What mathematical modeling uncovers about life in the city X and the City, a book of diverse and accessible math-based topics, uses basic modeling to explore a wide range of entertaining questions about urban life. How do you estimate the number of dental or doctor's offices, gas stations, restaurants, or movie theaters in a city of a given size? How can mathematics be used to maximize traffic flow through tunnels? Can you predict whether a traffic light will stay green long enough for you to cross the intersection? And what is the likelihood that your city will be hit by an asteroid? Every math problem and equation in this book tells a story and examples are explained throughout in an informal and witty style. The level of mathematics ranges from precalculus through calculus to some differential equations, and any reader with knowledge of elementary calculus will be able to follow the materials with ease. There are also some more challenging problems sprinkled in for the more advanced reader. Filled with interesting and unusual observations about how cities work, X and the City shows how mathematics undergirds and plays an important part in the metropolitan landscape.

Everyone loves sudoku puzzles, finding them impossible to put down. The only problem: having enough sudokus to solve! Created in the United States, these addictive conundrums were originally called "Number Place" puzzles until their recent rise in popularity in Japan, where the name translated as sudoku. However, in a true sudoku, unlike a "Number Place" puzzle, the grids are symmetrical. This trait makes for a more elegant solve. Every puzzle included inside is symmetrical, which is not always the case in other sudoku books. In this "Martial Arts Sudoku" series, we've indicated the skill level necessary to complete each book in the same way Japanese karate levels are ranked: by different colored belts. This is the Second-Degree Black Belt volume, filled with puzzles that will provide a sly, absorbing test for even the best, most proficient experts. You'll go crazy for these super engaging brain bafflers!
