Book excerpt: INTERNATIONAL BESTSELLER • A bestselling dystopian novel that tackles surveillance, privacy and the frightening intrusions of technology in our lives—a “compulsively readable parable for the 21st century” (Vanity Fair). When Mae Holland is hired to work for the Circle, the world’s most powerful internet company, she feels she’s been given the opportunity of a lifetime. The Circle, run out of a sprawling California campus, links users’ personal emails, social media, banking, and purchasing with their universal operating system, resulting in one online identity and a new age of civility and transparency. As Mae tours the open-plan office spaces, the towering glass dining facilities, the cozy dorms for those who spend nights at work, she is thrilled with the company’s modernity and activity. There are parties that last through the night, there are famous musicians playing on the lawn, there are athletic activities and clubs and brunches, and even an aquarium of rare fish retrieved from the Marianas Trench by the CEO. Mae can’t believe her luck, her great fortune to work for the most influential company in the world—even as life beyond the campus grows distant, even as a strange encounter with a colleague leaves her shaken, even as her role at the Circle becomes increasingly public. What begins as the captivating story of one woman’s ambition and idealism soon becomes a heart-racing novel of suspense, raising questions about memory, history, privacy, democracy, and the limits of human knowledge.

Download or read book Human Accomplishment written by Charles Murray and published by Harper Collins. This book was released on 2009-10-13 with total page 790 pages. Available in PDF, EPUB and Kindle. Book excerpt: A sweeping cultural survey reminiscent of Barzun's From Dawn to Decadence. "At irregular times and in scattered settings, human beings have achieved great things. Human Accomplishment is about those great things, falling in the domains known as the arts and sciences, and the people who did them.' So begins Charles Murray's unique account of human excellence, from the age of Homer to our own time. Employing techniques that historians have developed over the last century but that have rarely been applied to books written for the general public, Murray compiles inventories of the people who have been essential to the stories of literature, music, art, philosophy, and the sciences—a total of 4,002 men and women from around the world, ranked according to their eminence. The heart of Human Accomplishment is a series of enthralling descriptive chapters: on the giants in the arts and what sets them apart from the merely great; on the differences between great achievement in the arts and in the sciences; on the meta-inventions, 14 crucial leaps in human capacity to create great art and science; and on the patterns and trajectories of accomplishment across time and geography. Straightforwardly and undogmatically, Charles Murray takes on some controversial questions. Why has accomplishment been so concentrated in Europe? Among men? Since 1400? He presents evidence that the rate of great accomplishment has been declining in the last century, asks what it means, and offers a rich framework for thinking about the conditions under which the human spirit has expressed itself most gloriously. Eye-opening and humbling, Human Accomplishment is a fascinating work that describes what humans at their best can achieve, provides tools for exploring its wellsprings, and celebrates the continuing common quest of humans everywhere to discover truths, create beauty, and apprehend the good.

Download or read book No Medium written by Craig Dworkin and published by MIT Press. This book was released on 2013-02-15 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Close readings of ostensibly “blank” works—from unprinted pages to silent music—that point to a new understanding of media. In No Medium, Craig Dworkin looks at works that are blank, erased, clear, or silent, writing critically and substantively about works for which there would seem to be not only nothing to see but nothing to say. Examined closely, these ostensibly contentless works of art, literature, and music point to a new understanding of media and the limits of the artistic object. Dworkin considers works predicated on blank sheets of paper, from a fictional collection of poems in Jean Cocteau's Orphée to the actual publication of a ream of typing paper as a book of poetry; he compares Robert Rauschenberg's Erased De Kooning Drawing to the artist Nick Thurston's erased copy of Maurice Blanchot's The Space of Literature (in which only Thurston's marginalia were visible); and he scrutinizes the sexual politics of photographic representation and the implications of obscured or obliterated subjects of photographs. Reexamining the famous case of John Cage's 4'33”, Dworkin links Cage's composition to Rauschenberg's White Paintings, Ken Friedman's Zen for Record (and Nam June Paik's Zen for Film), and other works, offering also a “guide to further listening” that surveys more than 100 scores and recordings of “silent” music. Dworkin argues that we should understand media not as blank, base things but as social events, and that there is no medium, understood in isolation, but only and always a plurality of media: interpretive activities taking place in socially inscribed space.

Download or read book Tuttle Learning Chinese Characters written by Alison Matthews and published by Tuttle Publishing. This book was released on 2011-12-20 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: This user-friendly book is aimed at helping students of Mandarin Chinese learn and remember Chinese characters. At last--there is a truly effective and enjoyable way to learn Chinese characters! This book helps students to learn and remember both the meanings and the pronunciations of over 800 characters. This otherwise daunting task is made easier by the use of techniques based on the psychology of learning and memory. key principles include the use of visual imagery, the visualization of short "stories," and the systematic building up of more complicated characters from basic building blocks. Although Learning Chinese Characters is primarily a book for serious learners of Mandarin Chinese, it can be used by anyone with interest in Chinese characters, without any prior knowledge of Chinese. It can be used alongside (or after, or even before) a course in the Chinese language. All characters are simplified (as in mainland China), but traditional characters are also given, when available. Key features: Specially designed pictures and stories are used in a structured way to make the learning process more enjoyable and effective, reducing the need for rote learning to the absolute minimum. The emphasis throughout is on learning and remembering the meanings and pronunciations of the characters. Tips are also included on learning techniques and how to avoid common problems. Characters are introduced in a logical sequence, which also gives priority to learning the most common characters first. Modern, simplified characters are used, with pronunciations given in pinyin. Key information is given for each character, including radical, stroke-count, traditional form, compounds, and guidance on writing the character. This is a practical guide with a clear, concise and appealing layout, and it is well-indexed with easy lookup methods. The 800 Chinese characters and 1,033 compounds specified for the original HSK Level A proficiency test are covered.

Available in PDF, EPUB and Kindle. Book excerpt: An ingenious, masterfully written novel, Thomas Harris's The Silence of the Lambs is a classic of suspense and storytelling and the basis for the Oscar award-winning horror film starring Jodie Foster as Clarice Starling and Anthony Hopkins as Dr. Hannibal Lecter. A serial murderer known only by a grotesquely apt nickname—Buffalo Bill—is stalking particular women. He has a purpose, but no one can fathom it, for the bodies are discovered in different states. Clarice Starling, a young trainee at the F.B.I. Academy, is surprised to be summoned by Jack Crawford, Chief of the Bureau's Behavioral Science section. Her assignment: to interview Dr. Hannibal Lecter, a brilliant psychiatrist and grisly killer now kept under close watch in the Baltimore State Hospital for the Criminally Insane. Lecter's insight into the minds of murderers could help track and capture Buffalo Bill. Smart and attractive, Starling is shaken to find herself in a strange, intense relationship with the acutely perceptive Lecter. His cryptic clues—about Buffalo Bill and about her—launch Clarice on a search that every reader will find startling, harrowing, and totally compelling.
