The original words announcing great scientific discoveries, from the first 'Eureka!' to the cloning of Dolly the sheep, can all be found in this fascinating new collection, a major addition to the world-famous 'Oxford Quotations' range. An essential reference tool, put together over 15 years with the assistance of a distinguished team of specialist advisers, it includes full author descriptions, exact sources, and a word-finding index for easy reference. Scholarly but accessible, it also presents the human face of science, as scientists reflect on achievements and failures in their own lives and those of others. Darwin not only describes natural selection, but carefully assesses the pros and cons of marriage, while James Clerk Maxwell constructs an electric but poetic Valentine as well as his 'demon'. From Archimedes to Einstein and beyond, the Oxford Dictionary of Scientific Quotations charts the progress of the great ideas of science.
