An absorbing introduction to the growth of scientific ideas and knowledge in the last 500 years. Who Discovered What When is an absorbing introduction to the growth of scientific ideas and knowledge over the last 500 years. It sets those ideas in a context of time and place and introduces the reader to the people who brought them to life, such as Galileo, Newton, Darwin and Lavoisier. The book shows how science is a cumulative and interactive activity, with the work of one researcher feeding into that of their contemporaries and successors. It also illuminates the practice of science, briefly reviewing the methods employed and the evidence gathered in particular cases. Each chapter covers half a century and the pithy 200-300 word stories are arranged chronologically. A technology update for each century helps the reader to see the connection between scientific and technological development. Winner of the Eureka Awards for best manuscript on popular Science for the Australian Museum awards 2004.
