Book Description
This book explains the nature of sound both as a physical phenomenon and as a sensation, how it travels through air and water, and how the hearing system evolved to convert these vibrations into sensations. Drawing on physics, biology, neuroscience, philosophy, literature, history, anecdote, and personal experience, "Now Hear This" is a wide-ranging exploration of the nature of sound and hearing that opens up a fascinating world of sounds from the mundane to the unusual and seeks above all to persuade the reader of the wisdom of John Cage’s advice that “Wherever we are what we hear is mostly noise. When we ignore it, it disturbs us. When we listen to it, we find it fascinating.”

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.

Book Description
Georges Perec, novelist, filmmaker and essayist, was one of the most inventive and original writers of the twentieth century. A fascinating aspect of his work is its intrinsically geographical nature. With major projects on space and place, Perec’s writing speaks to a variety of geographical, urban and architectural concerns, both in a substantive way, including a focus on cities, streets, homes and apartments, and in a methodological way, experimenting with methods of urban exploration and observation, classification, enumeration and taxonomy. Georges Perec’s Geographies is the first book to offer a rounded picture of Perec’s geographical interests. Divided into two parts, Part I, Perec’s Geographies, explores the geographies within Perec’s work in film, literature and radio, from descriptions of streets to the spaces of his texts, while Part II, Perecquian Geographies, explores geographies in a range of material and metaphorical forms, including photographic essays, soundscapes, theatre, dance and writing, created by those directly inspired by Perec. Georges Perec’s Geographies extends the body of Perec criticism beyond Literary and French Studies to disciplines including Geography, Urban Studies, Planning and Architecture to offer a complete and systematic examination of Georges Perec’s geographies. The diversity of readings and approaches will be of interest not only to Perec readers and fans but to students and researchers across these subjects.

Book Description
Humans have changed the Earth so profoundly that we’ve ushered in the first new geologic period since the ice ages. So, what are we going to do about it? Ever since Nobel Prize–winning atmospheric chemist Paul Crutzen coined the term "Anthropocene" to describe our current era—one in which human impact on the environment has pushed Earth into an entirely new geological epoch—arguments for and against the new designation have been raging. Finally, an official working group of scientists was created to determine once and for all whether we humans have tossed one too many plastic bottles out the car window and wrought a change so profound as to be on par with the end of the last ice age. In summer 2016, the answer came back: Yes. In Making the Most of the Anthropocene, scientist Mark Denny tackles this hard truth head-on and considers burning questions: How did we reach our present technological and ecological state? How are we going to cope with our uncertain future? Will we come out of this, or are we doomed as a species? Is there anything we can do about what happens next? This book • explains what the Anthropocene is and why it is important • offers suggestions for minimizing harm instead of fretting about an impending environmental apocalypse • combines easy-to-grasp scientific, technological, economic, and anthropological analyses In Making the Most of the Anthopocene, there are no equations, no graphs, and no impenetrable jargon. Instead, you'll find a fascinating cast of characters, including journalists from outer space, peppered moths, and unjustly maligned Polynesians. In his bright, lively voice, Denny envisions a future that balances reaction and reason, one in which humanity emerges bloody but unbowed—and in which those of us who are prepared can make the most of the Anthropocene.

Book Description
In Long Hops, physicist Mark Denny explains, in a clear, conversational style, the science of bird migration—from the intricacies of bird aeronautics to the newly unraveled mysteries of their magnetic compasses. While providing wherever possible examples of indigenous Hawaiian species, the book surveys the migration phenomenon as a whole, showing that birds are breathtaking works of engineering with spectacular capabilities for long-distance flights. Each year thousands of these hardy migrants fly 2,500 miles nonstop from Alaska to Hawai‘i. How do they endure such marathon journeys, and how on earth do they know which direction to travel over featureless ocean? In fact, many migratory journeys, in all parts of the world and performed by birds as small as warblers and as large as swans, cover much longer distances. After answering the “who, why, where, when” questions, Denny focuses on the questions of how: how researchers study bird migration; how they gather data from old-fashioned bird banding, high-tech satellite tracking, and other techniques; and—above all—how the birds do it. Throughout the book, concepts such as the physics of bird flight and the role of physical geography on navigation are explained in a relatively math-free way. Denny also examines past adaptations migrating birds have made to changing environments and the challenges they face in the future, as the world beneath them faces rapid climate change exacerbated by human activity.
