Famous quotes containing the words acting and/or compounds:
“We are always acting on what has just finished happening. It happened at least 1/30th of a second ago. We think we’re in the present, but we aren’t. The present we know is only a movie of the past.”
—Tom Wolfe (b. 1931)
“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)
