The term is formed by analogy to the popular distinction between the "hard" (natural) and "soft" (social) sciences. Science fiction critic Gary Westfahl argues that neither term is part of a rigorous taxonomy; instead they are approximate ways of characterizing stories that reviewers and commentators have found useful. - The brothers Arkady (28 August 1925 12 October 1991) and Boris (14 April 1933 19 November 2012) Strugatsky (alternate spellings: Strugatskiy, Strugatski, Strugatskii) were Soviet-Russian science fiction authors who collaborated through most of their careers. - The Noon Universe (Russian term: " " or " " "World of Noon") is a fictional future setting for a number of hard science fiction novels written by Arkady and Boris Strugatsky.
