Famous quotes containing the words stool and/or test:

“Most of us who turn to any subject we love remember some morning or evening hour when we got on a high stool to reach down an untried volume, or sat with parted lips listening to a new talker, or for very lack of books began to listen to the voices within, as the first traceable beginning of our love.”
—George Eliot [Mary Ann (or Marian)

“Experimental work provides the strongest evidence for scientific realism. This is not because we test hypotheses about entities. It is because entities that in principle cannot be ‘observed’ are manipulated to produce a new phenomena
[sic] and to investigate other aspects of nature.”
—Ian Hacking (b. 1936)
