It occurs to me that this year I’ve spent plenty of time on fantasy, while neglecting science fiction. A trend likely to continue until 2014 at least....
So for today, let’s spend a little time redressing the balance, and talk about hard SF by women.
Defining hard science fiction, rather like defining epic fantasy, is a tricksy business. (Or hobbit.) The Encyclopedia of Science Fiction itself acknowledges the potential impossibility of any rigorous definition, concluding only:
“[T]the most important thing about it is, not that it should include real science in any great detail, but that it should respect the scientific spirit; it should seek to provide natural rather than supernatural or transcendental explanations for the events and phenomena it describes.” [Link.]
