Synopsis When the World Runs Dry by : Nancy F. Castaldo

What would you do if you turned on the faucet one day and nothing happened? What if you learned the water in your home was harmful to drink? Water is essential for life on this planet, but not every community has the safe, clean water it needs. In When the World Runs Dry, award-winning science writer Nancy Castaldo takes readers from Flint, Michigan, and Newark, New Jersey, to Iran and Cape Town, South Africa, to explore the various ways in which water around the world is in danger, why we must act now, and why you’re never too young to make a difference. Topics include: Lead and water infrastructure problems, pollution, fracking contamination, harmful algal blooms, water supply issues, rising sea levels, and potential solutions.

Synopsis Spinning Flight by : Ralph D. Lorenz

More frisbees are sold each year than baseballs, basketballs and footballs combined. Yet these familiar flying objects have subtle and clever aerodynamic and gyrodynamic properties which are only recently being documented by wind tunnel and other studies. In common with other rotating bodies discussed in this readily accessible book, they are typically not treated in textbooks of aeronautics and the literature is scattered in a variety of places. This book develops the theme of disc-wings and spinning aerospace vehicles in parallel. Since many of the examples are recreational, anyone who enjoys these activities will likely find it profitable and enjoyable. In addition to spinning objects of various shapes, several exotic manned aircraft with disc planforms have been proposed and a prototypes built – these include a Nazi ‘secret weapon’ and the De Havilland Avrocar, also discussed in the book. Boomerangs represent another category of spinning aerodynamic body whose behavior can only be understood by coupling aerodynamics with gyrodynamics. The narrative, supported by equations and graphs, explains how the shape and throw of a boomerang relates to its trajectory. The natural world presents still other examples, namely the samaras or ‘seed-wings’ of many tree species, which autorotate during their descent, like a helicopter whose engine has failed. The flight performance of these spinning wings directly affects the dispersal and thus the evolutionary competitiveness of the trees concerned. Samara-type configurations are also considered for instrumentation and other payload dispersal applications. In short, the book discusses a range of familiar, connected, but largely undeveloped, topics in an accessible, but complete, manner. From the reviews of the first edition: "In his fascinating book Spinning Flight, Ralph Lorenz provides a rich feast of ... examples of spinning bodies ... . The book is well organized ... . The discussion in the book ... should be accessible to readers with some elementary understanding of aerodynamic principles. For the expert, the book is full of open problems ... . Its scope is extensive ... . In this respect, there may be something for everyone within its attractively designed cover ... ." (H. K. Moffatt, Nature, Vol. 444, December, 2006) "If you liked physics at school, then this book is for you. It concerns itself with flying objects that spin through the air, and even tells you how to impress your friends with the biomechanics of Frisbees. ... there is plenty of information at all levels, and the book has a wealth of detail that only an aerospace engineer like Lorenz could have come up with." (Len Fisher, BBC Focus, February, 2007)

Synopsis Orca Rescue! by : Donna Sandstrom

A captivating first-person story of a real-life orca rescue! When a young orca was spotted alone in Puget Sound, no one knew where she’d come from, but they knew it was dangerous for her to be left there alone. Scientists and researchers from two countries had to work together to determine where the orca came from, and then to decide how to save her. The riveting story is told by Donna Sandstrom, a citizen volunteer with the rescue effort. From identifying the orca as a missing calf named Springer, to transporting her to the north end of Vancouver Island, where she was reunited with her family, this book gives readers behind-the-scenes details on the only successful orca rescue and reunion ever! Kids will be thrilled to be part of the mission, when a little lost orca is brought home!
