Brin, David. THE PRACTICE EFFECT, New York: Bantam Books, 1984. First edition.
Here, a physicist goes through a gate he helped build, but which is broken, to fix it. He is in another world, but he doesn't know where or when. He quickly learns that this world operates on the 'practice effect' which means that objects get better with use.
