This book looks at classic puzzles from the perspective of their structures and what they tell us about the brain. It uses the work on the neuroscience of mathematics from Dehaene, Butterworth, Lakoff, Núñez, and many others as a lens to understand the ways in which puzzles reflect imaginative processes blended with rational ones. The book is not about recreational or puzzle-based mathematics in and of itself but rather about what the classic puzzles tell us about the mathematical imagination and its impact on the discipline. It delves into the history of classic math puzzles, deconstructing their raison d’être and describing their psychological features, so that their nature can be fleshed out in order to help understand the mathematical mind. This volume is the first monographic treatment of the psychological nature of puzzles in mathematics. With its user-friendly technical level of discussion, it is of interest to both general readers and those who engage in the disciplines of mathematics, psychology, neuroscience, and/or anthropology. It is also ideal as a textbook source for courses in recreational mathematics, or as reference material in introductory college math courses.

"The New York Times" and its crossword puzzle editor bring readers this volume, overflowing with 200 selected crosswords from the pages of the "Times," puzzles free of the obscure trivia of older crosswords, and full of modern, fresh vocabulary and fun wordplay.

A riveting psychological drama that challenges the way we understand others—and our own sense of self Mia is a schoolteacher in Denmark. Her husband, Frederik, is the charismatic headmaster of a local private school. During a vacation on Majorca, they discover that a brain tumor has started to change Frederik's personality. As it becomes harder and harder for Mia to recognize him, she must protect herself and their teenage son from the strange, blunted being who now inhabits her husband's body—and with whom she must share her home, her son, and her bed. When millions of crowns go missing at the private school, Frederik is the obvious culprit, and Mia's private crisis quickly draws in the entire community. Frederick's new indifference and lack of inhibition rupture long-standing friendships, isolating Mia and making her question who Frederik really is. Was the tumor already affecting him during the years they had been so happy together? And does it excuse Frederik from fraud? Mia enlists the help of a lawyer named Bernhard, whom she meets in a support group for spouses of people with brain injuries. As they prepare Frederik's defense, the two of them wrestle with the latest brain research, the age-old question of free will—and their growing attraction to each other. Jungersen's lithe prose and unexpected plot twists will keep readers hooked until the very last page.
