Energy Mass

Famous quotes containing the words energy and/or mass:

    Just as we are learning to value and conserve the air we breathe, the water we drink, the energy we use, we must learn to value and conserve our capacity for nurture. Otherwise, in the name of human potential we will slowly but surely erode the source of our humanity.
    Elaine Heffner (20th century)

    I am not a very sentimental man; and the best sentiment I can think of is, that if you collect the signatures of all persons who are no less distinguished than I, you will have a very undistinguishing mass of names.
    Abraham Lincoln (1809–1865)
