Famous quotes containing the words flexible, mold and/or compounds:
“Freedom is the essence of this faith. It has for its object simply to make men good and wise. Its institutions then should be as flexible as the wants of men. That form out of which the life and suitableness have departed should be as worthless in its eyes as the dead leaves that are falling around us.”
—Ralph Waldo Emerson (1803–1882)
“indolence read as abnegation,
slattern thought styled intuition,
every lapse forgiven, our crime
only to cast too bold a shadow
or smash the mold straight off.”
—Adrienne Rich (b. 1929)
“We can come up with a working definition of life, which is what we did for the Viking mission to Mars. We said we could think in terms of a large molecule made up of carbon compounds that can replicate, or make copies of itself, and metabolize food and energy. So that’s the thought: macrocolecule, metabolism, replication.”
—Cyril Ponnamperuma (b. 1923)
