Famous quotes containing the words experiments and/or rays:

    A country survives its legislation. That truth should not comfort the conservative nor depress the radical. For it means that public policy can enlarge its scope and increase its audacity, can try big experiments without trembling too much over the result. This nation could enter upon the most radical experiments and could afford to fail in them.
    Walter Lippmann (1889–1974)

    Beneath the sun’s rays our shadow is our comrade;
    When clouds obscure the sun our shadow flees.
    So Fortune’s smiles the fickle crowd pursues,
    But swift is gone whenever she veils her face.
    Ovid (Publius Ovidius Naso)
