Author Chris Moriarty has an interesting article about hard science fiction.
…hard SF is still going strong, fueled by writers and readers who thrill to that special hard SF combination of visionary speculation backed up by nuts and bolts ‘here’s how we get there from here’ science writing. It’s still about the science, and it always will be. But it’s also about people and politics and everything else in the known and unknown universe. It’s all up for grabs. Just like it always has been. . . .
Of related interest, I Googled around and found an Intro to Hard SF for the non-SF Reader, Hard vs. Soft SF as well as Grading SF for Realism. We’ve also discussed it here at SF Signal.
