This book presents the physics of incompressible flow for the benefit of students and others who need to understand fluid motion. In this new edition, much of the material is new or rewritten, but the purpose and style of the first edition are retained. Particular emphasis is given to information obtained by experiment and observation in addition to analysis of the equations of motion. The book's primary concern is to convey a fundamental understanding of the behavior of fluids in motion. Special features include an introductory non-mathematical treatment of three particular flow configurations; extensive consideration of geophysical topics; and detailed coverage of topics that are known primarily through experimental data. Numerous photographs illustrate the phenomena discussed, and a concluding chapter demonstrates the wide applicability of fluid mechanics. New topics in the second edition include double diffusive convection and modern ideas about dynamical chaos. The discussion of instabilities has been restructured and the treatments of separation and of convection in horizontal layers considerably expanded.

Most people think of New Jersey as a suburban-industrial corridor that runs between New York and Philadelphia. Yet in the low center of the state is a near wilderness, larger than most national parks, which has been known since the seventeenth century as the Pine Barrens. The term refers to the predominant trees in the vast forests that cover the area and to the quality of the soils below, which are too sandy and acid to be good for farming. On all sides, however, developments of one kind or another have gradually moved in, so that now the central and integral forest is reduced to about a thousand square miles. Although New Jersey has the heaviest population density of any state, huge segments of the Pine Barrens remain uninhabited. The few people who dwell in the region, the “Pineys,” are little known and often misunderstood. Here McPhee uses his uncanny skills as a journalist to explore the history of the region and describe the people—and their distinctive folklore—who call it home.
