Physical Tree Topology

Famous quotes containing the words physical and/or tree:

    It takes a good deal of physical courage to ride a horse. This, however, I have. I get it at about forty cents a flask, and take it as required.
    Stephen Leacock (1869–1944)

    It is, I fear, but a vain show of fulfilling the heathen precept, “Know thyself,” and too often leads to a self-estimate which will subsist in the absence of that fruit by which alone the quality of the tree is made evident.
    George Eliot [Mary Ann (or Marian)
