Modern science has developed in three major phases: the Scientific Revolution; the rise of geology and Darwin's theory of evolution; and the natural sciences of the 20th century.Surveying the key developments in the natural sciences over the past 450 years, this text provides an outline of the present science and theology discourse and suggests how a scientific description of the world may be placed within a broad theistic theme. The first two phases are described through the work of leading ecientific figures, from Copernicus to Newton, and from Linnaeus to Darwin.
