This is an interesting, accessible discussion of networks (graphs). I had started Watts's Small Worlds and found it much too hard, and thankfully happened on Six Degrees, which covers many of the same ideas in a clear engaging way. This is a connected age, he says, and we need a science of networks. He covers random networks, small-world networks, scale free networks. He discusses small world searches, epidemics, computer viruses, social cascades.

The book is about the meeting of the theoretical and the practical. It is about a mathematics rooted in relationships, which as such is interesting, essential, and intractable.
