Famous quotes containing the words exact and/or differential:
“Danger lies in the writer becoming the victim of his own exaggeration, losing the exact notion of sincerity, and in the end coming to despise truth itself as something too cold, too blunt for his purposeas, in fact, not good enough for his insistent emotion. From laughter and tears the descent is easy to snivelling and giggles.”
—Joseph Conrad (18571924)
“But how is one to make a scientist understand that there is something unalterably deranged about differential calculus, quantum theory, or the obscene and so inanely liturgical ordeals of the precession of the equinoxes.”
—Antonin Artaud (18961948)
