Book Description
From New York Times bestselling author Sam Kean comes incredible stories of science, history, finance, mythology, the arts, medicine, and more, as told by the Periodic Table. Why did Gandhi hate iodine (I, 53)? How did radium (Ra, 88) nearly ruin Marie Curie's reputation? And why is gallium (Ga, 31) the go-to element for laboratory pranksters? The Periodic Table is a crowning scientific achievement, but it's also a treasure trove of adventure, betrayal, and obsession. These fascinating tales follow every element on the table as they play out their parts in human history, and in the lives of the (frequently) mad scientists who discovered them. The Disappearing Spoon masterfully fuses science with the classic lore of invention, investigation, and discovery -- from the Big Bang through the end of time. Though solid at room temperature, gallium is a moldable metal that melts at 84 degrees Fahrenheit. A classic science prank is to mold gallium spoons, serve them with tea, and watch guests recoil as their utensils disappear.

Book Description
In a world where advanced knowledge is widespread and low-cost labor is readily available, U.S. advantages in the marketplace and in science and technology have begun to erode. A comprehensive and coordinated federal effort is urgently needed to bolster U.S. competitiveness and pre-eminence in these areas. This congressionally requested report by a pre-eminent committee makes four recommendations along with 20 implementation actions that federal policy-makers should take to create high-quality jobs and focus new science and technology efforts on meeting the nation's needs, especially in the area of clean, affordable energy: 1) Increase America's talent pool by vastly improving K-12 mathematics and science education; 2) Sustain and strengthen the nation's commitment to long-term basic research; 3) Develop, recruit, and retain top students, scientists, and engineers from both the U.S. and abroad; and 4) Ensure that the United States is the premier place in the world for innovation. Some actions will involve changing existing laws, while others will require financial support that would come from reallocating existing budgets or increasing them. Rising Above the Gathering Storm will be of great interest to federal and state government agencies, educators and schools, public decision makers, research sponsors, regulatory analysts, and scholars.

Book Description
This riveting work of investigative reporting and history exposes classified government projects to build gravity-defying aircraft--which have an uncanny resemblance to flying saucers. The atomic bomb was not the only project to occupy government scientists in the 1940s. Antigravity technology, originally spearheaded by scientists in Nazi Germany, was another high priority, one that still may be in effect today. Now for the first time, a reporter with an unprecedented access to key sources in the intelligence and military communities reveals suppressed evidence that tells the story of a quest for a discovery that could prove as powerful as the A-bomb. The Hunt for Zero Point explores the scientific speculation that a "zero point" of gravity exists in the universe and can be replicated here on Earth. The pressure to be the first nation to harness gravity is immense, as it means having the ability to build military planes of unlimited speed and range, along with the most deadly weaponry the world has ever seen. The ideal shape for a gravity-defying vehicle happens to be a perfect disk, making antigravity tests a possible explanation for the numerous UFO sightings of the past 50 years. Chronicling the origins of antigravity research in the world's most advanced research facility, which was operated by the Third Reich during World War II, The Hunt for Zero Point traces U.S. involvement in the project, beginning with the recruitment of former Nazi scientists after the war. Drawn from interviews with those involved with the research and who visited labs in Europe and the United States, The Hunt for Zero Point journeys to the heart of the twentieth century's most puzzling unexplained phenomena.

Book Description
Explosive, revealing, and intelligent, The Red Circle provides a uniquely personal glimpse into one of the most challenging and secretive military training courses in the world. Now including an excerpt from The Killing School: Inside the World's Deadliest Sniper Program BEFORE HE COULD FORGE A BAND OF ELITE WARRIORS... HE HAD TO BECOME ONE HIMSELF. Brandon Webb's experiences in the world's most elite sniper corps are the stuff of legend. From his grueling years of training in Naval Special Operations to his combat tours in the Persian Gulf and Afghanistan, The Red Circle provides a rare and riveting look at the inner workings of the U.S. military through the eyes of a covert operations specialist. Yet it is Webb's distinguished second career as a lead instructor for the shadowy "sniper cell" and Course Manager of the Navy SEAL Sniper Program that trained some of America's finest and deadliest warriors-including Marcus Luttrell and Chris Kyle-that makes his story so compelling. Luttrell credits Webb's training with his own survival during the ill-fated 2005 Operation Redwing in Afghanistan. Kyle went on to become the U.S. military's top marksman, with more than 150 confirmed kills. From a candid chronicle of his student days, going through the sniper course himself, to his hair-raising close calls with Taliban and al Qaeda forces in the northern Afghanistan wilderness, to his vivid account of designing new sniper standards and training some of the most accomplished snipers of the twenty-first century, Webb provides a rare look at the making of the Special Operations warriors who are at the forefront of today's military.

Book Description
From the #1 New York Times bestselling author of The Da Vinci Code, Angels & Demons, and Inferno and the “master of smart thrills” (People) comes a “rocket-fast thriller” (Vince Flynn) about an astonishing NASA discovery that unravels a deadly conspiracy that leads all the way to the White House. When a NASA satellite spots evidence of an astoundingly rare object buried deep in the Arctic ice, the floundering space agency proclaims a much-needed victory—one that could have profound implications for US space policy and the impending presidential election. With his re-election hanging in the balance, the President sends White House Intelligence analyst Rachel Sexton to the Milne Ice Shelf to verify the authenticity of the find. Accompanied by a team of experts, including the charismatic academic Michael Tolland, Rachel uncovers the unthinkable: evidence of scientific trickery. Before she can contact the President, she and Michael are attacked by a deadly team of assassins controlled by a mysterious power broker who will stop at nothing to hide the truth. Fleeing for their lives in an environment as desolate as it is lethal, their only hope for survival is to find out who is behind this masterful ploy. The truth, they will learn, is the most shocking deception of all in this “taut, fast-paced, barn-burner of a book” (St. Petersburg Times).

Book Description
In the age of automation the ability to navigate persons and devices in indoor environments has become increasingly important for a rising number of applications. However, we are still far away from achieving cheap provision of global indoor positioning with an accuracy of 1 meter or better. With the emergence of global satellite positioning systems, the performance of outdoor positioning has become excellent, but many mass market applications require seamless positioning capabilities in all environments. Therefore indoor positioning has become a focus of research and development during the past decade. This book categorizes all sighted indoor positioning approaches into 13 distinct technologies and describes the measuring principles of each. Individual approaches are characterized and key performance parameters are quantified.
