Book Description
What do road and railway systems, electrical circuits, mingling at parties, mazes, family trees, and the internet all have in common? All are networks - either people or places or things that relate and connect to one another. Only relatively recently have mathematicians begun to explore such networks and connections, and their importance has taken everyone by surprise. The mathematics of networks form the basis of many fascinating puzzles and problems, from tic-tac-toe and circular sudoku to the 'Chinese Postman Problem' (can he deliver all his letters without traversing the same street twice?). Peter Higgins shows how such puzzles as well as many real-world phenomena are underpinned by the same deep mathematical structure. Understanding mathematical networks can give us remarkable new insights into them all.

Book Description
This book shows that the introduction of the European Credit Transfer System (ECTS) of credit points as a new accounting unit at universities has led to increased bureaucracy and the schoolmaster-style regimentation of Bachelor’s and Master’s courses. It explains how, due to the pressure of having to plan every single working hour of studying in advance, a ‘Sudoku Effect’ is created by the necessity to combine courses, exams and modules in such a way that the points ‘add up’. An unintentional side effect of the introduction of the ECTS, the Sudoku Effect has led to more classroom style teaching, an inflation of exams and fewer choices available to students. It has resulted in such complex and contradictory guidelines for the planning of the curriculum that the values attributed to the higher education reform can often only be realised if the rules for Bachelor’s and Master’s programmes are ignored, or at least stretched, in practice. The book describes how the reaction to this situation is the continuous further refinement of the complicated rules rather than their abolishment.

Book Description
Sudoku For Dummies Volume 3 will offer 240 original and addictive puzzles including new circular and 16 x 16 puzzles to add new dimensions to game play and keep the most avid Sudoku fan entertained. Of the 240 puzzles, 220 are the popular 9x9 puzzles, 10 are 16 x 16, and 10 are circular puzzles. Within each of these categories there are Easy, Tricky, Tough and Diabolical puzzle ratings; and each puzzle is clearly identified with the rating. More than just a listing of puzzles, Sudoku For Dummies, Volume 3 features a chapter explaining how to solve puzzles and the strategies involved. Additionally, readers receive all puzzle solutions in the back of the book. Finally, Sudoku For Dummies, Volume 3 includes a brief history of Sudoku (or Su Doku) for those interested. Descriptions of the puzzles are listed below. Circular Sudoku (10 included: 3 Easy, 3 Tricky, 2 Tough, and 2 Diabolical) The rules are similar to the normal 9x9 Sudoku but with some important differences. The puzzle is circular for a start, with 8 concentric rings. Each ring must contain the numbers 1-8 and each segment running into the centre of the circle and through to the opposite side of the circle must contain the numbers 1 - 8 and or course there can be no duplicate numbers! 16 x 16 Sudoku (10 included: 3 Easy, 3 Tricky, 2 Tough, and 2 Diabolical) The grid is larger at 16 x 16 and solvers must fit the letters A-F into the grid alongside the numbers 0-9. 16 x 16 Sudoku are more difficult, take more time and are more infuriating than the normal puzzles - but just as addictive!
