As demonstrated by five Nobel Prizes in physics, radio astronomy has contributed greatly to our understanding of the Universe. Courses covering this subject are, therefore, very important in the education of the next generation of scientists who will continue to explore the Cosmos. This textbook, the second of two volumes, presents an extensive introduction to the astrophysical processes that are studied in radio astronomy. Suitable for undergraduate courses on radio astronomy, it discusses the physical phenomena that give rise to radio emissions, presenting examples of astronomical objects, and illustrating how the relevant physical parameters of astronomical sources can be obtained from radio observations. Unlike other radio astronomy textbooks, this book provides students with an understanding of the background and the underlying principles, with derivations available for most of the equations used in the textbook. Features: Presents a clear and concise discussion of the important astronomical concepts and physical processes that give rise to both radio continuum and radio spectral line emission Discusses radio emissions from a variety of astronomical sources and shows how the observed emissions can be used to derive the physical properties of these sources Includes numerous examples using actual data from the literature

Moral Soundings takes a fresh new approach to introducing students and general readers to contemporary ethics. Rather than surveying the standard fare in a typical anthology format, Furrow collects diversified essays around a structured theme: does Western culture face a moral crisis of values? Prominent voices in the humanities and social sciences provide a range of perspectives on a concentrated set of ethical questions dealing with such topics as family values, the morality of capitalism, the benefits and dangers of new technologies, global conflict, and the role of religion. Unlike point/counterpoint books that often oversimplify the complexity of ethical questions, the readings in Moral Soundings provoke critical engagement and help students to recognize and emulate the logical development of arguments-all in engaging and easily accessible language. Readings are supplemented with helpful chapter introductions, study questions, and strategically placed editorial commentary to encourage further discussion and reflection. These features make Moral Soundings an ideal primary or supplementary text for undergraduate courses in ethics, contemporary moral issues, and social and political philosophy.

An in-depth examination of President Barack Obama and his policies by veteran journalist and political commentator Stanley Kurtz. How well do we really understand Barack Obama's vision for our country? In this controversial New York Times bestseller, veteran journalist and commentator Stanley Kurtz presents an exhaustively researched expose of President Obama's biggest secret-the socialist convictions and tactical ruthlessness he has long swept under the rug. Culling together two years of investigations from archives and never-before-tapped sources, Kurtz makes an in-depth exploration of the president's connections to radical groups, explains how modern "stealth" socialism continues to influence the Democratic Party, and proves that Obama's youthful infatuation with socialism was not just a phase. Those ideas have shaped his political views and set the groundwork for the long-term strategy of his administration. Eventually, in Obama's hands, capitalist America could come to resemble a socialist-inspired Scandinavian welfare state. The fears of Obama's harshest critics are justified: our Commander-in-Chief is a Radical-in-Chief. Now that we know the truth, what does it mean for our future?
