Nets, Puzzles, and Postmen

• Networks are everywhere - wherever people and things relate and connect to one another: from social networks and the internet, to ancient mazes, secret codes, and even the genetic structure of life itself.
• Peter Higgins explains how mathematics can give us rich and surprising insights into the workings of networks of all types.
• Circular Sudoku and the 'Chinese Postman Problem' (can he deliver all his letters without traversing the same street twice?) are just some of the fascinating and classic mathematical puzzles that are explored here.
• Uses a minimum of technical language - the mathematics emerges naturally and accessibly through the examples used.

Readership: Anyone interested in mathematics, or in the mathematical basis of real-world networks (e.g. those interested in the internet, economists, social scientists, etc). General readers of popular mathematics books and mathematical puzzles.

Peter M Higgins, Professor and Head of the Department of Mathematical Sciences, University of Essex
