"Every scientist worth his salt that I know of has read science fiction."

| Pressor Field | ||
| A force field that pressed against anything that encountered it. |
| I later learned that the city sprawled out over 200 square kilometers, that you could take a subway to anyplace that was too far to walk. The ecology of Threshold was very carefully balanced and maintained so as to resemble the jungle outside with all the dangerous and uncomfortable elements eliminated. A powerful pressor field kept out large predators and such insect life as was not necessary for the health of the plants inside. |

As far as I know, the first reference to such a field was the pressor beam from Gray Lensman, the 1942 novel by E.E. 'Doc' Smith.
A similar idea for a similar purpose is the sonabarrier from Frank Herbert's 1977 novel The Dosadi Experiment.
