Each chapter of the book investigates a facet of the physical world, including the drag on small projectiles; the importance of diffusion and convection; the size-dependence of acceleration; the storage, conduction, and dissipation of heat; the relationship among pressure, flow, and choice in biological pumps; and how elongate structures tune their relative twistiness and bendiness. Vogel considers design-determining factors all too commonly ignored, and builds a bridge between the world described by physics books and the reality experienced by all creatures. Glimpses of Creatures in Their Physical Worlds contains a wealth of accessible information related to functional biology, and requires little more than a basic background in secondary-school science and mathematics.
Drawing examples from creatures of land, air, and water, the book demonstrates the many uses of biological diversity and how physical forces impact biological organisms.
This text provides an up-to-date overview of how animals run, walk, jump, crawl, swim, soar, hover, and fly. Excluding only the tiny creatures that use cilia, it covers all animals that power their movements with muscle--from roundworms to whales, clams to elephants, and gnats to albatrosses. The introduction sets out the general rules governing all modes of animal locomotion and considers the performance criteria--such as speed, endurance, and economy--that have shaped their selection. It introduces energetics and optimality as basic principles. The text then tackles each of the major modes by which animals move on land, in water, and through air. It explains the mechanisms involved and the physical and biological forces shaping those mechanisms, paying particular attention to energy costs.
Focusing on general principles but extensively discussing a wide variety of individual cases, this is a superb synthesis of current knowledge about animal locomotion. It will be enormously useful to advanced undergraduates, graduate students, and a range of professional biologists, physicists, and engineers.
The book begins with an overview of insect flight biomechanics. Dudley explains insect morphology, wing motions, aerodynamics, flight energetics, and flight metabolism within a modern phylogenetic setting. Drawing on biomechanical principles, he describes and evaluates flight behavior and the limits to flight performance. The author then takes the next step by developing evolutionary explanations of insect flight. He analyzes the origins of flight in insects, the roles of natural and sexual selection in determining how insects fly, and the relationship between flight and insect size, pollination, predation, dispersal, and migration. Dudley ranges widely--from basic aerodynamics to muscle physiology and swarming behavior--but his focus is the explanation of functional design from evolutionary and ecological perspectives.
The importance of flight in the lives of insects has long been recognized but never systematically evaluated. This book addresses that shortcoming. Robert Dudley provides an introduction to insect flight that will be welcomed by students and researchers in biomechanics, entomology, evolution, ecology, and behavior.
Watch a Fox News segment on The Longevity Project.
This landmark study--which Dr. Andrew Weil calls "a remarkable achievement with surprising conclusions"--upends the advice we have been told about how to live to a healthy old age.
We have been told that the key to longevity involves obsessing over what we eat, how much we stress, and how fast we run. Based on the most extensive study of longevity ever conducted, The Longevity Project exposes what really impacts our lifespan-including friends, family, personality, and work.
Gathering new information and using modern statistics to study participants across eight decades, Dr. Howard Friedman and Dr. Leslie Martin bust myths about achieving health and long life. For example, people do not die from working long hours at a challenging job- many who worked the hardest lived the longest. Getting and staying married is not the magic ticket to long life, especially if you're a woman. And it's not the happy-go-lucky ones who thrive-it's the prudent and persistent who flourish through the years.
With questionnaires that help you determine where you are heading on the longevity spectrum and advice about how to stay healthy, this book changes the conversation about living a long, healthy life.
Environmentalism, in theory and practice, is concerned with protecting nature. But if we have now reached “the end of nature,” as Bill McKibben and other environmental thinkers have declared, what is there left to protect? In Thinking like a Mall, Steven Vogel argues that environmental thinking would be better off if it dropped the concept of “nature” altogether and spoke instead of the “environment”—that is, the world that actually surrounds us, which is always a built world, the only one that we inhabit. We need to think not so much like a mountain (as Aldo Leopold urged) as like a mall. Shopping malls, too, are part of the environment and deserve as much serious consideration from environmental thinkers as do mountains.
Vogel argues provocatively that environmental philosophy, in its ethics, should no longer draw a distinction between the natural and the artificial and, in its politics, should abandon the idea that something beyond human practices (such as “nature”) can serve as a standard determining what those practices ought to be. The appeal to nature distinct from the built environment, he contends, may be not merely unhelpful to environmental thinking but in itself harmful to that thinking. The question for environmental philosophy is not “how can we save nature?” but rather “what environment should we inhabit, and what practices should we engage in to help build it?”

Despite the important interrelationship in archery between the anatomy of the human body and the anatomy of the bow, no book on the subject has previously been published. ARCHERY ANATOMY will therefore be an important and unique primer for coaches and performers alike. Detailed drawings combined with explanatory text explain how the skeleton and muscles should be used to improve performance in the most natural way, without artificial or strained movements. The book will stimulate analysis and understanding of the sport and, since it is not tied to any national or international rules, it will be useful to archers throughout the world, regardless of what discipline is practised. Coming at a time when sports science is becoming an essential qualification for all coaches, it is likely to be recognised as the standard work on the subject.
Deep brain stimulation has dramatically changed the lives of many patients with uncontrollable tremors. Patients often can resume normal activities, such as feeding and dressing themselves, and can have active and fulfilling lives. The need for anti-tremor medications is often reduced or eliminated.
Though it's no longer considered experimental, DBS is, for now, still used as a second- or third-line treatment, reserved for patients with more advanced cases of the disease and those for whom medication alone is inadequate or can't be adjusted precisely enough to keep their tremors and writhing under control.
However the idea of this surgery being a "last resort" is an evolving concept. Ten years ago doctors were operating on only the most severe, disabled, wheelchair-dependent patients, now they are operating on patients with moderate-to-severe cases of PD, ET and Dystonia. The thought is that this trend will continue. Instead of saying "wait another five to ten years until you become more disabled" doctors are realizing that the earlier they use DBS, the more they can improve the quality of life of their patients.
