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 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. ´Schrodinger´s wave-mechanics is not a physical theory but a dodge - and a very good dodge too.´ - Arthur Eddington. ´I have little patience with scientists who take a board of wood, look for its thinnest part and drill a great number of holes where drilling is easy.´ - Albert Einstein. ´Science and everyday life cannot and should not be separated.´ - Rosalind Franklin. ´I do not feel obliged to believe that same God who has endowed us with senses, reason, and intellect has intended to forgo their use and by some other means to give us knowledge which we can attain by them.´ - Galileo Galilei. ´I try to identify myself with the atoms... I ask what I would do if I were a carbon atom or a sodium atom.´ - Linus Pauling.
