Physics: Imagination and Reality introduces the reader to major ideas and the conceptual structure of modern physics, by tracing its development from the introduction of fields into physics by Faraday and Maxwell in the last century. Because the approach is historical, the book provides a comprehensive overview of the subjects. It should appeal to anyone interested in a basic understanding of the contemporary physicists view of the physical world. It avoids all but the simplest mathematics and presents ideas and concepts in everyday language.Physics: Imagination and Reality attempts to provide educated citizens with an understanding of contemporary physics and, at the same time, shows that its ideas have a grandeur, a challenge to the imagination and an aesthetic appeal which merit its recognition as an integral part of our culture.

Why are prisoners horribly abused in some wars but humanely cared for in others? In Life and Death in Captivity, Geoffrey P. R. Wallace explores the profound differences in the ways captives are treated during armed conflict. Wallace focuses on the dual role played by regime type and the nature of the conflict in determining whether captor states opt for brutality or mercy. Integrating original data on prisoner treatment during the last century of interstate warfare with in-depth historical cases, Wallace demonstrates how domestic constraints and external incentives shape the fate of captured enemy combatants. Both Russia and Japan, for example, treated prisoners very differently in the Russo-Japanese War of 1904-5 and in World War II; the behavior of any given country is liable to vary from conflict to conflict and even within the same war.Democracies may be more likely to treat their captives humanely, yet this benevolence is rooted less in liberal norms of nonviolence than in concerns over public accountability. When such concerns are weak or absent, democracies are equally capable of brutal conduct toward captives. In conflicts that devolve into protracted fighting, belligerents may inflict violence against captives as part of a strategy of exploitation and to coerce the adversary into submission. When territory is at stake, prisoners are further at risk of cruel treatment as their captors seek to permanently remove the most threatening sources of opposition within newly conquered lands. By combining a rigorous strategic approach with a wide-ranging body of evidence, Wallace offers a vital contribution to the study of political violence and wartime conduct.
