Famous quotes containing the words cross and/or section:
“How have I been able to live so long outside Nature without identifying myself with it? Everything lives, moves, everything corresponds; the magnetic rays, emanating either from myself or from others, cross the limitless chain of created things unimpeded; it is a transparent network that covers the world, and its slender threads communicate themselves by degrees to the planets and stars. Captive now upon earth, I commune with the chorus of the stars who share in my joys and sorrows.”
—Gérard De Nerval (1808–1855)
“Personally I think we’re over-specialized. Why it’s getting so we have experts who concentrate only on the lower section of a specimen’s left ear.”
—Martin Berkeley, and Jack Arnold. Prof. Clete Ferguson (John Agar)
