"The best fuzzy rules, the best knowledge, deal with the turning points of the system. If a race-car driver teaches you how to drive, you don't need him to show you how to drive on the straightaway. It's how he handles the curves that matters."
- Bart Kosko

| A force field used to pull objects. |
Read an early example of this specialized kind of force field. This is the first instance of the term "tractor beam."
| "We'll carry off the pieces of that ship, too, Quince—we may be able to get a lot of pointers from it," and Brandon swung mighty tractor beams upon the severed halves of the Jovian vessel, then extended a couple of smaller rays to meet the two little figures racing across the smooth green meadow toward the Sirius. |

The same device is used in Triplanetary:
"What do you make of that, Costigan?" asked the captain. "Tractor beams?"
"Apparently. They've got something like that. They're taking us somewhere fast. I'll go get a couple of Standishes, and another suit of armor - we'd better dig in," - and soon the small room became a veritable fortress...
Although Smith certainly won the naming convention, Edmond Hamilton wrote about essentially the same thing three years earlier in Crashing Suns - the attractive ray.
Other examples of force fields in sf include the barrier force field fence from Robert Heinlein's 1940 novella Coventry and the force-field penknife from Isaac Asimov's 1951 novel Foundation (probably the basis for George Lucas' light saber from Star Wars).
As they entered their retreat they felt their weight begin to increase. more and more force was applied to the helpless liner until it was moving at normal acceleration.
