The quote that accompanied the Word Of The Day SYZYGY was
There is hopeful symbolism in the fact that flags do not wave in a vacuum.
-Arthur C. Clarke, writer (1917- )
I've been puzzling for some time now, but I don't see this hopeful symbolism. Nationalism will not flourish in deep space? Astronauts should not carry flags? Vacuum cleaners are not bound by national borders? Help!
