Book Description
Selected by Choice Magazine as an Outstanding Academic Title for 2003 David E. Alexander's fascination with the many animals and plants that have harnessed the air is evident in Nature's Flyers: Birds, Insects, and the Biomechanics of Flight, a detailed account of our current scientific understanding of the primary aspects of flight in nature. Instead of relying on elaborate mathematical equations, Alexander explains the physical basis of flight with sharp prose and clear diagrams. Drawing upon bats, birds, insects, pterosaurs, and even winged seeds, he details the basic operating principles of wings and then moves progressively through more complex modes of animal flight, including gliding, flapping, and maneuvering. In addition to summarizing the latest thinking about flight's energy costs, Alexander presents a holistic view of flight and its ramifications as he explores the ecology and evolution of flying animals, addressing behaviorally important topics such as migration and navigation. With somewhat surprising answers, the author then concludes his study by examining the extent to which natural flight has been inspiring or instructive for the architects of human flight—airplane designers and engineers.

Book Description
What do a bumble bee and a 747 jet have in common? It’s not a trick question. The fact is they have quite a lot in common. They both have wings. They both fly. And they’re both ideally suited to it. They just do it differently. Why Don’t Jumbo Jets Flap Their Wings? offers a fascinating explanation of how nature and human engineers each arrived at powered flight. What emerges is a highly readable account of two very different approaches to solving the same fundamental problems of moving through the air, including lift, thrust, turning, and landing. The book traces the slow and deliberate evolutionary process of animal flight—in birds, bats, and insects—over millions of years and compares it to the directed efforts of human beings to create the aircraft over the course of a single century. Among the many questions the book answers: Why are wings necessary for flight? How do different wings fly differently? When did flight evolve in animals? What vision, knowledge, and technology was needed before humans could learn to fly? Why are animals and aircrafts perfectly suited to the kind of flying they do? David E. Alexander first describes the basic properties of wings before launching into the diverse challenges of flight and the concepts of flight aerodynamics and control to present an integrated view that shows both why birds have historically had little influence on aeronautical engineering and exciting new areas of technology where engineers are successfully borrowing ideas from animals.

Book Description
Nature's Machines: An Introduction to Organismal Biomechanics presents the fundamental principles of biomechanics in a concise, accessible way while maintaining necessary rigor. It covers the central principles of whole-organism biomechanics as they apply across the animal and plant kingdoms, featuring brief, tightly-focused coverage that does for biologists what H. M. Frost's 1967 Introduction to Biomechanics did for physicians. Frequently encountered, basic concepts such as stress and strain, Young's modulus, force coefficients, viscosity, and Reynolds number are introduced in early chapters in a self-contained format, making them quickly available for learning and as a refresher. More sophisticated, integrative concepts such as viscoelasticity or properties of hydrostats are covered in the later chapters, where they draw on information from multiple earlier sections of the book. Animal and plant biomechanics is now a common research area widely acknowledged by organismal biologists to have broad relevance. Most of the day-to-day activities of an animal involve mechanical processes, and to the extent that organisms are shaped by adaptive evolution, many of those adaptations are constrained and channelized by mechanical properties. The similarity in body shape of a porpoise and a tuna is no coincidence. Many may feel that they have an intuitive understanding of many of the mechanical processes that affect animals and plants, but careful biomechanical analyses often yield counterintuitive results: soft, squishy kelp may be better at withstanding pounding waves during storms than hard-shelled mollusks; really small swimmers might benefit from being spherical rather than streamlined; our bones can operate without breaking for decades, whereas steel surgical implants exhibit fatigue failures in a few months if not fully supported by bone. - Offers organismal biologists and biologists in other areas a background in biomechanics to better understand the research literature and to explore the possibility of using biomechanics approaches in their own work - Provides an introductory presentation of the everyday mechanical challenges faced by animals and plants - Functions as recommended or required reading for advanced undergraduate biology majors taking courses in biomechanics, supplemental reading in a general organismal biology course, or background reading for a biomechanics seminar course

Book Description
A review of the current state of the art of biomimetics, this book documents key biological solutions that provide a model for innovations in engineering and science. Leading experts explore a wide range of topics, including artificial senses and organs; mimicry at the cell-materials interface; modeling of plant cell wall architecture; biomimetic composites; artificial muscles; biomimetic optics; and the mimicking of birds, insects, and marine biology. The book also discusses applications of biomimetics in manufacturing, products, medicine, and robotics; biologically inspired design as a tool for interdisciplinary education; and the biomimetic process in artistic creation.

Book Description
Design in engineering and science has often been inspired by nature. This has been more evident in recent years, after a period during which our civilization thought in terms of taming rather than working in harmony with nature. The consequences of that approach are still with us and have resulted in a world increasingly homogenized, lacking in biodiversity and with increased pollution. Mankind has been slow to learn and even slower to apply the lessons that nature offers, in spite of the urgency of our predicament. This book contains papers presented at the fourth International Conference on Comparing Design in Nature with Science and Engineering . The emphasis of this Volume is on engineering and architectural applications and on biomimetics, reflecting in some measure current interest in finding environmentally friendly solutions which also optimize the use of natural resources. The contributions have been arranged into the following topics: Biomimetics; Shape and Form in Engineering Nature; Nature and Architectural Design; Natural Materials and Surfaces; Complexity; and Education.

Book Description
Ask anybody what superpower they wished to possess and odds are the answer just might be "the ability to fly." What is it about soaring through the air held up by the power of one's own body that has captivated humans for so long? David Alexander examines the evolution of flight in the only four animals to have evolved this ability: insects, pterosaurs, birds, and bats. With an accessible writing style grounded in rigorous research, Alexander breaks new ground in a field that has previously been confined to specialists. While birds have received the majority of attention from flight researchers, Alexander pays equal attention to all four groups of flyers-something that no other book on the subject has done before now. In a streamlined and captivating way, David Alexander demonstrates the links between the tiny 2-mm thrip and the enormous albatross with the 12 feet wingspan used to cross oceans. The book delves into the fossil record of flyers enough to satisfy the budding paleontologist, while also pleasing ornithologists and entomologists alike with its treatment of animal behavior, flapping mechanisms, and wing-origin theory. Alexander uses relatable examples to draw in readers even without a natural interest in birds, bees, and bats. He takes something that is so off-limits and unfamiliar to humans-the act of flying-and puts it in the context of experiences that many readers can relate to. Alexander guides readers through the anomalies of the flying world: hovering hummingbirds, unexpected gliders (squirrels, for instance), and the flyers that went extinct (pterosaurs). Alexander also delves into wing-origin theory and explores whether birds entered the skies from the trees down (as gliders) or from the ground up (as runners) and uses the latest fossil evidence to present readers with an answer.
