Book Description
National Book Award Finalist: “This man’s ideas may be the most influential, not to say controversial, of the second half of the twentieth century.”—Columbus Dispatch At the heart of this classic, seminal book is Julian Jaynes's still-controversial thesis that human consciousness did not begin far back in animal evolution but instead is a learned process that came about only three thousand years ago and is still developing. The implications of this revolutionary scientific paradigm extend into virtually every aspect of our psychology, our history and culture, our religion—and indeed our future. “Don’t be put off by the academic title of Julian Jaynes’s The Origin of Consciousness in the Breakdown of the Bicameral Mind. Its prose is always lucid and often lyrical…he unfolds his case with the utmost intellectual rigor.”—The New York Times “When Julian Jaynes . . . speculates that until late in the twentieth millennium BC men had no consciousness but were automatically obeying the voices of the gods, we are astounded but compelled to follow this remarkable thesis.”—John Updike, The New Yorker “He is as startling as Freud was in The Interpretation of Dreams, and Jaynes is equally as adept at forcing a new view of known human behavior.”—American Journal of Psychiatry

Book Description
An introduction to computational complexity theory, its connections and interactions with mathematics, and its central role in the natural and social sciences, technology, and philosophy Mathematics and Computation provides a broad, conceptual overview of computational complexity theory—the mathematical study of efficient computation. With important practical applications to computer science and industry, computational complexity theory has evolved into a highly interdisciplinary field, with strong links to most mathematical areas and to a growing number of scientific endeavors. Avi Wigderson takes a sweeping survey of complexity theory, emphasizing the field’s insights and challenges. He explains the ideas and motivations leading to key models, notions, and results. In particular, he looks at algorithms and complexity, computations and proofs, randomness and interaction, quantum and arithmetic computation, and cryptography and learning, all as parts of a cohesive whole with numerous cross-influences. Wigderson illustrates the immense breadth of the field, its beauty and richness, and its diverse and growing interactions with other areas of mathematics. He ends with a comprehensive look at the theory of computation, its methodology and aspirations, and the unique and fundamental ways in which it has shaped and will further shape science, technology, and society. For further reading, an extensive bibliography is provided for all topics covered. Mathematics and Computation is useful for undergraduate and graduate students in mathematics, computer science, and related fields, as well as researchers and teachers in these fields. Many parts require little background, and serve as an invitation to newcomers seeking an introduction to the theory of computation. Comprehensive coverage of computational complexity theory, and beyond High-level, intuitive exposition, which brings conceptual clarity to this central and dynamic scientific discipline Historical accounts of the evolution and motivations of central concepts and models A broad view of the theory of computation's influence on science, technology, and society Extensive bibliography

Book Description
Think of a number between one and ten No, hang on, let's make this interesting. Between zero and infinity. Even if you stick to the whole numbers, there are a lot to choose from - an infinite number in fact. Throw in decimal fractions and infinity suddenly gets an awful lot bigger (is that even possible?) And then there are the negative numbers, the imaginary numbers, the irrational numbers like p which never end. It literally never ends. The world of numbers is indeed strange and beautiful. Among its inhabitants are some really notable characters - pi, e, the square root of minus two and the famous golden ratio to name just a few. Prime numbers occupy a special status. Zero is very odd indeed. And even some apparently common-or-garden integers such as 37 have special properties. Adventures In Mathematics takes a tour of this mind-blowing but beautiful world of numbers and the mathematical rules that connect them. Find out mathematicians' favourite numbers, and the ones they are afraid of (spoiler: it isn't 13). Discover the incredible connection between numbers and the rules of nature. And learn some amazing mathematical tricks that will keep you amused for hours.

WINNER OF THE PULITZER PRIZE • NEW YORK TIMES BESTSELLER • The epic, beloved novel of two boy geniuses dreaming up superheroes in New York’s Golden Age of comics, now with special bonus material by the author—soon to be a Showtime limited series “It's absolutely gosh-wow, super-colossal—smart, funny, and a continual pleasure to read.”—The Washington Post Book World Named one of the 10 Best Books of the Decade by Entertainment Weekly • Finalist for the PEN/Faulkner Award, National Book Critics Circle Award, and Los Angeles Times Book Prize A “towering, swash-buckling thrill of a book” (Newsweek), hailed as Chabon’s “magnum opus” (The New York Review of Books), The Amazing Adventures of Kavalier & Clay is a triumph of originality, imagination, and storytelling, an exuberant, irresistible novel that begins in New York City in 1939. A young escape artist and budding magician named Joe Kavalier arrives on the doorstep of his cousin, Sammy Clay. While the long shadow of Hitler falls across Europe, America is happily in thrall to the Golden Age of comic books, and in a distant corner of Brooklyn, Sammy is looking for a way to cash in on the craze. He finds the ideal partner in the aloof, artistically gifted Joe, and together they embark on an adventure that takes them deep into the heart of Manhattan, and the heart of old-fashioned American ambition. From the shared fears, dreams, and desires of two teenage boys, they spin comic book tales of the heroic, fascist-fighting Escapist and the beautiful, mysterious Luna Moth, otherworldly mistress of the night. Climbing from the streets of Brooklyn to the top of the Empire State Building, Joe and Sammy carve out lives, and careers, as vivid as cyan and magenta ink. Spanning continents and eras, this superb book by one of America’s finest writers remains one of the defining novels of our modern American age.

Book Description
A hilarious reeducation in mathematics-full of joy, jokes, and stick figures-that sheds light on the countless practical and wonderful ways that math structures and shapes our world. In Math With Bad Drawings, Ben Orlin reveals to us what math actually is; its myriad uses, its strange symbols, and the wild leaps of logic and faith that define the usually impenetrable work of the mathematician. Truth and knowledge come in multiple forms: colorful drawings, encouraging jokes, and the stories and insights of an empathetic teacher who believes that math should belong to everyone. Orlin shows us how to think like a mathematician by teaching us a brand-new game of tic-tac-toe, how to understand an economic crises by rolling a pair of dice, and the mathematical headache that ensues when attempting to build a spherical Death Star. Every discussion in the book is illustrated with Orlin's trademark "bad drawings," which convey his message and insights with perfect pitch and clarity. With 24 chapters covering topics from the electoral college to human genetics to the reasons not to trust statistics, Math with Bad Drawings is a life-changing book for the math-estranged and math-enamored alike.

Book Description
Owner of "the most remarkable mind on the planet," (according to Entertainment Weekly) Daniel Tammet captivated readers and won worldwide critical acclaim with the 2007 New York Times bestselling memoir, Born On A Blue Day, and its vivid depiction of a life with autistic savant syndrome. In his fascinating new book, he writes with characteristic clarity and personal awareness as he sheds light on the mysteries of savants' incredible mental abilities, and our own. Tammet explains that the differences between savant and non-savant minds have been exaggerated; his astonishing capacities in memory, math and language are neither due to a cerebral supercomputer nor any genetic quirk, but are rather the results of a highly rich and complex associative form of thinking and imagination. Autistic thought, he argues, is an extreme variation of a kind that we all do, from daydreaming to the use of puns and metaphors. Embracing the Wide Sky combines meticulous scientific research with Tammet's detailed descriptions of how his mind works to demonstrate the immense potential within us all. He explains how our natural intuitions can help us to learn a foreign language, why his memories are like symphonies, and what numbers and giraffes have in common. We also discover why there is more to intelligence than IQ, how optical illusions fool our brains, and why too much information can make you dumb. Many readers will be particularly intrigued by Tammet's original ideas concerning the genesis of genius and exceptional creativity. He illustrates his arguments with examples as diverse as the private languages of twins, the compositions of poets with autism, and the breakthroughs, and breakdowns, of some of history's greatest minds. Embracing the Wide Sky is a unique and brilliantly imaginative portrait of how we think, learn, remember and create, brimming with personal insights and anecdotes, and explanations of the most up-to-date, mind-bending discoveries from fields ranging from neuroscience to psychology and linguistics. This is a profound and provocative book that will transform our understanding and respect for every kind of mind.
