From the biblical book of Genesis to Henri Bergson's Creative Evolution, these extracts from world literature illustrate the development of scientific thought across millennia. Starting with speculations by the ancient Greeks on the structure of the universe, selections on cosmogony include works by Copernicus, Galileo, Newton, Laplace, Foucault, and Einstein. Theories and reports on experimental results concerning the nature of matter range from Paracelsus' writings on alchemy to Faraday's work with electrochemistry and Sir Ernest Rutherford's studies of radioactivity and the structure of the atom. The final section on evolutionary theory begins with Aristotle and Pliny and features landmark works by the giants in the field, among them, Linnaeus, Lamarck, Lyell, Malthus, Darwin, and Mendel. 36 figures. 7 tables.
