Famous quotes containing the words top and/or telescope:
“... when you make it a moral necessity for the young to dabble in all the subjects that the books on the top shelf are written about, you kill two very large birds with one stone: you satisfy precious curiosities, and you make them believe that they know as much about life as people who really know something. If college boys are solemnly advised to listen to lectures on prostitution, they will listen; and who is to blame if some time, in a less moral moment, they profit by their information?”
—Katharine Fullerton Gerould (1879–1944)
“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)
