A critical examination of the principles and practice of qualitative research is provided in this book which examines the interplay between context and method, making it invaluable for both the experienced and the beginning researcher. A range of methodological and practical issues central to the concerns of qualitative researchers are addressed. These include: the validity and plausibility of qualitative methods; the problems encountered using specific techniques in a range of social settings; and the moral issues raised in qualitative research. These themes are related to practical issues which are illustrated by a breadth of examples and in-depth case studies. The contributors look at the methods and strategies that they have used to study everyday life, and make suggestions to readers on why and how they might conduct their own studies. They raise issues that go beyond `cookbook' discussions of issues such as how to enter social settings, manage the subjects of one's research and ask `good' questions in the process of formulating research strategies. These issues are addressed within the framework of the larger purposes and uses of qualitative research where specific methodological problems are not used as ends in themselves.

Eclipses have long been seen as important celestial phenomena, whether as omens affecting the future of kingdoms, or as useful astronomical events to help in deriving essential parameters for theories of the motion of the moon and sun. This is the first book to collect together all presently known records of timed eclipse observations and predictions from antiquity to the time of the invention of the telescope. In addition to cataloguing and assessing the accuracy of the various records, which come from regions as diverse as Ancient Mesopotamia, China, and Europe, the sources in which they are found are described in detail. Related questions such as what type of clocks were used to time the observations, how the eclipse predictions were made, and how these prediction schemes were derived from the available observations are also considered. The results of this investigation have important consequences for how we understand the relationship between observation and theory in early science and the role of astronomy in early cultures, and will be of interest to historians of science, astronomers, and ancient and medieval historians.
