Germaine Greer 73
Australian feminist author 1939Related quotes

Misattributed to Kelvin since the 1980s, either without citation or stating that it was made in an address to the British Association for the Advancement of Science in 1900. There is no evidence that Kelvin said this, and the quote is instead a paraphrase of Albert A. Michelson, who in 1894 stated: "… it seems probable that most of the grand underlying principles have been firmly established … An eminent physicist remarked that the future truths of physical science are to be looked for in the sixth place of decimals." The attribution to Kelvin giving an address in 1900 is presumably a confusion with his “Two clouds” speech, delivered to the Royal Society in 1900 (see above), and which on the contrary pointed out areas that would subsequently see revolutions.

“Measure what is measurable, and make measurable what is not so.”
The quote is widely misattributed to Galilei, but is actually from two French scholars, Antoine-Augustin Cournot and Thomas-Henri Martin.
