The Ozone Layer: A Philosophy Of Science Perspective

The Ozone Layer: A Philosophy of Science Perspective Maureen Christie Cambridge University Press The Ozone Layer The Ozone Layer provides the first thorough and accessible history of stratospheric ozone, from the discovery of ozone in the nineteenth century to current investigations of the Antarctic ozone hole. Drawing directly on the extensive scientific literature, Christie uses the story of ozone as a case study for examining fundamental issues relating to the collection and evaluation of evidence, the conduct of scientific debate and the construction of scientific consensus. By linking key debates in the philosophy of science to an example of real-world science the author not only provides an excellent introduction to the philosophy of science but also challenges many of its preconceptions. This accessible book will interest students and academics concerned with the history, philosophy and sociology of science, as well as having general appeal on this topic of contemporary relevance and concern.           is Lecturer in Philosophy of Science at the University of Melbourne, Australia.
