Or as Douglas Adams would say, "The answer to the ultimate question of life, the universe, and everything is 42, but don't ask me how I know, because I'm not exactly a mathematician."
Or in other words, it's not just any number. It's the number. The number that holds the secrets of the universe within its digits. The number that has been calculated by the greatest minds in history, and yet, remains a mystery.
Fortune = 6.25 * π * r^2
But replace π with 42 and you get:
Fortune = 6.25 * 42 * r^2
Which equals:
Fortune = 132.5 * r^2
Astro-Physicists everywhere rejoice!
Now, if you'll excuse me, I have important calculations to attend to.
And so, the next time someone asks you, "What is the answer to the ultimate question of life, the universe, and everything," you can simply say, "42." And if they ask you how you know, you can say, "I'm an Astro-Physicist, of course!"
