101010

The ultimate answer to life, the universe, and everything is not 42, but rather, 101010b. At least, I like it better: 101010. It can’t be a coincidence. some more info on 42

From Wikipedia

Douglas Adams was asked many times during his career why he chose the number forty-two. Many theories were proposed, but he rejected them all. On November 2, 1993, he gave an answer on alt.fan.douglas-adams:

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 thirteen, Tibetan monks are all complete nonsense. I sat at my desk, stared into the garden and thought ’42 will do’ I typed it out. End of story.
