Bats


Book Description

There are more than 1,300 species of bats—or almost a quarter of the world’s mammal species. But before you shrink in fear from these furry “creatures of the night,” consider the bat’s fundamental role in our ecosystem. A single brown bat can eat several thousand insects in a night. Bats also pollinate and disperse the seeds for many of the plants we love, from bananas to mangoes and figs. Bats: A World of Science and Mystery presents these fascinating nocturnal creatures in a new light. Lush, full-color photographs portray bats in flight, feeding, and mating in views that show them in exceptional detail. The photos also take the reader into the roosts of bats, from caves and mines to the tents some bats build out of leaves. A comprehensive guide to what scientists know about the world of bats, the book begins with a look at bats’ origins and evolution. The book goes on to address a host of questions related to flight, diet, habitat, reproduction, and social structure: Why do some bats live alone and others in large colonies? When do bats reproduce and care for their young? How has the ability to fly—unique among mammals—influenced bats’ mating behavior? A chapter on biosonar, or echolocation, takes readers through the system of high-pitched calls bats emit to navigate and catch prey. More than half of the world’s bat species are either in decline or already considered endangered, and the book concludes with suggestions for what we can do to protect these species for future generations to benefit from and enjoy. From the tiny “bumblebee bat”—the world’s smallest mammal—to the Giant Golden-Crowned Flying Fox, whose wingspan exceeds five feet, A Battery of Bats presents a panoramic view of one of the world’s most fascinating yet least-understood species.




Flow Sensing in Air and Water


Book Description

In this book, leading scientists in the fields of sensory biology, neuroscience, physics and engineering explore the basic operational principles and behavioral uses of flow sensing in animals and how they might be applied to engineering applications such as autonomous control of underwater or aerial vehicles. Although humans possess no flow-sensing abilities, countless aquatic (e.g. fish, cephalopods and seals), terrestrial (e.g. crickets and spiders) and aerial (e.g. bats) animals have flow sensing abilities that underlie remarkable behavioral feats. These include the ability to follow silent hydrodynamic trails long after the trailblazer has left the scene, to form hydrodynamic images of their environment in total darkness, and to swim or fly efficiently and effortlessly in the face of destabilizing currents and winds.

Hitting with Torque


Book Description

Paul Petricca draws on his experience as a coach, player, blogger, and student of baseball and softball to share what hes learned about hitting in this essential guide for players seeking dramatic results at the plate. The author presents easy to understand hitting mechanics highlighting how the engineering concept of torque can be applied to hitting and is often the difference between a weak groundball or a long home run. Topics covered include understanding where hitting power really comes from and the importance of increasing bat speed through the fundamentals of a repeatable and powerful rotational swing. Hitters of all ages who adopt his eight hitting keys will enjoy a dramatic increase in bat speed and power almost immediately. Hitting with Torque is more than a set of hitting mechanics---its a mindset. Readers will be challenged to look past the worn-out hitting theories and myths that have been holding back hitters from reaching their full potential. With an open mind and practice, all hitters can unlock the power and consistency that is Hitting with Torque.




Biosonar


Book Description

Two groups of animals, bats and odontocetes (toothed whales), have independently developed the ability to orient and detect prey by biosonar (echolocation). This active mechanism of orientation allows these animals to operate under low light conditions. Biosonar is a conceptual overview of what is known about biosonar in bats and odontocetes. Chapters are written by bat and odontocetes experts, resulting in collaborations that not only examine data on both animals, but also compare and contrast mechanisms. This book provides a unique insight that will help improve our understanding of biosonar in both animal groups.




Five Steps to an Efficient Swing


Book Description

The following information provided inside this manual is meant to provide baseball players a better understanding of what really happens during a good efficient baseball swing, as well as a mental approach to hitting. All information in this book is based upon personal playing experience at the high school and junior college level. Also including are helpful insights from current and former college and professional players that I have worked with over the years, hundreds of hours of research using video analysis, hundreds of hours of group and personal instruction umpiring and instructing experience.
