"We follow the scientists around and look over their shoulders. They're watching their feet: provable mistakes are bad for them. We're looking as far ahead as we can, and we don't get penalized for mistakes."
- Larry Niven

| Pressor (Pressor Beam) | ||
| A force-field beam that pushes, rather than pulls. |

The phrase pressor beam is also used in the same book:
We'll have them in three days, and it ought to be fairly simple to dope out the opposite of a tractor, too - a pusher or presser beam.
The opposite of a pressor beam is, of course, a tractor beam.
