“I’ll wager that it was impossible after we got mixed together to tell an anti from a suffragist by her clothes. There might have been a difference, though, in the expression of the faces and the shape of the heads.”

“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)
