Ray Tracing

Famous quotes containing the words ray and/or tracing:

    Colleges, in like manner, have their indispensable office,—to teach elements. But they can only highly serve us, when they aim not to drill, but to create; when they gather from far every ray of various genius to their hospitable halls, and, by the concentrated fires, set the hearts of their youth on flame.
    Ralph Waldo Emerson (1803–1882)

    In mind, she was of a strong and vigorous turn, having from her earliest youth devoted herself with uncommon ardour to the study of the law; not wasting her speculations upon its eagle flights, which are rare, but tracing it attentively through all the slippery and eel-like crawlings in which it commonly pursues its way.
    Charles Dickens (1812–1870)
