The Great Book of Riddles: 250 Magnificent Riddles, Puzzles and Brain Teasers


Peter Keyne - 2014
    There are classical logic puzzles, lateral thinking puzzles, “who am I?” riddles, mathematical brain teasers, word ladders, ditloids, and a large selection of illustrated pen and paper, coins, cups, and toothpicks puzzles (please view the preview of this book for a full listing). This is the first time a collection of such breadth has been compiled and formatted especially for Kindle devices. The puzzles have been carefully organized into 25 chapters, and each question is hyperlinked to its solution, to provide utmost ease of navigation. Alongside the world’s most famous riddles, are some lesser known gems, and some brand new puzzles, in print here for the first time. Our aim was to create a definitive compendium of riddles and puzzles to bring enjoyment to people of all ages. We hope you will enjoy unraveling them as much as we enjoyed creating and editing them. Here are a handful of sample riddles: Outside the Box Riddles: You need to divide a round birthday cake into eight pieces, so each of your guests will have something to eat. How can you do this by making only three straight cuts with a knife, and without moving any of the pieces? The king’s two bodyguards developed an ingenious method for assuring the king’s safety. With the king standing between them, they would face in opposite directions; one looking to the west and the other to the east, but at the same time, and without the use of any reflective surfaces, they would both be able to observe the king clearly. How was this possible? Pure Logic Riddles: There are two glasses. One contains water, and the other contains an equal quantity of wine. A teaspoon of water is removed and mixed into the glass of wine. A teaspoon of the wine-water mixture is then removed and mixed into the glass of water. Which of the mixtures is now purer? The sorcerer’s tower was enchanted in such a way that it was able to build itself. Bricks, slates, tiles, and panes of glass, all flew to it of their own accord and danced into position. The tower doubled in size every day until after 100 days it reached a height that provided fine views over the entire realm. How many days did the tower take to reach half its full height? Lateral Thinking Puzzles: Five men are going to church. It starts to rain, and four of the men begin to run. When they arrive at the church, the four men who ran are soaking wet, whereas the fifth man, who didn’t run, is completely dry. How is this possible? Think Twice Riddles: If you are running a race, and you overtake the person in second place, what place do you move into? Word Riddles: SOS is read the same forwards, backwards, and even upside-down. What four-letter word also shares these properties? Number Puzzlers: How many letters are there in the answer to this question? You have an opportunity to buy a hen. In fact, you have been offered a choice between two quite remarkable animals. One of the hens produces six dozen dozen eggs per month, and the other produces a half dozen dozen. Admittedly, both seem impressive. Does it matter which hen you choose? Traditional Poetic Riddles: Five creatures cross a field of snow; But leave a single track behind Whose loops and bows are soon, I know, Unravelled by the mind. Coins, Cups, and Toothpicks Illustrated Riddles: A coin is dropped into an empty bottle and a cork is then inserted in the neck of the bottle. How is it possible to remove the coin without taking out the cork, or breaking the bottle?

Gametek: The Math and Science of Gaming


Geoffrey Engelstein - 2018
    Connecting games to math, science, and psychology, GameTek has grown to be one of the most popular parts of the show.This volume commemorates the anniversary with a collection of over seventy of the best segments, many with annotations and illustrations.With chapters on everything from Rock, Paper, Scissors to the Prisoner’s Dilemma to Player Engagement to Quasicrystals to Buddha’s Forbidden Games, GameTek is sure to delight not just game designers and players, but anyone who wants to learn about the world from a new perspective.Sections:• Game Theory• Math• Psychology• Science• Game Mechanics• Psychology Games• HistoryFrom the first time I heard it, the GameTek segment in The Dice Tower podcast became my favorite part of the show. Listening to Geoff is like going to your favorite lesson with your favorite teacher. He teaches about games (yay!) and does it in a very interesting way with lots of examples. He does amazing stuff. He knows about the construction of games, he knows the theory, he knows all that stuff behind the scenes that we gamers do not see when just playing a game and having fun.Ignacy Trzewiczek, Portal GamesThere are many hobby game 'experts' out there, dying to give you their opinion on how the industry works, how games work, what types of games are best, and so on. Geoff Engelstein is the expert that requires your attention. He is a scholar of games, and his research on games and other principles that apply to gaming is matched by none.Stephen Buonocore, Stronghold GamesOver the years, I’ve listened to a lot of people talk about board games, yet the short snippets that Geoff puts out are the ones that I find myself thinking about in the quiet of the night. His are the segments that you laugh at and say, “I have NO idea what you are talking about” — but later on use to show people just how intellectual you are.Tom Vasel, The Dice Tower

Mathematics and Humor


John Allen Paulos - 1980
    C. Fields, and Woody Allen."Jokes, paradoxes, riddles, and the art of non-sequitur are revealed with great perception and insight in this illuminating account of the relationship between humor and mathematics."—Joseph Williams, New York Times"'Leave your mind alone,' said a Thurber cartoon, and a really complete and convincing analysis of what humour is might spoil all jokes forever. This book avoids that danger. What it does. . .is describe broadly several kinds of mathematical theory and apply them to throw sidelights on how many kinds of jokes work."—New Scientist"Many scholars nowadays write seriously about the ludicrous. Some merely manage to be dull. A few—like Paulos—are brilliant in an odd endeavor."—Los Angeles Times Book Review

Le Ton beau de Marot: In Praise of the Music of Language


Douglas R. Hofstadter - 1997
    Thus, in an elegant anagram (translation = lost in an art), Pulitzer Prize-winning author and pioneering cognitive scientist Douglas Hofstadter hints at what led him to pen a deep personal homage to the witty sixteenth-century French poet Clément Marot.”Le ton beau de Marot” literally means ”The sweet tone of Marot”, but to a French ear it suggests ”Le tombeau de Marot”—that is, ”The tomb of Marot”. That double entendre foreshadows the linguistic exuberance of this book, which was sparked a decade ago when Hofstadter, under the spell of an exquisite French miniature by Marot, got hooked on the challenge of recreating both its sweet message and its tight rhymes in English—jumping through two tough hoops at once. In the next few years, he not only did many of his own translations of Marot's poem, but also enlisted friends, students, colleagues, family, noted poets, and translators—even three state-of-the-art translation programs!—to try their hand at this subtle challenge.The rich harvest is represented here by 88 wildly diverse variations on Marot's little theme. Yet this barely scratches the surface of Le Ton beau de Marot, for small groups of these poems alternate with chapters that run all over the map of language and thought.Not merely a set of translations of one poem, Le Ton beau de Marot is an autobiographical essay, a love letter to the French language, a series of musings on life, loss, and death, a sweet bouquet of stirring poetry—but most of all, it celebrates the limitless creativity fired by a passion for the music of words.Dozens of literary themes and creations are woven into the picture, including Pushkin's Eugene Onegin , Dante's Inferno, Salinger's Catcher in the Rye , Villon's Ballades, Nabokov’s essays, Georges Perec's La Disparition, Vikram Seth's The Golden Gate, Horace's odes, and more.Rife with stunning form-content interplay, crammed with creative linguistic experiments yet always crystal-clear, this book is meant not only for lovers of literature, but also for people who wish to be brought into contact with current ideas about how creativity works, and who wish to see how today’s computational models of language and thought stack up next to the human mind.Le Ton beau de Marot is a sparkling, personal, and poetic exploration aimed at both the literary and the scientific world, and is sure to provoke great excitement and heated controversy among poets and translators, critics and writers, and those involved in the study of creativity and its elusive wellsprings.

Gridlock: Crossword Puzzles and the Mad Geniuses Who Create Them


Matt Gaffney - 2006
    Tens of millions of Americans solve crossword puzzles regularly, but few know a thing about their genesis. Who writes crosswords, how--and for God's sake, why? Matt Gaffney is one of two dozen people who earns a living as a cruciverbalist. In Gridlock he provides an insider's look at the people who put that puzzle in your paper every day. With verve and gusto, Gaffney traces his own starving-artist struggle to find paying puzzle gigs, including marketing hip crosswords to the Gen-X market. He then moves on to topics like the effect of computers on crossword writing, including a man versus machine battle he stages to see who writes better crosswords; the ever-evolving crossword puzzle book market, where a top-selling series now has books shaped like a toilet seat; and a trip to the American Crossword Puzzle Tournament, where the "Cru" (collective slang noun meaning "the crossword puzzle writing community") hangs out in person once a year. Gridlock also features an interview with crossword rock star Will Shortz.

This Idea Must Die: Scientific Theories That Are Blocking Progress


John Brockman - 2015
    In the past, discoveries often had to wait for the rise of the next generation to see questions in a new light and let go of old truisms. Today, in a world that is defined by a rapid rate of change, staying on the cutting edge has as much to do with shedding outdated notions as adopting new ones. In this spirit, John Brockman, publisher of the online salon Edge.org ("the world's smartest website"—The Guardian), asked 175 of the world's most influential scientists, economists, artists, and philosophers: What scientific idea is ready for retirement?Jared Diamond explores the diverse ways that new ideas emerge * Nassim Nicholas Taleb takes down the standard deviation * Richard Thaler and novelist Ian McEwan reveal the usefulness of "bad" ideas * Steven Pinker dismantles the working theory of human behavior * Richard Dawkins renounces essentialism * Sherry Turkle reevaluates our expectations of artificial intelligence * Physicist Andrei Linde suggests that our universe and its laws may not be as unique as we think * Martin Rees explains why scientific understanding is a limitless goal * Alan Guth rethinks the origins of the universe * Sam Harris argues that our definition of science is too narrow * Nobel Prize winner Frank Wilczek disputes the division between mind and matter * Lawrence Krauss challenges the notion that the laws of physics were preordained * plus contributions from Daniel Goleman, Mihaly Csikszentmihalyi, Nicholas Carr, Rebecca Newberger Goldstein, Matt Ridley, Stewart Brand, Sean Carroll, Daniel C. Dennett, Helen Fisher, Douglas Rushkoff, Lee Smolin, Kevin Kelly, Freeman Dyson, and others.

While You're Reading


Gerard Unger - 1997
    This book is about everything that happens while you’re reading – in front of your eyes and inside your head – and about what type designers, typographers and graphic designers bring to a page to make it happen.Renowned type designer Gerard Unger distills decades of design experience into a playful, accessible text that reflects the range of his professional projects, from designing the fonts read daily by millions in USA Today to being responsible for the look of the highway and metro signs in the Netherlands.For Unger, regardless of the application, designers should always consider two important questions: How is it possible to read without seeing any letters? To what extent do all readers possess hidden typographic knowledge? Keeping these two core ideas in mind, Unger explores such topics as legibility, invisible typography, pattern recognition, the reading process, the ergonomics of letterforms, the universe of signs, negative space and typographic illusions.The most seasoned typographers and designers will find as much value in this fresh, first-ever English translation as beginners and the curious who have always wondered how reading happens.

A Field Guide to Lies: Critical Thinking in the Information Age


Daniel J. Levitin - 2016
    We are bombarded with more information each day than our brains can process—especially in election season. It's raining bad data, half-truths, and even outright lies. New York Times bestselling author Daniel J. Levitin shows how to recognize misleading announcements, statistics, graphs, and written reports revealing the ways lying weasels can use them. It's becoming harder to separate the wheat from the digital chaff. How do we distinguish misinformation, pseudo-facts, distortions, and outright lies from reliable information? Levitin groups his field guide into two categories—statistical infomation and faulty arguments—ultimately showing how science is the bedrock of critical thinking. Infoliteracy means understanding that there are hierarchies of source quality and bias that variously distort our information feeds via every media channel, including social media. We may expect newspapers, bloggers, the government, and Wikipedia to be factually and logically correct, but they so often aren't. We need to think critically about the words and numbers we encounter if we want to be successful at work, at play, and in making the most of our lives. This means checking the plausibility and reasoning—not passively accepting information, repeating it, and making decisions based on it. Readers learn to avoid the extremes of passive gullibility and cynical rejection. Levitin's charming, entertaining, accessible guide can help anyone wake up to a whole lot of things that aren't so. And catch some lying weasels in their tracks!
