The Big Sudoku Book has received another review, and in an unexpected venue: The Wall Street Journal! The review is by Keith Devlin, a mathematician at Stanford University and the author of a small library of books of his own. Devlin writes:
The authors show vividly that mathematics is really about the power of abstraction, the push to explain as much as possible in the most compact form possible. Numbers and arithmetic are a part of that enterprise, but there is a lot more besides. “Taking Sudoku Seriously” is an excellent vehicle whereby devotees of the puzzle can come to understand the nature of mathematics.
