How to Walk on Water and Climb up Walls


Book Description

Discovering the secrets of animal movement and what they can teach us Insects walk on water, snakes slither, and fish swim. Animals move with astounding grace, speed, and versatility: how do they do it, and what can we learn from them? In How to Walk on Water and Climb up Walls, David Hu takes readers on an accessible, wondrous journey into the world of animal motion. From basement labs at MIT to the rain forests of Panama, Hu shows how animals have adapted and evolved to traverse their environments, taking advantage of physical laws with results that are startling and ingenious. In turn, the latest discoveries about animal mechanics are inspiring scientists to invent robots and devices that move with similar elegance and efficiency. Hu follows scientists as they investigate a multitude of animal movements, from the undulations of sandfish and the way that dogs shake off water in fractions of a second to the seemingly crash-resistant characteristics of insect flight. Not limiting his exploration to individual organisms, Hu describes the ways animals enact swarm intelligence, such as when army ants cooperate and link their bodies to create bridges that span ravines. He also looks at what scientists learn from nature’s unexpected feats—such as snakes that fly, mosquitoes that survive rainstorms, and dead fish that swim upstream. As researchers better understand such issues as energy, flexibility, and water repellency in animal movement, they are applying this knowledge to the development of cutting-edge technology. Integrating biology, engineering, physics, and robotics, How to Walk on Water and Climb up Walls demystifies the remarkable mechanics behind animal locomotion.

Valley Walls


Book Description

Half a century ago a rag-tag group of innovators was building a foundation for modern American rock climbing from a makeshift home base in Yosemite. Photographer Glen Denny was a key figure in this golden age of climbing, capturing pioneering feats on camera while tackling challenging ascents himself. In entertaining short pieces enlivened by his iconic black-and-white images of Yosemite's big wall legends, Denny reveals a young man's coming of age and provides a vivid look at Yosemite’s early climbing culture. He relates such precarious achievements as hauling water in glass gallon jugs up the east face of Washington Column, nailing the 750-foot Rostrum in a punishing heat wave, and dangling overnight on El Capitan’s Dihedral Wall in a lightning storm. Each true tale captures the spirit of historic Camp 4, where Denny and others plan the next big climb while living on the cheap and dodging park rangers.




The Mechanical Adaptations of Bones


Book Description

This book relates the mechanical and structural properties of bone to its function in man and other vertebrates. John Currey, one of the pioneers of modern bone research, reviews existing information in the field and particularly emphasizes the correlation of the structure of bone with its various uses. Originally published in 1984. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press.

Neural Networks and Animal Behavior


Book Description

How can we make better sense of animal behavior by using what we know about the brain? This is the first book that attempts to answer this important question by applying neural network theory. Scientists create Artificial Neural Networks (ANNs) to make models of the brain. These networks mimic the architecture of a nervous system by connecting elementary neuron-like units into networks in which they stimulate or inhibit each other's activity in much the same way neurons do. This book shows how scientists can employ ANNs to analyze animal behavior, explore the general principles of the nervous systems, and test potential generalizations among species. The authors focus on simple neural networks to show how ANNs can be investigated by math and by computers. They demonstrate intuitive concepts that make the operation of neural networks more accessible to nonspecialists. The first chapter introduces various approaches to animal behavior and provides an informal introduction to neural networks, their history, and their potential advantages. The second chapter reviews artificial neural networks, including biological foundations, techniques, and applications. The following three chapters apply neural networks to such topics as learning and development, classical instrumental condition, and the role of genes in building brain networks. The book concludes by comparing neural networks to other approaches. It will appeal to students of animal behavior in many disciplines. It will also interest neurobiologists, cognitive scientists, and those from other fields who wish to learn more about animal behavior.

Michael Foster and the Cambridge School of Physiology


Book Description

Despite great ferment and activity among historians of science in recent years, the history of physiology after 1850 has received little attention. Gerald Geison makes an important contribution to our knowledge of this neglected area by investigating the achievements of English physiologists at the Cambridge School from 1870 to 1900. He describes individual scientists, their research, the scientific issues affecting their work, and socio-institutional influences on the group. He pays special attention to the personality and contributions of Michael Foster, founding father of the Cambridge School. Foster's specific research interest was the origin of the rhythmic heartbeat, and the author contends that the school itself descended from and developed around this concern. Originally published in 1978. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press.

The Humane Gardener


Book Description

In this eloquent plea for compassion and respect for all species, journalist and gardener Nancy Lawson describes why and how to welcome wildlife to our backyards. Through engaging anecdotes and inspired advice, profiles of home gardeners throughout the country, and interviews with scientists and horticulturalists, Lawson applies the broader lessons of ecology to our own outdoor spaces. Detailed chapters address planting for wildlife by choosing native species; providing habitats that shelter baby animals, as well as birds, bees, and butterflies; creating safe zones in the garden; cohabiting with creatures often regarded as pests; letting nature be your garden designer; and encouraging natural processes and evolution in the garden. The Humane Gardener fills a unique niche in describing simple principles for both attracting wildlife and peacefully resolving conflicts with all the creatures that share our world.




Underbug


Book Description

The award-winning journalist Lisa Margonelli, national bestselling author of Oil on the Brain: Petroleum’s Long, Strange Trip to Your Tank, investigates the environmental and economic impact termites inflict on human societies in this fascinating examination of one of nature’s most misunderstood insects. Are we more like termites than we ever imagined? In Underbug, the award-winning journalist Lisa Margonelli introduces us to the enigmatic creatures that collectively outweigh human beings ten to one and consume $40 billion worth of valuable stuff annually—and yet, in Margonelli’s telling, seem weirdly familiar. Over the course of a decade-long obsession with the little bugs, Margonelli pokes around termite mounds and high-tech research facilities, closely watching biologists, roboticists, and geneticists. Her globe-trotting journey veers into uncharted territory, from evolutionary theory to Edwardian science literature to the military industrial complex. What begins as a natural history of the termite becomes a personal exploration of the unnatural future we’re building, with darker observations on power, technology, historical trauma, and the limits of human cognition. Whether in Namibia or Cambridge, Arizona or Australia, Margonelli turns up astounding facts and raises provocative questions. Is a termite an individual or a unit of a superorganism? Can we harness the termite’s properties to change the world? If we build termite-like swarming robots, will they inevitably destroy us? Is it possible to think without having a mind? Underbug burrows into these questions and many others—unearthing disquieting answers about the world’s most underrated insect and what it means to be human.
