Summary : Are the United States and China on a collision course? In response to remarks made by Donald Trump’s secretary of state, China’s state-run newspaper Global Times asserted, "Unless Washington plans to wage a large-scale war in the South China Sea, any other approaches to prevent Chinese access to the [disputed] islands will be foolish." Some experts contend that conflict is inevitable when an established power does not make sufficient room for a rising power. In this timely new work, renowned professor of international relations Amitai Etzioni explains why this would be disastrous and points to the ways the two nations can avoid war. The United States is already preparing for a war with China, Etzioni reveals. However, major differences of opinion exist among experts on the extent of military commitment required, and no plan has been formally reviewed by either Congress or the White House, nor has any been subjected to a public debate. Etzioni seeks here to provide a context for this long overdue discussion and to explore the most urgent questions: How aggressive is China? How powerful is it? Does it seek merely regional influence, or regional dominance, or to replace the United States as the global superpower? The most effective means of avoiding war, several experts argue, requires integrating China into the prevailing rule-based, liberal, international order. Etzioni spells out how this might be achieved and considers what can be done to improve the odds such an integration will take place. Others call for containing or balancing China, and Etzioni examines the risk posed by our alliances with various countries in the region, particularly India and Pakistan. With insight and clarity Etzioni presents our best strategy to reduce tension between the two powers, mapping out how the United States can accommodate China’s regional rise without undermining its core interests, its allies, and the international order.

Summary : You too can follow in the steps of the great astronomers such as Hipparchus, Galileo, Kepler and Hubble, who all contributed so much to our modern understanding of the cosmos. This book gives the student or amateur astronomer the following tools to replicate some of these seminal observations from their own homes: With your own eyes: Use your own observations and measurements to discover and confirm the phenomena of the seasons, the analemma and the equation of time, the logic behind celestial coordinates, and even the precession of the equinoxes. With a consumer-grade digital camera: Record the changing brightness of an eclipsing binary star and show that a pulsating star changes color as it brightens and dims. Add an inexpensive diffraction grating to your camera and see the variety of spectral features in the stars, and demonstrate that the Sun’s spectrum is similar to one particular type of stellar spectrum. With a backyard telescope: Add a CCD imager and you can measure the scale of the Solar System and the distance to a nearby star. You could even measure the distance to another galaxy and observe the cosmological redshift of the expanding universe. Astronomical Discoveries You Can Make, Too! doesn’t just tell you about the development of astronomy; it shows you how to discover for yourself the essential features of the universe.

Summary : From the New York Times bestselling author of Rump, comes the true story behind another unlikely hero: a grumpy dwarf who gets tangled up in Snow White's feud with the wicked queen. Ever since he was a dwarfling, Borlen (nicknamed "Grump") has dreamed of visiting The Surface, so when opportunity knocks, he leaves his cavern home behind. At first, life aboveground is a dream come true. Queen Elfrieda Veronika Ingrid Lenore (E.V.I.L.) is the best friend Grump always wanted, feeding him all the rubies he can eat and allowing him to rule at her side in exchange for magic and information. But as time goes on, Grump starts to suspect that Queen E.V.I.L. may not be as nice as she seems. . . . When the queen commands him to carry out a horrible task against her stepdaughter Snow White, Grump is in over his head. He's bound by magic to help the queen, but also to protect Snow White. As if that wasn't stressful enough, the queen keeps bugging him for updates through her magic mirror! He'll have to dig deep to find a way out of this pickle, and that's enough to make any dwarf Grumpy indeed.
