"If you don't care about science enough to be interested in it on its own, you shouldn't try to write hard science fiction."
- Frederik Pohl

| Barrier (Force Field) | ||
| Force-field fence. |
In this story, Heinlein explores the idea of a just society; what does that society do with people who refuse to follow the rules? People who refuse to abide by the Covenant are placed (willingly or not) in Coventry, a large area of the U.S. about the size of Montana to fend for themselves. Coventry is surrounded by an impenetrable force field called the Barrier.
| MacKinnon peered out of a forward port of the big transport helicopter with repressed excitement in his heart. There! That must be it- that black band in the distance. The helicopter drew closer, and he became certain that he was seeing the Barrier- the mysterious, impenetrable wall that divided the United States from the reservation known as Coventry...
 Barrier from 'Coventry' by Robert Heinlein) A tiny, bright dot appeared in the foot of the barrier opposite where they waited. It spread into a half circle across the lampblack nothingness. Now it was large enough for MacKinnon to see the countryside beyond through the arch it had formed. He peered eagerly. |

Another character adds:
This story is classic Heinlein; read it to get some of the basis for the socio-political climate in his future history series.
This description from Rex (1934) by Harl Vincent of a similar idea is interesting:
Compare to the Langston field from Mote in God's Eye, by Larry Niven and Jerry Pournelle.
'...I'm not a mathematical physicist, but I was always told that it was
theoretically impossible to break the Barrier-that it was just a nothingness that there was no way to
touch. Of course, you can fly over it, but even that is supposed to be deadly to life.'
Anticipating organized and armed attacks by humankind, Rex devised an invisible, impenetrable barrier of electronic vibrations which could be set up by the regular broadcast power. He caused the power plants themselves to be surrounded by these barriers, as well as providing them for the protection of the individual robots in the form of an inclosing bubble. Bulletproof, flameproof, impervious to the freezing ray of human scientists, these inclosures yet permitted each robot to carry on his newly appointed tasks without encumbrance.
