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.
Ronald L. Godbee, Sr. calls it “the book that will liberate you and activate you to live from the position that Christ established for you on the cross.” While many think that the difference between poverty and wealth is defined by the car one drives, the size of the house one lives in and the amount of money in one’s bank account, the truth of the matter is those things are results—or lack thereof—not definitions. In this candid debut book, Breaking the Chains of Poverty: The Secret to Having a Wealthy, Healthy and Wholesome Life, author Demetrius Sandridge helps readers recognize those moments God affords us the opportunity to prosper and come up higher in every aspect of our lives—and how we can maximize those opportunities. Chronicling his story from rags to riches, and riches back to rags, Sandridge ignites a sense of excitement and urgency—which catapults readers out of a poverty mindset into a millionaire mentality with every turn of the page. In this book, you will be challenged to: • Transform your mindset to that of a millionaire • Learn to use money as a tool, not a motivator of dreams and goals • Apply simplistic, practical approaches to go from your current reality to dream fulfillment • How to apply action to your faith, and faith to your actions • Encourage others to adopt your new way of thinking • And more!

The selection and application of engineered materials is an integrated process that requires an understanding of the interaction between materials properties, manufacturing characteristics, design considerations, and the total life cycle of the product. This reference book on engineering plastics provides practical and comprehensive coverage on how the performance of plastics is characterized during design, property testing, and failure analysis. The fundamental structure and properties of plastics are reviewed for general reference, and detailed articles describe the important design factors, properties, and failure mechanisms of plastics. The effects of composition, processing, and structure are detailed in articles on the physical, chemical, thermal, and mechanical properties. Other articles cover failure mechanisms such as: crazing and fracture; impact loading; fatigue failure; wear failures, moisture related failure; organic chemical related failure; photolytic degradation; and microbial degradation. Characterization of plastics in failure analysis is described with additional articles on analysis of structure, surface analysis, and fractography.
This book is a panoramic view of nature, from quarks to the edge of the universe. It holds this wide range of topics together by addressing the question how big are things and why are they that size. The book is full of curios as well as interesting facts and unique descriptions of dozens of things in the universe.
