In his classic book The Hitchhiker’s Guide to the Galaxy, Douglas Adams wrote “the answer to the ultimate question of life, the universe and everything is 42.” For years, people have been trying to decipher the “hidden” meaning behind the number 42, but Adams himself, late in life, said “The answer to this is very simple. It was a joke. It had to be a number, an ordinary, smallish number, and I chose that one. Binary representations, base 13, Tibetan monks are all complete nonsense. I sat on my desk, stared in to the garden and thought 42 will do. I typed it out. End of story.” Nonsense or not, Google’s calculator returns the number 42 in response to this query.
