Famous quotes containing the words bitter and/or compounds:
“Sleep; and if life was bitter to thee, pardon,
If sweet, give thanks; thou hast no more to live;
And to give thanks is good, and to forgive.”
—A.C. (Algernon Charles)
“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)
