Usually I decide to save the money so I do not have to earn more. En extremis, I repeat the old Yankee marching chant like a mantra: Make do! Wear it out! When it is gone, do without! Bum, Bum! Bum bi Dum! Bum bi di Dum, Bum bi Dum!

    The lens he invented was a brilliant feat of engineering that made lighthouses blaze many times brighter, farther, and more efficiently. Battling the establishment, his own poor health, and the limited technology of the time, Fresnel was able to achieve his goal of illuminating the entire French coast. At first, the British sought to outdo the new Fresnel-equipped lighthouses as a matter of national pride. Americans, too, resisted abandoning their primitive lamps, but the superiority of the Fresnel lens could not be denied for long. Soon, from Dunkirk to Saigon, shores were brightened with it.  The Fresnel legacy played an important role in geopolitical events, including the American Civil War. No sooner were Fresnel lenses finally installed along U.S. shores than they were drafted: the Union blockaded the Confederate coast; the Confederacy set about thwarting it by dismantling and hiding or destroying the powerful new lights.Levitt’s scientific and historical account, rich in anecdote and personality, brings to life the fascinating untold story of Augustin Fresnel and his powerful invention.

    In this travel narrative, she tells the story of her on-the-ground discovery of the relics and memories a few thousand mountain residents left behind when the government used eminent domain to kick the people off their land to create the park.With historic maps and notes from hikers who explored before her, Eisenfeld and her husband hike, backpack, and bushwhack the hills and the hollows of this beloved but misbegotten place, searching for stories. Descendants recount memories of their ancestors “grieving themselves to death,” and they continue to speak of their people’s displacement from the land as an untold national tragedy.Shenandoah: A Story of Conservation and Betrayal is Eisenfeld’s personal journey into the park’s hidden past based on her off-trail explorations. She describes the turmoil of residents’ removal as well as the human face of the government officials behind the formation of the park. In this conflict between conservation for the benefit of a nation and private land ownership, she explores her own complicated personal relationship with the park—a relationship she would not have without the heartbreak of the thousands of people removed from their homes.Purchase the audio edition.

    In fact, a plethora of parasites affect our behavior in ways we have barely begun to understand.  In this mind-bending book, McAuliffe reveals the eons-old war between parasites and other creatures that is playing out in our very own bodies. And more surprising still, she uncovers the decisive role that parasites may have played in the rise and demise of entire civilizations. Our obsession with cleanliness and our experience of disgust are both evolutionary tools for avoiding infection, but they evolved differently for different populations. Political, social, and religious differences among societies may be caused, in part, by the different parasites that prey on us. In the tradition of Jared Diamond’s Guns, Germs, and Steel and Neil Shubin’s Your Inner Fish, This Is Your Brain on Parasites is both a journey into cutting-edge science and a revelatory examination of what it means to be human.

    As she grows into adulthood, only a few of her eggs mature, are released into the oviduct, and are fertilized by sperm stored from copulation that took place days or weeks earlier. Within a matter of hours, the fragile yolk is surrounded by albumen and the whole is gradually encased within a turquoise jewel of a shell. Soon afterward the fully formed egg is expelled onto a bare rocky ledge, where it will be incubated for four weeks before another chick emerges and the life cycle begins again. The Most Perfect Thing is about how eggs in general are made, fertilized, developed, and hatched. The eggs of most birds spend just 24 hours in the oviduct; however, that journey takes 48 hours in cuckoos, which surreptitiously lay their eggs in the nests of other birds. From the earliest times, the study of birds' ovaries and ova (eggs) played a vital role in the quest to unravel the mysteries of fertilization and embryo development in humans. Birkhead uses birds' eggs as wondrous portals into natural history, enlivened by the stories of naturalists and scientists, including Birkhead and his students, whose discoveries have advanced current scientific knowledge of reproduction.

    In this revised edition, Merlin D. Tuttle, founder and science director of Bat Conservation International in Austin, Texas, offers bat aficionados the most up-to-date bat facts, including a wealth of new information on attracting bats and building bat houses and a totally revamped key to the identification of common North American species.

    Their mission? Tracking down the elusive Tasmanian tiger. Tragically, this mysterious, striped predator was hunted into extinction in the early part of the twentieth century. Or was it? Journeying first to the Australian mainland and then south to the wild island of Tasmania, these young naturalists brave a series of bizarre misadventures and uproarious wildlife encounters in their obsessive search for the long-lost beast. Filled with Rockman’s stunning drawings of flora and fauna originally crafted from river mud, wombat scat, and even the artist’s own blood, Carnivorous Nights is a hip and hilarious account of an unhinged safari, as well as a fascinating portrayal of a wildly unique part of the world.Carniverous Nights is:One of the New York Public Library's "25 Books to Remember from 2005"A New York Public Library Books for the Teen Age, 2006 selection

    The book uses the theme of evolution to develop a broad-scale view of animal diversity--students focus not only the organisms themselves, but also the processes that produce evolutionary diversity. The book is unique in its comprehensive survey of zoological diversity and its emphasis on evolutionary, systematic and ecological principles, all in one package.

    lifelike detail... this easily readable book should appeal to dinosaur enthusiasts of all ages." -Science NewsThe Complete Guide to Prehistoric Life. The book's concise, jargon-free text and full color illustrations bring the primordial world to vivid photo-realistic life. In-depth profiles of 112 kinds of beasts cover physical characteristics, lifestyle, habitat and behavior. Throughout, "fascinating fact" sidebars offer additional bits of "dinotrivia." But there is more than dinosaurs here. Readers will find creatures from triobites to early human beings. At the heart of the book are 350 richly detailed and lifelike color illustrations -- accompanied by comprehensive text -- which are the result of pioneering work by the Emmy award-winning creative team at Framestore CFC. Using animation, graphic effects and filmmaking, they recreated awe-inspiring prehistoric creatures and the world they lived in. These images are now reproduced to thrill readers.The Complete Guide to Prehistoric Life was published to accompany two BBC TV prime-time programs, Life Before Dinosaurs and Walking with Life, both part of the Discovery Channel's award-winning Walking with Dinosaurs series.

    Often black and white or tinted sepia, these remarkable images have been taken mainly in zoos or wildlife parks, and in some cases depict the last known individual of the species. Lost Animals is a unique photographic record of extinction, presented by a world authority on vanished animals. Richly illustrated throughout, this handsome book features photographs dating from around 1870 to as recently as 2004, the year that witnessed the demise of the Hawaiian Po'ouli. From a mother Thylacine and her pups to birds such as the Heath Hen and the Carolina Parakeet, Errol Fuller tells the story of each animal, explains why it became extinct, and discusses the circumstances surrounding the photography.Covering 28 extinct species, Lost Animals includes familiar examples like the last Passenger Pigeon, Martha, and one of the last Ivory-billed Woodpeckers, photographed as it peers quizzically at the hat of one of the biologists who has just ringed it. But the book includes rare images as well, many never before published. Collected together here for the first time, these photographs provide a tangible link to animals that have now vanished forever, in a book that brings the past to life while delivering a warning for the future.Poignant and compelling, Lost Animals also includes a concise introduction that looks at the earliest days of animal photography, and an appendix of drawings and paintings of the species covered.

    The prairies are the heartland of the continent, a vast, windswept plain that flows from Alberta south to Texas and from the Rockies east to the Mississippi River. This is big sky country, and until recently, one of the richest and most magnificent natural grasslands in the world. Today, however, the North American prairies are among the most altered environments on Earth. Thorough, detailed, and scientifically up-to-date, Prairie: A Natural History provides a comprehensive, nontechnical guide to the biology and ecology of this fabled environment, offering a view of the past, a vision for the future, and a clear focus on the present. Sidebars throughout highlight various grasslands species, tell fascinating natural history and conservation stories, and present the traditional Native American view of the prairie and its inhabitants.

    Gee’s grand tour enthusiastically details the narrative underlying life’s erratic and often whimsical exploration of biological form and function.” —Adrian Woolfson, The Washington PostIn the tradition of Richard Dawkins, Bill Bryson, and Simon Winchester—An entertaining and uniquely informed narration of Life's life story.In the beginning, Earth was an inhospitably alien place—in constant chemical flux, covered with churning seas, crafting its landscape through incessant volcanic eruptions. Amid all this tumult and disaster, life began. The earliest living things were no more than membranes stretched across microscopic gaps in rocks, where boiling hot jets of mineral-rich water gushed out from cracks in the ocean floor.Although these membranes were leaky, the environment within them became different from the raging maelstrom beyond. These havens of order slowly refined the generation of energy, using it to form membrane-bound bubbles that were mostly-faithful copies of their parents—a foamy lather of soap-bubble cells standing as tiny clenched fists, defiant against the lifeless world. Life on this planet has continued in much the same way for millennia, adapting to literally every conceivable setback that living organisms could encounter and thriving, from these humblest beginnings to the thrilling and unlikely story of ourselves.In A (Very) Short History of Life on Earth, Henry Gee zips through the last 4.6 billion years with infectious enthusiasm and intellectual rigor. Drawing on the very latest scientific understanding and writing in a clear, accessible style, he tells an enlightening tale of survival and persistence that illuminates the delicate balance within which life has always existed.

    From menacing moonshiners and armed bandits to charging elephants and man-eating tigers, Merlin Tuttle has stopped at nothing to find and protect bats on every continent they inhabit. Enamored of bats ever since discovering a colony in a cave as a boy, Tuttle saw how effective photography could be in persuading people not to fear bats, and he has spent his career traveling the world to document them.Few people realize how sophisticated and intelligent bats are. Tuttle shares research showing that frog-eating bats can identify frogs by their calls, that vampire bats have a social order similar to that of primates, and that bats have remarkable memories. Bats also provide enormous benefits by eating crop pests, pollinating plants, and carrying seeds needed for reforestation. They save farmers billions of dollars annually and are essential to a healthy planet.Sharing highlights from a lifetime of adventure and discovery, Tuttle takes us to the frontiers of bat research and conservation and forever changes the way we see these poorly understood yet fascinating creatures.
