Famous quotes containing the words solar and/or variability:

    “Our civilization has decided ... that determining the guilt or innocence of men is a thing too important to be trusted to trained men.... When it wants a library catalogued, or the solar system discovered, or any trifle of that kind, it uses up its specialists. But when it wishes anything done which is really serious, it collects twelve of the ordinary men standing round. The same thing was done, if I remember right, by the Founder of Christianity.”
    —Gilbert Keith Chesterton (1874–1936)

    “The grand points in human nature are the same to-day they were a thousand years ago. The only variability in them is in expression, not in feature.”
    —Herman Melville (1819–1891)
