A neighbor of mine recently asked me to review a manuscript of a mid grade science fiction novel with an eye toward the world building in the story. I’m not an expert by any means, but I have read a lot of science fiction over the course of my life and I’m always willing to offer my opinions regardless of how well or ill founded they may be. My wife saw part of what I wrote and thought it might make a good blog post. It was on the difference between magic and science fiction.
One of the things I included in my ramblings was a favorite aphorism coined by Arthur C. Clarke a famous science fiction author and scientist in his own right: “Any sufficiently advanced technology is indistinguishable from magic.” So the difference between a fairy tale and science fiction is changing the label from “magic” to “science.”
