"You have to budget the number of fuzzy rules you use to control a system. It turns out, you can state the optimality principle in three words: 'patch the bumps.'"
- Bart Kosko

| Bat Wings | ||
| The dream of human-powered winged flight becomes a reality - in low gravity, of course. |
In this excerpt from the novel, the inhabitants of an orbiting habitat take time for recreation.
| There were wings attached to hooks at the entrance. McLeve took down a set and began strapping them on. Black bat wings. They made him look like a fallen angel, Milton's style. He handed me another pair. "Like to fly?" he asked... I was a tiny chick in a vast eggshell. The landscape was wrapped around me: fields and houses... Every direction was down. |

This is from Spirals a short story by Niven and Jerry Pournelle.
Hang gliding is a similar sport; it gained popularity in the late 1960's and early 1970's. Hang gliding is based on a technology developed in 1948 called the "parawing", a
V-shaped flexible airfoil made of fabric. NASA showed early interest in using it for returning space craft.
As alert readers have pointed out, Robert Heinlein originated this idea almost thirty years earlier in The Menace From Earth - see the entry for Bat's Wings. For a different take on this idea, see the Dragonfly sky-bike from Rendezvous With Rama (1972) by Arthur C. Clarke.
