This book, in three parts, describes three phases in the development of the modern theory and calculation of the Moon's motion. Part I explains the crisis in lunar theory in the 1870s that led G.W. Hill to lay a new foundation for an analytic solution, a preliminary orbit he called the "variational curve." Part II is devoted to E.W. Brown's completion of the new theory as a series of successive perturbations of Hill's variational curve. Part III describes the revolutionary developments in time-measurement and the determination of Earth-Moon and Earth-planet distances that led to the replacement of the Hill Brown theory in 1984.

Part B of Planetary Astronomy from the Renaissance to the Rise of Astrophysics continues the history of celestial mechanics and observational discovery through the eighteenth and nineteenth centuries. It provides a synoptic view of the main developments and furnishes details about the lives, ideas, and interactions of the various astronomers involved. Twelve different authors have contributed their expertise to this book that begins with the reception of Newton's inverse-square law. In the remainder, a large place is given to the development of the mathematical theory of celestial mechanics from Clairaut and Euler to LeVerrier, Newcomb, Hill, and Poincare. This emphasis is balanced by other chapters on observational discoveries and the rapprochement of observation and theory (for instance, the discovery of Uranus and the asteroids, use of Venus transits to refine solar parallax, introduction of the method of least squares, and the development of planetary and satellite ephemerides). Lists of "Further Reading" provide entree to the literature of the several topics. This book will be of great interest to historians of science and astronomers.

In this book FranA ois De Gandt introduces us to the reading of Newton's "Principia" in its own terms. The path of access that De Gandt proposes leads through the study of the geometrization of force. The result is a highly original meditation on the sources and meaning of Newton's "magnum opus."

In Chapter I De Gandt presents a translation of and detailed commentary on an earlier and simpler version of what in 1687 became Book I of the "Principia"; here in clearer and starker outline than in the final version, the basic principles of Newton's dynamics show forth. Chapter II places this dynamics in the intellectual context of earlier efforts--the first seeds of celestial dynamics in Kepler, Galileo's theory of accelerated motion, and Huygens's quantification of centrifugal force--and evaluates Newton's debt to these thinkers. Chapter III is a study of the mathematical tools used by Newton and their intellectual antecedents in the works of Galileo, Torricelli, Barrow, and other seventeenth-century mathematicians. The conclusion discusses the new status of force and cause in the science that emerges from Newton's "Principia."

The story of Irish linen is a story of the Irish people. Many thousands of men and women made Irish linen a global product and an international brand. It is also a story of innovation and opportunity. Irish linen has served its makers as sail cloth of incredible strength and durability for world exploration; it has functioned as watertight containers for farmers and firemen; it has soothed the brows of royalty and absorbed the sweat of the working class. As outerwear and underwear, linen has covered the bodies of men, women, and children from birth to death--the rich and powerful, poor and pitiful alike. Into this cultural history, Kathleen Curtis Wilson weaves personal narratives, giving the story a voice: words and songs of individual spinners, factory workers, and out-workers like Sarah McCabe, who created fabulous linen lace; Sarah Leech, who wrote poetry as she spun fine thread; the three Patterson women, who worked in Mossley Mill for a total of one hundred years; and the Herdman brothers, who settled in County Tyrone to build a mill and a utopian community. Lavishly illustrated and engagingly written, each chapter tells of art, social and economic history, design, architecture, technology, and cultural traditions that celebrate the industry of making linen, a highly useful and desirable commodity that helped transport Irish people across the Atlantic to influence the settling of North America.
