"It was my preferred entertainment when I was a kid, so when I set out to be a writer, it was perfectly natural that I should write the sort of stories that I used to enjoy reading."

| Gravity Neutralizing Disks | ||
| Two plates between which Earth's gravitational influence is cancelled out. |
These gravity neutralizing disks are necessary for Fessenden's creation of a miniature universe in his lab.
| It consisted of two twelve-foot metal disks with grid-like surfaces, one on the floor and one on the ceiling directly over the other. They were connected by cables to the electrical machinery, and their grid-like surfaces shone faintly with wan blue light or force.
Fessenden walked over to the thing and motioned calmly toward the blue-glowing disks in floor and ceiling. These disks, Bradley, neutralize all the ordinary gravitational forces of earth in the space between them. "What?" I cried, astonished. I stepped forward, was about to thrust my hand between the two disks to test the assertion. But Fessenden held me back. "Don't try that," he warned. "The human body is accustomed to earth's gravitation, and is inwardly braced against it. If you were to step between those disks, out of earth's gravitation, your body would explode from its own inward pressure..." |

Hamilton was something of a child prodigy; he started college at 14, but quit three years later. If he had stayed in a bit longer, he might have been able to distinguish between the force of gravity and the force applied to our bodies by air pressure.
This is an interesting predecessor to the sleeping plates that Larry Niven wrote about.

Technovelgy (that's tech-novel-gee!) is devoted to the creative science inventions and ideas of sf authors. Look for the Invention Category that interests you, the Glossary, the Invention Timeline, or see what's New.

'A worker replaced by a nubot... had to be compensated.'
'... forcing the energy transfer which allowed him to regrow his lost fingers.'
'The car surged and lifted, clearing its top by a negligible margin.'
Science fiction authors are serious about sleep, too.
'I had explained," said Nessus, "that our civilisation was dying in its own waste heat.'
'Just what did I want Flexible Frank to do? - any work a human being does around a house.'
SF writers have thought about this since the 19th century.
