Why '42' is the recommended number when showing something arbitrary?
I have actually seen this on the SO on sometimes. Whenever an inquiry is obscure and also the inquiry is asking some enchanting solution someone or the various other leaves a comment claiming solution is 42. Also a publication I read now makes use of '42' as the number whenever it desires show some standard principle making use of an integer. So exists any kind of history behind it or it is simply a coincidence?
