Archimedes’ finding that the crown was of gold was a discovery; but he invented the method of determining the density of solids. Indeed discoverers must generally be inventors; though inventors are not necessarily discoverers. - William Ramsay 1852 to 1916 Chemist

If we attempt to we get into that paralysis of thought that comes to philosophers who sit opposite each other one saying to the other ‘You don’t know what you are talking about!’ The second one says ‘What do you mean by know? What do you mean by talking? What do you mean by you?’ and so on. ~ Richard Feynman 1918 to 1988
Although the alternate ‘wax and wane’ cycles are the rule rather than the exception in all fields of human endeavor in that of biological sciences the ‘wane’ is all too often indicative of a justified loss of faith in the rational and methodical approach that had at first raised so much hope. ~ Rita Levi-Montalcini 1909 to 2012 Neurobiologist
The invention of logarithms came to the world as a bolt from the blue. No previous work had led up to it… It stands isolated breaking in upon human thought abruptly without borrowing from the work of other intellects or following known lines of mathematical thought. ~ John Moulton 1844 – 1921 - Mathematician
