    On Antiques Roadshow, experts tell people whether they have a "match" and are in possession of a valuable antique or simply have another run-of-the-mill object. Leigh and Leslie Keno, the twin-brother experts who appear on Antiques Roadshow, have now written a book chronicling their history of discovering rare antiques -- Hidden Treasures: Searching for Masterpieces of American Furniture.These brothers have literally spent a lifetime learning about antiques. By the time the boys were 12, they were already dealers and were more than a bit familiar with the world of flea markets, tag sales, and antique shops. Having been raised in a home where they learned that the intrinsic value of an antique lies in its rarity and beauty, the brothers took that knowledge and built a life around what quickly became an obsession.In Hidden Treasures the Kenos' passion is not explained in a dry, academic lecture; instead, they detail some of the most exciting antiques hunts they've had. Although they are both obviously experts, there are still pieces that experts can question or pass over because years of refinishing and reupholstering have disguised the original design. Sometimes even experts can feel like they're on the other side of the table at Antiques Roadshow. In Hidden Treasures the Kenos face some trials, but their skill and determination always leads them to success.The brothers, who alternate writing chapters, don't simply want to tell readers about the fun they have -- they want the readers to understand antiques. Hidden Treasures is filled with photographs of the rare and beautiful pieces discussed in the text. Many of the pieces are shown in a series of photographs to explain exactly why those pieces are works of such incredible craftsmanship.Reading Hidden Treasures will not turn someone into the experts that Leigh and Leslie are. But it does allow for a much greater understanding of the antiques world that they love. They teach readers to appreciate the beauty that can transform an everyday object into a work of art, and in doing so, they teach readers to keep their eyes open to the beauty that people miss every day.

    Widely accepted as the authoritative text and reference on electronic circuit design, both analog and digital, this book revolutionized the teaching of electronics by emphasizing the methods actually used by circuit designers -- a combination of some basic laws, rules of thumb, and a large bag of tricks. The result is a largely nonmathematical treatment that encourages circuit intuition, brainstorming, and simplified calculations of circuit values and performance. The new Art of Electronics retains the feeling of informality and easy access that helped make the first edition so successful and popular. It is an ideal first textbook on electronics for scientists and engineers and an indispensable reference for anyone, professional or amateur, who works with electronic circuits.

    Following a brief account of the historical relationship between structuralism and poststructuralism, this Very Short Introduction traces the key arguments that have ledpoststructuralists to challenge traditional theories of language and culture. While the author discusses such well-known figures as Barthes, Foucault, Derrida, and Lacan, she also draws pertinent examples from literature, art, film, and popular culture, unfolding the poststructuralist account ofwhat it means to be a human being.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics. Written by experts for the newcomer, they demonstrate the finest contemporary thinking about the central problems and issues in hundredsof key topics, from philosophy to Freud, quantum theory to Islam

    The book details the major subsystems and features of the Linux kernel, including its design, implementation, and interfaces. It covers the Linux kernel with both a practical and theoretical eye, which should appeal to readers with a variety of interests and needs. The author, a core kernel developer, shares valuable knowledge and experience on the 2.6 Linux kernel. Specific topics covered include process management, scheduling, time management and timers, the system call interface, memory addressing, memory management, the page cache, the VFS, kernel synchronization, portability concerns, and debugging techniques. This book covers the most interesting features of the Linux 2.6 kernel, including the CFS scheduler, preemptive kernel, block I/O layer, and I/O schedulers. The third edition of Linux Kernel Development includes new and updated material throughout the book:An all-new chapter on kernel data structuresDetails on interrupt handlers and bottom halvesExtended coverage of virtual memory and memory allocationTips on debugging the Linux kernelIn-depth coverage of kernel synchronization and lockingUseful insight into submitting kernel patches and working with the Linux kernel community

    Thisoften leads exasperated viewers to exclaim--is this really art?In this invaluable primer on aesthetics, Freeland explains why innovation and controversy are so highly valued in art, weaving together philosophy and art theory with many engrossing examples. Writing clearly and perceptively, she explores the cultural meanings of art in different contexts, and highlights the continuities of tradition that stretch from modern, often sensational, works back to the ancient halls of the Parthenon, to the medieval cathedral of Chartres, and to African nkisi nkondi fetish statues. She explores the difficulties of interpretation, examines recent scientific research into the ways the brain perceives art, and looks to the still-emerging worlds of art on the web, video art, art museum CD-ROMS, and much more. In addition, Freeland guides us through the various theorists of art, from Aristotle and Kant to Baudrillard. Lastly, throughout this nuanced account of theories, artists, and works, Freeland provides us with a rich understanding of how cultural significance is captured in a physical medium, and why challenging our perceptions is, and always has been, central to the whole endeavor.It is instructive to recall that Henri Matisse himself was originally derided as a "wild beast." To horrified critics, his bold colors and distorted forms were outrageous. A century later, what was once shocking is now considered beautiful. And that, writes Freeland, is art.

    This change is being driven by powerful new cognitive tools, enabled by the internet, which are greatly accelerating scientific discovery. There are many books about how the internet is changing business or the workplace or government. But this is the first book about something much more fundamental: how the internet is transforming the nature of our collective intelligence and how we understand the world.Reinventing Discovery tells the exciting story of an unprecedented new era of networked science. We learn, for example, how mathematicians in the Polymath Project are spontaneously coming together to collaborate online, tackling and rapidly demolishing previously unsolved problems. We learn how 250,000 amateur astronomers are working together in a project called Galaxy Zoo to understand the large-scale structure of the Universe, and how they are making astonishing discoveries, including an entirely new kind of galaxy. These efforts are just a small part of the larger story told in this book--the story of how scientists are using the internet to dramatically expand our problem-solving ability and increase our combined brainpower.This is a book for anyone who wants to understand how the online world is revolutionizing scientific discovery today--and why the revolution is just beginning.

    This long-awaited revision contains changes throughout the text. There are new implementations of most of the major programming systems in the book, including the interpreters and compilers, and the authors have incorporated many small changes that reflect their experience teaching the course at MIT since the first edition was published. A new theme has been introduced that emphasizes the central role played by different approaches to dealing with time in computational models: objects with state, concurrent programming, functional programming and lazy evaluation, and nondeterministic programming. There are new example sections on higher-order procedures in graphics and on applications of stream processing in numerical programming, and many new exercises. In addition, all the programs have been reworked to run in any Scheme implementation that adheres to the IEEE standard.
