The weirdly alien notion of a space-time abyss from which nothing escapes-not even light-seemed to confound all logic. This engrossing book tells the story of the fierce black hole debates and the contributions of Einstein and Hawking and other leading thinkers who completely altered our view of the universe. Renowned science writer Marcia Bartusiak shows how the black hole helped revive Einstein's greatest achievement, the general theory of relativity, after decades during which it had been pushed into the shadows. Not until astronomers discovered such surprising new phenomena as neutron stars and black holes did the once-sedate universe transform into an Einsteinian cosmos, filled with sources of titanic energy that can be understood only in the light of relativity. This book celebrates the hundredth anniversary of general relativity, uncovers how the black hole really got its name, and recounts the scientists' frustrating, exhilarating, and at times humorous battles over the acceptance of one of history's most dazzling ideas.

The history of a nation-in-the-making should not be reduced to a selective heroic tradition, but should be a tolerant and continuing process of questioning and re-examintaion." Becoming Zimbabwe tracks the idea of national belonging and citizenship and explores the nature of state rule, the changing contours of the political economy, and the regional and international dimensions of the country's history. In their Introduction, Brian Raftopoulos and Alois Mlambo enlarge on these themes, and Gerald Mazarire's opening chapter sets the pre-colonial background. Sabelo Ndlovu-Gatsheni tracks the history up to World War II, and Alois Mlambo reviews developments in the settler economy and the emergence of nationalism leading to the Unilateral Declaration of Independence (UDI) in 1965. The politics and economics of the UDI period, and the subsequent war of liberation, are covered by Joseph Mtisi, Munyaradzi Nyakudya and Teresa Barnes. After independence in 1980, Zimbabwe enjoyed a period of buoyancy and hope. James Muzondidya's chapter details the transition "from buoyancy to crisis", and Brian Raftopoulos concludes the book with an analysis of the decade-long crisis and the global political agreement which followed.

In this provocative challenge to US policy and strategy, Donald Stoker argues that America endures endless wars because its leaders no longer know how to think about war, particularly limited wars. He reveals how ideas on limited war and war in general evolved against the backdrop of American conflicts in Korea, Vietnam, and Iraq. These ideas, he shows, were flawed and have undermined America's ability to understand, wage, and win its wars, and to secure peace afterwards. America's leaders have too often taken the nation to war without understanding what they want or valuing victory, leading to the 'forever wars' of today. Why America Loses Wars dismantles seventy years of misguided thinking and lays the foundations for a new approach to the wars of tomorrow. Features Summary How can you achieve victory in war if you don't know your objectives or what victory means? Donald Stoker reveals the flaws in US policy and strategy from the Korean War to the present and lays the foundations for a better approach to the wars of tomorrow.
