I have seen this on the SO on many times. Whenever a question is vague and the question is asking some magical answer somebody or the other leaves a comment saying answer is 42. Even a book I am reading right now uses '42' as the number whenever it wants demonstrate some basic concept using an integer. So is there any history behind it or it is just a coincidence?

It's the answer to Life, The Universe, and Everything from Douglas Adams' Hitchhiker's Guide to the Galaxy.

    If I ever write a programming language I will allow for base 13 integers. Then 6 * 9 will finally be 42, and the universe will instantly be replaced with something vastly more complex!! I've a feeling that this has already happened...

    Why in the world is this a :-(, @Nathan Taylor? Surely you're not suggesting that all programmers subscribe to some single monoculture. Oct 8, 2010 at 21:59

    @Andy Lester it's not just a single monoculture, it is the monoculture. Oct 9, 2010 at 13:07

As Fishtoaster mentioned, the number 42 has gained pop-culture status via Douglas Adams's Hitchhiker's Guide to the Galaxy, but its true origins are from Lewis Carroll (from whom Adams gained occasional inspiration).

    Some of the examples in that article are pretty sketchy, especially where it starts getting into mathematical extrapolation and alternate base numbering. Sep 2, 2010 at 19:14
