"I wrote many novels which contained the element of the projected collective unconscious, which made them simply incomprehensible to anyone who read them, because they required the reader to accept my premise that each of us lives in a unique world."
- Philip K. Dick

Electromagnetic Cannon  
  A set of devices on the Ringworld used to land spacecraft safely on the fast-moving rim.  

The rim of the Ringworld grew from a dim line includinga a few stars, to a black wall. A wall a thousand miles high ... the wall sped past at a hellish 770 miles per second...

First, the ledge appeared; then, mounted on the ledge, a row of upright rings... they were no more than fifty miles across... "The cannon must have been intended for landing the ships. One can even surmise the method used. The ship must go into orbit alongside the rim wall. It will not attempt to match the ring's velocity, but will position itself twenty-five miles from the base of the rim wall. As the ring rotates, the coils of the electromagnetic cannon will scoop up the ship and accelerate it to match the velocity of the ring.

From Ringworld, by Larry Niven.
