Famous quotes containing the word science:
““What we know, is a point to what we do not know.” Open any recent journal of science, and weigh the problems suggested concerning Light, Heat, Electricity, Magnetism, Physiology, Geology, and judge whether the interest of natural science is likely to be soon exhausted.”
—Ralph Waldo Emerson (1803–1882)
“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)
“May we not assure ourselves that whatever woman’s thought and study shall embrace will thereby receive a new inspiration, that she will save science from materialism, and art from a gross realism; that the “eternal womanly shall lead upward and onward”?”
—Louisa Parsons Hopkins, U.S. scientist and author. As quoted in The Fair Women, ch. 16, by Jeanne Madeline Weimann (1981)
