"In a groundbreaking book based on six years of reporting, leading expert on humanitarian aid and development David Rieff offers a review of whether the end of extreme poverty and widespread hunger are within our reach. Some of the most brilliant scientists, world politicians, and development experts agree that the eradication of hunger is an essential task for the new millennium. Yet in the last decade, the prices of wheat, soy and rice have soared. This has condemned the hundreds of millions of the world's population who live on less than one dollar per day to a state of hunger and insecurity. Rieff searches for the causes of this food security crisis, as well as what lies behind the failures to respond to disaster: failures to address climate change, poor governance, and misguided optimism. Rieff cautions against the increased privatization of aid, as well as the interventions of celebrity campaigners, whose business-led solutions rob development of political urgency. He dismisses the idle hope of Bill Gates and Warren Buffett that food scarcity can be solved by technological innovation alone. The path ahead, Rieff reminds us, demands we rethink the fundamental causes of the world's grotesque inequalities and understand that what is at stake is a political challenge we are failing to confront".

A great mathematician and teacher bridges the gap between science and the humanities in this exposition of the philosophy of science. Philipp Frank, a distinguished physicist and philosopher in his own right, traces the history of science from Aristotle to Einstein to illustrate philosophy’s ongoing role in the scientific process. Suitable for undergraduate students and other readers, this volume explains modern technology’s role in the gradual erosion of the rapport between physical theories and philosophical systems, and offers suggestions for restoring the link between these related areas. Dr. Frank examines the ancient Greek concept of natural science to illustrate the development of modern science; then, using geometry as an example, he charts its progress from Euclidean principles through the interpretations of Descartes, Mill, Kant, and the rise of four-dimensional and non-Euclidean geometry. Additional topics include the laws of motion, before and after innovations of Galileo and Newton; perceptions of motion, light, and relativity through the ages; metaphysical interpretations of relativistic physics; the motion of atomic objects and the phenomena and formulations of atomic physics; and the principle of causality and the validation of theories.
