Argues that the tradition of critical theory has had significant problems dealing with the concept of nature and that their solutions require taking seriously the idea of nature as socially constructed.

The classic textbook on comparative biomechanics-revised and expandedWhy do you switch from walking to running at a specific speed? Why do tall trees rarely blow over in high winds? And why does a spore ejected into air at seventy miles per hour travel only a fraction of an inch? Comparative Biomechanics is the first and only textbook that takes a comprehensive look at the mechanical aspects of life-covering animals and plants, structure and movement, and solids and fluids. An ideal entry point into the ways living creatures interact with their immediate physical world, this revised and updated edition examines how the forms and activities of animals and plants reflect the materials available to nature, considers rules for fluid flow and structural design, and explores how organisms contend with environmental forces.Drawing on physics and mechanical engineering, Steven Vogel looks at how animals swim and fly, modes of terrestrial locomotion, organism responses to winds and water currents, circulatory and suspension-feeding systems, and the relationship between size and mechanical design. He also investigates links between the properties of biological materials-such as spider silk, jellyfish jelly, and muscle-and their structural and functional roles. Early chapters and appendices introduce relevant physical variables for quantification, and problem sets are provided at the end of each chapter. Comparative Biomechanics is useful for physical scientists and engineers seeking a guide to state-of-the-art biomechanics. For a wider audience, the textbook establishes the basic biological context for applied areas-including ergonomics, orthopedics, mechanical prosthetics, kinesiology, sports medicine, and biomimetics-and provides materials for exhibit designers at science museums.Problem sets at the ends of chaptersAppendices cover basic background informationUpdated and expanded documentation and materialsRevised figures and textIncreased coverage of friction, viscoelastic materials, surface tension, diverse modes of locomotion, and biomimetics

Describes how living things bump up against non-biological reality. Asking us wonder about the design of plants and animals around us, this book includes examples from every major group of animals and plants, with illustrative problems, and with suggestions of experiments that need only common household materials.

A provocative argument that environmental thinking would be better off if it dropped the concept of "nature" altogether and spoke instead of the built environment.

Glimpses of Creatures in Their Physical Worlds offers an eye-opening look into how the characteristics of the physical world drive the designs of animals and plants. These characteristics impose limits but also create remarkable and subtle opportunities for the functional biology of organisms. In particular, Steven Vogel examines the size and scale, and trade-offs among different physical processes. He pays attention to how the forms and activities of animals and plants reflect the materials available to nature, and he explores the unique constraints and possibilities provided by fluid flow, structural design, and environmental forces. 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.

Addresses biologists and general readers interested in biological fluid mechanics. This title discusses the relationship between fluid flow and biological design and includes sections on jet propulsion, biological pumps, swimming, blood flow, and surface waves, and on acceleration reaction and Murray's law.
