The Men and the Mirror
"The Men and the Mirror" is a short science fiction story by American writer Ross Rocklynne, published in Astounding Science Fiction in July 1938, since reprinted in Rocklynne's collection of the same title and in Isaac Asimov's anthology Before the Golden Age. The story is one of three stories by Rocklynne featuring the protagonist Jack Colbie of the Interplanetary Police and his pursuit of interplanetary criminal Edward Deverel.
Plot summary
In the story, Colbie and Deverel inadvertently slip onto the nearly frictionless surface of an enormous concave mirror built by unknown alien beings on Cyclops, a rogue planet recently captured into an orbit around the Sun. The two must use the laws of physics to come up with a way to avoid oscillating in a pendulum motion back and forth across the mirror until eventually the small amount of friction brings them to a stop in the center.Although the physics of the story can be criticized, the story is a textbook example of the kind of science-fiction called a "science puzzle" story, in which the set up of the story is a puzzle which must be solved using science. Later examples of this include Hal Clement's story "Dust Rag", and Larry Niven's "Neutron Star".
