Kinetic Friction

Famous quotes containing the words kinetic and/or friction:

    The poem has a social effect of some kind whether or not the poet wills it to have. It has kinetic force, it sets in motion ... [ellipsis in source] elements in the reader that would otherwise be stagnant.
    Denise Levertov (b. 1923)

    We have got onto slippery ice where there is no friction and so in a certain sense the conditions are ideal, but also, just because of that, we are unable to walk. We want to walk so we need friction. Back to the rough ground!
    Ludwig Wittgenstein (1889–1951)
