I was watching this pretty cool interview with Iain M. Banks, Alastair Reynolds and Peter F. Hamilton:
But it got me thinking... around the 20 minute mark, the authors touch on some science fiction inventions/terms/ideas that have actually gone from the page to real life. Along the lines of: Jules Verne's submarine (not sure if he invented the concept though) or Heinlein inventing the waterbed (according to Hamilton in the interview) or that touchscreens were brought to public awareness in Star Trek and a Hitchhiker's Guide to the galaxy or that automatic sliding doors were a science fiction concept at first. I'm sure the list goes on and on...
I'm interested to see what else was derived from science fiction media and now has application or is used in everyday life. So when my friends give me a hard time with my book choices and tell me that science fiction is just fantasy (which gets me real heated - but that's a different topic for another day), I can tell them, "Hey, without Star Trek or a Hitchhiker's Guide to the galaxy, you wouldn't have your precious touchscreen iPhone."
I'm also looking for science fiction authors who "coined" terms that are now widely used. (i.e. William Gibson coined the term "cyberspace")
