William began to explore science books in his village library, looking for a solution. There, he came up with the idea that would change his family's life forever: he could build a windmill. Made out of scrap metal and old bicycle parts, William's windmill brought electricity to his home and helped his family pump the water they needed to farm the land. Retold for a younger audience, this exciting memoir shows how, even in a desperate situation, one boy's brilliant idea can light up the world. Complete with photographs, illustrations, and an epilogue that will bring readers up to date on William's story, this is the perfect edition to read and share with the whole family.

    We can't see air moving, though we can watch it push clouds across the sky, or shake the leaves of a tree. We call moving air the wind. In this enlarged edition, find out about the wind - what causes it, how it can be used to help us, and how it affects the weather.

    Aspirin, the world's most widely used drug, is based on compounds originally extracted from the bark of a willow tree, and more than a quarter of medicines found on pharmacy shelves contain plant compounds. Now Western medicine, faced with health crises such as AIDS, Alzheimer's disease, and cancer, has begun to look to the healing plants used by indigenous peoples to develop powerful new medicines. Nowhere is the search more promising than in the Amazon, the world's largest tropical forest, home to a quarter of all botanical species on this planet—as well as hundreds of Indian tribes whose medicinal plants have never been studied by Western scientists. In Tales of a Shaman's Apprentice, ethnobotanist Mark J. Plotkin recounts his travels and studies with some of the most powerful Amazonian shamans, who taught him the plant lore their tribes have spent thousands of years gleaning from the rain forest.For more than a decade, Dr. Plotkin has raced against time to harvest and record new plants before the rain forests' fragile ecosystems succumb to overdevelopment—and before the Indians abandon their own culture and learning for the seductive appeal of Western material culture. Tales of a Shaman's Apprentice relates nine of the author's quests, taking the reader along on a wild odyssey as he participates in healing rituals; discovers the secret of curare, the lethal arrow poison that kills in minutes; tries the hallucinogenic snuff epena that enables the Indians to speak with their spirit world; and earns the respect and fellowship of the mysterious shamans as he proves that he shares both their endurance and their reverence for the rain forest. Mark Plotkin combines the Darwinian spirit of the great writer-explorers of the nineteenth century—curious, discursive, and rigorously scientific—with a very modern concern for the erosion of our environment and the vanishing culture of native peoples.

    In 1707, young Sarah Noble and her father traveled through the wilderness to build a new home for their family. “Keep up your courage, Sarah Noble,” her mother had said, but Sarah found that it was not always easy to feel brave inside. The dark woods were full of animals and Indians, too, and Sarah was only eight! The true story of Sarah’s journey is inspiring. And as she cares for her father and befriends her Indian neighbors, she learns that to be afraid and to be brave is the greatest courage of all. The New York Times Book Review described this book as one “to be long remembered for its beautifully written simplicity and dignity.”

    Beginning with the above questions, she began informally researching every affliction that she encountered in humans to learn whether it happened with animals, too. And usually, it did: dinosaurs suffered from brain cancer, koalas can catch chlamydia, reindeer seek narcotic escape in hallucinogenic mushrooms, stallions self-mutilate, and gorillas experience clinical depression. Natterson-Horowitz and science writer Kathryn Bowers have dubbed this pan-species approach to medicine zoobiquity. Here, they present a revelatory understanding of what animals can teach us about the human body and mind, exploring how animal and human commonality can be used to diagnose, treat, and heal patients of all species.

    Like Jared Diamond's Guns, Germs and Steel, Mapping Human History is a groundbreaking synthesis of science and history. Drawing on a wide range of sources, including the latest genetic research, linguistic evidence, and archaeological findings, Olson reveals the surprising unity among modern humans and "demonstrates just how naive some of our ideas about our human ancestry have been" (Discover).Olson offers a genealogy of all humanity, explaining, for instance, why everyone can claim Julius Caesar and Confucius as forebears. Olson also provides startling new perspectives on the invention of agriculture, the peopling of the Americas, the origins of language, the history of the Jews, and more.
