Famous quotes containing the word science:

    Nothing matters but the facts. Without them, the science of criminal investigation is nothing more than a guessing game.
    Blake Edwards (b. 1922)

    ... my one aim and concentrated purpose shall be and is to show that women can learn, can reason, can compete with men in the grand fields of literature and science ... that a woman can be a woman and a true one without having all her time engrossed by dress and society.
    M. Carey Thomas (1857–1935)

    “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)
