Like the first edition, Dr. Allen presents the material in an engaging, accessible manner, with many historic insights and thorough explanations of attending concepts. The text retains its coverage of classical mechanics, essentially Newtonian mechanics, and adds chapters on three additional topics that go well beyond classical mechanics: relativity, quantum/nanomechanics, and biomechanics.

How Medicine Works and When It Doesn't: Learning Who to Trust to Get and Stay Healthy

by F. Perry Wilson

Blending personal anecdotes with hard science, an accomplished physician, researcher, and science communicator gives you the tools to avoid medical misinformation and take control of your health​: "A brilliant step toward patients and physicians alike reclaiming a sense of confidence in a system that often feels overwhelming and mismanaged" (Gabby Bernstein, #1 New York Times bestselling author of The Universe Has Your Back). We live in an age of medical miracles. Never in the history of humankind has so much talent and energy been harnessed to cure disease. So why does it feel like it&’s getting harder to live our healthiest lives? Why does it seem like &“experts&” can&’t agree on anything, and why do our interactions with medical professionals feel less personal, less honest, and less impactful than ever? Through stories from his own practice and historical case studies, Dr. F. Perry Wilson, a physician and researcher from the Yale School of Medicine, explains how and why the doctor-patient relationship has eroded in recent years and illuminates how profit-driven companies—from big Pharma to healthcare corporations—have corrupted what should have been medicine&’s golden age. By clarifying the realities of the medical field today, Dr. Wilson gives readers the tools they need to make informed decisions, from evaluating the validity of medical information online to helping caregivers advocate for their loved ones, in the doctor&’s office and with the insurance company. Dr. Wilson wants readers to understand medicine and medical science the way he does: as an imperfect and often frustrating field, but still the best option for getting well. To restore trust between patients, doctors, medicine, and science, we need to be honest, we need to know how to spot misinformation, and we need to avoid letting skepticism ferment into cynicism. For it is only by redefining what &“good medicine&” is—science that is well-researched, rational, safe, effective, and delivered with compassion, empathy, and trust—that the doctor-patient relationship can be truly healed.

How Men Age: What Evolution Reveals about Male Health and Mortality

by Richard G. Bribiescas

While the health of aging men has been a focus of biomedical research for years, evolutionary biology has not been part of the conversation--until now. How Men Age is the first book to explore how natural selection has shaped male aging, how evolutionary theory can inform our understanding of male health and well-being, and how older men may have contributed to the evolution of some of the very traits that make us human.In this informative and entertaining book, renowned biological anthropologist Richard Bribiescas looks at all aspects of male aging through an evolutionary lens. He describes how the challenges males faced in their evolutionary past influenced how they age today, and shows how this unique evolutionary history helps explain common aspects of male aging such as prostate disease, loss of muscle mass, changes in testosterone levels, increases in fat, erectile dysfunction, baldness, and shorter life spans than women. Bribiescas reveals how many of the physical and behavioral changes that we negatively associate with male aging may have actually facilitated the emergence of positive traits that have helped make humans so successful as a species, including parenting, long life spans, and high fertility.Popular science at its most compelling, How Men Age provides new perspectives on the aging process in men and how we became human, and also explores future challenges for human evolution--and the important role older men might play in them.

How Modernity Forgets

by Paul Connerton

Why are we sometimes unable to remember events, places and objects? This concise overview explores the concept of 'forgetting', and how modern society affects our ability to remember things. It takes ideas from Francis Yates classic work, 'The Art of Memory', which viewed memory as being dependent on stability, and argues that today's world is full of change, making 'forgetting' characteristic of contemporary society. We live our lives at great speed; cities have become so enormous that they are unmemorable; consumerism has become disconnected from the labour process; urban architecture has a short life-span; and social relationships are less clearly defined- all of which has eroded the foundations on which we build and share our memories. Providing a profound insight into the effects of modern society, this book is a must-read for anthropologists, sociologists, psychologists and philosophers, as well as anyone interested in social theory and the contemporary western world.

How Molecular Forces and Rotating Planets Create Life: The Emergence and Evolution of Prokaryotic Cells (Vienna Series in Theoretical Biology)

by Jan Spitzer

A reconceptualization of origins research that exploits a modern understanding of non-covalent molecular forces that stabilize living prokaryotic cells.Scientific research into the origins of life remains exploratory and speculative. Science has no definitive answer to the biggest questions--"What is life?" and "How did life begin on earth?" In this book, Jan Spitzer reconceptualizes origins research by exploiting a modern understanding of non-covalent molecular forces and covalent bond formation--a physicochemical approach propounded originally by Linus Pauling and Max Delbrück. Spitzer develops the Pauling-Delbrück premise as a physicochemical jigsaw puzzle that identifies key stages in life's emergence, from the formation of first oceans, tidal sediments, and proto-biofilms to progenotes, proto-cells and the first cellular organisms.

How Monkeys See the World: Inside the Mind of Another Species

by Robert M. Seyfarth Dorothy L. Cheney

Cheney and Seyfarth enter the minds of vervet monkeys and other primates to explore the nature of primate intelligence and the evolution of cognition. "This reviewer had to be restrained from stopping people in the street to urge them to read it: They would learn something of the way science is done, something about how monkeys see their world, and something about themselves, the mental models they inhabit."—Roger Lewin, Washington Post Book World "A fascinating intellectual odyssey and a superb summary of where science stands."—Geoffrey Cowley, Newsweek "A once-in-the-history-of-science enterprise."—Duane M. Rumbaugh, Quarterly Review of Biology

How Much Inequality Is Fair?: Mathematical Principles of a Moral, Optimal, and Stable Capitalist Society

by Venkat Venkatasubramanian

Many in the United States feel that the nation’s current level of economic inequality is unfair and that capitalism is not working for 90% of the population. Yet some inequality is inevitable. The question is: What level of inequality is fair? Mainstream economics has offered little guidance on fairness and the ideal distribution of income. Political philosophy, meanwhile, has much to say about fairness yet relies on qualitative theories that cannot be verified by empirical data. To address inequality, we need to know what the goal is—and for this, we need a quantitative, testable theory of fairness for free-market capitalism.How Much Inequality Is Fair? synthesizes concepts from economics, political philosophy, game theory, information theory, statistical mechanics, and systems engineering into a mathematical framework for a fair free-market society. The key to this framework is the insight that maximizing fairness means maximizing entropy, which makes it possible to determine the fairest possible level of pay inequality. The framework therefore provides a moral justification for capitalism in mathematical terms. Venkat Venkatasubramanian also compares his theory’s predictions to actual inequality data from various countries—showing, for instance, that Scandinavia has near-ideal fairness, while the United States is markedly unfair—and discusses the theory’s implications for tax policy, social programs, and executive compensation.

How Much Is Enough?

How Music Works: A Physical Culture Theory

by Rolf Bader

How do we understand culture and shape its future? How do we cross the bridge between culture as ideas and feelings and physical, cultural objects, all this within the endless variety and complexity of modern and traditional societies? This book proposes a Physical Culture Theory, taking culture as a self-organizing impulse pattern of electric forces. Bridging the gap to consciousness, the Physical Culture Theory proposes that consciousness content, what we think, hear, feel, or see is also just this: spatio-temporal electric fields. Music is a perfect candidate to elaborate on such a Physical Culture Theory. Music is all three, musical instrument acoustics, music psychology, and music ethnology. They emerge into living musical systems like all life is self-organization. Therefore the Physical Culture Theory knows no split between nature and nurture, hard and soft sciences, brains and musical instruments. It formulates mathematically complex systems as Physical Models rather than Artificial Intelligence. It includes ethical rules for maintaining life and finds culture and arts to be Human Rights. Enlarging these ideas and mathematical methods into all fields of culture, ecology, economy, or the like will be the task for the next decades to come.

How Nations Succeed: Manufacturing, Trade, Industrial Policy, and Economic Development

by Murat A. Yülek

This book assesses developmental experience in different countries as well as British expansion following the industrial revolution from a developmental perspective. It explains why some nations are rich and others are poor, and discusses how manufacturing made economies flourish and spur economic development. It explains how today’s governments can design and implement industrial policy, and how they can determine economically strategic sectors to break out of Low and Middle Income Traps.Closely linked to global trade and (im)balances, industrialization was never an accident. Industrialization explains how some countries experience export-led growth and others import-led slowdowns. Many confuse industrialization with the construction of factory buildings rather than a capacity and skill building process through certain stages. Industrial policy helps countries advance through those stages. Explaining technical concepts in understandable terms, the book discusses the capacity and limits of the developmental state in industrialization and in general in economic development, demonstrating how picking-the-winner type focused industrial policy has worked in different countries. It also discusses how industrial policy and science, technology and innovation policies should be sequenced for best results.

How Nature Works: Complexity in Interdisciplinary Research and Applications

by Ivan Zelinka Ali Sanayei Otto E. Rössler Hector Zenil

This book is based on the outcome of the "2012 Interdisciplinary Symposium on Complex Systems" held at the island of Kos. The book consists of 12 selected papers of the symposium starting with a comprehensive overview and classification of complexity problems, continuing by chapters about complexity, its observation, modeling and its applications to solving various problems including real-life applications. More exactly, readers will have an encounter with the structural complexity of vortex flows, the use of chaotic dynamics within evolutionary algorithms, complexity in synthetic biology, types of complexity hidden inside evolutionary dynamics and possible controlling methods, complexity of rugged landscapes, and more. All selected papers represent innovative ideas, philosophical overviews and state-of-the-art discussions on aspects of complexity. The book will be useful as instructional material for senior undergraduate and entry-level graduate students in computer science, physics, applied mathematics and engineering-type work in the area of complexity. The book will also be valuable as a resource of knowledge for practitioners who want to apply complexity to solve real-life problems in their own challenging applications. The authors and editors hope that readers will be inspired to do their own experiments and simulations, based on information reported in this book, thereby moving beyond the scope of the book.

How Neighborhoods Make Us Sick: Restoring Health and Wellness to Our Communities

by Veronica Squires Breanna Lathrop

Our neighborhoods are literally making us sick. Buildings with mold trigger asthma and other respiratory conditions. Geographic lack of access to food and health care increases childhood mortality. Community violence traumatizes residents. Poverty, unemployment, inadequate housing, food insecurity, racial injustice, and oppression cause physical changes in the body, resulting in disease and death. But there is hope. Loving our neighbor includes creating social environments in which people can be healthy. While working in community redevelopment and treating uninsured families, Veronica Squires and Breanna Lathrop discovered that creating healthier neighborhoods requires a commitment to health equity. Jesus' ministry brought healing through dismantling systems of oppression and overturning social norms that prevented people from living healthy lives. We can do the same in our communities through addressing social determinants that facilitate healing in under-resourced neighborhoods. Everyone deserves the opportunity for good health. The decisions we make and actions we take can promote the health of our neighbors.

How Not to Study a Disease: The Story of Alzheimer's

by Karl Herrup

An authority on Alzheimer's disease offers a history of past failures and a roadmap that points us in a new direction in our journey to a cure.For decades, some of our best and brightest medical scientists have dedicated themselves to finding a cure for Alzheimer's disease. What happened? Where is the cure? The biggest breakthroughs occurred twenty-five years ago, with little progress since. In How Not to Study a Disease, neurobiologist Karl Herrup explains why the Alzheimer's discoveries of the 1990s didn't bear fruit and maps a direction for future research. Herrup describes the research, explains what's taking so long, and offers an approach for resetting future research.Herrup offers a unique insider's perspective, describing the red flags that science ignored in the rush to find a cure. He is unsparing in calling out the stubbornness, greed, and bad advice that has hamstrung the field, but his final message is a largely optimistic one. Herrup presents a new and sweeping vision of the field that includes a redefinition of the disease and a fresh conceptualization of aging and dementia that asks us to imagine the brain as a series of interconnected "neighborhoods." He calls for changes in virtually every aspect of the Alzheimer's disease research effort, from the drug development process, to the mechanisms of support for basic research, to the often-overlooked role of the scientific media, and more. With How Not to Study a Disease, Herrup provides a roadmap that points us in a new direction in our journey to a cure for Alzheimer's.

How Old Is the Universe?

by David A. Weintraub

How a great enigma of astronomy was solvedAstronomers have determined that our universe is 13.7 billion years old. How exactly did they come to this precise conclusion? How Old Is the Universe? tells the incredible story of how astronomers solved one of the most compelling mysteries in science and, along the way, introduces readers to fundamental concepts and cutting-edge advances in modern astronomy.The age of our universe poses a deceptively simple question, and its answer carries profound implications for science, religion, and philosophy. David Weintraub traces the centuries-old quest by astronomers to fathom the secrets of the nighttime sky. Describing the achievements of the visionaries whose discoveries collectively unveiled a fundamental mystery, he shows how many independent lines of inquiry and much painstakingly gathered evidence, when fitted together like pieces in a cosmic puzzle, led to the long-sought answer. Astronomers don't believe the universe is 13.7 billion years old—they know it. You will too after reading this book. By focusing on one of the most crucial questions about the universe and challenging readers to understand the answer, Weintraub familiarizes readers with the ideas and phenomena at the heart of modern astronomy, including red giants and white dwarfs, cepheid variable stars and supernovae, clusters of galaxies, gravitational lensing, dark matter, dark energy and the accelerating universe—and much more. Offering a unique historical approach to astronomy, How Old Is the Universe? sheds light on the inner workings of scientific inquiry and reveals how astronomers grapple with deep questions about the physical nature of our universe.
