2. Genetic engineering. The other science that received its name from a science fiction story, in this case Jack Williamson’s novel Dragon’s Island, which was coincidentally published in the same year as “Liar!” The occupation of genetic engineer took a few more years to be named, this time by Poul Anderson.
3. Zero-gravity/zero-g. A defining feature of life in outer space (sans artificial gravity, of course). The first known use of “zero-gravity” is from Jack Binder (better known for his work as an artist) in 1938, and actually refers to the gravityless state of the center of the Earth’s core. Arthur C. Clarke gave us “zero-g” in his 1952 novel Islands in the Sky.
