From Arthur C. Clarke's Preface to Reach for Tomorrow: "Time's Arrow is an example of how hard it is for the science-fiction writer to keep ahead of fact. The quite -- at the time the story was written -- imaginary discovery described in the tale now actually exists, and may be seen in the New York Natural History Museum."
