Famous quotes containing the word science:
“The knowledge of an unlearned man is living and luxuriant like a forest, but covered with mosses and lichens and for the most part inaccessible and going to waste; the knowledge of the man of science is like timber collected in yards for public works, which still supports a green sprout here and there, but even this is liable to dry rot.”
—Henry David Thoreau (1817–1862)
“Hard times accounted in large part for the fact that the exposition was a financial disappointment in its first year, but Sally Rand and her fan dancers accomplished what applied science had failed to do, and the exposition closed in 1934 with a net profit, which was donated to participating cultural institutions, excluding Sally Rand.”
—For the State of Illinois, U.S. public relief program (1935-1943)
