It cannot be said often enough that science fiction as a genre is incredibly educational - and I'm speaking the written science fiction not 'Star Trek.' Science fiction writers tend to fill their books if they're clever with little bits of interesting stuff and real stuff.
There are accents in the eye which are not on the tongue, and more tales come from pale lips than can enter an ear. It is both the grandeur and the pain of the remoter moods that they avoid the pathway of sound.
