Readers of earlier works by Douglas Hofstadter will find this book a natural extension of his style and his ideas about creativity and analogy; in addition, psychologists, philosophers, and artificial-intelligence researchers will find in this elaborate web of ingenious ideas a deep and challenging new view of mind.

    Unlike other texts, it begins with a detailed picture of the atom then builds toward chemistry's frontier, continually demonstrating how to solve problems, think about nature and matter, and visualize chemical concepts in the same ways as working chemists. The new edition incorporates features that extend the book's emphasis on modern techniques and applications while strengthening its problem solving approach. Atkins/Jones is the only book for this course featuring integrated book specific media that provides students with effective study help via a variety of electronic tools. The website at http: //www.whfreeman.com/chemicalprinciples3e has been developed simultaneously with the text and offers a range of tools for problem solving and chemical exploration

    In it, Russell offers a nontechnical, undogmatic account of his philosophical criticism as it relates to arithmetic and logic. Rather than an exhaustive treatment, however, the influential philosopher and mathematician focuses on certain issues of mathematical logic that, to his mind, invalidated much traditional and contemporary philosophy.In dealing with such topics as number, order, relations, limits and continuity, propositional functions, descriptions, and classes, Russell writes in a clear, accessible manner, requiring neither a knowledge of mathematics nor an aptitude for mathematical symbolism. The result is a thought-provoking excursion into the fascinating realm where mathematics and philosophy meet — a philosophical classic that will be welcomed by any thinking person interested in this crucial area of modern thought.

    From the #1 bestselling author of The Hot Zone comes an amazing account of scientific and spiritual passion for the tallest trees in the world, the startling biosystem of Rthe canopy, S and those who are committed to the preservation of this astonishing and largely unknown world.

    To its adherents, it is an elegant statement about learning from experience. To its opponents, it is subjectivity run amok.In the first-ever account of Bayes' rule for general readers, Sharon Bertsch McGrayne explores this controversial theorem and the human obsessions surrounding it. She traces its discovery by an amateur mathematician in the 1740s through its development into roughly its modern form by French scientist Pierre Simon Laplace. She reveals why respected statisticians rendered it professionally taboo for 150 years—at the same time that practitioners relied on it to solve crises involving great uncertainty and scanty information (Alan Turing's role in breaking Germany's Enigma code during World War II), and explains how the advent of off-the-shelf computer technology in the 1980s proved to be a game-changer. Today, Bayes' rule is used everywhere from DNA de-coding to Homeland Security.Drawing on primary source material and interviews with statisticians and other scientists, The Theory That Would Not Die is the riveting account of how a seemingly simple theorem ignited one of the greatest controversies of all time.

    The sea surrounds us. It gives us life, provides us with the air we breathe and the food we eat. It is ceaseless change and constant presence. It covers two-thirds of our planet. Yet caught up in our everyday lives, we barely notice it. In The Sea Inside, Philip Hoare sets out to rediscover the sea, its islands, birds and beasts. He begins on the south coast where he grew up, a place of almost monastic escape. From there he travels to the other side of the world - the Azores, Sri Lanka, New Zealand - in search of encounters with animals and people. Navigating between human and natural history, he asks what these stories mean for us now. Along the way we meet an amazing cast; from scientists to tattooed warriors; from ravens to whales and bizarre creatures that may, or may not, be extinct. Part memoir, part fantastical travelogue, The Sea Inside takes us on an astounding journey of discovery.

    They unearthed a treasure trove of Cretaceous dinosaurs and mammals, including several new species, that has already helped to reshape our understanding of the dinosaur age. In Dinosaurs of the Flaming Cliffs, team leader Michael Novacek, Provost of Science of the American Museum of Natural History and Curator of Vertebrate Paleontology, re-creates the day-to-day drama of field exploration over the past six years in the Gobi and recounts his and his colleagues' historic discoveries, reported in front-page headlines across the world. In a remarkable narrative that interweaves expedition chapters with in-depth scientific discussions on the nature and importance of the fossil record, Novacek takes us on a journey that explores the very nature of scientific inquiry and dinosaur research.

    He was also a memoirist who wrote with honesty and humor about the remarkable and strange encounters and experiences that shaped him (Uncle Tungsten, On the Move, Gratitude). Sacks, an Oxford-educated polymath, had a deep familiarity not only with literature and medicine but with botany, animal anatomy, chemistry, the history of science, philosophy, and psychology. The River of Consciousness is one of two books Sacks was working on up to his death, and it reveals his ability to make unexpected connections, his sheer joy in knowledge, and his unceasing, timeless project to understand what makes us human.

    Now a group of brave scientists are working to understand the actual conditions that cause eruptions, how to predict them, and what we can do, if anything, to temper their destructiveness. Thompson, a Time magazine correspondent, takes us from the May 1980 eruption of Mt. St. Helens in Washington state through new concentrated efforts to construct a wider-reaching and more rigid discipline.Thompson spent many hours with the relative handful of scientists whom he calls "volcano cowboys." They have loaned him their field notes and shared personal stories. That vivid material combined with Thompson's ability to bring a good story to life has resulted in a book that celebrates these "cowboys," their hazardous lives, and the often harrowing decisions they must make.

    As he did so masterfully in Prime Obsession, Derbyshire brings the evolution of mathematical thinking to dramatic life by focusing on the key historical players. Unknown Quantity begins in the time of Abraham and Isaac and moves from Abel's proof to the higher levels of abstraction developed by Galois through modern-day advances. Derbyshire explains how a simple turn of thought from this plus this equals this to this plus what equals this? gave birth to a whole new way of perceiving the world. With a historian's narrative authority and a beloved teacher's clarity and passion, Derbyshire leads readers on an intellectually satisfying and pleasantly challenging historical and mathematical journey.

    Coated in red dust, the terrain is bewilderingly empty. And yet multiple spacecraft are circling Mars, sweeping over Terra Sabaea, Syrtis Major, the dunes of Elysium, and Mare Sirenum—on the brink, perhaps, of a staggering find, one that would inspire humankind as much as any discovery in the history of modern science.In this beautifully observed, deeply personal book, Georgetown scientist Sarah Stewart Johnson tells the story of how she and other researchers have scoured Mars for signs of life, transforming the planet from a distant point of light into a world of its own.Johnson’s fascination with Mars began as a child in Kentucky, turning over rocks with her father and looking at planets in the night sky. She now conducts fieldwork in some of Earth’s most hostile environments, such as the Dry Valleys of Antarctica and the salt flats of Western Australia, developing methods for detecting life on other worlds. Here, with poetic precision, she interlaces her own personal journey—as a female scientist and a mother—with tales of other seekers, from Percival Lowell, who was convinced that a utopian society existed on Mars, to Audouin Dollfus, who tried to carry out astronomical observations from a stratospheric balloon. In the process, she shows how the story of Mars is also a story about Earth: This other world has been our mirror, our foil, a telltale reflection of our own anxieties and yearnings.Empathetic and evocative, The Sirens of Mars offers an unlikely natural history of a place where no human has ever set foot, while providing a vivid portrait of our quest to defy our isolation in the cosmos.

    Lured by the promise of riches, thousands of settlers left behind the forests, rain, and fertile soil of the eastern United States in favor of the rough-hewn lands of the American West. The dramatic terrain they struggled to cross is so familiar to us now that it is hard to imagine how frightening—even godforsaken—its sheer rock faces and barren deserts seemed to our forebears.        Hard Road West brings their perspective vividly to life, weaving together the epic overland journey of the covered wagon trains and the compelling story of the landscape they encountered. Taking readers along the 2,000-mile California Trail, Keith Meldahl uses the diaries and letters of the settlers themselves—as well as the countless hours he has spent following the trail—to reveal how the geology and geography of the West directly affected our nation’s westward expansion. He guides us through a corrugated landscape of sawtooth mountains, following the meager streams that served as lifelines through an arid land, all the way to California itself, where colliding tectonic plates created breathtaking scenery and planted the gold that lured travelers west in the first place. “Alternates seamlessly between vivid accounts of the 19th-century journey and lucid explanations of the geological events that shaped the landscape traveled. . . . The reader comes away with both an appreciation for the arduous cross-continental wagon journey and an understanding of the events that created such a vast and difficult landscape.”—Library Journal “[Meldahl] draws on his professional knowledge to explain the geology of the West, showing how centuries of geological activity had a direct effect on the routes taken by the travelers. . . . Meldahl provides a novel account of the largest overland migration since the Crusades.”—Science News

    Wallace, a contemporary of Charles Darwin, spent nearly a decade cataloging the plant and animal species which inhabited the unique geographical area of the Malay Archipelago, and remains to this day one of the most extensive works of natural history ever written.

    She conjures up early operating theaters--no place for the squeamish--and surgeons, working before anesthesia, who were lauded for their speed and brute strength. These medical pioneers knew that the aftermath of surgery was often more dangerous than their patients' afflictions, and they were baffled by the persistent infections that kept mortality rates stubbornly high. At a time when surgery couldn't have been more hazardous, an unlikely figure stepped forward: a young, melancholy Quaker surgeon named Joseph Lister, who would solve the deadly riddle and change the course of history.Fitzharris dramatically recounts Lister's discoveries in gripping detail, culminating in his audacious claim that germs were the source of all infection--and could be countered by antiseptics. Focusing on the tumultuous period from 1850 to 1875, she introduces us to Lister and his contemporaries--some of them brilliant, some outright criminal--and takes us through the grimy medical schools and dreary hospitals where they learned their art, the deadhouses where they studied anatomy, and the graveyards they occasionally ransacked for cadavers.Eerie and illuminating, The Butchering Art celebrates the triumph of a visionary surgeon whose quest to unite science and medicine delivered us into the modern world.

    Yet they remain among the most mysterious of concepts. Is space an entity? Why does time have a direction? Could the universe exist without space and time? Can we travel to the past? Greene has set himself a daunting task: to explain non-intuitive, mathematical concepts like String Theory, the Heisenberg Uncertainty Principle, and Inflationary Cosmology with analogies drawn from common experience. From Newton’s unchanging realm in which space and time are absolute, to Einstein’s fluid conception of spacetime, to quantum mechanics’ entangled arena where vastly distant objects can instantaneously coordinate their behavior, Greene takes us all, regardless of our scientific backgrounds, on an irresistible and revelatory journey to the new layers of reality that modern physics has discovered lying just beneath the surface of our everyday world.
