From an award-winning teacher, “a delightful and instructive accessory to an introductory physics course” (Physics World). Physicists use “back-of-the-envelope” estimates to check whether or not an idea could possibly be right. In many cases, the approximate solution is all that is needed. This compilation of 101 examples of back-of-the-envelope calculations celebrates a quantitative approach to solving physics problems. Drawing on a lifetime of physics research and nearly three decades as the editor of The Physics Teacher, Clifford Swartz—a winner of two awards from the American Association of Physics Teachers—provides simple, approximate solutions to physics problems that span a broad range of topics. What note do you get when you blow across the top of a Coke bottle? Could you lose weight on a diet of ice cubes? How can a fakir lie on a bed of nails without getting hurt? Does draining water in the northern hemisphere really swirl in a different direction than its counterpart below the equator? In each case, only a few lines of arithmetic and a few natural constants solve a problem to within a few percent. Covering such subjects as astronomy, magnetism, optics, sound, heat, mechanics, waves, and electricity, this book provides a rich source of material for teachers and anyone interested in the physics of everyday life. “This is a book that will help make the study of physics fun and relevant.” —Mark P. Silverman, author of Waves and Grains: Reflections on Light and LearningVer libro
An inspirational story of one man’s quest to save sun bears from extinction. In Asia, adult sun bears are poached for body parts which are thought to have medicinal properties. Orphaned cubs are kept illegally as pets. Natural habitat is disappearing fast. Malaysian ecologist Dr Wong Siew Te, or ‘papa bear’, is trying to save sun bears from extinction. His quest takes him from Malaysia to Taiwan, where he studies animal husbandry; to Montana, where he learns to trap grizzly bears; and on to Borneo to research bears in the dense rainforest. Wong struggles to raise funds to create a unique rescue centre for sun bears, and in 2017 he is acknowledged as a CNN Hero—proving one person can make a difference. Australian author Dr Sarah Pye takes readers on a journey of discovery, introducing individual sun bears she has come to know: Natalie, who learns to survive without her mother; Bongkud, who is struck by lightning; Gutuk, who is too scared to go outside; and Debbie, who grabs her chance at freedom. Saving Sun Bears is Wong’s story—and theirs.Ver libro
★★★ Gone in an instant ★★★ Pompeii was one of the most advanced cities of its time; it had a complex water system, gymnasium, and amphitheater. Despite its advancements, there was one thing it wasn't ready for: Mount Vesuvius--the volcano that led to its ultimate doom. The 79 AD eruption of Mount Vesuvius was one of the worst disasters in all of European history. In a near instant, over 15,000 people were dead and a city was completely destroyed. This book looks at the rise, fall, and rediscovery of the great city of Pompeii.Ver libro
How did a deadly genetic disease help our ancestors survive the bubonic plagues of Europe? Was diabetes evolution's response to the last Ice Age? Will a visit to the tanning salon help bring down your cholesterol? Why do we age? Why are some people immune to HIV? Can your genes be turned on—or off? Survival of the Sickest reveals the answers to these and many other questions as it unravels the amazing connections between evolution, disease, and human health today. Joining the ranks of modern myth busters, Dr. Sharon Moalem turns our current understanding of illness on its head and challenges us to fundamentally change the way we think about our bodies, our health, and our relationship to just about every other living thing on earth, from plants and animals to insects and bacteria. Survival of the Sickest is filled with fascinating insights and cutting-edge research, presented in a way that is both accessible and utterly absorbing. This is a book about the interconnectedness of all life on earth—and, especially, what that means for us. Read it. You're already living it. Read by Eric CongerVer libro
The news about wildlife is dire—more than 900 species have been wiped off the planet since industrialization. Against this bleak backdrop, however, there are also glimmers of hope and crucial lessons to be learned from animals that have defied global trends toward extinction: bears in Italy, bison in North America, whales in the Atlantic. These populations are back from the brink, some of them in numbers unimaginable in a century. How has this happened? What shifts in thinking did it demand? In crisp, transporting prose, Christopher Preston reveals the mysteries and challenges at the heart of these resurgences.Drawing on compelling personal stories from the researchers, Indigenous people, and activists who know the creatures best, Preston weaves together a gripping narrative of how some species are taking back vital, ecological roles. Each section of the book offers a philosophical shift in how humans ought to think about animals, passionately advocating for the changes in attitude necessary for wildlife recovery.Tenacious Beasts is quintessential nature writing for the Anthropocene, touching on different facets of ecological restoration from Indigenous knowledge to rewilding practices. More important, perhaps, the book offers a road map—and a measure of hope—for a future in which humans and animals can once again coexist.Ver libro
