(A science fiction short story.) Time travel is real. The trick is to figure out how to do it without a machine--that will take too long, and the physicist in charge of coming up with the solution is running out of time. His wife will die if he can't unlock the secret to traveling backward and undoing what has happened. So why is he fishing instead of working on the problem? Because sometimes a few days in the wilderness might be just what you need to understand the mysteries of quantum physics.
