The incredible story of spaceflight before the establishment of NASA. NASA's history is a familiar story, one that typically peaks with Neil Armstrong taking his small step on the Moon in 1969. But America's space agency wasn't created in a vacuum. It was assembled from pre-existing parts, drawing together some of the best minds the non-Soviet world had to offer. In the 1930s, rockets were all the rage in Germany, the focus both of scientists hoping to fly into space and of the German armed forces, looking to circumvent the restrictions of the Treaty of Versailles. One of the key figures in this period was Wernher von Braun, an engineer who designed the rockets that became the devastating V-2. As the war came to its chaotic conclusion, von Braun escaped from the ruins of Nazi Germany, and was taken to America where he began developing missiles for the US Army. Meanwhile, the US Air Force was looking ahead to a time when men would fly in space, and test pilots like Neil Armstrong were flying cutting-edge, rocket-powered aircraft in the thin upper atmosphere. Breaking the Chains of Gravity tells the story of America's nascent space program, its scientific advances, its personalities and the rivalries it caused between the various arms of the US military. At this point getting a man in space became a national imperative, leading to the creation of the National Aeronautics and Space Administration, otherwise known as NASA.

Cy Williams, thirteen, has always known that he and the other black folks on Strong's plantation have to obey white men, no question. Sure, he's free, as black people have been since his grandfather's day, but in rural Georgia, that means they're free to be whipped, abused, even killed. Almost four years later, Cy yearns for that freedom, such as it was. Now he's a chain gang laborer, forced to do backbreaking work, penned in and shackled like an animal, brutalized, beaten, and humiliated bythe boss of the camp and his hired overseers. For Cy and the boys he's chained to, there's no way out, no way back. And then hope begins to grow in him, along with strength and courage he didn't know he had. Cy is sure that a chance at freedom is worth any risk, any sacrifice. This powerful, moving story opens a window on a painful chapter in the history of race relations.

Spaceflight historian Amy Shira Teitel tells the riveting story of the female pilots who each dreamed of being the first American woman in space. When the space age dawned in the late 1950s, Jackie Cochran held more propeller and jet flying records than any pilot of the twentieth century—man or woman. She had led the Women's Auxiliary Service Pilots during the Second World War, was the first woman to break the sound barrier, ran her own luxury cosmetics company, and counted multiple presidents among her personal friends. She was more qualified than any woman in the world to make the leap from atmosphere to orbit. Yet it was Jerrie Cobb, twenty-five years Jackie's junior and a record-holding pilot in her own right, who finagled her way into taking the same medical tests as the Mercury astronauts. The prospect of flying in space quickly became her obsession. While the American and international media spun the shocking story of a "woman astronaut" program, Jackie and Jerrie struggled to gain control of the narrative, each hoping to turn the rumored program into their own ideal reality—an issue that ultimately went all the way to Congress. This dual biography of audacious trailblazers Jackie Cochran and Jerrie Cobb presents these fascinating and fearless women in all their glory and grit, using their stories as guides through the shifting social, political, and technical landscape of the time.
This book covers the classical theory of Markov chains on general state-spaces as well as many recent developments. The theoretical results are illustrated by simple examples, many of which are taken from Markov Chain Monte Carlo methods. The book is self-contained, while all the results are carefully and concisely proven. Bibliographical notes are added at the end of each chapter to provide an overview of the literature. Part I lays the foundations of the theory of Markov chain on general states-space. Part II covers the basic theory of irreducible Markov chains on general states-space, relying heavily on regeneration techniques. These two parts can serve as a text on general state-space applied Markov chain theory. Although the choice of topics is quite different from what is usually covered, where most of the emphasis is put on countable state space, a graduate student should be able to read almost all these developments without any mathematical background deeper than that needed to study countable state space (very little measure theory is required). Part III covers advanced topics on the theory of irreducible Markov chains. The emphasis is on geometric and subgeometric convergence rates and also on computable bounds. Some results appeared for a first time in a book and others are original. Part IV are selected topics on Markov chains, covering mostly hot recent developments.
