Check out this really interesting article about some science words that actually originated from science fiction.
This was a pleasant surprise:
1. Robotics. This is probably the most well-known of these, since Isaac Asimov is famous for (among many other things) his three laws of robotics. Even so, I include it because it is one of the only actual sciences to have been first named in a science fiction story (”Liar!”, 1941). Asimov also named the related occupation (roboticist) and the adjective robotic.
