Never has the power of scientific research to solve existing problems and uncover new ones been more evident than it is today. Yet there exists widespread ignorance about the larger contexts within which scientific research is carried out. For example, the point of view some scientists adopt in their work or in their social commitments may become clearer if considered in light of the opposing views held by other scientists.

This is a theme Gerald Holton addresses in his new collection. Whether considering conflicts between Heisenberg and Einstein, Bohr and Einstein, or P. W. Bridgman and B. F. Skinner; tracing I. I. Rabi's shift of attention from superb science to education and scientific statesmanship; or examining the emergence, in the last few decades, of the need to connect scientific research to societal needs--in each case, Holton demonstrates a masterly understanding of modern science and how it influences our world.

The author shows why, at any given time--even in the mature phase of science--there exists no single "paradigm," but rather a spectrum of competing perspectives; and why so much good science has been based, from antiquity to today, on a relatively small number of presuppositions.

Scientists have identified southern China as a likely epicenter for viral pandemics, a place where new viruses emerge out of intensively farmed landscapes and human--animal interactions. In Virulent Zones, Lyle Fearnley documents the global plans to stop the next influenza pandemic at its source, accompanying virologists and veterinarians as they track lethal viruses to China's largest freshwater lake, Poyang Lake. Revealing how scientific research and expert agency operate outside the laboratory, he shows that the search for origins is less a linear process of discovery than a constant displacement toward new questions about cause and context. As scientists strive to understand the environments from which the influenza virus emerges, the unexpected scale of duck farming systems and unusual practices such as breeding wild geese unsettle research objects, push scientific inquiry in new directions, and throw expert authority into question. Drawing on fieldwork with global health scientists, state-employed veterinarians, and poultry farmers in Beijing and at Poyang Lake, Fearnley situates the production of ecological facts about disease emergence inside the shifting cultural landscapes of agrarian change and the geopolitics of global health.
