Before streets were brightly illuminated at night, astronomy was accessible to everyone and was a matter of great importance: for divination; for setting appropriate dates for planting, harvest, and festivals; for regulating lives. Phenomena in the heavens are still of great importance to many, and much of the lore of astronomy and astrology dates back to the earliest days of civilization. The astronomy of the ancients is thus of interest not only as history but also as the basis for much of what is known or believed about the heavens today. Because phenomena in the heavens are less familiar today than in earlier eras, this book begins with a brief description of what one can see in the sky on dark nights with the naked eye. It then turns to the astronomy of the Babylonians, who named many of our constellations, who are responsible for many of the fundamental insights of early astronomy, and who married mathematics to astronomy to make it an exact science. A chapter on Greek astronomy discusses various models of planetary motion, showing that the cycles and epicycles used by the Greeks have their modern counterparts in the computations used to compute the ephemeredes listed in the Nautical Almanac. The book then turns to a detailed discussion of Ptolemy's cosmology, the first to include quantitative models in an integral way. Though the Ptolemaic system is now often dismissed as unsound and inefficient, it is in fact a logically pleasing structure which, for more than a millennium, provided a framework for educated people throughout the Christian and Moslem worlds to think about the universe.

This book discusses in detail all the relevant numerical methods for the classical N-body problem. It demonstrates how to develop clear and elegant algorithms for models of gravitational systems, and explains the fundamental mathematical tools needed to describe the dynamics of a large number of mutually attractive particles. Particular attention is given to the techniques needed to model astrophysical phenomena such as close encounters and the dynamics of black hole binaries. The author reviews relevant work in the field and covers applications to the problems of planetary formation and star cluster dynamics, both of Pleiades type and globular clusters. Self-contained and pedagogical, this book is suitable for graduate students and researchers in theoretical physics, astronomy and cosmology.

In late 10th-century Aleppo, Al-Qabisi wrote a concise introduction to the craft of the judgements of the stars, drawing upon a wide range of Greek, Indian, Persian and Arabic sources. John of Seville's twelfth-century Latin translation led to "Alcabitius's" work becoming the standard introduction to astrology in Western Europe. This new book gives the first critical editions of the Arabic and Latin texts with an annotated English translation. It also includes: catalogues of all the manuscripts of the known medieval versions of the work and of the Renaissance editions of the Latin text; a citation of the work in Byzantine Greek; an edition of another astrological work, On the Conjunctions of the Planets, attributed in Latin to Alcabitius, and comprehensive Arabic-Latin and Latin-Arabic glossaries. This book should provide the foundation for any future study of al-Qabisi/Alcabitius and his influence.
