Gravitational Lens/explanation in Terms of Space-time Curvature

Famous quotes containing the words explanation and/or terms:

    There is no explanation for evil. It must be looked upon as a necessary part of the order of the universe. To ignore it is childish, to bewail it senseless.
    W. Somerset Maugham (1874–1965)

    The research on gender and morality shows that women and men looked at the world through very different moral frameworks. Men tend to think in terms of “justice” or absolute “right and wrong,” while women define morality through the filter of how relationships will be affected. Given these basic differences, why would men and women suddenly agree about disciplining children?
    Ron Taffel (20th century)
