Famous quotes containing the words acting and/or compounds:
“It is probable that the principal credit of miracles, visions, enchantments, and such extraordinary occurrences comes from the power of imagination, acting principally upon the minds of the common people, which are softer.”
—Michel de Montaigne (1533–1592)
“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)
