"I share the view of Pythagoras that the world is number. The ultimate substrate of the universe is math. There's no way to test that - it's pure metaphysical speculation."
- Bart Kosko

| Centrifugal Force Creates 'Artificial Gravity' | ||
| Using centrifugal force in a rotating cylinder as a substitute for gravity. |
Very early use of this idea in science fiction.
| They entered an elevator. Three minutes later they stepped off upon the side of the great cylinder that housed the City, and entered a low building with a broad concrete road curving up before it. As they stepped out, it gave Bill a curious dizzy feeling to look up and see busy streets, inverted, a mile above his head. The road before them curved smoothly up on either hand, bordered with beautiful trees, until its ends met again above his head.
The centrifugal force that held objects against the sides of the cylinder acted in precisely the same way as gravity on the earth—except that it pulled away from the center of the cylinder, instead of toward it. |

See the entry for city of space from this same work for a more detailed discussion about artificial gravity.
For the first use of the idea see artificial gravity from Brigands of the Moon (1930) by Ray Cummings. Published the same year was the artificial gravity system from Last and First Men (1930) by Olaf Stapledon. See also paragravity from Collision Orbit (1941) by Jack Williamson.
This basic problem of space travel was recognized as early as the 17th century; see the entry for weightlessness in space from The Man in the Moone (1638), by Francis Godwin.
