This account of the Khobar Towers bombing tells the story of the horrific attack and the magnificent response of airmen doing their duty under nearly impossible circumstances. None of them view their actions as heroic, yet the reader will marvel at their calm professionalism. All of them say it was just their job, but the reader will wonder how they could be so well trained to act almost instinctively to do the right thing at the right time. None of them would see their actions as selfless, yet countless numbers refused medical attention until the more seriously injured got treatment. Throughout this book, the themes of duty, commitment, and devotion to comrades resoundingly underscore the notion that America's brightest, bravest, and best wear her uniforms in service to the nation. This book is more than heroic actions, though, for there is also controversy. Were commanders responsible for not adequately protecting their people? What should one make of the several conflicting investigations following the attack? Dr. Jamieson has not shied away from these difficult questions, and others, but has discussed them and other controversial judgments in a straightforward and dispassionate way that will bring them into focus for everyone. It is clear from this book that there is a larger issue than just the response to the bombing. It is the issue of the example set by America's airmen. Future airmen who read this book will be stronger and will stand on the shoulders of those who suffered and those who made the ultimate sacrifice.

This book deals with the general concepts in stereotomy and its connection with descriptive geometry, the social background of its practitioners and theoreticians, the general methods and tools of this technology, and the specific procedures for the members built in hewn stone, including arches, squinches, stairs and vaults, ending with a chapter discussing the open problems in this field. Thus, it can be used as a reference book in the subject, but it can also read as a compelling narrative on this subject, one of the main branches of pre-industrial technology. Construction in hewn stone requires the use of geometrical methods and tools to assure that individual stones, either blocks or voussoirs, fit with one another and conform to the general shape of walls, arches or vaults. During the Late Middle Ages and the Renaissance, such techniques and instruments were developed empirically by masons and architects. Later on, learned mathematicians and engineers introduced refinements in these procedures and this branch of knowledge, known as stereotomy, furnished much material to descriptive geometry, a science born with the French Revolution which provided the foundation for projective geometry.

Before Palm Pilots and iPods, PCs and laptops, the term "computer" referred to the people who did scientific calculations by hand. These workers were neither calculating geniuses nor idiot savants but knowledgeable people who, in other circumstances, might have become scientists in their own right. When Computers Were Human represents the first in-depth account of this little-known, 200-year epoch in the history of science and technology. Beginning with the story of his own grandmother, who was trained as a human computer, David Alan Grier provides a poignant introduction to the wider world of women and men who did the hard computational labor of science. His grandmother's casual remark, "I wish I'd used my calculus," hinted at a career deferred and an education forgotten, a secret life unappreciated; like many highly educated women of her generation, she studied to become a human computer because nothing else would offer her a place in the scientific world. The book begins with the return of Halley's comet in 1758 and the effort of three French astronomers to compute its orbit. It ends four cycles later, with a UNIVAC electronic computer projecting the 1986 orbit. In between, Grier tells us about the surveyors of the French Revolution, describes the calculating machines of Charles Babbage, and guides the reader through the Great Depression to marvel at the giant computing room of the Works Progress Administration. When Computers Were Human is the sad but lyrical story of workers who gladly did the hard labor of research calculation in the hope that they might be part of the scientific community. In the end, they were rewarded by a new electronic machine that took the place and the name of those who were, once, the computers.
