A sophisticated introduction to how astronomers identify, observe, and understand black holes Emitting no radiation or any other kind of information, black holes mark the edge of the universe—both physically and in our scientific understanding. Yet astronomers have found clear evidence for the existence of black holes, employing the same tools and techniques used to explore other celestial objects. In this sophisticated introduction, leading astronomer Charles Bailyn goes behind the theory and physics of black holes to describe how astronomers are observing these enigmatic objects and developing a remarkably detailed picture of what they look like and how they interact with their surroundings. Accessible to undergraduates and others with some knowledge of introductory college-level physics, this book presents the techniques used to identify and measure the mass and spin of celestial black holes. These key measurements demonstrate the existence of two kinds of black holes, those with masses a few times that of a typical star, and those with masses comparable to whole galaxies—supermassive black holes. The book provides a detailed account of the nature, formation, and growth of both kinds of black holes. The book also describes the possibility of observing theoretically predicted phenomena such as gravitational waves, wormholes, and Hawking radiation. A cutting-edge introduction to a subject that was once on the border between physics and science fiction, this book shows how black holes are becoming routine objects of empirical scientific study.
Lieutenant Henry O. Flipper was a former slave who rose to become the first African American graduate of West Point. While serving as commissary officer at Fort Davis, Texas, in 1881, he was charged with embezzlement and conduct unbecoming an officer and a gentleman. A court-martial board acquitted Flipper of the embezzlement charge but convicted him of conduct unbecoming. He was then dismissed from the service of the United States. The Flipper case became known as something of an American Dreyfus Affair, emblematic of racism in the frontier army. Because of Flipper’s efforts to clear his name, many assumed that he had been railroaded because he was black. In The Fall of a Black Army Officer, Charles M. Robinson III challenges that assumption. In this complete revision of his earlier work, The Court-Martial of Lieutenant Henry Flipper, Robinson finds that Flipper was the author of his own problems. The taint of racism on the Flipper affair became so widely accepted that in 1999 President Bill Clinton issued a posthumous pardon for Flipper. The Fall of a Black Army Officer boldly moves the arguments regarding racism--in both Lt. Flipper’s case and the frontier army in general--beyond political correctness. Solidly grounded in archival research, it is a thorough and provocative reassessment of the Flipper affair, at last revealing the truth.

Charles Willie and Richard Reddick's A New Look at Black Families has introduced thousands of students to the intricacies of the Black family in American society since its publication in 1976. Using a case study approach, Willie and Reddick show the varieties of the Black family experience and how those experiences vary by socioeconomic status. In addition to examining families of low-income, working, and middle classes, the authors also look to the family experiences of highly successful African Americans to try to identify the elements of the family environment leading to success. The authors puncture the myth of the Black matriarchy prevalent in the popular imagination; and they explore a variety of family configurations, including a family with same-gender parents. The sixth edition has been reorganized and updated throughout. The new Part III—Cases Against and for Black Men and Women—unites two chapters from previous editions into a cohesive discussion of stereotypes and misunderstandings from both scholars and the mass media. Also, a new chapter on the Obama family offers support for cross-gender and cross-racial mentoring, and it demonstrates the value of extended family relations.
Charlie Willie's A New Look at Black Families has introduced thousands of students to the intricacies of the Black family in American society since its publication in 1976. Now, with Richard Reddick, Willie has produced a substantially-revised 5th edition of this standard text on the subject. Using a case study approach, Willie and Reddick show the varieties of the Black family experience and how those experiences vary by socioeconomic status. In addition to examining families of low-income, working, and middle classes, the authors also look to the family environment leading to success. The authors also puncture the myth of the Black matriarchy prevalent in the popular imagination.
