Famous quotes containing the word science:

    The natural historian is not a fisherman who prays for cloudy days and good luck merely; but as fishing has been styled “a contemplative man’s recreation,” introducing him profitably to woods and water, so the fruit of the naturalist’s observations is not in new genera or species, but in new contemplations still, and science is only a more contemplative man’s recreation.
    Henry David Thoreau (1817–1862)

    Science is facts. Just as houses are made of stones, so is science made of facts. But a pile of stones is not a house and a collection of facts is not necessarily science.
    Jules Henri Poincare (1854–1912)

    There is a chasm between knowledge and ignorance which the arches of science can never span.
    Henry David Thoreau (1817–1862)
