io9 just came up with an interesting articles titled "10 Words You Might Think Came from Science (But Are Really From Science Fiction ):
Last week it came to our attention that the phrase "blast off" was coined—not in a purely scientific context, but a science fictional one—by E. E. Smith, an early science fiction author often referred to as "the father of space opera." The term appeared in Smith's 1937 story Galactic Patrol, when one character inquires of another, "How long do you figure it'll be before it's safe for us to blast off?"
And it turns out blast off isn't the only scientific word or phrase with science fictional origins; here is a list of nine more, originally composed by Jeff Prucher—editor for the Oxford English Dictionary's Science Fiction Project and author of the Hugo Award—winning Brave New Words: The Oxford Dictionary of Science Fiction—for the Oxford University Press Blog.
Follow this link to find out which words made it on the list! I was a bit taken aback by some of them. . .
