A class trip to the beach becomes an underwater lesson about food chains when Arnold and Keesha are challenged to discover what a tuna fish sandwich and some smelly green pond scum have in common.

    Frizzle and friends team up to locate a "star", and in the process learn about the cooperative nature of animal social groups. Full color.

    In the 1970s, he sent two prize students, Tim Plowman and Wade Davis, to follow in his footsteps and unveil the botanical secrets of coca, the notorious source of cocaine, a sacred plant known to the Inca as the Divine Leaf of Immortality.A stunning account of adventure and discovery, betrayal and destruction, One River is a story of two generations of explorers drawn together by the transcendent knowledge of Indian peoples, the visionary realms of the shaman, and the extraordinary plants that sustain all life in a forest that once stood immense and inviolable.

    In other words, by all of us."--Dr. Bernie Siegel, author of Love, Medicine and MiraclesRule One for the neurologist in residence: "You ain't never the same when the air hits your brain." In this fascinating book, Dr. Frank Vertosick brings that fact to life through intimate portraits of patients and unsparing yet gripping descriptions of brain surgery.With insight, humor, and poignancy, Dr. Vertosick chronicles his remarkable evolution from naive young intern to world-class neurosurgeon, where he faced, among other challenges, a six week-old infant with a tumor in her brain, a young man struck down in his prime by paraplegia, and a minister with a .22 caliber bullet lodged in his skull. In candid detail, WHEN THE AIR HITS YOUR BRAIN illuminates both the mysteries of the mind and the realities of the operating room."Riveting."--Publishers Weekly

    Most know Richard Feynman for the hilarious anecdotes and exploits in his best-selling books Surely You're Joking, Mr. Feynman! and What DoYou Care What Other People Think? But not always obvious in those stories was his brilliance as a pure scientist—one of the century's greatest physicists. With this book and CD, we hear the voice of the great Feynman in all his ingenuity, insight, and acumen for argument. This breathtaking lecture—"The Motion of the Planets Around the Sun"—uses nothing more advanced than high-school geometry to explain why the planets orbit the sun elliptically rather than in perfect circles, and conclusively demonstrates the astonishing fact that has mystified and intrigued thinkers since Newton: Nature obeys mathematics. David and Judith Goodstein give us a beautifully written short memoir of life with Feynman, provide meticulous commentary on the lecture itself, and relate the exciting story of their effort to chase down one of Feynman's most original and scintillating lectures.

    And yet, disturbingly, in today's so-called information age, pseudoscience is burgeoning with stories of alien abduction, channeling past lives, and communal hallucinations commanding growing attention and respect. As Sagan demonstrates with lucid eloquence, the siren song of unreason is not just a cultural wrong turn but a dangerous plunge into darkness that threatens our most basic freedoms.

    When the Magic School Bus turns into a bat, the gang gets the inside story on this eerie yet fascinating creature of the night.

    It's also a book full of entertainment and wonders. In The Song of the Dodo, we follow Quammen's keen intellect through the ideas, theories, and experiments of prominent naturalists of the last two centuries. We trail after him as he travels the world, tracking the subject of island biogeography, which encompasses nothing less than the study of the origin and extinction of all species. Why is this island idea so important? Because islands are where species most commonly go extinct -- and because, as Quammen points out, we live in an age when all of Earth's landscapes are being chopped into island-like fragments by human activity. Through his eyes, we glimpse the nature of evolution and extinction, and in so doing come to understand the monumental diversity of our planet, and the importance of preserving its wild landscapes, animals, and plants. We also meet some fascinating human characters. By the book's end we are wiser, and more deeply concerned, but Quammen leaves us with a message of excitement and hope.

    Frizzle's class is having a hard time putting together a giant globe of the world. A piece is missing...an island so new it hasn't been discovered yet! Before they know it, the kids are beneath the oceans's surface, exploring an underwater volcano. Join the class as they learn about volcanoes.

    Frizzle's class is learning all about water. And when Wanda suggests they take a trip to Waterland, Ms Frizzle gets that funny look in her eyes. But instead of taking her class to the water theme park, she takes them on a seriously wet and wild ride - through the water cycle! Join the class as they evaporate, condense, rain, and make their way back to the ocean...only to evaporate all over again!

    Sipser's candid, crystal-clear style allows students at every level to understand and enjoy this field. His innovative "proof idea" sections explain profound concepts in plain English. The new edition incorporates many improvements students and professors have suggested over the years, and offers updated, classroom-tested problem sets at the end of each chapter.

    Detailed descriptions and color photographs for over 100 species are provided, as well as an exploration of their long-standing (and often religious) use by ancient peoples and their continued significance to modern-day culture. Some of the species included have just been discovered in the past year or two, and still others have never before been photographed in their natural habitats.

    

    Now, in The Web of Life, he takes yet another giant step forward, offering a brilliant synthesis of such recent scientific breakthroughs as the theory of complexity, Gaia theory, and chaos theory. 25 line drawings.

    Frizzle's class is building a wonderful diorama of the desert, but learning about such a harsh environment has gotten Phoebe worried. What happens to all the animals in the desert without any water to sustain them in the scorching heat? Ties in with the PBS-TV series beginning in October 1995. Full color.

    Wilson has scrutinized animals in their natural settings, tweezing out the dynamics of their social organization, their relationship with their environments, and their behavior, not only for what it tells us about the animals themselves, but for what it can tell us about human nature and our own behavior. He has brought the fascinating and sometimes surprising results of these studies to general readers through a remarkable collection of books, including The Diversity of Life, The Ants, On Human Nature, and Sociobiology. The grace and precision with which he writes of seemingly complex topics has earned him two Pulitzer prizes, and the admiration of scientists and general readers around the world.In Search of Nature presents for the first time a collection of the seminal short writings of Edward O. Wilson, addressing in brief and eminently readable form the themes that have actively engaged this remarkable intellect throughout his career.""The central theme of the essays is that wild nature and human nature are closely interwoven. I argue that the only way to make complete sense of either is by examining both closely and together as products of evolution.... Human behavior is seen not just as the product of recorded history, ten thousand years recent, but of deep history, the combined genetic and cultural changes that created humanity over hundreds of thousands of years. We need this longer view, I believe, not only to understand our species, but more firmly to secure its future.The book is composed of three sections. ""Animal Nature, Human Nature"" ranges from serpents to sharks to sociality in ants. It asks how and why the universal aversion to snakes might have evolved in humans and primates, marvels at the diversity of the world's 350 species of shark and how their adaptive success has affected our conception of the world, and admonishes us to ""be careful of little lives""-to see in the construction of insect social systems ""another grand experiment in evolution for our delectation.""The Patterns of Nature"" probes at the foundation of sociobiology, asking what is the underlying genetic basis of social behavior, and what that means for the future of the human species. Beginning with altruism and aggression, the two poles of behavior, these essays describe how science, like art, adds new information to the accumulated wisdom, establishing new patterns of explanation and inquiry. In ""The Bird of Paradise: The Hunter and the Poet,"" the analytic and synthetic impulses-exemplified in the sciences and the humanities-are called upon to give full definition to the human prospect.""Nature's Abundance"" celebrates biodiversity, explaining its fundamental importance to the continued existence of humanity. From ""The Little Things That Run the World""-invertebrate species that make life possible for everyone and everything else-to the emergent belief of many scientists in the human species' possible innate affinity for other living things, known as biophilia, Wilson sets forth clear and compelling reasons why humans should concern themselves with species loss. ""Is Humanity Suicidal?"" compares the environmentalist's view with that of the exemptionalist, who holds that since humankind is transcendent in intelligence and spirit, our species must have been released from the iron laws of ecology that bind all other species. Not without optimism, Wilson concludes that we are smart enough and have time enough to avoid an environmental catastrophe of civilization-threatening dimensions-if we are willing both to redirect our science and technology and to reconsider our self-image as a species.In Search of Nature is a lively and accessible introduction to the writings of one of the most brilliant scientists of the 20th century. Imaginatively illustrated by noted artist Laura Southworth, it is a book all readers will treasure."

    Taken literally, it implies that there are many universes “parallel” to the one we see around us. This multiplicity of universes, according to Deutsch, turns out to be the key to achieving a new worldview, one which synthesizes the theories of evolution, computation, and knowledge with quantum physics. Considered jointly, these four strands of explanation reveal a unified fabric of reality that is both objective and comprehensible, the subject of this daring, challenging book. The Fabric of Reality explains and connects many topics at the leading edge of current research and thinking, such as quantum computers (which work by effectively collaborating with their counterparts in other universes), the physics of time travel, the comprehensibility of nature and the physical limits of virtual reality, the significance of human life, and the ultimate fate of the universe. Here, for scientist and layperson alike, for philosopher, science-fiction reader, biologist, and computer expert, is a startlingly complete and rational synthesis of disciplines, and a new, optimistic message about existence.

    What drives species to evolve? How can intricate structures such as the human eye, the spider's web or the wings of birds develop, seemingly by chance? Regarding evolution's most complex achievements as peaks on a metaphorical mountain, Climbing Mount Improbable reveals the ways in which the theory of natural selection can precisely explain the beautiful, bizarre and seemingly 'designed' complexity of living things.And through it all runs the thread of DNA, the molecule of life, responsible for its own destiny on an unending pilgrimage through time. Accompanied by evocative illustrations, Dawkins's eloquent descriptions of the living world's astonishing adaptations throw back the curtain on the mysteries of 'Mount Improbable'.An alternative cover edition for this ISBN can be found here.

    The Emotional Brain investigates the origins of human emotions and explains that many exist as part of complex neural systems that evolved to enable us to survive.

    Feynman gave his famous course on computation at the California Institute of Technology, he asked Tony Hey to adapt his lecture notes into a book. Although led by Feynman, the course also featured, as occasional guest speakers, some of the most brilliant men in science at that time, including Marvin Minsky, Charles Bennett, and John Hopfield. Although the lectures are now thirteen years old, most of the material is timeless and presents a “Feynmanesque” overview of many standard and some not-so-standard topics in computer science such as reversible logic gates and quantum computers.

    But was he right? Can the quantum theory of fields and Einstein's general theory of relativity, the two most accurate and successful theories in all of physics, be united in a single quantum theory of gravity? Can quantum and cosmos ever be combined? On this issue, two of the world's most famous physicists--Stephen Hawking ("A Brief History of Time") and Roger Penrose ("The Emperor's New Mind" and "Shadows of the Mind")--disagree. Here they explain their positions in a work based on six lectures with a final debate, all originally presented at the Isaac Newton Institute for Mathematical Sciences at the University of Cambridge.How could quantum gravity, a theory that could explain the earlier moments of the big bang and the physics of the enigmatic objects known as black holes, be constructed? Why does our patch of the universe look just as Einstein predicted, with no hint of quantum effects in sight? What strange quantum processes can cause black holes to evaporate, and what happens to all the information that they swallow? Why does time go forward, not backward?In this book, the two opponents touch on all these questions. Penrose, like Einstein, refuses to believe that quantum mechanics is a final theory. Hawking thinks otherwise, and argues that general relativity simply cannot account for how the universe began. Only a quantum theory of gravity, coupled with the no-boundary hypothesis, can ever hope to explain adequately what little we can observe about our universe. Penrose, playing the realist to Hawking's positivist, thinks that the universe is unbounded and will expand forever. The universe can be understood, he argues, in terms of the geometry of light cones, the compression and distortion of spacetime, and by the use of twistor theory. With the final debate, the reader will come to realize how much Hawking and Penrose diverge in their opinions of the ultimate quest to combine quantum mechanics and relativity, and how differently they have tried to comprehend the incomprehensible.

    They influence virtually all of the growing individual's characteristics, from determining its sex to controlling the numbers of toes and fingers to shaping intricate details of brain structure.Scientific research over the last 50 years has revealed that this hormonal control of development is vulnerable to disruption by synthetic chemicals. Through a variety of mechanisms, hormone-disrupting chemicals (also known as endocrine disrupting chemicals or endocrine disruptors) interfere with the natural messages and alter the course of development, with potential effects on virtually all aspects of bodily function.Our Stolen Future explores the scientific discovery of endocrine disruption. The investigation begins with wildlife, as it was in animals that the first hints of widespread endocrine disruption appeared. The book then examines a series of experiments examining endocrine disruption of animals in the laboratory which show conclusively that fetal exposure to endocrine disrupting chemicals can wreak life-long damage. These experiments also reveal some of the biological processes by which these chemicals have their effects, and that endocrine disruption effects can be caused by exposure to infinitesimally small amounts of contaminant. Moving from animals to people, Our Stolen Future summarizes a series of well-studied examples where people have been affected by endocrine disrupting chemicals, most notably the synthetic hormone dietheylstilbestrol (DES), to which several million women were exposed through misguided medical attempts to manage difficult pregnancies in the 1950s, '60s and '70s.Our Stolen Future then asks a broader, more difficult and more controversial set of questions. Given what is known from wildlife and laboratory studies, and from examples of well-studied human exposure, and given that exposure to endocrine disrupting chemicals in the real world is widespread at levels comparable to those sufficient to cause animal harm, what effects should health scientists be looking for in people in general? Effects to be expected include declines in fertility and other impacts on the reproductive system of both men and women, impairments in disease resistance, and erosions in intelligence.

    This discovery prompted a complete reevaluation of previous evidence for human origins.In the years since this dramatic discovery Johanson has continued to scour East Africa's Great rift Valley for the earliest evidence of human origins. In 1975 this team unearthed the "First Family", an unparalleled fossil assemblage of 13 individuals dating back to 3.2 million years ago; and in 1986 at the Rift's most famous location, Olduvai Gorge, this same team discovered a 1.8 million-year-old partial adult skeleton that necessitated a reassessment of the earliest members of our own genus Homo.Johanson's fieldwork continues unabated and recently more fossil members of Lucy's family have been found, including the 1992 discovery of the oldest, most complete skull of her species, with future research now planned for 1996 in the virtually unexplored regions of the most northern extension of the Rift Valley in Eritrea.From Lucy to Language is a summing up of this remarkable career and a stunning documentary of human life through time on Earth. It is a combination of the vital experience of field work and the intellectual rigor of primary research. It is the fusion of two great writing talents: Johanson and Blake Edgar, an accomplished science writer, editor of the California Academy of Sciences' Pacific Discovery, and co-author of Johanson's last book, Ancestors.From Lucy to Language is one of the greatest stories ever told, bracketing the timeline between bipedalism and human language. Part I addresses the central issues facing anyone seeking to decipher the mystery of human origins. In this section the authors provide answers to the basics -- "What are our closest living relatives?" -- tackle the controversial -- "What is race?" -- and contemplate the imponderables -- "Why did consciousness evolve?"From Lucy to Language is an encounter with the evidence. Early human fossils are hunted, discovered, identified, excavated, collected, preserved, labeled, cleaned, reconstructed, drawn, fondled, photographed, cast, compared, measured, revered, pondered, published, and argued over endlessly. Fossils like Lucy have become a talisman of sorts, promising to reveal the deepest secrets of our existence. In Part II the authors profile over fifty of the most significant early human fossils ever found. Each specimen is displayed in color and at actual size, most of them in multiple views. With them the authors present the cultural accoutrements associated with the fossils: stone tools which evidence increasing sophistication over time, the earliest stone, clay, and ivory art objects, and the culminating achievement of the dawn of human consciousness -- the magnificent rock and cave paintings of Europe, Africa, Australia, and the Americas.In the end From Lucy to Language is a reminder and a challenge. Like no species before us, we now seem poised to control vast parts of the planet and its life. We possess the power to influence, if not govern, evolution. For that reason, we must not forget our link to the natural world and our debt to natural selection. We need to "think deep", to add a dose of geologic time and evolutionary history to our perspective of who we are, where we came from, and where we are headed. This is the most poignant lesson this book has to offer.

    Created primarily for medical and premedical students, 'Neuroscience' emphasizes the structure of the nervous system, the correlation of structure and function, and the structure/function relationships particularly pertinent to the practice of medicine.

    It shows how human-engineered dams, canals and farms replaced nature's beaver dams, prairie dog tunnels, and buffalo wallows. Step by step, Outwater makes clear what should have always been obvious: while engineering can de-pollute water, only ecologically interacting systems can create healthy waterways. Important reading for students of environmental studies, the heart of this history is a vision of our land and waterways as they once were, and a plan that can restore them to their former glory: a land of living streams, public lands with hundreds of millions of beaver-built wetlands, prairie dog towns that increase the amount of rainfall that percolates to the groundwater, and forests that feed their fallen trees to the sea.

    Until now, most of these questions were addressed by religion and philosophy. But science has reached a point where it, too, can voice an opinion. Beginning with the Big Bang roughly fifteen billion years ago, the authors trace the evolution of the cosmos, from the first particles, the atoms, the molecules, the development of cells, organisms, and living creatures, up to the arrival of "Homo erectus" and "Homo sapiens." Proactive, informative, and free of technical or scientific jargon, "Origins" offers compelling insights into how the universe, life on Earth, and the human species began.

    Renowned scientist David Bohm believed there was a better way for humanity to discover meaning and to achieve harmony. He identified creative dialogue, a sharing of assumptions and understanding, as a means by which the individual, and society as a whole, can learn more about themselves and others, and achieve a renewed sense of purpose.

    As a pragmatic, hands-on guide for beginning to intermediate hobbyists, The Conscientious Marine Aquarist demystifies the process of planning, setting up, stocking, and managing a beautiful, thriving slice of the tropical ocean. A leading advocate for the responsible collection and care of wild-caught specimens, Fenner starts with the basics -- "What is a fish?" -- and proceeds to give the reader the scientific background and expert-level secrets to being a smarter consumer, better steward, and more successful marine aquarium keeper.

    By studying fish in streams and by closely observing the natural water cycle, Viktor Schauberger (1885-1958) was able to solve basic problems of energy transformation. He saw that modern man, without realizing it, was destroying the earth and sabotaging his own cultures by working against Nature. All the prevailing methods of energy generation - from hydro-electric to nuclear fission - produce harmful long-term effects on the environment and encourage disease. Schauberger had a clear vision of how fertility could be restored to the earth. As an inventor Schauberger developed a number of ingenious machines which would revolutionize farming, horticulture, forestry and aircraft propulsion. He developed water purification systems, and showed how air and water could be harnessed as fuels for many machines. His discovery of implosive energy and diamagnetism had many practical applications, most of which have yet to be developed.

    In terms of numbers, beetles are the most successful creatures on earth: about 350,000 species of beetles have been described since 1758. They range from tiny to gigantic, occupy sundry habitats, and eat everything--plants, animals, and their own remains. An Inordinate Fondness for Beetles provides an engaging look at these magnificent yet poorly understood creatures and highlights the absolutely essential role they play in the dynamics of nearly every terrestrial ecosystem on Earth. And, as this book beautifully demonstrates, the aesthetics of beetle design are amazing. The fantastic colors and shapes of these creatures warrant the gorgeous color photography lavished on them in this book.

    In this brilliant book, Henri Bortoft (who began his studies of Goethean science with J. G. Bennett and David Bohm) introduces the fascinating scientific theories of Goethe. He succeeds in showing that Goethe's way of doing science was not a poet's folly but a genuine alternative to the dominant scientific paradigm.Bortoft shows that a different, "gentler" kind of empiricism is possible than that demanded by the dualizing mind of modern technological science and demonstrates that Goethe's participatory phenomenology of a new way of seeing--while far from being a historical curiosity--in fact proposes a practical solution to the dilemmas of contemporary, postmodern science.If you read only one book on Goethan science, this should be the one!

    In this visionary book, noted planetary scientist John S. Lewis explains how we can mine these precious metals from the asteroids, comets, and planets in our own solar system for use in space construction projects. And this is just one of the possibilities. Join John S. Lewis as he contemplates milking the moons of Mars for water and hollowing out asteroids for space-bound homesteaders—all while demonstrating the economic and technical feasibility of plans that were once considered pure fiction.

    Braving the sexism of the scientific world, she joined the prestigious Kaiser Wilhelm Institute for Chemistry and became a prominent member of the international physics community. Of Jewish origin, Meitner fled Nazi Germany for Stockholm in 1938 and later moved to Cambridge, England. Her career was shattered when she fled Germany, and her scientific reputation was damaged when Hahn took full credit—and the 1944 Nobel Prize—for the work they had done together on nuclear fission. Ruth Sime's absorbing book is the definitive biography of Lise Meitner, the story of a brilliant woman whose extraordinary life illustrates not only the dramatic scientific progress but also the injustice and destruction that have marked the twentieth century.

    Many still vividly remember exactly where they were and what they were doing when they heard about the tragedy. In The Challenger Launch Decision, Diane Vaughan recreates the steps leading up to that fateful decision, contradicting conventional interpretations to prove that what occurred at NASA was not skulduggery or misconduct but a disastrous mistake.Journalists and investigators have historically cited production problems and managerial wrong-doing as the reasons behind the disaster. The Presidential Commission uncovered a flawed decision-making process at the space agency as well, citing a well-documented history of problems with the O-ring and a dramatic last-minute protest by engineers over the Solid Rocket Boosters as evidence of managerial neglect.Why did NASA managers, who not only had all the information prior to the launch but also were warned against it, decide to proceed? In retelling how the decision unfolded through the eyes of the managers and the engineers, Vaughan uncovers an incremental descent into poor judgment, supported by a culture of high-risk technology. She reveals how and why NASA insiders, when repeatedly faced with evidence that something was wrong, normalized the deviance so that it became acceptable to them.No safety rules were broken. No single individual was at fault. Instead, the cause of the disaster is a story not of evil but of the banality of organizational life. This powerful work explains why the Challenger tragedy must be reexamined and offers an unexpected warning about the hidden hazards of living in this technological age.

    The era covered by this book, 1950 to 1990, was surely one of the golden ages of science as well as the American university.Cherished myths are debunked along the way as Gian-Carlo Rota takes pleasure in portraying, warts and all, some of the great scientific personalities of the period Stanislav Ulam (who, together with Edward Teller, signed the patent application for the hydrogen bomb), Solomon Lefschetz (Chairman in the 50s of the Princeton mathematics department), William Feller (one of the founders of modern probability theory), Jack Schwartz (one of the founders of computer science), and many others.Rota is not afraid of controversy. Some readers may even consider these essays indiscreet. After the publication of the essay "The Pernicious Influence of Mathematics upon Philosophy" (reprinted six times in five languages) the author was blacklisted in analytical philosophy circles. Indiscrete Thoughts should become an instant classic and the subject of debate for decades to come."Read Indiscrete Thoughts for its account of the way we were and what we have become; for its sensible advice and its exuberant rhetoric."--The Mathematical Intelligencer"Learned, thought-provoking, politically incorrect, delighting in paradox, and likely to offend but everywhere readable and entertaining."--The American Mathematical Monthly"It is about mathematicians, the way they think, and the world in which the live. It is 260 pages of Rota calling it like he sees it... Readers are bound to find his observations amusing if not insightful. Gian-Carlo Rota has written the sort of book that few mathematicians could write. What will appeal immediately to anyone with an interest in research mathematics are the stories he tells about the practice of modern mathematics."--MAA Reviews"

    Might there he a code of ethics in the animal kingdom? Must an animal be human to he humane? In this provocative book, a renowned scientist takes on those who have declared ethics uniquely human Making a compelling case for a morality grounded in biology, he shows how ethical behavior is as much a matter of evolution as any other trait, in humans and animals alike.World famous for his brilliant descriptions of Machiavellian power plays among chimpanzees-the nastier side of animal life--Frans de Waal here contends that animals have a nice side as well. Making his case through vivid anecdotes drawn from his work with apes and monkeys and holstered by the intriguing, voluminous data from his and others' ongoing research, de Waal shows us that many of the building blocks of morality are natural: they can he observed in other animals. Through his eyes, we see how not just primates but all kinds of animals, from marine mammals to dogs, respond to social rules, help each other, share food, resolve conflict to mutual satisfaction, even develop a crude sense of justice and fairness.Natural selection may be harsh, but it has produced highly successful species that survive through cooperation and mutual assistance. De Waal identifies this paradox as the key to an evolutionary account of morality, and demonstrates that human morality could never have developed without the foundation of fellow feeling our species shares with other animals. As his work makes clear, a morality grounded in biology leads to an entirely different conception of what it means to he human--and humane.

Designed for use in introductory cell biology courses, The Cell presents current, comprehensive science in a readable and cohesive text that students can master in the course of one semester. The new third edition of The Cell retains the organization, themes, and special features of earlier editions, but is updated to reflect scientific advances since publication of the second edition, including progress in genome sequencing, advances in understanding transcriptional regulation and mRNA processing, use of DNA microarrays in global studies of gene expression and cancer diagnostics, advances in nuclear transport and protein trafficking, progress in understanding the regulation of programmed cell death, potential medical applications of embryonic cells, and development of oncogene-targeted treatments. Key Experimental boxes in each chapter describe seminal experiments in modern cell biology, showing the detail and background to give students a sense of doing science. Molecular Medicine boxes relate basic science to clinical practice or potential and show the excitement of molecular discovery and solutions to disease. Chapter summaries are organized in outline form corresponding to the major sections and subsections of each chapter. This section-by-section format is coupled with a list of the key terms introduced in eachsection, providing a succinct but comprehensive review of the material. The full-color art program is both pedagogically and scientifically outstanding. In addition, each chapter includes a brief chapter outline, boldfaced key terms (also defined in the glossary), and many new chapter-end questions with answers in the back of the book. With a clear focus on cell biology as an integrative theme, topics such as developmental biology, plant biology, the immune system, the nervous system, and muscle physiology are covered in their broader biological context. The book can be bundled for purchase with a special edition of Molecules, Cells, and Genes, a CD-ROM keyed to the textbook and combining the essential features of a Study Guide and Problems book.

    In treating cognition as problem solving, Andy Clark suggests, we may often abstract too far from the very body and world in which our brains evolved to guide us. Whereas the mental has been treated as a realm that is distinct from the body and the world, Clark forcefully attests that a key to understanding brains is to see them as controllers of embodied activity. From this paradigm shift he advances the construction of a cognitive science of the embodied mind.

    DO I REALLY HAVE TO CHOOSE BETWEEN RELIGION AND SCIENCE?In this ground-breaking work, Old Testament scholar John Sailhamer shines new light on the opening chapters of the Bible, revealing how centuries-old misunderstandings have continued to shape popular biblical interpretation — as well as greatly contributing to unnecessary conflicts between the Bible and science.Pointing to answers found in the first two chapters of Genesis, Sailhamer presents a credible, scripturally supported, and much-needed explanation that opens the door to reconciliation of biblical and scientific world views.No matter what your position or background, you will be challenged to test your understanding of the Bible’s critical opening sentences and reexamine your beliefs about the creation of the world through Genesis Unbound.

    Dennett, Gerald Edelman, and Roger Penrose, all firing volleys in what has come to be called the consciousness wars. Now, in The Conscious Mind, philosopher David J. Chalmers offers a cogent analysis of this heated debate as he unveils a major new theory of consciousness, one that rejects the prevailing reductionist trend of science, while offering provocative insights into the relationship between mind and brain.Writing in a rigorous, thought-provoking style, the author takes us on a far-reaching tour through the philosophical ramifications of consciousness. Chalmers convincingly reveals how contemporary cognitive science and neurobiology have failed to explain how and why mental events emerge from physiological occurrences in the brain. He proposes instead that conscious experience must be understood in an entirely new light--as an irreducible entity (similar to such physical properties as time, mass, and space) that exists at a fundamental level and cannot be understood as the sum of its parts. And after suggesting some intriguing possibilities about the structure and laws of conscious experience, he details how his unique reinterpretation of the mind could be the focus of a new science. Throughout the book, Chalmers provides fascinating thought experiments that trenchantly illustrate his ideas. For example, in exploring the notion that consciousness could be experienced by machines as well as humans, Chalmers asks us to imagine a thinking brain in which neurons are slowly replaced by silicon chips that precisely duplicate their functions--as the neurons are replaced, will consciousness gradually fade away? The book also features thoughtful discussions of how the author's theories might be practically applied to subjects as diverse as artificial intelligence and the interpretation of quantum mechanics.All of us have pondered the nature and meaning of consciousness. Engaging and penetrating, The Conscious Mind adds a fresh new perspective to the subject that is sure to spark debate about our understanding of the mind for years to come.

    This recreational math book takes the reader on a fantastic voyage into the world of natural numbers. From the earliest discoveries of the ancient Greeks to various fundamental characteristics of the natural number sequence, Clawson explains fascinating mathematical mysteries in clear and easy prose. He delves into the heart of number theory to see and understand the exquisite relationships among natural numbers, and ends by exploring the ultimate mystery of mathematics: the Riemann hypothesis, which says that through a point in a plane, no line can be drawn parallel to a given line.While a professional mathematician's treatment of number theory involves the most sophisticated analytical tools, its basic ideas are surprisingly easy to comprehend. By concentrating on the meaning behind various equations and proofs and avoiding technical refinements, Mathematical Mysteries lets the common reader catch a glimpse of this wonderful and exotic world.

    Protect a bacterium from predators, and provide it with adequate food and space to grow, and it would continue living--and reproducing asexually--forever. But a paramecium (a slightly more advanced single-cell organism), under the same ideal conditions, would stop dividing after about 200 generations--and die. Death, for paramecia and their offspring, is inevitable. Unless they have sex. If at any point during that 200 or so generations, two of the progeny of our paramecium have sex, their clock will be reset to zero. They and their progeny aregranted another 200 generations. Those who fail to have sex eventually die. Immortality for bacteria is automatic; for all other living beings--including humans--immortality depends on having sex. But why is this so? Why must death be inevitable? And what is the connection between death and sexualreproduction? In Sex and the Origins of Death, William R. Clark looks at life and death at the level of the cell, as he addresses such profound questions as why we age, why death exists, and why death and sex go hand in hand. Clark reveals that there are in fact two kinds of cell death--accidental death, caused by extreme cold or heat, starvation, or physical destruction, and programmed cell death, initiated by codes embedded in our DNA. (Bacteria have no such codes.) We learn that every cell in our body has a self-destruct program embedded into it and that cell suicide is in fact a fairlycommonplace event. We also discover that virtually every aspect of a cell's life is regulated by its DNA, including its own death, that the span of life is genetically determined (identical twins on average die 36 months apart, randomly selected siblings 106 months apart), that human tissue inculture will divide some 50 times and then die (an important exception being tumor cells, which divide indefinitely). But why do our cells have such programs? Why must we die? To shed light on this question, Clark reaches far back in evolutionary history, to the moment when inevitable death (deathfrom aging) first appeared. For cells during the first billion years, death, when it occurred, was accidental; there was nothing programmed into them that said they must die. But fierce competition gradually led to multicellular animals--size being an advantage against predators--and with thischange came cell specialization and, most important, germ cells in which reproductive DNA was segregated. When sexual reproduction evolved, it became the dominant form of reproduction on the planet, in part because mixing DNA from two individuals corrects errors that have crept into the code. Butthis improved DNA made DNA in the other (somatic) cells not only superfluous, but dangerous, because somatic DNA might harbor mutations. Nature's solution to this danger, Clark concludes, was programmed death--the somatic cells must die. Unfortunately, we are the somatic cells. Death is necessary toexploit to the fullest the advantages of sexual reproduction. In Sex and the Origins of Death, William Clark ranges far and wide over fascinating terrain. Whether describing a 62-year-old man having a major heart attack (and how his myocardial cells rupture and die), or discussing curious life-forms that defy any definition of life (including bacterialspores, which can regenerate after decades of inactivity, and viruses, which are nothing more than DNA or RNA wrapped in protein), this brilliant, profound volume illuminates the miraculous workings of life at its most elemental level and finds in these tiny spaces the answers to some of our largestquestion

    Steven Epstein's astute and readable investigation focuses on the critical question of "how certainty is constructed or deconstructed," leading us through the views of medical researchers, activists, policy makers, and others to discover how knowledge about AIDS emerges out of what he calls "credibility struggles."Epstein shows the extent to which AIDS research has been a social and political phenomenon and how the AIDS movement has transformed biomedical research practices through its capacity to garner credibility by novel strategies. Epstein finds that nonscientist AIDS activists have gained enough of a voice in the scientific world to shape NIH–sponsored research to a remarkable extent. Because of the blurring of roles and responsibilities, the production of biomedical knowledge about AIDS does not, he says, follow the pathways common to science; indeed, AIDS research can only be understood as a field that is unusually broad, public, and contested. He concludes by analyzing recent moves to democratize biomedicine, arguing that although AIDS activists have set the stage for new challenges to scientific authority, all social movements that seek to democratize expertise face unusual difficulties.Avoiding polemics and accusations, Epstein provides a benchmark account of the AIDS epidemic to date, one that will be as useful to activists, policy makers, and general readers as to sociologists, physicians, and scientists.

    These outcomes often may be highly constrained and universal, yet are not themselves directly contained in the genes in any domain-specific way.One of the key contributions of Rethinking Innateness is a taxonomy of ways in which a behavior can be innate. These include constraints at the level of representation, architecture, and timing; typically, behaviors arise through the interaction of constraints at several of these levels.The ideas are explored through dynamic models inspired by a new kind of developmental connectionism, a marriage of connectionist models and developmental neurobiology, forming a new theoretical framework for the study of behavioral development. While relying heavily on the conceptual and computational tools provided by connectionism, Rethinking Innateness also identifies ways in which these tools need to be enriched by closer attention to biology.

    The answers to these questions are then pursued in experiments on sensory neurons. Intended for neurobiologists with an interest in mathematical analysis of neural data as well as the growing number of physicists and mathematicians interested in information processing by real nervous systems, Spikes provides a self-contained review of relevant concepts in information theory and statistical decision theory.Our perception of the world is driven by input from the sensory nerves. This input arrives encoded as sequences of identical spikes. Much of neural computation involves processing these spike trains. What does it mean to say that a certain set of spikes is the right answer to a computational problem? In what sense does a spike train convey information about the sensory world? Spikes begins by providing precise formulations of these and related questions about the representation of sensory signals in neural spike trains. The answers to these questions are then pursued in experiments on sensory neurons.The authors invite the reader to play the role of a hypothetical observer inside the brain who makes decisions based on the incoming spike trains. Rather than asking how a neuron responds to a given stimulus, the authors ask how the brain could make inferences about an unknown stimulus from a given neural response. The flavor of some problems faced by the organism is captured by analyzing the way in which the observer can make a running reconstruction of the sensory stimulus as it evolves in time. These ideas are illustrated by examples from experiments on several biological systems.Intended for neurobiologists with an interest in mathematical analysis of neural data as well as the growing number of physicists and mathematicians interested in information processing by real nervous systems, Spikes provides a self-contained review of relevant concepts in information theory and statistical decision theory. A quantitative framework is used to pose precise questions about the structure of the neural code. These questions in turn influence both the design and analysis of experiments on sensory neurons.

    It describes and illustrates the results of more than fifteen years of elegant experimental studies conducted by the author. In his investigations, Thomas Seeley has sought the answer to the question of how a colony of bees is organized to gather its resources. The results of his research--including studies of the shaking signal, tremble dance, and waggle dance, and other, more subtle means by which information is exchanged among bees--offer the clearest, most detailed picture available of how a highly integrated animal society works. By showing how several thousand bees function together as an integrated whole to collect the nectar, pollen, and water that sustain the life of the hive, Seeley sheds light on one of the central puzzles of biology: how units at one level of organization can work together to form a higher-level entity.In explaining why a hive is organized the way it is, Seeley draws on the literature of molecular biology, cell biology, animal and human sociology, economics, and operations research. He compares the honey bee colony to other functionally organized groups: multicellular organisms, colonies of marine invertebrates, and human societies. All highly cooperative groups share basic problems: of allocating their members among tasks so that more urgent needs are met before less urgent ones, and of coordinating individual actions into a coherent whole. By comparing such systems in different species, Seeley argues, we can deepen our understanding of the mechanisms that make close cooperation a reality.

    While maintaining the hallmark features of previous editions, the Fourth Edition has been completely updated.

    On the way to showing how the world of our ancient ancestors shaped our modern modular mind, Steven Mithen shares one provocative insight after another as he answers a series of fascinating questions:Were our brains hard-wired in the Pleistocene Era by the needs of hunter-gatherers?When did religious beliefs first emerge?Why were the first paintings made by humankind so technically accomplished and expressive?What can the sexual habits of chimpanzees tell us about the prehistory of the modern mind?This is the first archaeological account to support the new modular concept of the mind. The concept, promulgated by cognitive and evolutionary psychologists, views the mind as a collection of specialized intelligences or "cognitive domains," somewhat like a Swiss army knife with its specialized blades and tools. Arguing that only archaeology can answer many of the key questions raised by the new concept, Mithen delineates a three-phase sequence for the mind's evolution over six million years—from early Homo in Africa to the ice-age Neanderthals to our modern modular minds. The Prehistory of the Mind is an intriguing and challenging explanation of what it means to be human, a bold new theory about the origins and nature of the mind.

    Computer simulators are continuously confronted with questions concerning the choice of a particular technique for a given application. A wide variety of tools exist, so the choice of technique requires a good understanding of the basic principles. More importantly, such understanding may greatly improve the efficiency of a simulation program. The implementation of simulation methods is illustrated in pseudocodes and their practical use in the case studies used in the text.Since the first edition only five years ago, the simulation world has changed significantly -- current techniques have matured and new ones have appeared. This new edition deals with these new developments; in particular, there are sections on:Transition path sampling and diffusive barrier crossing to simulaterare events Dissipative particle dynamic as a course-grained simulation technique Novel schemes to compute the long-ranged forces Hamiltonian and non-Hamiltonian dynamics in the context constant-temperature and constant-pressure molecular dynamics simulations Multiple-time step algorithms as an alternative for constraints Defects in solids The pruned-enriched Rosenbluth sampling, recoil-growth, and concerted rotations for complex molecules Parallel tempering for glassy HamiltoniansExamples are included that highlight current applications and the codes of case studies are available on the World Wide Web. Several new examples have been added since the first edition to illustrate recent applications. Questions are included in this new edition. No prior knowledge of computer simulation is assumed.

    Houseplants can perform these essential functions in your home or office with the same efficiency as a rainforest in our biosphere.In research designed to create a breathable environment for a NASA lunar habitat, noted scientist Dr. B.C. Wolverton discovered that houseplants are the best filters of common pollutants such as ammonia, formaldehyde, and benzene. Hundreds of these poisonous chemicals can be released by furniture, carpets, and building material, and then trapped by closed ventilation systems, leading to the host of respiratory and allergic reactions now called Sick Building Syndrome. In this full-color, easy-to-follow guide, Dr. Wolverton shows you how to grow and nurture 50 plants as accessible and trouble-free as the tulip and the Boston fern, and includes many beautiful but commonly found varieties not generally thought of as indoor plants. He also rates each plant for its effectiveness in removing pollutants, and its ease of growth and maintenance.Studies show that Americans spend ninety percent of their lives indoors, which means that good indoor air quality is vital for good health. How to Grow Fresh Air will show you how to purify the environment that has the most impact on you.--back cover
