"Science and science fiction, how do you even distinguish the two?"
- Jerry Pournelle

Gravitic Generator  
  A device that produces an artificial gravity field.  

“However, if this local generation of a gravitic field can be used to nullify mass, we can make a spaceship that need not increase in mass as its velocity increases.

“Providing that my reasoning is any good. This is just conjecture and guess. I don’t know yet how much this gravitic generator will cover."

From Meddler's Moon, by George O. Smith.
Published by Astounding Science Fiction in 1947
