Sudoku X also called Diagonal Sudoku.The puzzle is a 6x6 grid made up of 3x2 subgrids (called "regions").Some cells already contain numbers, known as "givens".The goal is to fill in the empty cells, one number in each, so that each column, row, region and diagonal contains the numbers 1 through 6 exactly once.Each number in the solution therefore occurs only once in each of three "directions", hence the "single numbers" implied by the puzzle's name.

Packed with more than a hundred color illustrations and a wide variety of puzzles and brainteasers, Taking Sudoku Seriously uses this popular craze as the starting point for a fun-filled introduction to higher mathematics. How many Sudoku solution squares are there? What shapes other than three-by-three blocks can serve as acceptable Sudoku regions? What is the fewest number of starting clues a sound Sudoku puzzle can have? Does solving Sudoku require mathematics? Jason Rosenhouse and Laura Taalman show that answering these questions opens the door to a wealth of interesting mathematics. Indeed, they show that Sudoku puzzles and their variants are a gateway into mathematical thinking generally. Among many topics, the authors look at the notion of a Latin square--an object of long-standing interest to mathematicians--of which Sudoku squares are a special case; discuss how one finds interesting Sudoku puzzles; explore the connections between Sudoku, graph theory, and polynomials; and consider Sudoku extremes, including puzzles with the maximal number of vacant regions, with the minimal number of starting clues, and numerous others. The book concludes with a gallery of novel Sudoku variations--just pure solving fun! Most of the puzzles are original to this volume, and all solutions to the puzzles appear in the back of the book or in the text itself. A math book and a puzzle book, Taking Sudoku Seriously will change the way readers look at Sudoku and mathematics, serving both as an introduction to mathematics for puzzle fans and as an exploration of the intricacies of Sudoku for mathematics buffs.

The acclaimed author explores the hidden crises of Gen X women in this “engaging hybrid of first-person confession, reportage [and] pop culture analysis” (The New Republic). Ada Calhoun was married with children and a good career—and yet she was miserable. She thought she had no right to complain until she realized how many other Generation X women felt the same way. What could be behind this troubling trend? To find out, Calhoun delved into housing costs, HR trends, credit card debt averages, and divorce data. At every turn, she saw that Gen X women were facing new problems as they entered middle age—problems that were being largely overlooked. Calhoun spoke with women across America who were part of the generation raised to “have it all.” She found that most were exhausted, terrified about money, under-employed, and overwhelmed. And instead of being heard, they were being told to lean in, take “me-time,” or make a chore chart to get their lives and homes in order. In Why We Can’t Sleep, Calhoun opens up the cultural and political contexts of Gen X’s predicament. She offers practical advice on how to ourselves out of the abyss—and keep the next generation of women from falling in. The result is reassuring, empowering, and essential reading for all middle-aged women, and anyone who hopes to understand them.
