"It means 'Ask the next question.' It's the symbol of everything humanity has ever created,
and is the reason it has been created. This guy is sitting in a cave and he says, 'Why can't man fly?' Well, that's the question.
The answer may not help him, but the question now has been asked. And so all through the ages, people have been trying to find out the answer to that question.
We've found the answer, and we do fly. That's it. Ask the next question. And the one after that." - Theodore Sturgeon
