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.

An author writes a book, and that's the book at that point. And if the author writes the book again, then somehow something has gone wrong, if you see what I mean.

When you read, I'm sure you don't realize that your eyes are going backwards and forwards and to this place and that place. Mine don't do that.
