Mensa Guide to Solving Sudoku


Book Description

Here it comes: a revolution in sudoku solving! This is by far the most complete guide to cracking these addictive puzzles ever produced, with tricks even the experts won t know. While most books might have a few pages of introduction before proceeding straight to the sudokus, this one covers it all: hidden pairs, naked pairs, X-wings, jellyfish, squirmbag, bivalue and bilocation graphs, turbot fish, grid coloring, and chains. Every single one is here, and much more too, including the exclusive Gordonian logic methods (Gordonian rectangles and Gordonian polygons) that will turn even the hardest puzzles into a breeze. Of course, there are hundreds of sudoku for practice. A very special addition is a reprint of the very first sudoku ever published in 1979, from "Dell Pencil Puzzles and Word Games" magazine!"




Four Thousand Weeks


Book Description

AN INSTANT NEW YORK TIMES BESTSELLER "Provocative and appealing . . . well worth your extremely limited time." —Barbara Spindel, The Wall Street Journal The average human lifespan is absurdly, insultingly brief. Assuming you live to be eighty, you have just over four thousand weeks. Nobody needs telling there isn’t enough time. We’re obsessed with our lengthening to-do lists, our overfilled inboxes, work-life balance, and the ceaseless battle against distraction; and we’re deluged with advice on becoming more productive and efficient, and “life hacks” to optimize our days. But such techniques often end up making things worse. The sense of anxious hurry grows more intense, and still the most meaningful parts of life seem to lie just beyond the horizon. Still, we rarely make the connection between our daily struggles with time and the ultimate time management problem: the challenge of how best to use our four thousand weeks. Drawing on the insights of both ancient and contemporary philosophers, psychologists, and spiritual teachers, Oliver Burkeman delivers an entertaining, humorous, practical, and ultimately profound guide to time and time management. Rejecting the futile modern fixation on “getting everything done,” Four Thousand Weeks introduces readers to tools for constructing a meaningful life by embracing finitude, showing how many of the unhelpful ways we’ve come to think about time aren’t inescapable, unchanging truths, but choices we’ve made as individuals and as a society—and that we could do things differently.




Ducks, Newburyport


Book Description

WINNER OF THE 2019 GOLDSMITHS PRIZE • SHORTLISTED FOR THE 2019 BOOKER PRIZE • A NEW YORKER BEST BOOK OF 2019 • A NEW YORK TIMES NOTABLE BOOK OF 2019 • A TIME MUST-READ BOOK OF 2019 "This book has its face pressed up against the pane of the present; its form mimics the way our minds move now toggling between tabs, between the needs of small children and aging parents, between news of ecological collapse and school shootings while somehow remembering to pay taxes and fold the laundry."—Parul Sehgal, New York Times Baking a multitude of tartes tatins for local restaurants, an Ohio housewife contemplates her four kids, husband, cats and chickens. Also, America's ignoble past, and her own regrets. She is surrounded by dead lakes, fake facts, Open Carry maniacs, and oodles of online advice about survivalism, veil toss duties, and how to be more like Jane Fonda. But what do you do when you keep stepping on your son's toy tractors, your life depends on stolen land and broken treaties, and nobody helps you when you get a flat tire on the interstate, not even the Abominable Snowman? When are you allowed to start swearing? With a torrent of consciousness and an intoxicating coziness, Ducks, Newburyport lays out a whole world for you to tramp around in, by turns frightening and funny. A heart-rending indictment of America's barbarity, and a lament for the way we are blundering into environmental disaster, this book is both heresy―and a revolution in the novel.




Crossworld


Book Description

Sixty-four million people do it at least once a week. Nabokov wrote about it. Bill Clinton even did it in the White House. The crossword puzzle has arguably been our national obsession since its birth almost a century ago. Now, in "Crossworld," writer, translator, and lifelong puzzler Marc Romano goes where no Number 2 pencil has gone before, as he delves into the minds of the world's cleverest crossword creators and puzzlers, and sets out on his own quest to join their ranks. While covering the American Crossword Puzzle Tournament for the "Boston Globe," Romano was amazed by the skill of the competitors and astonished by the cast of characters he came across--like Will Shortz, beloved editor of the "New York Times" puzzle and the only academically accredited "enigmatologist" (puzzle scholar); Stanley Newman, "Newsday"'s puzzle editor and the fastest solver in the world; and Brendan Emmett Quigley, the wickedly gifted puzzle constructer and the Virgil to Marc's Dante in his travels through the crossword inferno. Chronicling his own journey into the world of puzzling--even providing tips on how to improve crosswording skills--Romano tells the story of crosswords and word puzzles themselves, and of the colorful people who make them, solve them, and occasionally become consumed by them. But saying this is a book about puzzles is to tell only half the story. It is also an explanation into what crosswords tell us about ourselves--about the world we live in, the cultures that nurture us, and the different ways we think and learn. If you're a puzzler, "Crossworld" will enthrall you. If you have no idea why your spouse send so much time filling letters into little white squares, "Crossworld" will tell you - and with luck, save your marriage. CROSSWORLD - by Marc Romano ACROSS 1. I am hopelessly addicted to the "New York Times" crossword puzzle. 2. Like many addicts, I was reluctant to admit I have a problem. 3. The hints I was heading for trouble came, at first, only occasionally. 4. The moments of panic when I realized that I might not get my fix on a given day. 5. The toll on relationships. 6. The strained friendships. 7. The lost hours I could have used to do something more productive. 8. It gets worse, too. DOWN 1.You're not just playing a game. 2. You're constantly broadening your intellectual horizons. 3. You spend a lot of time looking at and learning about the world around you. 4. You have to if you want to develop the accumulated store of factual information you'll need to get through a crossword puzzle. 5. Puzzle people are nice because they have to be. 6. The more you know about the world, the more you tend to give all things in it the benefit of the doubt before deciding if you like them or not. 7. I'm not saying that all crossword lovers are honest folk dripping with goodness. 8. I would say, though, that if I had to toss my keys and wallet to someone before jumping off a pier to save a drowning girl, I'd look for the fellow in the crowd with the daily crossword in his hand.

My Absolute Darling


Book Description

INSTANT NEW YORK TIMES BESTSELLER LA TIMES BOOK PRIZE FINALIST NBCC JOHN LEONARD PRIZE FINALIST ONE OF THE NEW YORK TIMES'S MOST NOTABLE BOOKS OF 2017 ONE OF THE WASHINGTON POST’S MOST NOTABLE BOOKS OF 2017 ONE OF NPR’S ‘GREAT READS’ OF 2017 A USA TODAY BEST BOOK OF THE YEAR AN AMAZON.COM BEST BOOK OF THE YEAR A BUSINESS INSIDER BEST BOOK OF THE YEAR "Impossible to put down." —NPR "A novel that readers will gulp down, gasping.” —The Washington Post "The word 'masterpiece' has been cheapened by too many blurbs, but My Absolute Darling absolutely is one." —Stephen King A brilliant and immersive, all-consuming read about one fourteen-year-old girl's heart-stopping fight for her own soul. Turtle Alveston is a survivor. At fourteen, she roams the woods along the northern California coast. The creeks, tide pools, and rocky islands are her haunts and her hiding grounds, and she is known to wander for miles. But while her physical world is expansive, her personal one is small and treacherous: Turtle has grown up isolated since the death of her mother, in the thrall of her tortured and charismatic father, Martin. Her social existence is confined to the middle school (where she fends off the interest of anyone, student or teacher, who might penetrate her shell) and to her life with her father. Then Turtle meets Jacob, a high-school boy who tells jokes, lives in a big clean house, and looks at Turtle as if she is the sunrise. And for the first time, the larger world begins to come into focus: her life with Martin is neither safe nor sustainable. Motivated by her first experience with real friendship and a teenage crush, Turtle starts to imagine escape, using the very survival skills her father devoted himself to teaching her. What follows is a harrowing story of bravery and redemption. With Turtle's escalating acts of physical and emotional courage, the reader watches, heart in throat, as this teenage girl struggles to become her own hero—and in the process, becomes ours as well. Shot through with striking language in a fierce natural setting, My Absolute Darling is an urgently told, profoundly moving read that marks the debut of an extraordinary new writer.
