by Bill Green (1995)
"You could die looking into such blueness," a scientist once said of Antarctica's Dry Valley lakes. Water, Ice and Stone is Bill Green's remarkable account of the time he spent probing the blueness of these lakes, expertly analyzing their chemistry and humbly listening to their stories of nature's unity. Permanently covered by as much as twelve feet of ice, these are the most isolated lakes in the world - not a single fish darts through their waters, not one tree or plant has ever taken root on their rocky shores. Yet for geologists and geochemists like Green, the lakes contain a rich historical narrative of the earth's development. In the lakes he finds answers that can be expressed in the calibrated and quantified language of research, and he finds questions that can never be answered, only pondered in the memories and musings awakened by the beauty and brutality of a lonely, dangerous land. We experience with him something of this awe and wonder - the inspiration for all scientific inquiry.

Richard A. Bauman
The study of the agenda of women in the societies of antiquity has assumed a fresh significance in recent years. This book delineates not only the influential and manipulative role of Roman women in the business of government, law and public affairs in general, but also the emergence of women's political and liberationist movements. Professor Bauman's investigation covers the period from c.350 BC to AD 68, and thus embraces the Middle and Late Republic and the Early Principate. It is demonstrated that the story of Roman women over that period is one of cohesion and continuity, of the steady expansion of women's roles in public affairs. That paced expansion, and the means by which it was achieved, such as the acquisition and use of legal knowledge and the influence of women's movements, is the central theme of this book. Bauman's treatment is principally chronological, stressing sequential development, climaxing with the Great Women of the Emperor's House. Women and Politics in Ancient Rome breaks new ground in the study of the political involvement of women in the classical age. The book will be of interest to historians, lawyers, classicists and researchers in women's studies.

Presenting powerful, proven optimization techniques for logic inference problems, Chandru and Hooker show how optimization models can be used not only to solve problems in artificial intelligence and mathematical programming, but also have tremendous application in complex systems in general. Requiring no background in logic and clearly explaining all topics from the ground up, Optimization Methods for Logical Inference is an invaluable guide for scientists and students in diverse fields, including operations research, computer science, artificial intelligence, decision support systems, and engineering.
