Decipher


Book Description

Ancient monuments all over the world - from the Pyramids of Giza, to Mexico, to the ancient sites of China - are also awakening, reacting to a brewing crisis not of this earth, connecting to each other in some kind of ancient global network. A small group of scientists is assembled to attempt to unravel the mystery. What they discover will change the world. Imagine that 12,000 years ago it really did rain for 40 days and 40 nights. That storms reigned supreme. Imagine that survivors of human civilization really were forced to take to boats or hide out in caves on mountaintops. Then consider that these same myths from around the world predict this kind of devastation will occur time and again. What could cause such a catastrophe? What occurs in nature with such frightening and predictable regularity? A pulsar. But this is not just any pulsar - the ordinary type that pulses once a second, a minute, or even a week. This pulses once every 12,000 years and sends out a gravity wave of such ferocity it beggars belief. Not only that, it's closer than anybody has ever imagined. For it lives in our own backyard. It is the Sun.

Bloody Genius


Book Description

Virgil Flowers will have to watch his back--and his mouth--as he investigates a college culture war turned deadly in another one of Sandford's "madly entertaining Virgil Flowers mysteries" (New York Times Book Review). At the local state university, two feuding departments have faced off on the battleground of science and medicine. Each carries their views to extremes that may seem absurd, but highly educated people of sound mind and good intentions can reasonably disagree, right? Then a renowned and confrontational scholar winds up dead, and Virgil Flowers is brought in to investigate . . . and as he probes the recent ideological unrest, he soon comes to realize he's dealing with people who, on this one particular issue, are functionally crazy. Among this group of wildly impassioned, diametrically opposed zealots lurks a killer, and it will be up to Virgil to sort the murderer from the mere maniacs.

How Asia Works


Book Description

“A good read for anyone who wants to understand what actually determines whether a developing economy will succeed.” —Bill Gates, “Top 5 Books of the Year” An Economist Best Book of the Year from a reporter who has spent two decades in the region, and who the Financial Times said “should be named chief myth-buster for Asian business.” In How Asia Works, Joe Studwell distills his extensive research into the economies of nine countries—Japan, South Korea, Taiwan, Indonesia, Malaysia, Thailand, the Philippines, Vietnam, and China—into an accessible, readable narrative that debunks Western misconceptions, shows what really happened in Asia and why, and for once makes clear why some countries have boomed while others have languished. Studwell’s in-depth analysis focuses on three main areas: land policy, manufacturing, and finance. Land reform has been essential to the success of Asian economies, giving a kick-start to development by utilizing a large workforce and providing capital for growth. With manufacturing, industrial development alone is not sufficient, Studwell argues. Instead, countries need “export discipline,” a government that forces companies to compete on the global scale. And in finance, effective regulation is essential for fostering, and sustaining growth. To explore all of these subjects, Studwell journeys far and wide, drawing on fascinating examples from a Philippine sugar baron’s stifling of reform to the explosive growth at a Korean steel mill. “Provocative . . . How Asia Works is a striking and enlightening book . . . A lively mix of scholarship, reporting and polemic.” —The Economist




Mastering Cloud Computing


Book Description
