Witness to Disaster: Tsunamis (Witness to Disaster)
by Judy FradinIt’s another beautiful day of your paradise vacation in South Asia. You look out onto a calm sea on this day after Christmas, already looking forward to ringing in 2005. But why is the ocean receding so far from shore? Are those fish flapping around in the sand? Something is not right. Your island getaway is about to be devastated with the 80-foot-plus waves of one of the worst tsunamis in history. The 2004 Asian Tsunami was the result of the second largest earthquake ever recorded. Lasting over eight minutes, it was also the longest on record. The quake measured 9.0 on the Richter scale, large enough to vibrate the entire planet, violent enough to move an ocean. Through eyewitness accounts and dramatic photography, the first chapter of Tsunamis puts you in the terrifying path of the wave that washed ashore in many countries. The tsunami wiped out whole communities and claimed an estimated 230,000 lives. Tsunamis explores the science, history, and personal experience of tsunamis and shows kids what scientists are doing to develop early warning systems so we can survive such disasters in the future.

Witness Tree: Seasons of Change with a Century-Old Oak
by Lynda V. MapesAn intimate look at one majestic hundred-year-old oak tree through four seasons--and the reality of global climate change it reveals. In the life of this one grand oak, we can see for ourselves the results of one hundred years of rapid environmental change. It's leafing out earlier, and dropping its leaves later as the climate warms. Even the inner workings of individual leaves have changed to accommodate more CO2 in our atmosphere. Climate science can seem dense, remote, and abstract. But through the lens of this one tree, it becomes immediate and intimate. In Witness Tree, environmental reporter Lynda V. Mapes takes us through her year living with one red oak at the Harvard Forest. We learn about carbon cycles and leaf physiology, but also experience the seasons as people have for centuries, watching for each new bud, and listening for each new bird and frog call in spring. We savor the cadence of falling autumn leaves, and glory of snow and starry winter nights. Lynda takes us along as she climbs high into the oak's swaying boughs, and scientists core deep into the oak's heartwood, dig into its roots and probe the teeming life of the soil. She brings us eye-level with garter snakes and newts, and alongside the squirrels and jays devouring the oak's acorns. Season by season she reveals the secrets of trees, how they work, and sustain a vast community of lives, including our own. The oak is a living timeline and witness to climate change. While stark in its implications, Witness Tree is a beautiful and lyrical read, rich in detail, sweeps of weather, history, people, and animals. It is a story rooted in hope, beauty, wonder, and the possibility of renewal in people's connection to nature.

The Wizard and the Prophet: Science and the Future of Our Planet
by Charles C. MannTwo Groundbreaking Scientists and Their Conflicting Visions of the Future of Our Planet'Does the earth’s finite carrying capacity mean economic growth has to stop? That momentous question is the subject of Charles Mann’s brilliant book.' Wall Street JournalIn forty years, the population of the Earth will reach ten billion. Can our world support so many people? What kind of world will it be? In this unique, original and important book, Charles C. Mann illuminates the four great challenges we face – food, water, energy, climate change – through an exploration of the crucial work and wide-ranging influence of two little-known twentieth-century scientists, Norman Borlaug and William Vogt.Vogt (the Prophet) was the intellectual forefather of the environmental movement, and believed that in our using more than the planet has to give, our prosperity will bring us to ruin. Borlaug’s research in the 1950s led to the development of modern high-yield crops that have saved millions from starvation. The Wizard of Mann’s title, he believed that science will continue to rise to the challenges we face.Mann tells the stories of these scientists and their crucial influence on today’s debates as his story ranges from Mexico to India, across continents and oceans and from the past and the present to the future. Brilliantly original in concept, wryly observant and deeply researched, The Wizard and the Prophet is essential reading for readers of Yuval Noah Harari’s Sapiens or Jared Diamond’s Guns, Germs and Steel, for anyone interested in how we got here and in the future of our species.

WKB Approximation in Atomic Physics
by Boris Mikhailovich Karnakov Vladimir Pavlovich KrainovThis book has evolved from lectures devoted to applications of the Wentzel - Kramers – Brillouin- (WKB or quasi-classical) approximation and of the method of 1/N −expansion for solving various problems in atomic and nuclear physics. The intent of this book is to help students and investigators in this field to extend their knowledge of these important calculation methods in quantum mechanics. Much material is contained herein that is not to be found elsewhere. WKB approximation, while constituting a fundamental area in atomic physics, has not been the focus of many books. A novel method has been adopted for the presentation of the subject matter, the material is presented as a succession of problems, followed by a detailed way of solving them. The methods introduced are then used to calculate Rydberg states in atomic systems and to evaluate potential barriers and quasistationary states. Finally, adiabatic transition and ionization of quantum systems are covered.
Wo sind sie alle?: Fünfzig Lösungen für das Fermi-Paradoxon
by Stephen WebbAllein in unserer Galaxie gibt es etwa eine Milliarde erdähnlicher Planeten. Im sichtbaren Universum finden sich etwa 200 Milliarden Galaxien. Liegt es daher nicht nahe, dass sich irgendwo da draußen eine Zivilisation entwickelt hat, die mindestens genauso fortgeschritten ist wie unsere eigene? Die schieren Zahlen verlangen fast danach. Aber: Wieso sind wir dann noch nicht auf Botschaften, Artefakte oder sonstige Hinweise auch nur einer einzigen außerirdischen Zivilisation gestoßen?In diesem Buch führt Stephen Webb durch fünfzig überzeugende und faszinierende Lösungen des berühmten Fermi-Paradoxons, die kurzweilig präsentiert zum Nachdenken und auch Schmunzeln anregen.
Wolf Nation: The Life, Death, and Return of Wild American Wolves (A Merloyd Lawrence Book)
by Brenda PetersonIn the tradition of Peter Matthiessen's Wildlife in America or Aldo Leopold, Brenda Peterson tells the 300-year history of wild wolves in America. It is also our own history, seen through our relationship with wolves. The earliest Americans revered them. Settlers zealously exterminated them. Now, scientists, writers, and ordinary citizens are fighting to bring them back to the wild. Peterson, an eloquent voice in the battle for twenty years, makes the powerful case that without wolves, not only will our whole ecology unravel, but we'll lose much of our national soul.
