42

(noun): The alphanumerical sum of "To Be" (T=20, O=15 → 35; B=2, E=5 → 7; 35 + 7 = 42). Famously coined by Douglas Adams as the "Answer to the Ultimate Question of Life, the Universe, and Everything," it’s an ordinary number with extraordinary meaning. Fun fact: Adams chose it randomly, proving even the universe’s biggest joke can start with a glance out the window.

I sat at my desk, stared into the garden and thought '42 will do' I typed it out. End of story.
--Douglas Adams (1993)
