Book Description
Hydrodynamics of Pumps is a reference for pump experts and a textbook for advanced students. It examines the fluid dynamics of liquid turbomachines, particularly pumps, focusing on special problems and design issues associated with the flow of liquid through a rotating machine. There are two characteristics of a liquid that lead to problems and cause a significantly different set of concerns than those in gas turbines. These are the potential for cavitation and the high density of liquids, which enhances the possibility of damaging, unsteady flows and forces. The book begins with an introduction to the subject, including cavitation, unsteady flows and turbomachinery, basic pump design and performance principles. Chapter topics include flow features, cavitation parameters and inception, bubble dynamics, cavitation effects on pump performance, and unsteady flows and vibration in pumps - discussed in the three final chapters. The book is richly illustrated and includes many practical examples.

Book Description
"[This book] deserves to be in everyone’s library. . . . It’s loaded with great information, and it can save your life or the life of someone you love."—Dr. Joseph Mercola "This book is life-changing for those trying to understand their own bodies, or those of loved ones, and it’s truly transformative in the hands of medical professionals, especially young doctors."—Foreword Reviews Thomas Cowan was a 20-year-old Duke grad—bright, skeptical, and already disillusioned with industrial capitalism—when he joined the Peace Corps in the mid-1970s for a two-year tour in Swaziland. There, he encountered the work of Rudolf Steiner and Weston A. Price—two men whose ideas would fascinate and challenge him for decades to come. Both drawn to the art of healing and repelled by the way medicine was—and continues to be—practiced in the United States, Cowan returned from Swaziland, went to medical school, and established a practice in New Hampshire and, later, San Francisco. For years, as he raised his three children, suffered the setback of divorce, and struggled with a heart condition, he remained intrigued by the work of Price and Steiner and, in particular, with Steiner’s provocative claim that the heart is not a pump. Determined to practice medicine in a way that promoted healing rather than compounded ailments, Cowan dedicated himself to understanding whether Steiner’s claim could possibly be true. And if Steiner was correct, what, then, is the heart? What is its true role in the human body? In this deeply personal, rigorous, and riveting account, Dr. Cowan offers up a daring claim: Not only was Steiner correct that the heart is not a pump, but our understanding of heart disease—with its origins in the blood vessels—is completely wrong. And this gross misunderstanding, with its attendant medications and risky surgeries, is the reason heart disease remains the most common cause of death worldwide. In Human Heart, Cosmic Heart, Dr. Thomas Cowan presents a new way of understanding the body’s most central organ. He offers a new look at what it means to be human and how we can best care for ourselves—and one another.

Book Description
Paolo Bacigalupi's debut collection demonstrates the power and reach of the science fiction short story. Social criticism, political parable, and environmental advocacy lie at the center of Paolo's work. Each of the stories herein is at once a warning, and a celebration of the tragic comedy of the human experience. The eleven stories in Pump Six represent the best Paolo's work, including the Hugo nominee "Yellow Card Man," the nebula and Hugo nominated story "The People of Sand and Slag," and the Sturgeon Award-winning story "The Calorie Man."

Book Description
Leviathan and the Air-Pump examines the conflicts over the value and propriety of experimental methods between two major seventeenth-century thinkers: Thomas Hobbes, author of the political treatise Leviathan and vehement critic of systematic experimentation in natural philosophy, and Robert Boyle, mechanical philosopher and owner of the newly invented air-pump. The issues at stake in their disputes ranged from the physical integrity of the air-pump to the intellectual integrity of the knowledge it might yield. Both Boyle and Hobbes were looking for ways of establishing knowledge that did not decay into ad hominem attacks and political division. Boyle proposed the experiment as cure. He argued that facts should be manufactured by machines like the air-pump so that gentlemen could witness the experiments and produce knowledge that everyone agreed on. Hobbes, by contrast, looked for natural law and viewed experiments as the artificial, unreliable products of an exclusive guild. The new approaches taken in Leviathan and the Air-Pump have been enormously influential on historical studies of science. Shapin and Schaffer found a moment of scientific revolution and showed how key scientific givens--facts, interpretations, experiment, truth--were fundamental to a new political order. Shapin and Schaffer were also innovative in their ethnographic approach. Attempting to understand the work habits, rituals, and social structures of a remote, unfamiliar group, they argued that politics were tied up in what scientists did, rather than what they said. Steven Shapin and Simon Schaffer use the confrontation between Hobbes and Boyle as a way of understanding what was at stake in the early history of scientific experimentation. They describe the protagonists' divergent views of natural knowledge, and situate the Hobbes-Boyle disputes within contemporary debates over the role of intellectuals in public life and the problems of social order and assent in Restoration England. In a new introduction, the authors describe how science and its social context were understood when this book was first published, and how the study of the history of science has changed since then.
