According to The Hitchhiker's Guide to the Galaxy,
researchers from a pan-dimensional, hyper-intelligent race of
beings constructed the second greatest computer in all of time and
space, Deep Thought, to calculate the Ultimate Answer to Life, the
Universe, and Everything. After seven and a half million years of
pondering the question, Deep Thought provides the answer:
"forty-two." The reaction:
"Forty-two!" yelled Loonquawl. "Is that all you've got to
show for seven and a half million years' work?"
"I checked it very thoroughly," said the computer, "and that
quite definitely is the answer. I think the problem, to be quite
honest with you, is that you've never actually known what the
question is."
After you locate the answer to the question, you may require a
TOTT for the nano.
