Famous quotes containing the words simple and/or compounds:
“What have Massachusetts and the North sent a few sane representatives to Congress for, of late years?... All their speeches put together and boiled down ... do not match for manly directness and force, and for simple truth, the few casual remarks of crazy John Brown on the floor of the Harper’s Ferry engine-house,—that man whom you are about to hang, to send to the other world, though not to represent you there.”
—Henry David Thoreau (1817–1862)
“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)
