Bolt Circle Diameters

Famous quotes containing the words bolt and/or circle:

    My sleeping pill is white.
    It is a splendid pearl;
    it floats me out of myself,
    my stung skin as alien
    as a loose bolt of cloth.
    Anne Sexton (1928–1974)

    That three times five is equal to the half of thirty, expresses a relation between these numbers. Propositions of this kind are discoverable by the mere operation of thought, without dependence on what is any where existent in the universe. Though there never were a circle or triangle in nature, the truths, demonstrated by Euclid, would for ever retain their certainty and evidence.
    David Hume (1711–1776)
