"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

| Emergency Repulsion (Repulsive Ray) | ||
| A beam of force that repels one object from another. |
This is the opposite of the tractor beam idea (from 'Doc' Smith's 1931 novel Space Hounds of IPC).
| Blake quite evidently was trying emergency repulsion. A faint beam of radiance streamed downward, swayed drunkenly from the tumbling movement of the falling vessel... From the side bull's-eye of the room, Georg saw the direct, actual glow of the beam as it momentarily swung downward and struck the Moon surface. |

Compare to this very similar idea, the repulsor from Frederic Brown's 1949 story What Mad Universe and the pressor beam from 'Doc' Smith's 1931 novel Space Hounds of IPC.
