Famous quotes containing the words bitter and/or compounds:
“To use bitter words, when kind words are at hand,
Is like picking unripe fruit when the ripe fruit is there.”
—Tiruvalluvar (c. 5th century A.D.)
“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)
