Book Description
This volume from The NASA History Series presents an overview of the science of hypersonics, the study of flight at speeds at which the physics of flows is dominated by aerodynamic heating. The survey begins during the years immediately following World War II, with the first steps in hypersonic research: the development of missile nose cones and the X-15; the earliest concepts of hypersonic propulsion; and the origin of the scramjet engine. Next, it addresses the re-entry problem, which came to the forefront during the mid-1950s, showing how work in this area supported the manned space program and contributed to the development of the orbital shuttle. Subsequent chapters explore the fading of scramjet studies and the rise of the National Aerospace Plane (NASP) program of 1985–95, which sought to lay groundwork for single-stage vehicles. The program's ultimate shortcomings — in terms of aerodynamics, propulsion, and materials — are discussed, and the book concludes with a look at hypersonics in the post-NASP era, including the development of the X-33 and X-34 launch vehicles, further uses for scramjets, and advances in fluid mechanics. Clearly, ongoing research in hypersonics has yet to reach its full potential, and readers with an interest in aeronautics and astronautics will find this book a fascinating exploration of the field's history and future.

Book Description
From the "preeminent historian of Reconstruction" (New York Times Book Review), a newly updated edition of the prize-winning classic work on the post-Civil War period which shaped modern America, with a new introduction from the author. Eric Foner's "masterful treatment of one of the most complex periods of American history" (New Republic) redefined how the post-Civil War period was viewed. Reconstruction chronicles the way in which Americans—black and white—responded to the unprecedented changes unleashed by the war and the end of slavery. It addresses the ways in which the emancipated slaves' quest for economic autonomy and equal citizenship shaped the political agenda of Reconstruction; the remodeling of Southern society and the place of planters, merchants, and small farmers within it; the evolution of racial attitudes and patterns of race relations; and the emergence of a national state possessing vastly expanded authority and committed, for a time, to the principle of equal rights for all Americans. This "smart book of enormous strengths" (Boston Globe) remains the standard work on the wrenching post-Civil War period—an era whose legacy still reverberates in the United States today.

Book Description
Varian Fry, a young editor from New York, traveled to Marseilles after Germany defeated France in the summer of 1940. As the representative of the Emergency Rescue Committee, a private American relief organization, he offered aid and advice to refugees who found themselves threatened with extradition to Nazi Germany under Article 19 of the Franco-German armistice — the “Surrender on Demand” clause. Fry risked his life to rescue those targeted by the Gestapo in “the most gigantic man-trap in history.” Working day and night with a few associates in opposition to France’s Vichy government and to American authorities, his elaborate rescue network managed to spirit more than 1,500 people — including prominent European politicians, artists, writers and scientists — to safety by the time Fry was expelled from France after 13 months. “Surrender on Demand is by turns wildly exciting, horrifying and exalting. Certainly, there has never been another book like it... Varian Fry is a good man. Through the people he has helped rescue — the doctors, the painters, the writers, the sculptors, the teachers — he has added to the sum total of the world’s happiness... an astonishingly good book.” — Russell Maloney, The New York Times “Surrender on Demand contains enough intrigue and conspiracy, enough narrow escapes and shady and flamboyant characters for three or four spy stories. But Mr. Fry has not written it for excitement... He has put down some plain and eloquent facts.” — Orville Prescott, The New York Times “I have read and heard many accounts of escapes from Europe... but none surpasses this restrained and factual narrative in suspense and excitement... It tells of many triumphs and some defeats: it depicts with vividness and often with humor a large number of interesting and frequently distinguished persons; it describes the endless obstacles encountered and the ingenious and constantly changing shifts and devices contrived to overcome them; and throughout it makes one feel the undercurrent of potential tragedy which too often became actual.” — New York Herald Tribune Weekly Book Review “A novelist would hardly dare pack a novel with so many hair-breath escapes.” — Lewis Gannett, New York Herald Tribune “... a brilliant exposé of the work accomplished by [Fry] in Marseille during the tragic days that followed the French defeat... Surrender on Demand is a unique contribution to the underground history of the war.” — Josef Forman, Free World “There are a larger number of highly exciting and almost unbelievable stories in this deeply moving but often also highly amusing book. Friends of light adventure novels will undoubtedly like it. And friends of humanity will see much more in it than an adventure story although it deals with forging passports, with hiding and escaping from detectives, with secret messages hidden in a toothpaste tube, and with an underground railroad over a well protected border. They will see in it a memorial to the man who made what he modestly calls ‘an experiment in democratic solidarity’ and also to the women and men who sent him on his dangerous mission.” — Henry B. Kranz, Saturday Review
