Famous quotes containing the word telescope:

    The sight of a planet through a telescope is worth all the course on astronomy; the shock of the electric spark in the elbow, outvalues all the theories; the taste of the nitrous oxide, the firing of an artificial volcano, are better than volumes of chemistry.
    Ralph Waldo Emerson (1803–1882)
