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.

Griddlers logic puzzles, also known as Picross or Nonograms, are picture logic puzzles in which cells in a grid have to be colored or left blank according to numbers given at the side of the grid to reveal a hidden picture. Some people compare Griddlers to Sudoku. However, the Griddlers puzzles always reveal a nice image as a result. This book consists of 127 Griddlers and 8 Triddlers puzzles, from small and easy up to big and complicated ones that may take several hours to solve. Seven of them are multigriddlers - one two parts together give one image. The solutions of the puzzles appear at the end of the book.
Through biographical narratives, Claiming Home traces how queer migrant women living in Switzerland navigate often contradictory perspectives on sexuality, gender, and nation. Situated between heteronormative and racialized stereotypes of migrant women on the one hand, and the implicitly white figure of the lesbian on the other, queer migrant women are often rendered ›impossible subjects.‹ Claiming Home maps how they negotiate conflicting loyalties in this field and how they, in their own way, claim a sense of belonging and home.
A master cartoonist and veteran tells the life story of the man who started the second world war Seventy years after his death, Adolf Hitler remains a mystery. Historians, military tacticians, and psychologists have tried in vain to unravel his complex motivations for leading Germany into the Holocaust and World War II. With Shigeru Mizuki's Hitler, the manga-ka (Kitaro, NonNonba, Showa: A History of Japan) delves deep into the history books to create an absorbing and eloquent portrait of Hitler's life. Beginning with Hitler's time in Austria as a starving art student and ending with a Germany in ruins, Shigeru Mizuki's Hitler retraces the path Hitler took in life, coolly examining his charismatic appeal and his calculated political maneuvering. The Munich Beer Putsch, Hitler's ascent to chancellor, the sudden death of his half-niece Geli, the Battle of Stalingrad, his relationship with Eva Braun, and his eventual demise: all are given equal attention in this thorough and compelling biography. In Mizuki's signature style, which populates incredibly realistic backgrounds with cartoony people, Japan's most famous living cartoonist has created an overview of Hitler's life that is as fascinating as it is informative. Translated from the Japanese by Zack Davisson.

The first collection of letters between the two leading figures of the Beat movement Writers and cultural icons Jack Kerouac and Allen Ginsberg are the most celebrated names of the Beat Generation, linked together not only by their shared artistic sensibility but also by a deep and abiding friend­ship, one that colored their lives and greatly influenced their writing. Editors Bill Morgan and David Stanford shed new light on this intimate and influential friendship in this fascinating exchange of letters between Kerouac and Ginsberg, two thirds of which have never been published before. Commencing in 1944 while Ginsberg was a student at Columbia University and continuing until shortly before Kerouac's death in 1969, the two hundred letters included in this book provide astonishing insight into their lives and their writing. While not always in agreement, Ginsberg and Kerouac inspired each other spiritually and creatively, and their letters became a vital workshop for their art. Vivid, engaging, and enthralling, Jack Kerouac and Allen Ginsberg: The Letters provides an unparalleled portrait of the two men who led the cultural and artistic movement that defined their generation.
A transporting, good-humored, and revealing account of Greece's dire troubles, reported from the mountain villages, idyllic islands, and hardscrabble streets that define the country today In recent years, small Greece, often associated with ancient philosophers and marble ruins, whitewashed villages and cerulean seas, has been at the center of a debt crisis that has sown economic and social ruin, spurred panic in international markets, and tested Europe's decades-old project of forging a closer union. In The Full Catastrophe, James Angelos makes sense of contrasting images of Greece, a nation both romanticized for its classical past and castigated for its dysfunctional present. With vivid character-driven narratives and engaging reporting that offers an immersive sense of place, he brings to life some of the causes of the country's financial collapse, and examines the changes, some hopeful and others deeply worrisome, emerging in its aftermath. A small rebellion against tax authorities breaks out on a normally serene Aegean island. A mayor from a bucolic, northern Greek village is gunned down by the municipal treasurer. An aging, leftist hero of the Second World War fights to win compensation from Germany for the wartime occupation. A once marginal group of neo-Nazis rises to political prominence out of a ramshackle Athens neighborhood. The Full Catastrophe goes beyond the transient coverage in the daily headlines to deliver an enduring and absorbing portrait of modern Greece.
