Famous quotes containing the words bitter and/or compounds:
“For this your mother sweated in the cold,
For this you bled upon the bitter tree:
A yard of tinsel ribbon bought and sold;
A paper wreath; a day at home for me.”
—Edna St. Vincent Millay (1892–1950)
“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)
