The Practice Effect is a novel by David Brin, written in 1984.

Plot summary

A scientist by the name of Dennis Nuel is working at, and attending, an institute of scientific research and pioneering work into the fictional scientific field of "Zievatronics", the manipulation of Time and Space. After the death of his mentor, however, he is taken off the project and another professor takes over. After a time, the device that has been created to move through space and time, known as the "Zievatron" encounters operational problems and is fixed to the co-ordinates of a world that appears to be very similar to our Earth in most respects, and Dennis is re-recruited to help fix it. He volunteers to be sent to the other world in order to fix the other part of the Zievatron. On arriving to this planet, he finds the Zievatron dismantled and critical parts of it missing. Of the 3 surveillance robots that were sent through to this planet, he finds 2 that have also been broken apart. After a while, he finds the last robot, intact and still functioning, and uses it to view any recorded images that might help him identify what it was that happened to the Zievatron.In this world, instead of objects wearing out as you use them, they improve. This is referred to as the Practice effect. For example, swords get sharper with use, baskets get stronger the more things they carry, mirrors, furniture and decorations look more attractive the more they are looked at. The downside to this being that an object's condition deteriorates over time if not put to use. Under this system, members of society's higher strata employ servants to Practice their own possessions to perfection. It is eventually discovered that the Practice Effect is the result of an elusive, biologically engineered creature known as a Krenegee Beast that causes a change in a law of Thermodynamics. This creature emits a field under which the Practice Effect works. The closer one is to the Krenegee Beasts, the more efficient the Practice that is done. The Practice Effect can take many months before an object reaches its maximum point of "practice" however if one is under a Felthesh Trance the process is sped up if a Krenegee Beast is present the process is sped up more so than if one were under a Felthesh Trance.

Weird Physics!
This is a rather tongue in cheek science fiction story.  It is not very serious.  In fact it is quite often hilarious.  The physics in the story is almost certainly impossible anywhere in the universe.  But it can make one think about how the way physics works makes reality what it is.  If it worked a different way it would be a different reality.      Suppose that as you used an ax to chop down trees it got sharper.  But if you stuck it in a drawer …
