Famous quotes containing the words solar and/or variability:

    “Senta: These boats, sir, what are they for?
    Hamar: They are solar boats for Pharaoh to use after his death. They’re the means by which Pharaoh will journey across the skies with the sun, with the god Horus. Each day they will sail from east to west, and each night Pharaoh will return to the east by the river which runs underneath the earth.”
    —William Faulkner (1897–1962)

    “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)
