Bubbles are everywhere—in water and in air, made from soap and from gas. They are referenced in literature and sung about in songs. They are even the subject of great works of art. From the youngest child blowing bubbles in the backyard to the adult studying the fascinating science behind them, bubbles capture our imagination. F. Ronald Young’s far-reaching survey of the humble bubble explores the complex behavior of these seemingly simple objects. If you stop to think about it, bubbles and droplets are the cornerstones of the world around us. They are the reason that dolphins cannot swim faster, that the sky is blue, and that coffee rings form. They are essential to knowing how atom smashers work, how detergents clean dishes, and how to pour a perfect pint. Beyond these basics, Young shows how humans have put bubbles to use throughout history. Whether in technology—making fire-fighting foams and waterproof makeup—or in medicine—cleaning wounds and clarifying ultrasounds—bubbles are capable of more than most of us have imagined. With easy-to-understand explanations, detailed illustrations, and entertaining anecdotes, Young reveals the Fizzics behind these familiar—yet surprising—objects.
While it is still a mystery of how a low-energy-density sound wave can concentrate enough energy in a small enough volume to cause the emission of light, research in acoustic cavitation and sonoluminescence has lead to plausible theories in which the source of light can be experimentally sustained. It has also lead to promising applications, such a
First published by McGraw-Hill in 1989, this book provides a unified treatment of cavitation, a phenomenon which extends across the boundaries of many fields. The approach is wide-ranging and the aim is to give due consideration to the many aspects of cavitation in proportion to their importance. Particular attention is paid to the diverse situations in which cavitation occurs and to its practical applications./a
Martin Luther King, Jr., is widely celebrated as an American civil rights hero. Yet King's nonviolent opposition to racism, militarism, and economic injustice had deeper roots and more radical implications than is commonly appreciated, Thomas F. Jackson argues in this searching reinterpretation of King's public ministry. Between the 1940s and the 1960s, King was influenced by and in turn reshaped the political cultures of the black freedom movement and democratic left. His vision of unfettered human rights drew on the diverse tenets of the African American social gospel, socialism, left-New Deal liberalism, Gandhian philosophy, and Popular Front internationalism. King's early leadership reached beyond southern desegregation and voting rights. As the freedom movement of the 1950s and early 1960s confronted poverty and economic reprisals, King championed trade union rights, equal job opportunities, metropolitan integration, and full employment. When the civil rights and antipoverty policies of the Johnson administration failed to deliver on the movement's goals of economic freedom for all, King demanded that the federal government guarantee jobs, income, and local power for poor people. When the Vietnam war stalled domestic liberalism, King called on the nation to abandon imperialism and become a global force for multiracial democracy and economic justice. Drawing widely on published and unpublished archival sources, Jackson explains the contexts and meanings of King's increasingly open call for "a radical redistribution of political and economic power" in American cities, the nation, and the world. The mid-1960s ghetto uprisings were in fact revolts against unemployment, powerlessness, police violence, and institutionalized racism, King argued. His final dream, a Poor People's March on Washington, aimed to mobilize Americans across racial and class lines to reverse a national cycle of urban conflict, political backlash, and policy retrenchment. King's vision of economic democracy and international human rights remains a powerful inspiration for those committed to ending racism and poverty in our time.

The lucrative international market has demonstrated a demand for American products--but it takes careful preparation to succeed in business abroad. This guide, written by the head of the Arthur Young International Management Consulting Group, shows you how to Go international in four stages: testing the waters, learning the language, mapping out a strategy, and beating overseas competitors at their own game. Supported by actual case studies, it includes sources of federal and state assistance, a directory of overseas contacts, and an overview of tax incentives and government grant and loan programs.
The artist's primary process is a dynamic color transfer technique. In preparation for each of Tillie's works, her assistant assembles a touch-sensitive recording device by affixing pigment-coated vellum to a pre-cut piece of paper backed by mat board. The artist takes the prepared canvas in her mouth and brings it to her workspace. Working on the outside surface, she applies pressure with teeth and claws in a methodic ritual marked by dramatic shifts in tempo and intensity. The resultant sharp and sweeping intersecting lines are complemented by the artist's delicate paw prints and subtle tongue impressions, composing an expressionistic image that is revealed on the paper beneath when she is finished. She works with shocking intensity, sometimes to the point of destroying her creations. Her intense, instinctive scratch marks - mostly in red, blue, yellow and black - have drawn comparisons to abstract artists Jackson Pollock and Cy Twombly.
