Hard science fiction

Jump to: navigation, search

Hard science fiction is a category of science fiction characterized by an emphasis on scientific or technical detail, or on scientific accuracy, or on both.[1][2] The term was first used in print in 1957 by P. Schuyler Miller in a review of John W. Campbell, Jr.'s Islands of Space in Astounding Science Fiction.[3][4][5] The complementary term soft science fiction (formed by analogy to "hard science fiction"[6]) first appeared in the late 1970s as a way of describing science fiction in which science is not featured, or violates the scientific understanding at the time of writing.

The term sometimes also contrasts the "hardness" of the sciences used in the story: the "hard" sciences are quantitative or material-based disciplines, such as physics, chemistry, biology, and astronomy; while the more "soft" sciences are social sciences, such as sociology, anthropology, or psychology. Stories featuring engineering tend to be categorized as hard SF, although technically engineering is not a science. Neither term is part of a rigorous taxonomy — instead they are approximate ways of characterizing stories that reviewers and commentators have found useful. The categorization "hard SF" represents a position on a scale from "softer" to "harder", not a binary classification.

The heart of the "hard SF" designation is the relationship of the science content and attitude to the rest of the narrative, and (for some readers, at least) the "hardness" or rigor of the science itself.[7] One requirement for hard SF is procedural or intentional: a story should be trying to be accurate and rigorous in its use of the scientific knowledge of its time, and later discoveries do not necessarily invalidate the label. For example, P. Schuyler Miller called Arthur C. Clarke's 1961 novel A Fall of Moondust hard SF,[3] and the designation remains valid even though a crucial plot element, the existence of deep pockets of "moondust" in lunar craters, is now known to be incorrect. There is a degree of flexibility in how far from "real science" a story can stray before it leaves the realm of hard SF[citation needed]. Some authors scrupulously avoid such implausibilities as faster-than-light travel, while others accept such notions (sometimes called "enabling devices", since they allow the story to take place[citation needed]) but focus on realistically depicting the worlds that such a technology might make possible. In this view, a story's scientific "hardness" is less a matter of the absolute accuracy of the science content than of the rigor and consistency with which the various ideas and possibilities are worked out.

Readers of "hard SF" often try to find inaccuracies in stories, a process which Gary Westfahl says writers call "the game". For example a group at MIT concluded that the planet Mesklin in Hal Clement's 1953 novel Mission of Gravity would have had a sharp edge at the equator, and a Florida high-school class calculated that in Larry Niven's 1970 novel Ringworld the topsoil would have slid into the seas in a few thousand years.[8]
