Science Fiction Plus, August 1953

This August 1953 issue of Science-Fiction+ features editor Hugo Gernsback's essay on "Science-Fiction Semantics," proposing new terminology for space-faring contexts. Gernsback critiques imprecise language in SF literature—arguing against using Earth-specific terms like "year" on other planets, proposing "orbitemp" for planetary orbital periods and "light unit" as an alternative astronomical measurement. He coins neologisms for radiation dangers: "solex" (solar X-ray), "ulvio" (ultraviolet), and "cosrar" (cosmic radiation).

The issue's featured story is Clifford D. Simak's complete short novel "Spacebored Generations," examining sociological effects on passengers aboard a thousand-year interstellar ark. The crowded ship operates under strict conservation laws; inhabitants cannot have children until elderly members die, creating moral tension. The narrative opens with a mechanical disturbance—"the Mutter"—disrupting the generations-long stasis. Additional contents include stories by Albert de Pina and Henry Hasse, Chad Oliver, and the conclusion of a serialized novel by Pierre Devaux and H.G. Viot, plus science features and news columns.
